본 고안은 전기벨브에 의하여 부하에의 공급전력을 위상제어하도록한 전력제어장치에 관한 것으로서 상세하게 설명하면 전기한 전기벨브의 제어신호발생회로에 열감응성 스윗치(Sensitive swith)를 삽입함과 아울러 그 스윗치를 전기한 전기벨브에 직렬적으로 접속된 코일장치에 열적으로 밀접하여 설치하는 것에 의하여 코일장치의 이상온도 상승을 열감응성 스윗치로서 검출하여 전기벨브를 비도통으로 해서 이상시의 과대전류에 의한 회로부품의 손괴를 방지하려고 하는 것이다.The present invention relates to a power control device for phase-controlling a supply power to a load by an electric valve.

By installing the switch in thermal contact with the coil device connected in series with the switch, the abnormal temperature rise of the coil device can be detected as a thermally sensitive switch. Is to prevent the loss of.
이하에 본 고안의 실시예를 도면에 따라서 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
제1도는 전력제어장치로서 부하에 마그네트론(Magnetron)1 is a magnetron on a load as a power control device.
(MG)를 접속한 마그네트론 전원회로를 표시한 것이며,The magnetron power supply circuit connected with (MG) is shown.
(T1)은 트랜스와 같은 코일장치(T 1 ) is coil device such as transformer
(C)는 콘덴서(C) the condenser
(b)는 전기한 콘덴서(c)와 아울러 배전압발생회로를 구성하는 다이오드(Diode)(b) shows a diode constituting the double voltage generating circuit together with the capacitor (c).
(Q)는 전기한 (T1)의 1차측에 삽입된 전기밸브의 1예인 트라이악크(Q) is a triac, which is an example of an electric valve inserted into the primary side of T 1 .
(Triac : 2방향성 3단자 thyristor)(Triac: 2-way 3-terminal thyristor)
(PG)는 전기한 전기밸브(Q)를 제어하는 제어신호발생회로이며, 예컨대 가변저항을 사용한 간이구성으로 할 수가 있으며, 혹은 제2도에 표시하는 바와 같이 유니정크숀 트랜지스터를 주체로한 완화발진회로(Relaxation Oscillator)를 채용할 수도 있다.P G is a control signal generation circuit for controlling the electric valve Q, which can be configured as a simple configuration using a variable resistor, or as shown in FIG. A relaxation oscillator may be employed.
(TS)는 전기한 제어신호발생회로(PG)에 삽입된 열감응성 스윗치이며, 이 스윗치(TS)는 전기한 트랜스(T1)에 열적으로 밀접하게 설치되며 부하나 트랜스(T1)의 이상시에 그 트랜스(T1)가 발열하는 것에 따라 접점을 개방 혹은 폐쇄하여 전기밸브(Q)를 비도통으로 하도록 구성된다.(T S ) is a thermally sensitive switch inserted into the electric control signal generating circuit (PG), and this switch (T S ) is thermally installed closely to the electric transformer (T 1 ), and the load or the transformer (T 1 ). When the transformer T 1 generates heat at an abnormal condition, the contact is opened or closed to make the electric valve Q non-conductive.
이 열감응성스윗치(TS)는 제2도에 표시하는 회로에 있어서는 저항(R1)에 직렬로 접속하거나 (a위치), 콘덴서(C1)에 병렬로 접속하거나(b위치) 혹은 완화발진회로의 전원회로에 직렬로 삽입하던지(c위치)하여 사용할 수가 있다.The thermally sensitive switch T S is connected in series to the resistor R 1 in the circuit shown in FIG. 2 (a position), or connected in parallel to the capacitor C 1 (b position), or oscillation oscillation. It can be inserted into the power supply circuit of the circuit in series (c position) or used.
