Introduction

Circuit breaker is an important electrical device in the power system which plays a vital role in fault protection and arc extinction in an electrical system. The LELK1-1REC4-33464-2-V circuit breaker is one such a device which has an extensive branch of applications in the current industry. At the same time, it is important to be aware of the working principle behind it.

Application field

Basically, the LELK1-1REC4-33464-2-V circuit breaker is used in places like high voltage distribution systems, substations, and even power plants. It is equipped with a mechanism which can cut off the current during fault conditions, interrupting the wrong current and avoiding electrical fires or shocks. The application field of this breaker has become broad in the following aspects.First of all, it is used in heavy load applications. Since the breaker can handle higher currents, it can be used for powerful industrial AC systems, such as steel plants, refineries and paper mills. In these settings, higher voltages, currents and frequencies cause higher electrical and magnetic fields. As such, a more robust breaker is required to keep operations safe and protect personnel from potentially hazardous conditions.Moreover, the LELK1-1REC4-33464-2-V circuit breaker is suitable for high loads. It provides strong eddy current protection, thanks to its self-reset and point-of-use current monitoring capabilities. In addition to high-power industrial applications, the breaker can also be used for very high frequency applications, such as lighting and other types of electrical and electronic equipment.Another application for the breaker is in high-altitude operations. This type of breaker is specifically designed to work in high-altitude operations, where the air and pressure conditions are very extreme. Due to its adjustable trip settings and automatic reset capabilities, it is capable of dealing with the rapid change in the atmospheric conditions, making it a reliable choice for such applications.

Working Principle

The working principle of the LELK1-1REC4-33464-2-V circuit breaker is based on the alternating current (AC) system. It uses a resistor and a capacitor connected in series, which are controlled by the circuit breaker. When the current is interrupted, the resistor and capacitor combination act as a resonant circuit, which effectively stores energy in the capacitor and damps the circuit.When the current is resumed, this combination works as an amplifier, releasing the stored energy in pulses, thus restarting the interrupted current. The circuit breaker also contains a miniature contactor switch, which is activated by a magnetic field associated with the oscillations resulting from the resonant circuit.When the current passes through the breaker, the magnetic field from the transforming current causes the contactor switch to close, allowing a spark to jump across its gap and current to be passed. This spark is ignited for a controlled period of time, after which the current is again diverted and the spark is extinguished.

Conclusion

To conclude, the LELK1-1REC4-33464-2-V circuit breaker is a reliable device which has a wide application in the current industry. Due to its strong eddy current protection, it is suitable for operation in extreme conditions. Its working principle is based on a resistor and capacitor combination, which act as resonant circuit, storing energy and releasing it in pulses to resume the interrupted current.
