In the AC system, the phase deceleration through the inverter output frequency of the inverter in the motor is achieved. Essence When the motor is required to decelerate faster than freedom, the actual speed of its corresponding speed is motivated to the speed speed. Essence
Rail transit
Transportation includes urban rail braking resistance and high -speed braking resistance, brake resistance control mechanism, ground ground resistance resistance resistance resistance resistance, pre -filled charging electrical resistance resistance and filter filter resistance resistance resistance. Urban -urban rail rail transit is rewarding the brake grid. When this energy can be absorbed and absorbed by vehicle electricity equipment, it will be
Below, asynchronous, asynchronous becoming a generator generator generator generator generator generator generator generator asynchronous mechanical mechanical energy will be converted to electrical energy and feeded back to but but but but but but to output the inverter output , Make the cut -off output deceleration and deceleration state, but the state is in the state of state, but it cannot reach the purpose of fast, fast, fast, fast, deceleration, deceleration, deceleration, deceleration and deceleration. In order to avoid avoiding the phenomenon phenomenon phenomenon phenomenon phenomenon phenomenon phenomenon phenomenon phenomenon phenomenon in the voltage type usually in the voltage type, the above phenomenon phenomenon phenomenon phenomenon phenomenon phenomenon phenomenon phenomenon usually regenerate braking circuits.
Power
Power -type resistor neutral point ground, point into ground ground ,,,,,, filtering filtering ,,,,, filtering filter resistance, high -voltage starting resistor
In the braking circuit, when the value of the flowing circuit is from time to time, it will always be turned on to be turned on to consume.
