Description
Technical field
The utility model relates to a kind of converter valve, particularly about a kind of power module cascade connection converter valve.
Background technology
Be that the change of current valve body of the power module cascade connection form of core is widely used in the high voltage large capcity power electronic equipment with turn-off device IGBT (igbt) at present, but the import of voltage levels (2500V and more than) IGBT is restricted; Simultaneously, what the converter valve cabinet of existing power module cascade connection adopted usually is the frame structure of epoxy insulating board, if will satisfy the requirement of insulation coordination, must increase overall volume.So, current task is exactly: if will make the identical power model of the produced functional structure of power device that adopts low-voltage grade (1700V and following), coordination control by control system, realize the alternating voltage output more than several kilovolts, wherein the structural design of the carrier converter valve of power model is exactly the key of whole device reliability service.
Summary of the invention
At above problem, the purpose of this utility model provides a kind of power model of low-voltage grade that can make and realizes the power module cascade connection converter valve that the alternating voltage more than several kilovolts is exported.
For achieving the above object, the utility model is taked following technical scheme: a kind of power module cascade connection converter valve, it comprises the cabinet by a plurality of monomer groups one-tenth, be divided into three layers in each described monomer cabinet, each layer is provided with a removable power model, it is characterized in that: every layer is provided with a module frame in the described monomer cabinet, described power model is separately positioned in the described module frame, between each described power model, each described power model and each described monomer cabinet back form between the insulation board in air channel and all pass through the insulator support and connection.
Be provided with slide rail in each described module frame, described power model is separately positioned on the described slide rail.
The bottom of each described module frame is provided with a solidus device.
The utility model is owing to take above technical scheme, it has the following advantages: 1, cabinet of the present utility model is because the frame structure that adopts a plurality of Single Cabinets to be interconnected, and each Single Cabinet is divided into three layers, each layer is placed a power model, and all power models all pass through the insulator support and connection, so compact overall structure, neat appearance.2, the inlet wire cable that is connected to all power models of same phase in the utility model adopts two-layer tiling structure, and is fastened on this phase module base of frame, and neat rule has avoided cable to be adjacent alternate point discharge.3, therefore the utility model can mount and dismount power model easily owing to all be provided with slide rail in each layer module frame.4, cabinet of the present utility model, can be according to the number of module cascade the quantity of corresponding increase and decrease Single Cabinet, make power expansion very convenient, so the utility model can be widely used in the converter valve structure.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, the utility model power module cascade connection converter valve comprises a cabinet 1, cabinet 1 is connected to form by many groups monomer cabinet 11 according to the cascade number of power model 2, many group monomer cabinets 11 are placed side by side, see in appearance, between each monomer cabinet 11 is independently, and in inside, is communicated with between each monomer cabinet 11.All be furnished with upper, middle and lower-ranking module frame 12 for 11 li at each monomer cabinet, on two inferior horns of each module frame 12, two slide rails 121 be installed all, place a power model 2 on slide rail 121, power model 2 can slide along slide rail 121.The power model 2 of 12 li of upper, middle and lower-ranking module frames is set at A, B, C three-phase respectively in the same monomer cabinet 11, such as, setting the upper strata is the A phase, in, lower floor be respectively B mutually with C mutually; The same layer power model 2 of different monomers cabinet 11 is same phase, such as, the upper strata of all monomer cabinets 11 all is the A phase.Therefore, also be to be called inter-stage between the homophase power model 2 with layer, different layers also is to be called alternately between the out of phase power model 2,12 of homophase module frames at different levels connect by a series of inter-stage insulators 3 insulation; 12 of each alternate module frames at the same level lean on a series of phase insulations 4 insulation to connect; Also is connected between module frame 12 and cabinet top 51, the bottom of cabinet bulk 52, thereby each module frame 12 is all isolated mutually the mutually insulated that the realization power model is 2 by a series of phase insulations 4 insulation.
As shown in Figure 2, the insulation board 53 in all tangible one-tenth air channel, the rear portion of each monomer cabinet 11 is offered porose in the position corresponding with the air channel 21 of power model 2 on the insulation board 53.Insulation board 53 adopts insulator 6 support and connection with every layer of module frame 12, has increased the creepage distance of alternate power model.
Side at cabinet 1, be incorporated into one group of three-phase alternating current inlet wire 7 on each power model 2 by the external world, every group of inlet wire 7 all tiled, and be fixed on the bottom of the module frame 12 of place phase by solidus hole 8, both guaranteed that circuit was neatly clear, and avoided inlet wire 7 to be adjacent alternate point discharge again.
Cascade scale of the present utility model can design according to the requirement of operating voltage grade, be incorporated into 2 one groups of three-phase alternating current lines of each power model by the external world, for each power model 2 provides an AC power, all power models 2 are exported the alternating voltage of a required amplitude and phase angle by coordinating control in the cabinet 1.
