Research on Temperature Rise Inspection Technology of Low-voltage Cable Junction Box Used in Mine

Combined with the operating environment and fault factors, temperature rise inspection technology of mine low-voltage cable junction box was proposed. Based on the analysis of the existing temperature rise test temperature testing technology and thermocouple temperature measurement principle, we designed the overall structure for mine low voltage cable junction box temperature test system. Moreover, the temperature rise test demand of current deviation and power frequency were put forward, and the current transformer and temperature data recorder for system test were introduced. Meanwhile, the system for mining low voltage cable junction box test was set up test.
