Description

Technical Field

[0001] The utility model relates to the technical field of transformer maintenance technology, in particular to a large current bushing test vehicle. Background Art

[0002] Because some tests of high current bushings require that the metal part at the lower end be submerged in transformer oil, in the past, channel steel was generally used to place the bushing on a metal barrel. In order to prevent the bushing from falling, a crane was needed to hang the bushing, which was not standardized and had certain safety hazards. In order to standardize the corresponding bushing tests, it is necessary to design a special test trolley that is oil-resistant, has an oil discharge and injection valve, and can bear, fix, and move high current bushings. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a high-current bushing test vehicle, which can test and transport the high-current bushing.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a high-current bushing test vehicle, including a base, a groove for placing the high-current bushing is provided in the middle of the base, a universal wheel is provided at the bottom of the base, and a top cover is provided on the base to cover the high-current bushing.

[0005] Preferably, an annular platform is provided at the edge of the upper end of the base, and the top cover is provided on the annular platform; a lock buckle for fixing the top cover is also included.

[0006] Preferably, the upper portion of the groove is connected to a liquid inlet pipe, and the bottom portion is connected to a liquid discharge pipe, and valves are provided on the liquid inlet pipe and the liquid discharge pipe.

[0007] Preferably, a sealing rubber ring is provided at the bottom of the top cover.

[0008] Preferably, a push rod is provided on one side of the base.

[0009] The utility model provides a high current bushing test vehicle, which has the following beneficial effects:

[0010] (1) It standardizes bushing testing, reduces operational risks, avoids waste of insulating oil, improves operational efficiency, and eliminates safety hazards in the entire testing process.

[0011] (2) During the test, no other protection is required and the casing will not fall. When the test is terminated, only the outer cover needs to be installed to ensure that the casing is not damaged or damp. If it rains or the relevant test is postponed, the casing can be moved to a safe location at any time by a trolley.

[0012] (3) The vehicle not only successfully solves the safety problem of high-current bushing testing, but also meets the technical requirements for bushing oil filling storage. It is a dual-purpose vehicle, making bushing testing safer, more efficient and convenient. BRIEF DESCRIPTION OF THE DRAWINGS
