Abstract
The present invention discloses a kind of hot melt arrester releasing mechanism, including high-pressure side connecting plate, low-pressure end connecting plate, and fixed insulation, is further fixed on arrester between the high-pressure side connecting plate, low-pressure end connecting plate；The top of the arrester is electrically connected by plug-in connection with high-pressure side connecting plate；The lower end of the arrester is fixed with the acolite backing plate being arranged on low-pressure end connecting plate and ensures to electrically connect, and the acolite backing plate is fixed and is bolted on low-pressure end connecting plate；The plug-in connection includes being fixed on sleeve and spring on high-pressure side connecting plate, and the upper end of the arrester sets plug, and the plug lower end is set in scrobicular ring, the plug insertion sleeve, and the scrobicular ring is corresponding with spring and by spring-compressed.It is an advantage of the invention that：Using the backing plate of fusible alloy, when by impacting with high pressure, fusible alloy is exothermic melting, and arrester is not supported, and falls naturally, it is therefore prevented that the generation of permanent earth accident.
Description
Technical field
The present invention relates to arrester, specifically a kind of hot melt arrester.
Background technology
Overvoltage protection in power system requires more and more higher, because arrester quality and defencive function are poor, electric power
Often occur power outage in system and damage the accident of power transmission and transforming equipment；Because arrester regular maintenance and arrester go out
Now damage and the dismounting that to have a power failure, cause many losses；Most arresters are not acted as without departing from device or release unit
With, therefore the power-off fault loss caused is also a lot.So, how arrester can be in strong lightning current, switching overvoltage electricity
The normal power supply of supply line is not influenceed in the case of stream or in the case that itself is damaged, and is many experts and scholars and arrester factory
Family's input substantial contribution goes the problem of research with the time.
At present, at home and abroad arrester all devises a kind of release unit, be located in arrester or with arrester string
Connection is used, solve arrester because can not depart from power system set off an explosion or occur power system permanent earth the problem of.Its
The function of middle release unit should be met when arrester is by normal lightning current or switching overvoltage electric current, and release unit should not
Action；And when arrester aging die of old age or because certain factor occur internal flashover damage when, should want can action message, to forfend
Thunder device occurs comminuted blast or causes the accident of power system permanent earth to occur.Release unit species is various, and total can
It is divided into heat explosion type, fuse wire type and hot melten type three major types, each have their own advantage and disadvantage of these devices.Chinese Patent Application No.
03111237.4 discloses a kind of hanging anti-theft lightning arresters, is that its release unit uses mechanical operation the drawbacks of the patent,
It is also easy to produce permanent earth accident.
The content of the invention
In order to solve the above technical problems, it is an object of the invention to provide a kind of arrester of use fusible alloy technology, tool
Body technique scheme is as follows：
One kind hot melt arrester releasing mechanism, including high-pressure side connecting plate, low-pressure end connecting plate, the high-pressure side connection
Fixed insulation, arrester is further fixed between the high-pressure side connecting plate, low-pressure end connecting plate between plate, low-pressure end connecting plate；Institute
The top for stating arrester is electrically connected by plug-in connection with high-pressure side connecting plate；The lower end of the arrester is with being arranged on low-pressure end
Acolite backing plate on connecting plate is fixed and ensures electrical connection, and the acolite backing plate is fixed and is bolted on low pressure
Hold on connecting plate；The plug-in connection includes the sleeve and spring being fixed on high-pressure side connecting plate, the upper end of the arrester
Plug is set, and the plug lower end is set in scrobicular ring, the plug insertion sleeve, the scrobicular ring is corresponding with spring and by spring pressure
Contracting.
The acolite backing plate is ellipse, and its minor axis length is more than the diameter of end connector under arrester.
The acolite backing material is bismuth tin acolite, and its melting temperature is 150 DEG C.
It is an advantage of the invention that：Using the backing plate of fusible alloy, when by impacting with high pressure, Zinc-Oxide Arrester has larger
Electric current pass through, fusible alloy is exothermic melting, and arrester is not supported, naturally fall, it is therefore prevented that the hair of permanent earth accident
It is raw.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
The present invention is illustrated below in conjunction with the accompanying drawings, is connected as shown in figure 1, the present invention includes high-pressure side connecting plate 3, low-pressure end
Fishplate bar 4, the high-pressure side connecting plate 3,4 fixed insulation 2 of low-pressure end connecting plate, the high-pressure side connecting plate 3, low-pressure end connect
Arrester 6 is further fixed between fishplate bar 4, the arrester 6 is Zinc-Oxide Arrester；The top of the arrester 6 passes through grafting machine
Structure is electrically connected with high-pressure side connecting plate 3；The lower end of the arrester 6 and the acolite pad being arranged on low-pressure end connecting plate 4
Plate 5 is fixed and ensures electrical connection, and the acolite backing plate 5 is fixed and is bolted on low-pressure end connecting plate 4；It is described to insert
Connection mechanism includes the sleeve 9 and spring 8 being fixed on high-pressure side connecting plate, and the upper end of the arrester sets plug 10, described
The lower end of plug 10 is set in scrobicular ring 7, the insertion of plug 10 sleeve 9, and the scrobicular ring 7 is corresponding with spring 8 and compresses spring 8.
The high-pressure side connecting plate 3 sets cable connector 1.
To ensure that arrester sinks after the fusing of acolite backing plate 5, the acolite backing plate is ellipse, and its short axle is long
Degree is more than the diameter of end connector under arrester.
The acolite backing material is bismuth tin acolite, and its melting temperature is 150 DEG C.Also can holding according to design
Current vs. temperature is carried to reset；Acolite backing material can use Dongguan Wo Chang nonferrous materials factory product.
The present invention principle be：When circuit is by impacting with high pressure, Zinc-Oxide Arrester generation action, at the same time, eutectic
Alloy backing material also produces heat when being impacted by larger current, after the fusing of acolite backing material, arrester is not propped up
Support, at the top of the gravity and arrester under the elastic force effect of spring, arrester falls, therefore, can avoid occurring permanent earth thing
Therefore generation.
