Definitions

  • the tap selectors for switches used in the voltage regulation of loaded transformers usually comprise cylindrical casings formed of insulating rods disposed peripherally United StatesPatent tap.
  • the regulating taps are gen- In the I ice In transformers, with regulation when on load, the switching from one tap to the next is made without interrupting the .load, owing to a switch which momentarily shunts the contact taps.
  • FIG. 1 shows a simple case of the phase regulation of a transformer when a selecting switch 1 is in position 2.
  • the choic'eiof a tap is made on the selector S by the cascade displacement'of brushes B and B
  • brush B erally made on the outside windings in order that the con' 1 nection cabling lie at the same level between the taps is to be applied to transformers of the shell-core type
  • brush B pass successively pass on the fixed contacts of the odd-numberedseries 'c, e, g,;i, k, m and o by joining them successively with a common point S
  • brush B pass successively on the fixed contacts of the even-numbered series d, f, h, j, l and n by joining them successively to a common point S
  • These common points S and S are joined to breaker R.
  • a movable support member ms T carries aplurality of contacts coupled to one terminal of such cases, the regulating taps providedon the windings T are located on the upper portionthereof.
  • connection To reach the fixed contact of the selectors, the connection must travel a long and sinuous path and this arrangement is detrimental tothe good insulation of the conductlre windings while a fixed support member fs carries a corresponding plurality of contacts divided into two groups which are coupled via adequate impedances iprespectively to two successive taps of the windings by means of S and S The. moving support member is moved with respect to the stationary [support member and pairs of contacts are sequentially connected so that the tap may tors and further requires great precautions in making the connections.
  • One object ,of the invention is to provide a selector which, when used with shell-core transformers, eliminates the above noted objections.
  • the 'invention' is. characterized that the'contactai two groups located at each end of an insulating cylinder and are equally spaced in each group.
  • the effective surwhich are joined to the regulating taps, are distributed in faces of the contacts are located outsidethe cylinder and their connecting lugs to the conductors, joined to the regulating contacts, are located inside the said cylinder.
  • the invention is also characterized in the fact that the insulating cylinder lies horizontally, that is, normal tothe late'ralfwall of the transformer tank-
  • FIG. 1 is a diagram of the regulation of one phase of the invention.

  • Thecommon points S and 8 are formed as rings (there being one ring per layer) and joined to breakerR.

  • Three brushes 8 B B are also dis I posed 120 apart-and secured onto a movable ring iii exteriorly concentric to cylinder 5 and also having a toothed. portion 12. it is possible by means of the three brushes to bring together each of the fixed contacts of one phase with one of the three segments S S S respectively corresponding to the three phases by the rotation of toothed pinion ll.
  • the spacing between two adjacent contacts belonging to two diiierent phases can be the same as that of two consecutive contacts of one phase. It is therefore only necessary, in order to cover the regulating range a second time, to continue the movement in the same direction.
  • the brushes B can move from contacts 0 of one phase to contacts 0 of. the following phase; the same being true of the brushes B which can move from contacts n to contacts b since segments S 3 13, S as well as segments 82A, S S are insulated from one another.
  • FIGS. 3 and 5 An embodiment of such a selector is diagrammatically illustrated in FIGS. 3 and 5. It is made up of an insulating cylinder 5 on which are secured, at theperiphery of one of its ends, the odd-numbered fixed contacts P and at the other the even-numbered fixed contacts pp of the three phases as shown in FI GS. 2 and 3.
