본 발명은 누설전류 검출장치에 관한 것으로서, 상세하게는 측정대상 전원공급선을 관통시켜 고정상태로 홀딩할 수 있으면서 착탈이 용이한 구조로 형성된 누설전류 검출장치에 관한 것이다. The present invention relates to a leakage current detecting apparatus, and more particularly, to a leakage current detecting apparatus having a structure in which a measurement subject power supply line can be passed through and held in a fixed state while being easily detachable.

일반적으로 전기설비에는 누설전류를 검출하여 누설전류에 따라 전류를 단속하는 차단기가 설치되어 사용되고 있다.Generally, electrical equipment is equipped with a breaker which detects leakage current and interrupts the current according to the leakage current.

전기설비의 일반회로에서는 누설전류 30mA이상이 되면 누전차단기를 통하여 일반 배선회로를 보호하게 규정되어 있고, 또한 동력회로에서는 누설전류 50mA 이상이 되면 누전차단기를 통하여 동력 배선회로를 보호하게 규정되어 있다.In the general circuit of electrical equipment, it is stipulated to protect general wiring circuit through leakage circuit breaker when leakage current is 30mA or more, and to protect power wiring circuit through leakage circuit breaker when leakage current is more than 50mA in power circuit.

도 1은 본 발명의 일 실시예에 따른 누설전류 검출장치를 나타내 보인 단면도이고, 도 2는 도 1의 누설전류 검출장치에 전원 공급선이 삽입된 상태를 나타내 보인 사시도이다.FIG. 1 is a sectional view showing a leakage current detecting apparatus according to an embodiment of the present invention, and FIG. 2 is a perspective view showing a state where a power supply line is inserted into the leakage current detecting apparatus of FIG.

도 1 및 도 2를 참조하면, 본 발명에 따른 누설전류 검출장치(100)는 하우징(110), 탄성패드(130), 누설전류 검출부(150)를 구비한다.Referring to FIGS. 1 and 2, a leakage current detecting apparatus 100 according to the present invention includes a housing 110, an elastic pad 130, and a leakage current detector 150.

하우징(110)은 전원 공급선(10)을 삽입하기 위해 관통되게 형성된 개방구(116)를 갖는 구조로 되어 있다.The housing 110 has a structure having an opening 116 formed to penetrate the power supply line 10 to be inserted therethrough.

여기서, 전원 공급선(10)은 상용 교류전원을 공급하는 제1 및 제2전선(11)(12)이 피복에 의해 피복된 것을 예시하였다.Here, the power supply line 10 exemplifies that the first and second electric wires 11 and 12 for supplying the commercial AC power are covered by the covering.

하우징(110)은 힌지(114)에 의해 회동될 수 있게 일단이 힌지(114)에 의해 상호 결합되어 개방구(116)를 개방 또는 폐쇄하는 제1 및 제2분할 하우징(111)(112)으로 되어 있다.The housing 110 includes first and second divided housings 111 and 112 that are coupled to each other by a hinge 114 so as to be pivotable by the hinge 114 to open or close the opening 116. [ .

제1조임스프링(141)은 제1 및 제2분할하우징(111)(112)의 타단이 상호 밀착되는 방향으로 탄성바이어스 시킬 수 있게 설치되어 있다.The first tightening spring 141 is provided so that the other ends of the first and second divided housings 111 and 112 can be elastically biased in a direction in which they are in close contact with each other.

이 경우 전원 공급선(10)을 개방구(116) 내로 삽입하고자 할 때 제1 및 제2분할하우징(111)(112)의 힌지(114) 맞은편 타단이 상호 멀어지는 방향으로 벌린 상태에서 전원 공급선(10)을 진입시키고, 이후 외력을 해제시키면 된다.In this case, when the power supply line 10 is to be inserted into the opening 116, the other ends of the first and second divided housings 111 and 112, opposite to the hinge 114, 10), and then release the external force.

탄성패드(130)는 하우징(110)의 개방구 내에 삽입된 전원 공급선(10)을 밀착에 의해 홀딩할 수 있도록 전원공급선(10)의 간섭 유무에 의해 개방구(116)가 확장 또는 축소될 수 있게 형성된 홀딩부로서 적용된 것이다.The elastic pad 130 may be expanded or contracted by the presence or absence of interference of the power supply line 10 so that the elastic pad 130 can hold the power supply line 10 inserted in the opening of the housing 110 As shown in Fig.

탄성패드(130)는 제1 및 제2분할하우징(110)각각의 개방구(116)를 형성하는 내측면에 일면이 접합되어 있다.The elastic pad 130 is bonded to one side of the inner side surface of the first and second divided housings 110 forming the opening 116.

탄성패드(130)는 삽입되는 전원 공급선(10)의 간섭에 의해 개방구(116)를 탄성적으로 확장할 수 있게 탄성소재로 형성되어 있다.The elastic pad 130 is formed of an elastic material so as to elastically expand the opening 116 due to the interference of the power supply line 10 to be inserted.

