Abstract

The utility model relates to an experimental special strutting arrangement of withstand voltage, it includes landing leg and bracing piece, the bottom swing joint of connecting rod and bracing piece is passed through at the middle part of landing leg, and cup joint through sliding sleeve and bracing piece slip on the top of landing leg, the top of bracing piece is equipped with the fixing base, one side of fixing base is equipped with the L type fixed head that is used for fixed high tension lead. The function of supplementary high -voltage testing line has been realized to the L type fixed head at the bracing piece cooperation top that can insulate in the middle part, and it is nearer to prevent that the high -voltage testing linear distance from being tried the article casing, and easily the flashover causes the emergence of the condition such as instrument tripping operation, experimental unusual interrupt, the bottom is adopted collapsible four corners to support and is processed into the base, stable in structure, can take in, the middle part insulator spindle can take multiple butt joint scheme according to on -the -spot different situation for the dock, can lengthen the height, can adapt to the not co -altitude of field test needs, top design has the L type fixed head of fixed high tension lead for support the high tension lead.

Description

Special support device for insulation withstand voltage test

technical field

The utility model belongs to the technical field of special support tools for insulation withstand voltage tests, and is applied to insulation withstand voltage tests for electrical equipment.

Background technique

In the prior art, with the increase of electrical equipment, the insulation supervision and testing work is becoming more and more important. As the most critical item of electrical testing: the insulation withstand voltage test item is becoming more and more important in the insulation supervision and testing site; the insulation withstand voltage test is The most effective and direct method to identify the insulation strength of power equipment; during the operation of power equipment, the insulation will gradually deteriorate and form defects under the action of electric field, temperature, humidity and mechanical vibration for a long time; various preventive test methods have their own advantages, Some defects can be found respectively, reflecting the condition of the insulation, but the test voltage is far lower than the working voltage of the equipment, which is not enough to guarantee the safe operation. The insulation withstand voltage test is in line with the electrical conditions that the power equipment is subjected to during operation. The test voltage is much higher than the operating voltage. After passing the test, the equipment has a large safety margin; at the same time, excessive voltage will increase the loss of the insulation medium, Heat generation and discharge will accelerate the aging and development of the insulating medium, so the insulation withstand voltage test is a destructive test. At present, the insulation withstand voltage test used is composed of test transformers and high-voltage leads. During the long-term test, it was found that the wiring time of the high-voltage leads is too long; Problems such as abnormal interruption of the test have seriously affected the normal development of the test work.

Contents of the invention

The purpose of the utility model is to solve the technical problems of the prior art that the leads are too long and easy to flashover, and provide a special supporting device for the insulation withstand voltage test to overcome the deficiencies of the prior art.

In order to achieve the above object, the utility model is a special support device for insulation and voltage test, the main point of which is that it includes a leg and a support rod; the middle part of the leg is movably connected with the bottom end of the support rod through a connecting rod, and the leg The top of the support rod is slidingly socketed with the support rod through a sliding sleeve; the top of the support rod is provided with a fixed seat; one side of the fixed seat is provided with an L-shaped fixed head for fixing the high-voltage lead wire.

The utility model has a reasonable structure and is easy to use. The insulated support rod in the middle cooperates with the L-shaped fixed head on the top to realize the function of assisting the high-voltage test line, and prevent the high-voltage test line from being close to the shell of the tested product, which is easy to flashover and cause the instrument In the event of tripping or abnormal interruption of the test, etc.; the new type of special support tool for the insulation and voltage withstand test has a reasonable structure design, simple and convenient operation, and a uniform and beautiful design, which is conducive to the implementation of on-site standardized operations; the bottom is processed into a base with retractable four-corner supports. The structure is stable, it can be stored, and the middle insulation rod is a docking type. Various docking schemes can be adopted according to different situations on site. Supports high voltage leads.
