Description
Technical field
The utility model relates to a kind of separator for lightning arrester, relates in particular to a kind of Novel lightning arrester disconnector of efficient arc extinguishing.
Background technology
Disconnector is as the auxiliary products of lightning arrester, the use of connecting with lightning arrester, when damaging, surge arrester failure can move disengaging, the lightning arrester that fault is damaged in time and isolation of system and provide clear sign, thereby guarantee the normal operation of system, and facilitate fault point search and the maintenance of lightning arrester is changed.
All oneself generally supports the use disconnector to distribution type, power station type and the Transmission Line Arrestor of moving in the countries and regions electrical networks such as America and Europe, Japan and Southeast Asia, and, at China, only has at present the minority area to use, and multiplex distribution type lightning arrester.Cause the reason of this phenomenon to have two: one is that performance and the effect that has disconnector now also is not customer acceptance and familiar, another be existing disconnector the reasonability of structural principle, reliability of operation, with the applicability of China Power Grids characteristics and with the equal Shortcomings of all many-sides and the defects such as matching of surge arrester failure damage mechanism, can not meet the requirement of use.
The utility model content
The purpose of this utility model provides Novel lightning arrester disconnector a kind of and the efficient arc extinguishing that the China Power Grids characteristics adapt with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The Novel lightning arrester disconnector of efficient arc extinguishing described in the utility model, 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 is connected with the first electrode of described discharging gap, the second electrode of the second end of described conductive silicon rubber resistance, described discharging gap be connected the first end of thermal explosion pipe and connect, the second end of the first end of described conductive silicon rubber resistance and described thermal explosion pipe is respectively two links of described disconnector.
As preferably, described conductive silicon rubber resistance is ring-shaped resistor, the first electrode of described discharging gap be connected electrode and be connected with two end faces of described conductive silicon rubber resistance respectively.
The beneficial effects of the utility model are:
The utility model adopts conductive silicon rubber resistance to be connected in parallel on discharging gap, it is the leakage current passage of lightning arrester, it is again the pyrotoxin that moves under disconnector unskilled labourer frequency fault current, thereby can make disconnector rational in infrastructure, reliable, both with the characteristics of China Power Grids, adapted, be complementary with the fault damage mechanism of lightning arrester again, be particularly useful for China Power Grids.
Description of drawings
Fig. 1 is the electrical block diagram of the Novel lightning arrester disconnector of efficient arc extinguishing described in the utility model;
Fig. 2 is one of electrical block diagram of traditional separator for lightning arrester;
Fig. 3 be traditional separator for lightning arrester electrical block diagram two.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the Novel lightning arrester disconnector of efficient arc extinguishing described in the utility model, 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 is connected with the first electrode of discharging gap 2, the first end that the second end of conductive silicon rubber resistance 3, the second electrode of discharging gap 2 are connected with the thermal explosion pipe connects, and the second end of the first end of conductive silicon rubber resistance 3 and thermal explosion pipe 4 is respectively two links 1 of described disconnector.For making the miniaturization of disconnector volume, conductive silicon rubber resistance 3 is ring-shaped resistor, the first electrode of discharging gap 2 be connected electrode and be connected with two end faces of conductive silicon rubber resistance 3 respectively.
The distance value of discharging gap 2 discharging gaps is directly proportional to the arc energy after discharging gap 2 punctures, resistance characteristics for disconnector, it is less good that the distance value of discharging gap 2 is wanted, and, for the operating characteristics of disconnector, wish that the distance value of discharging gap 2 is good greatly a bit.The distance value of discharging gap 2 is generally got 0.5 1 3nm, after the distance value of determining discharging gap 2, can regulate and control the second electrode of discharging gap 2 and the amount of heat transfer between thermal explosion pipe 4 by structural design, thereby realize the unification between disconnector resistance characteristics and operating characteristics.
In conjunction with Fig. 1, disconnector described in the utility model adapts to 10kV, 35kV, 110kV, 220kV electric pressure lightning arrester, and is applicable to power station type and Transmission Line Arrestor.During use, disconnector and lightning arrester are connected in series, should make disconnector can freely move and form enough discharging gaps 2 during installation, so that lightning arrester and system that fault is damaged can reliably isolate, thereby guarantee the normal operation of the system that do not affect.
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 the formation series circuit, and electric capacity 5 is connected in parallel with series circuit.Roll-off characteristic in this disconnector and metal oxide arrester fault damage mechanism is not complementary, and incompatible with the characteristics 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, link 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 unskilled labourer's frequency fault current, thereby with the characteristics of system with non effectively earth ed neutral, adapt; But under large power frequency fault current, because metal oxide resistance 6 generates heat to melting the temperature required certain hour that needs of scolding tin 7, can not realize the requirement of action rapidly, so incompatible with the characteristics of system with effectively earthed neutral, be not complementary with the catastrophe characteristics in metal oxide arrester fault damage mechanism, be difficult to apply yet.
