Embodiment
Below in conjunction with embodiment and accompanying drawing, DC control system for electric automobile motor testing of the present invention is described in detail.
As shown in Figure 1, DC control system for electric automobile motor testing of the present invention, comprise: air-break 1, the first D.C. contactor 2, the second D.C. contactor 3 and direct-current switch power supply 8, wherein, the power input connection bus positive pole 10 of described air-break 1, the power output end of described air-break 1 connects the first D.C. contactor 2 and the second D.C. contactor 3 successively, a resistance R in parallel on the first described D.C. contactor 2, the power output end of described the second D.C. contactor 3 connects electric machine controller 9, the positive pole of described direct-current switch power supply 8 connects the DC supply input of the first D.C. contactor 2 by the switch contact K of electric machine controller 9, and connect respectively the second D.C. contactor 3 by Long-distance Control button 5, the DC supply input of local signal lamp 6 and remote signal lamp 7, described direct-current switch power supply 8 is by terminal strip 4, to connect respectively switch contact K and the Long-distance Control button 5 of electric machine controller 9.The negative pole of described direct-current switch power supply 8 connects respectively the negative pole of the first D.C. contactor 2, the second D.C. contactor 3, local signal lamp 6 and remote signal lamp 7.
In the embodiment of the present invention, selected the first D.C. contactor 2 and the model of the second D.C. contactor 3 are EV250.The model of air-break 1 is NM1-225S/3300.
In DC control system for electric automobile motor testing of the present invention: from the anodal test DC voltage of introducing of bus, through air-break, after the first D.C. contactor and the second D.C. contactor, output to the anode of electric machine controller.
The break-make that adopts the manual control bus voltage of remote switch, needs closure during test, manual disconnecting circuit in emergency circumstances, the safety of warranty test personnel and equipment.The first D.C. contactor and resistance have formed the part that powers in advance, the loop that powers in advance for high-voltage motor controller, guarantee that electric machine controller can not make because of high voltage components and parts punch through damage during powering on, reserved pair of contact in the 24V current supply circuit of the first D.C. contactor coil, export terminal strip to, for being connected to electric machine controller.The second D.C. contactor is for closure and the disconnection of testing crew Long-distance Control busbar voltage, reserved pair of contact in the 24V current supply circuit of the second D.C. contactor coil, be connected to Long-distance Control button, during test, by Long-distance Control button, get final product the long-range busbar voltage that realizes to the break-make in loop between electric machine controller.
Switching Power Supply, for the power supply to the first D.C. contactor, the second D.C. contactor and two pilot lamp, is connected to terminal strip by the 24V output line of Switching Power Supply, and convenience is connected with other device electricity consumption loop.Long-distance Control button and remote signal lamp form remote switch device, can be for closure and the disconnection of Long-distance Control electric machine controller busbar voltage during test.Local signal lamp, for show the break-make of busbar voltage in DC control system, plays warning function, prevents testing crew generation Danger Electric shock risk.
Due to the DC bus-bar voltage of electric machine controller have high voltage and low-voltage minute, during high voltage input, usually can raise because of the voltage of system moment too fastly, cause the damage of components such as electric capacity.And in electric machine controller for motor vehicle not integrated this circuit function, and all adopt external module to realize, so DC control system for electric automobile motor testing of the present invention is provided with the part that powers in advance, in order to high-voltage motor controller, test.Low pressure controller can pass through the power switch of short circuit D.C. contactor coil, makes it always in the attracting state that powers on, thereby skips this function.
As shown in Figure 2, the part that powers in advance of the present invention is: when high-voltage motor controller is tested, first, after manual closing air-break switch, open external power supply, and provide electric machine controller required bus high pressure.Utilize remote switch device closed high loop, now electric current, after air-break switch, enters the second D.C. contactor through resistance R, thereby enters electric machine controller, resistance R now plays dividing potential drop effect, reduces the impact of high pressure to components and parts in electric machine controller.The voltage that access electric machine controller detected when electric machine controller is while slowly rising to required voltage, the switch contact K that closed electrical machine controller provides, thereby the coil of the first D.C. contactor is powered on, thereby connect the contact of the first D.C. contactor, short circuit non-essential resistance, after this, external high pressure is all loaded into the positive and negative both sides of electric machine controller, and electric machine controller is normally worked.
