본고안은 단상유도 전동기의 초기 기동시 기동 회로를 구성하여 전동기를 기동시킨다음 전동기가 일정한 속도에 이르렀을 때 기동회로를 구성하던 접점을 원심력으로 작동되는 추의 원심작동에 의하여 개방시켜 기동회로를 개로시킴으로서 전동기의 기동전류를 제한하는 단상유도 전동기 기동용 개폐기에 관한 것으로 접점의 고장이 없고 접점의 소손을 방지하여 종래것보다 오래 사용하게 되는 개폐기를 제공하기 위한 것이다.This paper constructs a starting circuit at the initial start of a single-phase induction motor and starts the motor. When the motor reaches a constant speed, it opens the contact circuit that constitutes the starting circuit by centrifugal actuation of the centrifugal force. The present invention relates to a single-phase induction motor starting switch that limits the starting current of the motor by opening the circuit. The present invention provides a switch that is used for a longer time than the conventional one by preventing contact failure and preventing burnout of the contact.
종래 원심력을 이용한 전동기의 개폐기는 제1도에 도시된 바와같이 회전축(a)에 삽설된 가동판(b)이 전동기가 회전함에 따라 원심작동되는 원심추(c),(c')에 의하여 판스프링(d)을 누르면서 접점(e)(e')을 연결하도록된 것이어서 가동판(b)이 원위치로 복귀할 때에는 접점(e),(e')을 연결하는 판스프링(d)의 탄성에 의하여 복귀되는 것이어서 전동기의 기동중 판스프링(d)의 진동이 발생되어 접점(e)(e')이 반복 접속되며 회전되는 원심추(c)(c')와 가동판(b)의 편심으로 발생되는 불균형 접속에 의한 접점(e)(e')이 소손되어 오래 사용할 수 없는 결점이 있는 것이었다.As shown in FIG. 1, a switch of a conventional motor using a centrifugal force is plated by a centrifugal weight (c), (c ') which is centrifugally operated as the movable plate (b) inserted into the rotating shaft (a) rotates as the motor rotates. It is designed to connect the contacts (e) and (e ') while pressing the spring (d). When the movable plate (b) returns to its original position, the elasticity of the leaf spring (d) connecting the contacts (e) and (e') is The vibration of the leaf spring d is generated during the starting of the motor, so that the contacts e, e 'are repeatedly connected, and the centrifugal weight c, c' and the movable plate b are rotated. The contact (e) (e ') caused by the unbalanced connection which burned out was burned out, and there existed a fault which cannot be used for a long time.
본고안은 이와 같은 종래의 결점을 제거하여 원심추와 가동판의 편심을 방지하기 위하여 원심추를 로울러로 하고 가동판을 접점을 연결하는 판스프링이 아닌 별도의 코일스프링으로 탄동되도록 하고 가동판이 접점을 직접 접속되도록 구성하여서된 것으로 이하 첨부도면에 의하여 그 구성을 상세히 설명하면 다음과 같다.In order to prevent such eccentricity between the centrifugal weight and the movable plate, this proposal makes the centrifugal roller a roller and makes the movable plate elastic with a separate coil spring instead of a plate spring connecting the contacts. It will be configured to be connected directly to the configuration described in detail below by the accompanying drawings as follows.
전동기(1)의 회전축(2)에 첨단에는 지지편(3)을 보울트로 연결하고 지지편(3)은 그 상하방에 별도의 인장 스프링(4)(4')으로 탄동되는 로울러(5)(5')를 핀(6)(6')으로 축착하여 회전축(2)과 로울러(5)(5')가 90도 방향으로 되게 하였으며 지지편(3)의 내측에는 코일스프링(7)으로 탄발되는 가동원판(8)을 회전축(2)과 공회전되게 삽착하며 가동원판(8)의 내면측에는 압지봉(9)과 삽봉통(10)(10')을 돌설하였고 전동기(1)에 부착된 고정환판(11)에 접점(12)(12')를 부착하고 삽통공(13)(13')을 천공하여 가동원판(8)이 로울러(5)(5')의 압력을 받을 때 압지봉(9)은 접점(12)(12')을 접속하고 삽통봉(10)(10')은 삽통공(13)(13') 내에서 삽통되도록 구성하여서 된 것이다.A roller 5 connected to the rotary shaft 2 of the electric motor 1 at the tip by a bolt and supporting member 3 with a separate tension spring 4 and 4 'above and below. (5 ') was pinned to the pins (6) and (6') so that the rotating shaft (2) and the rollers (5) and (5 ') were in the 90 degree direction, and the coil spring (7) inside the support piece (3). Insert the movable disk 8 to be idling with the rotating shaft 2, and the pusher rod 9 and the insertion rod (10) (10 ') on the inner surface side of the movable disk (8) and attached to the electric motor (1) Attaching the contact 12, 12 'to the fixed plate 11 and drilling the insertion hole 13, 13' so that the movable plate 8 receives the pressure of the rollers 5, 5 '. (9) connects the contact points 12 and 12 ', and the insertion rods 10 and 10' are configured to be inserted into the insertion holes 13 and 13 '.
