Definitions

  • the subject of the invention is a fuse switch, especially a detachable, three-phase low voltage strip fuse switch.
  • Fuse switches are used to protect electrical installations and to disconnect circuits in a safe and controlled manner. Fuse switches are used in distribution networks of residential and industrial buildings.
  • the parked position is a state of the switch in which the fuse cartridges have been slid out from the contacts to a safe distance, thereby opening the circuit(s).
  • the manipulator e.g., a lever
  • the parked position is a state in which circuits are prevented from being closed by accidentally applying forces to accessible parts of the fuse switch. It is also advantageous to be able to mechanically secure the manipulator (lever) in this position with a padlock or other similar lock.
  • the parking action is not very intuitive and requires knowledge of the operating instructions, and above all, it requires carrying out several, often complicated, activities.
  • the Polish patent PL215231B1 or PL220874 B1 discloses a switch, especially a detachable, three-phase low voltage strip fuse switch.
  • the switch includes a complete base, a complete housing, and a complete drive.
  • the housing is equipped with guides into which the drive guidewire strips slide.
  • the drive includes a handle and a cap that is slidably mounted in the upper part of the handle.
  • there are cutouts on the side surfaces of the handle that cooperate with appropriate pegs placed in the guide.
  • the parking state of the switch is obtained by opening the switch and pressing the lock release in the guide and then moving the handle as in the closed position of the switch. Additionally, there is a bow on the front surface of the handle that allows the user to install a mechanical lock or padlock and seal the switch in the closed and parked position.
  • a power connection device is known from the description of the Polish patent PL200078B1 .
  • the device includes a housing, a busbar terminal, a junction box movable relative to the housing and a switching lever.
  • the lever contains side plates on which the pivot plug and bearing plug are arranged.
  • the pivot plug is inserted into the first longitudinal recess on the side wall of the housing, and the bearing pin into the second recess, parallel to the first one. This design of the device ensures the possibility of swinging movement of the lever.
  • To disconnect the device the lever is grasped and turned clockwise, and the junction box and locking element are pulled upwards.
  • the user should tilt the locking element's tilt button to the left, raise the junction box further upwards and then fold the lever to the starting position. In this position, the junction box cannot be pulled further upwards, nor can it be pushed downwards without the reactuation of the locking element.
  • European patent document EP1993116B1 covers a fused power switch block.
  • the device comprises a lower and an upper part connected to each other via a mounting element. Additionally, a switch cover is attached to the upper part, which has a hole through which a screwdriver can be inserted and directed towards the mounting element.
  • the disclosed power switch block also includes a switch lever that is attached to the switch cover. To obtain the opened position, the switching lever must be moved from the closed position to the tilted position. In this arrangement, it is possible to insert a mounting element into the cover without having to dismantle it.
  • the technical problem discussed this invention is to propose a fuse switch that will ensure a quick and easy change of the switch into the parked position. Additionally, it is desirable that the parked position of the fuse switch is stable and safe in order to minimize the likelihood of accidental re-closing of the circuits as much as possible. Moreover, it is desirable that the size of the device in the closed position of circuits and in the parked position is small, while maintaining a compact structure. It is also desirable that access to the individual functional elements of the fuse switch in the parked position is quick and easy. In addition, it is desirable that the design of the fuse switch provides the possibility to additionally secure its parked position.
  • the subject of the invention is a fuse switch containing a base, a body supported on it, a cassette placed in the body and a lever rotatably connected to the body via a connector, characterized by the fact that it additionally includes a guide rail arranged parallel to the body, with the guide rail on its inner surface, in its central region, is arranged a first pin cooperating with a first guide groove arranged on the side surface of the lever and cooperating with a second guide groove arranged on the side surface of the cassette, the guide rail being able to move vertically relative to the body, the first guide groove being formed from an arc-shaped disconnecting segment and an arc-shaped parking segment.
  • the guide rail is additionally capable of being moved horizontally relative to the body.
  • the first guide groove is substantially L-shaped.
  • the second guide groove is arc-shaped.
  • the lever in the closed position of the circuits of the fuse switch, the lever extends substantially parallel to and adjacent to the guide rail which is in the lower position, and the first pin is disposed at the end region of the disconnecting segment and at the first end region of the second guide groove, wherein the lever, in the opened position of circuits of the fuse switch, extends substantially perpendicular to the guide rail which is in a vertically and horizontally displaced position relative to the body, and the first pin is arranged in the connecting region of the disconnecting segment and the parking segment and in the second end region of the second guide groove, wherein the lever, in a position of the parked fuse switch, extends obliquely relative to the guide rail which is in a vertically and horizontally displaced position relative to the body, and the first pin is arranged in an end region of the parking segment and in a second end region of the second guide groove.
  • a mounting region is arranged in the second end region of the first guide groove.
  • a third guide groove is provided around at least one end of the body, in which a second pin coupled to the cassette is placed.
  • the second pin is the axis of the gear wheel, the teeth of which cooperate with the first toothed rack arranged on the inner surface of the body.
  • At least one second toothed rack is arranged on the outer surface of the cassette and cooperates with the teeth of the gear wheel.
  • a cam is provided on the circumference of the gear wheel which is in contact with the resistance region of the guide rail.
  • the cam has a third pin which is positioned in a fourth guide groove disposed in the region of at least one end of the cassette.
  • the fuse switch has a structure symmetrical with respect to a vertically oriented plane passing through the longitudinal axis of the fuse switch.
  • the fuse switch according to the invention ensures quick and easy change of the switch to the parked position due to the favourable shapes of the construction elements and their functional connection in the form-guide mechanism of the device. Due to the presence of a lever equipped with a first guide groove and a cassette with a second guide groove, which are engaged with the first pin located on the inner surface of the guide rail, it is possible to move the lever in an arc of approximately 140° relative to its lower position, i.e., when the circuits of the fuse switch are closed. This design ensures that the switch can be brought to the parked position with one lever movement. This means that disconnection and parking of the fuse switch is essentially performed in one smooth movement of the lever.
  • a set of toothed elements such as the body gear wheel cooperating with the body toothed strip and/or the cassette toothed strip, facilitates efficient movement of the lever in an arc and movement of the guide rail in the horizontal and vertical direction relative to the base. Due to the presence of a second pin in the central region of the gear wheel, which is coupled to the third guide groove of the body, it is possible to guide the vertical movement of the gear wheel and guide rail.
  • the third pin of the gear wheel is functionally connected to the resistance region of the guide rail via a hole and the fourth guide groove, thus forming a toothed arm, the operation of which significantly facilitates the movement of the lever in an arc and brings the fuse switch to the parked position.
  • the lever In the parked position, the lever is in a diagonal position to the base of the fuse switch with its end resting on the rail, further reducing the likelihood of it accidentally catching and moving the lever back to the down position.
  • the dimensions of the fuse switch are such that the device takes up relatively little space and can be installed in hard-to-reach places.
  • the lever diagonally to the fuse switch body in the parked position access to the cover is free and ensures easy manipulation of functional elements by the user.
  • By arranging the lever diagonally to the base in the parked position it is also possible to secure the movement of the lever by using a padlock or seal, which additionally protects the device against accidental closing of the circuits.
  • the opening of circuits is equivalent to the parking of the fuse switch, it is an intuitive operation and does not require careful reading of the user manual.
