Abstract
The utility model discloses a lightning arrester with an organic shell, which is suitable for the overvoltage protection of electrical equipment such as line traps. An upper and a lower aluminium cushion blocks in an existing lightning arrester are eliminated, a flat spring and electrode sheets form an electric connection with an upper and a lower two terminals, an existing core envelop structure which is formed by the spiral winding of epoxy glass silk ribbons is replaced by a silicone rubber isolation medium layer, the problem that aluminium cushion blocks generate eddy currents and heat to influence the service life of valve sheets and shorten the usage time of the lightning arrester is eliminated, the core crazing of the lightning arrester is difficult to occur, and in addition, an upper end cover adopts a big creepage distance single skirt structure, and an existing multiple skirt silicone rubber outer sleeve is replaced by the single layer thermoplast outer sleeve and the big creepage distance single skirt structure. The utility model has the advantages of simple manufacture technology of the whole body, and low cost.
Description
The utility model discloses a kind of organic shell lightning arrester, be applicable to the overvoltage protection of electric equipments such as line trap, compensation condenser, switch cubicle.
At present, the structure of organic shell lightning arrester is, it has upper connecting terminal, lower connecting terminal, one group of valve block, aluminium cushion block up and down, the core body envelope, many skirts silastic material, wherein, one group of valve block is vertically enumerated layout, folder cushions lead flake between valve block, two termination lead pad pieces, wrap up in the core body envelope outward, the core body envelope is that the expoxy glass silk ribbon is entwined in a spiral manner, many skirts of core body envelope overcoat silastic material, on, lower connecting terminal passes respectively, hole on the following aluminium cushion block, screw on the upper and lower end face that is fixed on the valve block group, the upper and lower end face of many skirts silastic material is linked closely fixing by teabowl with a cover up and down respectively.The lightning arrester of this structure exists following shortcoming: when working in lightning arrester is having the environment of power frequency magnetic field (as: lightning arrester is installed in the line trap), aluminium cushion block in the lightning arrester produces eddy current and generates heat, this will reduce the useful life of valve block, shortens the service time of lightning arrester; Simultaneously, different and differ greatly because of valve block, aluminium cushion block, core body envelope three's thermal coefficient of expansion, when expanding with heat and contract with cold the coefficient of expansion of aluminium cushion block greater than valve block, both are different again with the core body envelope, therefore, the three can not be expanded harmoniously or shrink, and causes lightning arrester after operation a period of time, the core body be full of cracks can occur, cause valve block to make moist and cisco unity malfunction, shorten the service time of lightning arrester; In addition, also there is complex process in the many skirts silastic material on the lightning arrester, the problem that cost is high.
The purpose of this utility model provides a kind of organic shell lightning arrester of new structure, have prolong lightning arrester service time, characteristics that cost is low.
The purpose of this utility model is achieved in that a kind of organic shell lightning arrester, it has upper connecting terminal, lower connecting terminal, one group of valve block, aluminium flake, valve block is vertically enumerated layout, folder cushions lead flake between valve block, it also has large distance upper end cover 1, electrode slice, planar spring, the spacer medium layer, insulating sleeve, insulating sleeve, bottom end cover, upper connecting terminal is fixed on the upper end cover and electrically connects with the pole piece that powers on, planar spring, one group of valve block, the bottom electrode sheet vertically superposes in order and enumerates, the overcoat insulating sleeve, tape splicing has the bottom end cover of the through hole that injects the spacer medium layer under the insulating sleeve, is fixed with lower connecting terminal on the bottom end cover, insulating sleeve overcoat insulating sleeve.
The utility model has the advantages that:, therefore, eliminated the aluminium cushion block and produced eddy current and generate heat and then influence valve block and shorten the lightning arrester problem of service time useful life because organic shell lightning arrester described in the utility model has been cancelled up and down aluminium cushion block; Owing to adopted planar spring and electrode slice and last lower connecting terminal to electrically connect, substitute the existing core body envelope structure that is entwined with expoxy glass silk ribbon spiral with silicon rubber spacer medium layer, make an elastic layer (spacer medium layer) is arranged between arrester valve piece made group and the insulating sleeve, can not occur the core body be full of cracks because of expanding with heat and contract with cold, prolong its service time; In addition, because the utility model upper end cover adopts the large distance single shirt structure, it and monolayer thermoplastic overcoat have substituted existing many skirts silastic material, and process for integrally manufacturing is simple, cost is low.
Fig. 1 is organic shell lightning arrester structural representation described in the utility model;
In conjunction with the embodiments the utility model structure is described in further detail below by accompanying drawing:
Embodiment 1:
As shown in Figure 1, a kind of organic shell lightning arrester, it has upper end cover 1, upper connecting terminal 2, electrode slice 3, planar spring 4, one group of valve block 8, lead flake 9, bottom end cover 10, lower connecting terminal 11, spacer medium layer 5, insulating sleeve 6, insulating sleeve 7;
Upper connecting terminal 2 is fixed on the upper end cover 1 and electrically connects with the pole piece 3 that powers on, the pole piece 3 that powers on is close on the inner plane of large distance upper end cover 1, planar spring 4, one group of valve block 8, bottom electrode sheet 3 vertically superposes in order and enumerates, 8 folders of valve block cushion lead flake 9,8 of planar spring 4 and valve blocks also accompany electrode slice 3, overcoat insulating sleeve 6, bottom end cover 10 is filled in one group of valve block 8 that insulating sleeve 6 will vertically enumerate and is fixed, lower connecting terminal 11 is fixed on the bottom end cover 10, electrically connect with bottom electrode sheet 3, have through hole 12 on the bottom end cover 10, silicon rubber via through holes 12 injects, with insulating sleeve 6, the gap of valve block 8 inter-modules such as grade is filled up, and is frozen into spacer medium layer 5, insulating sleeve 6 overcoat insulating sleeves 7.
