Problems solved by technology

[0003] However, the line construction personnel encountered the following problems during on-site construction: (1) At present, different insulating operating rods are used for the opening operation of the circuit breaker on the pole and the electric inspection operation for the transmission line. It is troublesome to carry, time-consuming and laborious to carry out on-site operations, and in extreme cases, using the wrong insulation operating rod will also cause electric shock to the line construction personnel; (2) Generally speaking, the overhead height of the circuit breaker on the pole is relatively high , For example: on a 10kV pole-mounted circuit breaker, the installation height is 6-10m. When construction workers operate at night, it is difficult to accurately align the operating head on the insulating operating rod with the opening and closing contacts on the circuit breaker. Seriously affected the operation efficiency; (3) When the line construction personnel carried out on-site electrical inspection operations in rainy weather, due to the relatively high air humidity, creepage would occur on the operating head directly contacting the high-voltage power supply and the rod of the insulating operating rod on site, and the line The construction personnel will also encounter the following problems during the electrical inspection operation: a. The moist water vapor in the air is easy to condense on the rod body of the insulating rod, and gradually gathers into a water flow to flow down the rod body. When the rod body of the insulating operating rod touches When it reaches the support frame of the high-voltage transmission line, there will be a hidden danger of high-voltage single-phase grounding. b. When the rod body of the insulating operating rod touches the adjacent high-voltage transmission line of another phase, it is very likely that a high-voltage phase-to-phase short circuit will occur. Both of these situations will not only have a serious impact on the normal operation of high-voltage transmission, but also seriously threaten the personal safety of line construction personnel.
