Abstract

An interlocking mechanism of an integrated switching mechanism of the invention is characterized in that the interlocking mechanism works together with an operating mechanism to limit the operation sequence of an arc extinguishing chamber, an isolation switch, a ground switch and a lower cabinet door; the operating mechanism is provided with a ground operating hole and an isolation operating hole,an operating handle can pass through the ground operating hole to turn on / off the ground switch, and the operating handle can pass through the isolation operating hole to turn on / off the isolation switch; and the interlocking mechanism includes a lower door interlocking plate, an interlocking roof plate, a ground interlocking plate, an intermediate interlocking plate and an isolation interlockingplate. The interlocking mechanism has the advantages of reliable interlocking and convenient operation.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a high-voltage switch cabinet. Background technique [0002] In power systems, switchgears are widely used as power distribution equipment. The main function of switchgear is to switch, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices. [0003] There are various structures of existing switch cabinets, and customers continue to put forward new requirements for the design of switch cabinets. For example, some customers have very high requirements for the volume of the switchgear, requiring the size of the switchgear to be less than 500x900x1800mm, but the various parameters of each electrical component (inc...
