How to judge whether there is a fault in the electrical equipment in the switch cabinet by hand feeling temperature method

Touch temperature method is only suitable for touching some electrical equipment in low-voltage switchgear by hand after power failure. If there is electricity, some bare conductors cannot be used to judge the temperature of electrical equipment by touch temperature method. At this time, it is suggested to Taitai Electric that the temperature of electrical equipment can be judged by using a temperature indicating wax sheet or a temperature measuring patch. Necessary safety measures should be taken before touching the electrical equipment in the switch cabinet: ① cut off the power supply, such as unplugging the safety plug, unplugging the voltage plug and disconnecting the power switch; (2) Or put on electrical rubber shoes with good insulation, stand on a dry board or stool and touch with one hand. Other parts of the body are not allowed to touch walls, floors or electrical equipment.
