Abstract
The utility model belongs to the technical field of junction boxes and in particular discloses a power line junction box. The utility model adopts the technical scheme that the power line junction box comprises a box door and a box body, wherein a wire inlet and a wire outlet are formed on the box body; an inlet wiring column and an outlet wiring column are arranged on the box body; and a non-fuse knife switch is arranged between the inlet wiring column and the outlet wiring column. The knife switch replaces a wire for direct shunting, and a disconnection point is arranged between the inlet wiring column and the outlet wiring column; when all low-level loads are opened, the non-fuse knife switch can be turned off, an obvious disconnection point is formed, and the power failure range is narrowed; and when the loads are subjected to electric leakage or short circuit and the whole distribution room trips, power can be transmitted in branching and regional modes, and time for failure searching is shortened.
Description
Technical field
The utility model belongs to the coupling box technical field, particularly a kind of power circuit coupling box.
Background technology
Power circuit demand circuit coupling box under drawing from transformer is divided into a plurality of zoness of different, and the coupling box that uses at present mainly adopts the aluminium displacement to do branch joint for lead, only plays the electric energy effect that distributes on the line; When line fault or other situation take place and need have a power failure to this zone in a certain specific region; Must stop the upper level power supply earlier, coverage is bigger, occurs dispute and unnecessary trouble sometimes; And after the power supply disconnection, breakpoint is not obvious.
The utility model content
The technical problem that the utility model solves just provides that a kind of scope of cutting off the power supply is little, breakpoint obviously, shorten and search the power circuit coupling box of fault time.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Comprise chamber door and casing, described casing is provided with incoming line and line outlet, and said casing is provided with into binding post and goes out binding post, advances binding post and go out to be provided with between the binding post to have or not the fuse disconnecting link said.
The power circuit coupling box that the utility model provided is compared with prior art and is had the following advantages: one of which, owing to comprise chamber door and casing, described casing is provided with incoming line and line outlet; Said casing is provided with into binding post and goes out binding post, advances binding post and go out to be provided with between the binding post to have or not the fuse disconnecting link said, adopts the substitute of disconnecting link as lead; Can directly shunt, but advance binding post and going out cut-off point is arranged between the binding post, after all drawing back subordinate's symbol load; We can draw back no fuse disconnecting link; And obvious cut-off point is arranged, and dwindle the power failure scope, when having electric leakage or short circuit, load side causes whole district's tripping operation; We can be along separate routes, the subregion examination is sent, and shortens and search fault time.
Description of drawings
Fig. 1 is the structural representation of the power circuit coupling box that the utility model provided.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the structure of the power circuit coupling box that the utility model provided is done further detailed description.
As shown in Figure 1, this power circuit coupling box comprises chamber door 1 and casing 2, and casing 2 is provided with incoming line 3 and line outlet 4, and inlet wire 5 gets into casing 2 through incoming line 3, and outlet 6 is stretched out casing 2 through line outlet 4.Casing 2 is provided with into binding post 7 and goes out binding post 8, is advancing binding post 7 and going out to be provided with between the binding post 8 to have or not fuse disconnecting link 9.Adopt the substitute of no fuse disconnecting link, can directly shunt, but advancing binding post 7 and going out between the binding post 8 cut-off point is arranged as lead; After all drawing back subordinate's symbol load, we can draw back no fuse disconnecting link, and obvious cut-off point is arranged; Dwindle the power failure scope; Cause whole district tripping operation when load side has electric leakage or short circuit, we can be along separate routes, the subregion examination is sent, and shortens and search fault time.
Just to the explanation of the utility model, therefore, the protection range of the utility model not only is confined to the foregoing description to the foregoing description, as long as structure is identical with the utility model power circuit coupling box, just drops on the scope of the utility model protection.
Claims (1)
1. power circuit coupling box; Comprise chamber door and casing; Described casing is provided with incoming line and line outlet, it is characterized in that: said casing is provided with into binding post and goes out binding post, advances binding post and go out to be provided with between the binding post to have or not the fuse disconnecting link said.
