OWK-2 Oil-Water Alarm is a detector for monitoring whether the hydrogen cooled generator leaks oil. It composed of shell, float, permanent magnet and magnetic switch, and is equipped with waterproof and explosion-proof travel switch. The structure is fully sealed, made of stainless steel, aluminum and other magnetic resistant materials, which assures the detector to have excellent explosion-proof. It is suitable for monitoring oil leakage of hydrogen cooled generator, liquid level of condensate in condenser, liquid level of boiler steam drum, etc.
When the magnetic contact moves to point A parallel to the magnetic memory contact, the magnetic recording contact will act by the magnetic coupling effect. After the action, the magnetic recording contact will remain in the magnetic memory action holding state after the magnetic contact leaves the magnetic recording contact. Only when the magnetic contact moves back, the magnetic coupling passes through the action point, the magnetic recording contact can reach the original state. Even if the magnetic contact leaves, it will remain in this state and remain unchanged. Therefore, when the magnetic contact and the magnetic contact move back and forth relative to each other, the dynamic on-off signal of the contact can be sent out.
