Description
Technical field
The utility model is related to digital transformer substation, more particularly to a kind of electronic transformer collector means for anti-jamming.
Background technology
The collected electric current of electronic mutual inductor or voltage are transferred to after being come out from mutual inductor ontology by small signal-wire
Collector converts the electrical signal to optical signal by the photoelectric conversion module of collector, is used to combining unit.
In present substation project configuration, collector is all integrated in special metallic shield terminal box, the metal box
It is directly mounted on the GIS babinets for closing on electronic mutual inductor.Due to the installation requirement of GIS cabinets to be matched, in metallic wiring box
Space is relatively narrow, when Substation Operating, switching overvoltage is will produce on GIS shells, due to not enough electric equipment compartments
Gap and creepage distance, this transient overvoltage enter collector by coupling or pathway, and collector is caused to damage or have
Instantaneous abnormal collection capacity occurs, and seriously affects equipment safety.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of electronic transformer collector means for anti-jamming, acquisition
Device will not can be collected correct signal by electromagnetic interference.
The purpose of this utility model is achieved through the following technical solutions：
Electronic transformer collector means for anti-jamming, including the electronic mutual inductor that is installed on GIS babinets, the electricity
Minor mutual inductor is connected by the secondary singal line with shielded layer with a prefilter, and the prefilter is set with collector
It sets in a metallic shield babinet, the prefilter is connected with collector, and the collector is exported signal by optical fiber,
The metallic shield babinet is installed on the ground by holder, and the metallic shield babinet is opened and closed by cabinet door, the secondary letter
Number line shielded layer two-terminal-grounding is provided with secondary singal line on the metallic shield babinet and penetrates hole.
Further, the metallic shield babinet is made of aluminium.
Further, the cabinet door inner circumferential is provided with sealing ring.
Further, it is provided with indicator light on the metallic shield babinet, the indicator light is connected with collector.
Further, the holder by the steel or aluminium of antirust treatment by being made.
The utility model has the beneficial effects that：
The electronic transformer collector means for anti-jamming of the utility model, by far from GIS babinets, reducing collector
Influence of the disconnecting switch divide-shut brake instantaneous pressure electromagnetic field to collector；In addition, mould will be superimposed upon when isolator operation
High pressure, high-frequency interferencing signal on quasi- signal, after prefilter substantially attenuation filter, the collected signal of collector is just
Really.

Steel material is made, and is used to support metallic shield babinet 3,2 shielded layer two-terminal-grounding of secondary singal line, is set on metallic shield babinet 3
It is equipped with secondary singal line 2 and penetrates hole 7.Metallic shield babinet 3 is made of aluminium, can shield external signal.
Cabinet door inner circumferential is provided with sealing ring, has waterproof effect after closing.
Indicator light is provided on metallic shield babinet, indicator light is connected with collector, and indicator light goes out when collector dead electricity.
Holder by the steel or aluminium of antirust treatment by being made.
The electronic transformer collector means for anti-jamming of the utility model, by far from GIS babinets, reducing collector
Influence of the disconnecting switch divide-shut brake instantaneous pressure electromagnetic field to collector；In addition, mould will be superimposed upon when isolator operation
High pressure, high-frequency interferencing signal on quasi- signal, after prefilter substantially attenuation filter, the collected signal of collector is just
Really.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
