The invention relates to the field of power switches, in particular to a power safety switch which comprises a first circuit breaker, a second circuit breaker, a wire fixing assembly and an assembling assembly. The first circuit breaker is located on one side of the second circuit breaker, the wire fixing assembly is located on the inner side of the first circuit breaker and the inner side of the second circuit breaker, and the first circuit breaker and the second circuit breaker are fixedly connected through the fixing assembly and the assembling assembly. The outer walls of the tops of the first circuit breaker and the second circuit breaker are fixedly connected with connecting frames, and the assembling assembly is fixedly connected to the tail ends of the bottoms of the connecting frames; the assembling assembly comprises an ejector rod, the wire fixing assembly is arranged between the two sets of circuit breakers, the wire fixing assembly is adopted between the two sets of circuit breakers to fix wires on the circuit breakers, the extrusion area between the pressing plate and the wires is increased, a certain position or a certain point in the wires can be prevented from being pressed, and therefore the circuit breakers are prevented from being damaged. And the lead in the circuit breaker is prevented from being damaged and broken.
Description
technical field [0001] The invention relates to the field of power switches, in particular to a power safety switch. Background technique [0002] A circuit breaker refers to a switch 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. High-voltage circuit breakers and low-voltage circuit breakers, the distinction between high and low voltage is relatively vague, generally referred to as high-voltage electrical appliances above 3kV, circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, and protect power lines and motors. It can automatically cut off the circuit in the event of serious overload or short circuit and undervoltage faults. Its function is equivalent to the combination of fuse switch and overheating relay, etc., and generally does not need to change parts after breaking the fault current. Wide r...
