High and low voltage motor liquid resistance starter cabinet divided wound motor squirrel cage motor type and style of two different liquid starter cabinet, squirrel cage motors manufactured liquid resistance starter cabinet structure is complicated, in series with the motor stator circuit, it is better than winding liquid resistance starter cabinet expensive, the main components include two sets of high-voltage vacuum contactors, water resistance box, transmission components, the second device and so on. Wound liquid resistance starter cabinet manufacturing structure somewhat simple, the main components have a low pressure vacuum AC contactor, water resistance box, transmission components, secondary devices. Squirrel cage motor load based on the experience the majority of fans, pumps, roller presses, crushers, compressors, air compressor ....... etc. The winding motor load based on experience, mostly mill, vertical mill, hot mill, steel rolling, crushers, tear tile, hoist ..... etc. Our company is designed for motors, fans, pumps, roller presses, crushers, compressors, air compressor, mill manufacturers supporting the provision of high voltage switchgear, high and low voltage motor soft starter cabinet, into the phase detector, a capacitor compensation cabinet Professional production, OEM processing, wholesale companies. Liquid resistance starter cabinet adapt to technical requirements of an actual situation and cargo control requirements for electrical, water resistance starter control cabinet should be a small PLC (programmable logic controller), in order to ensure reliable operation of the water resistance of the initiator. 2 liquid resistance starter cabinet control cabinet should have two control modes: centralized control: the central computer ((DCS) for remote control next to the machine control: In the control cabinet can be open to stop every single motor can also be programmed to open stop Water resistance starter 3 liquid resistance starter cabinet control cabinet should be able to input and output the following signals: 3.1 Water resistance starter control cabinet receives input signals: a, receiving DCS drive: b, the host running the signal (passive signal, turn indicates that the host is running) signal output of 3.2 control cabinet should: (1) ready: Allow the water resistance starter remote (centralized) start signal (2), the alarm: When the alarm contact closure output signal requirements, no alarm contacts Disconnect. a, liquid resistance starter cabinet level is low. b, liquid resistance starter cabinet level high. c, the liquid temperature is high. (3), allows the host to start the water resistance starter normal start host meet the conditions. (4) Host starter finished water resistance starter shorting contactor is closed. (5), failure to stop for a host :( hard interlock with the main motor). fault output signal fault contact closure requirements, contact disconnected without failure. All of the above should contact passive contact, contact capacity of not less than 2A, 220V AC 4.4 Water resistance within the starter control all motor protection should be completed in the control cabinet 4.5 control cabinet should have.. "centralized - machine next to" Select Switch control various devices, thermometers, necessary lights (such as ready, start to allow the host, the host startup is completed, the police and the state of the motor, heater, etc.), the cabinet should alarm device. 4.6 lead terminals outside the control cabinet should be functional area, and there is a clear sign. 4.7 Water resistance starter shorting contactor capacity and ampacity copper motor rotor should meet voltage and current requirements, copper lead-out length, spacing should be appropriate to meet the connection three high-voltage cables needed to connect the seller should be equipped with enough bolts, nuts, lower cabinet with cable retention bracket 4.8 starter control cabinet water resistance protection grade:.. IP40 4.9 Water resistance starter control cabinet factory PLC (Siemens S7-200) should be complete within the control program.
