Abstract
The utility model relates to an arc extinguish device, which is especially suitable for electrical appliance elements with contacts in a low voltage which have a greater disconnecting ability. The structure of the utility model is characterized in that deionization nets which have equal spacing distances are fixedly installed in a cover casing and then are fixed by clamping plates. The utility model satisfies the requirements of a small size and high breaking development which the design of low voltage complete equipment fellows towards in recent years. The utility model can neutralize free gas in electric arc and thoroughly cool high-temperature gas, which solves an arc spraying phenomenon, effectively prevents a short circuit from occuring and avoids a fire accident and a human body damaging accident.
Description
The utility model relates to a kind of free arc-control device that disappears, and particularly a kind of being used for low be pressed with the contact and have the free arc-control device that disappears on the electric elements of big connecting-disconnecting function.
In the technique known, the low electric elements that are pressed with the contact such as circuit breaker, contactor etc., have arcing phenomena to produce in use.Though in production specifications, stipulated flashover distance, in concrete the use, still also exist deficiency, when installing, the first flashover distance to be avoided, and therefore, make the switchboard in the electric elements loosely organized; It two is low-voltage electrical apparatuses when cut-offfing big electric current, between the dynamic and static energy of having opened, produce bigger electric arc, electric arc itself is high temperature not only, and include many charged ions, in case electric arc flies out outside the electric elements shell, touch the different conductor of current potential (as the support in the electric elements) and be short-circuited, adjacent in addition the two poles of the earth arc potential difference also can be short-circuited, so cause fire incident easily at once; Three to be that the design of low-voltage complete equipment in recent years becomes compact, volume is little and high breaking, as drawer-type switch cabinet, control cubicle etc., but makes charger element assembly space also become little like this, and is therefore incompatible with the low voltage component of present use for it.
The purpose of this utility model is to overcome the deficiency of known technology, and provide a kind of can reach extinguish arc flame and prevent short circuit be used for low be pressed with the contact and have the free arc-control device that disappears on the electric elements of big connecting-disconnecting function.
The purpose of this utility model is achieved in that the free arc-control device that disappears can be the 2-3 utmost point, and wherein the disappear structure of free arc-control device of a utmost point is, adopts clamp to be installed with 10-35 sheet that spacing distance the equates free net that disappears in the case.
Have on the case of the present utility model top and be used for the hole that connects with the electrical equipment main body.
The utility model has the advantages that: this device is loaded on the electric elements, can makes the switchboard compact conformation, and adapt to the needs that design is little to volume and high breaking develops of low-voltage complete equipment in recent years.In addition, this device can be with free gas neutralization in the electric arc, and high-temperature gas fully cooled off, having reached the probability that to wear of discharging the electrical equipment outside reduces, the minimum average B configuration resistance value raises, and therefore, has solved arcing phenomena, and prevented the short circuit generation effectively, avoided the accident of fire and injury human body.
The utility model has following accompanying drawing:
Fig. 1 is that the free arc-control device that disappears is used for structural representation on the short-circuiting device;
Fig. 2 is a perspective view of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
The utility model can be selected 2 utmost points for use according to used low voltage component, also can select 3 utmost points for use; Present embodiment is selected for use is that the 3 utmost points free arc-control device that disappears is used for circuit breaker; In addition, the free net that disappears in the utility model also can be optional in this 10-35 sheet, and it is 20 that present embodiment is selected the free net that disappears for use.
Operation principle of the present utility model is: when electric arc under electromagnetic action; fly out behind the circuit breaker; enter the free arc-control device that disappears; disappear behind the free net through wherein multilayer, the ion in the electric arc is absorbed gradually again, and high temperature also descends gradually; therefore after filtering through electric arc; what the discharge circuit breaker was outer is the gas that thermal conductivity reduces greatly, conductivity is extremely low, can not cause the generation of short circuit, thereby play a protective role effectively.The utility model is particularly useful for hanging down and is pressed with the contact and has more obvious than effect on the electric elements of big connecting-disconnecting function.
Claims (2)
1, a kind of free arc-control device that disappears, form by case, the free net that disappears, clamp, it is characterized in that: the free arc-control device that disappears can be the 2-3 utmost point, and wherein the disappear structure of free arc-control device of a utmost point is, adopts clamps 6 to be installed with 10-35 sheet that spacing distance the equates free net 5 that disappears in the case 2.
2, the free arc-control device that disappears according to claim 1 is characterized in that: have on the case top and be used for the hole 7 that connects with the electrical equipment main body.
