전지의 과방전 방지장치Battery over discharge prevention device

첨부도면은 본 고안의 회로도.The accompanying drawings are circuit diagrams of the present invention.

본 고안은 승강기 비상 전원 장치에 사용되는 충전식 전지의 과방전 보호장치에 관한 것으로서, 계전기 및 제너 다이오드의 특성을 이용하여 과방전에 의한 전지의 수명을 연장하고저 한 것이다.The present invention relates to an overdischarge protection device for a rechargeable battery used in an elevator emergency power supply, and extends the life of the battery due to overdischarge by using the characteristics of a relay and a zener diode.

일반적으로 전지는 방전이 끝나버리면 성능열화를 초래하며, 특히 닉켈-카드뮴 충전식 전지인 경우에는 과방전이 지속되면 전지 내에 가스가 밀집되어 전지의 케이스를 파괴되어 재충전시킬 수 없는 경우가 통례이었다.In general, when the discharge is complete, the battery causes a performance deterioration. In particular, in the case of a nickel-cadmium rechargeable battery, when the overdischarge continues, gas is concentrated in the battery and the case of the battery cannot be recharged.

본 고안은 이러한 과방전에 의한 전지의 성능열화 및 파괴되는 결함을 해소시키기 위한 것으로, 공지한 충전식 전지부(T1, D, R2, B)에 전원 검출용 개전기(Ry1)의 접점(Y12, Y13)을 각각 접속하여 제너 다이오드(ZD) 및 전지 전압 검출용 계전기(Ry2)와, 전지 전압검출용 계전기(Ry2)의 접점(y21) 및 비상전등(L1)을 병렬로 연결함으로서 과방전에 의한 전지의 수명 단축을 감축하고저 한 것으로, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to solve the deterioration of the battery performance and destruction defects caused by the over-discharge, the contact of the power detection current detector Ry 1 to the known rechargeable battery unit (T 1 , D, R 2 , B) ( connected to Y 12, Y 13) respectively by a Zener diode (ZD) and (L 1) including contacts (y 21) and bisangjeon for battery voltage detection relay (Ry 2), and a battery voltage detection relay (Ry 2) for By connecting in parallel to reduce the shortening of the life of the battery due to over-discharge, it will be described in detail by the accompanying drawings as follows.

전원단자 1,2에 전원 검출 계전기(Ry1)을 접속한 다음 서어지 전압을 흡수하는 저항(R1) 및 콘덴서(C)의 직렬회로를 병행하여 연결하였다.The power supply detection relay Ry 1 was connected to the power supply terminals 1 and 2, and then a series circuit of the resistor R 1 and the capacitor C absorbing the surge voltage was connected in parallel.

트랜스(T1)의 전압은 다이오드와 저항(D, R2)의 정류회로를 거쳐 충전식 전지(B)에 인가된다.The voltage of the transformer T 1 is applied to the rechargeable battery B through the rectifier circuit of the diode and the resistors D and R 2 .

이러한 충전식 전지부(T1, D, R2, B)에 전원 검출계전기(Ry1)의 접점(Y11, Y12, Y13)을 연결하되 전원 검출 계전기(Ry1)의 접점(Y11)은 전원 스위치(SW) 및 승강내에 설치되어 있는 상용전등(L2)과 일체로 전원에 연결하였다.The rechargeable cell section contact point of the power detection relay (Ry 1) to (T 1, D, R 2 , B) (Y 11, Y 12, Y 13) to connect, but contact point (Y 11 of the power detection relay (Ry 1) ) Is connected to the power supply integrally with the power switch (SW) and the commercial lamp (L 2 ) installed in the lift.

그리고 전원 검출계전기(Ry1)의 접점(Y12, Y13)에 제너다이오드(ZD) 및 전지 전압 검출용 계전기(Ry2)와 전지 전압 검출용 계전기(Ry2)의 접점(Y21) 및 비상전등(L1)을 병렬로 연결시켜 구성된 것이다.And a power detection relay (Ry 1) Contact point (Y 12, Y 13) to the contact point (Y 21) of the Zener diode (ZD) and the battery voltage detection relay (Ry 2) and the battery voltage detection relay (Ry 2) for a and It is composed by connecting the emergency light (L 1 ) in parallel.

