fast multipurpose gis partial discharge measurement sensor fixture

Abstract

The invention relates to a multifunctional fast GIS partial discharge measuring sensor fixing device. The multifunctional fast GIS partial discharge measuring sensor fixing device comprises an outer frame, an upper pressing plate, side fastening plates, pull strips and a supporting rod. The outer frame is open and comprises a lower bottom plate, a left side plate, a right side plate, a front side plate and a back side plate. The upper pressing plate is connected to the interior of the outer frame in a sliding mode and is parallel to the back side plate, the side fastening plates are arranged on the left side and the right side in the outer frame and elastically connected with the left side plate or the right side plate through springs, one end of each pull strip is fixedly connected to the side fastening plates, the other end of each pull strip is a free end and stretches out of the outer frame, and the supporting rod and the lower bottom plate are hinged. A sensor fastening component for containing a fixing sensor is defined by the lower bottom plate, the upper pressing plate, the side fastening plates and the front side plate. Compared with the prior art, the multifunctional fast GIS partial discharge measuring sensor fixing device has the advantages of being safe and convenient to use, fast to mount and dismount, efficient and the like.

Description

technical field [0001] The invention relates to a GIS partial discharge measurement auxiliary device, in particular to a fast multipurpose GIS partial discharge measurement sensor fixing device. Background technique [0002] Gas-insulated metal-enclosed switchgear (GIS for short) has a history of more than 40 years since it appeared in the mid-1960s. It optimizes and designs all the primary equipment in a substation except the transformer into an organically combined whole. Compared with traditional open-type equipment, GIS has the advantages of high dielectric strength, low audible noise, no fire hazard, long maintenance cycle, saving floor space and less maintenance. It is gradually becoming the representative of modern substation equipment and is low-cost. A symbol of maintenance, even maintenance-free, high reliability, high safety. In recent years, GIS has been widely used in hub substations and urban center substations. This is not only the affirmation of its advanta...

AI Technical Summary

Problems solved by technology

In view of the fact that the built-in sensors are not installed in the GIS equipment of many old stations, and the on-site GIS equipment adopts a compact arrangement, it is difficult for many measurement position detection personnel to touch manually, and there are detection blind spots

Many substation GIS pipeline busbars are arranged on the upper and lower floors, and the location is relatively high. There is no professional climbing equipment on site, and the danger of personnel climbing is high. Many high-level measuring points cannot complete the inspection.

During the on-site inspection, it was found that there was a potential difference of 20V to 40V between the metal casing of the GIS equipment and the metal casing of the sensor that was grounded through the grounding point of the maintenance power supply, posing hidden dangers to the safety of inspection personnel

The potential safety hazards of on-site personnel need to be resolved urgently
