Embodiment
[0018] Such as figure 1 As shown, one end of the shaft 3 is fixed to the claw 1 by a screw, and the other end of the shaft 3 is fixed to the crosspiece 7 of the handle 8; The outer surface of the shaft rod 3 is sheathed with a steel sleeve 6, and one end of the steel sleeve 6 connected to the claw is provided with a fixed pin 2.
[0019] When working, pull up the handle crosspiece to compress the spring, use the shaft to drive the claws to retract, put the tool of the present invention into the gap of the arc extinguishing plate group in the arc extinguishing chamber, then release the handle crosspiece, and use the tension of the spring The claws are loosened and in working condition, and the clamping spring is used to fix many arc extinguishing sheets as a whole, preventing the arc extinguishing sheets from loosening and falling off, so that the arc extinguishing sheets of the entire arc extinguishing chamber can be taken out at one time , and when placed on the tool of the ...

The invention relates to a 10kV oil-minimum breaker overhauling tool. The structure of the 10kV oil-minimum breaker overhauling tool includes that one end of a shaft rod is provided with a hook claw, the other end of the shaft rod is fixed on a cross rail of a handle, and a position clamping spring and a spring are successively arranged on the shaft rod. The 10kV oil-minimum breaker overhauling tool brings convenience to grapping and placing of an arc extinction sheet, largely improves overhauling work time of an oil-minimum breaker, greatly lowers workload of overhaul operating staff, and shortens overhauling time. Furthermore, the 10kV oil-minimum breaker overhauling tool effectively resolves the difficulty of grapping and placing of the arc extinction sheet when a 10kV oil-minimum breaker arc extinguish chamber is overhauled. The problem that when the arc extinction sheet is placed to the arc extinguish chamber, a cylinder wall is scratched or the arc extinction sheet is damaged accidentally is also resolved fundamentally.
Description
technical field [0001] The invention relates to an electric power maintenance tool, in particular to a maintenance tool for a 10kV oil-less circuit breaker. Background technique [0002] In power maintenance work, 10kV oil-less circuit breaker is the equipment with many defects. When the arc extinguishing chamber of the 10kV oil-less circuit breaker is overhauled, the space of the arc extinguishing chamber is small, and the arc extinguishing sheet in the arc extinguishing chamber is difficult to take out. It takes a lot of time for maintenance personnel to take out the circuit breaker bit by bit by hand or artificially flip the circuit breaker as a whole to dump out the arc extinguishers. But it is very difficult to put it in place and it is difficult for the maintenance personnel to use their strength. It takes a lot of time to complete it, which seriously affects the work efficiency. [0003] Each region includes a lot of substations. When performing daily defect handlin...
