A method for high-voltage live display using a high-voltage live display device

Abstract

The invention discloses a high voltage presence indicating device and an implementing method thereof, and mainly solves the problems that high voltage presence indicating devices are mostly powered by batteries or external power supplies, the batteries are inconvenient to replace and are easily influenced by the heat of high-voltage electrical equipment to cause device failure, and the security is low in the prior art. The high voltage presence indicating device comprises a detection transmitting end and a receiving display end, wherein the detection transmitting end and the receiving display end are completely isolated on the high voltage side and the low voltage side, and communicate with each other through wireless radio frequency; the detection transmitting end comprises an electric field coupling-based inductive energy fetching device for providing working electric energy for the detection transmitting end. By the scheme, the aims of safety, reliability and wide application range are fulfilled, and the high voltage presence indicating device has high practical value and promotional value.

Description

technical field [0001] The invention relates to a security device, in particular to a method for performing high-voltage live display using a high-voltage live display device. Background technique [0002] In recent years, high-voltage live display devices have been widely used in power systems to prevent electrical misoperations. Most of the traditional high-voltage live display devices use wired detection methods, which require power-off installation and changes to the original lines. There are various safety hazards in the operation process, and have been gradually replaced by new devices. [0003] Most of the current new devices use wireless communication methods, and cooperate with the use of various electronic components such as single-chip microcomputers to realize live detection of high-voltage electrical equipment. In such solutions, most of the detection sensors are powered by batteries or external power sources. However, batteries It is extremely inconvenient to ...
