Abstract
The invention relates to an arc-extinction device of a low voltage intelligent universal circuit breaker. The arc-extinction device of the low voltage intelligent universal circuit breaker is characterized by comprising arc-extinction railing pieces. The height of each arc-extinction railing piece is increased by 9mm-11mm. According to the arc-extinction device of the low voltage intelligent universal circuit breaker, appearance of each railing piece is designed optimally. Ends, close to a contact, of the 14 railing pieces extend outside by 10mm. An arc can be absorbed into an arc-extinction chamber thoroughly so that reasonable arrangement of components in all devices, including an arc striking board, can be achieved to the maximum degree and space in the arc-extinction chamber can be used completely, and therefore arc-extinction effect of the low voltage intelligent universal circuit breaker is good.
Description
Technical field
The invention belongs to a kind of low-voltage circuit breaker, particularly relate to a kind of arc-control device of low-voltage intelligent universal circuit breaker.
Background technology
At present the low-voltage intelligent universal circuit breakers such as TW40-4000 type are required to promote the breaking capacity index, the larger generation arc of electric current is more.So require arc control device are improved.
Summary of the invention
The present invention provides a kind of arc-control device with low-voltage intelligent universal circuit breaker of good arc quenching effect for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: it includes the arc extinguishing grid pieces in the arc-control device, and the height of described arc extinguishing grid pieces has increased the 9-11 millimeter.
Advantage and good effect that the present invention has are: in limited space, optimal design grid sheet profile, 14 arc extinguishing grid pieces are stretched out 10mm near contact end, fully arc is drawn into arc control device, make the interior part of all devices that comprises run-on tab reach to greatest extent reasonable Arrangement, utilized fully the arc control device space, thereby made low-voltage intelligent universal circuit breaker have good arc quenching effect.
Description of drawings
Fig. 1 is general structure schematic diagram of the present invention;
Fig. 2 is several schematic diagrames of arc extinguishing grid pieces among Fig. 1.
Embodiment
For further understanding content of the present invention, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
As shown in Figure 1, arc-extinguishing chamber of circuit breaker insulation shell 2, the height that is installed in the arc extinguishing grid pieces 1 that the flat shape of housing inner chamber arranges has increased by 10 millimeters, is provided with five insulating barriers 3 and run-on tab 4 in the housing upper end.
As shown in Figure 2, the arc extinguishing grid pieces 1 of the outstanding external part of special design, parallel arrangement between sheet and the sheet is beneficial to attraction electric arc and enters arc control device, and arc extinguishing grid pieces 1 is parallel arrangement and takes full advantage of the arc control device space, the increase arc control device effective volume of the limit.Five insulating barriers 3 are arranging of angle, can reduce arcing in the arc extinguishing process, simultaneously arc extinguishing grid pieces 1 are played booster action, fully accomplish the minimizing arcing.
Claims (1)
1. the arc-control device of a low-voltage intelligent universal circuit breaker, it includes the arc extinguishing grid pieces in the arc-control device, it is characterized in that: the height of described arc extinguishing grid pieces has increased the 9-11 millimeter.
