The requirements for mechanical power line connection mainly include the following points:
Cable selection:
Choose appropriate cables according to the voltage level of the equipment to ensure the safety and reliability of electrical wiring.
Choose appropriate cable cross-sectional area according to the working current of the equipment to avoid overload or heating of the wire.
Ensure that the insulation material of the wire sheath meets national standards and can withstand the voltage and current generated during the operation of the equipment.
Line layout:
The wires should be arranged in a suitable path, away from high temperature, humidity, and easy to wear areas to avoid electrical faults.
Appropriate protection measures should be taken for the wires, including the use of cable troughs, pipes or metal sheaths, etc., to protect the wires from external damage.
Wiring specifications:
Reliable quality terminals should be selected to ensure that the connection between the wires and the equipment is tight and reliable, with a large contact area to reduce contact resistance.
Wiring should be carried out according to the wiring diagram provided by the equipment manufacturer to ensure the correctness and consistency of the wiring.
The lead-out wires should be firmly fixed to avoid pulling or extreme bending, which may cause wire breakage or poor contact.
Grounding protection:
Mechanical equipment should be reliably grounded to ensure the safety of the equipment and personal safety.
The grounding resistance should meet national standards to ensure the effectiveness of grounding.
The grounding conductor should be made of high-quality copper busbars or copper wires, and should be firmly and reliably connected to the equipment grounding terminal.
Maintenance:
Regularly check the electrical wiring status of the equipment. If there is looseness, damage or corrosion, it should be repaired or replaced in time.
Keep the electrical wiring of the equipment clean, and take care to prevent moisture, dust, etc. from entering the wiring terminals to improve the reliability of the wiring.
Record the specific content and date of each maintenance to facilitate subsequent repairs and tracing.
