On the box body of described control box, also comprise handle.
Described radiator is water-filled radiator, and described radiator also comprises:
Interface, for connecting coolant pipe, imports or derives cooling fluid;
Pilot pin, is connected with interface for direct coolant pipe.
Described control box comprises circuit socket, and described circuit socket is arranged in the direction contrary with heat sink interface.
Described radiator also comprises temperature relay, and described temperature relay is for power-off when radiator temperature overruns.
Described current transformer also comprises guard beam, and described guard beam setting is arranged on the both sides of IGBT.
Described current transformer connects Support Capacitor.
As seen through the above technical solutions, the beneficial effect that the utility model exists is: the structural configuration of current transformer is more reasonable, can realize installation and removal IGBT and busbar in the situation that not removing radiator, has facilitated maintenance or the replacing of IGBT and busbar; Drive circuit and pulse control circuit have been encapsulated in totally enclosed control box and can either protective circuit have also avoided emc issue; Make control box be directly installed on the radiating effect that can improve control box on radiator; Described current transformer removes the volume and weight that Support Capacitor can reduce current transformer significantly.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1～2 are converter structure schematic diagram described in the utility model embodiment.
Embodiment
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
In the middle of current transformer described in the utility model, changed the structural configuration of traditional current transformer, no longer radiator has been placed in to the bottom, but in the middle of radiator is placed in, IGBT and busbar are arranged in a side of radiator, control box is arranged in the opposite side of radiator.
Shown in Fig. 1～2, it is a specific embodiment of current transformer described in the utility model.Radiator described in the present embodiment 101 is template, comprises the first side and the second side.With reference to Fig. 1, be the end view of described current transformer, in Fig. 1, the below of radiator 101 is the first side, top is the second side.
In the present embodiment, described radiator 101 is water-filled radiator, so described radiator 101 comprises interface 1011, for connecting coolant pipe, imports or derive cooling fluid; Pilot pin 1012, is connected with interface for direct coolant pipe.Fig. 2 is the vertical view of described current transformer, and interface 1011 is shown in Figure 2 with pilot pin 1012.Described radiator 101 also comprises temperature relay, and described temperature relay is for power-off when radiator temperature overruns.
IGBT102 is arranged on the first side of radiator 101, the upper installation of IGBT102 busbar 103; As can be seen from Figure 1 be arranged in juxtaposition three IGBT102 in a row.Described busbar 103 comprises low-inductance bus 1031 and alternating current bus bar 1032; Concrete, it is upper that low-inductance bus 1031 is directly installed on IGBT102, and low-inductance bus 1031 is provided with installing hole; It is upper that alternating current bus bar 1032 is fixed on IGBT by installing hole, can be specifically to pass described installing hole by bolt in the present embodiment, and alternating current bus bar 1032 is arranged on IGBT102.In the present embodiment, also in the both sides of described IGBT102, guard beam 105 is installed, to protect IGBT102 and busbar 103, is avoided being subject to the physical damnifications such as scratch.
Shown in Fig. 2, on the box body of described control box, also comprise handle 1041, carrying and installation that handle can be convenient to described current transformer are set on box body.On described box body, also comprise circuit socket 1042, for box body internal circuit is connected with external circuit.The setting of corresponding described heat sink interface 1011 in Fig. 2, the position of described circuit socket 1042 is arranged in the direction contrary with heat sink interface 1011, because the two is distant, can avoid cooling fluid in radiator to leak control box 104 circuit and low-inductance bus 103 short circuits that cause.The position of circuit socket 1042 is marked in Fig. 2.
According to the structure described in the present embodiment, IGBT102 and busbar 103 are no longer hidden between radiator 101 and control box 104, so can directly carry out dismounting, maintenance or replacing to IGBT102 and busbar 103 in the situation that not removing control box 104, the relatively existing current transformer of structural configuration is convenient.And control box 104 is directly installed on radiator 101 in the present embodiment, radiating effect is even more ideal.In addition, the Support Capacitor of the no longer integrated IGBT of current transformer described in the present embodiment, but adopt the outside mode that connects Support Capacitor after current transformer is installed, remove the volume and weight that Support Capacitor can reduce current transformer significantly.
