Title: On-load tap changing transformer
Inventor: KOSAKA MASAAKI
IPC: H01F29/04
Filed: 1986-04-24
Abstract: PURPOSE:To inhibit the increase of the ground potential of a tap winding and the interrupting energy of a polarity changer without adding a special member by adjacently arranging a part winding to the tap winding and elevating the ground capacity of the tap winding. CONSTITUTION:A part winding 21 in a plurality of turns separated from a terminal section on the polarity changer 4 side of a voltage-adjusted main winding 11 is rolled together into a tap winding 22 together with a coil conductor for the tap winding 22, and the mixed winding 20 of the tap winding 22 and the part winding 21 is formed. Since potential difference et+alpha between both windings is made remarkably smaller than the induced voltage (e) of the main winding 11, an insulating distance between both windings may be reduced, thus remarkably making coupling capacity Ck between both windings smaller than that C12 between the main winding and the tap winding. Accordingly, potential difference e56, e57 among poles can be minimized largely while the interrupting energy and dielectric strength of the polarity changer 4 can be lowered without using an additional member, such as a shielding plate, an energy absorbing element, etc.

IPC: B01D29/60
Filed: 1982-06-03
Abstract: PURPOSE:To prevent a filtrate from sucking a gaseous body, by providing an upper over-flow hole having large area and a lower over-flow hole having small area to the side wall of a filtering tank, and reducing the lowering of a liquid level in the tank caused by backwashing. CONSTITUTION:A dirty liquid is filtered by a filter body 6 by providing an upper overflow-hole 2 having large area and a lower overflow-hole 1 having small area to the side wall of a filtering tank 4 and pumping up the dirty liquid from a dirty liquid tank 5 to the tank 4 by a pump 7 so as to adjust the liquid level to the lower end of the hole 1. A filtrate is discharged by a constant feed pump 8 through a pipe 11. When the filter body 6 is backwashed, a compressed air is fed from a backwashing pipe 12 to the body 6 through a check valve 9 after stopping the pump 8. By this operation, the dirty liquid increases its volume by the produced air bubbles, and mainly the air flows out of the hole 2 and mainly the liquid flow out of the hole 1, but the amount of flow-out liquid is decreased because of the small area of the hole 1.
