Abstract
Description
Technical Field
[0001] This utility model relates to the field of power transmission line technology, specifically to a crossarm for tower-connecting support of power transmission lines. Background Technology
[0002] Transmission lines are constructed by using transformers to step up the voltage of electrical energy generated by generators, and then connecting it to the transmission line via control equipment such as circuit breakers. Structurally, transmission lines are divided into overhead transmission lines and cable lines. Overhead transmission lines consist of line towers, conductors, insulators, line hardware, guy wires, tower foundations, grounding devices, etc., and are erected on the ground. According to the nature of the current transmitted, power transmission is divided into AC transmission and DC transmission.
[0003] Existing technology publication CN214899820U discloses an insulating support crossarm for bypass operations. This crossarm can be used with bypass operation equipment. The crossarm body is composed of multiple insulating sleeves, and its overall telescopic length can be adjusted as needed to adapt to the on-site operation requirements of different areas. The inner wall of each insulating sleeve has a positioning protrusion. After two adjacent insulating sleeves are inserted and fitted, the positioning protrusion engages with a positioning groove. The positioning mechanism includes a positioning screw arranged radially along a fixed ring and screwed to the fixed ring. The end of the positioning screw has a locking part that abuts against the positioning groove of the insulating sleeve. One end of one insulating sleeve located at both ends of the crossarm body is fitted with an insulating protective cover, and the other end of the insulating sleeve has a rotating mounting part with a pivot hole. The outer periphery of one end of the tube corresponding to the rotating mounting part is provided with a gripping part, the surface of which is treated with anti-slip material. The outer periphery of the end of the insulating sleeve that is inserted into another insulating sleeve is provided with an anti-detachment protrusion. When bypassing the work, the operator can place this device on the work platform. During use, the overall telescopic length can be adjusted as needed to adapt to the on-site work requirements of different areas. After the overall length of the crossarm body is set, the insulating sleeve is fixed by a positioning mechanism, thereby improving the stability and firmness of the crossarm body. In addition, the bypass cable can be fixed by a cable fixing clamp. Since the cable fixing clamp is rotatably mounted on the fixing ring, the cable guidance arrangement for bypassing the work is more flexible, thereby simplifying the workload of bypassing the work, reducing the working time of bypassing the work, and improving work efficiency; it has high practical value.
[0004] However, due to the poor adjustability and installation capability of the bypass operation insulation support crossarm in the existing technology CN214899820U patent, it is impossible to install the tower-type support crossarm in the appropriate position as needed during the actual use of the bypass operation insulation support crossarm. This makes it inconvenient to adjust the insulation support crossarm to the appropriate position and angle, thus affecting the support effect of the bypass operation insulation support crossarm.
