Definitions

  • the invention relates to a switching contact piece according to the preamble of claim 1.
  • the switch contact piece consists of a carrier, a solder layer arranged on the carrier for connecting solderable material of the contact material, which determines the usable erosion volume.
  • a contact system for an electrical switching device in which only one male piece is connected to a carrier rod by means of friction welding.
  • the object of the invention is to provide a switch contact piece according to the preamble of claim 1 and to find a method for its production which is technically and economically improved compared to the prior art.
  • Fig. 1 is a scarf contact piece
  • Fig. 2 shows the prior art.
  • the switch contact piece 1 for low-voltage switchgear with one with a carrier 2 and contact material 3, the contact material 3 being arranged directly on the carrier 2 without an intermediate solder layer 4 and without a solderable material 5 by means of a friction welding connection.
  • the switching device can be a circuit breaker, a motor protection switch or a contactor.
  • the friction welding connection is achieved by a rotational movement of at least 50,000 rpm, preferably 60,000 rpm, or by a rapid one Vibration movement is achieved, with torques and feed forces being detected and evaluated with the aid of sensors.
  • the friction welding process takes 0.1 to 1 second.
  • the friction welding connection is carried out in such a way that a chemical composite consisting of an electrode connection is formed, which prevents melting even in the event of arcing.
  • the process layer thickness is approximately 0.015 mm.
  • the carrier In the process for producing the switch contact piece, the carrier is firmly clamped while the contact material is set in motion.
  • the switch contact piece consists of a carrier 2, a solder layer 4 arranged on the carrier 2 for connecting solderable material 5 of the contact material 3, which determines the usable erosion volume. 10 to 20% of the contact material volume is lost as solderable material.
  • both the soldering and the solderable layer are omitted.
  • the full contact material volume is available as usable erosion volume.
  • the switchgear therefore has a longer service life.
  • the process capability is ensured due to the process.
  • the parameters are reproducible.

Abstract

L'objectif de l'invention est d'améliorer, en ce qui concerne la technique et les coûts de fabrication, par rapport à l'état de la technique, une pièce de contact de commutation pour appareils de commutation basse tension, comportant un support et un matériau de contact. Cet objectif est atteint par le fait que le matériau de contact (3) est placé directement sur le support (2) sans couches de brasure (4) intermédiaires et sans couches aptes au brasage (5), grâce à un soudage par friction. L'invention trouve des applications dans le domaine des commutateurs de puissance basse tension, des commutateurs de sécurité de moteurs ou des commutateurs-disjoncteurs.
