Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage testing, in particular to a portable and foldable pressure-resistant auxiliary device. Background Art

[0002] High-voltage test equipment has very strict requirements for the site when conducting high-voltage tests. The most important requirement is that the site space is large enough, otherwise the withstand voltage will discharge to the ground, resulting in inaccurate data, equipment damage, and even personal safety accidents. Series resonance is a circuit property and also a series resonance test device. However, series resonance is composed of an operating box, a variable frequency power supply, an excitation transformer, a high-voltage reactor, and a capacitive voltage divider. Each piece of equipment is relatively large and cannot be safely placed behind the high-voltage cabinet for routine operation experiments. At present, the distance between the high-voltage cabinet and the rear wall of some high-voltage substations in China can only meet normal production requirements, but the test equipment cannot be placed normally, which causes great difficulties for the test. Utility Model Content

[0003] The utility model aims to solve the above-mentioned problem, thereby providing a portable and foldable pressure-resistant auxiliary device capable of meeting the test requirements when the distance between the high-voltage cabinet and the rear wall is small.

[0004] The utility model solves the above problems and adopts the following technical solutions:

[0005] A portable and foldable pressure-resistant auxiliary device comprises brackets arranged on both sides of a high-voltage cabinet, upper connecting posts are arranged at the top of the brackets, wires are arranged between the upper connecting posts, and a grounding wire post is arranged at the bottom of the brackets.

[0006] Compared with the prior art, the utility model adopting the above technical solution has the following outstanding features:

[0007] During the test, the two brackets are placed on both sides of the high-voltage cabinet in open spaces that meet the conditions. The top of the bracket is connected to the upper terminal through a long wire. At the same time, the test equipment can be placed in any safe and appropriate position. After the equipment is placed, the high-voltage side of the test equipment is connected to the upper terminal, and the low-voltage side is connected to the grounding terminal. During the test, you only need to connect the tested product to the wire to complete the test, which perfectly solves the problem of insufficient space for test equipment.

[0008] As a preferred embodiment, a further technical solution of the utility model is:

[0009] The bracket includes a telescopic rod at the upper part and a retractable tripod at the lower part.

[0010] The telescopic rod is made of insulating material. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a schematic diagram of the structure of an embodiment of the utility model;

[0012] The markings in the figure are: telescopic rod 1, retractable tripod 2, upper terminal 3, wire 4, and high-voltage cable to be tested 5. DETAILED DESCRIPTION

[0013] The present invention is further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0014] A portable and foldable voltage-resistant auxiliary device comprises a bracket arranged on both sides of a high-voltage cabinet, an upper terminal 3 is arranged at the top of the bracket, a wire 4 is arranged between the upper terminal 3, a grounding terminal is arranged at the bottom of the bracket, and the grounding terminal is grounded. Placing the bracket on both sides of the high-voltage cabinet solves the problem of insufficient space, and the high-voltage cable 5 to be tested is connected to the wire. The high-voltage side of the test equipment is connected to the upper terminal 3, and the low-voltage side is connected to the grounding terminal.

[0015] The bracket comprises an upper telescopic rod 1 and a lower retractable tripod 2. The height can be adjusted by the telescopic rod 1, so as to be convenient for coping with high-voltage cabinets of various heights, and the retractable tripod 2 is convenient for storage.

[0016] The telescopic rod is made of insulating material.

[0017] During the test, the two brackets are placed in the open spaces on both sides of the high-voltage cabinet where the conditions are met. The top of the bracket is connected to the upper terminal 3 through a long wire. At the same time, the test equipment can be placed in any safe and suitable position. After the equipment is placed, the high-voltage side of the test equipment is connected to the upper terminal 3, and the low-voltage side is connected to the grounding terminal. During the test, it is only necessary to connect the tested product to the wire to complete the test, which perfectly solves the problem of insufficient space for the test equipment and the disadvantage of being unable to test in a small space. At the same time, it can greatly improve safety and ensure the safety of equipment and personnel. Through the experimental device, the output end of the series resonance can be connected to the upper terminal, and the entire set of series resonance equipment can be placed in a safe and reliable environment for experimentation, thereby ensuring the personal safety of the operator; at the same time, the test equipment no longer needs to be carried back and forth, which improves efficiency.
