This series of combined starter is applicable to the environment where underground coal mine and surrounding medium contain methane, coal dust and other explosive mixture gases. In the power supply system with a frequency of 50Hz and rated voltage up to 1140v, multiple dual-speed motors or asynchronous motors can be controlled individually, sequentially, single-machine dual-speed, double-machine dual-speed, and any combination of control. At the same time, 127V or 220V lighting power supply is provided, and each load and power supply ine are protected; The automatic control of power supply equipment can be realized by configuring it in the mine monitoring system.
| Rated voltage | 1140V, 660V |
| Rated current | 80A, 120A |
| Standard frequency of power supply for integrated protection device | 50Hz |
| Comprehensive protection device | Long-term system |
| Altitude | Not exceed 2000m |
| Ambient temperature | -5ºC-+40ºC |
| The relative humidity of the air is not more than 95% (+25%); In the environment without strong vibration and shock vibration; In the air containing methane and coal dust, but without gas and stream that can corrode metal and demage insulation; It is installed in the flameproof cavity of flameproof cavity of flameproof feed switch. |
Module Design:
The power unit adopts modular design, with built-in (permanent magnet) vacuum contactor, current transformer,resistance and capacitance, main circuit circular quick-plug contact, control circuit quick-plug and other main components, combined with the patented push device and precision rail guide plug, the module is highly interchangeable and easy to install and maintain.
PLC Control:
It adopts PLC direct signal sampling and protection control,with high accuracy, fast speed and strong expansibility. It has multiple functions such as overload, short circuit, leakage locking, leakage protection, undervoltage, overvoltage, three-phase imbalance, gas locking, windpower locking, etc, it can also realize complex logic proaramming, data acauisition,floating point calculation, process control. networking communication and other functions.
Color Display:
Large-scale true-color display screen, dynamic picture can be edited at will, and controllogic can be combined at will. It can monitor and visually display three-phase voltage, current, insulation resistance and other parameters, as well as the operation and fault status of each circuit, and has the function of fault memory and query.
Four Remote Function:
The parameter setting can be set locally by pressing the key on the side of the screen, or can be set remotely by RS-485 interface, or Ethernet optical fiber (optional and communication with the upper computer of the monitoring system. The remote star and stop can realize the "four remote" function to achieve unattended substation.
Vacuum Breaking:
The large-capacity vacuum isolating and reversing switch is used as the breaking part of the combined switch. The mechanical reversing,vacuum breaking and rated breaking capacity can reach 4800A to solve the problem of insufficient breaking capacity of the conventional reversing switch in the coal mine.
Split Cavity Design:
The power unit of each circuit in the main chamber is designed with modular structure, and the circuits can be interchanged. The internal functional chamber is designed with independent flameproof design to enhance the flameproof performance, and the space layout is reasonable and compact, which simplifies the cable connection and wiring, saves the space occupied by the equipment, also reduces the construction cost of the distribution chamber, reduces the type and quantity of spare parts, and reduces the use cost; The combined compartment design is adopted to save space, and reliable mechanical interlocking, electrical locking, emergency stop and other devices are provided.
Safety Module:
The control circuit adopts intrinsically safe and safe module.
Explosion-proof grade:
Explosion-proof type: Exd I Mb Protection grade: IP54
