Abstract
A lightning arrester combined support of a single-column transformer platform comprises a straight steel lath, an earth wire contact is arranged in center of the straight steel lath, and one end of the straight steel lath is connected with an installing straight lath vertical with the straight steel lath; three connecting circular holes used for installing lightning arresters are arranged on the installing straight lath, the other end of the straight steel lath is connected with a forked plate, and each branch fork of the forked plate is equipped with an installing circular hole arranged on a bolt of a transformer upper cover. According to the utility model, one end of the straight steel lath is connected with the installing straight lath vertical with the straight steel lath, three lightning arresters can be arranged on the installing straight lath, and the forked plate is connected with the other end of the straight steel lath and can be arranged on the adjacent bolts of the transformer upper cover; after the lightning arresters are arranged and when the lightning arresters are used, the distances between the lightning arresters and the equipment on the transformer platform and the distances among the lightning arresters accord with the electricity safety distances; and after the connecting circular holes on the forked plate are connected on the adjacent bolts of the transformer upper cover, and because of a multi-point connection mode, the lightning arrester combined support of the single-column transformer platform does not swing left and right after being applied forces.
Description
Technical field
The utility model relates to a kind of support of using when transformer platform is installed lightning arrester, particularly a kind of support of using when the single-column transformer platform is installed lightning arrester.
Background technology
High-pressure side on transformer platform need be installed lightning arrester, three-phase electricity on the transformer platform need be installed three lightning arresters, lightning arrester is installed on the bolt of transformer loam cake by support, lightning arrester is installed the back with in use, and the distance of the equipment on the distance between the lightning arrester and lightning arrester and the transformer platform will meet the requirement of Electrical Safety distance.
In the prior art, the support of using at single-column transformer installation lightning arrester is straight steel plate bar, three lightning arresters need the support of three straight steel plate bars conduct, there is the ground wire contact centre of the straight steel plate bar of surge arrester support, the length of straight steel plate bar meet the equipment on lightning arrester and the transformer platform safe distance requirement, the both sides of straight steel plate bar have circular hole respectively, and a mother rib lateral rotundum is that the opposite side circular hole is be used to the installation circular hole on the bolt that is installed in the transformer loam cake for the connection circular hole that lightning arrester is installed.During use, the installation circular hole of the straight steel plate bar of surge arrester support is connected on the bolt of transformer loam cake, lightning arrester is connected on the connection circular hole, connect ground wire at the ground wire contact.
This surge arrester support is because be three straight steel plate bars, be installed on the bolt of transformer loam cake after, be a bit fixing, straight steel plate bar swings when stressed easily.Straight steel plate bar swings and can cause the bolt looseness of transformer loam cake, and the bolt looseness of transformer loam cake can destroy the sealing of transformer; The distance that also can cause distance between the lightning arrester and the equipment on lightning arrester and the transformer platform of swinging straight steel plate bar departs from the requirement of Electrical Safety distance.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, the single-column transformer platform lightning arrester sectional shelf-unit that can not swing after proposing on a kind of bolt that is installed in the transformer loam cake.
The utility model is realized with the following method.
Single-column transformer platform lightning arrester sectional shelf-unit has straight steel plate bar, there is the ground wire contact centre of straight steel plate bar, one end of straight steel plate bar is connected with the installation straight board lath vertical with straight steel plate bar, install three connection circular holes that are used for installing lightning arrester are arranged on the straight board lath, the other end of straight steel plate bar is connected with the bifurcated plate, and each of bifurcated plate fork is useful on the installation circular hole on the bolt that is installed in the transformer loam cake respectively.
The length of the straight steel plate bar of the utility model can be the safe distance that meets the equipment on lightning arrester and the transformer platform, three on the installation straight board lath for the distance between the circular hole that lightning arrester is installed, can be the requirement that meets the Electrical Safety distance, the distance between the circular hole on the bolt that is installed in the transformer loam cake on the adjacent bifurcated plate be identical with the distance of the adjacent bolt of transformer loam cake.
During use, the installation circular hole on the bifurcated plate is connected on the adjacent bolt of transformer loam cake, three lightning arresters are connected in respectively on three connection circular holes installing on the straight board lath, connect ground wire at the ground wire contact.
One end of the straight steel plate bar of the utility model is connected with the installation straight board lath vertical with straight steel plate bar, installs on the straight board lath three lightning arresters can be installed, and the other end of straight steel plate bar is connected with the bifurcated plate, and the bifurcated plate can be installed on the adjacent bolt of transformer loam cake.When back and use are installed, can make the distance of distance between the lightning arrester and the equipment on lightning arrester and the transformer platform will meet the requirement of Electrical Safety distance, after installation circular hole on the bifurcated plate is connected on the adjacent bolt of transformer loam cake, because be that multiple spot connects, after the utility model was stressed, the utility model can not swing.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
Fig. 1 is that the master of a kind of single-column transformer platform lightning arrester sectional shelf-unit of proposing according to invention scheme of the present utility model looks schematic diagram;
Fig. 2 is the schematic top plan view of the utility model after being installed in transformer.
Embodiment
Among Fig. 1, it is the straight steel plate bar 1 of 200mm that single-column transformer platform lightning arrester sectional shelf-unit has width, there is ground wire contact 2 centre of straight steel plate bar, one end of straight steel plate bar is connected with the installation straight board lath 3 vertical with straight steel plate bar, install three connection circular holes 4,5,6 that are used for installing lightning arrester are arranged on the straight board lath, the other end of straight steel plate bar is connected with two each of pitching plates 7, two fork plates and pitches the installation circular hole 8,9 that is useful on respectively on the bolt that is installed in the transformer loam cake.
Among Fig. 2, circular hole is installed is connected on adjacent two bolts 11,12 of transformer 10 loam cakes for two on the two fork plates 7 of the present utility model.
