Definitions

  • the present invention relates to a fuse-disconnecting switch which is provided with a casing with connections to and from respective fuse-link cartridges which are dismountably provided in said casing.
  • International IEC-regulations define various categories of electric switches, e.g. AC3 for operation of single motors, AC23 for operation of motors in groups, and AC22 for a mixed load (e.g. motors and a resistive load). This means that a device for AC22 operation may have a simpler structure (switching function) than devices for AC23 and AC3 categor­ies.
  • the fuse load-disconnecting switch is characterized by the fact that said connections are provided with a switch connection either in front of or both in front of and behind respective fuse-link cartridges, and that the poles of the switch connections in respective connections are provided in series, one behind the other, along a common operation rod influencing the respective switch connections simultaneously.
  • FIG. 1 a fuse load-disconnecting switch 1 which has cartridge fuse-links 2, 2′, 2 ⁇ is shown.
  • the switch is of the AC3/AC23 (SMR) type, which has a break both in front of and behind the fuse, i.e. both in the connection to and from the fuse-link cartridge.
  • SMR AC3/AC23
  • the switch connection thus, provided for fuse 2 is designated by numeral 3, and in the lead from the fuse the switch connection is designated by numeral 3′.
  • Corresponding numerals for fuse 2′ are 4 and 4′, and for fuse 2 ⁇ numerals 5, and 5′, respectively, are used.
  • a spring mechanism 13 may be provided to ensure the necessary contact pressure for current transfer to stationary member 12 of the switch.
  • terminals 6, 6′, 6 ⁇ are provided at a certain mutual distance, e.g. equal to 50 mm in the elected embodi­ment.
  • terminals 7, 7′, 7 ⁇ are also provided at a mutual distance equal to 50 mm.
  • cartridge fuse-links are firmly held by clamping means 14, known per se, cf. Figure 2.
  • clamping means 14 known per se, cf. Figure 2.
  • a microswitch 15 may be provided to sense the operative state of the switch.
  • Figure 4 in many ways corresponds to that of Figure 1, apart from the fact that terminals 7, 7′, 7 ⁇ are replaced by cable connection terminals 16, 16′, 16 ⁇ .
  • terminals 6, 6′, 6 ⁇ are, furthermore, provided at a certain mutual distance, in the elected embodiment equal to 185 mm.
  • Said two mutual distances, 50 and 185 mm are calculated to simplify the use of the switches in various panels and systems without much need for adaption.
  • the most common panel systems roughly have the following busbar dimensions: Thickness 5 mm - Distance of busbars 50 mm, Thickness 10 mm - Distance of busbars 100 mm, and Thickness 10 mm - Distance of busbars 185 mm.
  • Figure 6 shows another variant of the embodiment of Figure 1, in which terminals 6, 6′, 6 ⁇ are provided as shown in Figure 1, but in which terminals 7, 7′, 7 ⁇ are replaced by terminals 16, 16′, 16 ⁇ , as shown in Figure 4, with terminals 6, 6′, 6 ⁇ in Figure 6 having a mutual distance of 50 mm in stead of what is shown in Figure 4, viz. a mutual distance of 185 mm.
  • terminals 6, 6′, 6 ⁇ in Figure 6 having a mutual distance of 50 mm in stead of what is shown in Figure 4, viz. a mutual distance of 185 mm.
  • operation and structure of Figure 6 correspond to the embodiments of Figure 1 and Figure 4.
  • terminals 6,6′ ,6 ⁇ have a mutual distance which is preferably 185 mm.
  • Figure 8 shows a minor variant of the concept of Figure 7.
  • Contact terminals 6, 6′, 6 ⁇ are there provided at a mutual distance of 50 mm, whereas the leads from respective fuse-­link cartridges are connected with previously mentioned terminals 16, 16′, 16 ⁇ , via internal current-carrying connections, as shown.
  • the present invention provides the unique situation that it will be possible to mix devices which are selected for their application, within the same panel area of the devices without converting busbars and areas. To the user this will be a more inexpensive concept, besides providing for a more optimal utilization of the said panel area.
  • the SER kind (SER only having a break in front of or in the feed line to the fuse-link cartridge), has fewer contact joints than SMR which has a break both in front of and behind the fuse-link cartridge. Total loss of efficiency and increase of temperature from SER will, thus, be considerably lower than in case of SMR.
  • the indicated concept will, thus, permit providing a switch device panel area with more exits of switches of the SER kind than of the SMR kind.
  • a locking mechanism must be present to prevent the protective cover 17 across fuses 2, 2′, 2 ⁇ from being opened when the switch is on. This is a safety measure to prevent the incompetent from access to live portions. With a disconnected switch, however, the fuses are dead and there is no danger when the cover across them is opened and fuses are accessible. In order to check the state of voltage in the plant, a skilled electri­cian, however, needs access to the fuses when the switch is connected. This problem is solved by the fact that a skilled person may use a tool, e.g. a screw driver to release a locking mechanism 18 and 21 on the fuse cover.
  • a tool e.g. a screw driver
  • an arm 19 (Figure 9), 20 ( Figure 11) is provided on said operation rod to be movable with said rod and project towards the front of the switch.
  • arm 19 will cause engagement with a locking pin 21 on the cover 17 when the switch is in an operative state, so that cover 17 cannot be opened when the switch is in an operative state.
  • This represents an additional safety measure against undesired opening of the cover when the switch is live.
  • there is an engagement in the concept of Figure 11 between arm 20 and a locking pin 22, so that cover 17 cannot be opened as long as there is an engagement between arm 20 and pin 22.
  • lock 18 thus, represents an additional safety measure even though engagement of members 19, 21, and 20, 22, respectively, is sufficient for normal operation.