도시된 예와 다르게 홀딩부는 도 3 및 도 4에 도시된 바와 같이 하우징(210)의 개방구(116)를 회동에 의해 확장 또는 축소할 수 있게 원주방향을 따라 형성된 복수개의 조임날개(231)와, 조임날개(231)가 개방구(116)를 폐쇄하는 방향으로 탄성바이어스 되게 조임날개(231)1의 일단과 하우징(110) 사이에 결합된 제2조임 스프링(242)을 갖는 구조로 형성될 수 있다.3 and 4, the holding part includes a plurality of fastening wings 231 formed along the circumferential direction so as to expand or contract by opening the opening 116 of the housing 210, And a second tightening spring 242 coupled between one end of the tightening vane 231 and the housing 110 such that the tightening vane 231 is elastically biased in the direction of closing the opening 116 .

조임날개(242)는 원을 5분할하는 구조의 형상으로 형성되어 있고, 도시된 예와 다른 형상으로 형성될 수 있음은 물론이다.It is needless to say that the tightening vane 242 is formed in the shape of a structure in which the circle is divided into five parts, and may be formed in a shape different from the illustrated example.

또한, 제2조임스프링(242)은 조임날개(242)가 개방구(116)를 확장하는 방향으로 회동시 압축되게 설치되어 있다.Further, the second tightening spring 242 is provided so that the tightening vane 242 is compressed when rotating in the direction of expanding the opening portion 116.

한편, 하우징(210)은 앞서 도시된 구조와 다르게 환형으로 형성되어 있다.On the other hand, the housing 210 is formed in an annular shape different from the structure shown above.

이 경우 개방부(116)로 전원 공급선(10)을 진입시켜 삽입하면 된다.In this case, the power supply line 10 may be inserted and inserted into the opening 116.

누설전류 검출부(150)는 하우징(110)(210) 내에 장착되어 홀딩부에 의해 홀딩된 전원공급선(10)에 대해 누설전류를 검출하고, 검출된 누설전류값을 통신모듈(155)을 통해 설정된 수신주소로 무선으로 송출한다.The leakage current detection unit 150 detects leakage currents of the power supply line 10 mounted in the housings 110 and 210 and held by the holding unit and sets the detected leakage current value through the communication module 155 And sends it to the receiving address wirelessly.

누설전류 검출부(150)는 하우징(110)(210) 내에 설치되며 코어에 코일이 권선된 권선코어(151)와, 권선코어(151)의 코일을 통해 검출되는 누선전류를 검출하는 검출부(152)과, 검출부(153)에 제어되며 검출된 누설전류값을 설정된 수신주소로 무선으로 송출하는 통신모듈(155)로 되어 있다.The leakage current detection unit 150 includes a winding core 151 that is installed in the housings 110 and 210 and has a coil wound around the core, a detection unit 152 that detects a leakage current detected through the coil of the winding core 151, And a communication module 155 which is controlled by the detection unit 153 and wirelessly transmits the detected leakage current value to the set reception address.

여기서, 전원측에서 부하측으로 제1전선(11)과 제2전선(12)을 통해 공급되는 전류가 정상인 경우 권선코어(151)에서 발생하는 자속은 서로 상쇄되어 검출 전류는 발생하지 않으나, 누전 또는 감전이 발생하면 그에 대응되는 전류가 발생한다.Here, when the current supplied from the power source side to the load side via the first wire 11 and the second wire 12 is normal, the magnetic fluxes generated in the winding core 151 cancel each other and the detection current is not generated. However, The corresponding current is generated.

검출부(153)에 등록된 수신주소는 사용자의 스마트폰(50)의 번호가 적용될 수 있고, 이 경우 사용자는 스마트폰(50)을 통해 누설전류 검출정보를 확인할 수 있다.The number of the smartphone 50 of the user can be applied to the reception address registered in the detection unit 153. In this case, the user can confirm the leakage current detection information through the smart phone 50. [

누설전류 검출부(150)는 설정된 주기마다 검출된 누설전류 정보를 통신모듈(155)을 통해 송출하도록 구축되어 있다. The leakage current detector 150 is constructed to transmit the leakage current information detected every set period through the communication module 155.

따라서, 가정에서는 이러한 누설전류 검출장치(100)들을 가전기기 예를들면, 냉장고, 텔레비젼, 에어컨의 전원 공급선을 하우징(110)(210)의 개방구(116) 내로 삽입되게 장착하면, 스마트폰(50)을 통해 가전기기들의 누설전류 발생 여부를 확인할 수 있다.Therefore, in the home, such leakage current detecting devices 100 can be mounted on the housing 110 (210) by inserting power supply lines of household appliances such as a refrigerator, a television and an air conditioner into the openings 116 of the housings 110 and 210, 50), it is possible to confirm whether the leakage current of the household appliances is generated or not.

이상에서 설명된 누설전류 검출장치에 의하면, 검출대상 전원 공급선에 용이하게 착탈할 수 있으면서 무선으로 검출된 누설전류 정보를 제공할 수 있는 장점을 제공한다.According to the leakage current detecting apparatus described above, the leakage current information detected by radio can be provided while easily detachable from the detection target power supply line.
