Icar electrical components refer to switching devices capable of closing, carrying, and breaking current under normal circuit conditions, and capable of closing, carrying, and breaking current under abnormal circuit conditions within a specified time. Circuit breakers are classified into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague; generally, equipment above 3kV is referred to as high-voltage electrical apparatus. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. They can automatically cut off the circuit when serious faults such as overload, short circuit, or undervoltage occur. Their function is equivalent to a combination of fuse switches and over/under thermal relays. Moreover, component replacement is generally not required after interrupting fault currents. They have been widely applied. In the generation, transmission, and use of electricity, power distribution is an extremely important link. The distribution system includes transformers and various high and low-voltage electrical equipment, while low-voltage circuit breakers are a type of electrical apparatus with large usage volume and wide application.

Icar electrical component classification

Based on the power supply used, motors can be classified into DC motors and AC motors. Among them, AC motors are further divided into single-phase motors and three-phase motors. According to their structure and working principles, motors can be categorized as DC motors, asynchronous motors, and synchronous motors. Synchronous motors can also be subdivided into permanent magnet synchronous motors, reluctance synchronous motors, and hysteresis synchronous motors. Asynchronous motors can be divided into induction motors and AC commutator motors. Induction motors include three-phase asynchronous motors, split-phase asynchronous motors, and shaded-pole asynchronous motors. AC commutator motors are further classified into single-phase series-wound motors, universal motors (AC/DC), and repulsion motors. Based on starting and operating methods, motors can be categorized as capacitor-start single-phase asynchronous motors, capacitor-run single-phase asynchronous motors, capacitor start-and-run single-phase asynchronous motors, and split-phase single-phase asynchronous motors. Motors can also be classified by application into drive motors and control motors. Drive motors are further divided into motors for power tools, household appliances, and other general small mechanical equipment. Control motors include stepper motors and servo motors, among others. By rotor structure, motors can be classified as squirrel-cage induction motors and wound-rotor induction motors. Finally, based on operating speed, motors can be categorized as high-speed motors, low-speed motors, constant-speed motors, and variable-speed motors.

Icar electrical component types

Inductors can be made by winding conductive material, typically copper wire, around a magnetic core. The magnetic core can also be removed or replaced with ferromagnetic material. Core materials with higher permeability than air can confine the magnetic field more tightly around the inductor component, thereby increasing inductance. There are many types of inductors; most are made with enamel-coated coils wound around ferrite bobbins, while some shielded inductors place the coil completely inside the ferrite. The cores of some inductor components are adjustable, allowing the inductance value to be changed. Small inductors can be directly etched onto PCB boards using a method of laying spiral traces. Small-value inductors can also be manufactured in integrated circuits using the same process as for transistors. In these applications, aluminum interconnects are often used as conductive material. Regardless of the method, due to practical constraints, the most commonly used approach is a circuit called a "gyrator," which uses a capacitor and active components to exhibit the same characteristics as an inductor component. Inductor components used for blocking high frequencies are often constructed from a metal wire passing through a magnetic column or bead.

