Description

A kind of New Zinc Oxide Lightning Arrester
Technical field
The utility model relates to a kind of zinc oxide arrester, particularly relates to a kind of New Zinc Oxide Lightning Arrester.
Background technology
Lightning arrester is voltage protector again; be used to a kind of overvoltage protection suppressing temporary overvoltage; the interference such as lightning overvoltage, internal overvoltage and power frequency rising are got rid of for high-tension apparatus; ensure that the high-tension apparatus such as high-tension line and transformer is from superpotential interference and infringement; existing lightning arrester generally adopts body to be the lightning arrester of gapless type, in addition at top series gap, cause due to the wind of wire put, vibration etc.; discharging gap distance is made to have comparatively big error, discharge instability.
Utility model content
For the present situation of above-mentioned prior art, it is fixing that technical problem to be solved in the utility model is to provide a kind of ball sphere gap distance, discharge stability, the New Zinc Oxide Lightning Arrester that volume is little and easy for installation.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of New Zinc Oxide Lightning Arrester, comprise lightning arrester body, described lightning arrester body is provided with the first ball discharge and the second ball discharge, the clearance distance of this first ball discharge and the second ball discharge is 40mm, described first ball discharge, the second ball discharge and lightning arrester body are one-body molded, top and the bottom of described lightning arrester body are equipped with binding post, the height of this lightning arrester body is 270mm, and the width of lightning arrester body is 82mm.
Further, described lightning arrester body skin is provided with silastic-layer.
Compared with prior art, the utility model has the advantage of: the utility model by the first ball discharge, the second ball discharge and lightning arrester directly integrally, ensure that ball sphere gap distance is fixing, discharge stability, and easy for installation, do not need adjustment ball sphere gap distance, the utility model is reasonable in design, accord with the demands of the market, be applicable to large-scale promotion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of New Zinc Oxide Lightning Arrester, comprise lightning arrester body 1, described lightning arrester body 1 is provided with the first ball discharge 2 and the second ball discharge 3, the clearance distance of this first ball discharge 2 and the second ball discharge 3 is 40mm, described first ball discharge 2, second ball discharge 3 is one-body molded with lightning arrester body 1, ensure that ball sphere gap distance is fixing, discharge stability, top and the bottom of described lightning arrester body 1 are equipped with binding post 4, the height of this lightning arrester body 1 is 270mm, the width of lightning arrester body 1 is 82mm, volume is little, easy for installation, described lightning arrester body 1 skin is provided with silastic-layer, hydrophobicity is strong, anti-pollution characteristic is good, resistance to galvanic corrosion, anti-aging, convenient transport.
This lightning arrester is mainly used on 10 kilovolts of electric power system power transmission lines, protection circuit insulator, prevent 10 kilovolts of overhead wire lightning-caused breakings and insulator arc-over, itself and insulator are installed in parallel, by zinc oxide current limiting element, the common cooperation of the series gap between current limiting element drainage ball and high-pressure induct ball and reach the object of lightning protection, when circuit is subject to affecting of lightning impulse overvoltage or power-frequency overvoltage, can before overvoltage reaches the critical point of insulator arc-over, lightning-protection overvoltage protector gap discharge, zinc oxide arrester action, overvoltage is introduced the earth, guarantee the normal work of insulator and wire, in normal work, power-frequency voltage is isolated by gap, protector does not bear lasting power frequency continued flow, be in " rest " state, guarantee the normal operation of electric power system, the utility model is by the first ball discharge, second ball discharge and lightning arrester are directly integrally, ensure that ball sphere gap distance is fixing, discharge stability.
During installation; must not divest the insulating barrier of insulated cable; thus eliminate the shortcoming of zinc oxide surge arresters; stop rainwater along insulating stripping except a plain conductor for infiltration etching insulative cable; safe and reliable to operation, non-maintaining; line overvoltage protection device, because there being series connection sphere gap isolation features, so can not cause short circuit grounding, guarantees the safety of electric power system.Line lighting protection overvoltage protector, can system power-frequency voltage moment power frequency continued flow effectively after lightning voltage in discharge process, avoids insulated conductor generation lightning-caused breaking accident.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technical scheme described in previous embodiment, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment technical scheme of the utility model.
