(Summary description)Before the maintenance of the busway, you need to check the busbar system for power failure! Completely block all power supply of the busway! Use a multimeter to measure the presence or absence of voltage of the conductor, and acknowledge that the busbar system is not powered before it can be routinely repaired. Avoid high voltages that cause physical damage to the operator. When the busway is operated for a long time, the temperature rise of the joint is detected once a year, and the temperature rise of the joint should be qualified according to the specification without exceeding 70K (the ambient temperature is 40 degrees). Check whether all the busbar joints and the conductors touch the surface. Avoid the occurrence of heat generation due to the increase in resistance caused by looseness. Check if the insulation material has an aging appearance.

Before the maintenance of the busway, you need to check the busbar system for power failure! Completely block all power supply of the busway! Use a multimeter to measure the presence or absence of voltage of the conductor, and acknowledge that the busbar system is not powered before it can be routinely repaired. Avoid high voltages that cause physical damage to the operator.
 
When the busway is operated for a long time, the temperature rise of the joint is detected once a year, and the temperature rise of the joint should be qualified according to the specification without exceeding 70K (the ambient temperature is 40 degrees). Check whether all the busbar joints and the conductors touch the surface. Avoid the occurrence of heat generation due to the increase in resistance caused by looseness. Check whether the insulating material has an aging appearance, and whether the conductive part has a melting deformation appearance. If it is found that there is a phase indirect, insulation breakdown phenomenon, it should be removed in sections and viewed with a pressure tester to find out the problem, or replace the busway from the head, or carry out insulation coating from the beginning. Check if the socket pin and busbar touch of the busway system are outstanding.
 
During the operation of the busway, it should be uninterrupted to check whether there are leakage, water spray, potential moisture sources around the whole system, whether there are any organisms that pose a threat to the system, and the heat source that affects the temperature rise of the busway system. Check whether there is any foreign matter entering the inside of the busway, check whether the components of the system are defective, rusted, and whether the bracket spring can have appropriate elasticity. Immediately after the problem is found, replace it.
