Abstract

The utility model relates to an arrester technical field specifically discloses a directional disconnect -type metal oxide lightning arrester is exploded to heat, the power distribution box comprises a box body, a plurality of zinc oxide varistors are equipped with in the box, du lidun is installed on the box top, dulidun and lie in the zinc oxide varistors of the top between be equipped with the spring, the zinc oxide varistors's of below below is equipped with the cushion lieing in, and the cushion below is equipped with a heat and explodes the warhead, the bottom of box is equipped with hot exploding and breaks away from the end cover, the box is equipped with silicon rubber covered outward. The utility model has the advantages that, this arrester has quick action and directional characteristic of separating, can endure the ability of regulation current rush and action load again, the heat energy that produces after exceeding specified pressure release and current -carrying, and in the inside formation hot pressing of arrester, the warhead is exploded to ignition heat makes the arrester rear end separate to appointed orientation, rapid deenergization, the arrester withdraws from the operation, and the avoid accident further enlarges.

Description

A kind of thermal explosion directional separation formula metal oxide arrester
Technical field
The utility model relates to arrester technical field, particularly relates to a kind of thermal explosion directional separation formula burning Thing arrester.
Background technology
The magnetosheath of arrester tubulose is generally equipped with carborundum or zinc oxide valve plate, when properly functioning, these Valve block has the highest resistance, when transmission line of electricity is struck by lightning, fast at the effect lower disc resistance of thunder and lightning high pressure Speed declines, and the electric charge of thunder and lightning i.e. enters ground by arrester so that it is its electrical equipment exempts from destruction.After thunder and lightning, valve The resistance of sheet recovers automatically.This arrester is at running, when producing fault, arrester internal temperature Can steeply rise, it is possible to produce blast.
Utility model content
The purpose of this utility model is to provide a kind of thermal explosion directional separation formula metal oxide arrester, and this is taken shelter from the thunder Utensil has the characteristic of quick acting and directional separation, is resistant to again rated current impact and the ability of operating duty.
To achieve these goals, the utility model have employed following technical scheme: a kind of thermal explosion orientation is divided From formula metal oxide arrester, including casing, described casing is built with multiple zinc oxide resistance sheets；
Described casing top is installed Du Lidun, Du Lidun and is provided with between the zinc oxide resistance sheet of the top Spring；
It is provided with cushion block in the lower section of the zinc oxide resistance sheet being positioned at bottom, below cushion block, is provided with a thermal explosion bullet；
The bottom of described casing is provided with thermal explosion and departs from end cap.
Wherein, described casing is externally provided with silastic material.
The beneficial effects of the utility model are: this arrester has the characteristic of quick acting and directional separation, It is resistant to again rated current impact and the ability of operating duty, the heat produced after beyond specified pressure release and current-carrying Can, it is internally formed hot pressing at arrester, ignites thermal explosion bullet and make arrester rear end separate to assigned direction, fast Quick-break switch power supply, arrester is out of service, and Accident prevention expands further.
Accompanying drawing explanation
In order to be illustrated more clearly that the utility model embodiment technical scheme, institute in embodiment being described below The accompanying drawing used is needed to be briefly described, it should be apparent that, the accompanying drawing in describing below is only this practicality Novel in order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below by p- In embodiment or description of the prior art, the required accompanying drawing used is briefly described, skill common for this area From the point of view of art personnel, on the premise of not paying creative work, it is also possible to obtain other according to these accompanying drawings Accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, to the technical side in the utility model embodiment Case is clearly and completely described, it is clear that described embodiment is only that the utility model part is real Execute example rather than whole embodiments.Based on the embodiment in the utility model, ordinary skill people The every other embodiment that member is obtained under not making creative work premise, broadly falls into the utility model The scope of protection.
A kind of thermal explosion directional separation formula metal oxide arrester as shown in Figure 1, including casing, described case Internal equipped with multiple zinc oxide resistance sheets 3；Described casing top is installed Du Lidun 1, Du Lidun 1 and is positioned at It is provided with spring 2 between the zinc oxide resistance sheet 3 of top；Lower section at the zinc oxide resistance sheet 3 being positioned at bottom It is provided with cushion block 4, below cushion block 4, is provided with a thermal explosion bullet 5；The bottom of described casing is provided with thermal explosion and departs from end cap 6。
The heat energy produced after beyond specified pressure release and current-carrying, is internally formed hot pressing at arrester, ignites thermal explosion Bullet 5 makes arrester rear end separate to assigned direction, and rapid deenergization, arrester is out of service, prevents Accident expands further.
The utility model solves arrester and fires problem on fire in casing, does not results in secondary in casing Destroy；Using Du Lidun 1 to encapsulate arrester zinc oxide resistance sheet 3, good insulation preformance, tolerance intensity is big；Adopt With silicon rubber, core body is encapsulated, improve arrester and seal and humidity resistance；Arrester and plug-in unit are formed soft Property docking, coordinate closely, be effectively reduced shelf depreciation and the not enough problem of creep distance, make interpolation arrester There is higher serviceability and security.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all Within protection domain of the present utility model should be included in.
