Abstract
The invention discloses an arc plate of a partial-discharge sensor box for detecting ultrahigh frequency electromagnetic wave signals, comprising an arc plate spacer, a central hole, sunk screws and an arc plate body. The arc plate body is the main body of the arc plate of the partial-discharge sensor box for detecting ultrahigh frequency electromagnetic wave signals, the arc plate are wholly bent upwards, and the arc plate spacer is arranged at the center of the upper surface of the arc plate body. The arc plate body and the arc plate spacer are connected together by four sunk screws, and a central hole penetrating up and down is arranged at the center of the arc plate spacer and the arc plate body. The central hole is in shape of circle. The four sunk screws connecting the arc plate spacer and the arc plate body can be screwed in from the upper surface of the arc plate spacer or from the lower surface of the arc plate body, both ends of each screwed-in sunk screw are sunk without any protrusion so as to avoid influencing the specific operations in use process of devices. The arc plate of the partial-discharge sensor box for detecting ultrahigh frequency electromagnetic wave signals has simple integral structure and is convenient to operate and use; furthermore, the arc plate disclosed by the invention is beneficial to making the sensor greatly close to the outer edge of a GIS (Gas Insulated Switchgear) disc-shaped insulator and improving the reception capability of the sensor on the ultrahigh frequency electromagnetic wave signals in a GIS chamber.
Description
Technical field
The present invention relates to the outer box structure of the receiving system of gas-insulated switchgear (GIS) partial discharges fault superfrequency electromagnetic wave signal, relate 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 objective of the invention is to, 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 of the present invention 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 invention, 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 of the present invention, 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 of the present invention; 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 of the present invention 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 invention, 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 of the present invention, 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.
