The invention discloses a discharge shielding protection device for a transformer. The discharge shielding protection device comprises a transversely inserted case and a shielding device, wherein an insulating protection plate is fixedly arranged on the inner surface of the transversely inserted case; the rear part of the insulating protection plate is connected with the inner wall of the transversely inserted case through a rubber gasket; an aluminum plate is also fixedly arranged on the lower surface of the insulating protection plate; an AC module placement groove is also arranged between the lower end of the aluminum plate and the transversely inserted case; power supply equipment is also arranged at the right end of the AC module placement groove; the AC module placement groove and the power supply equipment are arranged on the inner wall of the transversely inserted case; and the shielding device is also fixedly arranged on the upper surface of the insulating protection plate. Aninterference source is separated from a sensitive element through a shielding plate to form a shielding compartment, so that seams between the discharge shielding protection device and the the case are reduced to the greatest extent and reliable electric contact with the case is ensured; and metal shaft shielding devices are arranged on the surface of a case body, so that the influence of a metalbracket in the using process is shielded.
Description
technical field [0001] The invention relates to the technical field of discharge shielding protection devices, in particular to a discharge shielding protection device for transformers. Background technique [0002] With the development of the economy and the advancement of science and technology, people are using more and more transformers. At the same time, there are certain hidden safety hazards that need to be dealt with during the use of transformers. At present, there are still some protection devices for transformer leakage shielding. Defects: [0003] (1) The existing shielding protection devices for transformer discharge need to use metal objects as brackets to provide support during use, but when metal objects pass through the shield, the antenna effect will cause the shield to Leakage, so the metal body cannot directly pass through the shield, which limits the use of the transformer; [0004] (2) There are two main types of existing transformer leakage methods: ...
