Problems solved by technology
[0002] In order to ensure the high requirements of power customers for power quality, the on-load tap-changer needs to adjust the gear frequently to realize the correct running tap position of the transformer. During the frequent adjustment of the on-load tap-changer, the arc of the on-load tap-changer is extinguished Volatile gases such as hydrogen and acetylene will be produced in the room insulating oil. When the produced gas exceeds a certain volume, it will cause the non-electrical protection device of the transformer to operate, causing the transformer to stop running unplanned, and endangering the safety of power production in serious cases.

The invention belongs to the technical field of power transmission and transformation equipment maintenance, and particularly relates to a transformer on-load switch degassing device convenient for field operation. The device comprises an on-load tap-changer, an oil pumping pipeline and an oil injection pipeline are connected to the on-load tap-changer, one end of the oil pumping pipeline extendsto the bottom in the on-load tap-changer, and the other end of the oil pumping pipeline extends to the exterior of the on-load tap-changer and is connected with an oil pumping degassing device; one end of the oil injection pipeline extends to the upper portion in the on-load tap-changer, and the other end of the oil injection pipeline extends to the outside of the on-load tap-changer to be connected with the vacuumizing oil injection device. The degassing device has the advantages of being convenient to operate on site, good in degassing effect, simple in structure, convenient to install and operate and capable of saving degassing time, saving maintenance manpower investment, reducing maintenance capital investment and remarkably improving degassing quality. Volatile gases such as hydrogenand acetylene in the arc extinguish chamber insulating oil can be discharged to the atmosphere, and the index of the insulating oil in the arc extinguish chamber of the on-load tap-changer is ensuredto accord with operation regulations.
