Abstract

The invention belongs to the technical field of high-voltage switchgear equipment, and relates to a passive high-voltage switchgear live sound and light alarm device. The sound and light alarm deviceis arranged in a high-voltage switch cabinet and includes a high-voltage energy-taking detection module, an alarm processor, a light-sensing module, an indicating lamp and a buzzer. The high-voltage energy-taking detection module is connected to a live device in the high-voltage switch cabinet, and is connected to the alarm processor, and the light-sensing module is connected to the alarm processor which is connected to the indicating lamp and the buzzer and is used for controlling the indicating lamp and the buzzer to emit sound and light alarm. The device is compact in structure and can monitor the live condition of internal equipment of a high-voltage switchgear in real time. When the cabinet door of the switchgear is opened, the sound and light alarm can be emitted, people are effectivley prevented from entering a live unit mistakenly, and personal accidents are avoided.

Description

technical field [0001] The invention relates to an acousto-optic alarm device, especially a passive acousto-optic alarm device for a high-voltage switchgear, which is mainly used in a special live alarm device for internal equipment of a metal-enclosed high-voltage switchgear, and belongs to the technical field of high-voltage switchgear equipment . Background technique [0002] As a combination of various power equipment and instruments, high-voltage switchgear has the advantages of small size, convenient operation, and reliable operation. It is the most widely used equipment in substations. At present, the high-voltage switchgear mainly adopts two methods of live display and ground knife mechanical interlocking to solve the problem of operators "entering the live interval by mistake". [0003] In actual operation, the failure rate of live monitors remains high, and floor knife operation failures also occur frequently. In this case, when the operator removes the fastening ...
