Description

정전압을 이용한 전기 침투 탈수기의 전원 차단 장치Power cutoff device of electric penetration dehydrator using constant voltage
본 발명은 전원 차단 장치에 관한 것으로, 더욱 상세하게는 정전압을 이용한 전기 침투 탈수기의 전원 차단 장치에 관한 것이다.The present invention relates to a power cutoff device, and more particularly, to a power cutoff device of an electric penetration dehydrator using a constant voltage.
일반적으로 전기 침투 탈수기는 슬러지와 결합된 물을 전기영동성으로 제거하기 위한 전기장을 형성시키기 위하여 직류전원이 인가되고, 그 전압차에 의해 슬러지의 함수를 탈수시키는 장치이다.In general, an electroosmotic dehydrator is a device in which a DC power is applied to form an electric field for electrophoretically removing water combined with sludge, and dewatering the sludge by the voltage difference.
이러한 전기영동식 전기 침투 탈수기는 '전기 침투 탈수기(출원번호: 10-2004-7759호)', '위상제어형 전기 탈수기(출원번호: 10-2005-9928호)', '전기 침투 탈수기(출원번호: 10-2007-46494호)', 및 '삼상교류전원을 이용한 위상제어형 전기영동식 전기 침투 탈수기(출원번호: 10-2008-44901호)' 등에 기재되어 주지된 바와 같이, 그 구조는 크게 양극(＋) 또는 음극(－)이 인가된 드럼, 드럼과 일정 공간부를 두고 설치되어 전체에 음극(－) 또는 양극(＋)이 인가된 캐터필러, 드럼과 캐터필러의 사이에 슬러지의 이송 및 탈수를 위해 권취된 여과포 벨트 등으로 구성된다.These electrophoretic electropenetrating dehydrators are 'electric penetrating dehydrator (application number: 10-2004-7759)', 'phase controlled electric dehydrator (application number: 10-2005-9928)', 'electric penetrating dehydrator (application number: 10-2007-46494), and "Phase Controlled Electrophoretic Electrophoresis Dehydrator Using Three-Phase Alternating Current Power (Application No .: 10-2008-44901), etc., the structure is largely positive (+ ) Or a drum to which a negative electrode (-) is applied, a caterpillar with a negative electrode (-) or a positive electrode (+) applied thereon, and wound for transporting and dewatering sludge between the drum and the caterpillar. And a filter cloth belt.
그런데, 이러한 전기 침투 탈수기는 300A 이상의 전류로 가압하는 장치로서, 전도성 물질로 인하여 쇼트가 발생하거나 상하 전극판의 일부가 붙었을 때는 50A 이하에서도 화재가 발생하거 전극판이 손상되는 위험이 있다.By the way, the electro-osmotic dehydrator is a device that pressurizes at a current of 300 A or more, and when a short occurs due to a conductive material or when a part of the upper and lower electrode plates is attached, there is a risk that a fire occurs even at 50 A or less and the electrode plate is damaged.
이러한 문제를 해결하기 위한 장비로서, 시중에 보급되고 있는 전원 차단 장치는 속도가 300m/sec로서, 실제 쇼트 발생 시 전원을 차단하는 속도가 느린 문제점이 있다. 이러한 지연된 차단으로 인하여 장비의 손상이 크게 발생하고, 이에 따른 손실이 큰 문제점이 있다. 예컨대, 전기 침투 탈수기의 양극과 음극 쇼트 발생 시, 큰 구멍이 생기는 문제점이 있다.As a device for solving such a problem, a commercially available power cutoff device has a speed of 300m / sec, and has a problem that a power cutoff rate is slow when an actual short occurs. Due to this delayed blocking, damage to the equipment is greatly generated, and thus there is a large problem. For example, a large hole is generated when the positive and negative shots of the electroosmotic dehydrator are generated.
한편, 전기 침투 탈수기는 정전압 방식을 채택하고 있는데, 전압은 일정하고 부하의 양에 따라 전류가 상승 또는 하강하는 방식으로 작동된다. 시중에 전류를 이용한 차단 장치가 연구되어 일부 사용되고 있으나, 쇼트 시 증가되는 전류의 양보다 실제 작업 중인 전류의 양이 커서, 이를 부하로 인식하여 차단이 잘 이루어지지 않는 문제점이 있다. 종래 기술로서, 정전류를 이용한 전원 차단 장치가 '전기탈수기의 전원차단 제어방법'(등록특허 제0946261호)에 개시되어 있다.On the other hand, the electroosmotic dehydrator adopts a constant voltage method, the voltage is constant and is operated in such a way that the current rises or falls depending on the amount of load. Although a breaker using a current has been studied in the market and used in part, there is a problem in that the current is larger than the amount of current that is increased during short, so that the current is not properly recognized as a load. As a related art, a power cut-off apparatus using a constant current is disclosed in a method for controlling power cutoff of an electric dehydrator (Patent No. 0946261).
그러나, 이러한 종래 기술에 따른 전원 차단 장치는 전술한 바와 같이, 전류를 비교하여 전원을 차단하므로, 손실 이후에 차단이 이루어지는 문제점이 있다. 그리고 쇼트가 아니고 부하가 많이 들어와도 전류는 올라가게 되는데, 이를 쇼트로 판단하여 전원을 차단시키게 되는 문제점이 있다.However, as described above, since the power cutoff device according to the prior art cuts off power by comparing current, there is a problem that the cutoff occurs after loss. And even if a lot of loads are not short, but the current goes up, there is a problem that cut off the power to determine this as a short.
