[산업상의 이용분야][Industrial use]
본 고안은 엔진발전기에서 발생되는 전기를 감지하여 릴레이의 작동에 의해 경고램프를 작동시킴으로써 엔지발전기의 고장을 감지하도록 된 중장비엔진발전기의 고장발생감지장치에 관한 것이다.The present invention relates to a failure detection device for a heavy-duty engine generator that detects electricity generated by an engine generator and detects a failure of an engine generator by operating a warning lamp by operating a relay.
[종래의 기술 및 그 문제점][Traditional Technology and Problems]
종래 중장비에는 밧데리 방전램프가 장착되어 있어서 밧데리가 방전되었음을 운전자에게 알려주도록 되어 있었을 뿐, 발전고장감지램프는 장착되어 있지 않았기때문에 발전기에 고장이 발생했을 경우 운전자가 이를 알 수가 없었다. 즉 발전기에 고장이 발생했을 경우 운전자가 이를 알 수 없었기 때문에 밧데리가 완전방전되어 장비가 시동이 걸리지 않게 되어 작업시간을 지연시킬 뿐만 아니라 밧데리까지 손상을 받게 되어 밧데리를 교환해야만 하는 경우가 빈번하였다.The conventional heavy equipment was equipped with a battery discharge lamp to inform the driver that the battery was discharged, but the power failure detection lamp was not installed, so the driver could not know if a failure occurred in the generator. In other words, if the generator malfunctioned, the driver could not know it, so the battery was completely discharged and the equipment did not start, which delayed the working time and caused the battery to be damaged, requiring frequent replacement of the battery.
[고안의 목적][Purpose of designation]
본 고안은 상기한 점을 감안해서 안출된 것으로, 엔진발전기에 고장이 발생할 경우 릴레이가 작동되어 자동적으로 경고램프를 점등시켜 중장비에 장착된 밧데리를 보호하고자 하는데 그 목적이 있다.The present invention was conceived in view of the above, the purpose is to protect the battery mounted on the heavy equipment by automatically turning on the warning lamp when a failure occurs in the engine generator.
[고안의 구성][Composition of design]
상기 목적을 달성하기 위한 본 고안에 따른 중장비엔진발전기의 고장발생감지장치는 이그니션스위치(IG SW)가 온됨에 따라 밧데리(BAT)로 부터의 +전류를 인가받아 트렌지스터(TR1, TR2)가 매초 수회씩 온·오프됨으로써 일정 전압을 유지시키는 레귤레이터(1)와, 상기 밧데리(BAT)로 부터의 +전류를 인가 받아 상기 레귤레이터(1)로 전류로가 형성되어 구동되는 필드코일(2), 이 필드코일(2)의 구동에 따라 발전기가 동작함으로써 AC 전압이 발생시키는 스테이터코일(3), 이 스테이터코일(3)에서 발생된 전압을 정류하는 정류기(4) 및 상기 스테이터코일(3)에서 유기된 교류전압을 정류시킨 다음 합쳐서 상기 레귤레이터(1)로 보내는 다이오드트리오(5)를 구비해서 구성된 중장비엔진 발전기에 있어서, 발전기가 정상적으로 동작할 경우 릴레이(RY)코일이 작동되어 접점(C)이 접점(D)에 접속되어 경고램프(7)가 켜지지 않도록 하고, 발전기에 이상이 발생할 경우 릴레이(RY)코일이 작동되지 않게되어 접점(C)이 접점(E)에 접속되어 경고램프(7)를 점등시켜 발전기의 고장상태를 운전자에게 경고하도록 구성되어 있다.The failure detection device of the heavy-duty engine generator according to the present invention for achieving the above object is the transistor (TR1, TR2) is applied every second by the + current from the battery (BAT) as the ignition switch (IG SW) is turned on The regulator 1 which maintains a constant voltage by being turned on and off once, and the field coil 2 which is driven by forming a current path to the regulator 1 by receiving a + current from the battery BAT. The stator coil 3 generates AC voltage by operating the generator according to the driving of the coil 2, the rectifier 4 rectifying the voltage generated by the stator coil 3, and the stator coil 3 is discharged from the stator coil 3. A heavy-duty engine generator comprising a diode trio (5) which rectifies AC voltage and sends it to the regulator (1). When the generator operates normally, the relay (RY) coil is operated by contacting it. (C) is connected to the contact (D) so that the warning lamp (7) does not turn on, and if a fault occurs in the generator, the relay (RY) coil is deactivated and the contact (C) is connected to the contact (E). The lamp 7 is turned on to warn the driver of a malfunction of the generator.
