Description

슈퍼캡을 이용한 이머전시밸브 액추에이터 구동회로{Emergency valve actuater driver using super capacitor}[0001] The present invention relates to an emergency valve actuator driver using a supercap,

본 발명은 슈퍼캡을 이용한 이머전시밸브 액추에이터 구동회로에 관한 것이다.The present invention relates to an emergency valve actuator driving circuit using a supercap.

일반적으로, 이머전시 액추에이터라 함은 지진, 화재 등으로 인한 정전 시에 필요한 유체의 통로를 close 또는 open 하기 위해 정전상태라 해도 필요한 동작을 외부의 에너지 보충 없이 액추에이터 스스로 필요한 동작을 할 수 있는 액추에이터이다.Generally, an emergency actuator is an actuator that can perform the necessary operation by the actuator itself without supplementing the external energy, even if it is in a power failure state, in order to close or open the fluid passage required for power failure due to earthquake or fire .

통상적으로 가장 신뢰할 수 있는 방법은 전기적인 방식보다는 기계식 방법으로 순수히 스프링의 힘만으로 작동하는 스프링리턴 방식을 선호한다(국내특허등록 제 10-7434394호). 그러나 전기적인 방식에 비해 무게가 무겁고 가격이 비싸므로 경우에 따라서는 전기적인 방식(국내특허등록 제10-0458733호)을 사용하기도 한다. 또한 전동식과 수동식을 결합하는 밸브 액추에이터가 국내 특허등록 제 10-501246호로 사용되기도 한다. In general, the most reliable method is to prefer the spring return method, which operates purely by the force of a spring by a mechanical method rather than an electrical method (Korean Patent Registration No. 10-7434394). However, since it is heavy in weight and expensive compared with the electric type, the electric type (Korean Patent Registration No. 10-0458733) may be used in some cases. In addition, a valve actuator combining an electric type and a manual type is also used as a domestic patent registration No. 10-501246.

전기적인 방식은 배터리를 사용하는 방식이 일반적이나 배터리 자체가 화학적 화합물이므로 시간에 따른 성능저하가 커 1년 보증도 어려울 정도이다. 그러나 최근에 슈퍼콘덴서(슈퍼캡)가 개발되면서 일부 기기에는 배터리보다는 슈퍼콘덴서를 사용하기도 한다. 이들의 장단점을 아래 표1과 같이 나타낼 수 있다.Electricity is a method of using a battery, but since the battery itself is a chemical compound, a performance deterioration over time is large and a one-year warranty is difficult. However, as super capacitors have recently been developed, some devices use super capacitors rather than batteries. These advantages and disadvantages can be expressed as shown in Table 1 below.

일반 배터리는 충전 시 내부저항이 큰 관계로 충전전류가 크지 않아 충전회로의 부담이 없으나 슈퍼캡을 사용하는 경우 캐패시터의 특징상 회로가 거의 쇼트(short)상태가 되어 초기에 큰 전류가 흐르므로 이를 감안하여 보호회로나 별도의 크리퍼를 추가하여 구성하여야 하므로 구성이 복잡해지고 원가 상승의 요인이 된다. 즉, 기존의 슈퍼캡을 사용하여 충전하는 경우 예를 들어 초기 충전시 슈퍼캡의 초기 전기적 특성이 쇼트상태이므로 50A 이상 계속 흘러 충전이 시작되고, 시간의 흐름에 따라 점차 작아져 1분 후에는 5A 로 작아지고, 충전이 완료됨에 따라 전류가 더 줄어든다. 그런데 현 충전회로는 최대 10A의 용량으로 기존 배터리에 적합하도록 설계되어있어, 50A에서는 3초를 견딜 수 없어 충전회로가 파손되므로 일반배터리 대신 슈퍼캡으로의 대체 사용이 어려운 실정이다. Since the internal battery has a large internal resistance when charging, the charge current is not large, so there is no burden on the charging circuit. However, when the supercap is used, the circuit becomes almost short due to the characteristics of the capacitor. It is necessary to construct a protection circuit or a separate creper so that the construction becomes complicated and the cost increases. In other words, when the conventional supercap is used for charging, for example, the initial electrical characteristic of the supercap is shorted at the time of initial charging. Therefore, the charging is started after 50A or more, And as the charging is completed, the current is further reduced. However, since the current charging circuit is designed to fit the existing battery with a capacity of up to 10A, the charging circuit is broken because it can not withstand 3 seconds at 50A, so it is difficult to replace it with a supercap instead of a regular battery.

