Abstract

A kind of without base lightning arrester, it comprises lightning arrester main body, insulation board and ground connection body, it is characterized in that: the lower end of lightning arrester main body is provided with insulation board, is provided with the ground connection body of stretching out lightning arrester main body in insulation board.The utility model is owing to being provided with insulation board in the lower end of lightning arrester main body, and be provided with the ground connection body of stretching out lightning arrester main flange in insulation board, ground connection body is connected with monitor.Save lightning arrester porcelain insulating base, the utility model does not affect by weather conditions, lightweight, is beneficial to installation and transportation, simultaneously cost-saving.

Description

Without base lightning arrester
Technical field
The utility model relates to power transformation or distribution technique field, particularly a kind of bottomless lightning arrester protecting high voltage power transmission and transforming equipment.
Background technology
Lightning arrester is the equipment that transforming plant protecting device exempts from lightning surge attack; when the lightning surge importing transformer station along circuit into exceedes protection of arrester level; first lightning arrester discharges; and by the introducing the earth of lightning current through good conductor safety; earthing device is utilized to make lightning voltage amplitude be limited in protected equipment lightning impulse below horizontal; make electric equipment make to be protected, the effect of lightning arrester is used to protect the electrical equipment that in electric power system, various electric equipment impacts from lightning overvoltage, switching overvoltage, Frequency Transient Overvoltage and damages.The type of lightning arrester mainly contains portable protective gaps, valve-type arrester and zinc oxide arrester.Portable protective gaps is mainly used in limiting atmospheric over-voltage, is generally used for distribution system, circuit and inlet wire of substation segment protect.Valve-type arrester and zinc oxide arrester are used for the protection in electric substation and power plant, be mainly used in limiting atmospheric over-voltage at 500KV and following system, also limit internal overvoltage by being used for or doing the backup protection of internal overvoltage in extra high voltage system, protection high voltage power transmission and transforming equipment lightning arrester, the lightning arrester that conventional structure is is that the additional porcelain insulating base of body is to meet lightning arrester insulation requirement; Its complex structure, cost are high, and base external insulation is serious in external insulation decline in rainy season.
Description
The purpose of this utility model is to provide the bottomless lightning arrester that a kind of structure is simple, lightweight, good insulating effect, cost are low.
The utility model is achieved in that it comprises lightning arrester main body, insulation board and ground connection body, it is characterized in that: the lower end of lightning arrester main body is provided with insulation board, is provided with the ground connection body of stretching out lightning arrester main body in insulation board.
The utility model is owing to being provided with insulation board in the lower end of lightning arrester main body, and be provided with the ground connection body of stretching out lightning arrester main flange in insulation board, ground connection body is connected with monitor.Save lightning arrester porcelain insulating base, the utility model does not affect by weather conditions, lightweight, is beneficial to installation and transportation, simultaneously cost-saving.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is the structural representation without base lightning arrester.
Embodiment
As shown in Figure 1, this bottomless lightning arrester comprises lightning arrester main body 1, insulation board 2 and ground connection body 3, and the lower end of lightning arrester main body 1 is provided with insulation board 2, is provided with the ground connection body 3 of stretching out lightning arrester main body 1 in insulation board 2.
