본 고안은 교류전원용 단권변압기등의 탭(Tap)을 무단으로 전환연결해 나가는 습동접촉자에 관한 것으로, 특히 습동접촉자의 중간부위를 양질의 도전체로 하여 열이 발생되지 않게 한 무열(無熱) 습동접촉자에 관한 것이다.The present invention relates to a sliding contact that converts and taps a tap such as a single winding transformer for AC power without permission. In particular, a non-heating sliding contact which prevents heat from being generated by using a middle portion of the sliding contact as a good conductor. It is about.

일반적으로 교류전원용 단권변압기에 있어서는 제1도의 (c)에 도시한 바와같은 형상을 가지는 습동접촉자(1)를 수동 또는 모터의 회전구동력으로 이동시킴에 따라서 무단으로 인접한 탭(21-23)에 이동되어 정지하게 되어 있다. 즉, 제1도의 (a)에 도시한 바와같이 습동접촉자(1)를 이동시키게 될때 그 습동접촉자(1)가 탭(21)에 접촉된 상태에서 인접한 탭(22)에 접촉하게되고, 이후 습동접촉자(1)가 조금더 이동하여 정지하게 될때 그 습동접촉자(1)는 탭(21)에서 떨어지고 탭(22)에만 접촉한 상태를 유지하게 된다.In general, in the single-circuit transformer for AC power, the sliding contactor 1 having the shape as shown in FIG. 1C is moved to the adjacent tabs 21-23 by the manual or motor rotational driving force. To stop. That is, when the sliding contactor 1 is moved as shown in (a) of FIG. 1, the sliding contactor 1 comes into contact with the adjacent tab 22 in contact with the tab 21, and then the sliding contact is performed. When the contactor 1 moves a little further and stops, the sliding contactor 1 falls off from the tab 21 and remains in contact with the tab 22 only.

이와같이 습동접촉자(1)를 이동시킴에 따라 그 습동접촉자(1)는 무단으로 인접한 탭(21-23)에 이동된후 정지하게 되어 있었다. 제1도의 설명중 미설명 부호 3은 습동접촉자(1)에 연결되는 전원선이다.In this way, as the sliding contactor 1 moves, the sliding contactor 1 is moved to the adjacent tabs 21-23 without permission and stops. Reference numeral 3 in the description of FIG. 1 is a power line connected to the sliding contact 1.

그러나, 이러한 종래의 장치에 있어서는 습동접촉자가 인접한 두탭에 동시에 접촉하는 순간에 층간단락이 발생되므로 그 층간단락을 방지하기 위하여 탄소제와 같은 저항체로 습동접촉자를 구성하였다. 따라서, 습동접촉자의 전환 이동시에 층간단락을 막을 수 있게되나, 습동접촉자의 이동이 끝나 한탭에 접촉한 상태에서도 그 습동접촉자를 통하여 전원이 공급되므로 글 습동접촉자에서 전력소비가 증대될 뿐 아니라 열이 심하게 발생되고, 그 습동접촉자에서 발생되는 열을 방열시키기 위한 별도의 방열구조가 필요하게 될 뿐 아니라 그 열이 주위의 소자에 영향을 미치어 오동작을 유발하게 되는 등의 결점이 있었다.However, in such a conventional apparatus, an interlayer short circuit occurs at the moment when the sliding contact contacts the adjacent two taps at the same time, so that the sliding contact is made of a resistor made of carbon to prevent the interlayer short circuit. Therefore, it is possible to prevent the interlayer shorting during the switching movement of the sliding contact, but the power is supplied through the sliding contact even when the sliding contact is in contact with one tap, so that the power consumption of the sliding contact increases as well as heat. Not only need a separate heat dissipation structure to dissipate heat generated severely and the sliding contact, but also the heat affects the surrounding elements, causing malfunctions.

