Description

The arc control device that are used for circuit breaker with electric arc gas exhaust passage
Technical field
The present invention relates to be used for the arc control device of electric equipment, in particular for the arc control device of circuit breaker and other switchgears.
Background technology
In electric equipment, when interrupting short circuit, can form a large amount of electric arcs, this is ionized gas-plasma, it comprises cation and anion.Electric arc is feature with high current density, high temperature and a large amount of radiation in wide range.Electric arc destroys the material of contactant consumingly, makes this material melts and splash.Contactant may be destroyed, break etc., and this is to cause because formed this fact of big temperature gradient simultaneously on contactant.Therefore, be necessary to limit electric arc electric arc is also eliminated in the influence of contactant as early as possible.In order to drop to bottom line to the destruction of contactant, electric arc must be transferred to spark plate as early as possible, so electric arc must dynamically spread to the arc extinguishing board of arc control device.Is the key factor of eliminating electric arc by arc extinguishing board to the strong cooling of electric arc and the pressure condition in the arc control device.
From the angle of structure, for instance, known arc control device are to be assembled by two side plates with holes, and arc extinguishing board is inserted in the described side plate.Assembly is by rivet or screw or analog crosswise fixed.
In the assembling of another known structure, arc control device are made by two thermosetting moulded parts (thermosetting molding), promptly make by the base portion that is inserted by arc extinguishing board and by the fixing sealing cover of arc extinguishing board.This conception does not provide the possibility that is installed to filter and deionization element (deionizationelement) in the main body of arc control device and therefore pressure condition and technical effective condition are set efficiently, described pressure condition and technical effective condition influence are eliminated electric arc, also with relevant in the destruction of the plasma of plasma splash during the near zone of electric equipment.
Summary of the invention
Target is for producing a kind of arc control device that are used to eliminate electric arc and effectively influence the adjustable pressure condition of plasma splash that have when interrupting short circuit, and the arc control device that produce a kind of modularization assembling, it does not use additional Connection Element, the unnecessary otherwise fastening possible diffusion that prevents of formed firm assembly, and given target is achieved by utilizing solution of the present invention, essence of the present invention is, arc control device are made up of a dimeric casing, described casing comprises the shell that has arc extinguishing board and spark plate, the sealing cover that has discharge duct is fastened to the side of shell, beginning part at discharge duct, interface place at dimeric casing, produce circumference groove (perimetral notch), be used to insert at least one technical arbitrarily effectively filler with holes.
According to the present invention, do not use additional insert, and the cross wall that will when making sealing cover, produce, form for example perforation of filter cell technically to be placed on the front of the circumference groove in the discharge duct be favourable.
According to the present invention, for will be arbitrarily technical effective element reliable and firm be placed into discharge duct, the circumference groove produces in sealing cover and comprises the buffering suface and the guided outside ledge surperficial and at least one braking that are used for above-mentioned at least one filler is favourable.
The explanation of figure in the accompanying drawing
More advantage of the present invention and effect are apparent because of accompanying drawing, wherein Fig. 1 is the vertical centre profile of the dimeric casing of arc control device, the all elements that are included in the casing have all been made mark, comprise the alternative filler in the circumference groove of the discharge duct that is installed in the arc control device sealing cover, Fig. 2 is the view of the arc control device under the decomposing state of watching from certain angle.
Inventive embodiment
Be used for electric equipment, arc control device 1 especially for circuit breaker, be inserted into the hollow space of the electric equipment base portion that does not illustrate, and the arc extinguishing board 2 by one group of trapezoidal arrangement and spark plate 3 surround the track of path of end of the movably contactant of the electric equipment that does not illustrate.
Arc control device 1 (Fig. 1) are made up of a dimeric casing, and described dimeric casing is made up of shell 4 that has arc extinguishing board 2 and spark plate 3 and the sealing cover that has discharge duct 65 that is assembled to shell 4 securely.
Beginning at discharge duct 6 is partly located, in the interface of dimeric casing, circumference groove 7 is produced is used to insert at least one technical arbitrarily effective filler 8, for example the filter cell 9 and/or deionization element 10 (Fig. 2) in suitable hole is arranged.Filler 8 can have different structures, and can make or have a grid that magnetic metal forms by nonmagnetic substance, or similar structure, comprise various perforation configurations.Concerning given electric equipment, by effective combination to filler 8 purposes, and it is final by displacement to these fillers, the pressure condition of the expectation in the arc control device 1 might be set effectively, and when interrupting short circuit, selectively not only eliminated by harmful external effect of the plasma of the electric arc in eliminating in arc control device 1 inside but also in the exit of discharge duct 6.
According to embodiment, circumference groove 7 (Fig. 2) produces in the sealing cover 5 of dimeric casing, and circumference groove 7 comprises the buffering suface 11 that is used for filler 8, guided outside surface 12 and prevents filler 8 or the ledge 13 of at least one braking that filler male part 8 comes off naturally from circumference groove 7.In some cases, the perforation cross wall that does not illustrate can replace the buffering suface 11 in the discharge duct 6, the perforation cross wall is placed on the front of circumference groove 7, produces for example filter element 9 in perforation cross wall self, directly produces in the production of described perforation cross wall during sealing cover 5 is made.
Arc control device 1 are designed to the dimeric casing that formed by the thermosetting moulded parts, simultaneously shell 4 in for inserting arc extinguishing board 2 and spark plate 3 establishment guide lips (guide rib) 14.The sealing cover 5 of arc control device 1 is fastening with anti-loose with arc extinguishing board 2 and spark plate 3, and inside cutting ferrule (collar) 15 by sealing cover 5 keep arc extinguishing board 2 and spark plate 3 in position, and cutting ferrule 15 also seals the dimeric casing of arc control device 1 in case steam is diffused into the immediate area of the hollow space of electric equipment from arc control device 1.Inner cutting ferrule 15 can be equipped with various other ledges, and for example ledge 16, is used to make spark plate 3 brakings of top etc.Sealing cover 5 is and control gaseous is passed filter cell 9 and/or deionization element 10 is blown into discharge duct 6.The structure of arc control device 1 does not contain the use to filter cell 9 and deionization element 10.Even do not use any of these various technical effective fillers 8, arc control device 1 also work.
In the front side of the shell 4 of arc control device 1, there is the inspection hole opening 17 of the movably contactant that is used for unshowned electric equipment.
