Crimping type 10kV strain clamp used for hot-line work of insulating bar method

Abstract

The invention discloses a crimping type 10kV strain clamp used for hot-line work of an insulating bar method. The strain clamp comprises an integrated crimping type 10kV strain clamp (5) provided with a cantilever type guide bar (4) at the bottom and a lead fixing device which can be inserted into the guide bar (4), wherein the lead fixing device comprises a tubular guide bar fixing wire clamp (7), an arc groove shaped guide bar fixing plate (1) which is arranged in the guide bar fixing wire clamp and is provided with an upward notch, a fastening bolt (2) which is upwards screwed into the interior from the exterior of the bottom of the guide bar fixing wire clamp to support a guide bar fixing plate of a branch wire and a lead crimping tube (3) connected to the outer end of the guide bar fixing wire clamp. The strain clamp is easy to fix the branch wire and a trunk line, safe, reliable, time-saving and labor-saving.

Description

technical field [0001] The invention belongs to the technical field of electric fittings. Background technique [0002] At present, the domestic 10kV distribution network live operation has been vigorously developed, and the operation technology is becoming more and more mature. In the work of lapping the drain wire in live work, there are currently two commonly used methods in China, namely the insulating glove method and the insulating operating rod method. The insulating glove operation method manually fixes the branch line and the main line with binding wires (clamps), and the human body is directly exposed to the high-voltage electric field during operation, which poses a great potential safety hazard. The insulated operating rod operation method is that the human body contacts the charged body through the operating rod, and always maintains a certain safe distance from the charged body. Compared with the insulating glove operation method, it is safer. Insulated opera...

Problems solved by technology

The insulating glove operation method manually fixes the branch line and the main line with binding wires (clamps), and the human body is directly exposed to the high-voltage electric field during operation, which poses a great safety hazard

The insulated operating rod operation method is that the human body contacts the charged body through the operating rod, and always maintains a certain safe distance from the charged body. Compared with the insulating glove operation method, it is safer. Insulated operating rods replace manual wire binding (fixed by wire clips), and binding (fixing) is more difficult. It takes about 2 hours for skilled workers to complete the three 10kV wire laps. The labor intensity is high and the work efficiency is low. Therefore, the insulating operating rod Few people use the operation method of lapping and draining lines
