The utility model provides a high-voltage test site state monitoring system. The high-voltage test site state monitoring system comprises a control system, a temperature sensor, a humidity sensor, a safety blocking device, a voice broadcasting device and a light warning device, the temperature sensor and the humidity sensor are both arranged in a test site; the safety barrier device comprises fourgroups of opposite-type infrared sensors, transmitting ends and receiving ends of each group of opposite-type infrared sensors are correspondingly arranged, and opposite-type paths between the transmitting ends and the receiving ends of the four groups of opposite-type infrared sensors form a rectangular safety barrier range; the voice broadcast device and the light warning device are electrically connected with the microprocessor through a voice broadcast circuit and a light warning circuit respectively. According to the utility model, the environment temperature in a high-voltage test siteand the intrusion situation of personnel in the test process can be monitored in real time, automatic action and voice warning can be realized, a test power supply can be cut off autonomously when necessary, and the test data error rate of a high-voltage test and the risk of personal injury to personnel are reduced remarkably.
