Problems solved by technology

[0006] The vacuum oil filter 10 needs to be shut down every 2 hours to clean the insulating oil in the condenser 12 and the separator 14, and to filter the insulating oil required for a UHV reactor, it needs to be shut down repeatedly for cleaning more than 20 times. Low efficiency, does not meet the working requirements of on-site continuous oil filtration

Abstract

The invention relates to a vacuum oil filter. A coarse filter, a gear pump, a heater, a fine filter and a degassing chamber are sequentially connected between a filling valve and a delivery valve of the vacuum oil filter, wherein the degassing chamber is communicated with a separator, a lobe pump, a condenser, and a vacuum pump in turn; a first oil drainer and a second oil drainer are respectively rearranged below the separator and the condenser; a first oil drain valve is arranged between the first oil drainer and the separator and is provided with a third oil drain valve; a second oil drain valve is arranged between the second oil drainer and the condenser; and the second oil drainer is provided with a fourth oil drain valve. With the first oil drainer and the second oil drainer, the vacuum oil filter realizes the continuous operation, simultaneously prevents humidity in the air from entering the vacuum oil filter, and ensures the quality of filtered oil.

Description

technical field [0001] The invention relates to the field of high-voltage substations, in particular to a vacuum oil filter. Background technique [0002] UHV transformers and UHV reactors used in UHV substations and other large oil-invaded equipment need to use a large amount of insulating oil due to the high heat generated during the operation of the equipment. Taking the UHV Nanyang Substation as an example, the insulating oil volume of a single UHV reactor reaches 100 tons, and the insulating oil volume of 7 UHV reactors reaches 700 tons, so the workload of oil handling during the installation process is quite large . Taking the filtration of a 25-ton tank of insulating oil as an example, the vacuum oil filter needs 10 hours to filter the insulating oil under continuous operation, and 40 hours of continuous oil filtration can ensure the oil consumption of an UHV reactor. During the reactor installation, the working performance of the vacuum oil filter, especially the c...
