Abstract
The utility model relates to a plug-pull lightning protector with retainer ring fixing mode, which comprises a lightning protector body and an end head which is fixedly connected with the lightning protector body, and also comprises a slot which is arranged on the upper end of the lightning protector body close to the end head position, an installation flange which is arranged outside the lightning protector body and a bottom board which is arranged on the bottom end of the lightning protector body, wherein the installation flange is clamped with the retainer ring through the slot, a clamping bolt is arranged on the installation flange, and the installation flange is fixedly connected with the bottom board. The plug-pull lightning protector enables the compression volume of the end head to be always in the saturation state, the pressure of the end head can not be reduced along time procession, and long term reliable operations of the lighting protector is guaranteed.
Description
Technical field
The utility model relates to a kind of lightning arrester, specifically relates to a kind of plug-in lightning arrester of band clasp fixed form.
Background technology
When installing, existing plug-in lightning arrester flange screw is connected by clamp nut, simultaneously power is delivered to base plate by flange, be delivered on the termination by body by base plate again, need pass through body because of the transmission of power, the power that is delivered to the termination weakens, and the decrement of termination has also been dwindled, As time goes on, the pressure of termination will further dwindle, and cause the termination insulation property to reduce, and bring potential safety hazard for the operation of lightning arrester.
Summary of the invention
The purpose of this utility model is to provide a kind of plug-in lightning arrester of band clasp fixed form, and its transmission that has solved lightning arrester compression bed knife in the background technology is long, As time goes on, and the technical problem that causes the termination insulation property to reduce.
Technical solution of the present utility model is:
A kind of plug-in lightning arrester of band clasp fixed form comprises lightning arrester body 1, and with the termination 2 that lightning arrester body 1 is connected, its special character is:
Comprise that also described lightning arrester body 1 upper end is near the draw-in groove 3 of tip position setting, the base plate 7 that is arranged at the mounting flange 4 in lightning arrester body 1 outside and is arranged at lightning arrester body 1 bottom; Described mounting flange 4 passes through snap ring 5 clampings with draw-in groove 3, and described mounting flange 4 is provided with fastening bolt 6, and described mounting flange 4 is connected with base plate 7.
Above-mentioned draw-in groove 3 is the cannelures that run through on the lightning arrester body 1.
Above-mentioned mounting flange 4 also can adopt mode such as bolt to be connected with snap ring 5.
The utility model makes snap ring and the draw-in groove of plug-in lightning arrester compression bed knife by being connected with flange, be directly delivered on the termination, make the decrement of termination reach the expection requirement, be in saturation condition always, As time goes on, the pressure of termination can not reduce yet, and has solved the hidden danger that prior art exists.
Description of drawings
Fig. 1 is the utility model structural representation.
The 1-lightning arrester body; The 2-termination; The 3-draw-in groove; The 4-mounting flange; The 5-snap ring; The 6-fastening bolt; The 7-base plate.
Embodiment
A kind of plug-in lightning arrester of band clasp fixed form, comprise lightning arrester body 1, with the termination 2 that lightning arrester body 1 is connected, comprise that also described lightning arrester body 1 upper end is near the draw-in groove 3 of tip position setting, the base plate 7 that is arranged at the mounting flange 4 in lightning arrester body 1 outside and is arranged at lightning arrester body 1 bottom; Described mounting flange 4 passes through snap ring 5 clampings with draw-in groove 3, and described mounting flange 4 is provided with fastening bolt 6, and described mounting flange 4 is connected with base plate 7.
Referring to Fig. 1, the utility model in use, because the draw-in groove 3 on mounting flange 4 and the lightning arrester body 1 is by snap ring 5 clampings, therefore fixed mounting flange 4 by fastening bolt 6, will compress bed knife simultaneously and be directly delivered on the termination 2, made the decrement of termination 2 reach the expection requirement, be in saturation condition always, As time goes on, the pressure of termination 2 can not reduce yet, and has guaranteed that lightning arrester moves reliably and with long-term.
