050S003 electrical components are devices that convert electrical energy into mechanical energy. They utilize energized coils (i.e., stator windings) to generate a rotating magnetic field, which acts on the rotor (such as a squirrel-cage closed aluminum frame) to form electromagnetic rotational torque. Motors are classified into DC motors and AC motors based on the power supply used. Most motors in power systems are AC motors, which can be synchronous motors or asynchronous motors (where the speed of the stator magnetic field does not remain synchronized with the rotor rotation speed). A motor mainly consists of a stator and a rotor. The direction of motion of a current-carrying conductor under force in a magnetic field is related to the direction of the current and the direction of the magnetic field lines (magnetic field direction). The working principle of a motor is that the magnetic field exerts force on the current, causing the motor to rotate.

050S003 Electrical Component Composition

1. Generally, a fuse consists of three parts: First is the fusible element part, which is the core of the fuse and serves to cut off the current when it melts. For fuses of the same type and specification, the fusible elements must have the same material, identical geometric dimensions, resistance values that are as low as possible and consistent, and most importantly, consistent fusing characteristics. Household fuses are commonly made of lead-antimony alloy. Second is the electrode part, usually consisting of two electrodes, which are important components connecting the fusible element to the circuit. They must have good conductivity and should not produce significant installation contact resistance. Third is the support part. Since the fusible element of a fuse is generally thin and soft, the support's function is to fix the fusible element and make the three parts a rigid whole for easy installation and use. It must have good mechanical strength, insulation, heat resistance, and flame retardancy, and should not exhibit phenomena such as fracture, deformation, combustion, or short circuits during use. 2. Arc extinguishing device: Fuses used in power circuits and high-power equipment not only have the three general parts of a fuse but also include an arc extinguishing device. This is because the circuits protected by such fuses not only have large operating currents, but also high voltage across the terminals when the fusible element melts. Often, the fusible element has melted (fused) or even vaporized, but the current has not been cut off. The reason is that arcing occurs between the two electrodes of the fuse at the moment of fusing due to the action of voltage and current. This arc extinguishing device must have strong insulation and good thermal conductivity, and exhibit negative electronegativity. Quartz sand is a commonly used arc extinguishing material. 3. Fusing indication device: Some fuses have a fusing indication device. Its function is to cause a certain change in appearance after the fuse operates (melts), making it easy for maintenance personnel to detect, such as emitting light, changing color, or popping out a solid indicator.

050S003 Electrical Component Structure

For rubber and plastic power cable conductors used for power, lighting, and internal installation of electrical equipment, copper cores are preferred. For large cross-section conductors, compacted stranded cores are advisable. Conductors for fixed installation generally adopt Class 1 or Class 2 conductor structures. Insulation materials generally include four types: natural styrene-butadiene rubber, polyvinyl chloride (PVC), polyethylene, and nitrile-PVC compounds. Heat-resistant power cables use PVC with a temperature resistance of 90 °C. Sheath materials generally include five types: PVC, cold-resistant PVC, ant-proof PVC, black polyethylene, and neoprene rubber. Black polyethylene and neoprene sheathed power cables are suitable for extreme cold resistance and outdoor overhead laying. In environments with external forces, corrosion, or humidity, power cables with rubber or plastic sheaths can be used. Rubber and plastic flexible power cables use copper cores with a flexible structure, formed by stranding multiple single wires. Flexible conductors generally adopt Class 5 or Class 6 conductor structures. Insulation materials generally include natural styrene-butadiene rubber, PVC, or soft polyethylene plastic. The cabling lay ratio multiplier is small. The outer protective layer uses cotton yarn braiding to prevent overheating and damage to the insulation layer. To facilitate use and simplify production processes, a three-core balanced structure is adopted, which saves production labor hours and improves production efficiency. Shielded insulated power cable conductors are allowed to be tin-plated in certain occasions. The surface coverage density of the shielding layer should comply with standards or meet user requirements. The shielding layer should be braided or wrapped with tinned copper wire. If an extruded sheath is added outside the shield, the shield may use soft round copper wire braiding or wrapping. To prevent internal interference between cores or pairs, structures with individual phase shielding for each core (or pair) can be produced. General-purpose rubber-sheathed rubber power cable conductors use copper flexible stranded wires with a flexible structure. Large cross-section surfaces are allowed to be paper-wrapped to improve bending performance. Insulation uses natural styrene-butadiene rubber, which has good aging resistance. Rubber for outdoor products uses neoprene or a neoprene-based mixed rubber formula. Mining rubber power cable conductors use copper cores with a flexible structure, formed by stranding multiple single wires. Flexible conductors generally adopt Class 5 or Class 14 conductor structures. Insulation materials generally use rubber. The cabling lay ratio multiplier is small. Many products use metal braiding to uniform the electric field and improve the sensitivity display of the insulation condition. There is a thicker outer sheath, and color coding is performed underground in mines so that construction personnel understand the different voltage levels of the rubber power cables in use.

050S003 Electrical Component Types

1. Rotating thermometers are made of a coiled bimetallic strip. One end of the bimetallic strip is fixed, and the other end is connected to a pointer. Due to different expansion rates of the two metals, the degree of coiling of the bimetallic strip varies at different temperatures, causing the pointer to indicate different positions on the dial. The temperature can be determined from the reading on the dial. 2. The resistance change of semiconductor thermometers differs from that of metals; as temperature increases, their resistance decreases, and the magnitude of change is relatively large. Therefore, even small temperature changes can cause significant changes in resistance, resulting in thermometers with high precision, often referred to as thermistors. 3. Thermocouple thermometers consist of two different metals connected to a sensitive voltmeter. At different temperatures, the metal junctions generate different potential differences at the ends of the metals. Since the potential difference is very small, a sensitive voltmeter is required for measurement. The temperature can be determined from the voltmeter reading. 4. Optical pyrometer: When an object's temperature is high enough to emit a large amount of visible light, its temperature can be determined by measuring the amount of thermal radiation. This type of thermometer is called an optical pyrometer. It mainly consists of a telescope equipped with a red filter and a circuit containing a small bulb, a galvanometer, and a variable resistor. Before use, the relationship between the filament brightness at different temperatures and the galvanometer reading is established. During use, align the telescope with the object to be measured and adjust the resistor until the bulb's brightness matches that of the object. The temperature of the object can then be read from the galvanometer. 5. Liquid crystal thermometers made with different formulas have different phase transition temperatures. When they undergo phase transition, their optical properties change, causing the liquid crystal to appear to change color. If liquid crystals with different phase transition temperatures are coated on a piece of paper, the temperature can be determined by the color change of the liquid crystal. The advantage of this thermometer is easy reading, while the disadvantage is insufficient accuracy. It is commonly used in ornamental fish tanks to indicate water temperature. 9. Digital thermometers use temperature sensors to convert (temperature) into digital signals, which are then displayed in numerical form on a display (such as LCD, digital tube, LED matrix, etc.). They can quickly and accurately measure the maximum human body temperature. Compared with traditional mercury thermometers, they offer advantages such as convenient digital reading, short measurement time, high measurement accuracy, memory function, and audible alerts. In particular, digital thermometers do not contain mercury, are harmless to the human body and the surrounding environment, and are especially suitable for use in hospitals and homes.
