Why Mine Battery Locomotive Not Running after Controller Closed

Date: 11/12/2017   View: 48  Tags: Batter Locomotive Mine Locomotive Starts

Mine Battery Locomotive not walking mainly due to open circuit of electrical parts, usually familiars are found in the following six kinds of circuit: the pantograph and automatic switch off; controller should be open part of the circuit; start resistance circuit; traction motor internal circuit; motor The owner circuit ground wire open circuit.
Approach of Mine Battery Locomotive Not Running after Controller Closed
1, Exclude the pantograph off, replace the spring, so that the skateboard and the line contact well; repair the broken part of the power cord to ensure that the terminal does not loosen to ensure that the normal electric locomotive power supply;
2, Restore the normal power supply automatically switch, replace or repair burned contacts and power lines; repair terminals or magnetic coils to ensure that the control circuit voltage is normal;
3, Repair the controller should be turned on, repair the main contact or auxiliary contact off, to ensure good contact, according to the wiring diagram of the motor car repair loose broken wire;
4, Excluding start-up resistor failure, repair or replace the start-up resistor, to ensure the normal start of the electric car;
5, Repair the internal circuit of the motor, repair the internal circuit of the motor, repair the main magnetic pole or the commutated pole coil circuit, repair the connecting wire terminals to ensure that the brush and the commutator are in good contact.
