Embodiment
Below in conjunction with embodiment and accompanying drawing the electric automobile motor test of the utility model is made detailed description with DC control system.
As shown in Figure 1; The electric automobile motor test of the utility model is used DC control system; Comprise: air-break 1, first D.C. contactor 2, 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 said air-break 1 connects first D.C. contactor 2 and second D.C. contactor 3 successively, a parallelly connected resistance R on described first D.C. contactor 2; The power output end of said 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 first D.C. contactor 2 through the switch contact K of electric machine controller 9, and connects the dc supply input of second D.C. contactor 3, local signal lamp 6 and remote signal lamp 7 respectively through Long-distance Control button 5, and described direct-current switch power supply 8 is switch contact K and the Long-distance Control buttons 5 that connect electric machine controller 9 through terminal strip 4 respectively.The negative pole of said direct-current switch power supply 8 connects the negative pole of first D.C. contactor 2, second D.C. contactor 3, local signal lamp 6 and remote signal lamp 7 respectively.
First D.C. contactor of being selected for use among the utility model embodiment 2 and the model of second D.C. contactor 3 are EV250.The model of air-break 1 is NM1-225S/3300.
The utility model electric automobile motor test is with in the DC control system: use DC voltage from the anodal introducing test of bus, through air-break, behind first D.C. contactor and second D.C. contactor, output to the anode of electric machine controller.
Adopt remote switch manually to control the break-make of busbar voltage, need closure during test, manual disconnecting circuit in emergency circumstances, the safety of warranty test personnel and equipment.First D.C. contactor and resistance have been formed the part that powers in advance; The loop that powers in advance that is used for the high-voltage motor controller; Guarantee that electric machine controller can not make the components and parts punch through damage because of high voltage during powering on; Reserve pair of contact in the 24V current supply circuit of the first D.C. contactor coil, export terminal strip to, be used to be connected to electric machine controller.Second D.C. contactor is used for the closure and the disconnection of testing crew Long-distance Control busbar voltage; Reserve pair of contact in the 24V current supply circuit of the second D.C. contactor coil; Be connected to the Long-distance Control button, pass through the break-make that the Long-distance Control button gets final product long-range realization busbar voltage to loop between electric machine controller during test.
Switching Power Supply is used for the power supply to first D.C. contactor, second D.C. contactor and two pilot lamp, and the 24V output line of Switching Power Supply is connected to terminal strip, being connected of convenient and other device electricity consumption loop.Long-distance Control button and remote signal lamp are formed the remote switch device, can be used for the closure and the disconnection of Long-distance Control electric machine controller busbar voltage during test.The local signal lamp is used on DC control system, showing the break-make of busbar voltage, plays warning function, prevents testing crew generation Danger Electric shock risk.
Because the DC bus-bar voltage of electric machine controller has the branch of high voltage and low-voltage, high voltage is imported regular meeting often and is raised too fastly because of the voltage of system moment, causes damage of components such as electric capacity.And in the used for electric vehicle electric machine controller not integrated this circuit function, and all adopt external module to realize, so the utility model electric automobile motor test is provided with the part that powers in advance with DC control system, make an experiment in order to the high-voltage motor controller.Low pressure controller can make it be in the attracting state that powers on always, thereby skip this function through the power switch of short circuit D.C. contactor coil.
As shown in Figure 2, the part that powers in advance of the utility model is: when the high-voltage motor controller makes an experiment, at first behind the 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; Electric current gets into second D.C. contactor through resistance R behind the air-break switch at this moment, thereby gets into electric machine controller; Resistance R plays the dividing potential drop effect at this moment, reduces the impact of high pressure to components and parts in the electric machine controller.When electric machine controller detects the voltage that inserts electric machine controller and slowly rises to required voltage; The switch contact K that closed electric machine controller provides, thus the coil of the D.C. contactor of winning is powered on, thus connect the contact of first D.C. contactor; The short circuit non-essential resistance; After this, external high pressure all is loaded into the positive and negative both sides of electric machine controller, electric machine controller operate as normal.
