Description
Technical field
The present invention relates to a kind of power equipment, particularly to a kind of metering device attaching framework of 10kV power distribution cabinet.
Background technology
Metering device as carried out a steelyard of electricity clearing between power supply enterprise and Electricity customers, according to Shanghai Electric Power
《Power supply business detailed rules and regulations》Middle by charging electric meter, metering electric current/voltage transformer, secondary connecting wire, decompression chronograph etc.
Device definition is metering device, and these metering devices are significant to electric industry, and to the installation of user's metering device, movement, inspection
Test, remove, sealing up, breaking seal and the work such as meter wiring be all responsible for by affiliated Utilities Electric Co. it is ensured that metering device safe, can
It is one of groundwork of Utilities Electric Co. by operation.
It is the metering device attaching configuration diagram within a kind of existing 10kV power distribution cabinet as shown in Figure 1, Fig. 2 is Fig. 1 institute
Show the circuit diagram corresponding to existing power distribution cabinet.This power distribution cabinet is a kind of HXGN 12 type ring main unit.One road inlet wire of power distribution cabinet leads to
It is grounded after overcurrent fuse 1, voltage transformer 2, after another road inlet wire passes through current transformer 3, on the one hand melt via user side
Silk 4, on-load switch 5 connect to the leading-out terminal of power distribution cabinet, on the other hand also set up grounding switch 6 to be grounded；It is additionally provided with
Two groups of electrification displays 7, one connects to the connecting node of fuse 1 and inlet wire, and another is connected to on-load switch 5 and outlet
Connecting node.Wherein, this existing power distribution cabinet is that electric to incoming line cabinet and amount cabinet unites two into one, i.e. by current transformer 3, voltage
Transformer 2 and on-load switch 5 have together been arranged in an inlet wire storehouse 10.Specifically, by user side fuse 4 and voltage transformer
2 are arranged in the side in inlet wire storehouse 10, and the manipulator by current transformer 3, on-load switch 5, on-load switch and grounding switch
Handle be arranged in inlet wire storehouse 10 relative to opposite side.
The above-mentioned attaching framework of existing power distribution cabinet although very high to the space availability ratio of position in storehouse, saves cost and space,
But depth is longer, attaching, open a position inspection stream buckling, the maintenance of equipment that opens a position etc. are all inconvenient.Especially current transformer 3
Fabrication junction be downward, be especially inconvenient to install.In addition, user side fuse 4 is arranged in this same storehouse, if user side
Fuse 4 break down user be switched on cabinet door change；And for the position in storehouse of setting current transformer 3, if cannot seal
This position in storehouse can provide exercisable environment to stealing.
In addition, space is crowded in position in storehouse, if fuse breaks down（Such as arc extinguishing is unsuccessful, fuse explodes etc.）, bring disaster to
The risk of surrounding metering device, expansion accident scope, lift maintenance load.And, producer is cost-effective, does not often exist
The independent earthing bar of setting in this power distribution cabinet, but borrow the earthing of casing, do not meet regulatory requirements.Current transformer, voltage
The nameplate of transformer is subject to objective impact, can only be arranged at equipment back side, causes generaI investigation difficult.
The selection equipment producer therefore although user has the right, even and the power distribution cabinet of same model, the wiring of same electricity system,
Its internal actual attaching situation is also vary；In real work, if user uses the existing of above-mentioned attaching framework
Power distribution cabinet is it may be difficult to by the examination of Utilities Electric Co., also inconvenience is rectified and improved at the scene.
Content of the invention
It is an object of the invention to provide a kind of metering device attaching framework of 10kV power distribution cabinet, optimize connecing of metering device
Line design and installation environment, are easy to that equipment is installed and trouble shooting is it is ensured that metering device safe and reliable operation, maximum journey after putting into operation
The reduction of degree carries out the risk of stealing due to user's private opening position in storehouse.
In order to achieve the above object, the technical scheme is that provides a kind of metering device attaching frame of 10kV power distribution cabinet
Structure, enters to this position in storehouse after setting electric industry side fuse, voltage transformer and current transformer in the bin level as the electric cabinet of amount
Row seal；
Wherein, the road inlet wire making this position in storehouse connects to described voltage transformer through described electric industry side fuse, and this storehouse
Another road inlet wire of position connects to the outlet of this position in storehouse after described current transformer.
Alternatively, described current transformer is arranged in the side in position in storehouse, described electric industry side fuse and voltage transformer cloth
Be placed in position in storehouse relative to opposite side.
Alternatively, described current transformer and voltage transformer to be grounded using independent grounding copper bar.
Alternatively, in the outlet of described position in storehouse, there is a road to switch through user side fuse connected load, separately lead up to and connect
Being grounded, described on-load switch is interrelated with the switch of grounding switch for ground disconnecting link, with the control of same operation handle；Described use
Family side fuse, on-load switch, the operation handle of grounding switch, on-load switch and grounding switch, are all arranged in outside this position in storehouse
In one incoming line cabinet.
Alternatively, it is provided with an electrification display at the connecting node of the electric cabinet inlet wire of described electric industry side fuse and amount,
The connecting node of described on-load switch and incoming line cabinet outlet is provided with another electrification display.
Compared with prior art, the metering device attaching framework of 10kV power distribution cabinet of the present invention, has an advantage in that：
①：No user side fuse in the position in storehouse of the present invention, is only deposited electric industry side fuse and can be reduced with whole storehouse seal with stream buckling
Stealing risk.
②：The position in storehouse space of the present invention increases, and improves attaching environment, is easy to the inspection stream buckling information that opens a position, simultaneously full
The foot requirement of safe distance.
③：The distance between each equipment of the present invention elongates, and brings disaster to the wind of other equipment around after reducing fuse fault
Danger.
④：In the present invention, stream buckling earthing mode adopts independent grounding to lead to board ground connection, meets safety requirements.
Therefore, present invention optimizes the wiring design of user's power distribution station, be conducive to plant equipment quality control, reduce use
Electric safety and the risk of electricity consumption procuratorial work, optimize installation environment, improve work efficiency, stealing measure is taken precautions against in lifting.
