Description

220볼트 급전선을 이용한 유해파 및 정전기 차단회로{SCREENING CIRCUIT FOR ELEMINATING HARMFUL WAVE BY USING 220V POWER SUPPLY LINE}Harmful wave and static electricity blocking circuit using 220 volt feeder {SCREENING CIRCUIT FOR ELEMINATING HARMFUL WAVE BY USING 220V POWER SUPPLY LINE}

본 고안은 유해파 및 정전기 차폐장치에 관한 것으로, 특히 구성 부품수를 줄여 제조비용을 절감할 수 있는 220V 급전선을 이용한 유해파 및 정전기 차폐장치에 관한 것이다.The present invention relates to a harmful wave and an electrostatic shielding device, and more particularly, to a harmful wave and an electrostatic shielding device using a 220V feeder can reduce the number of components to reduce the manufacturing cost.

일반적으로, 전력회사로부터 가정 등의 수용가로 공급되는 전력은 상용교류전원이며, 대한민국의 경우를 예로 들면, 대개 단상 2선식 또는 단상 3선식의 전력이 공급되고 있다.In general, the electric power supplied from a utility company to a consumer such as a home is a commercial AC power supply, and in the case of Korea, for example, a single-phase two-wire or single-phase three-wire type electric power is generally supplied.

이 중, 상기한 단상 3선식의 경우는 두 급전선을 제외한 하나의 선이 접지선이므로, 이 접지선에 접지를 통해 유해파를 그라운드(Ground)시켜 차폐하는 유해파차단수단의 전기, 전자기기의 접지라인을 연결함으로써, 전기, 전자기기에서 발생하는 유해파를 차폐할 수 있다.In this case, in the case of the single-phase three-wire type, one line except two feed lines is a ground line, and thus, the ground line of the electric and electronic device of the harmful wave blocking means shielding the ground by shielding the harmful wave through the ground. By doing so, it is possible to shield harmful waves generated from electricity and electronic equipment.

그러나, 단상 2선식의 경우에는 접지선이 별도로 없고 2선의 급전선 중 상대적으로 전위가 낮은 선이 접지선이므로 이를 검출하여 유해파차단수단의 접지라인을 연결하여야 하는데, 일반 이용자가 단상 2선 중 접지선을 검출하기는 결코 용이한 일이 아니다.However, in the case of single-phase two-wire type, since there is no separate grounding wire and the low-potential line among two feeders is a grounding line, the grounding line of the hazardous wave blocking means should be detected and the grounding line of the single-phase two-wire is detected. Is never easy.

이에 대한민국 특허 제0120022호에서는 단상 2선 중 접지선을 자동으로 검출한 다음 스위칭소자를 작동시켜 접지대상물의 접지라인을 검출된 단상 2선 중 접지선에 연결하는 기술을 제안하고 있다.Accordingly, Korean Patent No. 0120022 proposes a technique for automatically detecting a ground line among single-phase two wires and then operating a switching device to connect the ground line of the ground object to the ground wire among the detected single-phase two wires.

그러나, 상기한 대한민국 특허 제0120022호는, 접지선 판단부와 다수의 접지선 연결 스위칭부 및 이를 구동시키기 위한 전원공급회로를 포함하고 있기 때문에, 부품수가 많아 구성이 복잡하고 제조비용이 고가인 문제점이 있었다.However, the Korean Patent No. 0120022 described above includes a ground line determining unit, a plurality of ground line connection switching units, and a power supply circuit for driving the same. .

따라서, 본 고안은 상기한 바와 같은 종래기술의 문제점을 해소하기 위해 안출한 것으로, 판단회로와 스위칭부를 구비하지 않고도 접지대상물의 접지라인을 단상 2선식의 입력전원측에 제로전위가 되도록 연결함으로써, 부품수를 줄여 구성을 단순화시키고 제조비용을 절감할 수 있는 유해파차폐장치를 제공하는 데에 그 목적이 있다.Therefore, the present invention has been made to solve the problems of the prior art as described above, by connecting the ground line of the grounding object to the zero-potential input power side of the single-phase two-wire type without having a determination circuit and a switching unit, The purpose is to provide a harmful shielding device which can reduce the number, simplify the configuration and reduce the manufacturing cost.

