Technical field
Integration test device of the present invention belongs to the DC experiment technical field that electric power is used analog detection GIS kind equipment state of insulation.
Background technology
Metallic conducting particle is the chief threat of GIS safe operation in GIS built-in electrical insulation defective, it is detected significant.
Metallic conducting particle is the most important typical defect of GIS inherent vice, it is detected the quality that effect directly determines detection method, the detection yet classic method insulate under alternating voltage usually, under higher alternating voltage, the situation that the direct flashover of not take-off of metal particle or gap usually occurs, the GIS insulating property are had larger damage, and effect is not good enough.Under this voltage environment in the GIS particle movement pattern mostly be and roll or non-penetrability is beated.The various signals that particulate sends a little less than, be unfavorable for detection of particles.
Particulate take-off voltage and the penetrability required voltage of beating is lower under the DC voltage, the GIS insulating property there is less damage, and the unipolar cause of DC voltage, metal particle is easier to move freely and passes through whole gap in the GIS gap, multiform becomes the penetrability pattern of beating, the signal intensity that free particulate discharges is far longer than stationary state, and the ultrasonic and pulsed current signal that sends is stronger, thereby the method is more effective.
In the local discharge test of Simulated GlS typical defect, because the metal particle that adopts is small, voltage often occurs and particulate is hit situation about flying.In this test unit at SF
6Be provided with the particulate collecting groove in the test closed cavity, collection of particles is collected, avoid microparticle residue in cavity.
The DC power system that adopts in the test at the scene is light than AC power supply system, and operability is stronger, provides exercisable method for testing and detecting for GIS examines prerun surely, in time finds the apparatus insulated defective of GIS, guarantees that the GIS transmission of electricity is safe and reliable.
