Definitions

  • the invention relates to a method for inserting or removing a tolerance insert in a magnetic chamber of a switching device.
  • switching devices in particular low-voltage switchgear, the current paths between an electrical supply device and consumers and thus their operating currents can be switched.
  • the connected consumers can be reliably switched on and off.
  • a low-voltage electrical switching device such as a contactor, a circuit breaker, a motor branch or a compact starter, for switching one or more current path (s) one or more so-called main contacts or auxiliary contacts, of one or more actuation magnets, ie electromagnetic drives, can be controlled.
  • the main or auxiliary contacts each consist of a movable contact, in particular a contact bridge, and a fixed contact or a fixed contact piece, to which the consumer and the supply device are connected.
  • a main or auxiliary contact is a corre sponding Given switching on or off signal to the actuating magnet, whereupon this acts with its armature on the movable contact, that the movable contact or the contact bridge performs a relative movement with respect to the fixed contact and either closes or opens the current path to be switched.
  • contact surfaces are made of materials, such as silver alloys, which at these locations on both the movable contact, i. the contact bridge, as well as on the fixed contact, i. the contact piece, are applied and have a certain thickness.
  • these mechanical switching devices Due to the required part tolerance, these mechanical switching devices have a tolerance insert with which the through-pressure of the switching contacts can be adjusted. By adjusting the paths and pressures can be adjusted to a relatively accurate level, whereby the magnetic paths can be kept small in the device. This makes it possible to minimize the power loss of the devices.
  • the adjustment of the switching devices by a different thickness tolerance insert which is inserted into the self-contained magnetic chamber, performed.
  • the Fig. 1 and 2 show this with the example of a contactor.
  • the paths and pressures are determined in this example. If these are outside the desired limits, the tolerance insert 2 must be replaced by thicker or thinner tolerance liners.
  • This arrangement has the disadvantage that after the switching device 1 has been mounted and measured, the tolerance insert 2 must be replaced again.
  • the switching device 1 must be dismantled again and reassembled again. That is, to another tolerance insert 2 below the spring element 6, which is arranged below the actuating magnet 4, to mount, the actuating magnet 4 and the spring element 6 must be removed from the magnetic chamber 3.
  • the EP 0 487 069 A2 discloses a switching device, wherein the magnetic chambers - ie the space between the end plates of the coil module - has a mounting opening for inserting or removing a tolerance insert.
  • the present invention has for its object to provide a method which allows switching devices can be fully automatically adjusted.
  • a switching device in particular low-voltage switching device, with a provided in a magnetic chamber actuating magnet, which is fixed by at least one spring element in the magnetic chamber, with at least one movable switching contact and at least one fixed switching contact, said at least one movable switching contact by the actuating magnet movable wherein the magnetic chamber has a mounting opening for inserting or removing a Toleranizeinlage.
  • Such a switching device makes it possible to carry out the adjustment of the switching device after the final assembly and measurement of the switching device.
  • This is made possible, in particular, by the fact that the magnet chamber has a mounting opening for inserting or removing a tolerance insert.
  • To insert the tolerance insert into the mounting hole or to remove it from an actuating element is inserted into the mounting hole.
  • the actuating element engages the actuating magnet within the magnet chamber and presses or pulls it in the direction of the spring element which is disposed below the actuating magnet.
  • the spring element is compressed due to the force exerted on the spring element. This creates a free space in the upper area of the magnetic chamber, a so-called gap. In the free space a tolerance insert can be inserted, which serves for the adjustment of the switching device.
  • the tolerance insert is inserted through the mounting hole in the space. After inserting the tolerance insert, the actuating element, which has held the actuating magnet, is removed from the magnet chamber, so that the actuating magnet is pressed in the direction away from the spring element due to the spring force of the spring element. The upper portion of the actuating magnet abuts the inserted tolerance insert. After inserting the tolerance insert, the paths and pressures of the contacts can be determined. If it is found that these are outside the desired limits, the tolerance insert can be easily replaced by a corresponding thinner or thicker tolerance insert. For this purpose, only the actuating magnet must be moved by means of the insertable through the mounting opening actuating element in the direction of the spring element. Thereafter, the tolerance insert can be removed from the magnetic chamber and the new tolerance insert inserted.
