본 고안은 전원분배기(Power Distribution Unit)의 턴온회로에 관한 것으로, 특히 회로의 턴온 스위치에 직류전원이 인가되게 하여 전원분배기 사용상의 안전성을 향상시킨 전원분배기의 턴온회로에 관한 것이다.The present invention relates to a turn-on circuit of a power distribution unit, and more particularly, to a turn-on circuit of a power distribution unit by applying a DC power to the turn-on switch of the circuit to improve the safety of the power distribution unit.

종래 전원분배기의 턴온회로에 있어서는 전원분배기의 라인전압 턴온시 그 턴온 스위치에 교류전원이 직접 인가 되고 있어 전기적 충격게 대한 안전성이 문제가 되는 단점이 있었다.In the turn-on circuit of the conventional power splitter, AC power is directly applied to the turn-on switch when the line voltage of the power splitter is turned on, so that the safety against electric shock is problematic.

제1도는 이러한 종래의 회로도로서 이에 도시한 바와 같이 전압발생기(1)가 입력측에 접속된 필터(2)의 출력단자는 스위치(SW1)(SW2)를 통해 전원분배기 단말 컨넥터에 접속하고, 상기 스위치(SW1)(SW2)를 온/오프시키는 릴레이(3)는 턴온스위치(SW3)에 접속하여 구성한 것으로, 상기에서 릴레이(3) 구동시 스위치(SW1)(SW2)가 단락되게 하였다. 이와같은 종래구성의 동작을 보면 릴레이(3)의 전원단자(AC)에 상용교류 전원이 인가된 상태에서 턴온스위치(SW3)를 온시키면 릴레이(3)를 통해 전원이 흐르게 되어 상기한 바와같이 릴레이스위치(SW1)(SW2)가 단락되고, 이에 따라 필터(2)를 통한 전원이 상기 스위치(SW1)(SW2)를 통해 전원분배기의 단말 컨넥터로 정상 전송되어 컨넥터를 통해 분배 사용되게 된다.FIG. 1 is a circuit diagram of the related art. As shown therein, an output terminal of a filter 2 having a voltage generator 1 connected to an input side thereof is connected to a power distributor terminal connector through a switch SW 1 (SW 2 ). The relay 3 for turning on / off the switch SW 1 (SW 2 ) is configured by connecting to the turn-on switch SW 3 , and the switch SW 1 (SW 2 ) is short-circuited when the relay 3 is driven. It was made. In the operation of the conventional configuration, when the turn-on switch SW 3 is turned on in the state where the commercial AC power is applied to the power terminal AC of the relay 3, the power flows through the relay 3 as described above. The relay switch SW 1 (SW 2 ) is short-circuited, whereby the power supply through the filter 2 is normally transmitted to the terminal connector of the power distributor through the switch SW 1 (SW 2 ) and used for distribution through the connector. Will be.

그러나, 이런 종래의 경우 상기한 바와같이 턴온 스위치에 교류전원이 직접 인가되고 있어 전기적 충격에 대한 안전성이 문제가 되고 있는 것이다.However, in the related art, since the AC power is directly applied to the turn-on switch as described above, safety against electric shock is a problem.

본 고안은 이와같은 종래의 단점을 감안하여 직류전압을 전원분배기의 턴온스위치에 인가함으로써 사용자의 전기적 충격을 예방하여 보다 안전하게 시스템을 온/오프할 수 있게 안출한 것으르 첨부한 제2도에 의하여 이를 상세히 설명하면 다음과 같다.The present invention is designed to prevent the user from electric shock by applying a DC voltage to the turn-on switch of the power distributor in consideration of such a conventional disadvantage, and to safely turn on / off the system according to FIG. This will be described in detail as follows.

첨부한 제2도는 본 고안에 따른 회로도로서 이에 도시한 바와같이 전압발생기 (1)가 입력측에 접속된 필터(2)의 출력단자는 교류/직류변환기(4)의 입력측에 접속하고, 그 변환기(4)의 출력측은 턴온스위치(SW3)를 통해 릴레이 구동부(5)(6)의 제어단자 (CO5) (CO6)에 접속한 것으로, 릴레이 구동부(5) (6)는 그의 제어단자(CO5) (CO6)에 일정직류 전원이 인가되면 릴레이(RL1) (RL2)가 구동되게 하고, 미설명 부호 SW1, SW2는 상기 릴레이(RL1)(RL2)의 구동시 각기 단락되는 릴레이스위치이다.2 is a circuit diagram according to the present invention, and as shown therein, the output terminal of the filter 2 having the voltage generator 1 connected to the input side is connected to the input side of the AC / DC converter 4, and the converter 4 ) Is connected to the control terminal (CO 5 ) (CO 6 ) of the relay drive unit (5) (6) through the turn-on switch (SW 3 ), the relay drive unit (5) ( 6 ) is connected to its control terminal (CO) 5 ) When a constant DC power is applied to (CO 6 ), the relays RL 1 and RL 2 are driven, and reference numerals SW 1 and SW 2 are respectively used when the relays RL 1 and RL 2 are driven. Relay switch shorted.

이와같이 구성한 본 고안의 작용 및 효과를 상세히 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured in this way as follows.

전압발생기(1)로부터 교류전원이 발생하면 교류전원은 필터(2)를 통해 정형되어 그의 출력단자를 통해 출력되어 전원 분배기의 단말 컨넥터로 인가되게 된다.When AC power is generated from the voltage generator 1, the AC power is shaped through the filter 2 and output through its output terminal to be applied to the terminal connector of the power distributor.

이때 필터(2)의 출력 교류전원이 교류/직류변환기(4)의 입력단자에 인가되어 일정직류전원으로 변환되고, 이 변환된 직류전원은 전원분배기의 턴온스위치(SW3)를 온시키게 되면 릴레이 구동부(5) (6)의 제어단자(CO5) (CO6)에 인가되어 상기한 바와같이 릴레이(RL1)(RL2)가 구동되고, 이에 따라 릴레이스위치(SW1)(SW2)가 단락되어, 필터(2)를 통한 전원이 스위치(SW1)(SW2)을 통해 전원분배기의 단말 컨넥터로 전송되어 각기 분배되어 사용되게 된다.At this time, the output AC power of the filter 2 is applied to the input terminal of the AC / DC converter 4 and converted into a constant DC power. The converted DC power turns on the turn-on switch SW 3 of the power distributor. It is applied to the control terminal (CO 5 ) (CO 6 ) of the drive unit (5) (6) to drive the relay (RL 1 ) (RL 2 ) as described above, accordingly relay switch (SW 1 ) (SW 2 ) In the short-circuit, power through the filter 2 is transmitted to the terminal connector of the power distributor through the switch SW 1 (SW 2 ) to be distributed and used respectively.

이상에서 설명한 바와같이 본 고안은 전원분배기의 턴온 스위치에 직류전원을 통하게 함으로써 릴레이를 구동시키고 릴레이 스위치를 단락시켜 전원을 분배할 수 있게 함으로써 스위치 사용상의 안전성을 향상시킨 효과가 있게 된다.As described above, the present invention enables the distribution of power by driving the relay by short-circuiting the relay switch by applying a DC power to the turn-on switch of the power splitter, thereby improving safety of switch use.
