摘要:
An electromagnetic position indicator to continuously indicate the position of a linearly movable mobile, such as a nuclear reactor control rod, operatively connected to magnetic core means which vary the inductive coupling between primary and secondary windings. One of the windings, preferably the secondary winding comprises pairs of oppositely connected coils spaced apart in the direction of movement of the core means to improve the measurement precision. Analog or digital means may be provided to process the output signal.
摘要:
A high-voltage disconnecting switch for establishing an electrical connection between two vertically spaced contacts by means of a movable contact capable of being moved in a vertical translation by a drive mechanism which comprises a threaded drive rod cooperating with an internally threaded element wherein the fixed moving contacts as well as the drive rod are axially arranged in a supporting structure comprising a plurality of superimposed sections defined by transverse plates, the plates of the upper section supporting the fixed contacts and providing guide means for the moving contact.
摘要:
Linear induction motor comprising a magnetic field structure bearing two spaced coils supplied with currents out of phase by an angle of 2 pi /3 and dividing the air gap face into three equal pole faces to produce a balanced travelling magnetic field.
