T h e principal construction i s explained with the Installation Drawing (Appendix N 1018e): T h e t a p changer head (21), arranged o n the t r a n s f o r m e r c o v e r , contains a reduction g e a r and a spring-operated energy accumula- t o r f o r the diverter s w i t c h , a s t e p - b y - s t e p g e a r f o r the tap s e - l e c t o r , and the fixing parts o f the exiricable diverter switch unit. T h e t a p changer h e a d offers connecting facilities for a n outside p i p e w h i c h l e a d s t o t h e o i l c o n s e r v a t o r via the protective r e l a y R S 1 0 0 0 ( 2 6 ) o r , a s a drain pipe ( 2 7 ) , c a n b e u s e d f o r draining t h e o i l t a n k. It contains the vent p i p e s (28) from which residual gas caused when filling oil into the transformer can escape from under the tap changer h e a d. T h e suction pipe, however, i s only furnished when o r d e r e d. The mechanical drive i s effected from outside the tap changer head via the driving shaft end (25). One tap change requires 33 revolutions of the driving shaft. The diverter switch oil tank (31) located under the tap changer head separates the diverter switch and its oil from the transformer oil. T h e diverter switch unit (51), which can b e exiracted for revision purposes, i s i n the di- verter switch oil tank. With the standard version of t h e diverter switch oil tank this separation i s leak-proof for the oil within the t a n k , With the p r e s s u r e - t i g h t version a m a x i m u m p r e s s u r e d e v i a - tion o f 0. 3 a t m i s p e r m i s s i b l e. T h e diverter switch oil tank i s sealed b y the flanged oil tank bottom (32). T h e interior parts o f the tap selector comprise the tap selector suspension ‘tube and the fixed take-off rings mounted o n the t u b e , T h e rings a r e connected with the terminals (45) b y the movable tap s e l e c t o r contact b r i d g e s. T h e step-by-step operation o f the contact bridges i s performed b y the s t e p - b y - s t e p gear mounted i n the tap changer head (21). The terminals connected with the corresponding t a p s o f the regulating winding are arranged o n the vertical paper laminate shafts o f the tap selector. T h e connecting l e a d s ( 4 8 ) arranged outside the tap s e l e c t o r connect the diverter switch with these terminals, T h e output terminals o f the tap chan- g e r (with D III 200/400: output a t the neutral point) a r e arranged o n the take-off ring (36) i n a w y e pattern.

T h e following instructions should b e followed: Sealings o f the tap changer head and the protective relay RS 1000 should b e oil-proof. T h e housing o f the motor drive should be water-tight. T h e electric heating i n the housing o f the motor drive should work irreproachably (the thermostat i s set t o 1 0 C ) i n order t o avoid condensation o f w a t e r. T h e outlook o f the control instruments installed i n the motor drive (contactors e t c. ) should b e observed.
