본 고안은 회전전기의 회전자에 설치되어 있는 계자권선이 회전시에 원심력에 의하여 팽출 및 변형하는 것을 방지하는 계자권선의 지지장치에 관한 것이다.The present invention relates to a field winding support device which prevents the field winding installed in the rotor of a rotating electric machine from expanding and deforming by centrifugal force during rotation.
종래 이와 같은 원심력에 의한 계자권선의 팽출 및 변형을 방지하는 데에는,제1도 및 제2도에서 1예를 보는 바와 같이,인접하는 자극 1a,1b에 권장(卷裝)된 계자권선 2a,2b간에 절연물로 구성되는 블록(3)을 계합하여,이 블록(3)을 관통하는 1개 또는 2개의 볼트(4)에 의하여 로우터림(rotor rim)(5)에 고정한 계자권선 지짖장치를 각 자극간에 1개에서 4개를 설치했었다.이와 같은 종래 구조에서는 고속회전 전기의 경우,계자권선 2a,2b에 작용한는 원심력 및 블록 1개에 대한 볼트의 계수를 증가하지 않을 수가 없게 된다. 또,블록(3)에 있어서도 그 강도를 유지하기 위하여 크게 해야할 필요가 있다. 즉,볼트(4)가 필요로하는 스페이스 및 블록(3)자신의 강도에서, 제1도에 나타내는 블록(3)의 두께는 회전전기가 고속이 되면 될수록 두꺼워진다.Conventionally, in order to prevent the expansion and deformation of the field winding by the centrifugal force, as shown in FIG. 1 and FIG. 2, the field windings 2a and 2b recommended for the adjacent magnetic poles 1a and 1b. Engage block 3 composed of an insulator in the liver, and stimulate each field winding support device fixed to rotor rim 5 by one or two bolts 4 penetrating the block 3. In the conventional structure, such a high-speed rotational electric power is forced to increase the centrifugal force and the coefficient of the bolt for one block, which act on the field windings 2a and 2b. In addition, in the block 3, it is necessary to enlarge to maintain the strength. That is, in the space required by the bolt 4 and the strength of the block 3 itself, the thickness of the block 3 shown in FIG. 1 becomes thicker as the rotating electric machine becomes high speed.
블록(3)의 두께 t가 두꺼워진다는 것은 계자권선이 블록(3)과 접촉하는 면적이 커지고 자극간을 통과하는 냉각풍에 의한 냉각효과가 적어지고,계자권선의 온도가 상승하는 결점이 있고, 또, 두께 t가 두꺼워짐에 따라서 블록(3)에 사용한느 재료로서,균일적인 강도를 지니는 절연물을 입수하기 어려워지고,강도상 신뢰성이 저하하는 동시에 값이 비싸진다.The thickening of the thickness t of the block 3 has the drawback that the area in which the field winding contacts the block 3 increases, the cooling effect caused by the cooling wind passing through the magnetic poles decreases, and the temperature of the field winding increases. In addition, as the thickness t becomes thicker, it is difficult to obtain an insulator having uniform strength as a material used for the block 3, and the reliability in strength decreases and the price becomes expensive.
본 고안은 상기와 같은 사정을 고려하여 연구된 것으로서, 그 목적하는 바는 계자권선의 냉각을 저해하는 일없이, 값싸고 신뢰성이 높은 계자권선 지지장치를 제공하는 데에 있다.The present invention has been studied in view of the above circumstances, and its object is to provide a cheap and reliable field winding support device without impeding cooling of the field winding.
이하 본 고안의 1실시예를 제 3도 및 데4도를 기초로 하여 설명한다.(6)은 절연물로 제조된 불트관통공이 없는 단순한 대형상의 블록이고,볼트관통공이 있는 압판(7)을 개재하여 2개의 볼트(8)로 샌드위치식으로 로우터림(5)에 체결 고정된다.블록(6)에 가해지는 계자권선 2a,2b의 원심력 및 블록자신의 원심력은 로우터림(5)에 고정된 볼트(8)을 개재하여 압판(7)에 의하여 지지되기 때문에 블록(6)에는 볼트관 통공이 필요로 하지 않는다는 점에서,블록(6)의 두께 t′를 대폭 엷게할 수 있게된다. 이 결과,계산권선이 블록(6)에 접촉하는 면적이 적어져서,(6)의 두께 t′를 대폭 엷게할 수 있게 된다. 이 결과, 계자권선이 블록(6)에 접촉하는 면적이 적어져서,냉각풍에 의한 냉각효과가 상승하고,계산권선의 온도상승이 저하한다. 또,강도가 균일하고 신뢰성이 높은 값싼 재료를 사용할 수가 있다. 본 고안은 상기와 같이,블록에 볼트관통공을 가공하지 아니하는 구조로 값싼 재료를 사용할 수가 있다. 본 고안은 상기와 같이,블록에 볼트관통공을 가공하지 아니하는 구조로 했지 때문에 블록의 두께를 대폭 감소할 수 있고 결좌적으로 계자권선의 온도상을을 감소하고, 또 값싸고 신뢰성이 높은 계자권순 지지장치를 제공할 수가 있다.An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. (6) is a simple large block without a butt hole made of an insulator, and is provided with a platen 7 having a bolt through hole. And the two bolts 8 are sandwiched and fixed to the low rotation 5. Since it is supported by the platen 7 via (8), since the block 6 does not require a through hole in the bolt, the thickness t 'of the block 6 can be made significantly thinner. As a result, the area where the calculation winding contacts the block 6 becomes small, so that the thickness t 'of (6) can be made significantly thin. As a result, the area where the field winding contacts the block 6 decreases, the cooling effect due to the cooling wind increases, and the temperature rise of the calculating winding decreases. In addition, a cheap material having a uniform strength and high reliability can be used. The present invention, as described above, it is possible to use a cheap material in a structure that does not process the bolt through hole in the block. The present invention has a structure that does not process the bolt through-hole in the block as described above, can significantly reduce the thickness of the block and consequently reduce the temperature phase of the field winding, and inexpensive and reliable field A winding support device can be provided.
