Description
Technical field
The utility model relates to electrical network shocking preventing technology field, specifically a kind of suspended-type surge arrester with disconnector.
Background technology
Thunder and lightning is a kind of weather phenomenon that often occurs summer, and the thunder calamity is to natural resources and the human huge threat of environment structure of depending on for existence.At first thunder and lightning produces scorching hot high temperature, also has lightning induction in addition, and lightning induction comprises electrostatic induction and electromagnetic induction, and it can produce the induction high voltage.Thunder and lightning generally is divided into three kinds for the mankind's harm: direct lightning strike, lightning wave are invaded and indirect lightning strike.Direct lightning strike is meant that thunder and lightning directly hits building, trees, the earth, lightning protection device or human body; Lightning wave is invaded and is meant thunder and lightning to overhead transmission line and metal pipe line effect, and lightning wave may be invaded indoor along these pipelines, jeopardizes personal safety or damage equipment; Indirect lightning strike then takes place silently, is difficult for discovering, and consequence is more serious, and direct stroke is different with the object that indirect lightning strike destroys, and direct lightning strike mainly break building, power transmission line on the discharge path hit and extremely wound people and animals etc., and the induction thunder mainly destroys electronic equipment.Thunder and lightning also can cause forest fire, and the annual financial losses that caused are hundreds of millions of.Thunder and lightning can injure human life, and its that powerful electric current can make human heart and respiratory system pause and die.Thunder and lightning also is the one of the main reasons of power breakdown, because its that precipitate powerful electric power can burn transformer.The major function of lightning arrester is the development of restriction lightning overvoltage and switching overvoltage, and the energy that overvoltage produces is released into ground by it, makes power equipment avoid superpotential invasion and attack.Lightning arrester is connected between live wire and the ground usually, and is in parallel with protected equipment.When overvoltage value reached specified action voltage, lightning arrester moved immediately, flow through electric charge, and the over-voltage amplitude is protected apparatus insulated; After magnitude of voltage was normal, lightning arrester restored to the original state rapidly again, to guarantee system's normal power supply.Existing suspended-type surge arrester is not owing to there is release unit, makes it when running into rigor condition such as direct lightning strike, thereby born its blast of super large energy heating causing because of it.
Summary of the invention
The purpose of this utility model is the defective at prior art, provides a kind of space of taking up an area of little, easy for installation and can prevent that lightning arrester is subjected to the suspended-type surge arrester of the band disconnector of thermal explosion.
The purpose of this utility model solves by the following technical programs:
A kind of suspended-type surge arrester with disconnector, comprise lightning arrester body, the upside of lightning arrester body links to each other with earth terminal by gold utensil, be provided with between the gold utensil of lightning arrester body upside and the earth terminal respectively by the gold utensil of bolt and lightning arrester body upside and the suspension plate that earth terminal is fixedly linked, the lower end of described lightning arrester body links to each other by an end of gold utensil and insulator, the other end of insulator links to each other with high-pressure side, the end of the insulator of described high-pressure side inboard is provided with head rod, the other end of head rod successively with disconnector, second connecting rod links to each other with the 3rd connecting rod, and the other end of the 3rd connecting rod links to each other with the insulator of lightning arrester body one side.
Described insulator is horizontally disposed with.
Described second connecting rod and the 3rd connecting rod are movably connected, and the abutting end of second connecting rod and the 3rd connecting rod is provided with the connecting line that links to each other.
Described head rod and the 3rd connecting rod vertically be arranged in parallel.
Described second connecting rod is flat to be provided with.
Described suspension plate is provided with counter.
The utility model has following advantage compared to existing technology:
The utility model is on the basis of suspended-type surge arrester, increased automatic release unit, when rigor condition such as experience direct lightning strike, lightning arrester can in time separate with system, avoid lightning arrester because of bearing the blast that the heating of super large energy causes, guaranteed the safe operation of system; The distinguishing mark that provides simultaneously, the personnel that conveniently patrol and examine in time find and handle.
The utlity model has advantages such as easy for installation, that electrical property is excellent, the occupation of land space is little, suitable promoting the use of.
