이하, 본 고안의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다. 도 1은 본 발명의 일실시예에 따른 병원용 누설전류 감지장치의 구성도이다. 이를 참조하면, 상기 병원용 누설전류 감지장치(1)는 변압기(10)와, 이 변압기(10)의 2차권선측(11)에 연결되어 각종 수술실이나 응급실 등에 설치된 콘센트(13)와, 이 콘센트(13)에 접속되어 사용되는 의료용 장비(15)에 전력을 공급할 수 있도록 된 차단기(12)와, 수술실이나 응급실 등의 각종 기구 및 장비의 접지선과 연결된 접지플레이트(14)와, 상기 변압기(10)의 2차권선측(11)과 접지플레이트(14)에 각각 연결되어 그 사이의 누설전류를 감지하는 누설전류감지부(2)와, 이 누설전류감지부(2)와 연결되어 감지된 누설전류를 표시해주는 표시부(4)와, 감지된 누설전류가 설정치 이상이면 경보기(7) 또는 램프(8)를 구동하는 경보구동부(6)를 포함하여 구성된다.Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention is as follows. 1 is a block diagram of a leakage current sensing device for a hospital according to an embodiment of the present invention. Referring to this, the hospital leakage current detection device 1 is a transformer 10, the outlet 13 is connected to the secondary winding side 11 of the transformer 10 installed in various operating rooms or emergency rooms, and this outlet A circuit breaker 12 capable of supplying power to the medical equipment 15 to be used in connection with 13, a ground plate 14 connected to a ground line of various instruments and equipment such as an operating room or an emergency room, and the transformer 10 A leakage current sensing unit 2 connected to the secondary winding side 11 and the ground plate 14 of the sensing unit 2 and detecting a leakage current therebetween, and a leakage detected connected to the leakage current sensing unit 2. And a display unit 4 for displaying a current and an alarm driver 6 for driving the alarm 7 or the lamp 8 when the detected leakage current is higher than or equal to a set value.
상기 누설전류감지부(2)는 변압기(10)의 2차권선측(11)과 접지플레이트(14)에 각각 연결되어 그 사이의 전위차를 감지하고 임피던스를 이용하여 누설전류를 감지한다. 상기 표시부(4)는 아날로그 계기판 또는 디지털 계기판으로 이루어져 누설전류감지부(2)로부터 감지된 누설전류량을 시각적으로 표시한다. 상기 경보구동부(6)는 누설전류감지부(2)로부터 감지된 누설전류를 설정치와 비교하여 설정치 이상인 것으로 판단되면(약 1.7mA~2.0mA) 경보기(7)가 울리도록 하고 적색램프(8)가 점등되도록 한다. 또한, 상기 경보구동부(6)는 경보가 발생되고 램프가 점등되는 동안 누설전류가 기준 전류 이하로 다운되거나 리셋신호가 입력되면 경보발생과 램프점등이 중단되도록 한다.The leakage current detection unit 2 is connected to the secondary winding side 11 and the ground plate 14 of the transformer 10, respectively, and detects a potential difference therebetween, and detects a leakage current using an impedance. The display unit 4 consists of an analog instrument panel or a digital instrument panel to visually display the amount of leakage current detected from the leakage current detection unit 2. The alarm driver 6 compares the leakage current sensed by the leakage current detector 2 with the set value and judges that the set value is higher than the set value (about 1.7 mA to 2.0 mA) so that the alarm 7 sounds and the red lamp 8 Make sure is lit. In addition, the alarm driver 6 stops the alarm generation and the lamp lighting when the leakage current falls below the reference current or the reset signal is input while the alarm is generated and the lamp is turned on.
따라서, 상기 병원용 누설전류 감지장치(1)는 상기 변압기(10) 2차권선측(11)과 접지플레이트(14)에 연결시키기만 하면 되므로 기존의 의료용 전원공급시스템에 간편하게 설치될 수 있고, 감지된 누설전류가 표시부(4)에 표시되므로 누설전류량을 확인할 수 있으며, 설정치 이상이면 경보가 울리고 적색램프가 점등되므로 누설전류로 인한 전기적인 사고가 발생되기 전에 원인을 찾아 조치를 취할 수 있다.Therefore, since the hospital leakage current detecting device 1 only needs to be connected to the transformer 10 secondary winding side 11 and the ground plate 14, it can be easily installed in an existing medical power supply system and can be detected. Since the leakage current is displayed on the display unit 4, the amount of leakage current can be checked. If the set value is higher than the set value, an alarm sounds and the red lamp is turned on.
이상에서와 같이 본 고안에 의하면, 상기 병원용 누설전류 감지장치는 간단한 구조로 이루어져 간편하게 설치될 수 있고, 설정치 이상의 누설전류가 발생되면 이를 경보하여 전기적인 사고를 미연에 방지할 수 있도록 해준다.As described above, according to the present invention, the hospital leakage current detecting device has a simple structure and can be easily installed. When the leakage current exceeds a set value, an alarm is generated to prevent an electric accident in advance.