도 2는 본 고안을 감열선식 전기요 장판 온도 조절기에 적용한 예를 보인 회로구성도이다.Figure 2 is a circuit diagram showing an example in which the present invention is applied to a thermosensitive electric immersion plate temperature controller.

상기 복수의 분압용 저항(R1, R2)은 단상 2선식의 입력전원(AC)을 균등하게 분압하여 접지대상물(10)의 그라운드단자(G)와의 연결점(P)을 입력전원(AC)측의 접지단과 동일한 제로전위(Zero Voltage)로 하기 위한 것으로, 각 일단이 상기 단상 2선(a, b) 중 서로 다른 선에 각각 연결되고 각 타단이 상기 접지대상물(10)의 접지라인(G)에 공통 연결된다.The plurality of voltage dividing resistors R1 and R2 equally divide the single-phase two-wire input power AC, and connect the connection point P with the ground terminal G of the ground object 10 to the input power source AC side. It is intended to be the same zero voltage as the ground terminal, each end is connected to the different line of the single-phase two wires (a, b) respectively, and each other end is connected to the ground line (G) of the ground object (10) Common connection.

상기 복수의 고주파바이패스용 캐패시터(C1, C2)는 입력전원(AC)측에 혼입되어 부하측에 인가되는 고주파의 노이즈성분을 바이패스하여 제거하기 위한 것으로, 각 일단이 상기 단상 2선(a, b) 중 서로 다른 선에 각각 연결되고 각 타단이 상기 접지대상물(10)의 접지라인(G)에 공통 연결된다.The plurality of high frequency bypass capacitors C1 and C2 are for bypassing and removing high frequency noise components mixed into the input power source AC and applied to the load side. Each of the other ends of b) is connected to each other and the other end is commonly connected to the ground line (G) of the ground object (10).

전술한 본 고안에 따른 220V 급전선을 이용한 유해파 및 정전기 차단회로는 전력이 옥내로 인입되는 단말기인 콘센트(미도시) 내에 구성되거나 또는 전기, 전자제품의 전력공급 플러그(미도시)에 구성될 수도 있고, 또는 콘센트와 플러그 사이에 개재되는 별도 인터페이스 단일부품(미도시)으로 구성될 수도 있다.The harmful wave and static electricity blocking circuit using the 220V feeder according to the present invention described above may be configured in an outlet (not shown), which is a terminal into which power is drawn indoors, or in a power supply plug (not shown) of an electric or electronic product. It may also consist of a separate interface single part (not shown) interposed between the outlet and the plug.

상기와 같이 구성된 본 고안의 작용 효과를 첨부된 도면을 참조하여 설명하기로 한다.With reference to the accompanying drawings will be described the effect of the present invention configured as described above.

본 고안의 회로로 단상 2선식의 교류전원(AC)이 인가되면, 그 입력측의 양단(a, b) 간에는 소정의 전위차(예를 들면, 220V 정도)가 발생된다.When a single-phase two-wire AC power source AC is applied to the circuit of the present invention, a predetermined potential difference (for example, about 220 V) is generated between both ends a and b of the input side.

이 입력전원(AC)은 복수의 분압용 저항(R1, R2)에 의해 균등하게 분압되므로, 분압용 저항(R1, R2)과 접지대상물(10) 간의 연결점(P)은 입력전원(AC)측의 접지단과 동일한 제로전위가 된다.Since the input power supply AC is divided evenly by the plurality of voltage dividing resistors R1 and R2, the connection point P between the voltage dividing resistors R1 and R2 and the ground object 10 is connected to the input power source AC side. It has the same zero potential as the ground terminal of.

이로 인해, 접지대상물(10)의 접지라인(G)은 그라운드로 접지되는 효과가 있게 된다.Thus, the ground line G of the ground object 10 has the effect of being grounded to ground.

Since the detailed description is disclosed in Utility Model Registration No. 186547, the thermal wire type electric swash plate temperature controller 100 is omitted herein.

상기한 바와 같이 본 고안은, 복수의 저항소자만으로 구성되어 접지대상물의 접지라인을 제로전위가 되게 함으로써, 종래기술에 비해 부품수를 획기적으로 줄여 구성을 단순화하고 제조비용을 절감할 수 있는 효과가 있다.As described above, the present invention consists of only a plurality of resistance elements, so that the ground line of the grounding object becomes zero potential, thereby significantly reducing the number of parts compared to the prior art, thereby simplifying the construction and reducing the manufacturing cost. have.
