Research on Modular and Intelligent Design of High Voltage Circuit Breaker Mechanism

Abstract

For the power system, in addition to the need for a circuit breaker to start protection to cut off the circuit when the equipment or line fails, other power outages are hoped to be avoided. At this stage, the mechanism replacement of the circuit breaker and the isolating switch still needs to be performed in the case of power failure, and the degree of modularity of the product is not high. Therefore, the modular design of the high-voltage switch not only has the value of technical research, but also has very important practical application value. In this article, we have studied a modular and intelligent scheme of circuit breaker mechanism. The integrated transformation plan of the secondary system of the circuit breaker mechanism is proposed according to the function. A scheme to ensure the output consistency of the circuit breaker mechanism is proposed to ensure the interchangeability between different mechanisms. And the monitoring IED for the breaker mechanism is designed. It has a good promotion for the digital development of circuit breaker equipment.
