Abstract

The invention provides a circuit breaker with automatic zero-crossing switching, which comprises a processor, an opening driver, an opening actuator, a closing driver, a closing actuator, a zero-crossing detection circuit and a release, and is characterized in that the opening driver is respectively connected with the processor and the opening actuator, the closing driver is respectively connected with the closing actuator and the processor, and the zero-crossing detection circuit is connected with the processor. The zero cross detection circuit and the release are both connected with the processor, the opening actuator and the closing actuator are connected with a zero line of alternating current power supply voltage, and the opening driver and the closing driver are connected with a live line of the alternating current power supply voltage. The technical problems that in the prior art, a circuit breaker is large in size, low in execution speed and low in reliability are solved.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a circuit breaker with automatic zero-crossing switching. Background technique [0002] Intelligent circuit breakers are generally composed of contact systems, arc extinguishing systems, operating mechanisms, trip units, casings, etc. The function of circuit breakers is to cut off and connect load circuits, and cut off faulty circuits to prevent accidents from expanding and ensure safe operation. [0003] In the prior art, the control circuit breaker tripping is generally driven by a motor to realize the switch and multi-function protection. The execution consumes a lot of power, is slow, and the execution time is uncertain. The volume is large, the cost is high, the production efficiency is low, and the reliability is low. Therefore, how to effectively simplify the assembly process, improve production efficiency, and optimize execution speed, reliability, and power cons...
