Problems solved by technology

During the high-voltage test, there are the following problems: at the working site of the high-voltage test, thousands of volts or even higher high voltage will be generated during the detection process, and the high-voltage test is performed on large-scale power transformers, GIS equipment, busbars, etc. When the pressurized area is very large, even though there are temporary protective fences in the pressurized area and there are test personnel monitoring, non-high pressure test personnel may still enter the pressurized area by mistake in the dead angle position where the test personnel cannot monitor
However, the existing safety fences and ropes can only serve as a warning during the high-pressure test, and cannot prevent personnel from entering and touching by mistake, thus failing to effectively protect the safety of personnel and equipment.

Abstract

The invention provides an infrared safety monitoring device and a device provided with the infrared safety monitoring device and used for safety protection during a high-voltage test. The device used for safety protection during the high-voltage test comprises an auxiliary power circuit. The auxiliary power circuit is used for converting electric power coming from a power grid into a constant-voltage low-voltage direct current and supplying the constant-voltage low-voltage direct current to the infrared safety monitoring device. The infrared safety monitoring device comprises an infrared signal generation unit, a signal monitoring unit, a detection signal processing unit, a logical control unit and a trip warning unit.

Description

technical field [0001] The invention relates to an infrared safety monitoring device and a device for safety protection during a high voltage test with the infrared safety monitoring device. Background technique [0002] In the power system, the high-voltage test is an important link in the operation and maintenance of power equipment, and it plays a very important role in ensuring the safe operation of the primary equipment of the power system. During the high-voltage test, there are the following problems: at the working site of the high-voltage test, thousands of volts or even higher high voltage will be generated during the detection process, and the high-voltage test is performed on large-scale power transformers, GIS equipment, busbars, etc. When the pressurized area is very large, even though there are temporary protective fences in the pressurized area and the test personnel monitor it, non-high pressure test personnel may still enter the pressurized area by mistake ...
