The present invention relates to an arc pressure trip device of a circuit breaker for improving the short circuit breaking performance.

도 1 내지 도 3 은 종래 기술의 배선용 차단기를 도시한 것으로서,1 to 3 show a circuit breaker of the prior art,

종래의 배선용 차단기의 개폐기구부는 차단기가 통전상태에서 사고전류가 발생되면 가동접촉자(2)와 고정접촉자 사이에 아크가 발생하여 아크배기구를 통해 배출되고, 도 1의 가동접촉자(2)가 통과하는 전류에 의해 반발되어 도 2와 같이 가동접촉자(2)가 회전하여 이동하고, 이때 가동접촉자(2)가 회전할 때 콘택트스프링(3)이 인장되어 충전됨과 동시에 도 1의 트립 기구부에서 사고전류에 대해 전자력을 일으키는 고정코어(5)의 흡인력에 의해 가동코어(4)가 고정코어(5) 위치로 이동하여 트립샤프트(6)를 회전시키고, 상기 트립샤프트(6)의 회전력에 의해 트립래치 리시버(7)가 풀려 리셋레버(8)를 구동하여 트립레치(9)가 풀리면서 인장되어 있던 오퍼레이팅 스프링의 압축되는 힘과 크로스바(1)에 조립되어 접점 반발력에 의해 인장된 콘텍트스프링(3)의 압축하는 힘이 합해져서 고속으로 도 2와같이 크로스바(1)를 회동시켜서 가동접촉자(2)와 고정접촉자간의 개극거리를 멀리하여 아크전압을 회복시키게 된다.In the case of a conventional circuit breaker, the opening and closing mechanism of the circuit breaker when an accident current is generated when the circuit breaker is energized, an arc is generated between the movable contactor 2 and the fixed contactor and discharged through the arc exhaust mechanism, and the movable contactor 2 of FIG. When the movable contactor 2 rotates and moves as shown in FIG. 2 and the movable contactor 2 rotates as shown in FIG. 2, the contact spring 3 is tensioned and charged, and at the same time, the tripping mechanism of FIG. The movable core 4 moves to the position of the fixed core 5 by the suction force of the fixed core 5 which generates an electromagnetic force, and rotates the trip shaft 6, and the trip latch receiver is driven by the rotational force of the trip shaft 6. (7) is loosened to drive the reset lever (8) to release the trip latch (9) of the contact spring (3) assembled by the compression force of the operating spring that has been tensioned and the crossbar (1) and tensioned by the contact repulsion forceCongratulations to thereby force the sum haejyeoseo by rotating the bar (1) as shown in Figure 2 at a high speed by a dog geukgeori between the movable contactor 2 and the fixed contact away recovering the arc voltage.

그러나, 종래의 기술은 배선용 차단기 내로 단락전류가 통과할 때 여러 단계를 거쳐 개폐기구부를 트립시키기 때문에 접점부에 머물고 있는 아크 플라즈마를 소호하는 시간이 오래 걸리고, 또한 차단기 에너지가 상대적으로 커져서 배선용차단기의 접점부가 융착되거나 융단되어 차단성능이 떨어지게되는 문제점이 발생하고 있었다.However, the conventional technique takes a long time to extinguish the arc plasma staying in the contact portion because the circuit breaker trips through several stages when a short circuit current passes into the circuit breaker, and the breaker energy is relatively large so that the circuit breaker is relatively large. There was a problem in that the contact performance is fused or fused to reduce the blocking performance.

따라서, 상기 문제점을 해결하기 위한 본 발명은 단락전류 인가시 고정접촉자와 가동접촉자의 접점 반발에 의해 발생한 고압의 아크가스(Arc gas)를 이용하여 단시간내에 여러단계를 거치지 않고 차단기의 리셋레버를 트립 동작시켜 고정접촉자와 가동접촉자가 분리되도록 하므로서, 단락전류 인가시 고정접촉자와 가동접촉자의 접촉부위에서 발생하는 아크 플라즈마(Arc Plasma)를 접점개폐부에서 빠른 시간내에 소호시키고, 전차단시간을 줄여서 차단기의 단락차단 성능을 향상시킬 수 있도록 한 배선용 차단기의 아크압력 트립장치를 제공함을 목적으로 한다.Therefore, in order to solve the above problems, the reset lever of the circuit breaker is tripped without using several steps within a short time by using a high-pressure arc gas generated by the contact reaction between the fixed contactor and the movable contactor when a short circuit current is applied. By operating to separate the fixed contactor and the movable contactor, when arc current is applied, arc plasma generated at the contact area of the fixed contactor and the movable contactor is quickly extinguished at the contact opening and closing part, and the short circuit breaker is shortened by reducing the electric breaker time. It is an object of the present invention to provide an arc pressure trip device for a circuit breaker to improve performance.

베이스(12)와 커버(10)의 결합에 의해 케이스를 이루고, 상기 베이스(12)와 커버(10)에는 아크배출구(16)를 통해 아크압력이 유입되는 아크압력유입구(11)를 형성하며, 케이스의 상단부에는 아크압력 유입구(11)를 통해 유입된 고압의 아크압력에 의해 회전하여 리셋레버(8)를 타격하여 리셋레버(8)가 트립래치(9)를 작동시킬 수 있도록 하는 트립레버(13)를 형성한다.The base 12 and the cover 10 form a case, and the base 12 and the cover 10 form an arc pressure inlet 11 through which arc pressure flows through the arc outlet 16. The upper part of the case is rotated by the high pressure arc pressure introduced through the arc pressure inlet 11 to hit the reset lever 8 so that the reset lever 8 can operate the trip latch 9 ( 13).

