Explosion proof starter
Application
This starter is used for the large and medium-sized drive equipment in the harsh environment of the large load such as coal mine, coal separating plant and port where are filled with explosive gas (methane) and coal dust, etc. In power supply system of AC 50Hz, voltage 1140V, 660V or 380V, it can be used for soft start, current limiting start, full-voltage start, natural stop and soft stop in three-phase squirrel-cage asynchronous motor(0~400A). The starter is designed with various protection functions like phase protection, under-current and over-current protection, electronic thermal overload protection, imbalance current protection and so on.
Features
1. Uses advanced microprocessor (including inspection module, protection module and control module) which has features of advanced technology, complete function, stable performance, strong anti-interference capability and reliable operation, etc.
2. Uses advanced power electronic components to achieve double close loops control of current and speed; The system has functions of soft start, soft-stop, sudden pulse start, start inspection, RS232 communication and so on.
3. Voltage and current data of motor will be displayed.
4. With complete self-diagnose function and protection function, when it starts or stops, has protection functions of temperature, under-voltage, over-voltage, under-current, missing phase, line fault, stall, leakage, thyristor fault etc. Above protection functions ensure soft starter become more reliable when it meets various interference and fault signals come from inside or outside.
5. Alarm function corresponds with fault type, which greatly reduces the workload of maintenance and repair.
6. Simple structure, easy to install and operate. It can be controlled locally as well as remote control by programmable logic controller(PLC) or other equipments.
7. Communication interface of RS-485 or CAN is available.
