Abstract
The utility model discloses a suspension type lightning arrester with a release device. The suspension type lightning arrester comprises a lightning arrester body, an insulator, a release device, a connecting line and an elastic part, wherein the lightning arrester body is arranged vertically, and the bottom end of the lightning arrester body is provided with a connecting anchor clamp; the insulator is arranged horizontally, one end of the insulator is connected with the connecting anchor clamp, and one end of the release device is connected with the other end of the insulator through a connecting plate; the connecting line and the elastic part are connected with the other end of the release device and the connecting anchor clamp. According to the utility model, after the release device of the suspension type lightning arrester moves, a relatively large air gap can be formed, so that the condition of air gap breakdown is effectively prevented.
Description
Technical field
The utility model relates to a kind of suspended-type surge arrester with release unit, belongs to lightning arrester structural design field.
Background technology
Suspended-type surge arrester, especially line type suspended-type surge arrester operation occasion, generally on high mountain shaft tower, has suitable difficulty for Daily Round Check.The lightning arrester of conventional belt release unit, generally with straight connecting rod or directly connect high-pressure side with wire, when release unit action, straight connecting rod or the wire bottom, form certain air gap, but at strong wind weather, connecting rod or wire can be with putting in wind action, and air gap distance too little (distance only has 30mm left and right), may cause air gap to puncture, form single phase ground fault, thereby cause large-area power outage.In addition, existing lightning arrester need to install insulation system additional when monitoring equipment is installed between lightning arrester and tower grounding, generally to install a suspension insulator additional or at lightning arrester upper end installing insulating base, in addition also need to increase series installation gold utensil or electric armour clamp, so not only increase cost, and strengthened installation workload.
Utility model content
The purpose of this utility model is the deficiency overcoming in background technology, thereby provide a kind of suspended-type surge arrester rational in infrastructure, release unit in this suspended-type surge arrester, after action, can form larger air gap, effectively avoids occurring the situation that air gap punctures.
The technical scheme that realizes the utility model object is:
With a suspended-type surge arrester for release unit, comprise lightning arrester body, insulator and release unit; Described lightning arrester body vertically arranges, and the bottom of described lightning arrester body is provided with connection gold utensil; Described insulator level arranges, and one end of described insulator is connected with the described gold utensil that is connected, and one end of described release unit is connected with the other end of described insulator by connecting plate;
Described suspended-type surge arrester also comprises the other end and described connecting line and the elastic component that is connected gold utensil that connects described release unit.
In technique scheme, described elastic component is spiral tension spring.
In technique scheme, described spiral tension spring is enclosed within on described connecting line.
In technique scheme, described connecting line is copper braid over braid.
In technique scheme, described lightning arrester body is provided with the earth stud of loosing core.
The utlity model has positive effect: (1) is used suspended-type surge arrester of the present utility model, in electric power system, break down or when lightning arrester goes wrong, release unit action, the elastic component being originally stretched shrinks rapidly, make lightning arrester and wire hightail and form enough large air gap, by fault lightning arrester and isolation of system, guarantee system uninterrupted power supply.(2) in suspended-type surge arrester of the present utility model, owing to being provided with the earth stud of loosing core on described lightning arrester body, when monitoring equipment is installed, can directly monitoring equipment be connected with the earth stud of loosing core, and need not install a suspension insulator or installing insulating base additional, and corresponding fitting or electric armour clamp; Easy for installation, and provide cost savings.
Accompanying drawing explanation

Reference numeral shown in figure is: 1-lightning arrester body; The 11-earth stud of loosing core; 2-insulator; 3-release unit; 4-connects gold utensil; 5-connecting line; 6-elastic component.
Embodiment
Below in conjunction with Figure of description, a kind of embodiment of the suspended-type surge arrester with release unit of the present utility model is elaborated:
As shown in Figure 1, a kind of suspended-type surge arrester with release unit, comprises lightning arrester body 1, insulator 2 and release unit 3; Described lightning arrester body 1 vertically arranges, and the bottom of described lightning arrester body 1 is provided with and connects gold utensil 4; Described insulator 2 is horizontally disposed with, and one end of described insulator 2 is connected with the described gold utensil 4 that is connected, and one end of described release unit 3 is connected with the other end of described insulator 2 by connecting plate; The described suspended-type surge arrester of the present embodiment also comprises connection described release unit 3 other ends and described connecting line 5 and the elastic component 6 that is connected gold utensil 4.Use the suspended-type surge arrester of the present embodiment, in electric power system, break down or when lightning arrester goes wrong, release unit 3 actions, the elastic component 6 being originally stretched shrinks rapidly, make lightning arrester and wire hightail and form enough large air gap, by fault lightning arrester and isolation of system, guarantee system uninterrupted power supply.
The described elastic component 6 of the present embodiment is spiral tension spring, and described spiral tension spring is enclosed within on described connecting line 5.The described connecting line 5 of the present embodiment is copper braid over braid, and certain described connecting line 5 can be also flexible conductor.
The described lightning arrester body 1 of the present embodiment is provided with the earth stud 11 of loosing core, in suspended-type surge arrester of the present utility model, owing to being provided with the earth stud 11 of loosing core on described lightning arrester body 1, when monitoring equipment is installed, can directly by monitoring equipment is installed, be connected with the earth stud 11 of loosing core, and need not install a suspension insulator or installing insulating base additional, and corresponding fitting or electric armour clamp, easy for installation, and provide cost savings.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.
