Definitions

  • the invention relates to the field of gas-insulated switchgears (GIS). More particularly, the invention relates to a GIS having a disconnector-earthing switch (DES) which causes less dielectric field stress when disconnecting and earthing the electrical conductor in the GIS.
  • GIS gas-insulated switchgears
  • DES disconnector-earthing switch
  • Switchgears are provided in high-voltage electrical power systems to enable downstream equipment to be de-energised and isolated so as to permit, for example, repair, maintenance, or installation of a new component.
  • Gas-insulated switchgears are generally preferred to other types of switchgears as they are capable of safely handling large currents and power levels while occupying a substantially smaller volume. Electrical conductors in the GIS are fitted inside tubular compartments filled with insulating gas, typically SF6 gas.
  • the DES typically comprises a disconnector piston arranged to connect to and disconnect from a disconnector contact socket provided in the GIS, and an earthing piston arranged to connect to and disconnect from an earthing contact socket provided in the GIS.
  • the disconnector piston Before the earthing piston of the DES can be connected to the earthing contact socket, the disconnector piston must first be disconnected. For safety reasons, it is imperative that disconnector piston and the earthing piston are never both connected to their electrical contact sockets at the same time. As such, a single actuating mechanism is often employed for operating both pistons of the DES, mechanically configured such that one piston is always disconnected from its electrical contact socket prior to the other being connected to its electrical contact socket.
  • US2010/0089875 A1 discloses such a DES in a three-phase GIS.
  • a DES is shown comprising disconnector piston and an earthing piston mechanically connected to an actuating mechanism.
  • the actuating mechanism comprises a rotary control shaft connected to levers to operate the pistons such that when one is extended to connect to the respective electrical contact socket, the other retracts such that the pistons do not connect to their electrical contact sockets simultaneously.
  • the other is in the process of retracting or extending, which could potentially cause arcing due to the proximity of both pistons to their respective electrical contacts midway during the movement.
  • a DES where the disconnector piston and the earthing piston are also mechanically connected, for operation by a different actuating mechanism.
  • the actuating mechanism comprises a profiled actuation member which is rotated to guide cam followers connected to levers so as to extend and retract the pistons. Furthermore, it is arranged such that when either one of the piston is being extended or retracted, the other piston remains in a retracted position flush with the DES housing. While this reduces dielectric stress significantly, the actuating mechanism is not particularly small, taking up quite a bit of space adjacent the two pistons, which again may cause dielectric stress. Moreover, the actuating mechanism does not have a low part-count.
  • EP 2 824 686 describes a high-voltage electric switching arrangement in a metal casing.
  • US 2014/0116859 describes a 3-way switch for a gas-insulated apparatus.
  • US 2012/0118709 describes a high-voltage assembly.
  • the present invention provides a gas-insulated switchgear (GIS) according to claim 1.
  • GIS gas-insulated switchgear
  • Figure 1 shows a partial cross-section view of a section of a three-phase GIS 100 according to a preferred embodiment of the invention.
  • the DES 10 are positioned adjacent to each other and oriented in the same sense (only two of the three DES 10 being visible due to the position of the cross-section). As the DES 10 are identical, only one will be described.
  • the DES 10 comprises a housing 11 within which a disconnector piston 30 and an earthing piston 40 are provided, arranged for movement along axes which are at an angle of 90° to one another, but lying in the same plane.
  • the disconnector piston 30 is oriented to move along a horizontal axis to extend from and retract into the housing 11, while the earthing piston 40 is oriented to move along a vertical axis to extend from and retract into the housing 11.
  • the housing 11 is provided with cylinders 13, 14, each cylinder 13, 14 having a cylinder opening 13A, 14A through which the piston 30, 40 can extend out of the housing 11.
  • the cylinder openings 13A, 14A are thus openings in the housing 11 from which the pistons 30, 40 can extend.
  • Electrical contact sockets 32, 42 are provided in the GIS 100 for the pistons 30, 40 of the DES 10 to connect to and disconnect from.
