Duwan Environmental Rotation Grate Cleaning Machine with Matching Control Cabinet and Terminal Box Description
1Control cabinet
The field-mounted stainless steel control cabinet is specifically designed and matched for our diving motor, composed of components such as air circuit breakers, AC contactors, thermal relays, intermediate relays, and motor integrated protectors. It offers two control methods: local control and remote control, which can be switched using a changeover switch. The control cabinet is available in indoor and outdoor types, with installation options including wall-mounted and cabinet-style.
1Scope of Use
Suitable for controlling AC rated voltage of380VFrequency:50HZThree-phase squirrel-cage asynchronous motor. Power15KWThe direct start method is adopted for models and below (self-coupled voltage reduction or soft start can also be used upon customer request). The control cabinet provides protections for the submersible motor, including overload, phase loss, short circuit, water leakage, and overheating. Depending on the customer's configuration requirements, four structural forms are available: one control for one, one control for two, one control for three, and one control for four.
21. Job Conditions
l Surrounding0Air temperature at high altitudes does not exceed+40℃,0Not less than-10℃;
l Installation ground altitude not exceeding2000Rice
l Non-explosive environments; no gases, conductive dust, or other substances present that are capable of corroding metals or damaging insulation.
l Do not use in environments where conductive contamination is present or where non-conductive contamination may become conductive due to anticipated condensation.
3Performance Characteristics
l Overload protection does not activate when the controlled motor's rated current is exceeded for a long period; exceeds1.2At rated current multiple20Cut power within minutes and indicate fault signal. Immediately cut power and indicate fault signal if phase is missing.
l The motor can be stopped at both start-up and running positions.
l Available85~110%USOperates reliably across any voltage range, with its release voltage not exceeding75%USAvailable in quantities not less than20% US;
l In the event of a short circuit in the motor and its controlled circuit during startup and operation, the power supply can be instantaneously disconnected, effectively protecting electrical equipment.
l Leak protector for oil chamber water ingress30%Alarm indicator, but does not cut off power.
l Stator winding temperature exceeds125At °C, an alarm indicator will activate and the power will be disconnected if the heat protection wire is not connected or the temperature does not return.125Below 0°C, engine start is refused.
l Please refer to the electrical schematic diagram for control cabinet wiring details.
4) Please use
l Verify wiring correctness according to the electrical schematic diagram.
l Verify that the motor power matches and set the time relay and thermal relay adjustment values properly.
l Receive Operation: Close the air switch, connect the power, the indicator light illuminates, and switch the toggle switch to the receive position. Press the start button, and the blender begins to activate.
l Automatic Control: Switch the toggle switch to the automatic position to accept remote control signals for automatic operation.
2Terminal box
l According to customer requirements, configurable terminal boxes are available for intermediate connections between mixers and control rooms.
l Signal and power lines must be installed in separate conduits; they must not be mixed.
l Terminal boxes and control rooms use DC signals for long-distance transmission without signal attenuation.
