Abstract

The invention relates to a constant-temperature protection box of an electrical device detection instrument. The box comprises a box body, wherein a combined socket, a direct current power supply and a comprehensive measuring and control device are arranged on the box body, the combined socket is connected to the direct current power supply, the direct current power supply is connected to the comprehensive measuring and control device, one side of the comprehensive measuring and control device is connected to a sensor and a heating device, and the other side of the comprehensive measuring and control device is provided with L, N and PE wiring terminals. By the aid of the box, the problem that the electrical device detection instrument cannot work normally at the lower temperature is solved, the electrical device detection operation can be completed timely and the electronic system works safely and reliably.

Description

technical field [0001] The present invention relates to a movable and portable industrial equipment box, in particular to a constant temperature protection box for power equipment testing equipment, which is suitable for on-site heat preservation or protection of power testing equipment, and can be adapted to power equipment of various power testing equipment in harsh low-temperature environments Debug on-site use. Background technique [0002] Many power supply companies are located in alpine regions and have a large number of substations. In order to ensure the reliability of power supply, 80% of new installations, business expansion and overhaul projects are scheduled during winter. The newly installed electrical equipment must carry out relevant handover tests, which brings many difficulties to the high-voltage test work. The outdoor temperature during the winter test work is below minus 10 degrees. With the rapid development of science and technology today, the test eq...
