Application
Medium Voltage (MV) Switchgear is designed for controlling, protecting, and isolating electrical equipment in applications that include power distribution for utilities, industrial plants, commercial buildings, and renewable energy installations.
Functions and Applications:
Power Distribution: MV switchgear distributes power across different levels of the electrical grid and within industrial facilities.
Protection and Control: It isolates faults, preventing cascading failures, and ensures safety for maintenance and operation.
Industrial and Utility Use: MV switchgear is widely used in substations, industrial plants, commercial buildings, data centers, and renewable energy plants.
Benefits and Advantages:
Safety and Reliability: MV switchgear provides robust protection, preventing equipment damage and personnel injury from electrical faults.
Flexibility: Available in various configurations and forms, MV switchgear can adapt to different applications.
Space Efficiency: Compact designs, particularly in GIS and RMU setups, allow installation in constrained spaces.
Specifications
Rated Voltage: Commonly from 3.6 kV to 36 kV, matching the distribution level.
Rated Current: Typically between 630 A and 4000 A, depending on the specific application.
Short-Circuit Current Rating: Indicates the maximum fault current the switchgear can handle for a specified time, usually 25-40 kA for 1-3 seconds.
IP Protection Rating: Higher IP ratings provide protection against dust, water, and accidental contact, commonly ranging from IP2X to IP4X or IP5X for MV switchgear.
MV switchgear must comply with international standards such as IEC 62271-200 for metal-enclosed switchgear and GB3906 in China, ensuring safety, reliability, and operational efficiency.
Key Components:
Circuit Breakers: The primary protective devices in switchgear, circuit breakers disconnect the circuit in the event of a fault. Common types are vacuum circuit breakers (VCB), SF6 circuit breakers, and oil or gas circuit breakers.
Busbars: Metal strips or bars that distribute electrical power from incoming circuits to outgoing circuits.
Current and Voltage Transformers: Measure electrical parameters and relay the information to protective relays.
Protective Relays: Devices that detect abnormal conditions (like overcurrent, undervoltage) and trigger the circuit breaker.
Switches and Fuses: Additional protection and isolation components, often used in simpler switchgear setups.