본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 제안된 것으로, 그 목적은 전류가 아닌 전압을 비교하여 전원을 차단하는 정전압을 이용한 전기 침투 탈수기의 전원 차단 장치를 제공하는데 있다.The present invention has been proposed to solve the problems described above, and an object thereof is to provide a power cut device of an electric penetration dehydrator using a constant voltage to cut off the power by comparing the voltage, not the current.
본 발명의 다른 목적은, 손실 발생 전에 전원을 차단할 수 있는 정전압을 이용한 전기 침투 탈수기의 전원 차단 장치를 제공하는데 있다.Another object of the present invention is to provide a power interruption device for an electric penetration dehydrator using a constant voltage that can cut off a power source before a loss occurs.
본 발명의 또 다른 목적은, 쇼트 발생 시, 일시적으로 전압이 떨어지는 현상을 이용하여 순간적으로 쇼트를 감지 및 전원이 차단되는 정전압을 이용한 전기 침투 탈수기의 전원 차단 장치를 제공하는데 있다.Still another object of the present invention is to provide a power interruption device for an electric penetration dehydrator using a constant voltage that senses a short and turns off power by using a phenomenon in which a voltage temporarily drops when a short occurs.
본 발명의 또 다른 목적은, 설정 전압값을 작업 중 전압값과 차이를 작게 설정하여, 민감하게 작동할 수 있는 정전압을 이용한 전기 침투 탈수기의 전원 차단 장치를 제공하는데 있다.It is still another object of the present invention to provide a power cutoff device for an electric penetration dehydrator using a constant voltage which can operate sensitively by setting a set voltage value smaller than a voltage value during operation.
상기와 같은 목적을 달성하기 위한 본 발명에 따른 정전압을 이용한 전기 침투 탈수기의 전원 차단 장치는, 전기 침투 탈수기로 인가된 정전압이 정류기를 통과하여 입력되는 입력부와; 상기 입력되는 정류기의 출력 전압값을 필터링하는 필터부와; 상기 필터부를 거친 전압값을 증폭시키는 증폭기와; 설정 전압값을 입력받아, 상기 증폭된 전압값과 비교하는 비교기와; 상기 비교값에 따라 상기 정류기의 동작 감도를 조절하는 지연 회로부와; 상기 증폭된 전압값이 상기 설정 전압값보다 작은 경우, 정류기를 정지시키는 신호를 출력하는 출력부;를 포함한다.According to an aspect of the present invention, there is provided a power cut-off apparatus for an electric penetration dehydrator using a constant voltage, the input part of which a constant voltage applied to the electric penetration dehydrator passes through a rectifier; A filter unit for filtering an output voltage value of the input rectifier; An amplifier for amplifying a voltage value passed through the filter unit; A comparator for receiving a set voltage value and comparing the amplified voltage value with the amplified voltage value; A delay circuit unit for adjusting the operation sensitivity of the rectifier according to the comparison value; And an output unit configured to output a signal to stop the rectifier when the amplified voltage value is smaller than the set voltage value.
그리고 본 발명에 따른 전압을 이용한 전기 침투 탈수기의 전원 차단 장치의 상기 설정 전압값은, 사용자가 임의로 설정 가능하고, 상기 정전압과 1~2V 차이를 두고 설정하는 것에 특징이 있다.In addition, the set voltage value of the power cut-off device of the electric penetration dehydrator using the voltage according to the present invention may be arbitrarily set by the user, and is set at a difference of 1 to 2 V from the constant voltage.
본 발명은 미세한 쇼트까지 에러 없이 감지하여 전원을 차단할 수 있으므로 신뢰성이 탁월한 효과가 있다. 즉, 설정 전압값을 증폭된 전압값과 1~2V 정도로 설정하여 민감하게 작동함으로써, 쇼트로 인해 일시적으로 전압이 떨어지는 현상을 순간적으로 감지하여 전원을 차단시키는 효과가 있다.The present invention can cut off the power by detecting even a minute short without error, has excellent reliability effect. In other words, by setting the set voltage value to the amplified voltage value and about 1 ~ 2V to operate sensitively, there is an effect of temporarily detecting the phenomenon that the voltage drops due to a short circuit to cut off the power supply.
그리고 전기 침투 탈수기 이외의 환경 설비 등 DC 전압을 이용하는 대부분의 장비에 활용할 수 있고, 이러한 환경 설비에 어떠한 이물질이 혼입되더라도 설비를 안전하게 보호할 수 있는 효과도 있다.And it can be utilized in most equipment using DC voltage, such as environmental equipment other than the electric penetration dehydrator, there is an effect that can safely protect the equipment even if any foreign matter is mixed in these environmental equipment.
본 발명은 첨부된 도면에 도시된 실시예를 참고로 설명되나, 이는 예시적인 것이며, 당해 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 실시예가 가능하다는 점을 이해할 수 있을 것이다. 따라서 본 발명의 진정한 보호범위는 첨부된 청구범위에 의해서만 정해져야 할 것이다. The present invention will be described with reference to the embodiments shown in the accompanying drawings, which are exemplary, and those skilled in the art will understand that various modifications and equivalent embodiments are possible.

A constant voltage is applied to the electroosmotic dehydrator according to the present embodiment. The applied constant voltage passes through the rectifier, and the voltage value output from the electric penetration dehydrator through the rectifier is input through the input unit 10.
필터부(20)는 입력부(10)를 통해 입력되는 정류기의 출력 전압값을 필터링한다. 필터부(20)는 아날로그 필터를 이용하여 출력 전압값을 필터링한다.The filter unit 20 filters the output voltage value of the rectifier input through the input unit 10. The filter unit 20 filters the output voltage value using an analog filter.
