The invention relates to a new energy box-type transformer substation circuit breaker interlocking device and a working method thereof. The new energy box-type transformer substation circuit breaker interlocking device comprises a circuit breaker arranged in a box-type transformer substation cabinet body and a box-type transformer substation cabinet door arranged at the front end of the box-type transformer substation cabinet body, a left tongue piece of the circuit breaker is fixedly connected with a door plate interlocking rod, and an interlocking sliding plate is transversely arranged abovethe circuit breaker; the left end of the interlocking sliding plate is fixedly connected with a circuit breaker connecting rod at the left end of the circuit breaker; the upper side of the right endof the interlocking sliding plate is fixedly connected with a plug pin plate; the left end of the inner side of the box-type transformer substation cabinet door is fixedly connected with an interlocking pressing plate used for pressing a door plate interlocking rod backwards when the box-type transformer substation cabinet door is closed, the right end of the inner side of the box-type transformersubstation cabinet door is fixedly connected with a longitudinally-arranged interlocking bent plate, and the rear end of the interlocking bent plate is provided with a plug pin opening facilitating transverse penetrating of the plug pin plate. The interlocking device is reasonable in structural design, realizes reliable mechanical interlocking with the box-type transformer substation cabinet doorwhile realizing interlocking reversing of the circuit breaker, and has a relatively strong anti-misoperation function, so that a box-type transformer substation product is safer and more reliable.
Description
Technical field: [0001] The invention relates to an interlocking device for a circuit breaker of a new energy box substation and a working method thereof. Background technique: [0002] With the increase of box-type transformer capacity in the new energy field, high-voltage circuit breaker protection is more widely used, and more and more photovoltaic and wind power projects use circuit breaker protection. However, the interlock protection of the existing box transformer circuit breaker is usually located on its left side, which has a great impact on the maintenance operation and appearance of the box transformer, and further affects the reliability and safety of the box transformer products. Invention content: [0003] The present invention makes improvements to the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the present invention is to provide a new energy box substation circuit breaker interlocking device and its wo...
