Abstract
The utility model provides a plug-in lightning arrester with a lead tube, connecting frames 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, whether the insulated conical head is connected in place cannot be determined, and the fixation method of the lightning arrester is complicated. 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, one end of the insulated conical head connected with the insulated lead is provided with a lead tube, and the lightning arrester body is arranged inside a mounting frame. According to the plug-in lightning arrester with the lead tube, the connecting frames and the pressure display device, due to the additional arrangement of the lead tube, the pressure display device and the mounting frame, the insulated lead at the root part of the insulated conical head is difficult to fracture, and the fixing structure of the lightning arrester body is simple.
Description
Technical field
The present invention relates to a kind of lightning arrester, be specifically related to a kind of plug-pull arrester with conduit link 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.
When installing in small space, be used for the limitation of operating 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.Simultaneously, when above-mentioned plug-pull arrester is installed lightning arrester body after grafting is finished, generally rely on flange or bindiny mechanism to realize, but no matter be to adopt flange or existing bindiny mechanism all comparatively complicated, and increased the weight of lightning arrester body, be unfavorable for the use of lightning arrester.
Summary of the invention
The invention provides a kind of plug-pull arrester with conduit link and pressure demonstration, mainly solved existing plug-pull arrester and be installed in the small space, whether long-term bending causes the equipment dependability conehead that reduces, can't determine to insulate to connect and put in place and problem that the lightning arrester body fixed form is comparatively complicated.
Technical solution of the present invention is as follows:
This plug-pull arrester with conduit link and pressure demonstration 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; 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; Described lightning arrester body comprises core body and is wrapped in the insulating barrier in the core body outside, described insulating barrier is centered by the lightning arrester body axis, the gear-like shell that outwards radiates, be provided with at least two annular grooves on the described gear-like shell, annular groove is nested with and is useful on the link that is fixedly connected with the equipment of being mounted, link comprises ring segment and linkage section, and ring segment is nested in the annular groove, and linkage section is connecting rod; 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 link and pressure provided by the invention is owing to having set up conduit, the insulated conductor of insulation conehead root is frangibility not, and by insulated conductor movement is stretched in the edge arbitrarily in the lightning arrester body position, be fixed in the limited installing space.
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; Simultaneously, installing rack framework provided by the invention is simple, and reliability is strong, can directly increase on the existing plug-pull arrester.

Embodiment
Below in conjunction with Fig. 1, Fig. 2 the present invention is described in detail, as shown in the figure:
This comprises the insulation conehead with the plug-pull arrester of conduit link 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.
Lightning arrester body comprises core body and is wrapped in the insulating barrier in the core body outside, described insulating barrier is centered by the lightning arrester body axis, the gear-like shell that outwards radiates, the gear-like shell be arranged so that lightning arrester is when carrying out overvoltage protection, the heat that core body produces can leave rapidly, has further improved the fail safe that equipment uses; Be provided with at least two annular grooves on the gear-like shell, annular groove is nested with and is useful on the link that is fixedly connected with the equipment of being mounted, and link comprises ring segment and linkage section, and ring segment is nested in the annular groove, and linkage section is connecting rod.
