Description

Technical Field

[0001] The utility model relates to a withstand voltage test fixture, and relates to the technical field of transformer withstand voltage test fixtures, in particular to an automatic withstand voltage test fixture for transformers. Background Art

[0002] The utility model verifies whether the insulation of the transformer is qualified. It is generally composed of a motor, a screw rod, a push block, a bakelite strip, conductive cotton, a copper sheet, a cargo platform, a bakelite bottom plate, etc. The product undergoes a withstand voltage test to ensure that the product insulation characteristics meet the requirements and prevent the product from being short-circuited and sent to customers to cause adverse losses. The current withstand voltage test process requires testing the insulation between the primary coil and the secondary coil. The current test is mostly a cylinder control test, which requires gas and electricity to provide power at the same time and has large usage restrictions.

[0003] Therefore, in view of the existing problems in the prior art, it is particularly important to provide a new type of withstand voltage test fixture. Utility Model Content

[0004] The purpose of the utility model is to provide a novel withstand voltage test fixture to solve the problems raised in the above background.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A new type of withstand voltage test fixture is powered by a motor to push the conductive cotton and press the copper sheet to contact the product pin for testing, thus forming the main part of the test fixture.

[0007] Preferably, the fixture is placed on a loading platform to fix the product and is controlled by a motor to contact and perform testing.

[0008] Preferably, the fixture is powered by a motor to make the copper sheet and the conductive cotton contact the product pins and perform the contact test. The copper sheet and the probe are respectively connected to the high-voltage and low-voltage output stages of the withstand voltage tester to achieve the test purpose.

[0009] Beneficial effects of the utility model:

[0010] Compared with the existing pressure test fixture powered by a cylinder, the utility model has the beneficial effect of being a fixture with low energy consumption and high precision. It has a simple structure and is easy to operate, ensuring that the action is in place, improving the efficiency of the pressure test, and reducing production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention is further described with reference to the accompanying drawings, but the contents in the accompanying drawings do not constitute any limitation to the present invention.

[0012] Figure 1 The utility model is a plan view of a novel withstand voltage test fixture.

[0013] Legend: (1) reset switch, (2) bakelite strip, (3) loading platform, (4) test switch, (5) screw rod, (6) motor, (7) copper sheet, (8) conductive cotton, (9) push block, (10) bakelite base plate. DETAILED DESCRIPTION

[0014] The utility model is further described in conjunction with the following embodiments.

[0015] Reference Figure 1 The utility model provides an embodiment: a novel withstand voltage test fixture, comprising: (1) a reset switch, (2) a bakelite strip, (3) a loading platform, (4) a test switch, (5) a screw rod, (6) a motor, (7) a copper sheet, (8) a conductive cotton, (9) a push block, and (10) a bakelite bottom plate. When in use, the product is placed on the loading platform, and the switch is pressed to start the motor, that is, the motor rotates forward, the screw rod moves forward, and the push block makes the pins on one side of the loading platform contact with the conductive cotton, and the bakelite strip copper sheet contacts with the pins on the other side. At the same time, the push block triggers the test switch, and the test starts. When the test is completed, the reset button is pressed, the motor reverses and resets, the screw rod retreats to take out the product, and the next product test is carried out.

[0016] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not intended to limit the scope of protection of the claims. Ordinary technicians in the field should understand and modify the technical solution of the utility model by referring to the preferred embodiments, but they can still be equivalent to the technical solution of the utility model and its protection scope.