또한 슈퍼캡(슈퍼콘덴서)을 사용하는 기술은 국내공개특허10-2012-0000523호로 알려져 있으나 이는 단순히 회로보호용으로 사용하는 것으로, 충전을 겸하여 사용하는 분야의 액추에이터에 사용된 예는 없다. 이 경우 슈퍼콘덴서(Super condenser; SUPERCAP)는 전기화학적 이중층 방법을 사용하여 형성되는 고용량 콘덴서로, 활성탄소로 이루어지며 전해질 함침 과정을 거쳐 형성되는 두 개의 다공성 전극의 절연 다공성 막(이온 전도를 보장하기 위함)에 의해 분리되어 있다. 따라서 슈퍼캡은 충전지와 통상의 콘덴서 사이의 중간 전력 및 전력밀도를 달성하여 충전지보다 빠른 에너지 회수율을 달성하는 특징이 있지만 초기 충전시의 전류가 급격히 상승하여 충전회로의 파손 요인이 되고, 이를 해결하기 위하여 별도의 고가 보호회로를 설비하여야하는 문제점이 있다. Also, a technology using a supercap (super capacitor) is known in Korean Patent Laid-Open Publication No. 10-2012-0000523. However, this technology is merely used for circuit protection, and there is no example used in an actuator in a field of use in addition to charging. In this case, a super condenser (SUPERCAP) is a high capacity condenser formed by using an electrochemical double layer method. It is composed of two porous electrodes formed by activated carbon and formed by electrolytic impregnation process (to ensure ion conduction) ). Therefore, although the supercap achieves the intermediate power and the power density between the rechargeable battery and the ordinary capacitor to achieve an energy recovery rate faster than the rechargeable battery, the current at the time of initial charging sharply rises to become a factor of failure of the charging circuit. There is a problem that a separate high-cost protection circuit must be provided.

상용교류전원을 20볼트 이하로 다운시키는 트랜스(T1);A transformer (T1) for reducing commercial AC power to 20 volts or less;

트랜스(T1)의 2차측에서 직류전원으로 정류하는 정류부(BD);A rectifying part BD rectifying the DC power from the secondary side of the transformer T1;

정류부(BD) 출력에 인가한 노이즈 제거용 콘덴서(C1);A noise removing capacitor (C1) applied to the output of the rectifying part (BD);

콘덴서(C1) 포지티브 출력단에 설치한 병렬 접속의 폴리스위치(F1)와 제 1저항(R1);A first resistor R1 and a polis position F1 of the parallel connection provided at the positive output terminal of the capacitor C1;

상기 폴리스위치(F1)나 제 1저항(R1)을 경유하여 직류전원을 충전하는 슈퍼캡(50);A super cap (50) for charging the DC power source via the first resistor (R1) and the polis position (F1);

정전시 이를 인식하여 릴레이스위치(30)의 접점이 슈퍼캡(50) 충전 전압을 인가받도록 구동하는 구동스위치(21)를 구동시키는 제어부(20)를 포함하여 구성하며;And a control unit (20) for recognizing the occurrence of a power failure and driving a drive switch (21) for driving the contact of the relay switch (30) to receive the charging voltage of the super cap (50)

상기 릴레이스위치(30)는 정전시 슈퍼캡(50)의 전원을 밸브액추에이터(10)의 모터구동부(40)에 인가하도록 구성한다.The relay switch 30 is configured to apply the power of the super cap 50 to the motor driving unit 40 of the valve actuator 10 during a power failure.

상기, 콘덴서(C1)의 네거티브 출력단에는 슈퍼캡(50)의 네거티브단이 연결되고, 슈퍼캡의 네거티브단과 포지티브단은 릴레이스위치(30)의 릴레이구동시의 접점(5, 7)을 경유하여 모터구동부(40)를 구동하도록 구성한다.The negative terminal of the supercap 50 is connected to the negative output terminal of the capacitor C1 and the negative terminal and the positive terminal of the supercap are connected to the motor 5 via the contacts 5 and 7 at the time of relay driving of the relay switch 30, So that the driving unit 40 is driven.

