Abstract

The utility model relates to an improvement of electric system and the plugged box structure of the automatic device which moves the alternating current input module in the plugged box out and changes the indirect lap mode of the cover plate and the lateral plate to comb-typed plugged connection form. The utility model eliminates the influence of alternating current input part to the other weak power loops and improves the rigidity of the electric system and the plugged box of the automatic device and the electromagnetism compatibility performance of the plugged box.

Description

A kind of subrack of Power System and its Automation equipment

Technical field

The utility model belongs to the power distribution class, is that a kind of Power System and its Automation equipment subrack structure is improved.

Technical background

The subrack of general Power System and its Automation equipment is formed the framework framework by cover plate, side plate, horizontal stripe, front panel, back panel etc., by middle mounting bar and guide rail thereof electric module is fixed in the subrack.Subrack has front inserting, rear loading type and embedded three kinds of structures, and the front inserting subrack is that module inserts from subrack is positive, the external turnover line of device is at the subrack back; The rear loading type subrack is that module inserts from the subrack back, and the external turnover line of device is on the panel of module; Embedded subrack is between front inserting and rear loading type.Subrack device front and back all can adopt whole plate structure, and whole plate and subrack can adopt with gemel version.The cover plate up and down of subrack device and left side plate adopt the fastening type of attachment of seam screw, the promptly indirect mode that overlaps, poor to Electro Magnetic Compatibility, electric contact is bad, and subrack rigidity is poor, conventional in addition ac input division branch normally is placed on subrack device inside, and it is big to take up room, and electric weak electrical loop is constituted bigger influence.

Summary of the invention

The technical problems to be solved in the utility model is the subrack that has proposed a kind of Power System and its Automation equipment for the defective that overcomes above-mentioned subrack existence, and it mainly is made of cover plate, side plate, horizontal stripe, middle mounting bar, guide rail, front panel, core bus plate, back panel, interchange module; The interchange module is not placed on subrack inside and is arranged separately in outside the back panel, and cover plate and side plate change comb shape socket connection mode into by indirect overlap joint connected mode.

Prior art exchanges input (interchange module), and this part is to be placed in the subrack device, it is big to take up room, and electric weak electrical loop is constituted bigger influence, so the utility model will exchange this part of input (interchange module) and be placed on the subrack outside, it is the back panel outside, consider that the output signal that exchanges module also is weak electric signal, disturb for reducing this weak electric signal of outer bound pair, must install nearby, hang over outward on the back panel of subrack, pass through splicing ear, insert the core bus plate, the direct access to plant of subrack back panel inside is just passed through in its output like this,, thus realized exchanging this interference source of input from installing inner separation.

Consider that electric equipment is more and more stronger to the requirement of Electro Magnetic Compatibility, the utility model has been abandoned the prior art subrack and has been adopted the mode of the indirect overlap joint of aluminium sheet and adopt anti-finger print steel plate, and initiated comb shape socket connection mode, need not to carry out surface treatment after the processing, can reduce cost greatly, reduce the environmental pollution that surface treatment brings; And, what the comb shape socket connection mode that the utility model adopts had been improved side plate and cover plate seam is connected technology and structure, has improved side plate and has contacted with the electric of cover plate, and the while also strengthened subrack rigidity, convenient for assembly, improved the Electro Magnetic Compatibility of subrack greatly.

Fig. 3 is the utility model A-A sectional schematic diagram

Fig. 4 is the utility model B-B sectional schematic diagram (a comb shaped structure enlarged diagram)

In Fig. 1 to Fig. 4: 1-exchanges module; The 2-back panel can be made the monoblock panel, is connected with subrack by hinging manner; 3-core bus plate, subrack device turnover line is realized connecting by the PCB terminal of Phoenix on the core bus plate (3) or Weidm ǔ ller; The electric module of 4-can have some groups as required, is fixed in the subrack by middle mounting bar (5) and guide rail (12) thereof; Mounting bar in the middle of the 5-, some, be used for fixing guide rail (12) and electrical module (4) and be installed on the male box frame, move by the simple of middle mounting bar (5) installation site, just can realize subrack precedingly insert, after the slotting and embedded function that patches; The 6-front panel is generally whole panel, and large-size display screen, switch, indicator light etc. can be installed, and available hinge arrangement form is fixed on the male box frame; Handle behind the 7-is modified and is used; The 8-cover plate, cover plate is two about dividing, and 90 degree flangings are made in cover plate (8) two edges punching press, and flanging is cut into the comb shape tooth sample among Fig. 2 or Fig. 4; The 9-side plate divides two of left side plates, and side plate (9) two edges surface punching press is up and down made several convex slots as Fig. 2 or Fig. 4 sample; The 10-front handlebar, fixedly subrack is used; The 11-horizontal stripe, aluminium alloy system is used to strengthen the bonding strength of cover plate (8) and side plate (9), and fixed front panel (6), back panel (2) etc.; The 12-guide rail is used for electric module plug guiding and location.

Embodiment

90 degree flangings are made in cover plate (8) two edges punching press up and down earlier, and flanging is cut into comb shape toothing (as Fig. 2, shown in Figure 4); Again with left side plate (9) up and down the two edges punching out become as shown in Figure 4 convex slot; Then the comb shape tooth insertion side plate (9) at cover plate (8) edge is gone up in the convex slot of lower limb, made cover plate (8) and the firm male box frame of left side plate (9) composition up and down.Horizontal stripe (11) is further reinforced male box frame; With hinge front panel (6) and back panel (2) are fixed on the horizontal stripe (11) of forward and backward of subrack again; Again core bus plate (3) is fixed in the subrack, with guide rail (12) different electrical module (4) is fixed on subrack inside with middle mounting bar (5); To exchange the outer outside that hangs over back panel (2) of module (1) again.

Claims

1, a kind of subrack of Power System and its Automation equipment, it is by cover plate (8), side plate (9), horizontal stripe (11), middle mounting bar (5), guide rail (12), front panel (6), core bus plate (3), back panel (2) and exchange module (1) and constituted, it is characterized in that exchanging module (1) and be placed in back panel (2) outside separately, cover plate (8) adopts comb shape socket connection mode with side plate (9).
