Abstract
The utility model discloses a kind of large capacity drop-type arrester, it is characterized in that: comprise upper bracket, lower carriage, zinc oxide arrester, common zinc oxide lightning arrester and column support type insulator with hot release unit, described upper bracket and lower carriage are all Y-shaped, described zinc oxide arrester, common zinc oxide lightning arrester and the parallel connection of column support type insulator with hot release unit, and be separately fixed between upper bracket and lower carriage.The utility model advantage is compared with prior art: structural design of the present utility model, vent flow while not only having increased overvoltage, and after coming off in the time that zinc oxide arrester runs into overvoltage, another group lightning arrester can also normally be worked, and ensures the normal safe operation of electrical network.
Description
Technical field
The utility model relates to lightning arrester, relates in particular to a kind of large capacity drop-type arrester.
Background technology
The lightning-arrest point of traditional drop type; in the time that circuit suffers overvoltage; zinc oxide arrester meeting is self falling because of the heat of discharge generation; transformer station after coming off; the staff of control centre can't see lightning arrestor movement, once lightning arrester falls, in the time that circuit produces for the second time overvoltage; transmission line is not protected, and is easy to cause lines fault, interruption, damage etc.
Utility model content
The utility model is in order to solve above-mentioned deficiency, and a kind of large capacity drop-type arrester is provided.
Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of large capacity drop-type arrester, it is characterized in that: comprise upper bracket, lower carriage, zinc oxide arrester, common zinc oxide lightning arrester and column support type insulator with hot release unit, described upper bracket and lower carriage are all Y-shaped, described zinc oxide arrester, common zinc oxide lightning arrester and the parallel connection of column support type insulator with hot release unit, and be separately fixed between upper bracket and lower carriage.
Described upper bracket and lower carriage are made by stainless steel.
Operation principle of the present utility model: large capacity drop-type arrester of the present utility model, is mainly used in the lightning protection of urban distribution network 6KV-35KV transmission line.Compare better fail safe with like product, the utility model combines the characteristic of drop-type arrester and common lightning arrester, cleverly two kinds of lightning arresters are fitted together, increase the current by pass of thunder-strike current, in the time of line over-voltage, first the continuous electric current of large power frequency can pass through in the weak spot of lightning arrester, because contain the Gap-Ratios of the point of contact falling not with falling the large of end, serve as electric current and voltage first by falling when end, zinc oxide arrester with falling device can first fall, at this moment, if when circuit produces for the second time overvoltage, another group zinc oxide arrester can normally be worked, ensure that circuit normally moves.Large capacity lightning arrester, combines the feature of common lightning-arrest and drop type, has better protected the normal operation of circuit, has saved operating cost.The place that is particularly suitable for having a power failure is as communication, airport, station, hospital, bustling business district etc.Other performances of product are with distribution type lightning arrester.
The utility model advantage is compared with prior art: structural design of the present utility model, vent flow while not only having increased overvoltage, and after coming off in the time that zinc oxide arrester runs into overvoltage, another group lightning arrester can also normally be worked, and ensures the normal safe operation of electrical network.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is vertical view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of large capacity drop-type arrester, it is characterized in that: comprise upper bracket 1, lower carriage 2, zinc oxide arrester 3, common zinc oxide lightning arrester 4 and column support type insulator 5 with hot release unit, described upper bracket 1 and lower carriage 2 are all Y-shaped, described zinc oxide arrester 3, common zinc oxide lightning arrester 4 and 5 parallel connections of column support type insulator with hot release unit, and be separately fixed between upper bracket 1 and lower carriage 2; Described upper bracket 1 and lower carriage 2 are made by stainless steel.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
