Description
Technical field
The invention belongs to the gas-insulating and fully-enclosed combined electrical apparatus technical fields of SF6, especially a kind of vacuum adsorption type office put
Probe apparatus.
Background technology
At present, with the fast development of power industry, the gas-insulating and fully-enclosed combined electrical apparatuses of SF6 (GIS) relies on its structure
Compact, floor space is little, good insulation preformance the advantages of, more and more applied in electrical network.However, GIS runnings
In, its failure constantly occurs, and drastically influence the development of electrical network.
Partial discharge detection is a kind of current means of the internal discharge defect of effective detection GIS at the scene, in order to prevent artificial cloth
The brought error of probe is put, current office puts probe and is fixed on equipment frequently by modes such as binding or magnet adsorptions.So
And because most of GIS enclosure materials are aluminium alloy, magnet adsorption means Jing often fail, and due to compact arrangement of equipment or
The problems such as arrangement position is too high, bundling the difficulty of probe also becomes increasing, so as to limit partial discharge detection in combined electrical apparatus
In application.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of reasonable in design, easy installation and reliable true
Probe apparatus are put in empty absorption type office.
The present invention solves its technical problem and takes technical scheme below to realize：
Probe apparatus are put in a kind of vacuum adsorption type office, by housing, spring, probe signal line, gas circuit line, vavuum pump and spy
Head is constituted, the housing bottom opening, and the upper end of the spring is arranged on the inside top of housing, lower end and the spy of the spring
Head is installed together and positioned at enclosure interior, in case top holding wire installing hole and gas circuit installing hole, the probe letter is provided with
Number line one end is connected with probe, and the probe signal line other end leads to hull outside, the gas by holding wire installing hole
Road installing hole is provided with gas circuit line, and the gas circuit line one end is inserted into inside cylindrical shell, and the gas circuit line other end connects
Vavuum pump is connect, in holding wire installing hole and gas circuit installing hole sealing ring is mounted on.
The housing is cylindrical shell.
Advantages of the present invention and good effect are：
The present invention is reasonable in design, and it is installed in enclosure interior and true by vavuum pump extraction housing by spring by probe
Sky, so as to probe tightly be adsorbed on GIS device surface, it is to avoid the mushing error that traditional detection mode is artificially introduced,
Improve the accuracy and convenience of detection.

Specific embodiment
The embodiment of the present invention is further described below in conjunction with accompanying drawing：
Probe apparatus are put in a kind of vacuum adsorption type office, as shown in Figures 1 and 2, by housing 1, spring 2, probe signal line 3,
Gas circuit line 4, vavuum pump 5 and probe 6 are constituted.The housing is the cylindrical shell of bottom opening, and the upper end of the spring is pacified
The inside top of cylindrical shell is mounted in, lower end and the probe of the spring are installed together and inside cylindrical shell,
The probe is popped one's head in for ultrasonic probe or for superfrequency.Holding wire installing hole 7 and gas circuit are formed with the top of cylindrical shell
Installing hole 8, described probe signal line one end is connected with probe, and the probe signal other end leads to circle by holding wire installing hole
Outside barrel-type casing, the gas circuit installing hole is provided with gas circuit line, and the gas circuit line one end is inserted into inside cylindrical shell,
The gas circuit line other end connection vavuum pump, is mounted on sealing ring, to ensure circle in holding wire installing hole and gas circuit installing hole
Sealing property inside barrel-type casing.
The gas circuit line long enough of the present invention, disclosure satisfy that when any position is layouted, and vacuum pump operation is convenient, such as exist
Eminence is layouted, and vavuum pump just may be completed in terrestrial operation.Vavuum pump adopts small portable vavuum pump, in order to carry,
When vacuumizing, switch is turned clockwise, during recovery, operation counterclockwise.Spring is taken to connect because probe is connected with housing,
So after evacuation, due to spring pressure so that probe can be close to the shell of the gas-insulating and fully-enclosed combined electrical apparatuses of SF6,
Meet test request.
When in use, bottom is simultaneously arranged in the position to be detected of GIS device to the present invention by a personal hand-held cylindrical housing
On, another one man operation minipump carries out vacuumizing process, so that probe tightly adsorbs in GIS device, so as to
Ensure the reliability of detection.
It is emphasized that embodiment of the present invention is illustrative, rather than it is determinate, therefore present invention bag
The embodiment for being not limited to described in specific embodiment is included, it is every by those skilled in the art's technology according to the present invention scheme
The other embodiment for drawing, also belongs to the scope of protection of the invention.
