Abstract
The utility model relates to a full insulating metallic oxide lightning arrester. A high voltage line which is elicited from the inner part of the lightning arrester is connected to a phase line which corresponds to a protected device. The utility model is characterized in that the leading wire 2 is a high voltage cable, one end of which is provided with a wire connection nose 1, and the other end of the high voltage cable is sealed in an outer sleeve 3 of the lightning arrester and is connected with a core body 4 of the high voltage cable to form an insulating whole body. The utility model has the advantages that the air distance between adjacent lightning arresters can be zoomed out; the creepage distance of the lightning arrester is increased; the lightning arrester is expanded and used for the zones with high altitude and heavy dirtiness, and therefore, the utility model has flexible and convenient installation and use.
Description
The utility model relates to the overvoltage protection of electric power system electric equipment, is the metal oxide arrester that a kind of high-voltage terminal adopts all insulation structure specifically.
In existing technical scheme, one group of lightning arrester (three) is installed in respectively between A phase line, B phase line, C phase line and the ground wire of protected equipment, therefore, when lightning arrester is installed, must consider phase insulation distance, i.e. air gap.This makes troubles with regard to giving some limited space.
The purpose of this utility model is to overcome shortcoming of the prior art, and a kind of all insulation metal oxide arrester that greatly dwindles alternate air distance, improves the lightning arrester creepage distance is provided.
For achieving the above object, technical solution provided by the utility model is: 2 passed in the lightning arrester overcoat 3 by lead-in wire, be connected in the top electrode 5 in the lightning arrester core body 4 and constitute.It is characterized in that: described lead-in wire 2 is high-tension cable leads, and an end is equipped with wiring nose 1, and the other end is sealed in the lightning arrester overcoat 3 and core body 4 links together, and forms the integral body of all insulation with the overcoat of lightning arrester.
The utlity model has following advantage:
1. when lightning arrester is installed, greatly dwindle alternate air distance, and 2 the wiring nose 1 of will go between is connected on the corresponding phase line of protected equipment, is convenient to assemble.Be particularly useful in the switch cubicle of the confined space.
2. high-tension cable lead-in wire 2 is directly drawn in lightning arrester, be connected to by wiring nose 1 on the corresponding phase line of protected equipment, and the creepage distance of lightning arrester that extended greatly, thus make lightning arrester not be subjected to the restriction in areas such as high height above sea level, heavy pollution.
Fig. 1 is the structural representation of an embodiment of the utility model.
Among the figure: 1 is the wiring nose, and 2 are lead-in wire, and 3 is the lightning arrester overcoat, and 4 is lightning arrester core body, and 5 is the top electrode in the core body.
Below by embodiment, in conjunction with the accompanying drawings the utility model is further described.
Usually; lightning arrester is as the overvoltage protection device of electric power system; generally three-phase (the electric railway system is quarter-phase system) in using; lightning arrester in the existing technology is because high-voltage connection terminal is a metal, and the distance between every adjacent two lightning arresters is different with the difference of electric power system nominal voltage grade.In other words, when using the lightning arrester of existing technology, guarantee alternate air distance.And use the technical program can greatly dwindle alternate air distance, and the wiring nose 1 of its lead-in wire 2 is connected to get final product on the corresponding phase line of protected equipment, convenient, flexibly, be particularly useful in the switch cubicle of the confined space and areas such as high height above sea level, heavy pollution.
Claims (1)
1, a kind of all insulation formula metal oxide arrester; its high-voltage terminal adopts all insulation structure; in lightning arrester, directly draw lead-in wire 2; by wiring nose 1; be connected on the corresponding phase line of protected equipment, it is characterized in that: described lead-in wire 2 is high-tension cable leads, and an end is equipped with wiring nose 1; the other end is connected in core body 4, it is sealed in the overcoat 3 fully and to constitute insulation whole.
