Description

10KV telescopic ground wire installation and hanging device

Technical Field

The utility model relates to the technical field of grounding wire installation and hanging, in particular to a 10kV telescopic grounding wire installation and hanging device.

Background

In the face of social changes of daily and lunar variation, the electric power is continuously increased in the production and life. For the power consumer, every one minute of power failure time increases, the inconvenience and the mental trouble caused by the power failure time will be in a geometric situation. Therefore, in order to increase the power consumption satisfaction and improve the power supply reliability of the power system, the power outage and power transmission work time should be shortened as much as possible. The power interruption and transmission of the power transmission network is not externally embodied, and the power interruption event felt by enterprises and residents is mainly power interruption of the power distribution network of 20kV, 10kV or 0.4kV and the like.

For grounding operation of the power distribution network, portable short-circuit grounding wires are currently commonly used. In use, there are two problems:

1. The device to be grounded is high in position. As described above, the power outage operation of the distribution network device is generally located in two types of scenarios, one: distribution lines of the transformer substation or reactive compensation devices; and II: the user equipment is connected with the user equipment by a station transformer, a ring main unit, a pi-junction box and the like. Some of the above devices are installed on the structure or the tower, and are higher from the ground, for example, the capacitor isolating switch structure in the transformer substation is 3.3m high, and the subscriber station is installed on the tower of about 5 m. Therefore, when the grounding wire is assembled and disassembled, an operator needs to climb the tower or the framework to operate, and the operation belongs to the field of high-altitude operation. Under the conditions of wearing insulating gloves and wearing safety belts, the operation difficulty of assembling and disassembling the grounding wire is high. The time from the beginning of the rod climbing by the unskilled operator is about 30 minutes on average after the ground wire is operated to the lower rod, and the time for the skilled operator to complete the ground wire operation is about 15 minutes. Meanwhile, the high-altitude operation has high physical energy consumption for operators, and high risk of falling and electric shock exists when the ground wire is climbed and assembled and disassembled, and the safety risk is multiplied geometrically when severe and complex meteorological conditions are met.

2. The existing grounding tool is easy to damage. The existing grounding wire conductor end is generally clamped and connected with a brake handle at the lower part of an insulating rod through an epoxy resin pull rod in the insulating rod, and in actual use, the clamp opening of the conductor end is opened for 5 cm at maximum, so that the conductor end cannot be suitable for a wire with special design and cannot be arranged on a multilayer aluminum row with large load. Meanwhile, due to the limitation of the size of the product, the pull rod cannot be safe, firm and heavy, and the material is brittle. In actual use, under the condition of wearing an insulating glove, the condition that the built-in epoxy resin pull rod is broken frequently occurs. This will cause that the conductor end of the ground wire cannot be used normally, and finally the switching operation cannot be completed smoothly.

Therefore, it is necessary to invent a 10kV retractable grounding wire mounting and hanging device to solve the above problems.