본 발명의 트랜스(T1)는 슈퍼캡(50)의 충전을 위한 전원에 적합하도록 19.5내지 20Volt로 설정한다. 이는 슈퍼캡(50)이 예를 들어 350mF 2.7V를 10개 직렬연결한 구성으로 하여 27V를 제공 가능토록 하기 위함이다.The transformer T1 of the present invention is set to 19.5 to 20 volts so as to be suitable for the power source for charging the super cap 50. [ This is to allow the supercap 50 to provide 27V with 10 series of 350mF 2.7V, for example.

본 발명에서의 콘덴서(C1)는 브리지정류회로로 이루어진 정류부(BD)의 맥류를 직류로 만들기 위한 노이즈 제거용이다.The capacitor (C1) in the present invention is for noise removal for making the pulsating current of the rectifying part (BD) made of a bridge rectifying circuit into a direct current.

본 발명에서의 폴리스위치(F1) 작용원리는 폴리스위치(F1)가 전기전도성 폴리머로 이루어져 반영구적으로 사용 가능한 특징이 있고, 폴리스위치(F1)에 과전류가 인가되면 과전류에 의하여 전기전도성 폴리머에서의 주울(Joule)열이 발생하고, 이 열에 의하여 폴리머스위치는 저저항체에서 고저항체로 특성이 변하는 것을 이용하는 것이다. 즉, 본 발명은 슈퍼캡(50)이 충전시 슈퍼캡(50)의 특성상 초기 0.3초 동안은 50A로 흐르고 그러면 줄 열에 의하여 온도가 70℃에 다다르고, 온도가 상승하면 전기전도성이 차단된다. The polis position (F1) in the present invention is characterized in that the polis position (F1) is made of an electrically conductive polymer and can be used semi-permanently. When an overcurrent is applied to the polis position (F1) (Joule) heat is generated. By this heat, the polymer switch utilizes the change of characteristics from a low resistance to a high resistance. That is, according to the present invention, when the supercap 50 is charged, the supercap 50 flows at a current of 50 A for the initial 0.3 seconds. Then, the temperature of the supercap 50 is 70 ° C. due to the heat of the string.

그러면 본 발명은 이 순간 폴리스위치(F1)와 병렬로 접속된 제 1저항(R1)으로 전류가 인가된다. 제 1저항(R1)은 정류가 인가되면 오옴의 법칙에 의하여 전압강하가 발생하므로, 발생한 전압강하만큼 줄어든 전원이 슈퍼캡(50)에 인가되어 슈퍼캡(50)과 회로를 이루는 다른 부품에도 과전류 인가가 차단되어 회로를 안정적으로 보호하도록 작용한다.The present invention then applies current to the first resistor R1 connected in parallel with the instantaneous police position F1. When a rectified current is applied to the first resistor R1, a voltage drop occurs due to the Ohm's law. Therefore, a power source reduced by the voltage drop is applied to the super cap 50, So that the circuit is stably protected.

상기에서 폴리스위치(F1)가 턴오프된 상태에서 2분이 경과하면 전류도 6A로 다운되어 정상전원으로 되므로 폴리스위치(F1)도 과열이 해소되어 턴온 상태를 이루므로, 그때부터는 폴리스위치(F1)를 통하여 충전이 된다.When 2 minutes have elapsed from the state where the polis position F1 is turned off, the current also falls down to 6A and becomes a normal power source, so that the polyphonic position F1 is also overheated and the turn-on state is established. As shown in FIG.

따라서 초기 충전시의 과전류 때는 폴리스위치(F1)가 턴오프되어 제 1저항(R1)에서 전압강하된 저전류 상태로 슈퍼캡(50)에 충전되도록 하여 슈퍼캡 및 회로를 보호한다. 반대로 일단 초기 과전류가 진정되면 다시 폴리스위치가 턴온하므로, 제 1저항(R1)에서의 전압 강하로 인한 손실 없이 충전을 가능토록 한다.Accordingly, when the overcurrent occurs during the initial charging, the copyswitch F1 is turned off to charge the supercap 50 in a low current state in which the voltage is lowered at the first resistor R1 to protect the supercap and the circuit. On the contrary, once the initial overcurrent is settled, the polis position is turned on again, thereby enabling charging without loss due to the voltage drop in the first resistor (R1).
