Abstract
The invention discloses a hot-melting lightning arrester disconnecting mechanism, comprising a high-voltage end connection plate and a low-voltage end connection plate, wherein an insulator and a lightning arrester are fixed between the high-voltage end connection plate and the low-voltage end connection plate; the top of the lightning arrester is electrically connected with the high-voltage end connection plate through an insertion mechanism; the lower end of the lightning arrester is fixedly and electrically connected with a low-melting alloy base plate which is arranged on the low-voltage end connection plate, and the low-melting alloy base plate is fixed on the low-voltage end connection plate through bolts; the insertion mechanism comprises a plug bush and a spring, the plug bush and the spring are fixed on the high-voltage end connection plate, a plug is arranged at the upper end of the lightning arrester, a concave ring is arranged at the lower end of the plug, the plug is inserted in the plug bush, and the concave ring corresponds to the spring and compresses the spring. The hot-melting lightning arrester disconnecting mechanism has the advantages that an easy-melting alloy base plate is utilized; when the base plate is shocked by high voltage, the easy-smelting alloy heats and is smelted, and the lightning arrester is not supported so as to naturally fall down; therefore, the permanent ground connection accident is prevented from occurring.
Description
Technical field
The present invention relates to lightning arrester, is a kind of hot melt lightning arrester specifically.
Background technology
Overvoltage protection in electric power system requires more and more higher, because of lightning arrester quality and defencive function poor, often there is the accident of power outage and damage power transmission and transforming equipment in electric power system; Because damaging and the dismounting that will have a power failure appears in lightning arrester regular maintenance and lightning arrester, cause many losses; Most lightning arrester do not have release unit or release unit inoperative, the power-off fault loss therefore caused is also a lot.So how lightning arrester when strong lightning current, switching overvoltage electric current or can not affect the normal power supply of supply line when self damages, it is the problem that a lot of experts and scholars and lightning arrester producer drop into that substantial contribution and time goes to study.
At present, at home and abroad lightning arrester all devises a kind of release unit, to be located in lightning arrester or to connect with lightning arrester to use, and solves the problem that lightning arrester sets off an explosion because not departing from electric power system or electric power system permanent earth occurs.Wherein the function of release unit should meet when lightning arrester is by normal lightning current or switching overvoltage electric current, and release unit does not answer action; And when lightning arrester is aging die of old age or damage because of certain factor generation internal flashover time, should want can action message, in case comminuted blast occurs lightning arrester or cause the accident of electric power system permanent earth to occur.Release unit is of a great variety, total be divided into heat explosion type, fuse wire type and hot melten type three major types, each have their own pluses and minuses of these devices.Chinese Patent Application No. 03111237.4 discloses a kind of hanging anti-theft lightning arresters, and the drawback of this patent is that its release unit adopts mechanical operation, easily produces permanent earth accident.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of lightning arrester adopting fusible alloy technology, concrete technical scheme is as follows:
A kind of hot melt lightning arrester releasing mechanism, comprises high-pressure side connecting plate, low-pressure end connecting plate, and between described high-pressure side connecting plate, low-pressure end connecting plate, fixed insulation, is also fixed with lightning arrester between described high-pressure side connecting plate, low-pressure end connecting plate; The top of described lightning arrester is electrically connected with high-pressure side connecting plate by plug-in connection; Described lightning arrester lower end fix with the acolite backing plate be arranged on low-pressure end connecting plate and ensure to be electrically connected, described acolite backing plate is fixedly bolted on low-pressure end connecting plate; Described plug-in connection comprises and is fixed on sleeve on high-pressure side connecting plate and spring, and the upper end of described lightning arrester arranges plug, and described plug lower end arranges scrobicular ring, and described plug inserts in sleeve, and described scrobicular ring is corresponding with spring and by spring-compressed.
Described acolite backing plate is oval, and its minor axis length is greater than the diameter of end connector under lightning arrester.
Described acolite backing material is bismuth tin acolite, and its melting temperature is 150 DEG C.
Advantage of the present invention is: the backing plate adopting fusible alloy, and when being subject to impacting with high pressure, zinc oxide arrester has larger electric current to pass through, and fusible alloy is exothermic melting, and lightning arrester does not support, and naturally falls, prevents the generation of permanent earth accident.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
The present invention is illustrated below in conjunction with accompanying drawing, as shown in Figure 1, the present invention includes high-pressure side connecting plate 3, low-pressure end connecting plate 4, described high-pressure side connecting plate 3, low-pressure end connecting plate 4 fixed insulation 2, also be fixed with lightning arrester 6 between described high-pressure side connecting plate 3, low-pressure end connecting plate 4, described lightning arrester 6 is zinc oxide arrester; The top of described lightning arrester 6 is electrically connected with high-pressure side connecting plate 3 by plug-in connection; Described lightning arrester 6 lower end fix with the acolite backing plate 5 be arranged on low-pressure end connecting plate 4 and ensure to be electrically connected, described acolite backing plate 5 is fixedly bolted on low-pressure end connecting plate 4; Described plug-in connection comprises and is fixed on sleeve 9 on high-pressure side connecting plate and spring 8, the upper end of described lightning arrester arranges plug 10, described plug 10 lower end arranges scrobicular ring 7, and described plug 10 inserts in sleeve 9, and described scrobicular ring 10 is corresponding with spring 8 and compressed by spring 8.Described high-pressure side connecting plate 3 arranges cable joint 1.
For ensureing that acolite backing plate 5 melts rear lightning arrester, described acolite backing plate be ellipse, and its minor axis length is greater than the diameter of end connector under lightning arrester.
Described acolite backing material is bismuth tin acolite, and its melting temperature is 150 DEG C.Also can reset temperature according to the loaded current of design; Acolite backing material can adopt Dongguan Wo Chang nonferrous materials factory product.
Principle of the present invention is: when circuit is subject to impacting with high pressure, zinc oxide arrester produces action, simultaneously, acolite backing material is subject to also producing heat when larger current is impacted, and after the fusing of acolite backing material, lightning arrester does not support, under the elastic force effect of gravity and lightning arrester top spring, lightning arrester falls, and therefore, can avoid the generation that permanent earth accident occurs.