본 고안은 이러한 종래의 결점을 해결하기 위하여 , 태전환 완료시에 그 탭과 접촉되는 습동접촉자의 중간 부분을 양질의 도전체로 형성함으로써 그 습동접촉자에서 필요없는 전력소모가 발생되지 않고, 열도 발생되지 않으며, 별도의 방열구조도 설치할 필요없게 안출한 것으로, 이를 첨부된 본 고안의 도면을 참조하여 상세히 설명하면 다음과 같다.In order to solve the above-mentioned drawbacks, the present invention forms an intermediate part of the sliding contact that comes into contact with the tab when the transition is completed, so that the power consumption is not generated and heat is not generated in the sliding contact. , Without having to install a separate heat dissipation structure, when described in detail with reference to the accompanying drawings of the present invention as follows.

제2도는 본 고안의 습동접촉자 설치상태를 보인 평면도로서, 이에 도시한 바와같이, 단권변압기등의 탭(21-23)에 무단으로 전환 접촉되는 습동접촉자(1)에 있어서, 상기 습동접촉자(1)를 탄소제와 같은 저항제로 구성하되, 그 습동접촉자(1)의 중간부분에 상기 탭(21-23)과 대략 같은 폭을 가지는 양질의 도전체(1a)를 형성하여 구성한 것으로, 이와같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.2 is a plan view showing the installation state of the sliding contact of the present invention, as shown in the sliding contact (1) contactlessly contacting the tabs 21-23 of the single winding transformer, the sliding contact (1) ) Is made of a carbon-resistive material, but formed by forming a high-quality conductor 1a having a width substantially the same as that of the tabs 21-23 at the middle of the sliding contactor 1. Referring to the effect of the invention in detail as follows.

습동접촉자(1)의 전환이동시에는 제2도의 (a)에 도시한 바와 같이 무단으로 인접한 탭(22)에 접촉하게 되고, 즉 습동접촉자(1)가 탭(21)에 접촉된 상태에서 인접한 탭(22)에 접촉하게 된다. 그런데, 이때 습동접촉자(1)의 양측저항체 부분이 탭(21), (22)에 접촉되므로 그 접촉순간에 층간단락을 방지할 수 있게 된다. 이후 습동접촉자 (1)가 전환이동 완료되어 제2도의 (b)에 도시한 바와 같이 탭(22)에만 접촉된 상태에서는 그 탭(22)과 습동접촉자(1)의 도전체(1a)가 접촉된 상태를 유지하게 된다. 따라서, 이때 습동접촉자(1)의 도전체(1a)를 통하여 탭(22)에 전원이 공급되므로 습동접촉자(1)에서 필요없는 전력소모 및 열이 발생되지 않게 된다.At the time of the switching movement of the sliding contactor 1, as shown in (a) of FIG. 2, the contacting contact with the tab 22 is performed in an unauthorized manner, that is, the sliding contactor 1 is adjacent to the tab 21. Contact with the tab 22. However, at this time, since both resistance parts of the sliding contact 1 come into contact with the tabs 21 and 22, the interlayer short circuit can be prevented at the instant of contact. Thereafter, when the sliding contact 1 is switched and completed and in contact with only the tab 22 as shown in (b) of FIG. 2, the tab 22 and the conductor 1a of the sliding contact 1 come into contact with each other. Will remain intact. Therefore, since power is supplied to the tab 22 through the conductor 1a of the sliding contact 1, unnecessary power consumption and heat are not generated in the sliding contact 1.

이상에서 상세히 설명한 바와 같이 본 고안은 습동접촉자의 전환이동 완료 이후에는 그 습동접촉자의 중간부에 형성된 도전체를 통하여 전원이 공급되므로 그 습동접촉자에서 필요없는 전력소모 및 열이 발생되지 않게 되고, 또 열이 발생되지 않으므로 방열구조도 필요없게 되는 이점이 있게 된다.As described in detail above, the present invention, since the power is supplied through the conductor formed in the intermediate portion of the sliding contact after completion of the switching movement of the sliding contact, the unnecessary power consumption and heat is not generated in the sliding contact, Since no heat is generated, the heat dissipation structure is also unnecessary.
