Description
본 고안은 전기집진기 정류형 변압기 제어카드 진단회로에 관한 것이다.The present invention relates to an electrostatic precipitator rectifying transformer control card diagnostic circuit.
일반적으로 발전소 전기집진기 제어시스템은 전기집진기를 제어하는 제어카드를 사용한다. 이러한 제어카드는 주로 아이시와 트랜지스터를 주요 구성요소로 포함하여 구성한다. 따라서 트러블 발생시 제어시스템의 카드를 하나씩 분리시켜 스페어 카드로 대체하거나 스페어카드가 없을 경우 오실로스코프와 직류 파워서플라이를 이용하여 중요부품별로 일일이 체크하면서 점검하여야하는 문제점이 있었다. 예를 들어 울산화력발전소의 경우 환경계축설비(TMS)를 가동하여 보일러스택의 배출량이 증가하므로 환경 기준치에 도달하기 전에 신속한 진단과 원인 파악 및 문제 해결이 필요하다. 그러나 이를 위한 별도의 점검장비가 없어 고장시 원인 복구가 어렵고 예방정비가 어려운 문제점이 있다.In general, power plant electrostatic precipitator control systems use a control card to control the electrostatic precipitator. Such a control card mainly includes an IC and a transistor as main components. Therefore, when a trouble occurs, the card of the control system is separated one by one and replaced with a spare card, or when there is no spare card, there is a problem of checking by checking each important part by using an oscilloscope and a DC power supply. For example, in the case of Ulsan Power Plant, the emission of boiler stack increases by operating the TMS, so it is necessary to quickly diagnose, identify the cause and solve the problem before reaching the environmental standard. However, because there is no separate inspection equipment for this, there is a problem that is difficult to repair the cause and difficult to prevent maintenance.
본 고안은 이를 해소코자 하는 것으로, 본 고안의 목적은 전기집진기 제어카드를 별도의 진단회로를 이용하여 진단할 수 있도록 한 것이다.The present invention is intended to solve this, the object of the present invention is to allow the electrostatic precipitator control card to be diagnosed using a separate diagnostic circuit.

도 2 는 본 고안의 제어카드 검사회로부(20)를 나타내는 회로도로, 펄스 입력을 미분회로(21)와 적분회로(22)를 거쳐 하이레벨을 생성하는 직류화 회로(23)와, 직류치의 입력이 있을 때 로레벨을 출력하는 비교기(24)와, 비교기(24) 출력을 반전하여 발광다이오드(LED1)를 점등시키는 낸드게이트(26)로 이루어진 클럭신호 확인부(27)와;Fig. 2 is a circuit diagram showing a control card inspection circuit section 20 of the present invention, which includes a direct current circuit 23 for generating a high level through a differential circuit 21 and an integrating circuit 22, and input of a DC value. A clock signal checking unit 27 including a comparator 24 for outputting a low level and a NAND gate 26 for inverting the output of the comparator 24 to turn on the light emitting diode LED1;
클럭에 동기되는 삼각파를 1초 단위로 반복하여 일단으로 공급받고 다른 단으로는 직류레벨을 지속적으로 인가받아 비교하여 1초 단위로 펄스를 간헐 출력하는 비교기(31)와, 펄스 출력이 있을 때 펄스를 출력하도록 미분기(32)와 적분기(33)로 이루어진 직류화 회로(34)와, 직류치의 입력이 있을 때 로레벨을 출력하는 비교기(35)와, 비교기(35) 출력을 반전하여 발광다이오드(LED3)를 1초 단위로 점등시키는 낸드게이트(36)로 이루어진 점멸회로부(37)와;The comparator 31 which is supplied to one end by repeating the triangular wave synchronized with the clock in one second unit and continuously receives the DC level in the other stage, and compares and outputs the pulse intermittently in the unit of one second, and when there is a pulse output A direct current circuit 34 composed of a differentiator 32 and an integrator 33, a comparator 35 for outputting a low level when there is an input of a DC value, and an output of the comparator 35 by inverting the light emitting diode ( A flashing circuit unit 37 made of a NAND gate 36 for lighting the LED3) in units of 1 second;
직류 전압 입력시 1 초 단위로 직류전원을 간헐 출력시키는 멀티바이브레이터(70)를 포함하여 구성한다.It comprises a multivibrator 70 for intermittently outputting the DC power in 1 second unit when the DC voltage input.
이와 같이 구성한 본 고안을 도 3 의 클럭을 기초로 함께 설명한다.The present invention configured as described above will be described with reference to the clock of FIG. 3.
