Embodiment Construction

[0016] The invention belongs to a visual detection method for a mobile on-site partial discharge source of GIS equipment, and the detection steps are as follows:

[0017] First, ultrasonic and ultra-high frequency detection methods are used to detect the partial discharge source of GIS equipment, and then the X-ray digital imaging detection method is used to visually locate the partial discharge source inside the GIS equipment, so as to realize the partial discharge detection of internal faults or defects in power GIS equipment. Reliable diagnosis of electrical discharges;

[0018] Identify a partial discharge source within the GIS equipment using ultrasonic testing;

[0019] Use ultra-high frequency detection method to determine a partial discharge source in GIS equipment;

[0020] Using X-ray digital imaging detection method, focusing on the area of ​​partial discharge source found by ultrasonic or ultra-high frequency detection method, can realize the visual displa...

Abstract

The invention discloses a mobile field partial discharge source visual detection method for a GIS (gas insulated switchgear), which comprises the following steps of: firstly performing the partial discharge source detection on a GIS by using an ultrasonic and ultra-high frequency detection method, then performing the visual location on a partial discharge source in the GIS by using an X-ray digital imaging detection method; meanwhile, determining a partial discharge source in the GIS by using the ultrasonic and ultra-high frequency detection method; and then using the X-ray digital imaging detection method to visually show the specific position of the partial discharge source in the GIS in a region where the partial discharge source is discovered by using the ultrasonic and ultra-high frequency detection method. The partial discharge source in the GIS can be rapidly and visually located without detaching the device and cutting off power; therefore the mobile field partial discharge source visual detection method can be movably used in the same field and different fields, has the outstanding advantages of mobility, high efficiency and reliability, and can visualize the fault or defect partial discharge position.

Description

technical field [0001] The invention relates to a method for visual detection of partial discharge sources of electric power equipment, and is especially suitable for the technical field of visual detection of partial discharge sources of mobile GIS equipment without dismantling the equipment and without power failure. Background technique [0002] GIS (Gas Insulated Combined Electrical Appliance) equipment includes circuit breakers, busbars, disconnectors, current and voltage transformers, earthing switches, lightning arresters, bushings and transition elements, etc., and all of them are assembled in a closed metal shell, filled with SF 6 Gas to achieve reliable insulation between conductors, phases, shells, fractures and fractures. GIS is used more and more widely in the power grid due to its advantages of small footprint, convenient installation and high reliability. GIS has high reliability, but it is a fully enclosed composite structure equipment. Once a failure occur...
