M Schneider electrical components are active-matrix liquid crystal displays driven by thin-film transistors. They primarily use current to stimulate liquid crystal molecules to generate points, lines, and planes, which combine with backlights to form images. IPS, TFT, and SLCD are all subclasses of LCD. Their operating principle is that, under the influence of an electric field, the alignment of liquid crystal molecules changes, altering the transmittance (modulation) of external light sources to achieve electro-optical conversion. Then, using different excitations of the R, G, and B primary color signals through red, green, and blue color filters, color reproduction in the time and spatial domains is completed.

M Schneider electrical component parameters

Rated voltage: refers to the safe voltage allowed for the switch during normal operation. If the voltage applied across the switch exceeds this value, arcing and breakdown between the two contacts will occur. Rated current: refers to the maximum safe current allowed to pass when the switch is closed. If this value is exceeded, the switch contacts will burn out due to excessive current. Insulation resistance: refers to the resistance value between the conductive part and the insulating part of the switch. Contact resistance: refers to the resistance value between each pair of contacts when the switch is in the on state. Dielectric strength: refers to the highest voltage the switch can withstand between the conductor and ground. Service life: refers to the number of operations the switch can perform under normal working conditions.

M Schneider electrical component principles

Circuit breakers generally consist of a contact system, arc extinguishing system, operating mechanism, trip unit, and housing. During a short circuit, the magnetic field generated by the high current overcomes the counter-force spring, and the trip unit pulls the operating mechanism to trigger instantaneous tripping of the switch. During overload, the current increases, intensifying heat generation. The bimetallic strip deforms to a certain extent to push the mechanism into action (the higher the current, the shorter the action time). Electronic types use current transformers to collect the current magnitude of each phase and compare it with set values. When the current is abnormal, the microprocessor sends a signal to cause the electronic trip unit to activate the operating mechanism. The function of a circuit breaker is to cut off and connect load circuits, as well as to interrupt fault circuits, preventing accident escalation and ensuring safe operation. Arc extinguishing is a problem that high-voltage circuit breakers must address. The principle of blow-out arc extinguishing mainly involves cooling the arc to weaken thermal ionization. On the other hand, blowing the arc elongates it, strengthening the recombination and diffusion of charged particles, while simultaneously blowing away charged particles in the arc gap to rapidly restore the insulation strength of the medium. Low-voltage circuit breakers, also known as automatic air switches, can be used to connect and disconnect load circuits, and also to control motors that do not start frequently. Their functions are equivalent to the sum of part or all of the functions of electrical components such as knife switches, overcurrent relays, undervoltage relays, thermal relays, and residual current protective devices. They are important protective appliances in low-voltage distribution networks. Low-voltage circuit breakers have multiple protection functions (overload, short circuit, undervoltage protection, etc.), adjustable action values, high breaking capacity, easy operation, safety, and other advantages, so they are widely used. Structure and working principle: Low-voltage circuit breakers consist of an operating mechanism, contacts, protection devices (various trip units), arc extinguishing systems, etc. The main contacts of low-voltage circuit breakers are closed manually or via electric closing. After the main contacts close, the free-trip mechanism locks the main contacts in the closed position. The coil of the overcurrent trip unit and the heating element of the thermal trip unit are connected in series with the main circuit, while the coil of the undervoltage trip unit is connected in parallel with the power supply. When a short circuit or severe overload occurs in the circuit, the armature of the overcurrent trip unit attracts, causing the free-trip mechanism to act and the main contacts to disconnect the main circuit. When the circuit is overloaded, the heating element of the thermal trip unit generates heat, causing the bimetallic strip to bend and push the free-trip mechanism into action. When the circuit voltage is too low, the armature of the undervoltage trip unit releases, also causing the free-trip mechanism to act. The shunt trip unit is used for remote control. During normal operation, its coil is de-energized. When remote control is required, pressing the start button energizes the coil.

M Schneider electrical component performance

The main performance indicators of loudspeakers include sensitivity, frequency response, rated power, rated impedance, directivity, and distortion. (1) Rated power: Loudspeaker power is divided into nominal power and maximum power. Nominal power, also called rated power or non-distortion power, refers to the maximum input power allowed within the rated non-distortion range of the loudspeaker. The power marked on the loudspeaker's label and technical manual is this value. Maximum power refers to the peak power the loudspeaker can withstand at any instant. (2) Rated impedance: Loudspeaker impedance is generally related to frequency. (3) Frequency response: When audio signals of the same voltage but different frequencies are applied to a loudspeaker, the resulting sound pressure will change. Generally, the sound pressure produced at mid-frequencies is higher, while that at low and high frequencies is lower. The frequency range of high and low tones where the sound pressure drops to a certain value relative to the mid-frequency is called the frequency response characteristic of the loudspeaker. (4) Distortion: The phenomenon where a loudspeaker fails to faithfully reproduce the original sound is called distortion. There are two types of distortion: frequency distortion and nonlinear distortion. Frequency distortion is caused by stronger playback of signals at certain frequencies and weaker playback at others, disrupting the original proportion of high and low loudness and changing the original timbre. Nonlinear distortion is caused by insufficient consistency between the vibration of the loudspeaker's vibration system and the signal fluctuation, adding new frequency components to the output sound waves. (5) Directivity characteristics: Used to characterize the sound pressure distribution radiated by the loudspeaker in various spatial directions. The higher the frequency, the narrower the directivity; the larger the cone, the stronger the directivity.
