Definitions
- the invention relates to arc quenching chambers for in air low-voltage circuit breakers, in particular reducing the number of fasteners needed to assemble them.
- Arc quenching chambers are particularly useful with large circuit breakers can only be manufactured as separate units. at their connection to the main body of the circuit breaker and the connection of their individual parts the task, the technically required column and Joints against the passage of ionized arc gases to seal and electrical arcing from possibly nevertheless to prevent escaping gases. In this respect, too Connection of the fire chamber cover to the fire chamber housing to pay special attention.
- an extinguishing chamber is shown in US-A 4,388,506, which removably arranged on an air circuit breaker is.
- the arcing chamber is on the side of the fixed contact by means of a hook-like extension inserted in a groove and on the side of the movable Switch contact fixed with the help of screws.
- the fire chamber cover but is also here with four screws on the housing attached to the arcing chamber.
- the hook-like extension serves this switch for fastening the entire arcing chamber and in addition, especially the seal against leaking ionized arc gases.
- EP patent application 0 225 207 describes an arc quenching chamber, where the arc extinguishers between two side walls provided with ribs and grooves, the molded half covers of the quenching chamber with an insulating Have bracket.
- the cover halves attached to a bracket with the help of screws, which in turn for attachment to the switch housing serves what is done with the help of fastening screws.
- apart from the multitude of individual parts of the quenching chamber themselves, are for fastening the arcing chamber to the switch
- the quench chamber cover with four screws attached to the extinguishing chamber housing.
- the fire chamber cover covers an extension of the arcing chamber housing, in which a single fastening screw captively housed with which the complete arc quenching chamber on Circuit breaker is attached.
- an insertion opening for a screwdriver arranged.
- the object of the invention is to design the arc quenching chamber so that it can be operated with simple Means and a small number of connecting elements be assembled from their individual parts can that the demands on the connection of their individual parts with each other, especially the sealing of the technically required Gaps and joints against the passage of ionized Switching gases and the prevention of electrical flashovers by possibly escaping gases become.
- Fixing the fire chamber cover on the fire chamber housing takes place with the help of only one fastening screw through a hole in the fire chamber cover and the hole in the passed through the hollow extension of the arcing chamber and into a corresponding one provided in the circuit breaker Thread is screwed in.
- the horizontal one is nose-like projection at the top of the extension, in which the hole for receiving the fastening screw located opposite the front of the arcing chamber arranged, and the claw-like extension on the quench chamber cover is positioned so that when the extinguishing chamber cover is put on the nose-like projection on the arcing chamber housing includes.
- the arcing chamber it proves to be particularly advantageous that the housing the quenching chamber and the quenching chamber cover with only one Screw are fastened together on the circuit breaker.
- the quench chamber cover is advantageous axially to the stop hole a through hole for inserting a tool for manipulating the fastening screw.
- the stop hole in the fire chamber cover can also be used as Through hole with constant diameter his.
- the proposed embodiments of the attachment of the Extinguishing chamber covers not only allow the number of total required fasteners and fasteners for Assembling the quenching chamber (for connecting the quenching chamber cover with the extinguishing chamber housing) by the one intended for fastening the complete arcing chamber Screw at the same time to connect the extinguishing chamber cover is used with the extinguishing chamber housing, it also ensures that the requirements are met regarding the sealing of the technically required gaps and joints against the passage of ionized arc gases, by positive locking elements that cover the arcing chamber support when switching against the gas pressure, a passage counteract these gases. This version allows both easier handling, as well as better sealing at the junction.
- FIG. 1 shows schematically a section through an inventive Fire chamber, according to a first variant.
- FIG. 2 shows schematically a section along the line A-B in Figure 3 by an arcing chamber according to the invention, according to a second variant.
- FIG 3 shows a view of the arcing chamber according to FIG the side where it is attached to the circuit breaker.
- the arcing chamber housing shown for example in Figure 1 1 points to the side 2 on which it is on the circuit breaker is attached, a hollow extension 3 in which a hole 4 for receiving the mounting screw 5 is located.
- On the opposite front side is 6 a horizontal one at the upper edge 7 of the arcing chamber housing 1 nose-like projection 8 arranged such that a claw-like Extension 9 of the extinguishing chamber cover 10 includes this if the quench chamber cover 10 is on the quench chamber housing 1 put on and moved along the edge 7.
- the fixation of the quench chamber cover 10 on the Extinguishing chamber housing 1 is made using only one fastening screw 5 through the hole 4 in the arcing chamber housing 1 passed and in a corresponding in the circuit breaker intended thread, not shown, is screwed in.
- the head 20 of this fastening screw 5 serves in a stop bore 22 for horizontal locking of the extinguishing chamber cover 10.
- There is an additional one angular element 19 provided in the form of a Washer held by the mounting screw 5 is and instead of the screw head 20 a stop for the Wall 21a in the stop bore 22 in the hollow extension 3 of the extinguishing chamber cover. If the screw head 20 form the stop itself, the extinguishing chamber housing receives 1 a wall 21, which is indicated by dash-dotted lines in FIG is.
- a through hole 23 is provided in the quench chamber cover 10 in the quench chamber cover 10 is axially to the stop bore Introduction of a tool for manipulating the fastening screw.
- the advantages of the fastening designs according to the invention of the fire chamber cover are not only in the small number of the total required connection and Fasteners for assembling the extinguishing chamber (for Connection of the extinguishing chamber cover to the extinguishing chamber housing), by attaching the entire extinguishing chamber provided screw at the same time for connecting the arcing chamber cover is used with the extinguishing chamber housing, but also in fulfilling the demands regarding the Sealing the technically required gaps and joints against the passage of ionized arc gases by Positive locking elements against the fire chamber cover when switching against support the gas pressure and counteract the passage of these gases.
