The load connection and grounding connection scheme of
diesel generator sets mainly includes load connection method and grounding connection method.
Load connection method
The load connection method of diesel generator sets mainly depends on the output of the generator and the demand of the load. Normally, the output of a diesel generator set is a three-phase four wire system, consisting of three live wires and one neutral wire. When wiring, it is necessary to consider the balance of three-phase loads. If single-phase electricity needs to be connected, any one of the three live wires can be selected as the live wire, and then a neutral wire can be connected. For large diesel generator sets, the wiring method is similar to that of small generators, and it is also a three-phase four wire system. The specific wiring methods include star connection and delta connection. Star connection is suitable for scenarios that require higher volts and lower currents, while delta connection is suitable for scenarios that require lower volts and higher currents.
Grounding connection scheme
The grounding connection scheme for diesel generator sets includes three methods: protective grounding, working grounding, and protective grounding. Protective grounding is mainly used to provide safety protection and prevent electric shock accidents when the neutral point is not grounded. Working grounding is used to reduce the insulation level and electric shock voltage of electrical equipment to ground, ensuring personal safety. Protective grounding is suitable for generator sets in high-power or harsh environments to prevent the expansion of leakage accidents. The correct grounding connection needs to comply with relevant national standards and specifications to ensure the safety and stability of the electrical system.
The above is an introduction to the load connection and grounding connection schemes of relevant diesel generator sets organized by Huaquan Power for you. Choosing the correct power supply scheme for diesel generator sets and conducting timely and correct electrical design is an important aspect related to the rationality, reliability, safety, and other aspects of the entire power supply system design.
