Sichuan Yibin Electric Power Bureau has installed a new 220KV transformer in Longmen Power Station. This transformer is produced by Xinjiang TBEA, and its oil load is more than 38t. After installation, check whether the oil contains acetylene; Several oil filters of Yibin Electric Power Bureau were immediately used for on-site treatment. After more than half a month of oil filtering, the transformer oil still contains acetylene.

The company rented a ZYA-200 double stage vacuum oil filter. It was transported to Longtou Power Station, and the acetylene problem was completely solved after 3 days of treatment. Oil sampling test: acetylene is 0, ethane is 0, ethylene is 0, hydrogen is 0, and total hydrocarbon is only 0.2; The micro water content is 2mg/L—— This is tested by Sichuan Electric Power Test and Research Institute.

Jiangsu Nantong Youbang Transformer Co., Ltd

Order ZYA-100 two-stage vacuum oil filter, and send the oil sample to Nanjing Electric Power Test and Research Institute. The test results show that the water content is 2 ppm, breakdown voltage is 73KV, acetylene=0, hydrogen=0, and gas content is 0.005%.

This machine is used to treat a transformer for high voltage test. The oil contains 46 ppm acetylene, which is zero after treatment.

Yunnan Tonghai Transformer Factory

Ordering ZYA-150 double stage vacuum oil filter, after processing the transformer oil, the acetylene gas contained is zero.

Jiangsu Suzhou Antai Transformer Co., Ltd

ZYA-100 two-stage vacuum oil filter ordered last year is mainly used to remove acetylene gas from transformer. The actual use effect is remarkable, and all the transformers treated by the machine meet the acceptance standards.

Shenyang Huamei Transformer Manufacturing Co., Ltd

In 2009, four ZYA-500 oil filters were purchased from our institute. The on-site oil filtering, vacuum oil injection and hot oil circulation drying of damped transformers ensured the effect of acetylene=0.

Jiangsu Gaoke Petrochemical Co., Ltd

The ZYA-500 oil filter will be purchased in 10 years to realize oil filtering at 32 º C low temperature. Once the oil is filtered (60t transformer oil is filtered in 3 hours), the qualified standard will be reached to ensure acetylene=0 and water ≤ 8PPM.

Many customers, such as Sanbian Science and Technology Co., Ltd., Xiangtan Huaxia Special Transformer Plant, Henan No.1 Thermal Power Company, Chengdu Xinxu Company, Chongqing Electric Power Bureau Repair and Test Institute, use our oil filter to ensure zero acetylene.

Henan Mianchi Aluminum Co., Ltd

The installed oil volume of 5 # main transformer and 4 # main transformer: the acetylene and hydrogen of 63T large transformer oil seriously exceed the standard and need to be treated urgently.

There are four vacuum oil filters in the plant, but none of them can completely remove acetylene, hydrogen and total hydrocarbon from transformer oil.

The factory borrowed an oil filter produced by me, and the effect is good after use. Therefore, we bought Model 200 double stage vacuum oil filter. We sent technicians to assist the plant to deal with the insulating oil of two large transformers day and night, completely solving the problems of acetylene, hydrogen and total hydrocarbon in the oil.

The main indicators of oil quality test before and after treatment of 5 # main transformer are compared as follows (content unit: μ L/L）：

Before and after treatment

Acetylene C2H2: 0.17 0

Hydrogen H2: 5345.9 7.59

Total hydrocarbon: 400.38 2.78

Tianjin Dagang Oilfield

Order 500 type double stage vacuum oil filter, which has large flow and good purification index. 152t transformer oil is processed in 8 hours, with an average of 19t per hour. After treatment, the voltage strength reaches 78KV, and the micro water removal limit reaches 1.12ppm.
