Control cabinet maintenance control cabinet manufacturers

1. Disconnect the power supply, check whether the control cabinet frame has a reliable grounding, make the grounding resistance is greater than 4Ω.

2. control cabinet on the different nature of the voltage (DC 110V; AC single-phase 220V; three-phase AC), in the maintenance of the circuit must be clear to prevent the occurrence of short-circuit accidents.

3. control cabinet on all electrical switches, should be flexible reliable, no significant noise, safety cabinet manufacturers connecting line junction terminal should be no loose phenomenon, dynamic contacts connecting line junction at the wire should be no breakage.

4. Use soft brush blowing wind to remove the screen board plug-in all electromagnetic switch parts of the dust, check the state of the electrical switch contacts in the control cabinet, the contact situation, the coil appearance of the insulation as well as the mechanical parts of the action is reliable.

5. When replacing the fuse, make sure that the fusing current matches the current of the circuit.

PLC integrated control cabinet has protection functions such as overload, short circuit phase loss protection. It has a compact structure, stable operation complete functions. It can be combined according to the size of the actual control specification, can realize either single cabinet automatic control multiple cabinets through industrial Ethernet industrial field bus network to form a centralized (DSC) control system. PLC control cabinet can be adapted to various sizes of industrial automation control occasions. Widely used in electric power, metallurgy, chemical industry, papermaking, environmental protection, sewage treatment other industries.

PLC control cabinet can complete the equipment automation process automation control, realize the network function of the United States, stable performance, scalable, strong anti-interference characteristics, is the core soul of modern industry. PLC control cabinets, frequency conversion cabinets, etc. can be customized according to user needs to meet user requirements, can be paired with human-machine interface touch screen, to achieve the purpose of easy operation. Equipment can be more with DCS bus host computer modbus, profibus other communication protocols for data transmission; industrial control machine, Ethernet other control monitoring.

Typical applications: constant pressure water supply, air compressors, fans pumps, air conditioning, port machinery, machine tools, boilers, paper machinery, food machinery so on.
