Electric porcelain insulator capable of being quickly connected with cable

Abstract

The invention relates to the technical field of insulators, in particular to an electric porcelain insulator capable of being quickly connected with a cable, which comprises an insulator body. A limiting block is fixedly mounted on the insulator body, a cavity is formed in the limiting block, a square shaft is mounted in the cavity in a sliding manner, and a first spring is fixedly connected to the square shaft. A pressing block and a limiting gear are fixedly installed on the square shaft, a sleeve is fixedly installed in the cavity, a second spring is fixedly installed in the sleeve, a circular shaft is movably connected into the sleeve, a rotary knob and a push rod are fixedly installed on the circular shaft, a gear ring is rotatably installed on the sleeve, and a clamping column is fixedly installed on the gear ring; a through groove is formed in the limiting block; the cable is installed and fixed through the cable clamp installed on the limiting block at the top of the insulatorbody, a small-range fine adjustment mechanism is arranged in the cable clamp, a large-range coarse adjustment mechanism is installed in the limiting block, and the problem that the tension of the cables on the two sides of the cable clamp is not uniform is effectively solved.

Description

technical field [0001] The invention relates to the technical field of insulators, in particular to an electric porcelain insulator capable of quickly connecting cables. Background technique [0002] Porcelain insulators are one of the commonly used insulators. Like insulators made of other materials, they are often used in power transmission lines and electrical equipment to achieve electrical insulation and mechanical fixation, and to increase creepage distances. In the process of erecting high-altitude transmission lines, after the electric porcelain insulators are fixed, the transmission cables are connected. However, the current electric porcelain insulators have the problem of a low success rate of cable connection at one time. Due to the problems of line calculation and cable length measurement It is easy to cause insufficient or excessive tension of the cable after the connection is completed, and it is usually necessary to reconnect the cable or even move the electr...

Problems solved by technology

In the process of erecting high-altitude transmission lines, after the electric porcelain insulators are fixed, the transmission cables are connected. However, the current electric porcelain insulators have the problem of a low success rate of cable connection at one time. Due to the problems of line calculation and cable length measurement It is easy to cause insufficient or excessive tension of the cable after the connection is completed, and it is usually necessary to reconnect the cable or even move the electric porcelain insulator to solve it, which brings more trouble to the originally difficult aerial work , in view of this, we propose an electric porcelain insulator that can quickly connect cables
