본 고안은 마그네트 브레이커(Magnet Breaker)에 의하여 엘리베이터 구동용 전동기를 정지시키는 장치에 있어서, 엘리베이터의 정지시에 마그네트의 석방 시간을 단축하여 가동 효율을 높일수 있도록 한 엘리베이터의 제어 장치에 관한 것이다.The present invention relates to an elevator control apparatus for stopping an elevator drive electric motor by a magnet breaker, wherein the release time of the magnet is shortened when the elevator is stopped, thereby increasing the operating efficiency.

종래에는 제1도에 도시한 바와 같이 마그네트 코일(L1)에 흐르는 전류가 0인 상태에서는 제3도에 나타낸 바와같이 스프링(1)에 의한 기계적힘만으로 모우터 드럼(3)이 구속된 상태로 되어 엘리베이터는 정지된 상태로 있게 된다.Conventionally, as shown in FIG. 1 , when the current flowing in the magnet coil L 1 is zero, as shown in FIG. 3, the motor drum 3 is restrained only by the mechanical force of the spring 1. The elevator is in a stopped state.

이때에 제4도에 도시한 원통형 플런져(4)의 갭(Gap)은 (g1)이라고 가정한다.At this time, it is assumed that the gap Gap of the cylindrical plunger 4 shown in FIG. 4 is (g 1 ).

이와같은 상태에서 운전지령에 의하여 상승 또는 하강운전 릴레이(M1), (M2)가 구동되어 그의 해당 a 접점(릴레이 구동시에 접속되는 접점)(1a) 또는 접점(2a)중 어느 하나가 접속 상태가 되어 충분한 크기의 직류 전류(I1)가 마그네트 코일(L1)에 흐르게 되면, 코일(L1)은 여자된다.In this state, either the up or down driving relays (M 1 ) and (M 2 ) are driven by the operation command so that any one of the corresponding a contact (contacts connected during relay driving) 1a or 2a is connected. When the DC current I 1 having a sufficient magnitude flows into the magnet coil L 1 , the coil L 1 is excited.

이와같이 마그네트 코일(L1)이 여자되면 제4도에 나타낸 바와같이 화살표 방향으로 자속(ø)이 발생되어 (F)방향으로 원통형 플런져(4)가 전기적인 힘을 받아 그의 갭(g1) 보다 커지므로 해서 기계적인 힘을 가하고 있던 스프링(1)을 밀게되면 가이드 슈(Guide Shoe)(2)가 모우터 드럼(3)으로 부터 별리되어 모우터 드럼(3)은 가이드 슈(2)의 구속상태로 부터 벗어나서 운전가능하게 된다.As such, when the magnet coil L 1 is excited, magnetic flux ø is generated in the direction of the arrow as shown in FIG. 4, and the cylindrical plunger 4 receives electric force in the direction of (F), and thus its gap g 1 . When the spring (1), which has been applied with mechanical force, is pushed larger, the guide shoe (2) is separated from the motor drum (3), so that the motor drum (3) of the guide shoe (2) It can be operated out of restraint state.

반면 운행중인 엘리베이터를 정지시킬 경우에는 운행시에 접속되어 있던 릴레이 접점(1a) 또는 접점(2a)이 개방되므로 마그네트 전류(I1)를 0으로 하여 전기적인 힘에서 기계적인 힘으로 전환하게 되는데 접점(1a) 또는 접점(2a) 개방후로 부터 엘리베이터가 완전 정지되는데 까지는 마그네트론 코일(L1)의 인덕턴스(L라 침함)와 저항(R2)에 의한 시정수만큼 석방 시간이 지연 되었으며, 또한 마그네트 코일(L1)의 자기 축적 에너지를 저항(R2)을 통하여 방열 시키게 되어 엘리베이터의 가동 효율을 저하시킬 뿐 아니라, 전력 손실도 가중되는 문제점이 있었다.On the other hand, when stopping the elevator in operation, the relay contact 1a or contact 2a, which was connected at the time of operation, is opened, so that the magnet current I 1 is set to 0 to switch from electrical to mechanical force. Time constant due to the inductance of the magnetron coil (L 1 ) and the resistance (R 2 ) from (1a) or after the contact (2a) is opened until the elevator is completely stopped. As a result, the release time was delayed, and the self-accumulation energy of the magnet coil L 1 was dissipated through the resistor R2, thereby reducing the operation efficiency of the elevator and increasing the power loss.