그리고, 상기 아크압력 트립부재(20)의 케이스 하단에는 각각 상에서 발생하는 아크가 케이스 내부로 유입되어 서로 통전되지 않게 절연시켜주는 절연 베리어(15)를 형성하고, 상기 트립레버(13)에는 트립레버(13)가 작동 후 원위치로 복귀하도록 하는 스프링(14)을 형성한다.The arc pressure tripping member 20 has an insulating barrier 15 formed at each of the lower ends of the arc pressure trip member 20 to insulate the arc generated from each case into the case so as not to be energized with each other, and a trip lever 13 at the trip lever 13. A spring 14 is formed which causes 13 to return to its original position after operation.

또한, 상기 트립레버(13)가 장착되는 베이스(12)와 커버(10)는 단락차단시 유입된 아크압력이 주변으로 세지 않도록 억지끼움 형태의 돌출 결합구조를 갖도록 하는 것이 바람직하다.In addition, it is preferable that the base 12 and the cover 10 on which the trip lever 13 is mounted have a protruding coupling structure in the form of interference fit so that arc pressure introduced during a short circuit is not counted around.

이와같이 구성된 본 발명의 동작을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.

평상시 고정접촉자와 가동접촉자(2)는 도 5 와 같이 접촉된 상태를 유지하며, 단락전류가 인가되면 상기 접촉부위에서 아크가 발생하여 아크배기구를 통해 배출됨과 동시에 가동접촉자(2)가 가동접촉자(2)에 통과하는 전류에 의해 반발되어 앞서 설명한 바와같이 회전하여 이동하고, 상기 가동접촉자(2)가 회전할 때 콘택트스프링(3)이 인장되어 충전된다.Normally, the fixed contactor and the movable contactor 2 remain in contact with each other as shown in FIG. 5, and when a short circuit current is applied, an arc is generated at the contact portion and is discharged through the arc exhaust outlet, and at the same time, the movable contactor 2 is movable contactor 2. Repulsed by the current passing through), rotates and moves as described above, and the contact spring 3 is tensioned and charged when the movable contactor 2 rotates.

이때, 본 발명에서는 아크압력이 아크배출구(16)를 통해 배출되고, 배출된 아크압력은 아크압력 트립부재(20)의 커버(10)와 베이스(12)에 형성된 아크압력 유입구(11)를 통해 아크압력 트립부재(20) 내부로 공급된다.At this time, in the present invention, the arc pressure is discharged through the arc discharge port 16, the discharged arc pressure is through the arc pressure inlet 11 formed in the cover 10 and the base 12 of the arc pressure trip member 20. The arc pressure trip member 20 is supplied into the interior.

아크압력 트립부재(20) 내부로 유입된 아크압력은 신속하게 상측으로 유동되어 스프링(14)을 수축시키면서 트립레버(13)를 반시계방향으로 회전시키게되고, 이에의해 트립레버(13)가 차단기에 설치되어 있는 리셋레버(8)를 타격하므로서, 리셋레버(8)가 트립래치(9)를 작동시켜 인장되어 있던 오퍼레이팅 스프링의 압축되는 힘과 크로스바(1)에 조립되어 접점 반발력에 의해 인장된 콘텍트스프링(3)의 압축하는 힘이 합해져서 고속으로 크로스바(1)가 회동하게되면서 가동접촉자(2)와 고정접촉자간의 개극거리를 멀리하여 아크전압을 회복시켜 단락사고에 의한 회로 보호차단을 완료하게 된다.The arc pressure introduced into the arc pressure trip member 20 quickly flows upward to rotate the trip lever 13 counterclockwise while contracting the spring 14, whereby the trip lever 13 is a breaker. By hitting the reset lever 8 installed in the reset lever 8, the reset lever 8 is operated by the trip latch 9, and is assembled to the crossbar 1 by the compression force of the operating spring that has been tensioned and tensioned by the contact repulsion force. As the compression force of the contact spring 3 is combined, the crossbar 1 rotates at a high speed, and the arc voltage is restored by separating the opening distance between the movable contactor 2 and the fixed contactor to complete the circuit protection interruption due to a short circuit accident. Done.

상기 동작시 절연베리어(15)는 각각 상에서 발생하는 아크가 케이스 내부로 유입되어 서로 통전되지 않게 절연시켜 준다.In this operation, the insulating barrier 15 insulates the arcs generated on each of the casings from flowing into the case so as not to be energized with each other.

이상에서 설명한 바와같이 본 발명은 단락전류 인가시 고정접촉자와 가동접 촉자의 접점 반발에 의해 발생한 고압의 아크가스를 이용하여 단시간내에 여러단계를 거치지 않고 차단기의 리셋레버를 트립 동작시켜 고정접촉자와 가동접촉자가 분리한 것으로, 이를 통해 단락전류 인가시 고정접촉자와 가동접촉자의 접촉부위에서 발생하는 아크 플라즈마를 접점개폐부에서 빠른 시간내에 소호시키고, 전차단시간을 줄여서 차단기의 단락차단 성능을 향상시킬 수 있도록 한 배선용 차단기의 아크압력 트립장치를 제공하는 효과를 기대할 수 있다.As described above, the present invention uses a high-pressure arc gas generated by the contact repulsion of the fixed contactor and the movable contactor when a short circuit current is applied to operate the fixed contactor by tripping the reset lever of the breaker without going through several steps within a short time. The contactor is separated, so that the arc plasma generated at the contact area of the fixed contactor and the movable contactor can be extinguished quickly at the contact opening and closing part when short-circuit current is applied, and the short circuit breaker time can be reduced to improve the short circuit breaker performance. The effect of providing the arc pressure trip device of the breaker can be expected.
