[0002] High-voltage switchgear is used for power generation, transmission, distribution, and conversion in power systems, as well as for switching, controlling, or protecting the power consumption process. With the increasing operational requirements for high-voltage switchgear and the promotion of unmanned stations, high-voltage switchgear currently has certain limitations. For example, when using a grounding knife, the high-voltage switchgear is required to have both manual and automatic operation modes. However, the high-voltage switchgear in the existing technology has no interlocking in both manual and automatic operation modes. As a result, when on-site workers are performing maintenance on the high-voltage switchgear, remote operators can still remotely operate it, posing the risk of accidents. Utility Model Content

[0036] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0037] like Figures 1-4 As shown, the embodiment of the present invention provides a grounding knife anti-misoperation structure, which is arranged on the side beam 100 of the switch cabinet, and the side beam 100 is provided with a grounding knife switch 200. The grounding knife can be opened and closed in manual mode or opened and closed in automatic mode.

[0038] The anti-misoperation structure of the grounding knife includes a control switch, a mounting part 1 and an operating part 2. The control switch (the control switch can be selected as a travel switch) is set on the side beam 100. In automatic mode, the grounding knife controls the opening and closing of the grounding knife through the motor. The motor, the control switch and the grounding knife form a secondary circuit. The secondary circuit can be connected and disconnected by triggering and disconnecting the control switch. The mounting part 1 is fixedly set on the side beam 100, and the operating part 2 is hinged to the mounting part 1. The operating part 2 is provided with an opening 211 corresponding to the grounding knife switch 200; refer to Figure 1 When the operating member 2 is rotated to abut against the side beam 100, the operating member 2 can trigger the control switch to connect the secondary circuit and realize the automatic mode, and the ground knife switch 200 is limited in the opening 211 and cannot be operated. The opening 211 can limit and observe the actual position of the ground knife switch 200; refer to Figure 2 When the operating member 2 is in a separated state from the side beam 100, the control switch is disconnected to disconnect the secondary circuit to prevent automatic operation in the automatic mode. At this time, the ground knife switch 200 is free from the restriction of the hole 211 and is in an operable state, and the ground knife switch 200 is switched to the manual mode and the ground knife operation is performed.

[0039] The anti-misoperation structure of the grounding knife can realize the conduction and disconnection of the secondary circuit by triggering and disconnecting the control switch through the operating member 2. That is, when the secondary circuit is disconnected, the remote operator cannot operate the automatic mode, thereby improving the safety of operation; and when the secondary circuit is on, the on-site operator cannot operate the grounding knife switch 200, thereby realizing the interlocking of the grounding knife switch 200, effectively avoiding the situation where the on-site operator is accidentally injured by operating the grounding knife when the manual mode or the automatic mode is unclear.

This structure enables the operating member 2 to extend into the first recessed hole 1001 when it rotates and abuts the side wall, so that the operating member 2 can abut the side beam 100, effectively preventing the magnet 212 from interfering with the side beam 100.

[0043] Optionally, two magnets 212 are provided, and the side beam 100 is provided with two first recessed holes 1001 corresponding to the magnets 212 one by one.
