Abstract
The utility model relates to a breaker arc extinguish chamber with an insulated clapboard, and a slot-shape space formed by the fork-shaped portion of a plurality of fork-shaped bar pieces in the arc extinguish chamber is installed with two insulated clapboards. An open passage is formed between the two insulated clapboard. The electric arc produced in breaking is led to the deeper place of the arc extinguish chamber by the passage, and the electric arc is elongated. Meanwhile, the electric arc is divided into a plurality of short arcs by the bar pieces. The contact area with the air is enlarged, and the cooling speed is increased, and the extinguishing of the arc is accelerated.
Description
The utility model relates to a kind of arc-extinction device of switch, particularly a kind of arc-extinguishing chamber of circuit breaker that is provided with insulating barrier.
In order to cool off, extinguish the electric arc that circuit breaker produces when breaking current, general circuit breaker is equipped with arc control device.The arc control device of breaker of plastic casing are to be fixed between the arc chamber sidewall of two sides a plurality of metal gate sheets are parallel, some arc control device grid sheet two side direction moving contact directions extension is fork-shaped, a plurality of grid sheets form the channel towards the moving contact opening in the share, divide the moving contact end of having no progeny to be positioned at this channel.Existing breaker of plastic casing is when breaking current, and the electric arc that is produced is divided into some short arcs by the metal gate sheet of arc control device, and the electric arc between dynamic/static contact is difficult for extinguishing, and interrupts, and arc quenching effect is not good, influences the timely disjunction of electric current.
The purpose of this utility model provides a kind of arc-extinguishing chamber of circuit breaker that is provided with insulating barrier, insulating barrier is installed in share at arc control device fork-shaped grid sheet, form the depth passage, the a large amount of electric arcs that produce when making breaking current are elongated and develop to the arc control device vertical-depth, like this, long arc and short arc exist simultaneously, improve the cooling of electric arc and extinguish speed, improve the arc quenching effect of circuit breaker.
For achieving the above object, the utility model is taked following design: at the channel place that the share of a plurality of fork-shaped grid of arc control device sheet forms 2 insulating barriers are installed, the outer rim of dividing plate is sandwiched between the arc chamber sidewall and the grid sheet outside, its inner rim inserts in the interpolation slit that is positioned at channel on the grid sheet, forms the passage that opens wide between 2 dividing plates.
The utility model is provided with the arc-extinguishing chamber of circuit breaker of insulating barrier, insulating barrier is installed at the channel place that forms in each grid sheet share, form comparatively narrow passage shape by dividing plate, the vertical-depth of the electric arc guiding arc control device that produce during with disjunction, electric arc is elongated by integral body, in being elongated process, be divided into the plurality of sections short arc by the grid sheet again, strengthened and the air contact area, improved cooling rate, shortened the arc extinction time, thereby improved the arc quenching effect of circuit breaker, the timely disjunction of favourable electric current.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the bottom view of the utility model arc control device
Fig. 2 is the side cut-away view of this arc-extinguishing chamber of circuit breaker
As shown in Figure 1 and Figure 2, the utility model is provided with the arc-extinguishing chamber of circuit breaker of insulating barrier, at the channel place that the share 6 of a plurality of fork-shaped grid of arc control device sheet 2 forms 2 insulating barriers 4,5 are installed, the outer rim of dividing plate is sandwiched between the arc chamber sidewall 1 and the grid sheet outside, inner edge inserts in and forms the passage that opens wide between 3,2 dividing plates of interpolation slit that are positioned at channel on the grid sheet.Fig. 2 is Figure 1A-A place rotation cut-away view, can see the position of moving contact 7 in the channel of arc control device, has also showed the state of insulating barrier 4 barrier grid sheets 2 shares.Arrow is depicted as the electric Arc Motion direction among the figure.As embodiment of the present utility model, described insulating barrier adopts Nuo Mikesi insulating paper (Nomex) manufacturing, when arcing is on this material, because the effect of high arc temperature produces inert gas, these inert gases produce electric arc and go free and cooling effect, further quicken extinguishing of electric arc, improve arc quenching effect.
Claims (2)
1, a kind of arc-extinguishing chamber of circuit breaker that is provided with insulating barrier, it is characterized in that: 2 insulating barriers are installed at the channel place that the share of a plurality of fork-shaped grid of arc control device sheet forms, the outer rim of dividing plate is sandwiched between the arc chamber sidewall and the grid sheet outside, its inner rim inserts in the interpolation slit that is positioned at channel on the grid sheet, forms the passage that opens wide between 2 dividing plates.
2, the arc-extinguishing chamber of circuit breaker that is provided with insulating barrier according to claim 1 is characterized in that: described insulating barrier adopts the manufacturing of Nuo Mikesi insulating paper.
