Abstract
The utility model relates to a zero arcover arc extinguishing device for a plastic casing breaker, which is characterized in that the zero arcover arc extinguishing device is composed of dissociation eliminating and arc extinguishing grid pieces [4], [5], a plurality of U-shaped arc extinguishing grid pieces [3] which are ranged in a radial mode, an end tab [2] and a partition board [1], wherein the end tab and the partition board are separated at intervals, the dissociation eliminating grid pieces are provided with a plurality of holes which are arranged by certain distances, and the arc extinguishing performance is directly or indirectly influenced by the thickness of the tab and the board, the size of the diameters of the holes, the thickness and the number of the dissociation eliminating grid pieces, the length of the distance and the adopted materials. The utility model has the advantages that the arc extinguishing performance can be effectively improved and the product safety can be enhanced under the condition of no change of the size of an original arc extinguishing chamber.
Description
The utility model relates to a kind of zero arcing arc-control device of mold cased circuit breaker, belongs to the low-voltage circuit breaker technical field.
Breaker of plastic casing is by plastic casing, operating mechanism, contact system, and arc-control device and tripping mechanism are formed, and at the outside arc-control device of placing of contact system, i.e. grid sheet arc extinguishing after deliberation, test, improve, installs several additional and removes free arc extinguishing grid pieces in the arc-control device outer end.As Chinese patent: the arc-control device of breaker of plastic casing (patent No. is 95243814.3), this circuit breaker remove free arc extinguishing grid pieces, make by the magnetic material thin plate, on thin plate, be equipped with several apertures, press the certain distance stack between plate and the plate, had and gone the arc-control device of free arc extinguishing grid pieces can quicken arc extinction, and prevention arc reignition, but owing to outside Switch main body, install free arc extinguishing grid pieces additional, making it volume of switch increases, need be improved, for another example Chinese patent: a kind of zero arcing arc control device of mold cased circuit breaker (patent No. is 97235207.4), the interrupter cartridge of this circuit breaker have been equipped with and have removed free grid sheet, reached simultaneously and gone free grid sheet and arc control device to unite two into one, but the more original arc-control device of volume is big by 1/3, moves after making the switch knob position, also need be improved.
The utility model provides a kind of zero arcing arc-control device of breaker of plastic casing, be under the situation of original arc control device constancy of volume, to go free grid sheet and arc-extinguish chamber to unite two into one, simultaneously run-on tab is placed on the arc-control device, this arc-control device is simple and practical, and limiting electric arc ejection Switch main body effectively, to make it flashover distance outward be zero.
For achieving the above object, the zero arcing arc-control device of breaker of plastic casing of the present utility model has following formation.It is mainly by arc-control device dividing plate, run-on tab, " U " type arc extinguishing grid pieces and go free arc extinguishing grid pieces to form, but it is different from prior art is that top and rear end in arc-control device installs free arc extinguishing grid pieces additional, thereby free grid sheet and arc-extinguish chamber are united two into one, simultaneously, go free arc extinguishing grid pieces to form by magnetic material, and structurally installed additional go the free arc extinguishing grid pieces by three and more multi-disc parallel longitudinal arrangement.So more help free arc extinguishing grid pieces repeated segmentation electric arc, improve arc voltage and quick extinguish arcs.
More excellent is, what installed additional in the described zero arcing arc-control device removes free arc extinguishing grid pieces, and the hole is interlaced between its sheet and the sheet.Being crisscross arranged between this film perforation helps the repeated segmentation of electric arc, improves arc voltage rapidly and quick extinguish arcs.
More excellent is, in the described zero arcing arc-control device, the THICKNESS CONTROL of removing free arc extinguishing grid pieces that is installed additional is at 0.5mm～1.5mm, and the aperture is controlled at φ 0.5mm～φ 2.5mm, pitch-row control 1mm～5mm.The effect of this set is comparatively desirable.
The utility model is described in further detail below in conjunction with accompanying drawing and example.
Fig. 1 is the utility model zero arcing arc-control device overall structure schematic diagram.
Fig. 2 is the utility model zero arcing arc-control device profile.
Fig. 3 removes free grid chip architecture schematic diagram for the utility model zero arcing arc-control device.
Fig. 4 is the utility model zero arcing arc-control device, and electric arc is at the motion diagram that goes to free grid sheet place.
With reference to Fig. 1～Fig. 4, (1), (6) are the arc-control device dividing plate, and (2) are run-on tab, (3) be " U " type arc extinguishing grid pieces, it is reflection-type arranges, and (4) remove free grid sheet for the top, (5a), (5b), (5c) be zero arcing arc-control device end of incoming cables and remove the grid sheet that dissociates.
The novel zero arcing arc-control device volume of this preferred embodiment is little, with the arc-control device equal volume of former breaker of plastic casing.It has installed additional at arc-control device rear end and top and has gone to free grid sheet (5a), (5b), (5c), (4), to lead arc plate (2) directly is placed on the arc-control device, go to free grid sheet (5a), (5b), (5c), (4) to select magnetic material for use, THICKNESS CONTROL is at 0.5mm～1.5mm, the aperture is controlled at φ 0.5mm～φ 2.5mm, and distance is at 1mm～5mm between the Kong Yukong; Remove free grid sheet (5a), (5b), (5c) spacing control 1～5mm, press the needs of product, the distance between plate thickness, pore size, the Kong Yukong, the distance between plate and the plate respectively has different.Owing to adopt this kind arc-control device, making the breaker of plastic casing flashover distance is zero, has improved security reliability.
In the utility model, when closing branch, switch produces electric arc, by run-on tab electric arc is imported in " U " arc extinguishing grid pieces (3), electric arc is divided into the short arc of many series connection, outwards spray, when arc spraying is divided into many short arcs again when removing free grid sheet (5a), after going free grid sheet (5b) to locate to be obstructed, detour and outwards spray, electric arc is divided into many short arcs once more; When arriving, electric arc goes free grid sheet (5c) to locate electric arc to be obstructed once more to detour and to enter outside injection, be divided into many short arcs again, thereby arc voltage is improved again and again, reach quick extinguish arcs, reach the design (see figure 4) of zero arcing; Run into free grid sheet (4) when electric arc upwards sprays, electric arc is divided into many strands of short arcs, makes it arc voltage and improves, and electric arc is extinguished fast, thereby reduces the scaling loss to switch cover.
Because adopt this novel zero arcing arc-control device, breaker of plastic casing not only arc extinction performance makes moderate progress, and flashover distance is zero, thereby makes the security performance and the technical performance raising of breaker of plastic casing.Simultaneously, volume of switch is remained unchanged.
