Bus, transformer, generator set unit wiring. It has the characteristics of simple wiring, less switchgear, easy operation, suitable for expansion, and because there is no generator outlet voltage bus, the short-circuit current of the low-voltage side of the generator and the main transformer is reduced.
The double bus wiring of the bus machine has the advantages of reliable power supply, convenient maintenance, sensitive scheduling or convenient expansion. However, there are many equipment (especially barrier switches) used in this kind of wiring, and the power distribution device is messy, and the economy is poor; As an operating electrical appliance in operation, the barrier switch is prone to misoperation and is inconvenient for completing automation; Especially when the bus system fails, it is necessary to cut off more power supplies and lines in a short time, which is not allowed for particularly important large power plants and substations. Single bus wiring. Single-bus wiring has the advantages of simple and clear, less equipment, small investment, convenient operation and conducive to expansion, but it is less reliable and sensitive.
When the bus or bus barrier switch fails or is overhauled, it is necessary to disconnect the entire power supply of the bus. Single, double bus or bus segmentation plus bypass. Its power supply is reliable, sensitive and convenient, but the investment has increased, and the economy is slightly poor. In particular, when the circuit is carried with a bypass circuit breaker, the operation is messy, which increases the opportunity for misoperation. At the same time, due to the installation of bypass circuit breakers, the corresponding protection and automation system is messy.
