The structure of a 110 kV substation is mainly composed of several core components, including transformers, switching equipment, protection devices, measuring instruments, and auxiliary equipment. Transformers are the key devices used to convert high-voltage electrical energy into lower voltage levels suitable for end users. Switching equipment is responsible for controlling and protecting circuits, ensuring the safe and stable operation of the power supply system. Protection devices monitor system conditions, promptly identify faults, and disconnect faulty equipment to prevent the escalation of accidents.

Below is a summary of the main equipment used in a 110 kV substation and their functions:

Through the above analysis of the structure and equipment, it can be seen that 110 kV substations play a vital role in daily operations, ensuring the efficient and reliable operation of the entire power supply system.