도면중 미설명부호 14는 가동원판(8)의 환턱이다. 이와 같이된 본 고안은 전동기(1)가 정지한 상태에서는 로울러(5)(5')가 인장스프링(4)(4')에 의하여 가동원판(8)의 환턱(14)까지 오므려지게 되며 오므려진 로울러(5)(5')에 의하여 가동원판(8)이 코일스프링(7)을 탄축하면서 고정환판(11)에 근접되어 압지봉(9)이 접점(12)(12')을 눌러접속시켜 통전상태가 되며 전동기(1)를 가동시키면 회전축(2)의 회전에 의하여 지지편(5)이 회전되고 이에 따라 지지편(3)에 핀(6)(6')으로 축착된 로울러(5)(5')가 원심력에 의하여 벌어지게 되며 코일스프링(7)에 의하여 가동원판(8)이 고정환판(11)과 벌어지면서 가동원판(8)의 압지봉(9)은 접점(12)(12')을 개방하여 전기회로를 개로시키게 되는 것이며 전동기(1)의 가동이 준비하는 과정에서는 원심력이 없어지게 되어 인장스프링(4)(4')의 인장력으로 벌어졌던 로울러(5)(5')가 좁혀지면서 가동원판(8)을 고정환판(11)에 근접시켜 처음과 같이 접점(12)(12')을 폐로시킴으로서 재기동을 위한 준비상태가 되는 것이다.In the figure, reference numeral 14 denotes the threshold of the movable disc 8. The present invention as described above, the roller (5) (5 ') is closed by the tension spring (4) (4') to the rounded jaw (14) of the movable disc (8) in the state in which the electric motor 1 is stopped. The movable disc 8 compresses the coil spring 7 by the retracted rollers 5 and 5 'so as to approach the fixed plate 11 so that the presser rod 9 contacts the contacts 12 and 12'. When the electric motor 1 is operated by pressing and connecting, the support piece 5 is rotated by the rotation of the rotary shaft 2, and accordingly the rollers are pinned to the support piece 3 with pins 6 and 6 '. (5) (5 ') is opened by the centrifugal force and the movable disc 8 is opened with the fixed circular plate 11 by the coil spring 7, so that the squeezing rod 9 of the movable disc 8 is contacted 12 (12 ') is opened to open the electric circuit. In the process of preparing the motor (1), the centrifugal force disappears and the roller (5) (5) opened by the tension of the tension spring (4) (4'). ') Narrowed down By bringing the mobilizing plate 8 into close proximity to the fixed ring plate 11 and closing the contacts 12, 12 'as in the beginning, it is ready for restart.
이와같이 본고안은 종래것과 같이 접점을 개폐로 하는 판스프링으로 가동원판(8)을 탄설하지 않고 접점(12)(12') 접속과 가동원판(8)의 탄발력을 갖게하는 작동을 분리 전담하게 하였으므로 전동기(1) 가동중 접점(12)(12')의 반복접속 작용이 제거되어 아크현상이 없으며 전동기(1)의 작동이 원활하고 접점(12)(12')의 소손이 방지되었을 뿐만 아니라 가동원판(8)에 형성된 환턱(14)에 의하여 인장스프링(4)(4')에 의하여 간격이 좁혀지는 로울러(5)(5')를 회전축(2)에 대하여 정확하게 90도 방향으로 유지되게 하므로서 접점(12)(12')의 폐로상태로 정확하게 할 뿐만 아니라 로울러(5)(5')의 간격이 넓어지거나 좁혀질 때 가동원판(8)과의 마찰이 거의 없어 고장이 없고 오래 사용하게 되는 작용효과를 나타내는 것이다.In this way, the present invention is a leaf spring that opens and closes the contacts as in the prior art, and dedicates the operation of making the contact 12, 12 'connection and the actuation force of the movable disc 8 separate without the operation of the movable disc 8. Since the repetitive connection action of the contacts 12 and 12 'during operation of the motor 1 is eliminated, there is no arc phenomenon, the operation of the motor 1 is smooth, and the burnout of the contacts 12 and 12' is prevented. The rollers 5 and 5 ', which are narrowed by the tension springs 4 and 4' by the annulus 14 formed on the movable disc 8, are maintained in the exact direction of 90 degrees with respect to the rotation axis 2. This makes it possible to not only make the contact 12, 12 'closed, but also have no friction with the movable disk 8 when the distance between the rollers 5, 5' is widened or narrowed. It is to show the effect.
