Abstract
The utility model relates to a circuit breaker, including casing and operating device, dropout system, arc -extinguish chamber, the binding post of setting in the casing, the casing forms in binding post below and lets out the nock, and the rear end of the inherent arc -extinguish chamber of casing forms lets out the arc passageway, lets out the arc passageway and lets out the nock and is connected, lets out nock inboard equidistance and is provided with the multi -disc and lets out the arc piece, lets out and forms a plurality of arc holes of letting out on the arc piece, lets out for adjacent two and lets out that the arc hole is corresponding to be had a perfect understanding on the arc piece. The utility model discloses the arc piece is let out in the setting, and the adjacent arc hole of letting out of letting out on the arc piece does not correspond and has a perfect understanding, can stop when letting out the arc that high -temperature gas is direct to discharge, reduces high -temperature gas's exhaust velocity and distance, and high -temperature gas can not be hindered to outside electric wire, improves life.
Description
Technical field
This utility model relates to a kind of chopper.
Background technology
Chopper generally arranges at arc-extinguish chamber rear and lets out nock, high temperature gas flow after arc extinguishing is discharged by letting out nock, existing chopper is letting out usually not other coverages in nock, when high temperature gas flow is discharged, high temperature gas flow can directly be flushed to outside chopper, high-temperature gas is sprayed onto people's cognition and causes certain injury, especially the wire being exactly to be connected with binding post is let out outside nock, wire is sprayed onto by high temperature gas flow can cause that wire is aging, affect the life-span of wire and then cause the accidents such as wire electric leakage, there is bigger potential safety hazard.
Summary of the invention
For above-mentioned reasons, this utility model provides a kind of arc extinguishing ability strong, lets out arc safety, the chopper of long service life.
For achieving the above object, this utility model adopts a kind of chopper, including housing and be arranged on the operating mechanism in housing, tripping system, arc-extinguish chamber, binding post, described housing lets out nock binding post is formed below, the rear end of housing inherence arc-extinguish chamber is formed and lets out arc passage, lets out arc passage and is connected with letting out nock, lets out and has been placed equidistant multi-disc inside nock and lets out arc sheet, let out and arc sheet formed multiple arc hole of letting out, adjacent two panels let out on arc sheet to let out arc hole not corresponding through.
This utility model is further arranged to described multi-disc and lets out arc sheet and linked into an integrated entity by arc connecting portion.
This utility model is let out arc passage and is divided into three roads lets out arc groove by letting out arc dividing plate described in being further arranged to.
This utility model is let out nock and is let out with three that arc groove is corresponding is divided into three described in being further arranged to.
Arc sheet is let out in the setting in arc passage of letting out that the beneficial effects of the utility model are at arc-extinguish chamber rear, adjacent let out on arc sheet to let out arc hole not corresponding through, can stop that when letting out arc high-temperature gas is expelled directly out, reduce the velocity of discharge and the distance of high-temperature gas, allow high-temperature gas can not hurt external cable, improve service life.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this utility model specific embodiment.
Fig. 2 is the schematic diagram letting out arc sheet in this utility model specific embodiment.
Detailed description of the invention
Such as Fig. 1, shown in Fig. 2, specific embodiment of the utility model is a kind of chopper, including housing 1 and be arranged on the operating mechanism 3 in housing 1, tripping system 4, arc-extinguish chamber 5, binding post 6, housing 1 lets out nock 11 binding post is formed below, the rear end of the inherent arc-extinguish chamber 5 of housing 1 is formed lets out arc passage 12, let out arc passage 12 and let out nock 11 and be connected, let out arc passage 12 to be divided into three roads let out arc groove 14 by letting out arc dividing plate 13, let out nock 11 and let out with three that arc groove 14 is corresponding is divided into three, let out and be placed equidistant inside nock 11 letting out arc sheet 2, let out arc sheet 2 to be bent to form 5 and let out cambered surface 21, let out cambered surface 21 is formed and multiple let out arc hole 22, adjacent two let out in cambered surface 21 to let out arc hole 22 not corresponding through.
