High-voltage test area alarming device

Abstract

The invention relates to a high-voltage test area alarming device which comprises a host as well as a plurality of first infrared detectors and a plurality of second infrared detectors which are connected with the host, wherein a power supply module, an alarming module and a control module are arranged inside the host; a rectifying unit is arranged in the power supply module; the alarming module comprises an alarm and an alarming control circuit; and the control module comprises a power supply output terminal and an output control circuit. According to the high-voltage test area alarming device, two protection modes, namely, audible and visual alarming and automatic cutoff of a testing power supply are introduced into high-voltage test alarming, so that the safety accidents of loss of life and personal injury, equipment damage and the like of the high-voltage testing area can be effectively prevented, and the safety and the reliability of high-voltage testing are improved.

Description

technical field [0001] The invention relates to a test auxiliary equipment in the technical field of electric power systems, in particular to an alarm device. Background technique [0002] The high voltage test is a test to test the insulation performance of power transformers and other electrical equipment, and it is one of the key test items to ensure the safe and effective operation of the power system. The high-voltage test area includes the high-voltage test area, the alarm area and the safety area, such as figure 1 As shown, the high-voltage test area is the high-voltage test equipment and the area that must meet the safety distance requirements of the high-voltage test. Generally, it refers to the area about 5m away from the high-voltage test equipment. No one is allowed to approach. The alarm area is a more dangerous area near the high-voltage test area than the safe area. Generally, it is an area with a distance of 2m around the high-voltage test area. When the hi...

However, such products only send out an alarm signal when people enter the alarm area, and personal electric shocks may occur because people are too late to evacuate

Moreover, during the use of such products, the sound and light alarm signal only serves as a warning, the test equipment is still in working condition, the danger of high voltage still exists, and safety accidents such as electric shock casualties and equipment damage may still occur

In addition, when the alarm fails or is destroyed, such products cannot play a warning role, which increases the possibility of safety accidents such as casualties and equipment damage.