도 1 에 보인 신호발생부(10)를 통한 신호 출력은 도 3 의 파형(1,2,18,19,32,4,10,11,22,28) 형태로 출력한다. 또한 정상전압이 공급되면 입력단자(T4)를 통하여 설정전압(예를들어 직류 28볼트)이 인가되어 멀티바이브레이터(70)가 구동하고 이에 따라 출력단자(T8, T7, T37)로 도 3 과 같이 1초 주기의 신호가 출력한다. 그리고 출력단자로는 교류 18볼트 60헬즈의 신호전압으로 강압되어 도 3 과 같이 인가된다. 그러면 단자(T1, T2) 로는 120 헬즈의 구형파(펄스파)가, 단자(T18)로는 삼각파가 도 1 의 신호발생부(10)로부터 발생한다. 그리고 단자(T19)로는 도 3 과 같이 1.4볼트의 직류 전압이 역시 신호발생부(10)로부터 인가된다. 따라서 비교기(31)를 통한 펄스 출력은 미분기(32), 적분기(33)를 통하여 펄스 형태로 출력되고, 이는 비교기(35)와 낸드 게이트(36)를 통하여 구형파를 출력한다. 그러나 본 고안은 클럭이 도 3 의 단자( T8, T7, T37)를 통하여 제공되는 바와 같이 1초 주기로(1초로 한정하는 것은 아니고, 주기적으로 신호가 변하는 것으로 조정 가능하다)인가되므로 제어카드를 통과한 출력인 발광다이오드(LED)가 1초 주기로 점등된다. 이는 발광다이오드(LED)가 점등되면, 진단회로 자체가 정상인지를 확인하고, 발광다이오드(LED)가 점멸하면 시험할 제어카드가 정상으로 작동하는 지를 알 수 있도록 하여 발광다이오드를 보고 전체를 구별하여 인식할 수 있도록 한다.Signal output through the signal generator 10 shown in Figure 1 is output in the form of the waveform (1, 2, 18, 19, 32, 4, 10, 11, 22, 28) of FIG. In addition, when the normal voltage is supplied, a set voltage (for example, DC 28 volts) is applied through the input terminal T4 to drive the multivibrator 70, and accordingly, the output terminals T8, T7, and T37 as shown in FIG. 3. Signal of 1 second period is output. The output terminal is stepped down to a signal voltage of AC 18 volt 60 health and is applied as shown in FIG. 3. Then, a 120-held square wave (pulse wave) is generated at the terminals T1 and T2, and a triangular wave is generated at the signal generator 10 in FIG. As the terminal T19, a direct voltage of 1.4 volts is also applied from the signal generator 10 as shown in FIG. Therefore, the pulse output through the comparator 31 is output in the form of a pulse through the differentiator 32, the integrator 33, which outputs a square wave through the comparator 35 and the NAND gate 36. However, the present invention passes through the control card because the clock is applied in one second period (not limited to one second, but can be adjusted by changing the signal periodically) as provided through the terminals T8, T7, and T37 of FIG. One output light-emitting diode (LED) is turned on every 1 second. When the LED is turned on, the diagnostic circuit itself is checked to see if it is normal, and when the LED is blinking, it is possible to know whether the control card to be tested is operating normally. Make it recognizable.
이상에서 설명한 본 고안은 전술한 실시예 및 도면에 의해 한정되는 것은 아니고, 본 고안의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경이 가능함은 본 고안이 속하는 기술분야에서 통상의 지식을 가진 자에게 있어 명백할 것이다.The present invention described above is not limited to the above-described embodiments and drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be apparent to those who have
이상과 같이 본 고안은 전기집진기 정류형 변압기를 제어하는 제어카드의 이상을 독특하게 펄스파와 삼각파와 1초주기 단위의 구형파로 출력하는 신호발생부와, 신호발생부를 통한 신호가 제어카드를 통하여 출력되면 이를 본 고안의 진단회로를 통하여 발광다이오드가 점등되도록 하되 점등과 점멸을 겸하여 발광되도록 함으로써 제어카드의 이상과 신호발생부의 이상을 구분하여 인식 가능토록 한다.As described above, the present invention is characterized in that the signal generator outputs a pulse wave, a triangular wave, and a square wave in a unit of 1 second period uniquely the control card for controlling the electrostatic precipitator rectifier transformer, and when the signal through the signal generator is output through the control card The light emitting diode is turned on through the diagnostic circuit of the present invention, but the light is turned on and blinked to emit light, thereby distinguishing the abnormality of the control card from the abnormality of the signal generator so as to be recognized.
