During work, controller sends speed command to inverter, and direct current is changed into voltage and frequency-adjustable by inverter
Three-phase alternating current, control alternating current asynchronous traction motor is according to the curve motion of setting, and when man carrier is braked, alternating current asynchronous are drawn
Motor is operated in asynchronous generating operating mode, and the kinetic energy of train is changed into power consumption in braking resistor.Primary electrical system passes through
The bouble-bow head of pantograph introduces power supply from stringing net, and inverter is supplied by diode and breaker, and diode is by pantograph
Bouble-bow head lead keep apart, it is to avoid after Dan Gong fractures, stringing net is connected power supply short circuit with car body, cause stringing net lose
Electricity.
Braking control system is to install exhaust and brake system additional on each man carrier, and manned vehicle exhaust back brake watt passes through braking
The pressure of cylinder is to wheel braking, and driver controls braking electromagnetic valve by brake switch, come control exhaust and brake system to gas and
Degassing function.Time-delay relay is additionally provided with braking control system, when failure is braked（Failure braking refers to that man carrier goes out
Now die or gas leakage, cause failure caused by man carrier self-actuating brake, break down braking when, the corresponding pressure of man carrier after
Electrical equipment will be acted, and normally-closed contact closure connects relay K1 coils, and the relay K1 closing of contact connects the control of inverter
Tubulation pin, inverter will controlled motor ramp to stop), man carrier braking can solve rear man carrier very well to direct current
The shock of locomotive.
Brake fade warning device is to install pressure switch additional on the checking cylinder pipeline in exhaust and brake system, works as braking
Air pressure reaches setting pressure after magnetic valve is connected, and brake shoe is separated with wheel, while pressure switch is acted, signal is passed to inverse
Become device and indicator lamp, inverter allows work, and malfunction indicator lamp is extinguished.If man carrier braking does not work, pressure switch is motionless
Make, the closing of contact, then malfunction indicator lamp is bright, and locomotive failure indicator lamp is bright, point out driver to check and fix a breakdown.
The distance of mine coal identity distance well head is up to ten to two ten kilometers, with average speed per hour in 10.8Km/h, adds to arrive at a station and stops
Car waiting time, personnel need to spend 5 hours or so into and out of well head.Use personnel after high speed manned train pull-in control system
Need to spend 3 hours or so into and out of well head, saved the working time of 2 hours.Simultaneously solve resolve bow ground connection cause stop
Electric fault, train operation safety and reliability also solves shock of the rear man carrier to direct-current electric locomotive, improves the comfortable of seating
