Description
Technical Field
The invention relates to the technical field of power equipment, in particular to a 35kV circuit breaker loop resistance test high-altitude wiring clamp with a polishing device.
Background
Because the material of the wiring board of the 35kV circuit breaker is different from that of the circuit breaker with the voltage level of more than 110kV, the wiring board can have an oxide film of 1-2 mm and even thicker after long-term operation. At present, when an overhaul tester tests the loop resistance of the circuit breaker, a loop resistance test wire is usually connected to the high-altitude wiring clamp for testing, however, as the oxide film is too thick, the tooth mouth of the high-altitude wiring clamp cannot bite the oxide layer, so that the measurement result is large, and the tester can misjudge the health condition of the circuit breaker. In the case where the oxide film is excessively thick, the test cannot be performed even. At this time, a tester is required to climb up the circuit breaker to manually polish the oxide film on the wiring board. Personnel ascend and polish and have the security risk of ascending a height, and efficiency is extremely low, has greatly prolonged test time.

However, in practice, it has been found that when polishing a wiring board by a polisher, since there is no member such as fixing, clamping, or limiting, a problem such as runout of the polishing member occurs during polishing, and it is difficult to achieve uniform polishing. When the polishing surface is not uniformly polished, if the polishing time is short, partial parts cannot be polished, and if the wiring clamp tooth openings are in contact with the parts which are not sufficiently polished, the test is still inaccurate; if polishing time is long, the polishing surface can be polished cleanly, but on the one hand, the testing efficiency is reduced, and on the other hand, because the top of the high-altitude wiring clamp is provided with the polishing device, the top weight is large, and the high-altitude wiring clamp is supported for a long time to polish, so that the high-altitude wiring clamp is extremely physical-strength-consuming.
