[0002] The disconnecting switch integrates a grounding position into the traditional two-position disconnecting switch. The three-position disconnecting switch has three working positions: closed, grounded, and intermediate isolated. The operating mechanism of the disconnecting switch is used to position the three phase contacts in the three states of energization, isolation, and grounding respectively. To ensure safety when the cable compartment door is open, the disconnecting switch must be in a grounded state; however, existing cable compartment doors do not have corresponding safety features. Summary of the Invention

[0003] To address the technical problem of the lack of safety features on cable compartment cabinet doors in existing technologies, this application proposes an interlocking device for cable compartment cabinet doors, which solves the aforementioned technical problem.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] This utility model provides an interlocking device for a cable compartment cabinet door, configured on a disconnecting switch, comprising: a rotating plate, the rotating plate being rotatably configured on the disconnecting switch and driven by the rotating shaft of the disconnecting switch; a sliding plate, the sliding plate being limited on the disconnecting switch to perform horizontal linear movement, the sliding plate being pushed by the rotated rotating plate, the sliding plate having a limiting groove, the limiting groove including a connecting locking track and an unlocking track, the locking track extending horizontally, the unlocking track extending vertically; a locking rod, the locking rod being limited on the disconnecting switch to perform vertical linear movement, one end of the locking rod slidably engaging in the limiting groove, the other end of the locking rod having a locking pin; and a latch, the latch being connected to the cable compartment cabinet door, the latch having a locking groove for the locking pin to enter and exit.

[0006] Furthermore, one end of the rotating plate is formed as a force-bearing end, and the force-bearing end is fixedly connected to the rotating shaft in the disconnecting switch.

[0007] Furthermore, the rotating shaft in the disconnecting switch that is fixedly connected to the force-bearing end of the rotating plate is a sector-shaped rotating shaft.

[0008] Furthermore, the translation plate is provided with a plurality of guide grooves extending in the horizontal direction, and correspondingly, the disconnect switch is provided with a plurality of guide pins, each guide pin fitting into the corresponding guide groove.

[0009] Furthermore, a groove is formed at one end of the translation plate that is pushed by the rotating plate, and a push pin is disposed on the end of the rotating plate accordingly, the push pin engaging in the groove.

[0010] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:

[0011] The interlocking device for the cable compartment cabinet door of this utility model, when the isolating switch is not in the grounding position, the locking rod is engaged in the locking track and is limited by the edge of the locking track, preventing vertical movement. That is, the locking pin of the locking rod is inserted into the locking groove of the latch, locking the cable compartment cabinet door and preventing it from being opened. When the rotating shaft in the isolating switch rotates to achieve the grounding function, it drives the rotating plate to rotate. The rotated rotating plate pushes the translation plate to make a horizontal linear movement, so that the locking rod engaged in the limiting groove of the translation plate moves to the intersection of the locking track and the unlocking track. The locking rod is pushed into the vertically extending unlocking track, that is, the locking pin of the locking rod is pulled out from the locking groove of the latch, releasing the restriction on the cable compartment cabinet door, and the cable compartment cabinet door can be opened. In summary, the interlocking device for the cable compartment cabinet door of this utility model ensures that the cable compartment cabinet door can only be opened when the isolating switch is in the grounding position, thereby solving the technical problem of the lack of safety settings for cable compartment cabinet doors in the prior art.