본 고안은 이러한 점을 감안하여 간단한 구성에 의한 마그네트 회로를 부가설치하여 정지시의 마그네트의 석방시간을 단축시켜 가동 효율을 증대시킬 뿐만 아니라 마그네트가 가지고 있는 자기 에너지를 2차측인 직류전원부로 궤환(Feed Back) 시키므로서, 전력 소비도 절감할 수 있도록 안출한 것으로, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.In view of this, the present invention provides a magnet circuit with a simple configuration, which shortens the release time of the magnet during stoppage, thereby increasing operating efficiency, and feeding the magnetic energy of the magnet to the secondary DC power supply. In order to reduce power consumption, the present invention is described in detail with reference to the accompanying drawings.

제5도에서와 같이 기존의 마그네트 코일(L1)에 극성이 반대인 2차코일(L2)을 결선 하여 결합시키고, 이를 제2도에서와 같이 다이오드(D1)를 통하여 직류 전원부(10)에 접속하여 구성시킨다.As shown in FIG. 5, the secondary coil L 2 having the opposite polarity is connected to the existing magnet coil L 1 and connected thereto. As shown in FIG. 2, the DC power supply unit 10 is connected through the diode D 1 . ) To configure.

미설명 부호 DC는 직류공급 전원이다.Notation DC is a DC power supply.

이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

제2도에서 상승 또는 하강 운전 릴레이(M1), (M2)가 구동되지 않으면 그의 접점(1a) 또는 (2a)가 개방 상태가 되어 마그네트 1차 코일(L1)은 유기되지 못하므로, 이때에는 원통형 플런져(4)를 통하여 1차측코일(L1)의 자기 에너지를 2차측 코일(L2)로 유기시킬 수 있도록 하여 직류전원부(10)에 궤환시키게 되는 것이다.In FIG. 2, if the rising or falling driving relays M 1 and M 2 are not driven, the contact 1a or 2a is opened and the magnet primary coil L 1 is not induced. At this time, it is thereby possible to make an organic magnetic energy of the primary coil (L 1) to the secondary coil (L 2) through the cylindrical plunger (4) fed back to the direct current power source (10).

또한 접점(1a) 또는 접점(2a)이 개방되는 즉시 1차측 코일(L1)의 마그네트 전류(I1)가 0이 되어 전기적인 힘을 상실하게 되므로 엘리베이터를 즉시 정지시키게 된다.In addition, as soon as the contact 1a or the contact 2a is opened, the magnet current I 1 of the primary coil L 1 becomes 0 and loses the electric force, thereby immediately stopping the elevator.

만약 접점(1a) 또는 (2a)중 어느 하나가 접속 상태가 되어 엘리베이터가 가동 중일때에는 역저지용 다이오드(D1)에 의하여 2차측과는 결합되지 않고, 접점(1a) 또는 (2a)가 개방될 경우에만 결합 상태가 되어 자기에너지를 직류전원부(10)에 궤환시키게 되는 것이다.If either of the contacts 1a or 2a is in the connected state and the elevator is in operation, it is not coupled to the secondary side by the reverse blocking diode D 1 , and the contacts 1a or 2a are opened. Only when the coupling state is to return the magnetic energy to the DC power supply 10.

이와같이 동작되는 본 고안의 마그네트 브레이커 회로에 커플링 회로만을 부가하여 엘리베이터의 정지시에 마그네트의 석방시간을 단축하므로서 가동 효율을 높일 수 있을 뿐만 아니라 마그네트 코일에 축적된 자기 에너지를 저항을 통하여 열로 방출시키지 않고, 2차측 코일에 전달하여 직류 전원부에 궤환시키므로서 전력 소비도 줄일 수 있는 효과가 있는 것이다.By adding only the coupling circuit to the magnet breaker circuit of the present invention operated as described above, the operation time can be improved by shortening the release time of the magnet when the elevator is stopped. In addition, the power consumption is also reduced by transferring the coil to the secondary coil and feeding it back to the DC power supply unit.
