Description
본 고안은 원자력 발전소나 기타 산업용 발전소 등에 설치된 대형 발전기(Generator)에 관한 것이다.The present invention relates to a large generator (generator) installed in nuclear power plants or other industrial power plants.
더욱 상세하게는, 발전기의 회전자에 설치되어 직류전원을 공급하는 브러쉬(Brush)와 탄력적으로 접촉하는 콜렉터링(Collector Ring)의 표면을 짧은 시간안에 깨끗하고 정밀하게 연마(Polishing)할수 있는 발전기의 콜렉터링 연마장치에 관한 것이다.More specifically, it is possible to clean and precisely polish the surface of the collector ring installed in the rotor of the generator in contact with the brush supplying the DC power in a short time. It relates to a collector ring polishing apparatus.
일반적으로 발전기는 크게 고정자와 회전자로 나뉘어지며, 계자역할을 하는 회전자에 직류전원을 공급하기 위하여 도체인 금속재의 콜렉터링과 브러쉬를 사용하게 된다.Generally, a generator is divided into a stator and a rotor, and a collector ring and a brush made of metal are used to supply DC power to the rotor serving as a field.
콜렉터링은 통상 회전자에 부싱(Bushing)형태로 끼워져 브러쉬매거진을 배열하는 리깅(Rigging)에 둘러싸여 있고, 브러쉬는 상기 리깅에 브러쉬매거진을 통하여 원형으로 배열되게 장착되므로서 콜터링의 표면과 접촉하게 된다.The collector ring is usually surrounded by a rigging that is inserted into the rotor in the form of a bushing and arranges the brush magazine, and the brush is mounted in a circular arrangement through the brush magazine in contact with the surface of the colleting ring. do.
이러한 브러쉬 타잎의 발전기는 정상적으로 운전하는 도중, 브러쉬의 재질상의 문제로 인해 콜렉터링의 표면에 마찰손상이 발생하고, 여름철에도 번개와 같은 외적요인에 의해 이상전압이 발생하게 된다.During the normal operation of the brush type generator, friction damage occurs on the surface of the collector ring due to a problem in the material of the brush, and an abnormal voltage occurs due to external factors such as lightning even in summer.
이 경우, 브러쉬와 콜렉터의 접촉면 사이에 이상전류가 흘러 풋트마크(Foot Mark)등이 찍히므로서 심한 불꽂이 발생하고 정상운전을 불가능하게 할 때가 많다.In this case, an abnormal current flows between the contact surface of the brush and the collector, causing a foot mark, etc., to cause a severe fire and often impossible to operate normally.
이러한 경우, 종래에는 도 6 내지 도 8에서 보는 바와 같이 발전기의 출력을 감발하여 리깅(20)에 둘러싸인 콜렉터링(10)의 속도를 약 1800RPM 내지 3600RPM 정도로 고속 회전시키면서 리깅에 장착된 브러쉬매거진(210)을 빼낸 다음, 다시 그 자리에 연마지(270)가 감긴 나무토막(260)을 삽입하여 손으로 눌러 나무토막의 연마지가 콜렉터링의 표면과 압착되도록 하므로서 콜렉터링의 표면이 연마지에 의해 연마되도록 하였던 것이다.In this case, the brush magazine 210 mounted on the rigging while rotating the speed of the collector ring 10 surrounded by the rigging 20 at a high speed by about 1800 RPM to 3600 RPM as shown in FIGS. ), And then, by inserting the wood chip 260 wound with the abrasive paper 270 in place and pressing it by hand, the surface of the collector ring is polished by the abrasive paper while the abrasive paper of the wood chip is pressed against the surface of the collector ring. It was.
그리고, 발전기의 출력과 회전이 정지된 상태에서는 콜렉터링(10)의 속도를 터닝기어의 스피드(Turning Gear Speed)인 약 3∼7RPM 정도로 저속 회전시키면서 상기 고속 회전시와 마찬가지로 연마지(270)가 감긴 나무토막(260)을 리깅(20)에 삽입하여 손으로 눌러 압착력을 가하므로서 콜렉터링의 표면이 연마되도록 하였던 것이다.In the state where the output and rotation of the generator are stopped, the abrasive paper 270 rotates at a low speed of about 3 to 7 RPM, which is the turning gear speed, of the turning gear 10. By inserting the rolled wood chips 260 into the rigging 20 by pressing the hand by pressing force to the surface of the collector ring was to be polished.
