Alstom SKD11BF8003BCH Synchronous Relay Product Features
Belonging to the Alstom SKD series synchronous relay, it is used to prevent non compliant power supply from running in parallel.
Mainly used in the automatic reclosing sequence of contact lines, in conjunction with automatic reclosing relays.
The relay contacts are connected in series in the circuit breaker closing circuit to ensure that the phase, voltage, and frequency differences are within the preset range before closing.
Adopting static design, low load operation, high precision and stable reliability.
Capable of withstanding transients and surges, able to pass 5kV impulse voltage testing and adapt to harsh environments in power systems.
The frequency is set to 50Hz, suitable for standard power frequency systems.
The voltage lock setting accuracy is ± 5%, ensuring accurate voltage difference detection.
The action time when the timer is disconnected is about 200 milliseconds, and the response is fast.
Under rated voltage, each power supply has a burden of only 2.5VA and low power consumption.
Commonly used for safety checks of manual synchronous operation of generators to prevent asynchronous closing.
