Abstract
The utility model discloses an overvoltage protector sheath and belongs to the field of electrical equipment. The main body of the overvoltage protector sheath is a sleeve. The overvoltage protector sheath is characterized in that the sleeve is of a cylindrical structure, a wire outlet is connected at the top of the sleeve, the bottom of the sleeve is of a hollow structure, the wire outlet is of a cylindrical structure and concentric with the sleeve, the diameter of the wire outlet is smaller than that of the sleeve, and a spiral coil is arranged on the outer wall of the wire outlet. The overvoltage protector sheath is simple in structure, reasonable in design and high in flexibility and tearing resistance, and the synthetic silica rubber material cannot deform. The overvoltage protector sheath is applied to insulating protection of a wiring portion of an overvoltage protector and can effectively avoid power off caused by leak-off short circuit.
Description
Technical field
The utility model relates to field of electrical equipment, relates in particular to a kind of overvoltage protection device sheath.
Background technology
In electric equipment and radio-circuit, overvoltage protection device is avoided superpotential infringement mainly for the protection of the insulation of the electric equipments such as generator, transformer, vacuum switch, bus, motor.
At the branch thicket,, after branch, crotch drop on wire accidentally, may cause the overhead wire short circuit, thereby cause power failure through out-of-date if any overhead transmission line.In wiring place of high-low pressure transformer, on-load switch, lightning arrester, overvoltage protection device, fuse etc., creep and also can cause short circuit if any fall upper, toy of foreign matter.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of overvoltage protection device sheath simple in structure, reasonable in design.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of overvoltage protection device sheath, its main body is a body, it is characterized in that: described body is cylindrical structural; described body top is connected with line outlet; the bottom is hollow-core construction, and described line outlet is and the body concentric cylindrical structural of cover that described line outlet diameter is less than the body diameter.
Described line outlet outer wall is provided with bung flange.
Described body and line outlet are the silastic elastomer material.
The beneficial effects of the utility model are: the utility model is simple in structure, and is reasonable in design, and the silastic elastomer material never is out of shape, and pliability and lancinating are high; Apply to the insulating protection of overvoltage protection device wiring place, can effectively solve the outage that causes because leaking disconnected short circuit.
