AC transformer for mining equipment

1.IGBT driving mould 2.polypropylene film capacitance 3.big power IGBT electrical parts

Technology features of transformer

1.Using IGBT driving mould, polypropylene film capacitance, big power IGBT electrical parts.

2.Power supply mould using big power, wide range voltage and wide range of acceptable temperature, the environment temperature applied in mine industry is -40°C~+50°C, the voltage float range is -40%~+30%.

3.Circuit control PCB board totally developed by ourselves which have independent knowledge property, function mould totally designed by ourselves which can well adapt the special environment of mine equipment, the new development technology effect AC speed control applied to mine equipment speed control of electrical mechanism, which is a breakthrough in state independent knowledge property.
