Problems solved by technology

However, there is currently no comprehensive device on the market that meets the actual work requirements of the site and meets the technical requirements of the equipment. The degassing device widely used by the staff is a vacuum degassing and oil changing device temporarily assembled on site, which has poor integrity. Vacuum pumps, oil and gas separators, The components such as hoses and electrical controls are completely separated, and the components are stored scattered; the specificity is not strong, and each device is multi-purpose at ordinary times, and the temporary combination, mismatch, and error-prone; it is inconvenient to move, and the scattered components need to be disassembled every time when the work site is transferred. Transportation and reassembly are costly and time-consuming; the operation is cumbersome and repetitive, each time the parts need to be temporarily assembled on site, and each time a sealing test is required, which is a waste of time and the airtightness is difficult to guarantee; safety is not reliable, and the vacuum equipment has no effect on the air. The requirements for airtightness are very high, the airtightness cannot be guaranteed, and the efficiency is low, making the equipment safe and unreliable
The above-mentioned deficiencies have occurred many times, causing the efficiency of the working equipment to decline, repairing or even emergency shutdown of unsafe incidents

Description

technical field [0001] The invention relates to an automatic degassing and oil changing device. Background technique [0002] At present, due to the increase of oil chromatographic abnormalities in high-voltage oil-immersed bushings and transformers of 110KV and above, it is often necessary to change oil and degas the equipment. This kind of work requires high technology, and the power outage time of equipment is getting higher and higher. , requires equipment with reliable process and short time. However, there is currently no comprehensive device on the market that meets the actual work requirements of the site and meets the technical requirements of the equipment. The degassing device widely used by the staff is a vacuum degassing and oil changing device temporarily assembled on site, which has poor integrity. Vacuum pumps, oil and gas separators, The components such as hoses and electrical controls are completely separated, and the components are stored scattered; the s...
