Title: Improvements in electric protective apparatus
IPC: H02H9/02
Filed: 1953-02-26
Abstract: 731,350. Protective arrangements. TAYLOR, A. M. Feb. 26, 1953, No. 28350/51. Class 38 (5). A protective arrangement having means for rapidly blowing a fuse in a heavy-current circuit, and which may be used in conjunction with the stabilizer of Specification 661,859, [Group XXXV], comprises a fuse 5 connected as a short-circuit across the secondary 8 of a transformer 7, the primary 6 of which is transformer-, or directly, connected to the protected line. In series with the primary 6 is a further primary 10 (either directly or transformer connected) of a saturable transformer 11, the secondary 12 of which supplies a tertiary winding 9 of transformer 7, the winding 9 opposing the primary 6. The transformer 11 is saturable at normal full-load, so that up to that point no secondary current flows through the fuse 5, but above that current, the winding 9 no longer balances the winding 6, current from which ruptures the fuse 5 which can be of low rating. A capacitor 18 eliminates the restrike-transient and is itself cut out by a fuse 19. The above arrangement operates to introduce a high current-limiting impedance in the circuit, but in Fig. 4 a complete break in the circuit can be effected by a further fuse 22 supplied from a transformer 20, 21 energized when fuse 5 blows. In a further form (Fig. 5, not shown), a set of transformers 7, 11 operate to blow a fuse such as 22 directly after the blowing of fuse 5, an additional fuse in the circuit of secondary 8 then serving to break the circuit through the latter. Spare fuses may be arranged to be inserted across the secondary 8 of Fig. 3 by means of electromagnetic relays energized in parallel with the fuse 5, so that when the latter blows, the circuit is automatically restored with a time-delay (Fig. 6, not shown). The winding 8 may be subdivided into a number of windings each supplying a fuse in series with an inductance, or a number of fuses in parallel, each in series with an inductance, the mid-points of the secondaries and the connections between the respective fuses and inductances being earthed (Fig. 7, not shown).
