Description
Technical field
The present invention relates to a kind of power equipment, particularly a kind of metering device attaching framework of 10kV power distribution cabinet.
Background technology
Metering device is as a steelyard that carries out electric weight clearing between power supply enterprise and electricity consumption client, according in Shanghai Electric Power " Power supply business detailed rules and regulations " by charging electric meter, for metering, the device definition such as electric current/voltage transformer, secondary connection wire, decompression calculagraph is metering device, these metering devices are significant to electric industry, and installation, movement, inspection to user's metering device, remove, seal up, break seal and show to count the work such as wiring and be all responsible for by affiliated Utilities Electric Co., guarantee that safety, the reliability service of metering device is one of groundwork of Utilities Electric Co..
Be the metering device attaching configuration diagram of existing a kind of 10kV power distribution cabinet inside as shown in Figure 1, Fig. 2 is the corresponding circuit diagram of existing power distribution cabinet shown in Fig. 1.This power distribution cabinet is a kind of HXGN-12 type ring main units.Power distribution cabinet Yi road inlet wire is by fuse 1, the rear ground connection of voltage transformer 2, another road inlet wire is by after current transformer 3, the leading-out terminal that is connected on the one hand power distribution cabinet via user's side fuse 4, on-load switch 5, also arranges on the other hand grounding switch 6 and carrys out ground connection; Also be provided with in addition two groups of electrification displays, one is connected to the connected node of fuse 1 and inlet wire, and another is connected to the connected node of on-load switch 5 and outlet.Wherein, this existing power distribution cabinet is that incoming line cabinet and the electric cabinet of amount are united two into one, that is, current transformer 3, voltage transformer 2 have together been arranged in an inlet wire storehouse 10 with on-load switch 4.Concrete, user's side fuse 4 and voltage transformer 2 are arranged in to the side in inlet wire storehouse 10, and the operating grip of current transformer 3, on-load switch 4, on-load switch and grounding switch is arranged in to the interior relative opposite side in inlet wire storehouse 10.
The above-mentioned attaching framework of existing power distribution cabinet, although very high to the space availability ratio of position in storehouse, provide cost savings and space, depth is longer, presses change, the maintenance of equipment that opens a position etc. all very inconvenient for attaching, the inspection stream that opens a position.Especially the fabrication junction of current transformer 3 is downward, is inconvenient to especially install.In addition, user's side fuse 4 is arranged in this same storehouse, if user's side fuse 4 breaks down, user must open the replacing of cabinet door; And for the position in storehouse that current transformer 3 is set, if cannot can provide exercisable environment to stealing by this position in storehouse of seal.
In addition, space is crowded in position in storehouse, if fuse breaks down (such as arc extinguishing is unsuccessful, fuse blast etc.), has and brings disaster to the risk of metering device around, and expansion accident scope, promotes maintenance load.And producer is cost-saving, often independently earthing bar is not set in this power distribution cabinet, but uses the earthing of casing, do not meet code requirement.The nameplate of current transformer, voltage transformer is subject to objective impact, can only be arranged at the equipment back side, causes generaI investigation difficulty.
Therefore, although user has the right to select equipment manufacturer, even and the power distribution cabinet of same model, same electric system wiring, its inner actual attaching situation also varies; In real work, if user uses the existing power distribution cabinet of above-mentioned attaching framework, by the examination being difficult to by Utilities Electric Co., also inconvenience is rectified and improved at the scene.
Summary of the invention
The object of the present invention is to provide a kind of metering device attaching framework of 10kV power distribution cabinet, optimize wiring design and the installation environment of metering device, the equipment of being convenient to is installed and trouble hunting, metering device safe and reliable operation after guaranteeing to put into operation, farthest reduces the risk of carrying out stealing due to user's private opening position in storehouse.
In order to achieve the above object, technical scheme of the present invention is to provide a kind of metering device attaching framework of 10kV power distribution cabinet, in the bin level as the electric cabinet of amount, this position in storehouse is carried out to seal after electric industry side fuse, voltage transformer and current transformer are set;
Wherein, make this position in storehouse Yi road inlet wire be connected to described voltage transformer through described electric industry side fuse, and another road inlet wire of this position in storehouse is through being connected 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, and described electric industry side fuse and voltage transformer are arranged in relative opposite side in position in storehouse.
Alternatively, described current transformer and voltage transformer adopt independently grounding copper bar to carry out ground connection.
Alternatively, in the outlet of described position in storehouse, You Yi road is through user's side fuse connected load switch, and the grounding switch of separately leading up to carrys out ground connection, and the switch of described on-load switch and grounding switch is interrelated, with same operating grip control; The operating grip of described user's side fuse, on-load switch, grounding switch, on-load switch and grounding switch, is all arranged in an incoming line cabinet of this position in storehouse outside.
Alternatively, be provided with an electrification display at described electric industry side fuse with the connected node place of the electric cabinet inlet wire of amount, be provided with another electrification display at the connected node of described on-load switch and incoming line cabinet outlet.
Compared with prior art, the metering device attaching framework of 10kV power distribution cabinet of the present invention, its advantage is:
1.: no user side fuse in position in storehouse of the present invention, only deposit electric industry side fuse and stream and press that become can whole storehouse seal, reduce stealing risk.
2.: position in storehouse of the present invention space increases, and has improved attaching environment, being convenient to open a position checks that stream presses change information, met simultaneously safe distance requirement.
3.: distance between each equipment of the present invention is elongated, bring disaster to the risk of other equipment around after having reduced fuse fault.
4.: in the present invention, stream is pressed and become the logical board ground connection of earthing mode employing independent grounding, meets safety requirements.
Therefore, the present invention has optimized the wiring design of user's power distribution station, is conducive to producer's equipment quality control, has reduced the risk of Electrical Safety and electricity consumption procuratorial work, has optimized installation environment, increases work efficiency, and promotes the stealing measure of taking precautions against.
