Development and introduction of manufacture of WWER-1000 linear stepping drive

  • 1. Skoda, Plzen (Czechoslovakia). Zavod Energeticke Strojirenstvi

Description

A new position indicator was developed for the linear stepping motor driving the control elements of WWER-1000 reactors. The linear motor is pawl type, with a step of 20 mm. The new position indicator involves a sensor which is located in the rector pressure vessel and is formed by eight single-winding coils for operating temperatures up to 340 degC. The coils are accommodated in a pressure tube 18/13 mm in diameter, which is rated for a full external test overpressure of 25 MPa and, in case of failure, additionally secured by a bushing rated for this overpressure as well. Signals from the sensor are transmitted through six wires to two independent position indicators, viz. a main one and a standby one. (Z.M.). 3 figs
