A circuit breaker having an automatic circuit breaker rating

Abstract

The invention discloses a circuit breaker with automatic circuit breaker rating, its structure comprises electrical connection means, Circuit break body, secondary circuit terminal, Securing connecting plate, data display, fast power-off protection against electric sparks, The upper surface of the electrical connection device is provided with a circuit breaker body and is connected by electric welding, the secondary circuit terminal is installed on the upper surface of the circuit breaker body and is bonded by screw thread connection, and the fixed connection plate is installed on the left side of the circuit breaker body and is connected by electric welding. As that circuit break is not tripped when the circuit break is in operation, By detecting the rated value to start the power-off quickly, the equipment is prevented from being burnt and difficult to be repaired, meanwhile, the air is extracted to reach the simulated empty state, the generation of electric spark is prevented from causing the internal combustion, and the alarm is started at the same time of the forced power-off, so that the staff can repair the reason of the incomplete tripping power-off.

Description

technical field [0001] The present invention relates to the field of circuit breaker equipment, more specifically a circuit breaker with automatic circuit breaker rating. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. However, the current circuit breaker has the following disadvantages: [0003] 1. The circuit breaker is installed to detect the voltage and current value. When the equipment is used to make it higher than the rated voltage, the fault of the circuit breaker does not complete the trip and cut off the power, so that the equipment and the circuit breaker will generate high temperature and burn the wire and cause serious failure, which requires replacement Complicated and difficult. [0004] 2. When the circuit breaker fails to complete the trip and cut off the power...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies existing in the prior art, the object of the present invention is to provide a circuit breaker with an automatic circuit breaker rated value, so as to solve the problem of detecting the voltage and current value of the circuit breaker installed in the prior art, and the use of equipment operation to make it higher than the rated voltage When the circuit breaker fails to trip and cut off the power, the equipment and the circuit breaker will cause high temperature and burnt wires to cause serious faults, making replacement complicated and difficult. Cases where gap electric sparks are likely to occur and cause internal combustion
