Now, power consumption is increasing. In order to meet the power demand, bus duct equipment can ensure the transmission of large current and safe use. Do you know what this product needs to be overhauled regularly? Next, Jinan cable tray manufacturer will explain to you.
Before the maintenance of the bus passage, the power distribution cabinet must be cut off first, and the sign "No switching on, no switching on" must be hung, and a special person must be assigned for monitoring. Before maintenance, check and discharge. After using the grounding rod, the interphase circuit and reliable grounding can be carried out.
Regularly check the voltage of each incoming terminal of the bus duct, and confirm that the bus duct has completely cut off the power supply. Frequently wipe the dust on the bus duct with a soft brush, vacuum cleaner or cotton. The total load current of the bus duct shall not exceed the main bus current or design current.
Check the temperature of the operation site. Check whether the connecting bolts are loose within 3 months after the equipment is installed and used. After 1 year, check the connection bolts on multiple sides, and check the rest every 3 years.
Pay special attention to the clamping torque and surface cleanliness of the joint. If the structure is loose or polluted, the resistance will increase and overheat. Even uneven joint surfaces may be arced.
If the bus duct operates for a long time, it shall be checked regularly at least every year to ensure safety, and then check that the total load current does not exceed the design current and the rated current of the main bus duct.
Before maintaining the bus duct, check whether the bus duct system is powered off! Cut off the power supply of all bus ducts!
In addition, the instrument is used to measure whether there is voltage in the conductor. After confirming that the bus duct system is not charged, routine maintenance can be carried out to prevent high voltage from causing injury to operators.
Although the large current carried by the bus duct can meet the power demand of people, there are still many problems that need attention in the use process. During use, regular maintenance and inspection shall be carried out to ensure the safety of bus duct current transmission.