  • the disconnector contact socket 32 on the right of the disconnector piston 30 is linked to a busbar 35 or a cable end, while the earthing contact socket 42 vertically above the earthing piston 40 is linked to the GIS enclosure 45.
  • the DES 10 is connected on the left to an electrical conductor 55 extending through a respective section of the tubular compartment in the GIS 100. It will be appreciated that other orientations of the DES 10 are also possible.
  • the DES 10 is shown in the configuration where both the disconnector and earthing pistons 30, 40 are in the retracted position, and flush with the housing 11, in particular with the cylinder openings 13A, 14A at the front end of the cylinders 13, 14.
  • flush it is meant that the front end of the piston 30, 40, is aligned, at least substantially, with the opening 13A, 14A of the housing 11 from which it can extend, which in this embodiment is the front end of the cylinder opening 13A, 14A.
  • the front end of the piston 30, 40 and the front end of the cylinder opening 13A, 14A are both generally planar and lie in the same plane when the piston 30, 40 is in the retracted position.
  • the DES 10 further comprises an actuating mechanism 20 within the housing 11 comprising a crankshaft 28 and piston rods 23, 24 for operating the pistons 30, 40.
  • a main journal 21 of the crankshaft 28 can be seen protruding out of the housing 11.
  • an actuating device such as a motor or hand-crank
  • the rotary motion is converted to linear motion of the pistons 30, 40 to move them into and out of contact with their respective electrical contact sockets 32, 42.
  • the housing 11 and the pistons 30, 40 of the DES 10 being made of metal, the electrical conductor 55 of the GIS 100 can be disconnected and earthed by operating the actuating mechanism 20. So as to provide a better understanding of the actuating mechanism 20, it will be discussed in further detail below with reference to figures providing cross-section views of the DES 10.
  • FIG. 2A shows a cross-sectional view of a DES 10 revealing part of the components of the actuating mechanism 20.
  • the actuating mechanism 20 is a single actuating mechanism 20 for operating both pistons 30, 40, and comprises a crankshaft 28 extending along and rotatable about a crank axis, the crankshaft 28 comprising two main journals 21, 27 extending along the crank axis, two main webs 22, 26 extending from the main journals 21, 27, and two crankpins 23A, 24A provided between the main webs 22, 26.
  • the crankpins 23A, 24A extend along axes parallel to the crank axis, but the axis of one crankpin 23A, 24A has a phase offset to the other relative to the crank axis.
  • crankpins 23A, 24A are provided in a split-crankpin arrangement, interconnected by a crankpin web 25 extending therebetween, also forming part of the crankshaft 28.
  • the crankshaft components do not move relative to each other.
  • the actuating mechanism also comprises piston rods 23, 24 rotatably mounted on each crankpin 23A, 24A connecting the crankshaft 28 to the pistons 30, 40.
  • one main journal 21, one main web 22, the disconnector piston rod 23 (and the position of the disconnector crankpin 23A) are components of the actuating mechanism which can be seen.
  • the crankpin web 25 interconnecting the crankpins 23A, 24A is also visible.
  • Figure 2C however provides a view from the reverse side of the same cross-section as in figure 2A , and here the other main journal 27, the other main web 26, the earthing piston rod 24 (and the position of the earthing crankpin 24A) are components of the actuating mechanism 20 for the earthing piston 40 which can be seen, but not entirely those of the disconnector piston 30.
  • the actuating mechanism 20 of the DES 10 can also be seen in Figure 3 .
  • the crankshaft 28 which may be provided as an assembly of multiple parts or as a single unit, is mounted to the housing 11 of the DES 10 so as to be rotatable about the crank axis.
  • the crank axis extends perpendicularly to a plane parallel to both axes of the piston 30, 40, and therefore, in this case, to the plane in which the axes of both the disconnector piston 30 and the earthing piston 40 lie.
  • the crank axis intersects the axes of both pistons 30, 40, and therefore, in this case, goes through the intersection of the axes of the two pistons 30, 40.
  • the crank axis is located behind the back end of both pistons 30, 40 when they are in the retracted position.
