본 고안은 디젤 발전기에 있어서 여자 발전기의 로터(Roter)에서 유도된 3상 교류를 직류로 변환시켜 이를 주 발전기의 로터에 공급해주는 정류링에 관한 것으로서, 정류링의 지지 및 절연구조를 개선하여 정류링의 설치 및 제작이 간편하고 제조원가를 절감할 수 있도록 함을 목적으로 안출된 것이다.The present invention relates to a rectifying ring for converting three-phase alternating current induced in the rotor of the excitation generator into a direct current in a diesel generator and supplying it to the rotor of the main generator, by improving the support and insulation structure of the rectifier ring It is designed for the purpose of making the installation and manufacture of the ring simple and reduce the manufacturing cost.

일반적으로 발전기에 회전체를 로터(Roter), 회전하지 않는 쪽을 스테이터(Stator)라고 칭하며, 발전 방식은 크게 두가지로 분류되는데 이는 회전체인 로터에 자계즉회전자계를 만들어 스테이터에서 기전력이 발생하도록 하는 방식과 다른 하나는 여자 전류를 공급하여 고정자계를 만들어 로터에서 기전력이 발생할 수 있도록 하는 방식이 있다.In general, the rotor in the generator (Roter), the non-rotating side is called the stator (Stator), the power generation is divided into two types, which is to create the magnetic field, or rotating magnetic field in the rotor of the rotor to generate the electromotive force in the stator The other method is to supply an excitation current to create a stator field so that the electromotive force can be generated in the rotor.

본 고안은 상기 발전 방식중 후자에 속하는 여자 발전기에 관한 것인데, 이는 외부로 부터 직류 전원을 공급받아 고정자계를 만들어 로터에서 기전력이 유도될 수 있도록 되어 있으며, 여자 발전기에서 유도된 3상 교류는 3개의 다이오드를 통하여 직류로 정류되어 주발전기의 로터에 공급되며, 주 발전기 및 여자 발전기의 로터는 1개의 축에 같이 설치되어 있기 때문에 접촉 부러시가 필요없다.The present invention relates to a generator generator belonging to the latter of the power generation method, which is to receive a direct current power from the outside to create a stator field so that the electromotive force can be induced in the rotor, the three-phase alternating current induced in the generator generator is 3 It is rectified by direct current through two diodes and is supplied to the rotor of the main generator. Since the rotors of the main generator and the excitation generator are installed on one shaft together, no contact break is required.

주 발전기의 로터에 공급된 직류전류는 포터를 여자시켜 회전자계를 만들어 주며, 로터가 회전하면서 자계가 변화하게 되고 따라서 스테이터에서 기전력이 유도되는 것이다.The DC current supplied to the rotor of the main generator excites the porter to create a rotating magnetic field. As the rotor rotates, the magnetic field changes and thus electromotive force is induced in the stator.

여기에서 3상교류를 직류로 변환시키는 정류기 및 바리스타는 고리형태의 정류링에 고정 설치되는데 상기 정류링 설치방법을 보면 도면 제1(a)도, 제1(b)도에서와 같이 모우터축(1')에 억지끼워 맞춤되는 보스(2')의 표면에 박판형태의 마이카를 접착제로서 일정두께 만큼 감아 마이카층(11)을 형성하여 절연역할을 하도록 선반가공으로 마이카층(11)의 표면상태를 고르게 한 후 그 표면에 정류링(3')을 열박음해서 설치하도록 되어 있다.Here, the rectifier and barista for converting three-phase alternating current into a direct current are fixedly installed in a ring-shaped rectifying ring. Referring to the method of installing the rectifying ring, as shown in FIGS. 1 (a) and 1 (b), the motor shaft The surface of the mica layer 11 is subjected to lathe processing to form a mica layer 11 by winding a thin sheet-shaped mica on the surface of the boss 2 'that is tightly fitted to the 1' as an adhesive to form a mica layer 11. After leveling, the rectifying ring 3 'is shrink-fitted on the surface.

그런데 상기 공정중 절연용 마이카층(11)과 정류링(3')의 설치 작업을 행함에 있어서 박판형태의 마이카를 보스(2')표면에 일정두께 만큼 감아준 다음, 다시 이를 선반 작업으로 표면가공해 줘야 하며 그 표면에 정류링(3')을 열박음 해야하는 등 설치 작업공정상의 번거로움과 그에 따른 작업상의 난점이 있어서 제작성이 극히 저하될 뿐만 아니라 부품의 원가구성상 상당하 영향을 미치고 있는 등의 결점이 있었다.In the process of installing the insulating mica layer 11 and the rectifying ring 3 'during the process, a thin plate-shaped mica is wound on the boss 2' surface by a predetermined thickness, and then the surface is turned by lathe work. It has to be processed, and the commutation ring (3 ') must be shrunk on the surface, which makes it difficult for the installation process and the difficulty of the work, which greatly reduces the manufacturability and significantly affects the cost structure of the parts. There was such a defect.

