Title: A three-phase electric power or energy measuring instrument
IPC: G01R11/36
Filed: 1965-12-31
Abstract: 1,072,018. Electric meters. SIEMENS A. G. Dec. 31, 1965 [Dec. 31, 1964], No.55475/65. Heading G1Q. In a three-phase induction meter whose current magnets are unenergized idle torques are set up by interaction of the voltage magnet fluxes, and should one of the voltage connections fail these torques become unbalanced and drive the rotor. To avoid such idle torque errors, the invention proposes a twin disc rotor with two drive systems acting 180‹ apart on one disc and one, at 90‹ to the other two, on the other disc: by diverting voltage flux from the drive system or systems of one disc to act as compensating flux on the other disc it is ensured that the idle torques remain balanced even if the voltage of one phase is disconnected. Figs. 1 and 2 show the voltage magnets of phases I and III acting on the lower disc and provided with magnetic extensions 1 and 3 which terminate at points 10 and 30 adjacent the voltage magnet of phase II, which acts on the upper disc. Under no-load (i.e. no current magnet energization) conditions, possible idle torques are due to: (a) coupling between the voltage fluxes from phases I and III, acting on the lower disc; (b) couplings between voltage fluxes from each of phases I and III and that from phase II; (c) couplings between the main voltage flux from phase II and the compensating fluxes introduced by the members 1 and 3, acting on the upper disc. With all three phases energized, the fluxes of type (a), (b) and (c) are all balanced and there is no resultant torque. If the voltage of phase II fails, only type (a) fluxes operate and since phases I and III are diagonally opposite there is still no resultant torque. If phase I or phase III fails, (a) is inoperative, (b) provides only the I-II or the III-II coupling and so does (c). Thus by suitably positioning the points 10 and 30 it can be arranged that (b)-type and (c)-type fluxes balance whichever of these phases fail. Instead of attaching the magnetic members 1 and 3 to the voltage magnets of phases 1 and III and terminating them adjacent that of phase II, they may both be attached to the latter and respectively terminate adjacent the former: in this arrangement they need not cross over Fig. 8 (not shown). It is also possible to use a single magnetic member, attached to the voltage magnet of phase II and terminating at a point on the lower disc either Fig. 11 (not shown) diagonally opposite or Fig. 13 (not shown) immediately below the phase II drive system. The magnetic members may be replaced by equivalent coil couplings, e.g. Figs. 9 and 10 (not shown) a supplementary coil on the centre limb of the M-shaped voltage coil of phase II may be connected in a closed circuit with similar coils on one outer limb of the voltage magnets of each of phases I and III.

The final catalyst contains 5-90wt% silica. Specified reactants are: bismuth nitrate, chloride, bromide, sulphate, formate or acetate; ammonium molybdate, alkali molybdates or molybdic acid; and other, meta or pyrophosphoric acid. The colloidal silica is suitably derived from an aqueous silica sol. Auxiliary supports specified are silicon carbide, alumina, aluminasilica and titania. The catalyst may also contain as promoter 0.1- 10wt% of alkaline earth metal, rare earth metals, Gp. VIII metals, Gp. V metals or manganese. The catalyst after drying may contain combined carbonate e.g. in excess of 0.1% carbon dioxide, however this is apparently driven out on calcination.
