Abstract

The invention relates to a device for interlocking a chassis vehicle with a cabinet door of a circuit breaker chamber. A front baffle plate of a positioning frame is provided with a locking plate; an elastic member is sleeved on a connector; an external supporting plate covers the locking plate and is connected with the front baffle plate; a first stop block of a lead screw position-limiting mechanism is connected with a first rotary shaft through a first connecting shaft; a second connecting shaft installed on the first rotary shaft is arranged in a spiral guide groove of a first sleeve; an offsetting spring is installed between the first rotary shaft and the first sleeve; the first sleeve in a free state drives the first stop block to be installed between the locking plate and the frontbaffle plate; a second rotary shaft of a cabinet door position-limiting mechanism is installed on the external supporting plate; a second stop block is connected with the second rotary shaft through the first connecting shaft; the second connecting shaft installed on the second rotary shaft is arranged in a spiral guide groove of a second sleeve; an offsetting spring is installed between the first rotary shaft and the second sleeve; and the second sleeve in a free state drives the second stop block to be installed in a position-limiting groove of the cabinet door baffle plate. The device forinterlocking the chassis vehicle with the cabinet door of the circuit breaker chamber has the advantages of rational and compact structure, reliability for interlocking, and reduction of production cost.

Description

technical field [0001] The invention relates to an interlocking device for a chassis car and a cabinet door of a circuit breaker room, and belongs to the technical field of medium and high voltage removable switchgear. Background technique [0002] The medium and high voltage switchgear is usually composed of a control room, a circuit breaker room, a busbar room and a cable room. A group of static contact seats as a static contact device are fixed in the circuit breaker room. The static contacts of the incoming and outgoing lines on the static contact seat are The head is connected with the external high-voltage power supply circuit. When the circuit breaker chassis is pushed into the circuit breaker room, the upper and lower contacts of the circuit breaker chassis are respectively engaged with the static contacts of the incoming and outgoing lines. After the circuit breaker is closed, the connection on the circuit is realized. After operating the propulsion mechanism to pu...