따라서, 본 고안은 종래의 보스와 정류링 사이의 마이카 절연상의 제반 결점을 해결하기 위하여 종래의 마이카 절연층을 배제하면서 2개의 절연판을 사용 전후면에서 링과 보스를 동시에 절연 지지토록 한 것으로 이를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Accordingly, the present invention is intended to simultaneously support both the ring and the boss on both front and back surfaces while eliminating the conventional mica insulation layer in order to solve all the defects of the mica insulation between the conventional boss and the rectifying ring. When described in detail with reference to the drawings as follows.

즉, 모우터축(1)에 압입된 보스(2)의 외측방에 정류기 및 바리스터(도시하지 않음) 고정설치용 정류링(3)을 설치함에 있어서, 정류링(3)의 길이를 보스(2)의 길이와 동일하게 형성한 다음, 중앙부위에 일정직경의 축관통공(5)을 형성하고 소정의 외경을 가지는 1쌍의 링형 절연판(4)을 모우터축(1)의 양측에서 삽입하면서 그 전후면에 공지된 수개의 볼트(6)와 너트(7)로서 관통 체결 고정시킨 다음, 절연판(4)사이의 정류링(3)이 보스(2)외주면과 일정간격(d)을 유지토록 공지된 수개의 볼트(8)로서 양측 절연판(1)과 정류링(3)을 길이방향으로 관통하면서 너트(9)로서 체결고정시켜서 된 것으로 도면 중 미설명부호 10은 정류기 및 바리스타 취부공이다.That is, in installing the rectifier and the varistor (not shown) fixed installation rectifier ring 3 in the outer side of the boss 2 press-fitted into the motor shaft 1, the length of the rectifier ring 3 is boss 2 After forming the same length as, the front and rear surfaces are formed by forming a shaft through hole 5 of constant diameter in the center portion and inserting a pair of ring-shaped insulating plates 4 having a predetermined outer diameter from both sides of the motor shaft 1. After fastening and fastening as several bolts 6 and nuts 7 known in Fig. 2, the rectifying ring 3 between the insulating plates 4 is known to maintain a constant distance d from the outer peripheral surface of the boss 2. The two bolts 8 are fastened and fastened as the nut 9 while penetrating the insulating plate 1 and the rectifying ring 3 in the longitudinal direction. In the drawing, reference numeral 10 denotes a rectifier and a barista mounting hole.

여기에서 절연판(4)의 축관통공(5) 직경은 모우터축(1)의 직경보다 약간 크게 형성하여 원활하게 삽입설치할 수 있도록 하면서 그 외경은 정류링(3)에 외경보다 약간 작게하여 결합시 정류링밖으로 돌출되지 않도록 하고(도면 제2도 참조) 그 내측면과 정류링(3) 및 보스(2)의 전후면과는 수개의 볼트(6)(8)와 너트(7)(9)를 관통 체결할 수 있는 만큼의 충분한 접촉면을 가지도록 한다.Here, the diameter of the shaft through hole 5 of the insulating plate 4 is slightly larger than the diameter of the motor shaft 1 so that the diameter of the insulating plate 4 can be easily inserted and installed. Do not protrude out of the ring (see Figure 2), and the inner surface and the front and rear surfaces of the commutation ring (3) and the boss (2) have several bolts (6) (8) and nuts (7) (9) Make sure that there is enough contact surface to penetrate through.

이상과 같이 구성된 본 고안은, 정류링(3)이 모우터축(1)의 보스(2) 전후면에 고정설치된 절연판(4)사이에 보스(2)와 일정간격(d)을 유지하도록 고정 설치되므로서 보스(2)와 정류링(3)사이에 충분한 절연효과를 얻을 수 있으며 이들 상호간의 설치 상태를 매우 견고하게 유지할 수 있는 것이다.The present invention configured as described above, the rectifying ring (3) is fixedly installed so as to maintain the boss (2) and a predetermined distance (d) between the insulating plate (4) fixed to the front and rear surfaces of the boss (2) of the motor shaft (1). Therefore, a sufficient insulation effect can be obtained between the boss 2 and the rectifying ring 3, and the installation state between them can be maintained very firmly.

따라서 본 고안은 보스(2)와 정류링(3)사이의 절연 및 상호 결합 방식을 종래의 마이카층을 지양하고 위와 같은 1쌍의 절연판(4)으로 이루어지도록 하므로서 그 조립 및 설치 작업이 매우 간편하고 수월하여 제작성을 향상시킬 수 있음은 물론, 제작시 고가제품인 마이카를 사용하지 않아도 무관하게 되어 원가절감을 꾀할 수 있는등의 특출한 효과가 있는 것이다.Therefore, the present invention is very easy to assemble and install the installation and installation of the pair of insulating plates (4) as described above to avoid the conventional mica layer between the boss (2) and the rectifying ring (3). In addition, it is easy to improve the manufacturability and, of course, does not require the use of expensive products such as mica, which has an extraordinary effect such as cost reduction.
