Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a withstand voltage tester for transformers. Background Art

[0002] An electronic transformer is an electronic device that converts the alternating voltage of the commercial power into direct current and then forms a high-frequency alternating voltage output through semiconductor switching devices, electronic components and high-frequency transformer windings. It is mainly composed of a high-frequency transformer core (iron core) and two or more coils. Through the action of electromagnetic induction with alternating current, it is transformed into alternating voltage and current. At present, during the production process of electronic transformers, it is necessary to perform a withstand voltage test on the electronic transformers.

[0003] In the Chinese patent with the publication number CN 220271474 U, a withstand voltage tester for an electronic transformer is disclosed, which includes a tester; connection blocks are threadedly connected to the threaded parts at both ends of a double-headed screw rod. Fixed blocks are installed on both sides of the double-headed screw rod, and two hinge seats are installed on each fixed block. Hinge plates are hinged between the two ends of the connection block and the hinge seats. Clamping plates for clamping the electronic transformer are installed on the outer walls of the fixed blocks; when the plurality of double-headed screw rods rotate, under the traction of the connection blocks, the clamping plates on both sides move towards both sides, and then the electronic transformer can be clamped in the fixed groove. Under the action of the clamping plates, the electronic transformer will not shake or fall, etc., thus ensuring the stability and safety during the withstand voltage test of the electronic transformer; through the restriction of the electronic transformer, this design can stably fix the electronic transformer and ensure the smooth progress of the withstand voltage test of the electronic transformer.
