When starting a gas - turbine generator, its rotor must first be accelerated by external means to approximately 60% of the rated speed. Only then does the start - up process become self - sustaining, meaning the turbine can generate enough power to continue the process independently. To achieve this initial acceleration, energy can be supplied by various means, with a static frequency converter (SFC) being a common choice.Generator circuit breakers (GCBs) play a crucial role in this process. The

When a fault occurs on the bus bars, the entire power supply is interrupted, and all the non - faulty feeders are disconnected. The majority of bus bar faults are single - phase and often temporary in nature. Bus zone faults can occur due to various factors, such as the failure of support insulators, malfunctions in circuit breakers, or foreign objects accidentally falling across the bus bars. To clear a bus fault, all circuits connected to the faulty section must be opened.The most commonly use

With the accelerated construction of smart cities, the urban distribution network is constantly being upgraded and renovated, and the construction of overhead line undergrounding projects is also progressing steadily. A large number of 10 kV overhead lines are being replaced by underground cables. Considering the current situation such as limited space on some urban roads and a shortage of equipment installation locations, higher requirements are placed on the volume, structure, and performance

With the continuous growth of electricity demand and the increasing complexity of power systems, the operating environment and load that substation equipment faces are becoming more and more intricate. This has led to higher requirements for maintenance work. The primary objective of maintenance work is to ensure that the equipment operates in good condition through inspection, maintenance, and repair, and to prevent and eliminate potential faults that may affect the power supply. Currently, the
