Device is two independent components and is also accompanied by many electric components, needs sufficiently large space to be placed, causes existing
Metering cabinet volume it is big, occupied area is more, is unsuitable for applying the environment in nowadays land used anxiety, and above-mentioned component is placed in together
One chamber, internal component and connection electric wire are staggeredly complicated, extremely influence maintenance and inspection in the future.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of small in size and internal clean and tidy batch meter.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of metering cabinet, including cabinet body and cabinet door, the intracorporal chamber of cabinet are divided into interstar connection room, measuring room and meter room,
The measuring room is built-in with the combined instrument transformer for realizing metering, the primary connection end of the combined instrument transformer and secondary connection
End is located in interstar connection room, and the incoming line penetrated for high-tension cable is equipped in interstar connection room, is equipped with line outlet, secondary connection in measuring room
End is electrically connected display continuous data with the indoor ammeter of ammeter.
The measuring room is also built-in with HV live displaying sensor and arrester.
The combined instrument transformer has closing shell, and shell is provided with transformer oil to zero in combined instrument transformer
Part insulate.
Each chamber is equipped with cabinet door, and door lock seal is also equipped in the cabinet door.
The beneficial effects of the utility model are: the utility model carries out the meter of electric energy by combined current voltage transformer
Amount, greatly reduces the placement space and volume in metering cabinet, cabinet body chamber is divided into interstar connection room, measuring room and meter room, to each
Electric component carries out unified classification, places, and wherein the wiring of electric component is carried out in interstar connection room in metering cabinet, electric component
Electrical connection it is clearly clear, it is convenient that the maintenance and inspection of metering cabinet are maintained in the future.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model cabinet body chamber interior；
Fig. 3 is the structural schematic diagram of the utility model combined instrument transformer.
Specific embodiment
Referring to Fig.1, a kind of metering cabinet of Fig. 2, including cabinet body 1 and cabinet door 2, in chamber be divided into interstar connection room 11, metering
Room 12 and meter room 13, measuring room 12 are built-in with combined instrument transformer 2, the HV live displaying sensor 3 for carrying out electrical energy measurement
With arrester 4, combined instrument transformer 2 is the combination of current transformer and voltage transformer, to the metering that electric energy carries out, is subtracted significantly
Placement space and volume, HV live displaying sensor 3 in few metering cabinet can clearly distinguish each phase of combined instrument transformer 2
The working condition of line, arrester 4 is in parallel with the end of incoming cables of combined instrument transformer 2 and carries out overvoltage protection；Combined instrument transformer 2
Primary connection end 21 and secondary connection end 22 are located in interstar connection room 11, and the incoming line penetrated for high-tension cable is equipped in interstar connection room 11
5, measuring room 12 is interior to be equipped with line outlet 6, and high-tension cable is electrically connected with primary connection end 21, then is separated from the leading-out terminal of mutual inductor 2,
It is pierced by by the line outlet 6 of measuring room 12, combined instrument transformer 2 measures the Current Voltage of high-tension cable, then passes through two
Secondary terminals 22 are electrically connected display continuous data with the ammeter in meter room 13, and wherein the wiring of electric component exists in metering cabinet
Interstar connection room 11 carries out, and the electrical connection of electric component is clearly clear, convenient to maintain in the future the maintenance and inspection of metering cabinet.
As a preferred embodiment of the present invention, the combined instrument transformer 2 of this measuring room is oil immersed type insulation, is had logical
It crosses full welded closure shell 21 to insulate to the electrical component inside mutual inductor equipped with transformer oil, closing shell 21 can be effective
The case where preventing oil leak；Even if, can be with Recycling after 2 end-of-life of combined instrument transformer of oil immersed type.Each chamber is equal
Equipped with cabinet door 7, facilitates staff to enter and carry out maintenance and inspection and maintenance, be also equipped with door lock seal 8 in cabinet door 7, prevent illegal
Personnel are to the behaviors such as progress stealing electricity destruction in measuring room.
The utility model is small in size, internal clean and tidy, facilitates and carries out maintenance and inspection and maintenance, is suitable for various needs and carries out electricity
The occasion of meter amount.
