What are the common failures in the use of baoding oil immersed transformer? This is a problem that many users are very concerned about. Today, baoding oil transformer supplier jiangsu school of electrical co., ltd. briefly analyzed the common failure of baoding oil immersed transformer:
The fault of baoding oil immersed transformer is often divided into internal fault and external fault. The details are as follows:
A, internal fault for all kinds of fault occurs in the transformer oil tank, its main types are: each phase winding between phase short circuit, winding turn ask short circuit between turns, winding or lead wire through the shell of the earth fault, etc.
The internal fault of transformer is generally divided into two categories: thermal fault and electrical fault. Thermal failure is usually caused by local overheating and temperature rise. According to its severity, thermal faults are often classified as mild overheating (generally less than 150), low temperature (150-300), medium temperature overheating (300 ~ 700), and high temperature (generally higher than 700). Electrical failure usually refers to the failure of insulation performance degradation or deterioration due to the high electric field strength in the transformer. According to the energy density of the discharge, the fault is divided into three types: partial discharge, spark discharge and high energy arc discharge.
Second, the external fault of transformer tank external insulation casing and lead to various failures occur online, its main types are: electrical insulators flashover or broken and grounding < short circuit through a shell), such as phase asked fault occurring between lead and cause transformer internal fault or winding deformation, etc.
In addition, due to the wide range of transformer faults, specific types are divided into many types, such as circuit faults, magnetic circuit faults and oil circuit faults. If the main structure of transformer is divided, it can be divided into winding fault, core fault, oil fault and accessory fault. At the same time, the type of transformer fault is usually classified according to common fault prone location, such as insulation fault, core fault, split-switch fault, etc. And impact on the transformer itself, the occurrence probability of the highest and the most serious fault transformer exports, at the same time there are transformer leakage failure, the failure of oil flow electrification, protection misoperation, and so on. All of these different types of faults, and some may reflect the hot fault, some may reflect the electrical failure, some may reflect both overheating fault exists discharge breakdown again at the same time, the transformer leakage fault in the general case the characteristics of thermal or electrical failure may not exist.
Above is the summary of baoding baoding oil-immersed transformer supplier analysis common fault types of oil-immersed transformer through the above content, the user can accurately judge the transformer fault features in use, the processing of targeted feedback, ensure use safety.
