Definitions

  • the problem to be solved by the present invention is to provide a tap selector for an on-load tap changer that can reduce the adjustment process of the tap selector.
  • the tap selector of the on-load tap changer of the embodiment has a holding member, a case, a shaft, a roller, and a bottom plate.
  • a holding member holds the movable contact.
  • a case is attached to the holding member.
  • a shaft is attached to the case.
  • the roller is rotatable around said shaft.
  • the bottom plate has a guide portion that guides the roller.
  • the main switching device 20 includes a main fixed unit 21 (fixed portion) and a main movable unit 22 (movable portion) movable with respect to the main fixed unit 21 .
  • the main fixing units 21 are provided in the same number as the collector rings 18 (for example, six in this embodiment).
  • the number of main fixing units 21 corresponding to the three phases of U phase, V phase and W phase (for example, two for each phase in this embodiment, total six) is provided.
  • a plurality of main fixing units 21 are fixed to the main strut 13 at substantially the same intervals in the vertical direction.
  • the movable plate 60 extends in the radial direction of the current collection ring 18 so as to straddle the current collection ring 18 and the fixed plate 40 .
  • the inner portion of the movable plate 60 overlaps the current collection ring 18 when viewed from above and below.
  • the outer portion of the movable plate 60 overlaps the fixed plate 40 when viewed from above and below.
  • a pair of holding members 90 are provided with the main movable unit 22 interposed therebetween.
  • a pair of holding members 90 are arranged on both sides of the main movable unit 22 in the circumferential direction of the collector ring 18 .
  • the main movable unit 22 is vertically movable by being held by a pair of holding members 90 .
  • FIG. 5 is a perspective view showing part of the tap selector 2 of the embodiment.
  • the bottom plate 11 has guide grooves 110 that guide the moving mechanism 100 .
  • the guide groove 110 is formed in an annular shape when viewed from above.
  • the guide groove 110 has an annular shape concentric with the central axis C of the main switch 20 (the central axis C of the column 19).
  • the moving mechanism 100 can move in the direction along the guide groove 110 (the arrow V3 direction in FIG. 5) via the holding member 90 .
  • the direction of arrow V3 in FIG. 5 is the same as the direction of arrow V1 in FIG.
  • the direction along the central axis C of the main switch 20 will be referred to as the "axial direction of the main switch 20"
  • the direction orthogonal to the axial direction of the main switch 20 will be referred to as the "radial direction of the main switch 20”
  • the direction along the central axis C The peripheral direction is defined as "the peripheral direction of the main switch 20”.
  • the axial direction of the main switch 20 is a direction (vertical direction) perpendicular to the horizontal direction.
  • the case 101 has a female threaded portion 124 into which a bolt 123 can be screwed.
  • the holding member 90 has a bolt hole 91 through which the bolt 123 can be inserted. According to this configuration, the case 101 can be attached to the holding member 90 by inserting the bolt 123 into the bolt hole 91 of the holding member 90 and screwing it into the female threaded portion 124 of the case 101 . Therefore, no special fixing members or special jigs are required. Therefore, the number of assembly man-hours can be reduced.
  • FIG. 13 is a cross-sectional perspective view of a movable contact moving mechanism 200 of a comparative example.
  • the movable contact moving mechanism 200 of the comparative example includes a sphere 202 built in a case 201 .
  • the case 201 of the comparative example is provided with a set screw 205 for size adjustment.
  • the bottom plate 209 of the comparative example has guide grooves 210 that guide the spheres 202 .
  • Guide groove 210 is formed in an annular shape when viewed from above.
  • the moving mechanism 200 can move in the direction along the guide groove 210 via the holding member 90 .
  • FIG. 14 is a side view of the connecting wire 206 of the movable contact moving mechanism 200 of the comparative example.
  • the movable contact moving mechanism 200 of the comparative example has a connection line 206 for obtaining a potential.
  • One end of the connection line 206 is connected to the upper portion of the case 201 .
  • the other end of the connection line 206 is arranged near the upper surface of the bottom plate 209 .
  • installation of the connection line 206 requires material cost. Therefore, it is required to reduce the material cost.
  • the roller 103 is rotatable around the shaft 102, so that the contact state of the roller 103 with the guide portions 113 and 114 is maintained constant. Therefore, it is not necessary to adjust the contact state of the roller 103 .
  • the roller 103 does not come off the guide groove 110, the quality is stable.
  • the movement of the moving mechanism 100 does not slow down. Therefore, it is possible to reduce the adjustment process of the tap selector 2, reduce the number of assembly man-hours, and improve the quality.
  • the case 101, the rollers 103 and the bottom plate 11 are made of metal.
  • a pair of rollers are provided facing each other in the axial direction of the shaft.
  • the tap selector includes a biasing member provided between a pair of rollers.
  • the biasing member biases the pair of rollers toward the guide.
  • the configuration of the rollers is not limited to this.
  • a pair of rollers may not be provided.
  • the tap selector may not have a biasing member.
  • only one roller may be provided.
  • the rollers may contact the guides under the action of gravity.
  • the number of rollers installed and the manner of contact with the guide portion can be changed according to the required specifications.
