NSP-2010 Over-voltage Electric Fast Protection Device

Mode: NSP-2010
Because resonant system’s over-current protection is not really effective when discharging periods, so its necessary for us to equip fast protection device.
Rated voltage: 0.38kV                                                  Transient state max. current: 2.5kA
Response time:< 100μs                                                Restrain protection time: >200ms (Adjustable)
Sensitivity: 10% ~ 100% adjustable.                        Working time: 15min on, other working time please contact with sales.
Fast breaker can get down transformer’s primary voltage within 1 millisecond to 50% of previous value until breaker trip, its advantage are:
Extinguish arc, which is cause by breakdown, restrain over-voltage, protection test object and system itself, and extent system’s working life;
When test object breakdown, fast controllable silicon is triggered, which get down transformer’s voltage in 10ms, and absorb magnetic field energy inside of transformer, get down over-voltage and extinguish arc on the test object;
The communication between strong electricity and weak electricity is done by optical fiber, which has excellent performance on anti-interference.
The device is consist of detection circuit, logical judgement amplifying circuit, strong trigger circuit, high speed thyristor and reactor self-control, indicating, and preset protection circuit, five parts. Each circuit is connected with optical fiber.
Install inside the console.
