Abstract

The utility model provides a plug-in lightning arrester with a lead tube, and mainly solves the problem that the existing plug-in lightning arrester is installed in a narrow space, thus the equipment reliability is reduced by bending the lightning arrester for a long time. The plug-in lightning arrester comprises an insulated conical head, wherein one end of the insulated conical head is provided with a contact, the other end is connected with a lightning arrester body through an insulated lead, and one end of the insulated conical head connected with the insulated lead is provided with a lead tube. According to the plug-in lightning arrester with the lead tube, due to the additional arrangement of the lead tube, the insulated lead at the root part of the insulated conical head is difficult to fracture.

Description

Plug-pull arrester with conduit

Technical field

The present invention relates to a kind of lightning arrester, be specifically related to a kind of plug-pull arrester with conduit.

Background technology

The insulation conehead of existing plug-pull arrester and lightning arrester body generally are fixedly installed as a whole, and in the smaller situation of installing space, the staff can't carry out fitting operation in small space, even lightning arrester can't enter installing space and installs.

In order to address the above problem, the technical staff provides a kind of plug-pull arrester, be connected by insulated conductor between insulation conehead and the lightning arrester body, because insulated conductor is flexible material, therefore insulating between conehead and the lightning arrester body can Arbitrary Rotation, but this structure is brought a new problem.

Because lightning arrester is installed in the small space, insulated conductor needs bending, and the stress that long-term bending produces may cause poor wire connection or directly fracture, thereby causes equipment dependability lower.

Summary of the invention

The invention provides a kind of plug-pull arrester with conduit, mainly solved existing plug-pull arrester and be installed in the small space, the problem that long-term bending causes equipment dependability to reduce.

Technical solution of the present invention is as follows:

This plug-pull arrester with conduit comprises the insulation conehead, and insulation conehead one end is provided with contact, and the other end is established by insulated conductor and is connected with lightning arrester body; Be provided with on the described insulation conehead and use fixed connection apparatus, described insulation conehead is connected on the end with insulated conductor and is provided with conduit, the length of conduit is 0.5 ~ 1.5 times of insulation conehead length, conduit is divided at least two sections, and the hardness of each section lead pipe reduces successively along insulation conehead to lightning arrester body direction.

The invention has the advantages that:

Plug-pull arrester with conduit provided by the invention is owing to set up conduit, and the insulated conductor of insulation conehead root is frangibility not, and by insulated conductor with the lightning arrester body position arbitrarily along stretching movement, be fixed in the limited installing space.

Embodiment

Below in conjunction with Fig. 1 the present invention is described in detail, as shown in Figure 1:

This comprises the insulation conehead with the plug-pull arrester of conduit, and insulation conehead one end is provided with contact, and the other end is established by insulated conductor and is connected with lightning arrester body; The insulation conehead is connected on the end with insulated conductor and is provided with conduit, the length of conduit is 0.5 ~ 1.5 times of insulation conehead length, concrete length should be determined according to the toughness of wire, conduit is divided at least two sections, the hardness of each section lead pipe reduces successively along insulation conehead to lightning arrester body direction, the stress that the wire bending produces, the problem of having avoided the long-term bending of wire to rupture can be greatly alleviated in arranging of conduit.

Claims

1. the plug-pull arrester with conduit comprises the insulation conehead, and insulation conehead one end is provided with contact, and the other end is established by insulated conductor and is connected with lightning arrester body; It is characterized in that: described insulation conehead is connected on the end with insulated conductor and is provided with conduit, the length of conduit is 0.5 ~ 1.5 times of insulation conehead length, conduit is divided at least two sections, and the hardness of each section lead pipe reduces successively along insulation conehead to lightning arrester body direction.