전기한 구성에 의하면 트랜스(T1)의 권선간이나 층간단락사고, 또는 부하의 이상상태가 생기면 1차측에 과대전류가 흘러서 전기 밸브(Q)를 포함하는 회로부품을 손괴하려고 하는 바, 그 손괴에 이를 때까지 트랜스(T1)는 발열되므로, 이 열을 열감응성 스윗치(TS)가 감지하여 접점을 열어서, 제어신호발생회로(PG)에서 전기밸브(Q)의 게이트에 입력되는 제어신호를 단절하므로 전기밸브(Q)는 비도통으로 되어 손괴가 방지된다.According to the above-described configuration, when the transformer T 1 is wound between windings, an interlayer short circuit, or an abnormal state of a load occurs, an excessive current flows to the primary side to attempt to destroy a circuit component including the electric valve Q. Since the transformer T 1 generates heat until it reaches a temperature, the heat-sensitive switch T S senses this heat to open the contact, and the control signal input to the gate of the electric valve Q in the control signal generation circuit PG. By disconnecting the electric valve (Q) is non-conducting to prevent damage.
또 이것에 의하면 트랜스(T1)에의 전류가 단절되므로 트랜스(T1)의 소손 및 부하에 의한 파괴 등도 미연에 방지되는 것이다.According to this, since the current to the transformer T 1 is disconnected, burnout of the transformer T 1 and destruction by a load are prevented in advance.
이상의 잇점에 대하여 본 실시예에 있어서는 열감응성 스윗치(TS)가 제어신호발생회로(PG)인 미약전류로에 삽입되는 것이므로 전류용량이 적은 소형의 것으로도 좋고, 또한 이 잇점을 가지고 있는 까닭에 열감응성 스윗치(TS)로 하여 주로 작동온도만을 선정조건으로 할 수 있어서, 제작이 간단하고 또한 소망하는 작동온도의 것이 용이하게 얻어진다.In view of the above advantages, since the thermally sensitive switch T S is inserted into the weak current path that is the control signal generation circuit PG, the current switch may be a small one having a small current capacity and also has this advantage. By setting the thermally sensitive switch T S , only the operating temperature can be mainly selected as the selection condition, so that the production is simple and the desired operating temperature is easily obtained.
즉 종래와 같이 마그네트론 전원회로의 1차측에 온도퓨우즈를 직렬로 삽입하고, 그 퓨우즈를 트랜스에 밀접하여 부설한 구성의 것에 있어서는 온도퓨우즈의 선정조건으로서 작동온도 이외에 전류용량도 큰 요소가 된다.That is, as in the conventional configuration in which a temperature fuse is inserted in series on the primary side of the magnetron power supply circuit and the fuse is placed close to the transformer, the element having a large current capacity in addition to the operating temperature is selected as a temperature fuse selection condition. do.
이것 때문에 온도퓨우즈의 작동온도는 항상 설정전류용량에 상당하는 작동온도 이상으로 밖에는 설정할 수 없는 관계이므로 넓은 온도범위에 걸쳐서 임의의 작동온도로서 동작하는 스윗치가 얻어지지 않는 불편이 있었으나 전기한 바 실시예에 있어서는 이러한 불편은 전혀 없다.For this reason, since the operating temperature of the temperature fuse can only be set beyond the operating temperature corresponding to the set current capacity, there is a inconvenience in that a switch operating at an arbitrary operating temperature can not be obtained over a wide temperature range. In this example, there is no such inconvenience.
또한 본 고안은 전기한 실시예에만 한정되는 것은 아니며, 본 고안의 요지에 따라 여러 가지의 형태로서 실시할 수 있다.In addition, this invention is not limited only to the above-mentioned embodiment, According to the summary of this invention, it can implement as various forms.
그중에서 몇가지 예를 열거하면List some of them
(1) 전력제어장치로서 제3도에 표시하는 바와 같이 전기밸브(Q)와 코일장치로서의 안정기(T2)와 방전등(DL)을 직렬적으로 접속한 방전등 점등장치에 본 고안을 적용한다.(1) The present invention is applied to a discharge lamp lighting device in which an electric valve Q, a ballast T 2 as a coil device, and a discharge lamp DL are connected in series as shown in FIG.
이 경우 열감응성 스윗치(TS)는 안정기(T2)에 열적으로 밀접한다.In this case, the thermally sensitive switch T S is thermally close to the ballast T 2 .
