Abstract
The utility model provides a low voltage drawing-out type switching cabinet, which is composed of a functional element cell, a bus room, a cable room that are comparted by an insulating partition plate and a metal partition plate. The utility model has the advantages that a new busbar arrangement and a new connection mode are adopted; short-time withstand current of 80 kiloampere and instantaneous short-circuit impulse current of 176 kiloampere can be born by the utility model; the operation is stable and reliable, the need of thermal stability can be satisfied; heating condition is improved, failure rate is decreased; construction, operation, and maintenance are convenient, motor control device of twenty two loops of a single cabinet is developed; the structure is compact and reasonable, the compatibility is good; the cost is low.
Description
The utility model proposes a kind of novel low pressure draw out switchgear cabinet.
Do not separated by strictness between functional unit of the prior art and bus-bar room and the cable vault, their connections each other also relatively disorderly all bring inconvenience so it gives to install and use, move, keep in repair.Wherein main bus bar places the cabinet top, is difficult to improve the moving stabilizing power of whole cabinet.
The purpose of this utility model is to overcome the defective of above-mentioned existence, proposes a kind of novel low pressure draw out switchgear cabinet.
Technical solution of the present utility model: strictness is divided into functional unit chamber (1), bus-bar room (2) and cable vault (3), all separates with insulating barrier or metal partion (metp) between (1), (2), (3).Functional unit chamber (1) is by 11 high 160mm, wide 600mm, the functional unit that dark 380mm is a base module is formed, it can be divided into the functional unit of a modulus 1/2 functional unit again, the control device of electric motor that composition is made up of 22 independent loops, can also form 3/2 according to base module, 2, the functional unit of 3 differing heights sizes, each functional unit can be equipped with the switch of different capabilities size and other according to the loop needs, the secondary device, its structure of each functional unit is a drawer, this drawer links to each other with L type branch bar in the bus-bar room by inlet wire plug on the drawer backboard, and the secondary plug on the drawer backboard goes between by cable in switching and the cable vault and terminal board with an outlet plug and links to each other.Bus-bar room (2) is made up of horizontal flat placed type main bus bar, vertical L type branch bar, wherein horizontal flat placed type main bus bar is clamped in the rear of cabinet with Bus line cramp, vertical L type branch bar is installed in the bus duct of space bar, and it is linked to each other with main bus bar by special mother line pressure joint.Cable vault (3) is that the commentaries on classics plug-in unit by the outlet of upper and lower in the cable of inlet wire and functional unit chamber (1) links to each other, and the outlet of the secondary plug in the terminal board in the cable vault and functional unit chamber (1) links to each other.
Advantage of the present utility model: 1, because whole switch cubicle is divided into functional unit chamber, bus-bar room, cable vault by strictness, easy for installation, safe in utilization, maintenance facility.2, the function of each unit is relatively independent.3, change traditional defective that bus cabinet top is arranged and connected mode is brought, adopted new busbar arrangement and new connected mode.4, the short time withstand current and the 176 kilo-ampere instantaneous short-circuit impulse currents of 80 kilo-amperes can bear in the main bus bar system.5, use novel shaped steel framework, the seriation of product, standardization are improved a lot.6, increase the sectional area of key position conductor, improved the heating condition, improved functional reliability, reduced the probability of fault.7, the space, cable vault is big, has brought convenience for construction, maintenance.8, simple in structure, compact, reasonable, interchangeability is good.9, developed the motor control unit that single cabinet can reach 22 loops.Satisfied the central controlled demand of automation.Reduce cost cost and floor space, tally with the national condition, easily promoted and use.
Accompanying drawing 1,2 is respectively that the utility model master looks, the plan structure schematic diagram.
