Definitions

  • the invention relates to a slide-in bar with surge arresters for isolating strips, consisting of a cassette-like insulating material housing with receptacles for the surge arresters, each of which is connected to a common ground bar via a fusible element and a ground contact and is held interchangeably in the housing receptacles by means of compression springs.
  • surge arresters in the form of plug-in cassettes or plug-in strips are used, which in the event of prolonged overcurrent by melting a melting element, lay the conductors at earth potential.
  • Such a slide-in bar with surge arresters of the type specified is in DE-AS 24 28 266 described by the applicant and consists of a two-shell plastic housing in which ten recesses are offset in two rows.
  • a surge arrester can be inserted by hand from the outside into each recess.
  • the individual surge arresters are held in the housing recess by a compression spring arrangement in which a compression spring arranged in a shell-shaped housing bulge presses a tapping contact which is arranged in the housing in a longitudinally displaceable manner against an end face of the cylindrical surge arrester. Under the spring pressure, the surge arrester is supported by a fusible element on a ground contact, which is formed as a bent attachment on a continuous common earth strip.
  • This known slide-in bar has found wide use because it is inexpensive to manufacture and easy to use. Just like other known designs according to e.g. B. DE-OS 19 29 845, DE-OS 25 55 394, DE-PS 1 196 281 and CH-PS 507 599, however, this known slide-in bar cannot be used in conjunction with so-called two-way arresters, which each replace two conventional arresters.
  • the object of the invention is to provide a slide-in bar with surge arresters for. B. to create isolating strips of the type mentioned, which enables the use of two-way surge arresters.
  • the surge arresters each have three electrodes, each of which is connected to a connecting pin, that the connecting pins engage in clamping contacts, of which the two lateral clamping contacts are each connected to an externally accessible tapping contact and the central clamping contact is connected to the U-shaped earth strip, that the melting element is arranged in the form of a solder pill between the middle electrode and a ground rail which is connected to the ground strip and is accessible from the outside - with the interposition of the compression spring arrangement - and that the compression spring arrangements accessible via housing openings for resilient mounting of the overcurrent arrester have electrical contact elements which are assigned to the lateral electrodes of the overcurrent arrester and are opposite to each other with an intermediate distance in normal operation.
  • the respective compression spring arrangements each consist of two mutually guided, cup-shaped metal housing halves, between which a spreading spring in the form of a helical spring is accommodated.
  • the contact elements are fastened in the form of laterally protruding spring clips and the solder pill rests under the spring pressure on the outer surface of this metal housing half.
  • the lower half of the metal housing is supported on a support surface of the earth rail.
  • each overcurrent arrester 1 has three connecting pins a, b, c, which are inserted lengthways into a clamping contact 2, 3, 4 formed by longitudinal spring tongues.
  • the two lateral connecting pins a and c are connected to lateral electrodes 12 ', 12 "and the middle connecting pin b is electrically conductively connected to a central electrode 12 of the respective overcurrent arrester 1.
  • the two lateral clamping contacts 2, 4 for receiving the connecting pins a, c are electrically and mechanically connected to tapping contacts 5, 6 which are connected to the corresponding contacts of the isolating strip.
  • the middle pin b engages in the middle terminal contact 3, which - together with another middle terminal contact 3 for the other two-way surge arrester 1 - is connected to a continuous, common earth strip.
  • the earth bar 7 has egg ne U-shape, with its two parallel legs extending in the plastic housing over almost its entire length and the lower leg in Fig. 1 is designed as an outwardly projecting ground rail 8.
  • Each two-way Studentsstromableiter 1 is overall by a compression spring arrangement 10 in the plastic housing 20 - hold, where between this spring assembly 10 and the lower surface in the drawing of the two-way attached überstromableiters a solder pellet. 11
  • the compression spring arrangement 10 consists of two metal housing halves 13, 14 which are designed as nets which can be shifted into one another and can be displaced relative to one another by a compression spring arranged in their interior.
  • the maximum expansion path of the compression spring arrangement 10 which can be achieved by the compression spring 10a is limited by stop hooks 15, 16 which are fastened to each of the two housing halves 13, 14 and engage in one another (cf. left part of FIG. 1).
  • the two lateral electrodes 12 ′, 12 ′′ of the two-way overcurrent arrester 1 are each opposite two contact elements 17, 18 at a predetermined intermediate distance, which is slightly smaller than the height of the solder pill 11, which act as separate spring elements or as part of the stop hooks 15 , 16 can be formed and are firmly connected electrically and mechanically to the upper metal housing half 13 of the compression spring arrangement 10.
  • the ground rail 8 has a support 19 on which the lower metal housing half 14 is located in direct contact.
  • the plastic housing 20 consists of the actual housing 22 on which a plastic cover z. B. is attached by ultrasonic welding in a single operation.
  • stops 23 are formed on one end of the housing part, which limit the insertion path of the bar.
  • the solder pill 11 attached to the surface of the upper metal housing melts, as a result of which the contact clips 17, 18 come into conductive connection with the electrodes 12 ', 12 "and thus are short-circuited together with the center electrode via the electrically conductive compression spring arrangement with the grounded busbar will.
  • the current flows from the tapper 5 or 6 via the electrodes 12 'or 12 "to the center electrode 12.
  • the electrodes 12, 12', 12 there is a gas which, when the voltage rises, forms an arc ionized and thus becomes conductive.
  • the current flows from the central electrode 12 via the solder pill 11 to the earth rail. If this condition lasts longer, the solder pill 11 melts, as a result of which all three electrodes 12, 12 'and 12 "are short-circuited and damage to the arresters and other dangers are avoided.
  • the current can flow to the ground busbar in two ways, namely one - as the main route - via the. Tapping contacts 5, 6, the short-circuited distance from the respective outer electrode 12 'or 12 "via the center electrode 12 to the ground contact rail and on the other hand from the respective tapping contact 5 or 6 via the assigned external electrode 12' or 12" directly to the ground contact rail. This two-way derivation increases operational safety considerably.
