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, for attaching, the inspection stream that opens a position, presses change, the maintenance of equipment that opens a position etc. all very inconvenient.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 rules 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 purpose of this utility model 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, the technical solution of the utility model 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, controls; 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, at described electric industry side fuse, be provided with an electrification display with the connected node place of the electric cabinet inlet wire of amount, at the connected node of described on-load switch and incoming line cabinet outlet, be provided with another electrification display.
Compared with prior art, the metering device attaching framework of the utility model 10kV power distribution cabinet, its advantage is:
1.: no user side fuse in position in storehouse of the present utility model, only deposit electric industry side fuse and stream and press that become can whole storehouse seal, reduced stealing risk.
2.: position in storehouse of the present utility model 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 utility model is elongated, bring disaster to the risk of other equipment around after having reduced fuse fault.
