Before maintenance,the busbar trunking system needs to undergo a power outage inspection,completely cutting off all power sources of the busbar trunking,and measuring the voltage of the conductors with a multimeter to confirm that the busbar trunking system is not electrified before routine maintenance can be carried out to prevent serious accidents caused by high voltage that may cause physical injury or even death to operators.During long-term operation of the bus duct,it is necessary to regularly check the temperature rise of the joints once a year,and inspect all connection bolts and conductive contact parts of the bus duct joints for looseness to prevent the increase in resistance caused by looseness from causing heating of the joints.

　　The components of bus duct equipment are used to support the conductors in the bus duct equipment.Installation board is a board used to support various components and is suitable for installation in complete equipment,while installation frame is a type of frame used to support various components and is suitable for installation in complete equipment.We check whether the insulation material has aged and whether the conductive part of the continuous mixer has melted and deformed.If phase to phase grounding or insulation breakdown is found,it should be dismantled in sections and checked in sections with a voltage tester to check whether the plug box pins of the busbar trunking system are in good contact with the busbar.

　　During the operation of the busbar trunking,it is necessary to continuously check whether there are leaks,water sprays,potential sources of moisture around the entire system,whether there are any organisms that pose a threat to the system,and whether there are heat sources that affect the temperature rise of the busbar trunking system.The cone screw mixer should be checked for foreign objects entering the inside of the busbar trunking,whether the components of the busbar trunking system are damaged or corroded,and whether the support springs have appropriate elasticity.If any problems are found,they should be replaced immediately.The casing is a component that protects the busbar trunking equipment from certain external factors and prevents direct access to the equipment in all directions.

　　The low voltage drop of bus ducts is achieved by using high-quality conductive materials and arranging them appropriately,which have lower impedance values and voltage drops.High short-circuit strength refers to the use of epoxy resin insulation systems between busbar conductors and external applications,which have mechanical impact resistance and high heat resistance to high short-circuit strength.The aluminum sheath covering the upper and lower parts of the molded shell can prevent damage during handling,and the quick connection method between sections does not require the use of special tools.It can be confirmed with instructions that the connection has been safely completed,and maintenance is free under normal operating conditions.