(작용)(Action)
상기한 바와 같이 구성된 본 고안은, 발전기에 이상이 발생할 경우 릴레이가 작용되어 경고램프를 점등시킴으로써 운전자에게 발전기의 고장상태를 조기에 경고하여 그로 인한 밧데리의 손상을 방지할 수 있게 된다.According to the present invention configured as described above, when an abnormality occurs in the generator, a relay is activated to warn the driver of a failure state of the generator early by turning on a warning lamp, thereby preventing damage to the battery.
(실시예)(Example)
이하 예시도면에 의거해서 본 고안의 1실시예를 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안의 1 실시예에 따른 전체적인 회로도로서, 이그니션스위치(IG SW)를 온시키면 밧데리(BAT)의 +전류가 퓨즈(F1)와 A점, 저항(R1) 및 다이오드(D1)를 통해 트렌지스터(TR1)이 베이스단에 인가됨으로써 트렌지스터(TR1)가 턴온되고, 상기 트렌지스터(TR1)가 턴온됨에 따라 상기 밧데리(BAT)의 +전류가 상기 트렌지스터(TR1)의 에미터단을 통해 접지되어 밧데리(BAT)의 -단자로 흘러 들어가게 된다. 한편 밧데리(BAT)로 부터의 +전류는 상기 퓨즈(F1)와 A점을 통해 발전기 필드코일(2)에 인가되고, 이 필드코일(2)에 인가된 전류는 온상태의 트렌지스터(TR1)의 콜렉터단과 에미터단 및 접지단으로 형성된 전류로에 따라 필드코일(2)을 구동시켜 발전기가 동작되어 전류계(AM)는 방전위치를 가르키게 된다. 한편 발전기가 동작함에 따라 스테이터코일(3)에서 AC 전압이 발생되고 이 스테이터발생전압을 다이오드트리오(5)와 다이오드(D10), 저항(R1), 다이오드(D1), 트렌지스터(TR1)의 베이스단 및 에미터단을 통해 정류기(4)중 접지된 다이오드(D4∼D6)를 통해 스테이터로 귀환하게 된다.FIG. 1 is an overall circuit diagram according to an embodiment of the present invention. When the ignition switch IG SW is turned on, the + current of the battery BAT may cause the fuse F1 and the A point, the resistor R1, and the diode D1. Transistor TR1 is applied to the base terminal through the transistor TR1, and as the transistor TR1 is turned on, the + current of the battery BAT is grounded through the emitter terminal of the transistor TR1. It flows into the negative terminal of (BAT). On the other hand, the + current from the battery BAT is applied to the generator field coil 2 through the fuse F1 and the point A, and the current applied to the field coil 2 is applied to the transistor TR1 in the on state. The generator is operated by driving the field coil 2 according to the current path formed by the collector stage, the emitter stage, and the ground terminal, and the ammeter AM indicates the discharge position. On the other hand, as the generator operates, an AC voltage is generated in the stator coil 3, and the stator generated voltage is converted into the base stages of the diode trio 5, the diode D10, the resistor R1, the diode D1, and the transistor TR1. And it is returned to the stator through the grounded diodes (D4 ~ D6) of the rectifier (4) through the emitter stage.
또 발전기가 동작함에 따라 밧데리(BAT) 단자와 A점에는 같은 전압이 나타나며 암메터(AM)는 충전위치표시하게 된다. 한편 B점에는 바로 밧데리(BAT)전압이 항상 걸려 있으나 방전전류는 저항(R2,R3)이 매우 큰 값을 나타내므로 무시할 수 있도록 제한 되어 있다.In addition, as the generator operates, the same voltage appears at the battery (BAT) terminal and point A, and the ammeter (AM) indicates the charging position. On the other hand, the battery (BAT) voltage is always applied immediately to the point B, but the discharge current is limited so that the resistance (R2, R3) shows a very large value.
