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

Embodiment Construction

[0012] Referring to the accompanying drawings, the upper and lower valves of the transformer 1 are connected with a silicone oil treatment system 2 and a vacuum system 3 through a three-way pipe, the expander of the transformer 1 is connected with a pressurized static release system 4, and the PLC circuit control box 5 is connected with the pressurized static The discharge system 4 is electrically connected with the vacuum system 3.

[0013] Referring to the accompanying drawings, dry the body of transformer 1 at a temperature of 100-130°C for 38-58 hours, and connect the upper and lower valves of transformer 1 with the silicone oil treatment system 2 and the vacuum system 3 through a three-way pipe to keep the temperature of the silicone oil at 60°C. At ~70°C, through the upper valve of transformer 1, vacuum system 3 is used to pump the vacuum inside transformer 1 to below 100Pa, and oil is filled through silicone oil treatment system 2. After the silicone oil is filled, conti...

Abstract

The present invention discloses a silicon oil transformer oil injection process and a device thereof. Upper and lower valve of transformer (1) passes through three-way pipe and connects with silicon oil processing system (2) and vacuum system (3), a expander of transformer (1) connects with pressurized static release system (4), PLC circuit control box (5) electrically connects with pressurized static release system (4) and vacuum system (3). All coefficient of silicon oil injected into the transformer can be guaranteed when silicon oil is injected, all trouble probability of the transformer can be reduced, and all expenses brought by transformer reworking can be reduced. The invention describes a silicon oil injection method with operation simple, convenient, secure and reliable. The combination of the device is easy, production convenient and running reliable.

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...
