摘要
变压器是电力系统中关键的设备之一,承担着电压变换,电能分配和传输,为众多用户服务。因此,变压器的正常运行是电力系统安全、可靠、优质、经济运行的重要保证,必须最大限度地防止变压器出现故障。但由于变压器长期运行,故障和事故不可能完全避免,而且引发故障和事故的原因也是多种多样的。绝缘老化、违章作业、外力破坏,都会造成事故或导致事故扩大,从而危及电力系统的安全运行。
The transformer is one of the most important equipment in the electric power system. It is responsible for voltage transform, power distribution and power transmission for many users. Therefore, the normal operation of the transformer guarantees the secure, reliable and economic operation of the power system. Consequently, the transformer must be maximally prevented from the failure. However, due to the long-term operation of the transformer, the failure and accident cannot be completely avoided. In addition, there are many reasons for the failure and accident. For example, insulation aging, improper operation, and external destruction can result in an accident or exoand the accident, thu~ endnno-grlntr th. ~of~ ;~ ^C .L_ _1
