본 발명의 전자파 제거 장치의 접지 방식을 흐름도에 따라 살펴보면 다음과 같다.Looking at the grounding method of the electromagnetic wave removing device of the present invention according to the flowchart as follows.

* 단계 1; 먼저 전자파 제거 장치의 접지 단자(170)를 사용하고자 하는 전기 기기에 접지시킨다.* Step 1; First, the ground terminal 170 of the electromagnetic wave removing device is grounded to an electric device to be used.

* 단계 2; 접지를 선택하기 위하여 스위치(140)를 그라운드 접지 위치 D-4로 전환시킨 후 전원을 연결한다.Step 2; In order to select ground, switch 140 is switched to ground ground position D-4, and then a power supply is connected.

* 단계 3, 4; 접지 감지기(180)를 전기 기기에 위치시킨 후 경보음이 울리면 스위치(140)를 접지위치 D-3로 전환시키고, 접지 감지기에서 경보음이 울리지 않으면 그라운드 접지가 이루어진 것이므로 동작을 완료한다.* Steps 3 and 4; After the ground detector 180 is placed on the electric device, when the alarm sounds, the switch 140 is switched to the ground position D-3. When the ground detector 180 does not sound, the ground is completed, so the operation is completed.

* 단계 5, 6; 스위치(140)를 다음 위치 D-3로 전환해도 접지 감지기에서 경보음이 계속 울리면 다음 위치 D-2로 전환시키고, 접지 감지기에서 경보음이 울리지 않으면 공급 전원이 단상 2선식으로서 그라운드 전위와 동일한 전원이 인가되므로 스위치(140)의 다음 위치 D-2와 연결된 전압 강하 소자(130)와 과전류 보호 소자(150), (160)를 통하여 접지된 전기 기기에서 유기되는 전자파를 흡수하고 있으므로 현 상태를 유지하고 동작을 완료한다.Steps 5 and 6; If the alarm continues to sound at the ground detector even when the switch 140 is switched to the next position D-3, switch to the next position D-2, and if the alarm does not sound at the ground detector, the power supply is a single-phase two-wire type power supply equal to the ground potential. Since the voltage is applied to the voltage drop element 130 and the overcurrent protection elements 150 and 160 connected to the next position D-2 of the switch 140, the electromagnetic wave is absorbed from the grounded electrical device. And complete the operation.

* 단계 7, 8; 스위치(140)를 다음 위치 D-2로 전환해도 접지 감지기에서 경보음이 계속 울리면 다음 위치 D-1으로 전환시키고, 접지 감지기에서 경보음이 울리지 않으면 공급 전원이 단상 2선식으로서 그라운드 전위와 동일한 전원이 인가되므로 스위치(140)의 접지위치 D-2와 연결된 전압 강하 소자130(C)와 과전류 보호 소자(150), (160)를 통하여 접지된 전기 기기에서 유기되는 전자파를 흡수하고 있으므로 현 상태를 유지하고 동작을 완료한다.Steps 7, 8; If the alarm continues to sound at the ground detector even when the switch 140 is switched to the next position D-2, switch to the next position D-1, and if the alarm does not sound at the ground detector, the power supply is a single-phase two-wire type power supply equal to the ground potential. Since it is applied to absorb the electromagnetic waves induced in the grounded electrical equipment through the voltage drop element 130 (C) and the overcurrent protection elements 150, 160 connected to the ground position D-2 of the switch 140, Keep and complete the action.

스위치(140)를 D-1 위치로 전환해도 접지 감지기에서 경보음이 계속 울리면 D-3 위치로 다시 전환한 다음 위에 설명한 동작을 반복하고, 접지 감지기에서 경보음이 울리지 않으면 공급 전원이 단상 3선식으로 전원 단자(111; L-1, L-2)의 양단에 연결된 전압 강하 소자(130)에서 양단의 평균값인 중점을 잡아 그라운드 전위로 잡아 과전류 보호 소자(150), (160)를 통하여 접지된 전기 기기에서 유기되는 전자파를 제거하고 있으므로 현 상태를 유지하여 동작을 완료한다.If the grounding detector still beeps even when the switch 140 is switched to the D-1 position, switch back to the D-3 position and repeat the above-described operation.If the grounding detector does not sound, the power supply is a single-phase three-wire system. In the voltage drop element 130 connected to both ends of the power supply terminals 111 (L-1 and L-2), the center point is set to the ground potential to be grounded through the overcurrent protection elements 150 and 160. Since the electromagnetic wave is removed from the electrical equipment, the current state is completed to complete the operation.

이상에서와 같이 본 발명에 따르면 공급되는 전원방식에 맞도록 간단한 조작과 확인으로 오동작이 없는 접지를 잡아 전자파를 그라운드 전위로 흘려 보내 전자파를 제거 할 수 있는 것이다.As described above, according to the present invention, the electromagnetic wave can be removed by sending the electromagnetic wave to the ground potential by grabbing the ground without malfunction by simple operation and confirmation to match the supplied power system.

본 발명은 간단한 스위치 조작과 접지 감지기로 접지 유무를 확인하여 접지가 필요하지만 접지가 어려운 전기 기기에 간단하게 적용할 수 있고, 인체에 유해한 전자파, 정전기 및 누설 전류 등을 그라운드 전위를 찾아 접지시켜 접지 단자를 통해 흘려 보냄으로써 전자파 및 정전기를 피할 수 있다. 또한 컴퓨터 및 주변장치와 전기 기기와 관련된 각종 전자파 증후군(DVT)의 공포에서 벗어날 수 있는 유용한 발명이다.The present invention can be easily applied to an electric device that requires grounding, but it is difficult to ground by checking the presence of grounding with a simple switch operation and a grounding detector. By flowing through the terminal, electromagnetic waves and static electricity can be avoided. It is also a useful invention that can escape the fear of various electromagnetic wave syndrome (DVT) associated with computers and peripherals and electrical equipment.
