Abstract
The utility model provides an outdoor fixed lightning arrester with a buffer layer, and mainly solves the problems that the existing outdoor fixed lightning arrester has complicated structure, low reliability and high manufacturing cost, and the installation and matching need to be conducted by using a supporting insulator. The outdoor fixed lightning arrester with the buffer layer comprises a lightning arrester body and a rigid casing, wherein one end of the rigid casing is provided with a wire inlet pipe, and the inwall of the wire inlet pipe is provided with an insulating rubber buffer layer. According to the outdoor fixed lightning arrester with the buffer layer, the wire inlet pipe of high strength, long length and large thickness is arranged, thus the tension of the conducting wire is transferred to the wire inlet pipe and the casing, and the tension on the lightning arrester by the conducting wire is avoided; and the insulating rubber buffer layer is additionally arranged, thereby preventing the lead from being damaged due to the long-term contact of the high-tension lead and the rigid member.
Description
Technical field
The utility model belongs to the lightning arrester field, is specifically related to the fixed lightning arrester in a kind of open air.
Background technology
Existing outdoor fixed lightning arrester, cause the high pressure end of incoming cables to be damaged for fear of other weather conditions such as wind-force, the general employing at post insulator of lightning arrester next door parallel device, or take post insulator directly and lightning arrester connect as one the mode of part, high-voltage conducting wires is connected with post insulator first, be connected to again the high pressure end of incoming cables of lightning arrester by wire jumper, like this pulling force of wire shared by insulation column, guaranteed the operation that lightning arrester is safe and reliable.But the equal complex structure of aforesaid way, take up room large, install loaded down with trivial details.
Summary of the invention
The utility model provides a kind of outdoor fixed lightning arrester with resilient coating, has mainly solved the fixed lightning arrester complex structure in existing open air, reliability is low, manufacturing cost is high, needs to use post insulator that supporting problem is installed.
Technical solution of the present utility model is:
This comprises lightning arrester body and stiff case with the outdoor fixed lightning arrester of resilient coating, and lightning arrester body is fixedly installed in the stiff case; Described stiff case one end is provided with the inlet wire pipe that is connected with the lightning arrester high-voltage terminal for high-voltage conducting wires, described inlet wire pipe length is 15cm ~ 30cm, the inlet wire pipe pipe thickness is 1cm ~ 2cm, and the housing bottom arranged outside has the holder that is fixedly connected with mounted piece; Described inner walls is provided with insulating barrier; Be provided with the electro-insulating rubber resilient coating on the described inlet wire pipe inwall, the electro-insulating rubber resilient coating is fixedly connected with the inlet wire pipe inwall, and the thickness of electro-insulating rubber resilient coating is 0.8 ~ 1cm.
The utility model advantage is as follows:
This with the outdoor fixed lightning arrester of resilient coating because lightning arrester is arranged in the housing, simultaneously, end of incoming cables at housing is provided with high strength, the inlet wire pipe of length and thickness, the direct like this pulling force with wire is transferred on inlet wire pipe and the housing, avoided lightning arrester to be subjected to wire tension, increased the electro-insulating rubber resilient coating, avoided high-voltage conducting wires directly and the rigid member Long Term Contact, may cause the problem of harness damage, guaranteed the reliability service of lightning arrester, got rid of the potential safety hazard that causes to power system operation, product has simple in structure, take up room little, the advantage such as easy for installation.
Description of drawings
Fig. 1: structural representation of the present utility model.
Wherein: the 1-lightning arrester body; The 2-stiff case; The 3-inlet wire pipe; 4-buffer insulation layer.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
This outdoor fixed lightning arrester with resilient coating comprises lightning arrester body and rigidity cylindrical shell, and lightning arrester body is fixedly installed in the rigidity cylindrical shell; Rigidity cylindrical shell one end is provided with the inlet wire pipe that is connected with the lightning arrester high-voltage terminal for high-voltage conducting wires, and inlet wire pipe length is 15cm ~ 30cm, and the inlet wire pipe pipe thickness is 1cm ~ 2cm, and the housing bottom arranged outside has the holder that is fixedly connected with mounted piece; Described inner walls is provided with insulating barrier.The rigidity cylindrical shell should be two members and is movably connected to form integral piece, is convenient to replacing and the maintenance of lightning arrester body; Simultaneously, also set up the electro-insulating rubber resilient coating on the inlet wire pipe inwall, the electro-insulating rubber resilient coating is fixedly connected with the inlet wire pipe inwall, and the thickness of electro-insulating rubber resilient coating is 0.8 ~ 1cm.
In use, at first, the direct pulling force with wire of setting up of inlet wire pipe shifts, and avoids direct high-voltage terminal effect to lightning arrester body after the installation; Secondly, if damage after the long-term use of inlet wire pipe, then directly change housing and get final product, and can not produce any impact to lightning arrester body, and the cost of housing is far below the cost of lightning arrester body; Again, the inlet wire pipe inwall has been set up electro-insulating rubber, has avoided high-voltage conducting wires directly and the rigid member Long Term Contact, may cause the problem of harness damage.
