Problems solved by technology

[0002] At present, most of the vehicle transformers use simple normal pressure oil injection method. Due to the compact internal structure of the transformer, the vacuum degree in the transformer and the complete infiltration of transformer oil into various parts of the transformer cannot be guaranteed, resulting in many problems in the operation of the transformer. To a certain extent, it affects the high performance and life of the silicone oil transformer

Abstract

The invention discloses a silicon oil transformer oil injection process and its device. The upper and lower valves of the transformer (1) are connected with a silicon oil treatment system (2) and a vacuum system (3) through a three-way pipe, and the expander of the transformer (1) is connected with a heating The static pressure system (4), the PLC circuit control box (5) is electrically connected with the static pressure system (4) and the vacuum system (3). The invention can ensure the various coefficients of the silicone oil injected into the transformer at the same time as the silicone oil is injected, reduces the probability of various failures of the transformer, and reduces various costs caused by the rework of the transformer. It is a simple, convenient, The silicone oil injection method is safe, reliable and highly reliable, and its device is simple in combination, convenient in manufacture and reliable in operation.

Description

technical field [0001] The invention relates to a silicone oil transformer oil injection process, especially to fully inject silicone oil into the transformer and ensure the vacuum degree in the transformer, so that the air content is very small and the silicone oil can completely penetrate into the insulating parts; the invention also relates to the realization of the silicone oil transformer oil injection Craft device. Background technique [0002] At present, most of the vehicle transformers use simple normal pressure oil injection method. Due to the compact internal structure of the transformer, the vacuum degree in the transformer and the complete infiltration of transformer oil into various parts of the transformer cannot be guaranteed, resulting in many problems in the operation of the transformer. To a certain extent, it affects the high performance and life of the silicone oil transformer. Contents of the invention [0003] The technical problem to be solved by t...
