Abstract
The utility model relates to the field of circuit protection, and in particular relates to a surge arrester. The surge arrester comprises a shell, a tray, a spring and a zinc oxide resistor sheet, wherein the shell and the tray form a closed space; the zinc oxide resistor sheet is arranged in the shell; two ends of the zinc oxide resistor sheet are respectively connected with an upper conductor and a lower conductor; the lower conductor is fixedly connected with the tray; the spring in a compression state is further arranged between the zinc oxide resistor sheet and the tray; the lower conductor is positioned in the spring. According to the scheme, a voltage overload protector can be conveniently arranged on a low-voltage overhead line.
Description
Technical field
The utility model relates to circuit protection field, refers in particular to a kind of surge arrester.
Background technology
The system that lightning overvoltage and LEMP cause and the damage of equipment are more and more.Therefore, solve as early as possible building and electronic information the Lightning Protection problem seems very important.Along with the increasingly stringent that relevant device requires lightning protection, the surge on installation protector limiting circuitry and instantaneous overvoltage, the overcurrent of releasing on circuit become one of important step of Modern Lightning Protection Technology.
For the overload on low-voltage overhead line road, the inventor develops a kind of surge arrester, and this case produces thus.
Utility model content
The purpose of this utility model is to provide surge arrester, and voltage overload protection can be set very easily on low-voltage overhead line road.
To achieve these goals, the technical solution of the utility model is as follows:
Surge arrester, comprises shell, pallet, spring, zinc oxide resistance sheet; Described shell and pallet form an airtight space, described zinc oxide resistance sheet setting in the enclosure, the two ends of zinc oxide resistance sheet are connected with lower conductor with upper conductor respectively, and lower conductor is fixedly connected with pallet, between zinc oxide resistance sheet and pallet, be also provided with the spring in compressive state, described lower conductor is arranged in spring.
Further, described surge arrester also comprises support bar, and described support bar is arranged on the below of pallet.
Further, described shell comprises pillar, and pillar and shell are integral type structure, and described support bar is connected with lower conductor by pillar.
Further, described pallet face is down reflective surface.
Adopt after such scheme, the utility model compared with prior art, has the following advantages:
When surge arrester because of overheated, puncture while losing efficacy, can automatically it be departed from from electrical network, provide reflective indication simultaneously.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the schematic diagram after Fig. 1 pallet departs from.
Label declaration
Shell 1, pallet 2, spring 3, zinc oxide resistance sheet 4, upper conductor 5, lower conductor 6,
Support bar 7, pillar 8.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in the figure, the surge arrester that the utility model discloses, comprises shell 1, pallet 2, spring 3, zinc oxide resistance sheet 4; Described shell 1 and pallet 2 form an airtight space, and pallet 2 face is down reflective surface; Described zinc oxide resistance sheet 4 is arranged in shell 1, the two ends of zinc oxide resistance sheet 4 are connected with lower conductor 6 with upper conductor 5 respectively, wherein lower conductor 6 with zinc oxide resistance sheet 4 for being threaded, and lower conductor 6 is fixedly connected with pallet 2, between zinc oxide resistance sheet 4 and pallet 2, be also provided with the spring 3 in compressive state, described lower conductor 6 is arranged in spring 3.
On shell 1, comprise pillar 8, pillar 8 is integral type structure with shell 1, pillar 8 is for the support bar 7 of connecting trays 2 belows, support bar 7 is also connected with lower conductor 6, when zinc oxide resistance sheet 4 fusing, the pallet 2 falling can block by supported bar 7, by the give out light variation of face of pallet 2 belows, can find zinc oxide resistance sheet 4 fusing.
Upper conductor 5 can be made the structure of a T font, is fixed on the lower end of puncture connector, during use, and only need be by the upper end folder of puncture connector on the line.
Above are only specific embodiment of the utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection range.