그런데, 상기와 같은 장치는 연마지(270)가 감긴 나무토막(260)을 이용하여 콜렉터링(10)의 표면을 연마하는 수작업인 관계로 불필요한 작업인원의 과다투입으로 인건비 상승을 야기시킬 뿐만 아니라 연마속도가 느려 많은 시간이 소요되는 단점이 있었다.However, such a device is a manual work of polishing the surface of the collector ring 10 by using the wood chips 260 on which the abrasive paper 270 is wound, thereby causing labor costs to be increased due to excessive input of unnecessary working personnel. There was a disadvantage that it takes a lot of time because of the slow grinding speed.
또한, 수작업인 관계로 연마지를 콜렉터링의 표면에 균일한 힘으로 압착하기가 힘들고, 이로 인해 양질의 표면(원주)을 얻기가 어려운 문제점이 있었다.In addition, it is difficult to press the abrasive paper with a uniform force on the surface of the collector ring because it is a manual work, and thus it is difficult to obtain a good surface (circumference).
본 고안은 이러한 문제점을 해결하기 위하여 안출한 것으로 그 기술적인 과제는 연마지가 감긴 브러쉬모형의 나무토막이나 연삭숫돌을 브러쉬매거진에 삽입한 후, 상기 브러쉬매거진을 리깅에 장착하면, 연마지가 콜렉터링의 표면에 항상 균일한 힘으로 압착되어 양질의 표면을 신속하고 정밀하게 얻을수 있는 연마장치를 제공함에 있다.The present invention has been made to solve the above problems, and the technical problem is that after inserting the brushed wood chips or grinding wheel into the brush magazine, and then mounting the brush magazine to the rigging, the abrasive paper is the collector ring. The present invention provides a polishing apparatus that is always pressed to the surface with uniform force to obtain a high quality surface quickly and precisely.

It is formed integrally with a fixture 190 for fixing the abrasive paper 170 is fitted thereto.
상기와 같이 구성된 본 고안의 동작 및 작용에 대하여 설명하면 다음과 같다.Referring to the operation and operation of the present invention configured as described above are as follows.
먼저, 브로쉬매거진(100)을 조립할때는 도 3 및 도 4와 같이 서포트아암(110)의 전면에 브러쉬홀더(120)를 볼트(114)로 체결하고, 관통홀(112)에 래치샤프트(130)를 삽입하여 그 상단에 손잡이(140)를 결합한다.First, when assembling the broth magazine 100, as shown in Figs. 3 and 4, the brush holder 120 is fastened to the front of the support arm 110 with a bolt 114, and the latch shaft 130 in the through hole 112. Insert and combine the handle 140 to the top.
이때, 볼트(114)는 장공(113)의 하단에 위치시킨다.At this time, the bolt 114 is located at the lower end of the long hole 113.
그리고, 브러쉬홀더(120)의 삽입홈(121)에 카본브러쉬(150)를 삽입한다.Then, the carbon brush 150 is inserted into the insertion groove 121 of the brush holder 120.
이렇게 조립된 브러쉬매거진(100)을 리깅(20)의 장착부에 삽입하면, 서포트아암(110)의 가이드부(111)가 장착부에 형성된 더브테일 형상의 가이드레일을 따라 삽입된다.When the brush magazine 100 assembled as described above is inserted into the mounting portion of the rigging 20, the guide portion 111 of the support arm 110 is inserted along the dovetail-shaped guide rail formed on the mounting portion.
또한, 삽입이 완료되는 순간 손잡이(140)를 90°회전시키면, 래치샤프트(130)의 걸림턱(132)이 리깅의 단턱에 걸려 브러쉬매거진의 이탈이 방지되도록 지지하게 되고, 작동핀(131)은 스토퍼(40)를 브러쉬홀더(120)의 저면부로 부터 멀어지게 하여 브러쉬가 콜렉터링에 접촉하게 된다.In addition, when the handle 140 is rotated by 90 ° when insertion is completed, the latching jaw 132 of the latch shaft 130 is caught on the step of the rigging to support the separation of the brush magazine, and the operation pin 131 is supported. The silver makes the stopper 40 away from the bottom of the brush holder 120 so that the brush contacts the collector ring.
