System and rated voltage
The system voltage is 12kV, and the rated working voltage is 10kV. These are the basic voltage parameters for the switchgear to operate in the power system, which determine its applicable voltage level range, ensure matching with the 10kV transformer, and ensure the stability and safety of power transmission.
Rated current range
The rated current has multiple specifications from 630A to 4000A to meet the needs of transformers of different capacities and loads. The current carrying capacity is a key indicator to measure whether the switchgear can stably transmit electric energy. When the current is too large, a switchgear with a suitable current level must be selected to avoid overload.
Rated frequency
The rated frequency is 50Hz/60Hz, which adapts to the power grid frequency in different regions. The stability of the frequency is crucial to the normal operation of the transformer and switchgear. Frequency deviation may cause abnormal operation of the equipment, affecting the stability of the power system and the life of the equipment.
Core features and advantages
Advantages of the removable structure
The removable structure facilitates the installation, maintenance, and replacement of equipment and improves the flexibility and maintainability of the switch cabinet. When the internal components of the switch cabinet need to be repaired or replaced, the components can be quickly removed to reduce power outage time and improve power supply reliability.
Flexible operation and maintenance
The design of the switch cabinet focuses on the convenience and flexibility of operation. Operators can easily perform opening and closing operations, parameter settings, etc. At the same time, it is equipped with a complete indication and alarm system to facilitate real-time monitoring of the equipment operation status and timely detection and handling of abnormal situations.
Importance of the live-protection interlocking
The five-protection interlocking is an important safety feature of the switch cabinet. It prevents safety accidents caused by misoperation, such as preventing the opening and closing of disconnecting switches with load, preventing accidental entry into live intervals, etc. Through mechanical and electrical interlocking devices, it ensures the correctness and safety of operation and ensures the stable operation of the power system.
