The transformer substation is a place for converting voltage and current, receiving electric energy and distributing electric energy in an electric power system. The substations in the power plant are step-up substations, which are used to boost up the electrical energy generated by the generator and feed it into the high-voltage network. The primary equipment refers to equipment for directly producing, conveying, distributing and using electric energy, and mainly comprises a transformer, a high-voltage circuit breaker, an isolating switch, a mutual inductor (a current mutual inductor and a voltage mutual inductor), a bus, a lightning arrester, a lightning rod, a capacitor, a reactor and the like. The secondary equipment of the secondary equipment substation is equipment for measuring, monitoring, controlling and protecting the operation conditions of primary equipment and a system, and mainly comprises a relay protection device, an automatic device, a measurement and control device, a metering device, an automatic system and direct current equipment for providing power for the secondary equipment.
The lightning protection device is the sum of a lightning receptor, a down conductor, a grounding device, a Surge Protector (SPD) and other connecting conductors. Lightning protection devices for buildings are generally classified into two categories; an external lightning protection device and an internal lightning protection device. The external lightning protection device consists of a lightning receptor, a down conductor and a grounding device, namely the traditional lightning protection device. The internal lightning protection device is mainly used for reducing lightning current and electromagnetic effect inside a building, for example, measures such as electromagnetic shielding, equipotential connection and Surge Protection Device (SPD) installation are adopted to prevent possible damage caused by lightning electromagnetic pulse. The grounding device is an important component of the lightning protection device, and the grounding device releases lightning current to the ground to limit the voltage of the lightning protection device to the ground from being too high. Except the independent lightning rod, the lightning protection grounding device can be shared with other grounding devices on the premise that the grounding resistance meets the requirement. However, the lightning protection device of the existing transformer substation has poor lightning protection effect and is inconvenient to use.
