Abstract

The utility model provides a plug-in lightning arrester with a lead tube and a pressure display device, and mainly solves the problems 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, and whether the insulated conical head is connected in place cannot be determined. 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 and the pressure display device, due to the additional arrangement of the lead tube, the pressure sensors and the display device, the insulated lead at the root part of the insulated conical head is difficult to fracture, and the mounting accuracy is high.

Description

Plug-pull arrester with conduit and pressure demonstration

Technical field

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

Background technology

The insulation conehead of existing plug-pull arrester and lightning arrester body generally are fixedly installed as a whole, in the situation that installing space is smaller, 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.

Simultaneously, when installing, be used for the limitation of operating space in small space, whether technical staff difficult assurance is in place, if be not in place, thereby owing to exists gap possibility guiding discharge to damage the equipment of lightning arrester or installation.

Summary of the invention

The invention provides a kind of plug-pull arrester with conduit and pressure demonstration, mainly solved existing plug-pull arrester and be installed in the small space, long-term bending causes equipment dependability reduction, the conehead of can't determining to insulate whether to connect the problem that puts in place.

Technical solution of the present invention is as follows:

This plug-pull arrester with conduit and pressure demonstration comprises insulation conehead and lightning arrester body, 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; Described insulation conehead is connected on the end with insulated conductor and is provided with conduit, and the length of conduit is 0.5 ~ 1.5 times of insulation conehead length, and 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; Be fixedly installed the Three pressures transducer on the described insulation conehead, the Three pressures transducer is emanant distribution centered by insulation conehead center line, be provided with the display unit that shows for the pressure that pressure sensor is detected on the lightning arrester body, pressure sensor is connected by insulated conductor with display unit.

Above-mentioned display unit is display panels.

The invention has the advantages that:

The plug-pull arrester that shows with conduit and pressure provided by the invention is owing to having 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.

Simultaneously, owing to having set up the pressure demonstration, installation personnel can directly obtain real-time pressure value by the display unit that is arranged on the lightning arrester body, has improved the accuracy of installing.

Embodiment

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

This comprises insulation conehead and lightning arrester body with the plug-pull arrester of conduit and pressure demonstration, 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.

Be fixedly installed the Three pressures transducer on the insulation conehead, the Three pressures transducer is emanant distribution centered by insulation conehead center line, be provided with the display unit that shows for the pressure that pressure sensor is detected on the lightning arrester body, pressure sensor is connected by insulated conductor with display unit; During installation, pressure sensor pressurized generated data also transfers to display unit, display unit directly shows pressure data, installation personnel can directly obtain real-time pressure value by the display unit that is arranged on the lightning arrester body, can guarantee bonding strength, can guarantee again can not cause because pressure is excessive contact to damage.
