Bus load forecasting method and characteristics - Wiener
Bus load guessing is a kind of power system load guessing, and the bus system load can be defined as the sum of the terminal load supplied by the main transformer of the substation to a relatively small power supply area, which is the refinement of the system load. Bus load guessing generally only carries out short-term load guessing, and the result is ...

Rectangular busbar, trough busbar, and tubular busbar analysis
The rectangular bus has good heat dissipation performance and is easy to fix and connect. But its skin effect is quite large. In order to reduce the skin effect, the cross-sectional area of a single busbar should not exceed 1250 square millimeters. When the working current exceeds the promised current of a single bus, 2 to 4 rectangular buses can be used. Rectangular conductor a ...

Detailed explanation of Wiener DC bus
1. Three-phase AC power supply inlet
The power input of each inverter is connected in parallel on the same AC bus, and the power phase of the input end of each inverter is ensured. The circuit breaker QF is the incoming line protection device for each inverter. LR is an incoming reactor, when multiple inverters are operating in the same environment.

Lighting power busway service life - Wienal
The system consists of a current box, a bus body, a branch plug and device accessories.
When the heat dissipation of conductive copper strip has been effectively improved, the contact between the copper strip and the inner wall of the tube is reduced, and the insulation resistance and anti-aging ability of the tube body are strengthened, so as to prolong the service life of the pipe body. The life of the tube far exceeds ...

220V DC Hazard of Bus System – Wiener
The grounding of the DC system should include two situations: the one-point grounding of the DC system and the two-point grounding of the DC system.
In the DC system, the positive and negative poles of the DC are insulated from the ground, and when the ground of one pole is generated, there is no grounding current due to the fact that there is no grounding current.