(2) 제4도에 표시하는 바와 같이 전기밸브(Q)로서 2방향성 2단자 사이 이리스타를 사용한다.(2) As shown in FIG. 4, a two-way, two-terminal ionizer is used as the electric valve Q. FIG.
이 경우 제어신호발생회로(PG)로서는 예컨대 2방향성 2단자 사이리스타(Thyristor)(Q1), 펄스트랜스(PT), 콘덴서(C2) 저항(R2)으로서 구성한 펄스신호발생회로를 사용한다.In this case, as the control signal generation circuit PG, for example, a pulse signal generation circuit configured as a two-way two-terminal thyristor Q 1 , a pulse transformer PT, and a capacitor C 2 resistor R 2 is used. do.
(3) 열감응성 스윗치(TS)로서는 스윗치적인 작용을 하는 것이면 여하한 소자를 사용하여도 좋으며, 따라서 바이메탈이나 온도퓨우즈 이외에 사이리스타나 포지스타(posistor) 등을 사용할 수도 있다.(3) As the thermally sensitive switch T S , any element may be used as long as it has a switch action. Therefore, a thyristor, a posistor, or the like may be used in addition to the bimetal or the temperature fuse.
이상과 같이 본 고안에 의하면 열감응성 스윗치를 전기밸브의 제어신호발생회로에 삽입함과 아울러 트랜스에 열적으로 밀접한 것이므로 높은 작동안정성이 얻어지는 것과 아울러 이상시에 전기 밸브 및 기타부품의 파괴를 방지하고 또 열감응성소자 자체를 소형, 소용량으로 할 수 있다는 잇점을 가지고 있다.As described above, according to the present invention, since the thermally sensitive switch is inserted into the control signal generating circuit of the electric valve and is thermally intimate with the transformer, high operation stability can be obtained and the breakage of the electric valve and other parts in the event of an abnormality is prevented. The sensitive element itself has the advantage of being able to be small and small in capacity.
또한 본 고안과 동일하게 이상시에 트랜스 등의 부품을 파괴에서 보호하는 수단으로서 제5도에 표시하는 장치가 생각된다.Similarly to the present invention, an apparatus shown in FIG. 5 is conceived as a means for protecting parts such as transformers from breakdown in the event of an abnormality.
이 장치는 트랜스(T1)의 1차측에 전류감응성 스윗치(S)를 직렬로 삽입함과 아울러 전기한 바 트랜스(T1)의 1차측 권선에 병렬로 상개형(常開型)의 열감응성 스윗치(TS)를 접속하고, 또한 그 윗치(TS)를 트랜-(T1)에 밀접하게 설치한 것이다.The device is transformer (T 1) of the ever-open type thermal sensitivity of (常開型) in parallel to the primary winding of the primary current sensitive switch (T 1) also as well as an electric bar transport insert (S) in series with the connecting the switch (T S), and further the witchi (T S) transient - one will closely installed on (T 1).
이 장치에 의하면 트랜스(T1)의 이상발열에 의하여 스윗치(TS)가 폐쇄하여 1차측 권선 양단을 단락한다.According to this apparatus, the switch T S closes due to abnormal heat generation of the transformer T 1 , and short-circuits both ends of the primary winding.
그렇게 하면 전원에서 대전류가 흐르기 때문에 전류감응성 스윗치(S)가 녹아떨어져 트랜스(T1) 등의 부품이 파괴에서 보호된다.In such a case, since a large current flows in the power supply, the current sensitive switch S melts and parts such as the transformer T 1 are protected from destruction.
이 장치에 있어서의 열감응성 스윗치(TS)는 평상시 전류를 흐르게 할 필요가 없으므로 선정조건으로서 동작온도만을 고려하면 좋기 때문에 본 고안과 동일하게 신뢰도가 높은 동작안정성이 얻어진다.Since the thermally sensitive switch T S in this apparatus does not normally need to flow a current, it is only necessary to consider the operating temperature as a selection condition, so that highly reliable operation stability is obtained as in the present invention.
