Abstract
A 35kV outdoor alternating current three phase combination type lightning arrester comprises five single 35kV lightning arresters. Lower portions of the three single 35kV lightning arresters are connected with an upper surface of a plate-shaped support steel plate. And the three single 35kV lightning arresters are uniformly distributed on the upper surface of the support steel plate. Upper portions of the other two 35kV lightning arresters are connected with a lower surface of the support steel plate. The lower portions of the other two 35kV lightning arresters are contacted with a corresponding discharge counter or a corresponding on-line monitor respectively. The single 35kV lightning arrester only has phase-to-ground protection and does not have an overvoltage protection capability between phases. Installation of the single 35kV lightning arrester is not convenient for positions with limited spaces. External insulation performance of the single 35kV lightning arrester is limited so that flashover risks exist in the external insulation. By using the lightning arrester of the utility model, the above defects can be effectively avoided.
Description
Technical field
The utility model belongs to 35kV outdoor substation protection equipment for transformer technical field, is specifically related to the three phase combined lightning arrester of a kind of 35kV outdoor AC, also can be as 35kV outdoor AC three phase combined over-voltage protector.
Background technology
The 35kV outdoor substation lightning arrester of China's use at present, all adopt single use, increasing at electric load, power supply quality requires more and more higher, power supply reliability requires under the more and more tighter situation, the use of single lightning arrester comes with some shortcomings, particularly in the mine, special field of employment such as oil field, hospital, its existence not enough specific as follows:
1, single 35kV lightning arrester only has a ground protection, does not have the overvoltage protection ability between an item;
2, single 35kV lightning arrester is installed and is taken up room greatly, for limited place, some locus,
Install very inconvenient;
3, the external insulation performance of single 35kV lightning arrester is limited, and for phenomenons such as special weather such as mist, dusts, there is certain flashover danger in external insulation.
Summary of the invention
The purpose of this utility model provides a kind of 35kV outdoor AC three phase combined lightning arrester, comprise the 35kV lightning arrester that five lists prop up, wherein the bottom of the 35kV lightning arrester that props up of three lists is connected with the upper surface of tabular supporting steel plate, and the 35kV lightning arrester that these three lists prop up is the uniform state distribution at the upper surface of supporting steel plate, and the top of two other 35kV lightning arrester of single is connected with the lower surface of supporting steel plate, and the bottom of described two other 35kV lightning arrester of single all contacts with each self-corresponding discharge counter or on-line monitoring device.Avoided single 35kV lightning arrester that a ground protection is only arranged effectively and do not have between overvoltage protection ability, single 35kV lightning arrester install and for limited place, some locus the limited external insulation that makes of external insulation performance very inconvenient and single 35kV lightning arrester be installed and had certain flashover dangerous defects.
In order to overcome deficiency of the prior art, the utility model provides the solution of the three phase combined lightning arrester of a kind of 35kV outdoor AC, and is specific as follows:
The three phase combined lightning arrester of a kind of 35kV outdoor AC, comprise the 35kV lightning arrester 1 that five lists prop up, wherein the bottom of the 35kV lightning arrester 1 that props up of three lists is connected with the upper surface of tabular supporting steel plate 2, and the 35kV lightning arrester 1 that these three lists prop up is the uniform state distribution at the upper surface of supporting steel plate 2, and the top of two other 35kV lightning arrester 1 of single is connected with the lower surface of supporting steel plate 2, and the bottom of described two other 35kV lightning arrester 1 of single all contacts with each self-corresponding discharge counter or on-line monitoring device 3.
The bottom of described two other 35kV lightning arrester 1 of single all same tabular installation steel plate 4 is connected.
Use the utility model such scheme; there are not the overvoltage protection ability between an item, single 35kV lightning arrester installation for limited place, some locus the limited external insulation that makes of external insulation performance very inconvenient and single 35kV lightning arrester to be installed and to be had certain flashover dangerous defects except having avoided single 35kV lightning arrester that the protection of item ground is only arranged; and this utility model still is a kind of simple in structure, easy for installation and outdoor combined arrester that the overvoltage protection performance is superior, and this utility model also has following advantage in addition:
Protective capability between also having when 1, having protective effect between phase ground;
2, for any one superpotential protection process, all be to be finished jointly by two single lightning arresters,
Therefore the external insulation performance of product is original two times, increases product for the adaptation of extreme weather phenomenon.
3, product also is applicable to the protection of capacitor group simultaneously;
4, at places such as smelting, mines, can also adopt inner band gap structure.
