Description
본 고안은 전력량계 단자 안전카바에 관한 것으로 보다 상세하게는 스프링 내,외부에 절연고무로 몰딩하여 상,하 압축이 가능한 파형관을 만들어 전력량계 리드선에 조립 부착하여 전력량계 결선(교환) 작업시 전선의 나선부분을 전력량계 안전카바 스프링이 팽창하면서 절연을 유지하도록 하는 전력랑계 단자 안전카바에 관한 것이다.The present invention relates to a power meter terminal safety cover, and more specifically, to form a corrugated pipe capable of compressing up and down by molding with insulating rubber inside and outside of the spring, and then attaching it to the wattmeter lead wire, Power meter safety cover relates to a power meter terminal safety cover to maintain insulation while the spring expands.
본 고안은 배전 사업소에 광범위하게 산재되어 있는 전력량계 및 계기업무에 종사하는 직원들의 안전확보를 위하여 본 고안을 하게 되었다. 종래의 전력량계 부설 위치가 협소하고 조명, 환기등이 부적당한 장소에 많이 취부되어 있어 작업조건이 불리한 경우가 대부분이며 또한 전력량계 설치 및 철거 작업시 활선 상태에서 작업하는 경우가 대부분으로서 전력량계 결선 작업시는 상간혼촉 등으로 인한 아-크 화상사고 방지에 만전을 기해야 한다. 또한 저압에 접촉하더라도 안전사고 우려가 없다는 저압 경시풍조가 팽배되어 노출된 채 작업을 하다 감전 및 실명 등의 안전사고가 계속 발생되고 있다. 작업자들의 안전성 확보 및 작업 효율성 향상측면에서 여러 가지 방법이 제시되었는데 삼상전력량계의 상간혼촉으로 인한 아-크 화상사고 방지를 위해 실리콘 튜브를 전력량계 부설시에 사용토록 되어 있다.The present invention was devised to secure the safety of employees in the electricity meter and instrument work widely distributed in the distribution office. In most cases, the conventional electricity meter installation location is narrow and the lighting, ventilation, etc. are installed in an inappropriate place, and the working conditions are often disadvantageous. Care should be taken to prevent arc burns caused by inter-phase mixing. In addition, low pressure over time wind tunnels, which have no concern for safety accidents even when they are in contact with low pressures, are exposed and work accidents such as electric shock and blindness continue to occur. In order to secure workers' safety and improve work efficiency, various methods have been proposed. In order to prevent arc burns caused by interphase mixing of three-phase meters, silicon tubes are used to install them.
전력량계 교환과 같은 작업시 실리콘 튜브로 노출개소를 방호한후 작업에 임하면 상간혼촉으로 인한 안전사고는 방지할 수도 있으나 번거롭기 때문에 안전조치 를 생략하는 경우가 많다. 또한 실리콘 튜브 설치로 안전하게 작업할 수도 있으나 현장에서 실리콘 튜브를 설치하여 작업하는 경우는 거의 없다.If work is performed after protecting exposure point with silicon tube during work such as changing electricity meter, safety accidents due to interphase mixing may be prevented, but it is cumbersome, so take safety measures Are often omitted. You can also work safely with silicone tube installations, but rarely do you work with silicone tubes in the field.
본 고안은 전력량계 단자의 스프링 내,외부에 절연고무로 몰딩하여 상,하 압축이 가능한 파형관을 만들어 전력량계 리드선에 조립 부착하여 전력량계 결선(교환) 작업시 전선의 나선부분을 전력량계 안전카바 스프링이 팽창하면서 절연시킴을 목적으로 한다.The present invention forms a corrugated pipe that can be compressed up and down by insulated rubber inside and outside of the spring of the electricity meter terminal, and attaches it to the electricity meter lead wire to expand the spiral part of the wire during electricity meter connection (exchange) work. To insulate.

＜도면의 주요부분에 대한 부호의 설명＞<Description of the code | symbol about the principal part of drawing>
1: 전선(피복제거) 2: 스프링(고무로 몰딩)1: Wire (Uncoated) 2: Spring (Rubber Molding)
3: 케이블 타이 4: 단자 안전카바3: cable tie 4: terminal safety cover
본 고안의 전력량계 단자 안전카바를 조립하여 이를 전선에 결선한 후, 고장시 철거 및 교체하는데 이용한다.Assemble the safety meter terminal safety cover of the present design and connect it to the wire, and then use it to remove and replace it in case of failure.
* 전력량계 단자 안전카바의 조립* Assembly of power meter terminal safety cover
본 고안은 전력량계 단자에 접속할 전선(1)을 약 30mm 정도 피복하여 구출한 후, 스프링의 내외부에 절연고무를 몰딩한 스프링(2)으로 된 파형관을 전력량계의 전선위에 단자 안전카바를 덧 씌우고 단자 안전카바의 하부부분에 소형 케이블 타이(3)로 전선(1)과 안전카바(4)를 고정한다.The present invention covers the electric wire (1) to be connected to the electricity meter terminal by about 30mm and rescues it. Secure the wire (1) and safety cover (4) with a small cable tie (3) on the underside of the cover.
* 전력량계 단자 안전카바와 전선의 결선(전력량계 신설시)* Connection of power meter terminal safety cover and electric wire (when new electricity meter is installed)
전력량계 단자대 나사를 푼 후, 단자 안전카바 상부를 리드선 인입, 인출구에 밀착시키고 전선부분을 위로 밀어 올리면 단자 안전카바는 단자대에 걸리면서 압축되고 구출된 전선만 단자내로 삽입될 때 나사를 조여서 결선을 완료한다.After unscrewing the electricity meter terminal block screw, if the upper part of the terminal safety cover is in close contact with the lead wire inlet / outlet and push up the wire part, the terminal safety cover gets caught in the terminal block. When only compressed and rescued wires are inserted into the terminals, tighten the screws to complete the wiring.
* 전력량계 노후 및 고장으로 철거와 교체* Demolition and replacement due to aging and failure of electricity meter
전력량계의 철거 및 교체시에는 인,출입 전선(피복선)을 손으로 잡고 전력량계 단자대 나사를 풀면 스프링 압축이 풀리면서 심선이 안전카바 속으로 들어가 완전 절연이 유지된다.When dismantling and replacing the electricity meter, hold the lead wire and lead wire (coated wire) by hand, and unscrew the electricity meter terminal block screw, the spring will be decompressed and the core wire will go into the safety cover to maintain complete insulation.
전력량계 결선작업시 고안된 안전카바를 사용함으로써 계기업무에 종사하는 작업원이 작업시 활선부분에 접촉되지 않도록 방호하여 감전 또는 선간접촉시 화상사고를 예방할수 있다.By using the safety cover designed for the power meter connection work, the worker in the instrument work is protected from being touched by the live line, and it is possible to prevent burns in case of electric shock or line contact.