  • the actuating mechanism 20 is arranged such that rotation of the crankshaft 28 can place the pistons 30, 40 in three distinct configurations.
  • both the disconnector piston 30 and the earthing piston 40 are in the retracted position; shown in figures 2A and 2C (view from the reverse side).
  • the disconnector piston 30 is in the extended position while the earthing piston 40 is in the retracted position; this is shown in figure 2B , which provides the view from the same side as figure 2A .
  • the disconnector piston 30 is in the retracted position while the earthing piston 40 is in the extended position; this is shown in figure 2D which provides a view from the same side as figure 2C .
  • each piston When in the configuration where both pistons are in the retracted position, each piston is not connected to its electrical contact socket 32, 42 and is flush with the housing 11. In particular, each piston 30, 40 is flush with the cylinder openings 13A, 14A where the piston 30, 40 can extend from.
  • This retracted position is the same position that a piston 30, 40 will be in when in the configurations where the other piston 40, 30 is in the extended position.
  • the GIS 100 is arranged such that the pistons of the DES 10 connect to, completely or as designed, the electrical contact socket 32, 42 when a piston 30, 40 is in the extended position.
  • the description will commence with the configuration where both pistons 30, 40 are retracted.
  • the disconnector piston 30 and the earthing piston 40 are both flush with the DES housing 11.
  • the crankshaft 28 When the crankshaft 28 is rotated anticlockwise about the crank axis (w.r.t. figure 2A ), it pushes on the disconnector piston rod 23 which in turn causes translation of the disconnector piston 30 within its cylinder 13, causing it to extend out of the cylinder opening 13A towards its disconnector contact socket 32.
  • Figure 2B shows the disconnector piston 30 in the extended position, where it engages the disconnector contact socket 32 and thereby places the electrical conductor 55 of the GIS in electrical contact with the busbar 35 or a cable end.
  • the DES 10 is most often in this position during normal operations, where it allows the flow of electricity across the relevant section of the GIS 100.
  • crankshaft 28 has made a rotation of 120°. While the disconnector piston 30 has been displaced from its retracted position to its extended position, it has done so with the disconnector piston rod 23 remaining on the same side of the crank axis (the disconnector crankpin 23A remaining on the same side of the axis of the disconnector piston 30); see figures 2A and 2B . Meanwhile, the earthing piston rod 24 has cut across the crank axis (the earthing crankpin 24A now being on the other side of the axis of the earthing piston 40); see figures 2C and 2B to visualise.
  • the angle of the main webs 22, 26 relative to the crank axis are not necessarily the same, and correspond to the phase offset of the crankpins 23A, 24A.
  • the earthing crankpin 24A linked to the earthing piston rod 24 has moved around the crank axis to an opposite corresponding side of crank axis with respect to the earthing piston axis. Consequently, the earthing piston 40 which was initially flush with the housing 11 with the disconnector piston 30 in the retracted position, is again flush with the housing 11 with the disconnector piston 30 in the extended position. In between, the earthing piston 40 has dipped behind the cylinder opening 14A.
  • the disconnector piston 30 Before the DES 10 can be earthed, the disconnector piston 30 must at first be disconnected from the disconnector contact socket 32 for safety reasons. So as to disconnect the disconnector piston 30, the crankshaft 28 is rotated clockwise 120° about the crank axis (w.r.t. figures 2A and 2B ). This retracts the disconnector piston 30 until it is in the retracted position flush with the housing 11, and with the earthing piston 40 also being in the retracted position, the earthing crankpin 24A having moved back to the initial position shown in figure 2A . In this configuration, both the disconnector piston 30 and the earthing piston 40 are again in the retracted position flush with the DES housing 11.
  • crankshaft 20 has made a rotation of a further 120°. While the earthing piston 40 has been displaced from its retracted position to its extended position, it has done so with the earthing piston rod 24 remaining on the same side of the crank axis (the earthing crankpin 24A remaining on the same side of the axis of the earthing piston 40); see figures 2C and 2D . This time however, the disconnector piston rod 23 has cut across the crank axis (the disconnector crankpin 23A now being on the other side of the axis of the disconnector piston 30); see figures 2D and 2A to visualise.
