Abstract
The utility model relates to an arc plate of a partial discharging ultrahigh-frequency electromagnetic signal detection sensor box, which comprises an arc plate gasket, a center hole, countersunk head screws and an arc plate main body. The arc plate main body is the main body piece of the arc plate and is of an upwards bent arc-shaped plate on the whole. The arc plate gasket is arranged in the center of the upper surface of the arc plate main body. The arc plate main body and the arc plate gasket are connected together through four countersunk head screws. The center hole which runs through the arc plate gasket and the arc plate main body from the top to the bottom is arranged in the center of the arc plate gasket and the arc plate main body. The center hole is a round hole. The four countersunk head screws used for connecting the arc plate gasket with the arc plate main body can be screwed from the upper surface of the arc plate gasket and can also be screwed from the lower surface of the arc plate main body. The two ends of the countersunk head screws which are screwed are countersunk and do not protrude at all so as to avoid the impact on specific operations during equipment use. The arc plate has the advantages that the overall structure is simple, the arc plate is convenient to operate and use, a sensor can be better fit with the outer edge of the disc insulator of a gas-insulated switchgear (GIS) and the capacity of the sensor in receiving the ultrahigh-frequency electromagnetic signals in the cavity of the GIS can be improved.
Description
Technical field
The utility model relates to the outer box structure of the receiving system of gas-insulated switchgear (GIS) partial discharges fault superfrequency electromagnetic wave signal, relates in particular to partial-discharge ultrahigh-frequency electromagnetic wave signal detecting sensor box arc plate.
Background technology
At present, gas-insulated switchgear (GIS) Partial Discharge Detection is used widely in power industry.This detection at first must use transducer that GIS is carried out the electromagnetic detection of superfrequency, transducer need be pressed close to GIS disk insulator outer, because the disk insulator outer is circular, having must radian, general transducer box all is that a dull and stereotyped face is pressed close to the disk insulator outer, the not good and disk insulator applying of transducer, and it is unstable, extraneous simultaneously electromagnetic signal also can enter in the transducer along the face of pressing close to of cambered surface or transducer, is unfavorable for improving the sensitivity of transducer.Chinese patent 200910021728 discloses " a kind of ultrahigh frequency monitoring sensor of GIS partial discharge of external "; Chinese patent 94113338 discloses a kind of " method for sensing and the transducer of detected gas insulation in combined electric appliance partial discharge ".But the outer box of the transducer of being put down in writing in the existing open source information does not all have arc, can not press close to the GIS disk insulator outside effectively.
Summary of the invention
The purpose of this utility model is, overcome the deficiencies in the prior art part, a kind of partial-discharge ultrahigh-frequency electromagnetic wave signal detecting sensor box arc plate is provided, help transducer better and GIS disk insulator outer press close to, prevent that transducer from rocking or slide, simultaneously the effect that stops outside electromagnetic interference is arranged also, help improving the sensitivity of transducer.
Partial-discharge ultrahigh-frequency electromagnetic wave signal detecting sensor box arc plate described in the utility model includes arc plate pad, centre bore, countersunk head screw and arc plate main body and forms.Arc plate main body is a main component of the present utility model, and integral body is presented crooked arc, and middle position on arc plate main body is provided with arc plate pad.Arc plate main body and arc plate pad link together by four countersunk head screws, in the middle position of arc plate pad and arc plate main body, are provided with the centre bore of up/down perforation.Said centre bore is arranged to the form of positive circular hole.Connect four countersunk head screws that arc plate pad and arc plate main body are used, can adopt the form that above arc plate pad, is screwed into, also can adopt the form that below arc plate main body, is screwed into, countersunk head screw after being screwed into answers two ends to sink to, any protrusion must not be arranged, in order to avoid influence the concrete operations in the equipment use.
Partial-discharge ultrahigh-frequency electromagnetic wave signal detecting sensor box arc plate described in the utility model, overall structure is simple, easy for operation, help transducer better and GIS disk insulator outer press close to, prevent that transducer from rocking or slide, simultaneously the effect that stops outside electromagnetic interference is arranged also, help improving the sensitivity of transducer, especially solved the problem that transducer outer box can not be effectively pressed close to the GIS disk insulator outside mutually according to prior art.Because the arc plate has certain effect that stops the outside electromagnetic interference signal, helps improving the receiving ability of transducer to superfrequency electromagnetic wave signal in the GIS cavity.
Description of drawings:
Accompanying drawing 1 is the structural representation of the state of overlooking of partial-discharge ultrahigh-frequency electromagnetic wave signal detecting sensor box arc plate described in the utility model; Accompanying drawing 2 is structural representations of looking squarely state.1-arc plate pad, 2-centre bore, 3-countersunk head screw, 4-arc plate main body
Embodiment:
Referring now to accompanying drawing 1 and accompanying drawing 2, be described as follows in conjunction with the embodiments: partial-discharge ultrahigh-frequency electromagnetic wave signal detecting sensor box arc plate described in the utility model includes arc plate pad 1, centre bore 2, countersunk head screw 3 and arc plate main body 4 and forms.Arc plate main body 4 is main components of the present utility model, and integral body is presented crooked arc, and middle position on arc plate main body 4 is provided with arc plate pad 1.Arc plate main body 4 and arc plate pad 1 link together by four countersunk head screws 3, in the middle position of arc plate pad 1 and arc plate main body 4, are provided with the centre bore 2 of up/down perforation.Said centre bore 2 is arranged to the form of positive circular hole.Four countersunk head screws 3 that connect arc plate pad 1 and arc plate main body 4 usefulness, can adopt the form that above arc plate pad 1, is screwed into, also can adopt the form that below arc plate main body 4, is screwed into, countersunk head screw 3 after being screwed into answers two ends to sink to, any protrusion must not be arranged, in order to avoid influence the concrete operations in the equipment use.Partial-discharge ultrahigh-frequency electromagnetic wave signal detecting sensor box arc plate described in the utility model, overall structure is simple, easy for operation, help transducer better and GIS disk insulator outer press close to, prevent that transducer from rocking or slide, simultaneously the effect that stops outside electromagnetic interference is arranged also, help improving the sensitivity of transducer, especially solved the problem that transducer outer box can not be effectively pressed close to the GIS disk insulator outside mutually according to prior art.Because the arc plate has certain effect that stops the outside electromagnetic interference signal, helps improving the receiving ability of transducer to superfrequency electromagnetic wave signal in the GIS cavity.
