The Research on One Feasible Test Strategy for Temperature Rising Limits of Low-Voltage Metering Cabinets

摘要

The consumption of electric power is increasing with the continuous development of China's economy. The temperature rising limits testing is the important performance for low-voltage metering cabinets and circuit breakers. The strategy for temperature rising testing usually had many questions such as the style of thermocouple pasting, long testing time, the randomness by operator and so on. According to amount experiences for low-voltage metering cabinet, a good strategy for temperature rising limit testing was proposed in the paper. Meanwhile, the grey model used to analysis the temperature rising data for the growth trend of data itself.
