Abstract
The invention relates to the technical field of solid insulation ring net cabinets, and discloses an interlocking mechanism which is used for carrying out interlocking on an isolation operation end and a ground connection operation end of a three-station operating mechanism. The isolation operation end and the ground connection operation end are respectively located in an isolation hole and a ground connection hole of a support. The interlocking mechanism comprises rotatable baffles, a first indicator board and a second indicator board. The baffles are arranged on the support through shaft pins in a rotatable mode and located on the outer side of the isolation operation end and the outer side of the ground connection operation end. A first stop pin and a second stop pin which are capable of abutting against the outer edges of the baffles are respectively arranged on the inner side of the first indicator board and the inner side of the second indicator board. Through the adjustment of the position of the first stop pin and the position of the second stop pin, the baffles can be located at three positions, namely, a position where only the isolation operation hole can be blocked, a position where only the ground connection operation hole can be blocked, and a position where the isolation operation hole and the ground connection operation hole can be blocked at the same time. The interlocking mechanism can achieve interlocked operation of a three-station switch operation mechanism.
