Abstract
The utility model discloses a heavy current draw-out type switch cabinet comprising a general cabinet, a horizontal busbar frame arranged in the general cabinet and positioned on an upper position of the general cabinet, a busbar frame arranged below the horizontal busbar frame, a main busbar arranged on the horizontal busbar frame and the busbar frame, and a support piece arranged in the general cabinet and positioned in a middle position of the general cabinet and used for supporting the main busbar; and the support piece is provided with an insulator. A series of problems of the heavy current draw-out type switch cabinet are well solved; overhigh cabinet body temperature caused by eddy current problem is reduced; and overlarge system noises and overlarge losses are reduced.
Description
Technical field
The utility model relates to a kind of big electric current draw out switchgear cabinet.
Background technology
0.4kV big electric current draw out switchgear cabinet, purposes is wider in the bigger factory of some electricity consumption, real estate, and existing standard 0.4kV draw out switchgear cabinet is in the system of big electric current, and the problem that produces eddy current is not well solved.Because electric current goes in the system of 4000A～6000A, eddy current problem to system to influence meeting obvious especially, a series of problems such as can produce cabinet temperature height, noise is big, loss is big.
The utility model content
Main purpose of the present utility model is to provide the big electric current draw out switchgear cabinet of a kind of effective inhibition temperature rise, noise and loss.
For addressing the above problem, the utility model adopts following technical scheme: a kind of big electric current draw out switchgear cabinet, comprise general cabinet, and be arranged in the general cabinet and be positioned at the horizontal bus frame of general location cashier's office in a shop, and be arranged on the bus frame of horizontal bus frame below, and be arranged on main bus bar on horizontal bus frame and the bus frame, and be arranged in the general cabinet and be positioned at a part general cabinet centre position, that be used for supporting main bus bar, described part is provided with insulator.
Further, described main bus bar is connected with the inlet wire bus, and described inlet wire bus is connected with the transition bus.
Further, described general cabinet lower position is equipped with the screen space bar.
Further, described main bus bar is provided with cable bearer and fixes.
The beneficial effect of the big electric current draw out switchgear of the utility model cabinet is: well solve a series of problems that big electric current draw out switchgear cabinet exists, reduce problems such as the cabinet temperature that produces because of eddy current problem is too high, system noise is excessive, loss is big.
Description of drawings
Fig. 1 is the generalized section of the big electric current draw out switchgear of the utility model cabinet;
Fig. 2 is the end view of the big electric current draw out switchgear of the utility model cabinet.
Embodiment
See also illustrated in figures 1 and 2, a kind of big electric current draw out switchgear cabinet of the present utility model, comprise general cabinet 1, and be arranged in the general cabinet 1 and be positioned at the horizontal bus frame 17 of general cabinet 1 top position, and be arranged on the bus frame 18 of horizontal bus frame 17 belows, and be arranged on main bus bar 29 on horizontal bus frame 17 and the bus frame 18, and be arranged in the general cabinet 1 and be positioned at a part 24 general cabinet 1 centre position, that be used for supporting main bus bar 29, described part 24 is provided with insulator 19.
Described main bus bar 29 is connected with inlet wire bus 32, and described inlet wire bus 32 is connected with transition bus 41.Described general cabinet 1 lower position is equipped with screen space bar 49.It is fixing that described main bus bar 29 is provided with cable bearer 59.
0.4kV 304 stainless steels that the general cabinet 1 of big electric current draw out switchgear cabinet adopts are made, and change the magnadure plate at left side plate into by original A3 steel plate, reasonably controlled cost, mounting rail and strengthen a part and change to 3.0 steel plate by original 2.0, cancellation bus-bar room upside crossbeam is the interval crossed of bus string once, do not form the magnetic conductive loop of a closed loop, effectively prevent induced current and problem that the cabinet temperature that produces raises.Thereby noise and the loss of whole system have been solved.
The beneficial effect of the big electric current draw out switchgear of the utility model cabinet is: because all stud materials have been selected 304 not saturating steel matter for use, general cabinet has guaranteed the intensity of cabinet, and left side plate has adopted 5056 almag plates, and is suitable with the A3 phase-plate on the intensity; In bus-bar room, because cancellation upside crossbeam, the interval that makes the bus string cross has not had the closed loop of magnetic conduction, has all played the effect of anti-eddy current.Make under the tight prerequisite of the overall structure of the big electric current draw out switchgear of 0.4kV cabinet, played the effect of anti-eddy current, effectively suppressed temperature rise, noise and loss.
The above only is embodiment of the present utility model, but protection range of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
