Description

Tangible plug type lightning arrester
Technical field
The present invention relates to overvoltage protection lightning arrester field, be specifically related to a kind of tangible plug type lightning arrester being exclusively used in the high-voltage electrical equipment of protection gas-filled type insulation.
Background technology
The lightning arrester being generally used for insulation protection mainly adopts traditional ceramic coat or composite silicone rubber overcoat; product one end ground connection when installing and using; another termination high-pressure side; its shortcoming is that surface field intensity is very high in use; easily jeopardize personal safety, installation and maintenance is simultaneously also inconvenient, and external insulation structure adopted in addition is too simple; in damp and hot, filthy environment, easily occur surface discharge phenomena, the accident produced because of external insulation infringement happens occasionally.The scope of application of product is subject to certain restrictions.Particularly in recent years, rapidly, traditional lightning protection device is difficult to meet it and installs and uses requirement in inflating switch cabinet development.
Chinese patent ZL01265825.1 and ZL200620046285.3 discloses so a kind of tangible lightning arrester, this lightning arrester be connected to high-pressure side and low-pressure end, solid dielectric insulation is provided with between the shell that core body and conductor material are made, wherein be provided with earth terminal, dielectric front end is connection-peg, substantially achieve tangibly function, but the external insulation of this structure lightning arrester safety only relies on one deck solid dielectric, still there is the defect that reliability is not high.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of tangible plug type lightning arrester; shell non-hazardous high potential when using, tangible, install and maintenance is convenient, non-electromagnetic field interference, reliability is high simultaneously, long service life, cost are a low overvoltage protection lightning arrester, meet the Special use requirement of the compact electric equipments such as inflating switch cabinet completely.
For solving the problem, technical scheme of the present invention is:
A kind of tangible plug type lightning arrester, include cylindricality piezo-resistance core body, it is characterized in that: described cylindricality piezo-resistance core body is coated with dielectric in annular outward successively, annular semiconductor or conductor, annular external insulation medium, described cylindricality piezo-resistance core body upper end is connected with plug type joint, annular external insulation medium lower end is fixedly connected with annular base, the lower end of described annular base inwall is with ring-shaped step, a pressure relief channels is formed between described cylindricality piezo-resistance core body and annular base, pressure relief channels lower port is provided with annular flake, annular flake is provided with perforate, earth terminal extends in described pressure relief channels through perforate, and be fixedly connected with the bottom of described cylindricality piezo-resistance core body, described annular external insulation medium and annular base are coated with endless metal overcoat.
The height of described annular semiconductor or conductor is less than the height of dielectric in annular, and described annular semiconductor or conductor occupy the middle part in described annular outside dielectric
Core body of the present invention is formed by stacking by Zinc-oxide piezoresistor, and have excellent pressure-sensitive character (non-linear), assurance device can carry out good fit with the insulation of protected device.
Described tangible plug type lightning arrester, solid dielectric insulation between cylindricality Zinc-oxide piezoresistor core body and endless metal overcoat adopts the composite silicone rubber of excellent insulating property as dielectric, its dielectric is divided into inside and outside two-layer, the dielectric of every one deck all need the requirement meeting system nominal voltage withstand strength; Semiconductor or the conductor of annular is had in the outer setting of internal layer solid dielectric insulation, the height of this annular semiconductor or conductor should be less than the Zinc-oxide piezoresistor height in cylindricality core body, should ensure to be arranged at the middle part outside cylindricality Zinc-oxide piezoresistor core body, to reach the object making cylindricality Zinc-oxide piezoresistor core body surrounding electric field even intensity simultaneously; The present invention is because of the effect of annular semiconductor or conductor, make electric field distributing very evenly in dielectric, reduce the probability that dielectric damages because Electric Field Distribution is uneven, the inside and outside layer dielectric arranged in the present invention simultaneously all can meet the requirement of system nominal voltage withstand strength, even if one deck dielectric is damaged in running, device still can safe operation, has high security reliability.
The bottom of described tangible plug type lightning arrester arranges the relatively low passage of mechanical strength and pressure relief device, affects the safety of other electric equipments around to prevent from blasting during surge arrester failure.
Beneficial effect of the present invention:
The present invention in use, shell without danger, high potential, tangible, to install and maintenance is convenient, non-electromagnetic field interference, reliability is high simultaneously, long service life, cost are low, meet the Special use requirement of the compact electric equipments such as inflating switch cabinet completely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
