Electric porcelain insulator capable of preventing cable from loosening

Abstract

The invention discloses an electric porcelain insulator capable of preventing a cable from loosening. The electric porcelain insulator comprises a main electric porcelain insulator body, a fixing block, a pressing block and an anti-loosening locking mechanism. When the electric porcelain insulator is constructed, the electric porcelain insulator is fixedly connected with a cable; the cable can bewell and quickly connected and fixed through the fixing block and the pressing block, and the fixedly connected cable can be well positioned, locked and locked through the anti-loosening locking mechanism, so the firmness and stability of connection between the cable and the insulator are ensured, and the cable on the insulator is prevented from loosening during use and work; and thus, the normalwork of the insulator is ensured, the power construction quality of the insulator is ensured, and the economic benefit of work is improved.

[0002] An insulator is a device installed between conductors of different potentials or between conductors and ground potential components, which can withstand voltage and mechanical stress; it is a special insulation control that can play an important role in overhead transmission lines; early During the years, insulators were mostly used on utility poles, and gradually developed in the high-voltage wire connection tower. Many disc-shaped insulators are hung on one end of the tower. It is to increase the creepage distance. It is usually made of glass or ceramics, and it is called an insulator; the insulator is not It should fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, otherwise the insulator will not have a significant effect and will damage the service and operating life of the entire line

[0003] When the electric porcelain insulator is connected and fixed with the cable, the cable is usually connected and fixed at both ends of the insulator, and an arc-shaped groove is arranged at the end of the insulator, and the cable is pressed through an arc-shaped plate. After that, it is fixed by screws. Since the screws may loosen during long-term use, the connection between the insulator and the cable will become loose, which will affect the normal operation of the insulator, reduce the quality of the insulator’s electrical construction, and affect the economic benefits of the work. , for this reason, the present invention proposes a kind of electric porcelain insulator that can prevent cable wire from loosening to be used for solving the above-mentioned problem
