Problems solved by technology

The main disadvantage of the direct-acting type is low reliability, and there are many cases of jamming in the isolation opening and closing
The main disadvantage of the separate knife switch structure is that the size of the mechanism is relatively large, occupying the air box, and the sheet metal space is relatively large, resulting in the overall structure of the switch cabinet becoming larger

Abstract

The invention provides a three-station isolated circuit breaker switch. The switch comprises an insulating frame, a first support and a first crank arm, wherein the first support is installed in the insulating frame, the first crank arm is installed on the first support, a second support installed in the insulating frame is arranged below the first support, and the second crank arm is installed onthe second support; the first connecting lever and the second connecting lever are both connected with a transmission assembly, the first connecting lever is connected with a circuit breaker vacuum bubble through the transmission assembly, the second connecting lever is connected with an isolation vacuum bubble and a grounding vacuum bubble through the transmission assembly, the other end of theisolation vacuum bubble is connected with the circuit breaker vacuum bubble, and the other end of the grounding vacuum bubble is connected with a conducting bar. The vacuum circuit breaker is simple in structure, high in reliability and simple in switch production process, the structure is modularized, the assembly efficiency is greatly improved, and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of circuit breaker switches, in particular to a three-station isolated circuit breaker switch. Background technique [0002] The main structure of the circuit breaker switch on the market is a combination of a vacuum circuit breaker and a knife-gate isolation grounding vacuum bulb. As the switch industry's requirements for various parameters continue to rise, the advantages of fracture insulated switches that isolate vacuum bubbles are more obvious. With the development of vacuum switch technology, the structure of full vacuum insulation will also occupy a place in the power market. The isolating switch in the switch on the market is used, the conductive column direct-acting type, and the separate knife switch structure. The main disadvantage of the direct-acting type is low reliability, and there are many jamming situations in the isolation opening and closing. The main disadvantage of the separate knife ...