한편 발전기의 회전속도가 증가함에 따라 저항(R2,R3)간의 전압은 다이오드(D2)가 도통되는 점까지 증가하고(전압동일), 그때 트렌지스터(TR2)는 도통되고 트렌지스터(TR1)는 오프된다.On the other hand, as the speed of the generator increases, the voltage between the resistors R2 and R3 increases to the point where the diode D2 conducts (voltage is the same), and the transistor TR2 conducts and the transistor TR1 turns off.
이때 트렌지스터(TR1)가 오프되면 계자전류와 전압이 낮아져 다이오드(D2)는 전류를 흐르지 못하게 되어 다시 트렌지스터(TR1)가 도통하게 되어 전압과 계자전류가증가하게 된다. 이러한 사이클이 매초 수회 반복되어 일정전압이 유지된다. 상기한 바와 같이 발전기가 정상적으로 동작하게 될 경우 F점을 통해 상기 릴레이(RY)코일의 일단에 인가된 전류는 릴레이(RY)코일을 작동시켜 릴레이(RY)의 접점(C)과 접점(D)이 접속되도록하여 경고램프(7)가 켜지지 않도록 하여 발전기가 정상적으로 작동되어 밧데리(BAT)가 정삭적으로 충전되고 있음을 운전자가 알 수 있도록 한다. 한편 발전기에 이상이 생겨 발전기가 정상적으로 동작되지 않을 경우에는 F점에서 전위가 발생되지 않게 되므로 릴레이(RY)코일이 작동되지 않아서 릴레이(RY)의 접점(C)이 접점(E)과 접속된다. 따라서 밧데리(BAT)로 부터의 +전류가 이그니션스위치(IG SW)와 퓨즈(10A), 접점(C), 접점(E) 및 경고램프(L)를 통해 접지됨으로써 경고램프(L)가 점등되어 발전기에 이상이 발생됐음을 운전자에게 알려주게 된다.At this time, when the transistor TR1 is turned off, the field current and the voltage are lowered, so that the diode D2 does not flow the current, and the transistor TR1 conducts again, thereby increasing the voltage and the field current. This cycle is repeated several times every second to maintain a constant voltage. As described above, when the generator operates normally, the current applied to one end of the relay RY coil through the point F operates the relay RY coil to contact the contact C and the contact D of the relay RY. This connection is made so that the warning lamp 7 is not turned on so that the driver knows that the generator is operating normally and the battery BAT is successfully charged. On the other hand, if an abnormality occurs in the generator and the generator does not operate normally, the potential is not generated at the point F, so that the relay RY coil is not operated and the contact C of the relay RY is connected to the contact E. Therefore, the + lamp from the battery BAT is grounded through the ignition switch (IG SW), the fuse (10A), the contact (C), the contact (E) and the warning lamp (L). The driver will be notified that something is wrong with the generator.
여기서 콘덴서(D1)는 저항(R3)을 지나는 전압을 일정하게 유지하고, 저항(R4)은 고온에서 트렌지스터(TR1)에 과도한 전류가 흐르는 것을 방지하며, 다이오드(D11)는 트렌지스터(TR1)가 오프 되었을대 계자전선에 높은 유도전압이 발생되는 것을 방지한다. 또 저장(R2)은 조정된 전압을 온도에 따라 변화하게 하는 써미스터로서 밧데리(BAT)를 충전시키는 최적의 전압을 공급해 주게 된다.Here, the capacitor D1 maintains a constant voltage across the resistor R3, the resistor R4 prevents excessive current from flowing through the transistor TR1 at a high temperature, and the diode D11 turns off the transistor TR1. This prevents the generation of high induced voltages on the field conductors. In addition, the storage (R2) is a thermistor that causes the regulated voltage to change with temperature, providing an optimal voltage for charging the battery (BAT).
[효과][effect]
상기한 바와 같이 본 고안에 의하면, 릴레이의 작동에 의해 경고램프를 점멸시켜 발전기의 고장유무를 조기에 발견하여 밧데리의 완전방전을 미연에 방지할 수 있게 되므로 밧데리를 보호할 수 있게 된다.As described above, according to the present invention, it is possible to protect the battery because it is possible to prevent the discharge of the battery in advance by early detection of the failure of the generator by blinking the warning lamp by the operation of the relay.