  • the disconnector crankpin 23A linked to the disconnector piston rod 23 has moved around the crank axis to an opposite corresponding side of crank axis with respect to the disconnector piston axis. Consequently, the disconnector piston 30 which was initially flush with the housing 11 with the earthing piston 40 in the retracted position, is again flush with the housing 11 with the earthing piston 40 in the extended position. In between, the disconnector piston 30 has dipped behind the cylinder opening 13A.
  • crankshaft 28 In order to place the disconnector piston 30 back in contact with the disconnector contact socket 32, the crankshaft 28 needs to be rotated back in the clockwise direction (anticlockwise in the view shown in figure 2A and 2B ). It should also be noted that the DES 10 is arranged such that continuous rotation of the crankshaft 28 is mechanically blocked in both directions, preventing the disconnector piston 30 and the earthing piston 40 from being extended out from the housing 11, or being in the extended position, at the same time.
  • crankpins 23A, 24A being provided with a phase offset to each other relative to the crank axis in this embodiment permits each piston 30, 40 to be in their extended position with their piston rod 23, 24 parallel to the piston axis (maximum reach), while the crankpin 24A, 23A of the other piston is located such that the other piston 40, 30 is in the retracted position.
  • the GIS 100 such that the pistons 30, 40 of the DES 10 are flush with the housing 11 when in their retracted position and to position the DES or electrical contact sockets 32, 42 so that the pistons 30, 40 are connected to their electrical contact sockets 32, 42, completely or as designed, when in their extended position.
  • FIG. 1 shows the three-phase GIS 100
  • three separate DES 10 are arranged side-by-side in the same orientation, each one intended for disconnecting and earthing one of the three electrical conductors 55 in the GIS 100.
  • Each DES 10 functions as previously described, however the crankshafts 28 of the three DES 10 are connected to each other forming a common crankshaft 28 and the three DES 10 can be operated synchronously.
  • Figure 3 provides a perspective view of the three DES 10 with the housing 11 of each DES 10 mostly stripped away, showing the actuating mechanisms 20 linked by a common crankshaft 28.
  • the common crankshaft 28 will be arranged such that it does not conduct electricity between the three electrical conductors 55, and again may be provided as an assembly of multiple parts, or as a single unit.
  • the pistons 30, 40 of all three DES 10 and their actuating mechanisms 20 may be provided in a common housing.
  • the invention is also applicable to single-phase GIS where just one DES 10 needs to be provided at relevant sections of the GIS. It will also be appreciated that existing GIS can readily be retrofitted so as to provide a GIS 100 according to the present invention.
  • the GIS 100 of the present invention thus allows the disconnector piston 30 and earthing piston 40 to be operated while causing less dielectric stress.
  • the provision of the crankshaft 28 neatly enables the pistons 30, 40 to be in the retracted position while the other is in the extended position or the retracted position.
  • crankshaft 28, unlike a straight rotary shaft, does not run along the crank axis for its entire length means that it frees up space along and around the crank axis. This crucially allows the crankpin 23A, 24A and piston rod 23, 24 to occupy corresponding positions on both sides of the crank axis, enabling the piston 30, 40 to be flush with the housing 11 in the retracted position.
  • the crankshaft 28 By having one piston 30, 40 in the retracted position flush with the housing 11 while the other is in the extended position, the dielectric stress at the openings 13A, 14A of the housing 11 is significantly reduced.
  • the pistons 30, 40 being arranged not to extend from housing 11 while the other 40, 30 is moving between the retracted position and the extended position also contributes to this.
  • the crankshaft 28 being located in the DES 10 with the crank axis extending perpendicularly from a plane parallel to the two piston axes, and intersecting the two piston axes, allows for a compact construction.
  • a reduction in part-count of the DES may also be realised.
  • pistons are angled at 90° to one another, they may alternatively be provided at a different angle to each other, e.g. between 60° and 150°.
