The two ends of the copper bar pass through the left and right side walls of the box body respectively. , set grounding terminals at both ends of the copper bar. The utility model can not only make the wiring process of the 10kV lightning arrester test more convenient and fast, reduce the work intensity of the operators, but also enhance the safety of the test and improve the test work efficiency.

Description

A lightning arrester test frame

technical field

The utility model relates to a test frame, in particular to a lightning arrester test frame, which belongs to the technical field of testing. the

Background technique

Most of the 10kV surge arresters (as shown in Figure 1) are in bulk. Due to their small size and the connection studs 1-1 are arranged at both ends of the upper and lower ends of the arrester. Without a reliable placement bracket, not only is it easy to cause the 10kV surge arrester 1 to fall, making it difficult to carry out the test work smoothly, but it also brings potential safety hazards to the construction site. the

Utility model content

The purpose of the utility model is to provide a lightning arrester test frame with simple structure, convenient use and reliable placement of the tested lightning arrester in order to meet the test requirements of the 10kV lightning arrester. the

Problem described in the utility model is realized with following technical scheme:

A lightning arrester test frame, which includes a box body and a copper bar, a set of lightning arrester installation holes are arranged on the top surface of the box body, the copper bar is installed in the inner cavity of the box, and the two ends of the copper bar are separated from the left side of the box body. , The right side wall passes through, and grounding terminals are set at both ends of the copper bar.

In the above arrester test frame, the box is a rectangular box structure, the number of arrester installation holes on the top surface of the box is not less than two, and a set of vertical support plates and horizontal reinforcement plates are arranged in the inner cavity of the box. the

In the above lightning arrester test frame, a group of lightning arrester connecting holes is provided on the copper bar, and the number of the lightning arrester connecting holes matches the number of lightning arrester installation holes on the top surface of the box body. the

The utility model adopts the insulation board material to make the box body, and the lightning arrester installation hole is set on the top surface of the box body, and the lightning arrester can be directly placed on it and fixed during the test; the utility model is connected with the lightning arrester through the copper bar in the inner cavity of the box , and set grounding terminals at both ends of the copper bar to make the grounding of the arrester more reliable. The on-site trial of the 10kV surge arrester test stand proves that it not only makes the wiring process easier and faster, reduces the work intensity of the operator, but also enhances the safety of the test and improves the test work efficiency. the

Fig. 4 is a schematic diagram of the working state of the utility model.

The list of labels in the figure is: 1. 10kV surge arrester, 1-1, connecting stud, 2. Box body, 2-1, installation hole of surge arrester, 2-2, vertical support plate, 2-3, horizontal reinforcement plate, 3. Copper bar, 3-1. Arrester connection hole, 4. Grounding terminal. the

Detailed ways

Referring to Figure 1, the 10kV arrester 1 has a small size, and connecting studs 1-1 are arranged at both ends of it. When testing the 10KV arrester 1 at the construction site, a reliable placement bracket must be provided. the

Referring to Fig. 2 and Fig. 3, the utility model includes a box body 2 and a copper bar 3, the box body 2 is a rectangular box body structure, and a group of not less than two lightning arresters are installed on the top surface of the box body 2 Holes 2-1, a group of vertical support plates 2-2 and horizontal reinforcement plates 2-3 are arranged in the box cavity. The copper bar 3 is installed in the inner cavity of the box, and the two ends of the copper bar 3 respectively pass through the left and right side walls of the box body, and the two ends of the copper bar 3 are provided with grounding terminals 4, and the copper bar 3 is also provided with a A group of lightning arrester connecting holes 3-1, the number of said lightning arrester connecting holes 3-1 matches the number of lightning arrester installation holes 2-1 on the top surface of the box body. . the

Referring to Fig. 4, before testing the 10kV arrester 1 in the utility model, the 10KV arrester 1 can be directly placed in the arrester mounting hole 2-1 on the top surface of the box body 2, and the lower end of the arrester is connected to the stud connected to the copper bar. After the hole is assembled and fixed; the arrester is reliably grounded through the grounding terminal of the copper bar, and then connected to the wire of the test instrument through the connecting stud at the upper end of the 10KV arrester 1. After the above steps are completed, the test can be carried out according to the test requirements. the