Icar electrical component structure

1. Liquid crystal panel: The liquid crystal panel includes polarizing film, glass substrates, black matrix, color filters, protective film, common electrodes, alignment layer, liquid crystal layer (liquid crystal, spacers, sealant), capacitors, display electrodes, prism layer, and diffuser layer. The polarizing film, also known as a polarizer, is divided into an upper polarizer and a lower polarizer. The polarization functions of the upper and lower polarizers are perpendicular to each other. They act like a fence, blocking light wave components as required, for example, blocking light wave components perpendicular to the polarizer fence and only allowing light wave components parallel to the fence to pass through. 2. Glass substrate: In liquid crystal displays, glass substrates are divided into upper and lower substrates. Their main function is to hold the liquid crystal material in the space between the two substrates. The material for glass substrates is generally alkali-free borosilicate glass with excellent mechanical properties, heat resistance, and chemical corrosion resistance. For TFT-LCD, one glass substrate is distributed with TFT, while the other glass substrate is deposited with color filters. 3. Black matrix: The black matrix uses highly light-blocking materials to separate the red, green, and blue primary colors in the color filter (to prevent color mixing) and to prevent light leakage, thereby helping to improve the contrast of each color block. In addition, in TFT-LCD, the black matrix can conceal internal electrode wiring or thin-film transistors. Color filters, also known as color films, function to generate 3 primary base colors of red, green, and blue, achieving full-color display for the liquid crystal display. 4. Alignment film: The alignment film, also known as the orientation film or alignment layer, functions to allow liquid crystal molecules to achieve uniform arrangement and orientation at the microscopic level. 5. Transparent electrodes: Transparent electrodes are divided into common electrodes and pixel electrodes. The input signal voltage is applied between the pixel electrode and the common electrode. Transparent electrodes are usually formed by depositing indium tin oxide (ITO) material on the glass substrate to create a transparent conductive layer. 6. Liquid crystal material: Liquid crystal material acts like a light valve in LCD, controlling the brightness of transmitted light to achieve information display. 7. Driver IC: The driver IC is essentially a set of integrated circuit chip devices used to adjust and control the phase, peak value, frequency, etc., of potential signals on the transparent electrodes, establishing a driving electric field to ultimately realize information display on the liquid crystal. In liquid crystal panels, active-matrix liquid crystal displays are constructed by sealing twisted nematic (TN) liquid crystal material between two glass substrates. Among them, the upper glass substrate close to the display screen is deposited with red, green, and blue (RGB) tri-color filters (also known as color films), a black matrix, and a common transparent electrode. The lower glass substrate (the substrate farther from the display screen) is equipped with thin-film transistor (TFT) devices, transparent pixel electrodes, storage capacitors, gate lines, signal lines, etc. Alignment films (or alignment layers) are prepared on the inner sides of the two glass substrates to orient the liquid crystal molecules. Liquid crystal material is injected between the two glass substrates, and spacers are distributed to ensure uniform gap thickness. The periphery is bonded with frame sealant for sealing purposes; the common electrodes of the upper and lower glass substrates are connected using silver dot paste technology. Polarizers (or polarizing films) are attached to the outer sides of the upper and lower glass substrates, respectively. When a voltage is applied between the pixel transparent electrode and the common transparent electrode, the arrangement state of the liquid crystal molecules changes. At this time, the intensity of incident light passing through the liquid crystal also changes. Liquid crystal displays utilize the optical rotation property of liquid crystal material, combined with electric field control, to achieve information display. 8. Backlight module: LCD products are non-emissive electronic devices that do not possess light-emitting characteristics themselves. They must rely on light emission from the source in the backlight module to achieve display performance. Therefore, the brightness of LCD is determined by its backlight module. Thus, the performance of the backlight module directly affects the display quality of the liquid crystal panel. The backlight module includes illumination light sources, reflectors, light guide plates, diffusion sheets, brightness enhancement films (prism sheets), and frames. The backlight modules used in LCD can be mainly divided into two categories: edge-lit backlight modules and direct-lit backlight modules. Mobile phones, laptops, and monitors (15 inches) mainly use edge-lit backlight modules, while LCD TVs mostly use direct-lit backlight module light sources. Backlight module light sources mainly use cold cathode fluorescent lamps and light-emitting diodes as the backlights for LCD. 9. Reflector: The reflector, also known as the reflector hood, mainly functions to direct all light emitted by the light source into the light guide plate, minimizing useless loss as much as possible. 1. Light guide plate: The main function of the light guide plate is to guide light emitted from the side light source to the front of the panel. 11. Prism sheet: The prism sheet, also known as the brightness enhancement film, mainly functions to concentrate scattered light through refraction and total reflection within the film layer, emitting it from the backlight source at a specific angle to achieve a screen brightening display effect.14. Diffusion sheet: The main function of the diffusion sheet is to correct the edge-lit light from the backlight module into a uniform surface light source to achieve optical diffusion effects. Diffusion sheets are divided into upper diffusion sheets and lower diffusion sheets. The upper diffusion sheet is located between the prism sheet and the liquid crystal assembly, closer to the display panel. The lower diffusion sheet is located between the light guide plate and the prism sheet, closer to the light source.
