Product introduction ' The power size can be customized according to customer's requirement) PRT series the intersection of high-power and the intersection of high precision and programmable two-way the intersection of battery and group test apparatus is one high the intersection of power and the intersection of factor and the intersection of high precision and programmable IGBT type direct current source. Adopt the whole numerical control, control the high, response speed of the precision quickly, output the adjustment range widely. Extensively suitable for battery group's charging and discharging testing, electric electron in field of testing etc.. In the new energy trade tests,
The system adopts AC-DC, DC-DC to vary framework of two grades bidirectionally, the steady generatrix voltage that can be effective is dashing for ward the fluctuation with hour, thus improve the dynamic response time that the complete machine exported. AC-DC varies and adopts four quadrant SVPWM technology bidirectionally, energy flows bidirectionally, the power factor is up to more than 99%, incorporated into the power networks small harmonic pollution. DC-DC varies and adopts the high-frequency circuit bidirectionally, export and respond to it fast, the voltage 50~1000V of the output is adjustable. The characteristic of the products is as follows:
l Adopt two grades to vary, IGBT circuit way, pure digitization is controlled, technology leads;
l The intersection of circuit and structure adopt the intersection of three-phase and PWM commutate against turn + DC/DC into, vary pairs of grades of circuit bidirectionally, can realize wide range direct current pigeonhole and precision high responding to soon dynamically;
l Range 50V 1000V of the direct-flow output voltage;
l The passway of unit 2 is controlled independently, support the passway to connect in parallel, support the unit to connect in parallel;
l The high-efficient worker isolates the voltage transformer frequently, the direct-flow side battery is isolated with exchanging the electric wire netting of side each other;
l The liquid crystal touch-sensitive screen shows controlling, interface of many kinds of communication;
l Allocate multiple functional getting on the location machine software, easy to operate, the function of testing, supporting simulation of international major operating mode, data storing, data contours such as FUDS\SFUDS\DST,etc. to deal with etc. that have programming, help users operate greatly;
l The agreement is open, support third party's instruction control.

Second, systematic scheme tests the power battery group of the apparatus tests the demand to customer's battery, available our company PRT32250 apparatus of high-power and machine export. Test entirely the concrete scheme of the system is as follows:

Operation principle is as follows:
When battery charge, two No. three phases exchange, input, through isolate switch, worker isolate voltage transformer frequently AC-DC vary three-phase PWM commutate to direct-flow bus bar isolate, the direct-flow generatrix voltage controls direct-flow output voltage, electric current of two routes to charge battery group separately through two No. DC-DC inverter;
When battery discharge, DC-DC inverter step up to direct-flow bus bar group's voltage of the battery, AC-DC inverter goes against to turn into technology and invert the direct-flow generatrix voltage the alternating current through the three-phase complete bridge, and then present into the electric wire netting after straining the wave, worker to isolate frequently? ? ?
The system supports 2 No. of direct current, No. 3 or No. 4 to export in parallel.
Users control the programming control apparatus to run through controlling terminally, the apparatus controls information such as battery group's voltage, temperature through CAN communication!
User MES production line control systems control the terminal mutual data through communication of Ethernet and apparatus, watch-dog and battery test the course.

The main management of system Co., Ltd. of power rises in Chinese of Shanghai, the mutual inductor measures the checkout equipment, the checkout equipment of the electrical machinery, relay protection tests the apparatus, it is that one is absorbed in company that the power system develops that the power system Co., Ltd. rises in Chinese of Shanghai, based on the power undertaking, collect product development, produce and sell as an organic whole.
