High Voltage 11kv 12kv AC Metal Clad Switchgear
I. Core Structure and Protection
Metal Shield Design: The cabinet body is made of steel plates and other metal materials and is either fully enclosed or segmented isolated to form a "metal shield" structure. It encloses components such as circuit breakers, disconnectors, busbars, and cable heads, with a protection level typically reaching IP3X or above. This design effectively prevents dust and foreign object intrusion and limits the spread of fault arcs, enhancing safety.
Internal Segmentation: It is divided into independent compartments such as busbar chamber, circuit breaker chamber, cable chamber, and instrument chamber based on functions. These compartments are isolated by metal partitions to reduce interference between different components and the risk of fault propagation.
II. Functions and Compatibility
Core Function: As a key device for 11kV/12kV power distribution systems, it performs power on/off control, line protection (overload, short circuit, etc.), and status monitoring. It can be combined with core components such as vacuum circuit breakers and SF₆ circuit breakers to achieve reliable operation.
Compatible Scenarios: It is mainly used in indoor power distribution sections, such as substations, industrial areas, and high-voltage distribution rooms of large buildings. It is compatible with medium and high-voltage power distribution networks of 10kV level to meet the requirements of power distribution and safety protection.
III. Outstanding Features
High Safety: The metal shield and internal isolation design, combined with "five prevention" interlocks (preventing misoperation, etc.), significantly reduce the risks of electric shock and arc injuries to personnel.
High Reliability: The structure is sturdy, adaptable to complex indoor environments, with stable electrical performance, and meets the long-term operation requirements of medium and high-voltage power distribution systems.
This equipment features a metal enclosed structure as the core protection, is compatible with 11kV/12kV AC systems, and is a key device in medium and high-voltage indoor power distribution that balances safety and reliability.
