Definitions

  • This invention is about a miniature circuit breaker with electromagnetic and thermal breaker and that has one moving and one fixed contact, arc forming room and an arc diminishing room to where the arc is directed by an arc horn over the fixed contact unit and an arc director over the moving contact.
  • the arc formed by a short circuit generates high heat and gives harm in the area where it is formed and in its surrounding.
  • Arc roots and cones move away some metai particles from the surface. Rapid movement in both getting in touch and separating of the contact surfaces and especially maintaining a tight contact between the two contact surfaces during current transmittal affects the perfectness of the contacts and thus the quality in transmitting the current.
  • the gasses formed by high temperature and the mixture generally consisting of carbon, metal and oxides are dragged towards the gas exhausting hole and they accumulate in remote places especially between the arc forming room and the set up mechanism and in the direction of arc diminishing room.
  • the electrified area has to be converted into equal state of potential. And this can only be achieved by having the moving and fixed contacts in parallel position and then the improvement in isolation level can be foreseen. The accumulation of residuals is reduced and so the isolation is maintained by means of proper design of contacts and obtaining equal potential level.
  • the miniature circuit breaker shown in Figures 1, 2 and 3 consists of main modules such as Body (1) made of inflammable thermoplastic material, Fixed Side Unit (10) placed in the Cover (2), The Moving Side Unit (16), Arc Cell Unit (5) and other individual parts. Said individual parts and how they are installed are as follows:
  • the Joint (8) is installed onto the body (1) by means of a pin (30) and deformation translator wire (25),
  • the pre-mounted Set Up arm (3) and the Pressina lfte e (7) which are pre-mounted by means of a pin (31) are placed into the set up arm cell on the Body (1).
  • the Isolation Plate (6) is placed into the cell of the Body (1).
  • the contact driving plate (23) and press spring (24) together with the pin (32) are mounted on the Moving Contact (17) of the Moving Side Unit (16) consisting of the
  • the position indicator (9) is installed over the Pins (30,32) on the Moving Contact (17).
  • the Fixed Side Unit (10) consisting of Fixed Contact Carrier with Arc Horn (11), Contact (12), Chassis (13), Magnetic Coil (14) and Clamp Unit (15) is installed on the appropriate cell over the body (1).
  • Arc diminishing cell (5) consisting of 13 parallel positioned steel sheets, is placed in to the cell over the body (1), forming the third main module of the device. Finally the adjusting screw (26), Adjusting Nut (27), Press Spring (34) and the second Isolating Plate (6) are placed into their spaces. The cover (2) is placed over this unit and riveting (36) is applied at four points.
  • Fixed side unit 11. Fixed side carrier
  • Bimetal 20 Bimetal holder
  • the Set up Arm (3) on the front face ( Figure 3) is well located for proper functioning and has a decorative look.
  • the Set up Arm (3) may be sealed (locked) at both of its two positions.
  • the body (1), Cover (2) and the Clamps (22,11) are so designed that even all screws get loose, parts do not get apart.
  • the body (1) and the cover have bar mounting places.
  • To mount onto a bar the parts in Figure 3, indicated with I, are torn out.
  • the instrument is designed to comply with Standards of DIN EN 50022. Rail clip (28) is pulled back by help of a screwdriver and it stays at that position by means of a notch. When it is gently pressed with a screwdriver, it is released from the notch and it comes to the position to tighten the rail. This design gives a great help while mounting of the instrument or sliding mounted instrument on the rail.
  • the driving mechanism in the instrument transfers the action to the moving contact (17) by mean of the set up arm (3), so it provides immediate contact or depart of moving (17) and fixed (12) Contacts.
  • the driving (set-up) mechanism is seen in the open position in Figure 2.
  • the set up Arm (3) is leaned to the body (1) at this position.
  • the moving contact (17) leans to the arc director (21) with the help of joint (8), which is turned counter-clock, wise on the axis of the tension spring (33) and the pin (30).
  • the green area of the position indicator (9) is visible at the window over the cover (2).
  • the Set up Arm (3) is moved to the left hand side in the direction of the label (4). Together with this, press piece (7) contacts the contact drive plate (23) and turns the moving contact (17) in the clock wise direction on the axis of the pin (30).
  • Magnetic opening in case of a short circuit, is realised by a magnetic coil (14) moving the drive pin (37) designed in piston shape in the centre of the coil in right hand direction.

Abstract

Cette invention a trait à un disjoncteur miniature (fusible automatique) doté des fonctions de disjoncteur électromagnétique et thermique. On utilise ces disjoncteurs pour protéger la ligne ou des appareils connexes contre les courts-circuits et contre des appels de courant anormalement élevé affectant des lignes électriques. Ce dispositif, qui se compose d'un corps (1) et d'un couvercle (2) thermoplastiques inflammables produits par moulage par injection, est conçu de telle sorte que les doigts de l'utilisateur ne puissent pas atteindre les points sous tension. La face avant du dispositif est pourvue d'un arbre de bobinage (3) pour la mise en marche et la mise hors circuit, les deux faces étroites sont pourvues de pinces combinées (28) à monter sur les rails selon les normes DIN EN.
