Problems solved by technology
This kind of dangerous area fence can not show whether the pressurization test is in progress, there is no indication and alarm function of the working status, and there is no control device related to the high-voltage power supply of the withstand voltage test. When one equipment test is completed and the next equipment is tested, It cannot clearly show whether the pressure is being applied for a certain period of time during the process, and the test personnel may stray into the high-voltage electric field, which is prone to dangerous accidents

The invention discloses an infrared fence of a high voltage room. The infrared fence is provided with stand columns, wherein the lower end of each stand column is provided with a pedestal, and the upper end of each stand column is provided with an audible and visible alarm; each stand column is provided with infrared transmitting tubes and infrared receiving tubes which are axially and uniformly distributed along the stand column; the direction of the infrared transmitting tubes is perpendicular to that of the infrared receiving tubes; a controller is arranged in each stand column; a circuit board is arranged in the controller; and the control board is provided with a control circuit which can be used for transmitting a light alarm signal after a high-voltage power signal is connected, transmitting a sound alarm signal after an infrared barrier signal is received and cutting off the light alarm signal after the high-voltage power signal is cut off. The infrared fence of the high voltage room is provided with the infrared fence, the alarm and the controller; the occurrence of a barrier phenomenon of entering a dangerous region can be associated with on and off of a high-voltage power supply of an alarm and test table; and dangerous accidents do not easily happen during high-voltage test on equipment.
Description
technical field [0001] The invention relates to an auxiliary device used in high-voltage electric test, in particular to an isolation device used in high-voltage electric test. Background technique [0002] When carrying out the withstand voltage test on the electric equipment in the high-voltage room, a high-voltage power supply should be used to apply high-voltage electricity to the electric equipment under test, and the high-voltage electricity can reach tens of kilovolts to hundreds of kilovolts at most. During the withstand voltage test, there is a high-voltage electric field around the power equipment with high-voltage electricity. The high-voltage electric field is a dangerous area. The tester will get an electric shock accident when entering the high-voltage electric field. During the withstand voltage test, in order to prevent the tester from entering the above-mentioned dangerous area by mistake, Hazardous areas must be marked. In order to mark the dangerous area,...
