Abstract
The utility model relates to an arrester for overvoltage protection, especially to a touchable type metal oxide arrester used for overvoltage protection. The touchable type metal oxide arrester includes a grounding metal shell, a core body, and a pluggable joint, between the core body and the grounding metal shell is provided with a solid insulation medium with high dielectric strength, the shell is directly connected to ground, and the said core body is formed by overlapping and fastening of the zinc oxide valve plate and the upper and bottom electrodes. The utility model can satisfy the special operating requirements of some compact electrical equipments.
Description
Technical field
The utility model relates to the overvoltage protection lightning arrester, relates in particular to a kind of tangible formula metal oxide arrester that is used for overvoltage protection.
Background technology
The lightning arrester that generally is used for overvoltage protection mainly is traditional porcelain overcoat metal oxide arrester and polymeric metal oxide surge arrester, the general termination high-pressure side of product when installing and using, other end ground connection.This lightning arrester is the surface potential height in use, jeopardizes the person, device security easily, installs and uses and maintenance is made troubles to equipment, just can not satisfy at present the requirement of installing and using with the inflating switch cabinet of surprising speed development.Therefore the product scope of application is subjected to certain limitation.
Chinese patent ZL01265825.1 discloses a kind of such lightning arrester, the core body of this lightning arrester is connected to high-pressure side and low-pressure end, is provided with solid dielectric insulation between the shell that core body and conductor material are made, and which is provided with earth terminal, the dielectric front end is a connection-peg, has improved above-mentioned defective.But the structure of this lightning arrester and profile still can not satisfy the instructions for use of some compact electric equipment fully.
Summary of the invention
The technical problem that the utility model is intended to solve is an existing overvoltage protection lightning arrester surface potential height in use, jeopardizes the person, device security easily, installs and uses and maintenance is made troubles to equipment.The utility model provides a kind of tangible metal oxide arrester, thoroughly eliminates surperficial high potential, satisfies the special instructions for use of compact electric equipments such as inflating switch cabinet.
The utility model is achieved in that a kind of tangible formula metal oxide arrester, comprises grounded metal enclosure, core body, can plug joint and pressure relief device, and between core body and the grounded metal enclosure solid dielectric insulation of high dielectric strength.The direct ground connection of described shell, described core body are adopted zinc oxide valve plate and fastening the forming of upper and lower electrode stack.
The utility model core body adopts quality oxide zinc valve block and fastening the forming of upper/lower electrode stack, makes to the utlity model has good nonlinear characteristic.
Described tangible formula metal oxide arrester, adopt the splendid organic silicon rubber of good insulation preformance, elasticity as insulating barrier between core body and the shell, make the product good insulation preformance, be convenient to the installing hole that product inserts electric equipment again, and keep closely contact with it.
For improving surface of insulating layer and internal electric field distribution situation, described tangible formula metal oxide arrester will expose insulated part and be designed to truncated cone; The following frustum of a cone is to earthing your beautiful writings arc transition; One of top electrode in the core body is processed into hemisphere.
Described tangible formula metal oxide arrester, the core surface that contacts with the metal grounding shell partly sprays semi-conducting glaze, and extends to down frustum of a cone scope.
Described tangible formula metal oxide arrester bottom is provided with pressure release orifice, produces comminuted blast, the safety that jeopardizes other operational outfit when preventing the lightning arrester fault.Described tangible formula metal oxide arrester is provided with one simultaneously and connects the counter terminal, is user-friendly to the installation discharge counter, satisfies the special instructions for use that rated voltage is the compact electric equipments such as inflating switch cabinet of 10kV.
Description of drawings
Provide embodiment of the present utility model below in conjunction with accompanying drawing:
Fig. 1 partly cuts open figure for of the present utility model facing.
