Long running busway is regularly serviced at least several times a year

The bus duct is spliced together, all of which are fixed by screws, and there is a phenomenon of thermal expansion and cold contraction during operation, so it must need maintenance.

There are generally two reasons for bus failure: 1There are quality problems in the bus bar itself2Improper use, including water ingress and unscheduled maintenance.

If there is a quality problem, then it may be maintained and inspected in two or three years, in addition, there is no problem with the new bus for more than five or six years, that is to say, there is no problem with maintenance for more than five or six years. As for how often it is tested, if there is no overload operation or harsh environment, it is enough to inspect and maintain it every two or three years. In many cases, the general situation can be known through preliminary testing.

In addition, try to reserve more accessories with the manufacturer. As for other details and those you don't understand, you can consult me v 三玖厖一55202.

It needs to be repaired every year, check the insulation performance, the tightness of the bolts at the connector, and it is best to check the temperature at the connector and the elbow regularly.

The national standard requires that the temperature of the shell cannot exceed 50 degrees Celsius at room temperature, and it is best to raise this requirement a little, if the temperature exceeds 40 degrees from room temperature, it is necessary to find out the reason.

When the bus duct is in long-term operation, it should be regularly overhauled at least once a year.

Modern high-rise buildings and large workshops require huge amounts of electrical energy, and in the face of the hundreds or thousands of amperes of strong current required for this huge load, safe and reliable conduction equipment is selected, and the bus system is a good choice. The busway system is a power distribution device that efficiently transmits current, especially for the economical and rational wiring of taller and taller buildings and large-scale factories.

Many busways are maintenance-free for life, see what brand you use.

1. Schneider busway is maintenance-free for life.

2. LG (LS) bus duct is maintenance-free for life.

a In the distribution system, when one bus fails or is repaired, the other bus can continue to operate.

a.Single bus segmented wiring;

b.Single bus wiring;

c.Inner bridge wiring;

d.Outer bridge wiring.

Sectionalized configuration is the electrical main wiring that uses a disconnector or circuit breaker to segment a single bus. When the number of incoming and outgoing circuits is large, the single bus wiring has been unable to meet the requirements of power supply reliability, in order to improve the reliability of power supply, the impact caused by fault and maintenance is limited to a certain range, and the single bus can be segmented by using disconnector or circuit breaker.

In the process of designing the grandson, the relevant staff need to ensure the reliability of the line, and the disconnector can be segmented, and the bus can restore the power supply after the disconnector is opened. After the line runs for a period of time, there will be a fault problem, so the power company should arrange maintenance personnel to regularly inspect the line to check whether the equipment has hidden faults. Lack of Kai to sell.

When optimizing the wiring method, it is necessary to ensure flexibility and convenience, and also have a long-term vision to ensure the expandability of the line, shorten the time of maintenance and circuit power failure, so as to reduce the impact of the fault and economic losses.
