Abstract

The invention relates to a cable insulation layer thickness monitoring method and device, and in particular relates to a real-time cable insulation layer thickness monitoring method and device. The real-time monitoring device comprises a fiber grating sensor, a light source, an optical fiber demodulator and a monitoring and warning system. The fiber grating sensor is tightly coupled with a cable insulation layer. The fiber grating sensor is connected with the light source and the optical fiber demodulator. The optical fiber demodulator is connected with the monitoring and warning system. According to the invention, the problem of real-time cable insulation layer thickness variation monitoring is solved; the accident of insulation failure caused by the thinning of the insulation layer is avoided; and the safety of a high voltage and high current carrying cable, such as an electric spark focus discharge cable, is greatly improved.

Description

technical field [0001] The invention relates to a method and a device for monitoring the thickness of a cable insulation layer, in particular to a method and a device for real-time monitoring of the thickness of a cable insulation layer. Background technique [0002] The EDM seismic source is a seismic source that vaporizes the water body to form elastic waves by using an arc generated by high-voltage pulse discharge. It is used in various seismic survey fields such as oil exploration, mineral exploration, and engineering survey. When the spark source discharges, it is generally necessary to transmit the electric energy in the capacitor to the discharge head through the discharge cable. Since the discharge time of the spark source is very short and the energy storage energy is very large, the requirements for the discharge cable are very high, mainly reflected in the insulation capacity and current carrying capacity. For example, for an electric spark source with a nominal ...
