High-voltage fuse for power transmission and transformation in oil field

Abstract

The invention discloses a high-voltage fuse for power transmission and transformation in an oil field, and the fuse comprises an insulator magnetic bottle, two ends of the insulator magnetic bottle are fixedly connected with connecting rings, the bottom of one connecting ring is fixedly connected with an upper conductive connecting piece, one side of the upper conductive connecting piece is fixedly connected with an upper binding post. An upper static contact plate is fixedly connected to the center of the bottom of the upper conductive connecting piece, an upper contact groove is formed in the middle of the upper static contact plate, and side plates are fixedly connected to the two sides of the bottom of the upper conductive connecting piece. According to the high-voltage fuse for power transmission and transformation in the oil field provided by the invention, when the fuse tube is replaced, the fuse tube is guided and limited to move and transfer, so that the fuse wire can be replaced without disassembling the whole fuse, and the stability and the accuracy during replacement and installation are improved; and the fusing trigger sensitivity and safety are good.

Description

technical field [0001] The invention relates to a fuse, in particular to a high-voltage fuse used for power transmission and transformation in oil fields. Background technique [0002] The high-voltage fuse is the simplest short-circuit protection device, and the fuse tube is filled with fine quartz sand for arc extinguishing. The fuse is a metal wire or sheet made of a metal material with a low melting point, which is connected in series in the circuit to be protected. When the circuit or equipment in the circuit is overloaded or fails, the high-voltage fuse fuse will heat up and melt, thereby cutting off the fuse. circuit, breaking current, to achieve the purpose of protecting the circuit or equipment. [0003] High-voltage fuses are widely used in high-voltage and low-voltage power distribution systems, control systems, and electrical equipment. As short-circuit and over-current protectors, they are one of the most commonly used protection devices. [0004] Existing hig...

AI Technical Summary

Problems solved by technology

[0004] Existing high-voltage fuses often need to be dismantled as a whole after blowing to complete the installation and replacement of the fuse. The speed is slow and the work efficiency is low; The conductive work in the environment causes the memory of the high-voltage fuse to be corroded, which reduces the working life of the fuse; at the same time, the trigger sensitivity of the existing high-voltage fuse is insufficient, which affects the safety of use
