Background
Gis (gas Insulated substation) is the english name of a gas Insulated substation. In gas-insulated substations, most of the electrical equipment is directly or indirectly sealed in a pipe tree consisting of metal pipes and bushings, and no switches, lines or terminals are visible from the outside. The interior of the pipe tree totally adopts SF6 gas as an insulating medium, and all high-voltage electrical components are sealed in a grounding metal cylinder. The high-voltage distribution device is formed by combining high-voltage devices such as a circuit breaker, a bus, an isolating switch, a voltage transformer, a current transformer, a lightning arrester, a sleeve and the like.
In GIS substations at home and abroad, a large number of on-line monitoring means such as partial discharge probes, arc light probes, video probes and the like are used for monitoring the insulation performance of the GIS and judging fault positions in the GIS, but under the influence of various probe principles and different functions, the probe with one principle is often adopted, so that the insulation performance of the GIS and the fault positions in the GIS cannot be eliminated and the interference cannot be eliminated and the fault positions in the GIS can be accurately judged. Therefore, under the condition that SF6 gas in the GIS is not recovered, probes with different principles are replaced, and the test results are compared to judge the insulation performance of the GIS and the fault position in the GIS, which is more and more important. The existing probes applied in the GIS are internally arranged and externally arranged; the built-in probe is arranged in the shell and is slightly interfered by the outside; but the arc and video probe must be built-in. At present, other GIS manufacturers basically adopt a probe with the same principle as the online monitoring of GIS insulation performance, the probe and a bracket are arranged in a GIS shell, only one probe can be arranged on one bracket, SF6 gas needs to be recycled firstly when the built-in probe is replaced, and then the probes with different principles and the brackets matched with the probes are replaced.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: how to change probes of different principles without recovering the SF6 gas in the GIS.
In order to solve the technical problem, the technical scheme of the utility model is to provide an embedded online monitoring probe bracket, which is characterized by comprising a transparent window body, wherein a probe groove capable of placing built-in probes with different principles is arranged in the transparent window body, a detachable pressing plate is arranged at the opening of the probe groove, one side of the pressing plate is fixedly connected with the transparent window body, and a pressing plate wire hole is arranged at the opening of the probe groove on the pressing plate; an internal thread connecting sleeve which is fixedly connected with the built-in probe is arranged in the probe groove.
Preferably, a protective cover is arranged on the other side of the pressing plate; one side of the protective cover connected with the pressure plate is of an open structure; one side of the protective cover closest to the ground is provided with a protective cover wire hole.
Preferably, sealing rings are arranged on one side of the transparent window body connected with the pressure plate and one side of the transparent window body connected with the GIS shell; the sealing ring is sleeved outside the edge of the probe groove.
Preferably, the side of the transparent window body connected with the pressure plate and the side of the transparent window body connected with the GIS shell are both provided with a sealing groove, and the sealing ring is arranged in the sealing groove.
Preferably, a plurality of mounting holes and threaded holes are uniformly distributed around the transparent window body; a plurality of through holes are arranged on the pressing plate; the protective cover penetrates through a through hole in the pressure plate through a bolt to be fixed in a threaded hole of the transparent window body, the transparent window body penetrates through a mounting hole through a bolt to be fixed on the GIS shell, and the pressure plate is fixed in the threaded hole of the transparent window body through a bolt.
The utility model provides an embedded on-line monitoring probe support, the internal thread adapter sleeve in the transparent window can with the office put probe, arc light probe, video probe fixed connection effectively to carry out the fixed of wire through the clamp plate. Through using the utility model discloses a support, under the gaseous condition of SF6 in not retrieving GIS, can be according to different monitoring facilities's demand, change the built-in probe of different principles selectively (probe, arc light probe, video probe are put in the office) to install in the transparent window body, the probe can simply, get rid of the interference effectively through transparent window body, monitors GIS's insulating properties, confirms the fault location in GIS.
