Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, specifically to a remote operation control cabinet for switchgear. Background Technology

[0002] The basic structure of air-insulated high-voltage switchgear includes a fixed cabinet and a removable circuit breaker trolley. This type of switchgear has a circuit breaker compartment. Inside the circuit breaker compartment are guide rails for moving the circuit breaker trolley between the test / isolation position and the working position. The removable circuit breaker trolley includes a frame made of high-strength steel plate, poles mounted on the frame, an operating mechanism, and some auxiliary components.

[0003] When operating the switchgear, it is usually necessary to first open the door of the circuit breaker compartment, push the trolley into the compartment to engage with the guide rails, and then close the door. Simultaneously, the baffle plate obstructing the trolley's rotating shaft is pushed open, allowing the shaft to protrude through the opening in the door, enabling operators to crank it with tools. The operator can observe the trolley's position through the observation window in the compartment door. With the compartment closed, the operator observes the circuit breaker's spring energy storage mechanism, control buttons, and indicators to assess its status and then operate the trolley accordingly.

[0004] When a circuit breaker trolley is moved from the test / isolation position to the working position, there is usually some travel required. In an example switchgear, the circuit breaker trolley is moved from the test / isolation position to the working position by manually cranking the trolley's rotating shaft, which rotates the shaft 45 revolutions and translates the trolley 450 mm.

[0005] However, manually cranking the rotating shaft of the circuit breaker trolley requires considerable force, and it also requires manual judgment of the various states of the circuit breaker and its grounding switch. For some operators who are not skilled or do not have enough strength, this is a time-consuming and laborious task, especially when it is being demonstrated, it cannot achieve efficient and sufficient demonstration.

[0006] Although Chinese invention patent CN112736749B provides an intelligent control system for KYN high-voltage switchgear, which realizes intelligent control of operations such as the KYN high-voltage switchgear chassis trolley moving in and out, the grounding switch opening and closing, and the energy storage and opening and closing of the circuit breaker; its control cabinet is usually installed in the control room to meet actual operation needs, resulting in a large control cabinet that is not easy to transport and is not easy to display in conjunction with the switchgear for remote control in exhibitions, thus failing to meet the display requirements.
