1) Closing the bus duct can reduce the grounding fault, prevent the short circuit between the phases, and fundamentally eliminate the grounding fault caused by external moisture, dust and foreign objects, and improve the continuity of generator operation.
2) Eliminate the heating of the surrounding steel structure. The exposed high-current bus bar causes eddy current and hysteresis loss of the surrounding steel structure and steel bars under electromagnetic induction, and the heating temperature is high, the loss is large, and the strength of the structure will occur. Closing the busbar and selecting shell shielding can fundamentally deal with the induction heating of the steel structure.
3) Greatly reduce the electrodynamic force of phase-to-phase short circuit. When an interphase short circuit occurs outside the area, and a large short circuit current flows through the busbar, the short-circuit electrical force of the interphase conductor is greatly reduced due to the shielding effect of the shell.
4) After the bus is closed, the use of micro positive pressure equipment can prevent the condensation of the insulator, improve the safety and reliability of operation, and create conditions for the use of forced ventilation cooling method for the busbar.
5) The operation and maintenance workload of the busbar is small, and the structure is simple.

Wiener bus adapter features:
Functional aspects
The bus bar is made of copper or aluminum, which has high current density, small resistance and small skin effect, and does not need to be used for capacity reduction. The small voltage drop also means that the energy loss is small, which ultimately saves the user's capital. As far as the cable is concerned, because the cable core is a multi-strand thin copper wire, its root surface ...