이와 같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the present invention configured in this way in detail as follows.

전원 스위치(SW)를 온(ON)시키면, 승강기의 주전원(V)에 의하여, 전원 전압 검출용 계전기(Ry1)가 동작되며, 이 계전기(Ry1)는 전원 공급시에는 접점(Y11)이 항시 접속되어 승강기 내의 상용전등(L2)가 항상 점등되게 되어 있으며, 변압기(T1)와 정류기(D)에 의해서 충전식 전지(B)에는 항상 충전 전압이 인가 되고 있다.When the power switch SW is turned ON, the power supply voltage detection relay Ry 1 is operated by the main power supply V of the elevator, and the relay Ry 1 is a contact point Y 11 when power is supplied. It is always connected, and the commercial lamp L 2 in the elevator is always lit, and the charging voltage is always applied to the rechargeable battery B by the transformer T 1 and the rectifier D.

그러나 승강기의 주전원(V)이 정전이 될 경우에는 전원 검출용 계전기(Ry1)가 동작을 멈추면서 접점(Y12, Y13)은 바뀌어 접속되면서 이 계전기의 접점(Y12, Y13)을 통하여 전지(B)에 충전되어 있던 전압에 의하여 전지의 정격전압보다 낮게 설정되어 있는 제너다이오드(ZD)가 제너(Zener) 특성으로 턴-온 되면서 전지 전압 검출 계전기(Ry2)가 동작되고(전원 공급시 접점 Y21는 접속됨) 계전기 접점(Y21)을 통하여 비상 전등(L1)이 점등된다.However, if the main power supply (V) of the elevator is to be a power failure, the relay (Ry 1) is stopping the operation contacts (Y 12, Y 13) for power detection contact point (Y 12, Y 13) of the relay as access change the The Zener diode ZD, which is set lower than the rated voltage of the battery by the voltage charged in the battery B, is turned on by the Zener characteristic to operate the battery voltage detection relay Ry 2 (power supply). When supplied, contact Y 21 is connected) Emergency light L 1 lights up via relay contact Y 21 .

그러나 장시간 동안 정전이 계속되어 전지의 전압은 서서히 감소되면 제너 다이오드(ZD)가 제너 특성에 의하여 전압 이하가 되면 제너 다이오드가 턴-오프 되면서 전지 전압 검출 계전기(Ry2)가 오프되어 접점(Y21)이 개방되고 이로 인하여 자동으로 비상전등(L1)이 동작을 멈추므로 정격전압 이하에서의 니켈-카드뮴 충전식 전지의 과방전을 막을 수 있게 된다.However, if the voltage of the battery gradually decreases due to the power failure for a long time, when the zener diode ZD becomes lower than the voltage due to the Zener characteristic, the zener diode is turned off and the battery voltage detection relay Ry 2 is turned off to make the contact Y 21. ) And the emergency light (L 1 ) stops automatically, thereby preventing over-discharge of the nickel-cadmium rechargeable battery below the rated voltage.

이상에서와 같이 정격 전압 이하에서의 비상전등(L1) 점멸시에도 계속적인 과방전에 의하여 전지의 수명이 단축되는 것을 본 고안은 정격전압 이하에서의 비상전등(L1) 점멸시에, 계전기 및 제너 다이오드의 특성을 이용하여 계속적인 과방전을 막아 전지의 수명을 연장함으로 새 전지의 교체로 인한 비용을 절감할 수 있는 효과가 있는 것이다.In that the bisangjeon such as life of the battery by prior continuous over-discharged even when (L 1) flashing of the rated voltage or less shortened as in the above at the time of the subject innovation is bisangjeon such as (L 1) flashing at or below the rated voltage, a relay, and By using the Zener diode's characteristics, it prevents continuous over-discharge and extends the battery life, thereby reducing the cost of replacing a new battery.
