What is a busbar?

Distribution power supply unit main power supply line (copper, aluminum, called busbar), the branch lines (branch rows) from the busbar on the lead down.

What is the difference between busbar and busbar?

1 busbar refers to the switchgear in the bus, and switchgear and transformers connected to the conductor;

2 single busbar refers to the configuration of the switchgear wiring;

3 Currently, the vast majority of switchgear is a single busbar, that is, the top of the cabinet is only a set of three-phase busbar, and only a very small number of switchgear can be done double busbar, that is, the top of the cabinet has two sets of three-phase busbar;

3 Single bus segmentation, that is, a power supply bus is divided into two segments, by two power supply two segments of the bus, two segments of the bus between a sectional circuit breaker connection. This wiring can improve supply reliability. When a power failure, you can close the sectional circuit breaker, jumping off a faulty power supply, you can still use another normal power supply two buses;

4 single bus segmentation does not lie in a few switchgear, it can be two switchgear, can be dozens of switchgear, as long as the bus above the above principles of segmentation, it is a single bus segmentation.

What is an electrical busbar?

Busbar generally refers to the copper rows in the distribution cabinet, is the power busbar in the electrical cabinet, with large current flow capacity.

What is the copper busbar, what is the role

It is the busbar row, generally 3 items of 5-wire system, as the main line of transmission of electricity. There is the main line in the workshop, there is also the cabinet bus, the cabinet is recommended to choose Granary, this we use more.

What is a grounded busbar?

It is the connection conductor between the grounding body of the building, currently there are flat iron, flat steel, nano-materials conductor, copper-clad steel and so on. The grounding busbar is used as the main trunk line connecting the grounding pole to form the grounding network. It is mainly to introduce the lightning current into the ground through the grounding pole. It is also the backbone of the grounding network.

The grounding busbar is also the connection of other electrical equipment grounding, play the role of other electrical equipment or may be charged equipment leakage current into the ground.

What is the copper row

Copper row, also known as copper busbar or copper busbar, is made of copper, rectangular or chamfered (rounded) rectangular cross-section of the long conductor (now generally used rounded copper row, to avoid the tip of the discharge), the role of the circuit to transport the current and connecting the role of the electrical equipment.

Copper row in the electrical equipment, especially complete sets of power distribution equipment has been widely used; generally in the distribution cabinet in the U, V, W-phase busbar and PE busbar are used in copper row; copper row in the use of the general labeled with the phase color letter mark or painted with the phase color paint, the U-phase copper row coated with "yellow" color, V-phase copper row coated with a "green" color, "green" color, "green" color, "green" color, "green" color, "green" color, "green" color, "green" color, "green" color. U-phase copper row coated with "yellow" color, V-phase copper row coated with "green" color, W-phase copper row coated with "red" color, PE busbar copper row coated with "yellow and green" dual-color.

"Primary bus" in the "one" is what it means

A bus, also known as the main bus. It is a busbar used for high current transmission in electrical equipment.

The primary is relative to the secondary, the secondary is used for primary control, protection, measurement, metering and so on.

It can be said that: the primary is the purpose of the existence of electrical equipment, the secondary is the auxiliary function of electrical equipment.