이와 같은 상태에서 발전기가 작동하는 동안, 브러쉬홀더(120)에 삽입된 브러쉬(150)는 콜렉터링(10)과 접촉하면서 상기 콜렉터링에 직류전원을 공급하게 된다.While the generator is operating in this state, the brush 150 inserted into the brush holder 120 is in contact with the collector ring 10 to supply DC power to the collector ring.
또한, 발전기가 정상적으로 작동하는 도중, 브러쉬(150)가 갖고 있는 재질상의 이유나 여름철 번개 등에 의한 이상전류의 발생으로 콜렉터링(10)의 표면에 마찰손상 및 이상전압이 발생하면, 브러쉬와 콜렉터의 접촉면 사이에 이상전류가 흘러 풋트마크등이 찍히게 되고, 이로 인해 심한 불꽂이 발생하거나 정상운전이 불가능하게 된다.In addition, if the friction damage and the abnormal voltage are generated on the surface of the collector ring 10 due to the material reason of the brush 150 or the occurrence of an abnormal current caused by a summer lightning during the normal operation of the generator, the contact surface between the brush and the collector. An abnormal current flows between them, resulting in a foot mark, etc., which causes severe fire injuries or normal operation.
이때는, 브러쉬매거진(100)을 리깅(20)의 장착부에서 빼낸 뒤 각각의 브러쉬(150)를 분리시키고, 다시 그 자리에 연마지(170)가 감긴 브러쉬모형(160)을 삽입하면 된다.In this case, after removing the brush magazine 100 from the mounting portion of the rigging 20, each brush 150 is separated, and the brush model 160 wound around the abrasive paper 170 may be inserted therein.
상기 동작중, 브러쉬모형은 브러쉬에 비해 접촉면이 일체로 되어 있기 때문에 브러쉬홀더와 콜렉터링의 표면 보다 더 넓은 공간이 필요하다.During the above operation, the brush model requires a larger space than the surface of the brush holder and the collector ring because the contact surface is integral with the brush.
이때는, 공간을 충분히 확보할수 있게 제작된 서포트아암(110)으로 교체하여 브러쉬홀더에 조립하면 된다.In this case, the support arm 110 may be assembled to the brush holder by replacing it with the support arm 110, which is manufactured to ensure sufficient space.
이렇게 하면, 브러쉬홀더(120)가 콜렉터링과 충분한 공간을 유지할수 있게 된다.This allows the brush holder 120 to maintain the collector ring and sufficient space.
상기와 같이 브러쉬대신 브러쉬모형이 장착된 브러쉬매거진(100)을 리깅에 장착하면, 브러쉬모형의 저면에 감긴 연마지(170)가 스프링(180)의 탄성력을 받아 콜렉터링(10)의 표면과 탄력적으로 접촉하게 되므로서 콜렉터링의 표면에는 항상 균일한 압착력이 작용하게 되어 신속하고도 정밀하게 연마된다.When the brush magazine 100 having a brush model instead of a brush is mounted on the rigging as described above, the abrasive paper 170 wound on the bottom of the brush model receives elastic force of the spring 180 and is elastic with the surface of the collector ring 10. As a result of contacting the surface of the collector ring, a uniform pressing force is always applied to the surface of the collector ring, so that it is polished quickly and precisely.
이상에서 설명한 바와 같이 본 고안은 브러쉬매거진의 서포트아암에 상기 브러쉬매거진과 콜렉터링 사이의 간격을 조절할수 있는 장공을 형성하고, 상기 서포트아암에는 카본브러쉬 또는 연마지가 감긴 브러쉬모형을 선택적으로 장착하여 콜렉터링 연마시 상기 브러쉬모형의 장착이 용이하고, 콜렉터링에 항상 균일한 압착력이 작용하여 신속하고 깨끗하게 표면이 연마되는 효과가 있는 것이다.As described above, the present invention forms a long hole for adjusting the distance between the brush magazine and the collector ring on the support arm of the brush magazine, and the support arm is selectively mounted with a brush model wound with carbon brush or abrasive paper to collect the collector. When the ring is polished, the brush model is easily mounted, and uniform pressing force is always applied to the collector ring, thereby quickly and cleanly polishing the surface.
