Abstract

The invention discloses a detection method, device and equipment of a high-voltage line. Wherein, the method includes: acquiring the magnetic field strength of multiple coils; determining the position of the high-voltage line based on the magnetic field strength of the multiple coils; and displaying the position of the high-voltage line. The invention solves the technical problem that the prior art can only give an alarm when the detector is close to the high-voltage line, and the detection accuracy is low.

Description

technical field [0001] The invention relates to the field of electrical equipment maintenance, in particular to a detection method, device and equipment for high-voltage lines. Background technique [0002] During the maintenance of underground electrical equipment, workers need to detect the electrification of the high-voltage lines in the environment and check the possible leakage areas. Once there is negligence and a high-voltage source is missed, it will endanger the lives of workers. Safety. Therefore, the monitoring of the environment must be very careful. [0003] The existing technology can only use contact or non-contact tools to detect specific points or areas, which requires workers to have a detailed understanding of high-voltage lines and possible leakage areas in the environment, and to conduct careful and comprehensive inspections. Non-contact AC voltage detection technology is an existing mature technology for detecting nearby high-voltage electrical signal...
