The existing lightning arrester is installed on a cross arm, a supporting insulator needs to be installed additionally, the supporting insulator is utilized to share the dragging force of a line cable, an insulating protective cover needs to be wrapped outside all electrical appliance contacts and live metal pieces, in addition, the protective area of the insulating protective cover is large, an insulating fault is easily caused, and the normal use of equipment is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problem that a supporting-free protective type arrester which can remove the installation supporting insulator and simplify the complex construction process is provided.
In order to solve the technical problem, the utility model discloses a technical scheme is:
the utility model relates to an exempt from to support protection type arrester, including arrester body and supporting insulator, supporting insulator is concave column, all is equipped with the full skirt inside and outside the concave column, and the supporting insulator upper portion outside is equipped with binding post, goes up the binding post outside and is equipped with insulating sheath.
The upper wiring terminal is fixed on a boss, and an annular groove is formed in the outer ring of the boss; the insulating sheath is wrapped outside the upper wiring terminal, and an insulating sheath sealing ring is arranged on the inner side of the insulating sheath and is installed in an annular groove in the boss.
The insulating sheath is completely wrapped outside the upper outgoing line terminal, and the cable penetrates through the tail part of the insulating sheath and is fixed on the upper outgoing line terminal.
The utility model has the following beneficial effects and advantages:
1. the utility model discloses a utility model aims at integrating arrester and supporting insulator to having carried out optimal design with supporting insulator, having made it both have the supporting role, having the guard action again, removing installation supporting insulator from, insulating lag is small and exquisite pleasing to the eye, has simplified loaded down with trivial details construction technology, has improved the life of equipment.
