5t explosion-proof special usage electric locomotive was developed firstly by XEMC filled the gap of locomotive with explosion-proof special usage .divided into step-less speed regulating and step speed regulating. Thyristor chopper speed regulating was firstly used as well.
The Operating Environment:
For special explosion proof battery powered type electric locomotive.
1. The surrounding air temperature: -20±40℃
2. In most moist month, the average max, relative humidity is 95% (in the same month the lowest temperature is not higher than 25℃)
3. The site for coal mine special explosion-proof battery powered electric locomotive must be in according with the stipulations of 《coal mineral safety rule》
XK—6/90-KBT adapt to ambient condition where gas (methane) and coal exist, to haul mineral, equipments or other locomotive.
Composed by machinery part and electrical part:
1. Machinery parts include frame, running gear, double ceiling, chair, buffer, sands sprinkle, cover plank, buffer etc.
2. Electrical part include resistor, traction motor, pantograph type current collector, inverter, steerage, auto-switch, light, DC explosion-proof power meter, bolt contactor etc.
Advantages:
1. With advantages of legitimacy structure, smoothly start, power saving, explosion-proof.
2. Its major technical index measure up to the level of like products from home and abroad, honorably gained reputation from National and former Ministry of Mechanism and Ministry of Coal .In 1985, it was awarded the National Silver Prize.
3. Step speed regulating made use of battery series-parallel connection and motor series-parallel connection, tamper magnetic –field.
4. When speed at 7th step, it performed stable and smooth starting.
5. Trustingly quality and explosion function, simple structure, easy to maintenance with good reputation from users.
