The human body sensor consists of an infrared imager and an ultrasonic sensor; the infrared imager is used for judging the approaching object as a human body; the ultrasonic sensor is used for judging the distance of the approaching human body. The thermal infrared imager is detection equipment which detects infrared heat in a non-contact manner, converts the infrared heat into a thermal image and a temperature value, displays the thermal image and the temperature value on a display and can calculate the temperature value. The thermal infrared imager can accurately quantify the detected heat and can accurately identify and strictly analyze the heating fault area. After the infrared thermal imager judges that the object is a human body, the ultrasonic sensor transmits ultrasonic waves, then the distance of the human body is judged according to the reflected ultrasonic waves, and after the distance of the human body enters a preset range, the voltage sensor and the current sensor are controlled to detect the voltage and the current of the shell. The preassembled transformer substation can be used for judging the human body and judging the distance, so that an alarm is sent to a person more pertinently, and the safety of the preassembled transformer substation is high.
