减少颗粒度对变压器油电气性能影响

变压器油中颗粒污染影响绝缘油的电气性能,尤其是金属颗粒的含量,因此如何控制颗粒度指标,才能保证变压器等充油电力设备的安全运行。
Particle pollution in transformer oil affects the electrical performance of insulating oil, especially the content of metal particles. Therefore, how to control the particle index can ensure the safe operation of oil-filled power equipment such as transformers.
变压器油为您分析减少颗粒度影响的措施:
Transformer oil will help you analyze the effect of reducing particle size.
(1)变压器器身、铁心、油箱内壁等所用材料、胶、漆等与变压器油之间有可靠的相容性,长期运行后不会脱落、分解并影响油质。
(1) There is reliable compatibility between transformer oil and materials such as transformer body, core, inner wall of oil tank, glue and paint, which will not fall off, decompose and affect oil quality after long-term operation.
(2)变压器绝缘件制造、线圈绕制、器身装配等重要生产车间必须保证场地清洁。对于高压产品而言,应做到车间全封闭,最好能有保持正压的条件,减少浮尘对器身的污染。

(2) Important production workshops, such as transformer insulation manufacturing, winding and body assembly, must ensure that the site is clean. For high-pressure products, the workshop should be completely closed, the best conditions to maintain positive pressure, reduce dust pollution to the body.
(3)对油箱、联管等部件,应在装配前做好内部清洁工作,在拆卸搬运时更应做好封闭保护工作,防止其内表面的污染。安装前须对设备相关部件、管道等进行认真的油循环冲洗。
(3) Internal cleaning should be done well before assembly of oil tank and joint pipe, and sealing protection should be done well during disassembly and handling to prevent contamination of inner surface. Before installation, the equipment related parts and piping must be seriously washed by oil circulation.
(4)对于现场吊芯等检修工作,应在天气晴好无风的时候进行,器身暴露时间也应当严格控制,以防止受潮、避免污染。
(4) For on-site core maintenance, it should be carried out when the weather is fine and windless, and the exposure time of the body should be strictly controlled to prevent dampness and pollution.
(5)新变压器油注入设备前,必须采用真空滤油机真空注油工艺,经过滤油装置的净化处理后,油中杂质将能有效减少。
(5) Before the new transformer oil injection equipment, it is necessary to adopt the vacuum oil injection technology of the vacuum oil filter. After the purification treatment of the oil filter, the impurities in the oil will be effectively reduced.
