Abstract
The utility model discloses a lightning arrester test base, which is composed of a metal box body, externally arranged bolts and built-in nuts, wherein three bolts are welded at the center line of the upper end face of the open-type rectangular metal box body, a grounding bolt is welded at the lower right corner of the upper end face, the center lines of the front side surface and the opposite surface thereof of the metal box body are both provided with three round holes, a nut is welded in each of the round hole, and the left and right end faces of the rectangular metal box are transparent and not blocked. According to the utility model, three thin-screw lightning arresters, thick-screw lightning arresters or lightning arresters with undetachable screws can be placed on the lightning arrester test base, thereby being convenient for operations, and improving the efficiency and the test safety and reliability.
Description
Technical field
The utility model relates to a kind of electric power overhaul power tool, particularly the test of lightning arrester base of a kind of 10kV test of lightning arrester operation.
Background technology
In electric system, it is very general that lightning arrester is used, lightning arrester is avoided the superpotential infringement for protection transmission of electricity, converting equipment and subscriber equipment and is played vital effect, in the preventive trial in every year, all to carry out the test of withstand voltage and Leakage Current to lightning arrester, with the check lightning arrester well whether; Because the difficult tree of 10kV lightning arrester is directly put vertical unique model, test of lightning arrester does not allow lightning arrester to lie down the requirement of carrying out in addition, and test of lightning arrester is all only to be completed one by one by single usually, and efficient is relatively low; Lightning arrester belongs to consumables, and preventive trial will be tested all lightning arresters, also will test to new lightning arrester when occurring damaging at ordinary times, and test number (TN) is quite frequent, workload is large; The test site of suiting measures to local conditions at the trial to seek can impact job schedule, and reduces safe reliability, up to the present, also is not specifically designed to when doing experiment, and puts the specific purpose tool type equipment of lightning arrester.
The utility model designs according to the actual tests needs of 10kV lightning arrester, solve lightning arrester be difficult for upright, the problem that test efficiency is low, this test base volume is little, be convenient to loading and unloading.
The utility model content
The purpose of this utility model is to provide the test of lightning arrester base of a kind of 10kV of convenience test of lightning arrester operation.
in order to achieve the above object, technical solution of the present utility model is: a kind of test of lightning arrester base, it comprises metal cabinet, external bolt and built-in nut, on the upper surface center line of open-type rectangle metal cabinet, equidistantly weld 3 bolts, at 1 earth stud of the lower right corner of upper surface welding, the center line equal intervals is opened 3 circular holes in the positive side of rectangle metal cabinet, nut B of place, inboard welding of each circular hole, on the corresponding surface center line of the positive side of described metal cabinet, also equidistantly open 3 circular holes, nut A of place, inboard welding of each circular hole.
Spacing between 3 bolts is 200mm, is 100mm apart from the distance of the right and left; Earth stud is all 25mm apart from the distance of the long limit of metal cabinet and minor face.
Spacing between nut A is 200mm, is 100mm apart from the distance of the right and left, and the spacing between nut B is 200mm, is 100mm apart from the distance of the right and left.
The left and right both ends of the surface of open-type rectangle metal cabinet are penetrating unobstructed.
Due to can place 3 micro screw lightning arresters on the test of lightning arrester base, thick screw rod lightning arrester maybe can't be pulled down the lightning arrester of screw rod, has facilitated operation, has improved test efficiency and safe reliability.
Description of drawings
Fig. 1 is test of lightning arrester understructure schematic diagram;
In the drawings, 1-metal cabinet, 2-bolt, 3-earth stud, 4-nut A, 5-nut B.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model, structure are described in further detail.
As shown in Figure 1, the test of lightning arrester base is constituted by metal cabinet, external bolt and built-in nut, on the upper surface center line of the rectangle metal cabinet 1 of open-type, equidistantly weld 3 bolts 2, be used for laying lightning arrester, bolt 2 can be selected Φ 10 * 50mm model, and the spacing between bolt 2 is 200mm, is 100mm apart from the distance of the right and left; 1 earth stud 3 of lower right corner welding in the casing upper surface, being used for implementing lightning arrester base is connected with ground wire, realize the reliable ground of lightning arrester base and lightning arrester, earth stud 3 can be selected Φ 10 * 25mm model, earth stud 3 is 25mm apart from the distance on the long limit of metal cabinet, is also 25mm apart from the distance of minor face.
On the center line of the positive side of rectangle metal cabinet 1, equidistantly open 3 circular holes, at nut B of the box inside place of each circular hole welding, nut B can select Φ 10mm model, and the spacing between nut B is 200mm, is 100mm apart from the distance of the right and left; On the corresponding surface center line of metal cabinet 1 positive side, also equidistantly open 3 circular holes, nut A of place, the inboard of each circular hole welding, nut A can select Φ 12mm model, and the spacing between nut A is 200mm, is 100mm apart from the distance of the right and left.
Two of the left and right of open-type rectangle metal cabinet 1 end face is all penetrating unobstructed, the installation and removal of lightning arrester when conveniently doing experiment.
Make test of lightning arrester base metal cabinet, can select thick 2mm stainless steel materials processing, also can select other metal material, casing is of a size of: 600 * 200 * 200mm.
