Abstract
The utility model discloses an air switch and aviation plug combined conjunction box comprising a conjunction box body; the air switch, the aviation plug and an insulation box are arranged in the conjunction box body; the air switch is arranged on an upper row in the conjunction box body; the aviation plug is arranged on a lower row in the conjunction box body; the air switch and the aviation plug are connected through a short copper sheet and are wrapped by the insulation box; one-to-one structure or one-to-more structure can be arranged in the conjunction box body. The air switch and aviation plug combined conjunction box ingeniously solves the connection problem between prefabricated power cable and two end air switches, and realizes application promotion from DC power single end prefabricated cable to double end prefabricated cable in a power transformer station.
Description
Technical field
The utility model relates to a kind of terminal box field, and especially a kind of sky is opened and the integrated terminal box of aviation plug.
Background technology
Prefabricated cabin formula secondary unit equipment is the emphasis application that State Grid Corporation of China proposes first in standard dispensing formula intelligent substation is built, secondary device is arranged in prefabricated cabin, equipment room adopts prefabricated optical, electrical cable to connect, at utmost realize large-scale production in factory, integrated debugging, reduce field connection and debugging work, improve construction efficiency.
Prefabricated cabin formula secondary unit equipment requires standard to use the prefabricated looped cable of transformer station's AC power and the single-ended pre-fabricated electric cables of DC power supply, progressively realizes prefabricated cabin secondary connection " plug and play ".
The order of connection of tradition control cables is: in screen, device-> screen inner cable-> shields the interior device of cable between inner terminal row-> screen-> screen inner terminal row-> screen inner cable-> screen, can be by cancelling terminal board and at device place configuration pre-fabricated electric cables plug, realizing " plug and play ".
In view of the order of connection of traditional power cable is: device in moving cable-> equipment screen in open-> of sky equipment screen in common moving cable-> equipment screen between open-> of feed panel sky screen, visible, the two ends that between screen cabinet, moving cable connects are sky and open, for realizing prefabricated power cable, in prefabricated cabin, use, need to invent a kind of two and connect the empty prefabricated power cable of opening.
Summary of the invention
The purpose of this utility model is to provide a kind of sky and opens and the integrated terminal box of aviation plug.
What the utility model solved is how prefabricated power cable opens with feed panel, equipment screen two ends sky the problem being connected.
Skill scheme of the present utility model is: it comprises terminal box body, in described terminal box body, comprise that sky is opened, aviation plug and insulation booth, described sky is opened in the intrinsic upper row of described terminal box, described aviation plug is located at the intrinsic lower row of described terminal box, described sky open with aviation plug between by short copper sheet, be connected, described insulation booth parcel for outside can be " one to one " structure or " one-to-many " structure in described terminal box body.
Described " one to one " structure is that described sky is opened in the intrinsic upper row of terminal box, and described aviation plug is located at the intrinsic lower row of terminal box, and the corresponding sky of each aviation plug is opened, and by short copper sheet, connects.
Described " one-to-many " structure is that described sky is opened in the intrinsic upper row of terminal box, and described aviation plug is located at the intrinsic lower row of terminal box, and the corresponding a plurality of skies of each aviation plug are opened, and by short copper sheet, connect.
The beneficial effects of the utility model are: make full use of aviation plug and sky is opened features, by realize aviation plug and the empty centralized arrangement of opening in same terminal box, ingeniously solved prefabricated power cable and opened with two ends sky the problem being connected, retain empty be full of flexible deciliter of sufficient power supply in, realize the single-ended pre-fabricated electric cables of DC power supply transformer station in and apply to the lifting of both-end pre-fabricated electric cables.
Accompanying drawing explanation
Fig. 1 is the utility model " one to one " structural representation.
Fig. 2 is the utility model " one-to-many " structural representation.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in the figure, it comprises terminal box body, in described terminal box body, comprise that sky opens 1, aviation plug 2 and insulation booth 3, described sky is opened 1 and is located at the intrinsic upper row of described terminal box, described aviation plug 3 is located at the intrinsic lower row of described terminal box, described sky open 1 with aviation plug 3 between by short copper sheet, be connected, described insulation booth 3 parcels, can be " one to one " structure or " one-to-many " structure in described terminal box body for outside.
Described " one to one " structure is that described sky is opened 1 and is located at the intrinsic upper row of terminal box, and described aviation plug 2 is located at the intrinsic lower row of terminal box, and the corresponding sky of each aviation plug 2 opens 1, by short copper sheet, connects.
Described " one-to-many " structure is that described sky is opened 1 and is located at the intrinsic upper row of terminal box, and described aviation plug 2 is located at the intrinsic lower row of terminal box, and the corresponding a plurality of skies of each aviation plug 2 open 1, by short copper sheet, connect.
Described aviation plug 2 can be direct current aviation plug or exchange aviation plug, and described sky is opened 1 and can be opened DK or exchange sky for direct current sky and open UK.
The core number of described aviation plug 2 is not less than 2 cores.
In view of the feature of power cable ampacity much larger than general control cable, must to the core number of aviation plug 2 and plug wire diameter in addition science after calculating, determine.Generally, suggestion DC plug number is less than or equal to 8 cores.
It is 1 preposition with respect to aviation plug 2 that described sky is opened, and is the prefabricated enough spaces of front slotting mode of prefabricated power cable one end plug.
Conventional screen cabinet is general single channel to the demand of DC power supply, adopt " one to one " structure, (power cable of 12 core also for " 2-1-n " scheme, the aviation plug of 12 core, n sky opened) can meet if desired double loop power supply, can adopt " one-to-many " structure, " 4-1-2n " scheme (power cable of 14 core also, the aviation plug of 14 core, 2n sky opened).
