dga test of transformer oil transformer test recurrent surge oscillograph

 Product overview:

When doing single set AC test with YDC port type test transformer, it needs to insert short pole (can also insert cascade tapping wiring pole), when doing DC test, it needs pulling out the short circuit pole and cascade tapping wiring pole; When used for cascade HV test, it needs inserting the short circuit pole and cascade wiring pole at the same time (Transformer cover with C mark is cascade taping wiring pole, and D mark is short circuit pole.
When doing DC voltage endurance or DC leakage test with YD port transformer, pull out the short circuit pole; When doing AC HV test, insert short circuit pole.

Products features:

1.Inflatable test transformer,compared with the traditional oil-immersed test transformer, the weight is reduced by 20%-60%, and the material selection and process flow are all new. Therefore,it is not only small in size,light in weight, beautiful in appearance, but also has various technical indicators that meet the requirements of <<JB3570-98>>. The high-quality cold-rolled DQ-151 oriented silicon steel sheets are stacked into a multi-stage cylindrical frame-shaped iron core, and the high-voltage tower coil is directly and continuously wound by a QZ-type wire on a special high-strength insulation cylinder. The outer casing is of a conformable size and is filled with SF6 gas. The difference in the product is that the high-voltage rectifying silicon stack can be transformed into the high-voltage sleeve by the insertion and extraction of the short-circuiting rod.

2.dry test transformer, is the introduction of the latest foreign advanced technology, the use of advanced production equipment, the use of coil epoxy vacuum casting, and CD-type iron core new technology, new materials. Compared with the oil immersed test transformer of the same capacity and the same voltage level, it has the advantages of light weight, small size, beautiful appearance, convenient use and carrying, and the like. And effectively weaken the magnetic flux leakage to improve the insulation strength and moisture resistance.

3.The oil-immersed test transformer is produced according to the "test transformer" standard of the Ministry of Electrical and Mechanical Engineering and has been extensively improved on the basis of the original similar products. It adopts a single-frame core type iron core structure. The primary winding is placed on the core and the high voltage winding is external. This coaxial arrangement reduces the leakage flux and thus increases the coupling between the windings. The outer shell of the product is made of a better octagonal structure with the core, and the overall shape looks beautiful.3.The oil-immersed test transformer is produced according to the "test transformer" standard of the Ministry of Electrical and Mechanical Engineering and has been extensively improved on the basis of the original similar products.

4.The transformer control box is the supporting equipment for the test transformer. Its superior performance, multi-function, small size, light weight, reliable use, beautiful appearance, convenient operation and maintenance. The control box is box-type or desktop structure, the box type is aluminum alloy box, the table top is iron shell spray, all electrical components are mounted on the skeleton for easy installation and maintenance.
