Description
Technical field
The present invention relates in a kind of low-voltage cabinet installation system and line method more particularly to low-voltage cabinet is secondary summarizes terminal
Offline installation system and offline line method, belong to controller switching equipment technical field.
Background technique
The main function of low-voltage cabinet is opened and closed, is controlled during electric system carries out power transmission and distribution and electric energy is converted
System and protection electrical equipment can be applied to power plant, substation, rail traffic, data center, petrochemical industry, industrial enterprise, live
The various different occasions such as residence cell.Cabinet inner part is filled by breaker, disconnecting switch, on-load switch, mutual inductor and various protections
The composition such as set.Distinguished by low-voltage cabinet cabinet type, the cabinets types such as drawout cubicle, fixed cabinet, fixed separated cabinet can be divided into, wherein drawout cubicle because
Its inner part is good every pattern, and repair and maintenance is convenient, and general interchangeability is strong, therefore use scope is most wide, and application is most universal.Drawout cubicle
General structure pattern be: cabinet forefoot area places multiple drawer loops, and the positions and dimensions of drawer body are fixed and invariable, position
Before cabinet in 600mm wide * 400mm depth region, region and user are summarized for secondary cable in remaining region, mainly cabinet rear region
Terminals.According to user's power distribution room size and outlet method requirement, the cabinet of drawout cubicle is wide and cabinet have deeply 600mm, 800mm,
The difference size such as 1000mm, 1200mm, different cabinets is wide/and cabinet can form a variety of cabinet body sizes deeply.Such as: 600mm wide * 1000
Deep drawout cubicle is drawer body in 600mm wide * 400mm depth region before cabinet, in 600mm wide * 600mm depth region is secondary after cabinet
Cable summarizes region and terminal block end；The deep drawout cubicle of 600mm wide * 1200 in 600mm wide * 400mm depth region is drawer before cabinet
Ontology summarizes region and terminal block end etc. in 600mm wide * 600mm depth region for secondary cable after cabinet.It is all at present at home
Low-voltage cabinet in, the installation site that drawout cubicle secondary terminals summarize is normally at cabinet body left rear side, close to cabinet door side, installation site
Because cabinet it is wide/cabinet is deep different due to changes, lead to the secondary installation for summarizing terminal and summarize harness to cannot achieve the offline work of standardization
Industry, shop worker must take engineering drawing, after confirming cabinet body size, could make harness.Can not forward job, production effect
Rate is low.Further, since be easy to causeing one when a terminal also in the left rear side of cabinet, encounters the more situation in drawout cubicle circuit
Secondary line and secondary line wiring space are insufficient, and security performance is lower.
Summary of the invention
The purpose of the present invention is being directed to the secondary installation for summarizing terminal and summarizing defect of the harness line without standard, propose low
Cabinet is secondary summarizes the offline installation system of terminal and offline line method for pressure, provides standard for off-line operation, improve production efficiency with
Security performance.
The present invention solves technical problem by the following technical programs: low-voltage cabinet is secondary to summarize the offline installation system of terminal, institute
It states in low-voltage cabinet and is divided into cabinet forefoot area and cabinet rear region through drawer, drawer body is placed in cabinet forefoot area, after the drawer body
The right be enter line side, the left side is outgoing line side, and contact of the enter line side placement for fixed vertical row, the outgoing line side is by upper
To lower placement secondary terminals and a terminal, perpendicular fixed plate is fixed on the drawer body, the fixed plate is located at
Between contact and secondary terminals, one end connecting drawer ontology, the other end connects vertical row protective plate, the vertical row protective plate
The other end is fixed on low-voltage cabinet frame right as in the support bracket fastened cable support of service cable, the other end of the fixed plate
On be also connected with it is secondary summarize terminal, the secondary line of the secondary terminals connection is folded to fixed plate along cabinet rear wall, and connects along fixed plate
Enter it is secondary summarize terminal, the service cable is folded to vertical row protective plate along cable support, and along vertical row protective plate access two
It is secondary to summarize terminal.It by the secondary installation site for summarizing terminal of fixation, realizes the solidification of secondary line length, makes the secondary line that summarizes
Off-line operation standardization, is separately laid out with primary line, increases space, while, it is specified that the trend of service cable, improves work effect
Rate.
The purpose of the present invention further realizes by the following technical programs: the other end of the fixed plate turns down to be formed outward
Right angle flange, the right angle flange are equipped with two vertical rounds, the first round connection card frid, and the second round connects vertical row
Protective plate.The fixed plate is equipped with the hole for fixing secondary line.It is clamped on the clamping groove plate and secondary summarizes terminal.It is described to hang down
The other end of in line protective plate has flanging, and the flanging is equipped with the hole fixed with cable support.The vertical row protective plate
For transparent organic glass plate, plate is equipped with the hole for fixing service cable.The cable support is equipped with to be used for fixed
The hole of family cable.The contact of the fixed vertical row disposes the vertical row cover plate matched with its shape, vertical row cover plate position outside
In in the structure that fixed plate and vertical row protective plate surround.The length of the secondary line is 300mm.
The present invention further provides the secondary offline line methods for summarizing the offline installation system of terminal of low-voltage cabinet, by required two
The secondary congruence General Logistics Department, to summarize harness starting point carry out vertical direction first time bending, the length of the first time bending with
The length of secondary terminals matches, then carry out horizontal direction second of bending, the length of second of bending with it is secondary
The spacing of terminal and fixed plate matches, then carries out the third time bending of vertical direction, the length of the third time bending and solid
The length of fixed board matches, and the end for summarizing harness connection secondary is finally summarized terminal.In use, only needing offline line is complete
At the secondary terminal that summarizes install to low-voltage cabinet.
The present invention confirms cabinet body size without waiting for drawing, and secondary terminals installation can be completed and summarize, secondary terminals peace
Holding position and secondary line length solidify, not by cabinet it is wide/cabinet influences deeply；The secondary line that summarizes can realize offline work after wire length solidification
Industry, improving productivity 2 times or more.And vertical row cover plate is unified into single size, standardization level is high；Secondary terminals summarize solid
After change, wire length can shorten 1 meter more originally, greatly save conducting wire dosage.It is averaged 8 circuits/each drawer 13 by every drawout cubicle
Root secondary line is calculated, annual production drawout cubicle 6000, and conducting wire price be averaged 1 yuan/meter, year drop capital sum are as follows: 8*13*6000=
62.4 ten thousand yuan；First and second line is separately laid out, and increases user terminal wiring space, promotes security performance.
