Definitions

  • the invention relates to a method for adjusting holding magnet releases, in particular those for residual current circuit breakers.
  • Residual current circuit breakers are usually built today with a holding magnet release for cost reasons and to achieve small tripping currents.
  • the holding magnet release must be set to a certain sensitivity so that the required tripping current of the residual current circuit breaker is achieved together with the differential converter.
  • a known method for adjusting the sensitivity is the regulation of the permanent flow, which e.g. by turning or moving the permanent magnet (see AT-PS 242 777).
  • the permanent flux changes over the tripping armature and thus the current that has to be passed through the field winding to weaken the permanent flux over the tripping armature to such an extent that the tripping armature falls off the yoke body due to the pulling action of the tripping spring.
  • the automation of this known adjustment method is costly and must either take place at the open residual current circuit breaker or the residual current circuit breaker is equipped with an adjustment opening which has to be closed after the adjustment in order to prevent unauthorized intervention.
  • the invention is based on the object of specifying an adjustment method which can also be carried out on the fully assembled, completely closed residual current circuit breaker and which does without any movement of the permanent magnet.
  • the holding magnet release is brought into a magnetic field, which is preferably rotated step by step until the magnetization of the permanent magnet and thus the permanent flux through the release armature of the holding magnet release is changed so far that the release armature at a predetermined current through the excitation winding falls off the yoke body, ie the holding magnet releases.
  • the procedure according to the invention is preferably such that the holding magnet release is brought into the region of two mutually perpendicular magnetic fields and that the resulting magnetic field is rotated by preferably gradually changing the strength of the magnetic fields.
  • This embodiment can be carried out with permanently mounted coils and is particularly suitable for automation because the rotation of the resulting magnetic field can be done simply by changing the current in at least one partial coil.
  • the adjustment in the resulting magnetic field A cheese is also particularly inexpensive because there are no spatial problems with the power supply lines for the residual current circuit breaker in which the holding magnet release to be adjusted is installed.
  • a residual current circuit breaker 1 is brought into the interior of a cheese 2 with a holding magnet release.
  • a permanent magnet 3 shown in broken lines in the holding magnet release. If current flows through both partial coils 2a, 2b of the cross-wound coil, a corresponding magnetic field with direction A arises with a corresponding winding direction, with a reversed partial coil 2a a magnetic field in direction C.
  • Any resulting magnetic fields can be achieved in all directions between A and C by unequal currents in the partial coils 2a and 2b.
  • the magnetic field can thus be "rotated” by changing the currents in the partial coils 2a and 2b.
  • the permanent magnet 3 After switching off the current flowing only very briefly through the partial coils 2a and 2b, the permanent magnet 3 keeps the magnetic field in the desired direction. The same effect is therefore achieved as if the permanent magnet magnetized in a certain direction would have been physically rotated in accordance with the known adjustment method.
  • the residual current circuit breaker 1 can be held and switched on by a device (not shown) and can be switched into a tripping circuit by contacts (not shown).
  • the tripping current of the earth leakage circuit breaker 1 is now adjusted by repeatedly rotating the cross coil magnetic field, turning the switch on and measuring the tripping current until the predetermined tripping current is reached.
  • This adjustment process can be carried out without difficulty by a processor-controlled automatic system without human intervention.
