Abstract
The utility model relates to a kind of new Joining Structure of metal closed switch cabinet main bus bar, and this syndeton comprises: upper static contact box, sleeve pipe, bus-bar room, main bus bar; It is indoor that whole new Joining Structure is positioned at the upper bus of switch cubicle; The bottom surface of bus-bar room is fixed in one end of described upper static contact box, and the other end is fixedly connected with main bus bar; Described main bus bar laterally runs through whole bus-bar room; Casing pipe sleeve is contained in the two ends, left and right of main bus bar.The utility model syndeton adopts the phase sequence of new main bus bar and circuit breaker to arrange, and has cancelled branch bar and supplemental support, forms succinct T-shape main conductive circuit, has reduced heat generating spot, has improved the reliability of switch cubicle.
Description
Technical field
The utility model belongs to dynamo-electric manufacture field, particularly a kind of new Joining Structure of metal closed switch cabinet main bus bar.
Background technology
The main bus bar of traditional switch cabinet is generally arranged in the rear portion of cabinet, and its phase sequence is that A, B, C three-phase are arranged by upper, middle and lower; And circuit breaker polar A, B, C three-phase are arranged by left, center, right.This structure must be used branch bar transition and insulating supporting could realize main bus bar to connect with the electric of circuit breaker cart socket.Cause switch cubicle volume large, floor space is large, just very restricted in some industrial and mining enterprises' use, is unfavorable for exploiting market.
Utility model content
For overcoming above-mentioned defect, the technical problems to be solved in the utility model is to provide a kind of new Joining Structure of metal closed switch cabinet main bus bar simple for structure and stable and reliable for performance.
A new Joining Structure for metal closed switch cabinet main bus bar, this syndeton comprises: upper static contact box, sleeve pipe, bus-bar room, main bus bar; It is indoor that whole new Joining Structure is positioned at the upper bus of switch cubicle; The bottom surface of bus-bar room is fixed in one end of described upper static contact box, and the other end is fixedly connected with main bus bar; Described main bus bar laterally runs through whole bus-bar room; Casing pipe sleeve is contained in the two ends, left and right of main bus bar.
The utility model syndeton adopts the phase sequence of new main bus bar and circuit breaker to arrange, and has cancelled branch bar and supplemental support, forms succinct T-shape main conductive circuit, has reduced heat generating spot, has improved the reliability of switch cubicle.
Brief description of the drawings
Fig. 1 is the structural representation of the new Joining Structure of the utility model main bus bar.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Along with the progress of technology, modern power network is more and more higher to the requirement of appliance switch, and particularly the performance of appliance switch and size are upper, and the development of electrical apparatus industry is to be tending towards intelligent, miniaturization.Therefore manufacturing enterprise is optimized design for the arrangement of the three-phase major loop of metal closed switch cabinet, and main bus bar is moved to cabinet top, A, B, C three-phase by rear, in, front layout; Circuit breaker polar is changed traditional left, center, right arrangement, make its three-phase pole A, B, C consistent with main bus bar by rear, in, front layout, realized switch cubicle and circuit breaker and be set up at space cloth the unification that phase sequence is arranged.
A new Joining Structure for metal closed switch cabinet main bus bar, this syndeton comprises: upper static contact box 1, sleeve pipe 2, bus-bar room 3, main bus bar 4.Whole new Joining Structure is positioned at the upper bus chamber 3 of switch cubicle; The bottom surface of bus-bar room 3 is fixed in one end of upper static contact box 1, and the other end is fixedly connected with main bus bar 4.Main bus bar 4 laterally runs through whole bus-bar room 3.Sleeve pipe 2 is sleeved on the two ends, left and right of main bus bar 4.
The utility model syndeton has been saved branch bar transition and insulating supporting thereof, main bus bar directly and upper static contact box 1 overlap joint is realized and the electric connection of circuit breaker cart socket, major loop structure is simple, compact, current loop is short, heat generating spot is few, be conducive to ventilation and heat, save electric conducting material, reduce cost, improved conduction reliability.
