An overview of the
Inverter control cabinet (inverter control cabinet/electrical control cabinet) can be widely used in metallurgical, chemical, oil, water, mining, building materials, motor industry pump, blower, air compressor, such as rolling mill, injection molding machine, belt conveyor and so on all sorts of medium voltage electrical equipment. Frequency conversion cabinet adopts closed cabinet structure, protection grade is commonly IP20, IP21, IP30 etc, adopting profiles skeleton, surface coating spraying, and easy to install and tank, the upper configurable busbar, inverter panel introduction to the cabinet put oneself in another's position appearance can be directly operation, can be set according to need or PC/PLC communication control of local and remote control, with functions of various intuitive display. Inverter is a special frequency conversion cabinet products, its functions and main technical parameters depend on the frequency control of motor speed with frequency converter of the specifications of the models and peripheral configuration status. Frequency converter cabinet according to different purposes and functions of its difference is very big also, each different general custom according to the mining requirement.
function
1, the power switch and protection of low frequency conversion cabinet is equipped with the molding shell are connected to the power circuit breaker, besides can accomplish connected and breaking circuit, circuit and the inverter in the event of a short circuit, overload protection. And we can cut off power supply when maintenance.
2, rev., stop frequency counter board set to start frequency conversion control function, frequency conversion stop button, used for operational control of the frequency conversion device, convenient for site operation.
3, frequency (speed) adjust the frequency counter board, set up frequency adjust potentiometer can easily manually adjust the output frequency of frequency converter, used to control the motor speed
4, header display frequency counter board to set the voltmeter, ammeter, frequency tables and all kinds of light such as the power indicator, emergency instructions, operating instructions, instructions, power frequency of the inverter input voltage, output current, output frequency and all kinds of working state monitoring.
5, a variety of control functions can be set up according to the working condition of system on the frequency counter board a variety of control buttons and growth indicators, such as forward, reverse, motor, motor speed and point move forward and inversion, manual/automatic, emergency stop, variable frequency/line frequency, PLC control, touch screen, etc.
6, equipped with peripheral equipment according to the working condition of need in the variable frequency ac input reactor installation, contained in the output reactor, dc reactor and EMI filter, brake unit, braking resistor, contactor and intermediate relay, thermal relay, programmable controller (PLC) and programmable operation terminal (GOT), electricity meter, cooling fan, etc.
