Description
Technical Field
[0001] The utility model relates to the technical field of GCB arc extinguishing chamber maintenance tooling, in particular to a GCB arc extinguishing chamber opening and closing operation tooling. Background Art
[0002] During the overhaul of the GCB arc extinguishing chamber, the arc extinguishing chamber is lifted out of the box and placed in the overhaul room. At this time, the GCB arc extinguishing chamber is not connected to the operating mechanism, so there is no power source for opening and closing operations. When the GCB arc extinguishing chamber is hoisted out of the box as a whole, it needs to be in the closed position. In addition, when the moving contact module is disassembling and assembling the moving main contact and the pressure cylinder, the GCB arc extinguishing chamber needs to be in the closed position. When the moving arc contact of the GCB arc extinguishing chamber is disassembled and assembled, it should be in the open position. When measuring the contact erosion life of the moving contact of the GCB arc extinguishing chamber, the GCB arc extinguishing chamber should be operated in the open and closed positions for measurement multiple times. All of the above overhaul processes require the opening and closing of the GCB arc extinguishing chamber, so a special GCB arc extinguishing chamber opening and closing operation tool is required.
