Abstract
The invention discloses a novel high-efficient arc-extinguishing lightning arrester disconnector which is connected with a lightning arrester in series. The novel high-efficient arc-extinguishing lightning arrester disconnector comprises a discharging gap, a conductive silicone rubber resistor and a thermal explosion tube, wherein a first end of the conductive silicone rubber resistor is connected with a first electrode of the discharging gap, a second end of the conductive silicone rubber resistor and a second electrode of the discharging gap are connected with a first end of the thermal explosion tube, and the first end of the conductive silicone rubber resistor and a second end of the thermal explosion tube serve as two connection ends of the disconnector. The conductive silicone rubber resistor is connected to the discharging gap in parallel, thereby forming not only a current leakage passage of the lightning arrester but also a heating source of action under low-power frequency failure current of the disconnector, so that the disconnector is reasonable in structure, reliable to operate, adaptive to not only the characteristics of a power grid in China, but also a failure damage mechanism of the lightning arrester, and particularly applicable to the power grid in China.
Description
Technical field
The present invention relates to a kind of separator for lightning arrester, particularly relate to a kind of Novel lightning arrester disconnector of efficient arc extinguishing.
Background technology
Disconnector is as the auxiliary products of lightning arrester, connect with lightning arrester and use, can action depart from when surge arrester failure damages, lightning arrester fault damaged in time and isolation of system provide clear sign, thus guarantee the normal operation of system, and facilitate searching and the examine and replace of lightning arrester of fault point.
All oneself generally supports the use disconnector for distribution type, power station type and the Transmission Line Arrestor run in the countries and regions electrical networks such as America and Europe, Japan and Southeast Asia, and at China, only has minority area to use at present, and multiplex distribution type lightning arrester.The reason of this phenomenon is caused to have two: one to be the performance of existing disconnector and act on also for customer acceptance is with familiar, another be existing disconnector the reasonability of structural principle, reliability of operation, with the applicability of China Power Grids feature and with the equal Shortcomings of all many-sides and the defect such as the matching of surge arrester failure damage mechanism, the requirement of use can not be met.
Summary of the invention
Object of the present invention is just to provide to solve the problem a kind of Novel lightning arrester disconnector of the efficient arc extinguishing adapted with China Power Grids feature.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The Novel lightning arrester disconnector of efficient arc extinguishing of the present invention, be connected in series with lightning arrester, comprise discharging gap, conductive silicon rubber resistance and thermal explosion pipe, the first end of described conductive silicon rubber resistance and the first Electrode connection of described discharging gap, second end of described conductive silicon rubber resistance, the second electrode of described discharging gap are connected with the first end of described thermal explosion pipe, and the first end of described conductive silicon rubber resistance and the second end of described thermal explosion pipe are respectively two links of described disconnector.
As preferably, described conductive silicon rubber resistance is ring-shaped resistor, and the first electrode of described discharging gap is connected with two end faces of described conductive silicon rubber resistance respectively with the second electrode.
Beneficial effect of the present invention is:
The present invention adopts conductive silicon rubber resistor coupled in parallel on discharging gap, it is the leakage current passage of lightning arrester, it is again the pyrotoxin of action under the little power frequency fault current of disconnector, thus disconnector can be made rational in infrastructure, reliable, both adapted with the feature of China Power Grids, and matched with the fault damage mechanism of lightning arrester again, be particularly useful for China Power Grids.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, the Novel lightning arrester disconnector of efficient arc extinguishing of the present invention, be connected in series with lightning arrester, comprise discharging gap 2, conductive silicon rubber resistance 3 and thermal explosion pipe 4, the first end of conductive silicon rubber resistance 3 and the first Electrode connection of discharging gap 2, second end of conductive silicon rubber resistance 3, the second electrode of discharging gap 2 are connected with the first end of thermal explosion pipe 4, and the first end of conductive silicon rubber resistance 3 and the second end of thermal explosion pipe 4 are respectively two links 1 of described disconnector.For making disconnector volume miniaturized, conductive silicon rubber resistance 3 is ring-shaped resistor, and the first electrode of discharging gap 2 is connected with two end faces of conductive silicon rubber resistance 3 respectively with the second electrode.
Arc energy after the distance value of discharging gap 2 discharging gap punctures to discharging gap 2 is directly proportional, for the resistance characteristics of disconnector, the distance value of discharging gap 2 wants less good, and the operating characteristics for disconnector, then wish that the distance value of discharging gap 2 is larger good.The distance value of discharging gap 2 generally gets 0.5 1 3nm, after the distance value determining discharging gap 2, regulate and control the amount of heat transfer between the second electrode of discharging gap 2 and thermal explosion pipe 4 by structural design, thus realize the unification between disconnector resistance characteristics and operating characteristics.
Composition graphs 1, disconnector of the present invention adapts to 10kV, 35kV, 110kV, 220kV electric pressure lightning arrester, and is applicable to power station type and Transmission Line Arrestor.Disconnector and lightning arrester are connected in series during use, should make disconnector energy free action during installation and form enough discharging gaps 2, the lightning arrester damaged to make fault and system can reliably be isolated, thus guarantee the normal operation of not influential system.
As shown in Figure 2, there is shown a kind of traditional separator for lightning arrester, comprise two links 1, discharging gap 2, thermal explosion pipe 4 and electric capacity 5, discharging gap 2 and thermal explosion pipe 4 are connected in series formation series circuit, and electric capacity 5 and series circuit are connected in parallel.Roll-off characteristic in this disconnector and metal oxide arrester fault damage mechanism does not match, and incompatible with the feature of China Power Grids, so be difficult to promote in China.
As shown in Figure 3, there is shown another kind of traditional separator for lightning arrester, comprise two links 1, metal oxide resistance 6 and preloading spring 8, linked together by scolding tin 7 between metal oxide resistance 6 and preloading spring 8.This disconnector utilizes metal oxide resistance 6 to make pyrotoxin, can realize the successful action under little power frequency fault current, thus adapts with the feature of system with non effectively earth ed neutral; But under large power frequency fault current, because metal oxide resistance 6 generates heat to melting, scolding tin 7 is temperature required needs certain hour, the requirement of rapid action can not be realized, so incompatible with the feature of system with effectively earthed neutral, do not match with the catastrophe characteristics in metal oxide arrester fault damage mechanism, be also difficult to apply.
