Abstract

The invention discloses a detection system of an oil-consuming device, belongs to the technical field of electrical detection equipment, and solves the technical problem of low efficiency of an oil paper aging detection mode in the prior art. The detection system comprises: a light source device capable of emitting at least two laser beams; a light source modulation assembly which can modulate a light source and / or change the energy level of the light source; a beam expanding and collimating device which is used for aggregating or combining different light sources; a detection assembly which can store air in an oil bin in the oil consuming device and can enable the light source aggregated by the beam expanding and collimating device to penetrate through the stored air, wherein the energy level and modulation of laser emitted by the light source device are changed through the light source modulation assembly, the laser is aggregated through the beam expanding and collimating device, andthe aggregated laser enters the detection assembly to complete the detection of the insulating oil paper. The detection system is used for perfecting the use function of an oil device, and meets therequirement of people for high insulation oil paper detection efficiency.

Description

technical field [0001] The invention belongs to the technical field of electrical detection equipment, in particular to a detection system of an oil-using device. Background technique [0002] As the key equipment in the power transmission and transformation system, the power transformer's safe and reliable operation is the first line of defense to avoid major accidents in the power system. Accurately diagnosing the early faults of oil-immersed power transformers, grasping the aging status of its oil-paper insulation in time, and preventing problems before they happen are one of the keys to ensure safe production of power grids and realize efficient maintenance of equipment. During the failure and aging process, the insulating oil and insulating paper of the oil-immersed power transformer will decompose and produce various gases that reflect the nature of the fault and insulation performance, and dissolve in the insulating oil. For example, the fault gas includes combustible...
