10kV distribution network ground potential live-line disassembly and assembly lead shielding tool

Abstract

The invention discloses a 10kV distribution network ground potential live-line disassembly and assembly lead shielding tool, which relates to the field of power and electricity and mainly comprises asupporting framework A and a supporting framework B. The supporting framework A is of a frame structure with two through ends and a notch formed in one side. A shielding plate is hinged between the notch position of the supporting framework A and the supporting framework B, and a handle B is arranged on the shielding plate and can shield a gap formed between one side of the supporting framework Aand one side of the supporting framework B; and when the shielding plate rotates to a position where the handle A and the handle B are bonded with each other, the cable can enter the gap and is clamped on the clamping groove framework. The tool has the beneficial effects that the operation efficiency can be effectively improved, and the number of operators and the operation time are reduced; the insulation distance is enough, operation is convenient, safe and easy, and the construction process is reliable; the operation equipment lapped by using the method is convenient to disassemble in a live-line manner, and can operate without power failure; only 2-3 persons are needed for operation, and operation can be conducted in places such as mountainous regions where transportation is inconvenient and the places are limited.

Description

technical field [0001] The invention relates to the field of electric power, and mainly relates to a 10kV distribution network ground potential charged disconnecting wire shielding tool. Background technique [0002] At present, live working is more and more widely recognized by all walks of life. The live operation of 10kV distribution network can make customers feel the convenience brought by live operation more intuitively, so its development speed is also changing with each passing day. At present, in the live work of distribution lines, the working methods mainly include insulating rod working method and insulating glove working method. In the industry, the insulating pole operation method is called the indirect operation method, and the insulating glove operation method is called the direct operation method. [0003] There are following defects in prior art scheme: [0004] 1. With the increase of the use time of power distribution lines, the line loss rate continue...

AI Technical Summary

Problems solved by technology

[0004] 1. With the increase of the use time of power distribution lines, the line loss rate continues to increase. At the same time, various faults will occur during daily operation and use. Once the power distribution personnel operate improperly, it is easy to cause electric shock hazards, and the consequences are unimaginable. ;

[0005] 2. From the beginning of inserting the wire clamp to the tightening of the wire clamp bolt, the operator on the pole needs to keep looking up and maintain the upward movement of the arm, which consumes a lot of physical energy. If it takes more than 2 minutes, visual fatigue and arm numbness and swelling will occur. The feeling of pain, shortness of breath, there is a certain potential safety hazard;

[0006] 3. When the operator on the pole inserts the wire clamp into the main wire through the insulating clamp rod, the angle is not easy to grasp. A little carelessness touches the pressure plate and it will be skewed, and the wire is blocked so that the wire clamp cannot be embedded in place. At this time It is necessary to retract and readjust the angle of the pressure plate to continue to try the scarfing operation, which is time-consuming and laborious;

[0007] 4. When dealing with the end of the drainage wire, if the treatment is not smooth or the bending direction is not suitable, the end of the drainage wire will be loose or cannot be inserted during the process of using the insulating lock rod to insert the end of the drainage wire into the clamp, and it needs to be repeated. It needs to be retracted and readjusted to penetrate into place, which requires extremely high endurance and skill of the operator on the pole, which seriously affects the working efficiency
