본 고안은 배선용 차단기에서 회로차단시 정류의 관성에 의해 접점간(5)에 발생하는 아크를 흥수, 분리, 냉각시키는 배선용 차단기의 소호장치에 관한 것이다.The present invention relates to a circuit breaker extinguishing device for submerging, separating, and cooling an arc generated between the contacts 5 due to the inertia of rectification in circuit breakers.

배선용 차단기에서 회로 차단을 할때 접점간(5)에 발생하는 아크는 아크의 전압과 전류의 적으로 많은 에너지를 수천도의 비상히 높은 온도에서 금속증기를 열전리하여 접점, 절연물등에 유해를 끼침으로 공지된 도면 제4(a)도, 제4(b)도에서보는 바와 같이 종래에는 그리드(2)라 불리는 V자형의 자성판을 적당한 간격으로 그리드 절연물 지지판(4)에 고정시킨 소호장치(가)를 차단기내의 접점부(5)옆에 설치하여 아크열 소호장치로서 사용하여 왔기 때문에(제3도참조) 제조원가의 상승은 물론 조립공정상에도 많은 시간을 요했던 것으로 제4(a)도는 전류의 관성에 의해 아크가 흡수되는 디 이온의 원리를 도시한 것이고, 제2(b)도는 상기한 제2(a)도의 원리를 이용흡수된 아크를 분리 냉각시키는 종래의 소호장치(가)의 조립된 상태도이다.When the circuit breaker is disconnected from the circuit breaker, the arc generated between the contacts (5) causes a lot of energy of the arc voltage and current to thermally ionize the metal vapor at an extremely high temperature of thousands of degrees, causing harm to the contacts and insulators. As shown in FIG. 4 (a) and FIG. 4 (b), a fire extinguishing device in which a V-shaped magnetic plate, which is conventionally referred to as a grid 2, is fixed to the grid insulator support plate 4 at appropriate intervals. ) Is installed next to the contact part 5 in the breaker and used as an arc heat extinguishing device (see Fig. 3). Therefore, it took much time not only to increase the manufacturing cost but also to the assembly process. Figure 2 shows the principle of di ions absorbed by the inertia, Figure 2 (b) is assembled of a conventional extinguishing device (a) to separate and cool the absorbed arc using the principle of Figure 2 (a) described above State diagram.

본 고안은 종래에 사용했던 그리도(2')와 절연물지지판(4)으로 이루어진 소호장치(가)를 설치하지않고 보다 간편하고 효율적인 제작을 할 수 있도록 안출한 것으로 첨부도면에 의거 상세히 설명하면 다음과 같다. 제1도에서 도시한 바와같이 엔지니어링 프라스틱으로 케이스(1)를 형성하되 케이스(1) 내측의 접점부(5) 일측으로 케이스(1)와 일체로 소호용 그리도(2)를 돌출 형성하고, 상기한 그리드(2) 표면과 케이스(1) 내측면에 내열페인트(3)를 도포하여서 되는 것이다.The present invention is designed to enable a simpler and more efficient production without installing the SOHO device (2) and the insulating support plate (4) used in the prior art as described in detail according to the accompanying drawings as follows. same. As shown in FIG. 1, the case 1 is formed of an engineering plastic, but the extinguishing grille 2 is integrally formed with the case 1 toward one side of the contact portion 5 inside the case 1, and The heat-resistant paint 3 is applied to the surface of one grid 2 and the inner surface of the case 1.

이와같이 구성된 본원 고안의 작용효과를 살펴보면, 종래의 소호장치(가)가 설치되었던곳에 소호장치(가)를 제거하고 제1도, 제2도에서 보는 바와같이 케이스(1)와 일체로 그리드(2)를 돌출형성하며, 상기한 그리드(2) 표면과 케이스(1)의 내측면에 내열페인트(3)를 도포하였기 때문에 배선용 차단기의 회로차단시 접점간(5)에서 발생하는 아크열은 돌출된 그리드(2)에 의하여 흡수·분리·냉각이 되며 동시에 케이스(1) 내측면 역시 내열페인트(3)로서 도포하였기 때문에 아크열에 견딜 수 있는 것이다. 즉, 케이스(1) 내측에 돌출된 그리드(2)가 소호역할을 소호장치인 것이다. 또한 케이스(1)의 재질로는 내열성이 강하고 기계적 강도가 강한 폴리에스터 계통의 엔지니어링 프라스틱을 사용하여 아크열에서도 케이스(1)가 충분히 견딜수 있도록 하였다. 상기와 같이 본원 고안을 종래와 같이 복잡한 소호장치를 별도로 부착사용하지 않고 직접 케이스(1)에 그리드(2)를 돌출 형성시켜 작업을 손쉽게 할 수 있음은 물론 경제성을 주는 고안인 것이다.Looking at the effect of the present invention configured as described above, remove the extinguishing device (a) where the conventional extinguishing device (a) was installed, and as shown in Figures 1 and 2, the grid (2) integrally with the case (1) ) And heat-resistant paint (3) is applied to the surface of the grid (2) and the inner surface of the case (1), the arc heat generated between the contacts (5) during the circuit breaker of the circuit breaker is projected It is absorbed, separated and cooled by the grid 2, and at the same time, the inner surface of the case 1 is also applied as the heat-resistant paint 3 so that it can withstand arc heat. In other words, the grid 2 protruding inside the case 1 serves as an arc extinguishing device. In addition, as the material of the case 1, the case 1 is sufficiently resistant to arc heat by using an engineering plastic of a polyester system having high heat resistance and strong mechanical strength. As described above, the present invention can be easily made by protruding the grid 2 directly into the case 1 without separately attaching a complicated arc extinguishing device as in the related art, as well as devising economic efficiency.
