Abstract
The utility model provides a plug type lightning arrester which mainly solves the problems of great weight, complex structure and high cost of the traditional plug type lightning arrester. A main body of the plug type lightning arrester comprises a core body and an insulating layer, a contact and a grounding device are arranged on the main body of the plug type lightning arrester, and the main body of the plug type lightning arrester is arranged on a bracket; the bracket is connected with an inner cone insulator through draw bars; and reinforcing ribs are arranged among the draw bars. Because the fixed draw bars are used for replacing an original metal shell, the weight is lightened, the structure form is simplified, and the cost is reduced.
Description
Technical field
The utility model relates to a kind of lightning arrester, is specifically related to a kind of plug-in lightning arrester.
Background technology
Existing plug-in lightning arrester is generally formed by contact, lightning arrester body, metal shell and earthing device, such plug-in lightning arrester is because the existence of metal shell, increase the weight of plug-in lightning arrester, made the complex structure of plug-in lightning arrester and production cost height.
Summary of the invention
The utility model provides a kind of plug-in lightning arrester, has solved mainly that existing plug-in lightning arrester weight is big, complex structure, problem that cost is high.
Technical solution of the present utility model is as follows:
This plug-in lightning arrester body is made of core body and insulating barrier, and lightning arrester body is provided with contact and earthing device, and lightning arrester body is arranged on the carriage; Carriage is connected with the inner cone insulator by pull bar; Be provided with reinforcement between the pull bar.
Above-described carriage is arranged at the bottom or the side of lightning arrester body.
The above carriage cooperates with the lightning arrester body side is concavo-convex.
The above pull bar one end is fixedlyed connected with carriage, and the other end directly is connected with the inner cone insulator; Or the other end directly is connected with the inner cone insulator after passing the flange that is arranged on the lightning arrester body; Or the other end is with after flange is connected, and flange is connected with the inner cone insulator again.
The above pull bar and reinforcement form network structure or lattice-shaped structure.
Above-described carriage is provided with spring, and spring one end is connected with carriage, and the other end is connected with lightning arrester body.
The above flange and/or carriage are provided with earthing device.
Above lightning arrester body outer surface only part is provided with conductive layer, and being provided with of conductive layer is same as the prior art.
Earthing device on the above-described lightning arrester body, earthing device on the flange and the earthing device on the carriage and conductive layer conducts or the part conduct; Earthing device on the lightning arrester body, the earthing device on the flange and the earthing device on the carriage conducts or the part conduct.
Advantage of the present utility model is:
The plug-in lightning arrester that the utility model provides owing to utilize steady brace to substitute original metal shell, so alleviated the weight of plug-in lightning arrester, has been simplified the version of plug-in lightning arrester, has reduced the cost of plug-in lightning arrester.
Description of drawings
Fig. 1 is a plug-in lightning arrester structural representation;
Fig. 2 is another structural representation of plug-in lightning arrester.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in Figure 1 and Figure 2:
This plug-in lightning arrester comprises the lightning arrester body 2 that is made of core body and insulating barrier, and lightning arrester body 2 is provided with contact 1 and earthing device 4, and lightning arrester body 2 is arranged on the carriage 3; Carriage 3 is connected with the inner cone insulator by pull bar 5; Be provided with reinforcement 6 between the pull bar 2, pull bar 5 forms network structure or lattice-shaped structure with reinforcement 6.
Can also be provided with spring 7 on the carriage 3, spring 7 one ends are connected with carriage 3, the other end is connected with lightning arrester body 2, the purpose that spring is set is to tensile force of lightning arrester body, the contact portion that prevents lightning arrester body and inner cone insulator shrinks distortion because of factors such as overlong time, thereby cause the contact portion decrement to weaken, influence insulation and sealing.
Wherein being connected of pull bar and inner cone insulator can be by following three kinds of modes:
1, pull bar one end is fixedlyed connected with carriage, and the other end directly is connected with the inner cone insulator; This connected mode belongs to pull bar and directly is connected with the inner cone insulator; As shown in Figure 1;
2, pull bar one end is fixedlyed connected with carriage, and the other end directly is connected with the inner cone insulator after passing the flange that is arranged on the lightning arrester body, and flange herein mainly plays the spacing guide effect to pull bar; This connected mode also belongs to pull bar and directly is connected with the inner cone insulator; As shown in Figure 2;
3, pull bar one end is fixedlyed connected with carriage, the other end is with after flange is connected, flange is connected with the inner cone insulator again, and the part because the pull bar, flange and the lightning arrester body that are provided with on the carriage, carriage link into an integrated entity is fixedlyed connected flange by modes such as bolts then with the inner cone insulator; This connected mode belongs to pull bar and is connected indirectly with the inner cone insulator.
Also can be provided with or all have earthing device respectively on flange, the carriage 3.Earthing device can be set all yet.
Lightning arrester body outer surface only part is provided with conductive layer, and being provided with of conductive layer generally is in the lightning arrester surface-coated conductive paint or conducting resinl to be arranged, the position of coating, material and how to apply same as the prior art.
Earthing device (if setting) on earthing device on the lightning arrester body, the earthing device on the flange (if setting) and the carriage conducts with conductive layer or part conducts; Earthing device on the lightning arrester body, the earthing device on the flange and the earthing device on the carriage conducts or the part conduct.
This plug-in lightning arrester does not use the metal shell of existing lightning arrester body outer setting, simultaneously, has adopted the mode of multiple pull bar that lightning arrester is connected with the inner cone insulator, both guaranteed bonding strength, alleviated weight again, the form that simplifies the structure has reduced processing cost.
