The present invention relates to an interfacial electricity meter for preventing contact and changing the structure of a connection part to facilitate installation work.
전기를 사용하는 장소에는 전기를 공급하는 공급원이 전기를 사용하는 사용자의 전기 사용량을 계량하기 위하여 전력량계를 설치하고 있다. 상기 전력량계는 전압의 크기에 따라 저압 전력량계, 고압 전력량계로, 계측항목에 따라 유효 전력량계, 무효전력량계로, 작동방법에 따라 기계식 전력량계, 전자 전력량계로, 정밀등급에 따라 보통, 정밀, 특별정밀로 나뉘고, 전기공급방식에 따라서는 단상 2선식 계기, 단상 3선식 계기, 3상 3선식 계기, 3상 4선식 계기로 구분된다.In places where electricity is used, a power supply source is installed to measure the amount of electricity used by users who use electricity. The meter is divided into low voltage meter, high voltage meter according to the size of the voltage, effective meter, reactive meter, depending on the measurement items, mechanical meter, electronic meter, depending on the operation method, divided into normal, precise, and special precision according to the precision class, According to the electricity supply method, it is divided into single-phase two-wire instrument, single-phase three-wire instrument, three-phase three-wire instrument, three-phase four-wire instrument.
도 1은 종래 3상 8선 전력량계의 전선 접속상태를 나타낸 정면도로서, 도 1에 도시된 바와 같이 종래 전력량계의 전선 접속부 구조는 상기 전력량계 접속부 구멍에 피복된 전선을 통과시켜 나사로 단단히 조여 고정시켰다.1 is a front view showing a wire connection state of a conventional three-phase eight-wire wattmeter, and as shown in FIG. 1, the wire connection structure of the conventional wattmeter is passed through a wire coated in the wattmeter connection hole and fastened with screws.
그러나, 상기와 같이 전선의 피복을 벗겨내면 피복제거 부분의 전선가닥이 퍼지고, 더욱이 전력량계를 교체하기 위하여 기존 전력량계에서 전선을 분리하면 나사 조임에 의해 피복된 부분이 휘어지고 구부러져 있어 전선이 상기 접속부 구멍에 잘 들어가지 않는다.However, if the stripping of the wire is peeled off as described above, the wire strand of the stripping portion spreads, and if the wire is removed from the existing meter to replace the electricity meter, the coated part is bent and bent by screwing, so that the wire is connected to the hole of the connection part. Doesn't go well in
또한, 상기 전력량계의 전선접속용 구멍간격(약 12mm)이 협소하여 전선삽입 과장에서 전선 한 두가닥이 옆으로 삐져나와 옆의 전선과 혼축 합선되어 아크가 발생하거나 감선사고가 발생하는 문제점이 있다.In addition, there is a problem in that a hole spacing (about 12mm) of the electricity meter is narrow and one or two strands of wires squeeze out sideways in the wire insertion section, resulting in an arc generation or a wire accident due to mixed short-circuit.
본 고안의 상기와 같은 종래기술의 제반 문제점을 해결하기 위한 것으로 그 목적은 전력량계 전선 접속부 구멍에 일측이 뚫린 반타원형의 전선삽입 리드구조를부착하여 상기 전선을 접속부에 삽입시 옆 선과 혼촉없이 안전하게 전력량계에 접속할 수 있도록 하는 혼촉방지용 전력량계를 제공하는데 있다.The purpose of the present invention is to solve all the problems of the prior art as described above, and its purpose is to attach a semi-elliptic wire insertion lead structure in which one side is perforated in a power meter wire connection hole, and safely inserts the wire into the connection part without any contact with the side line. An anti-contact watt-hour meter for connecting to

이하, 첨부된 도면을 참조하여 본 고안의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 고안의 일실시예에 따른 혼촉방지용 전력량계의 전선 접속구조를 나타낸 정면도로서, 전기의 사용량을 계량하기 위해 사용되는 전력량계(20)의 구조는 상기 전력량계(20)의 전선(23)이 삽입되는 접속부(22) 구멍에 일측이 뚫린 반타원형 전선삽입 리드구조(30)를 형성하여 이루어진다.2 is a front view showing the wire connection structure of the anti-contact electricity meter according to an embodiment of the present invention, the structure of the electricity meter 20 used to measure the amount of electricity used is the electric wire 23 of the electricity meter 20 It is made by forming a semi-elliptic wire insertion lead structure 30 having one side drilled into the hole of the connection portion 22 to be inserted.
도 3은 본 고안의 일실시예에 따른 혼촉방지용 전력량계의 전선 접속부 요부 확대도로서, 도 3에 도시된 바와 같이 전선(23)이 삽입되는 접속부(22) 구멍에 일측이 뚫린 반타원형의 리드구조(30)를 형성함으로서 전선(23)을 구멍에 맞추어 삽입할 필요없이 반타원형의 리드구조(30)에 상기 전선(22)을 안착시켜 상기 접속부(22) 구멍에 삽입한 후, 볼트(24)로 고정하는 것이다.3 is an enlarged view of a main portion of an electric wire connection part of the anti-contact electricity meter according to an embodiment of the present invention, and a semi-elliptic lead structure in which one side is drilled in a hole of a connection part 22 into which an electric wire 23 is inserted, as shown in FIG. By forming the 30, the wire 22 is seated in the semi-elliptic lead structure 30 without the need to insert the wire 23 into the hole, and then inserted into the hole of the connecting portion 22. To fix it.
이에따라, 피복된 상기 전선(23)이 옆의 전선(23)과 혼촉되거나 옆 접속부(22) 구멍에 삽입되어 아크가 발생되는 현상을 방지할 수 있는 것이다.Accordingly, the coated wire 23 may be in contact with the side wire 23 or inserted into the hole of the side connection part 22 to prevent the occurrence of an arc.
따라서, 상기 전력량계(20)에 전선(23)을 접촉 연결시 전선삽입 리드구조(30)에 피복된 전선(23)을 올려놓고, 접속부(22)구멍에 삽입한 후, 볼트(24)로 고정함으로서 옆의 전선(23)과 엉키거나 옆으로 삐져서 다른 구멍에 삽입되는 것을 방지할 수 있는 것이다.Accordingly, the wire 23 coated on the wire insertion lead structure 30 is placed on the electricity meter 20 when the wire 23 is in contact with the electricity meter 20, and inserted into the hole of the connection part 22, and then fixed with the bolt 24. By being tangled with the side wires 23 or squeezed sideways, it is possible to prevent them from being inserted into other holes.
이상에서는 본 고안의 바람직한 실시예에 대하여 도시하고 또한 설명하였으나, 본 고안의 상기한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 본 고안이 속하는 분야에서 통상의 지식을 가진자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 기재된 청구범위 내에 있게 된다.In the above described and illustrated with respect to the preferred embodiment of the present invention, but is not limited to the above-described embodiment of the present invention, without departing from the gist of the present invention claimed in the claims are common in the field Various modifications may be made by those skilled in the art, and such modifications are intended to fall within the scope of the appended claims.
이상에서 설명한 바와 같이 본 고안에 의하면, 전선이 전력량계 접속부 구멍에 쉽게 들어가고, 피복이 재거된 상기 전선가닥이 옆으로 삐지거나 다른 접속부 구멍으로 삽입되는 것을 방지하여 합선에 의한 안전사고를 예방하고, 작업을 손쉽게 할 수 있는 효과가 있다.As described above, according to the present invention, the electric wire easily enters the wattmeter connection hole, and the wire strand having the sheath removed is prevented from being squeezed to the side or inserted into another connection hole to prevent safety accidents caused by short circuits.
