A , electrical safety requirements:

1) The control system can ensure that the supply energy of the equipment will not cause danger when an abnormality occurs, and the equipment itself will not be damaged and will not cause harm to personnel.

2) The control system is placed at a location that is easy for the operator to operate and observe. The equipment is equipped with the necessary emergency stop button according to the specific situation. The emergency stop mechanism must be self-locking. The operation color is red. If there is a contrast color, the color should be black. The operating part of the button operation switch should be a palm or mushroom head.

3) Electrical control system of the equipment: with overload protection and short circuit protection. When the line of the device hits the case, the control system cuts off the power supply to the line within 0.1 seconds.

4) For inspection, adjustment, and maintenance, it is necessary to observe the hazardous area or the production equipment that the human body needs to reach into the dangerous area, and must prevent the false start. When the equipment may endanger personal safety due to accidental starting, it must be configured with a mandatory safety guard to prevent accidental starting.

5) When the energy is accidentally cut off and then turned back on, the equipment must be able to avoid dangerous operation.

6) Adopt three-phase five-wire power supply system, and the equipment casing adopts protection and zero connection measures.

7) The motor is installed firmly, and the control requires overload, short circuit and open circuit protection, and the protection level is above IP54 .

8) When the equipment is in operation, when a component fails or is damaged, the equipment itself has corresponding protective measures, which may not cause greater damage to the equipment itself, and may not cause harm to the operator. The protection measures mainly include: action running time protection: when the actual running time of an action exceeds the normal value, it will alarm; heating temperature protection: if the normal heating or cooling time is exceeded, the alarm will not be achieved; the malfunction protection: due to The pipeline seal is not strictly pressure-relieved, and the components that should not be operated must have an alarm;

9) Measures to prevent wire wear around the outlet of the power distribution cabinet. There is no connector in the middle of the power cord.

B , control cabinet and power distribution requirements:

1) Main switch: The incoming line must be three-wire and five-wire system, that is, the three-phase power supply, the one-phase ground wire, and the one-phase neutral wire are fixed by the wiring nose. The switch specification capacity is less than the load of the sub-switch and equipment. The main switch is remote from the DC24V power supply. The main line uses AC380V or AC220V , and the control circuit uses DC24V .

2) The ground wire row and the zero wire row are marked and fixed separately, and the control cabinet door must have a cross-grounding wire.

3) The control cabinet door must be marked with the indication of each branch switch control.

4) There must be ventilation in the control cabinet (axial flow fan and inlet grille form convection), and the ventilation port has a dust filter net.

5) The lighting device inside the control cabinet must be in good condition to ensure that the door is lit, or the switch is installed to control the lighting.

6) All line traces must be standardized into the trunking, and the line numbers are marked. The line number requirement does not fade, and it matches the drawing. The wire diameter is selected appropriately, and the infrared thermometer is used to check that there is no overheating or overloading of each line.

7) Insulated shields, copper bars, etc. must be installed with insulating protective plates, anti-rat boards, etc.

8) Rubber pads with insulation grade and size must meet the safety requirements before the control cabinet.

9) For motor control mode: control system with air switch + contactor + thermal relay or motor protection switch + contactor.

10) Fixing method: The electrical components are fixed on the control cabinet with 35mm standard rails.

11) Wiring method : Fix and mark the line number with the terminal;

12) PLC part : PLC power supply has corresponding protection facilities; PLC is installed firmly and well ventilated; input and output are distinguished by two lines; there are more than 5 I/O points for standby.

13) Inverter part: The capacity is 1 level higher than the rated power of the motor ; the incoming line has a reasonable protection system;

14) Multi-core cord wiring trough is used in the cabinet; 220V and DC24V line colors are separated; the wire has a spare space in the slot; the outlet of the distribution wire is protected with rubber; the wire has a standard wire number.

15) Terminal block part: The terminal is installed at the lower end of the control cabinet, 380V and DC24V are installed separately; the power distribution cabinet and peripheral equipment are connected by aviation plug or terminal block.

16) External wire trough, standard, safe, is pressed, not deformed.

17) Cables and wires in the production line of the production line need to be routed, and the water and gas paths should be distributed reasonably.

18) The connection line number of the input and output parts of the equipment is clear, durable and easy to find on the spot; it will not be lost due to the replacement of parts;

C , component configuration requirements:

1) Regarding the selection of components, it is required to use the products of international or domestic well-known companies, and it is not allowed to use the parts that are unique to Party B (exclusive to Party B's technology) and not available to other companies.

2) The brand requirements of the components used in the equipment are as follows: (The manufacturers must configure the equipment according to the requirements of our parts)
