Special junction pole for testing mechanical characteristic of circuit breaker

Abstract

The invention relates to a special junction pole for testing the mechanical characteristic of a circuit breaker. The special junction pole comprises an upper junction pole, a middle junction pole anda lower junction pole which are successively connected. A clip is arranged at the upper end of the upper junction pole. Lower connection parts are arranged at the lower ends of the upper junction poleand the middle junction pole. Upper connection parts matching the lower connection parts are arranged at the upper ends of the middle junction pole and the lower junction pole. A wire is arranged between the upper connection part and the lower connection part located in the middle junction pole. A wire is disposed between the lower connection part and the clip located in the upper junction pole.The internally communicating junction poles replace an original test wire. In use, it is just required to connect the upper junction pole, the middle junction pole and the lower junction pole so as toachieve a purpose of installing the test wire while erecting the poles. It is very convenient to use and fold the special junction pole. The junction poles are connected via internal wires so as to be connected with a circuit breaker instead of the test wire. The special junction pole is firmly connected and cannot fall off.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to a special wiring rod for testing the mechanical characteristics of a circuit breaker. Background technique [0002] The mechanical characteristic test of the circuit breaker is a must-do item in the circuit breaker test. Before the test, the test wiring needs to be connected to both ends of the circuit breaker port. The wiring position of the 35kV and above outdoor open circuit breaker is relatively high, and a high-altitude wiring pole is required. The original wiring method is: the test wiring is fixed to the upper and lower wiring boards of the circuit breaker through the top clamp of the wiring rod. The external test wiring is easy to fall off, and there is a safety risk if the adjacent interval is charged. At the same time, the test wiring is long, and the wiring and take-up are cumbersome, which affects work efficiency. Contents of the invention [0003] The...

Problems solved by technology

The original wiring method is: the test wiring is fixed to the upper and lower wiring boards of the circuit breaker through the terminal clamp at the top of the wiring rod. The external test wiring is easy to fall off. If the adjacent interval is electrified, there will be a safety risk.

At the same time, the test wiring is long, and the wiring and wiring are cumbersome, which affects work efficiency.
