Abstract

Provided are a disconnecting switch and an interlocking mechanism of a circuit breaker, wherein the disconnecting switch and the interlocking mechanism of the circuit breaker are simple in structure and convenient to operate and improve reliability. The disconnecting switch and the circuit breaker are arranged in a cabinet body, the cabinet body is provided with an upper cabinet body and a lower cabinet body, the disconnecting switch is arranged in the upper cabinet body, the circuit breaker is arranged in the lower cabinet body, the circuit breaker is provided with a separating brake accessory shaft, and the disconnecting switch and the circuit breaker are separated through a partition board. The upper cabinet body is opened and closed through an upper front door, and the lower cabinet body is opened and closed through a lower front door. The interlocking mechanism comprises an upper front door interlocking part, a lower front door interlocking part and a control assembly. The interlocking mechanism controls the upper door interlocking part and the lower door interlocking part at one time through the control assembly. The disconnecting switch and the interlocking mechanism of the circuit breaker are simple to operate and high in reliability and avoid misoperation accidents.

Description

technical field [0001] The invention relates to the field of high-voltage electrical equipment manufacturing, in particular to an interlock mechanism of a high-voltage switch cabinet. Background technique [0002] The "interlock" of high-voltage switchgear is an important measure to ensure equipment and personal safety and prevent misoperation. To ensure the safe operation of the switchgear, it is necessary to operate strictly according to the regulations, but sometimes the operator violates the operating procedures or the reliability of the interlock mechanism is low, resulting in personal injury and equipment damage. Therefore, it is necessary to improve the reliability of the mechanical interlock of the switchgear. [0003] At the same time, in the prior art, the circuit breaker and the isolating switch in the switchgear need to be controlled by the control switch respectively. The two procedures make the operation cumbersome, increase the probability of misoperation...
