비교계량가능한 고압고객 전력량계용 무정전 교체단자대{Terminal Blocks With Comparative Measure}Terminal Blocks With Comparative Measure for Uninterruptible High Voltage Power Meters

본 발명은 한국전력공사에서 공장같은 대량의 전력사용가들의 전력량을 측정하는데 사용되는 전력량계의 보조기기인 무정전 교체단자대에 관한 것으로, 교체단자대의 구조적한계로 불가했던 2대의 계량기 비교측정이 가능하도록 하였다.The present invention relates to an uninterruptible replacement terminal, which is an auxiliary device of a wattmeter used to measure the amount of power of a large amount of power users such as factories in Korea Electric Power Corporation.

현재 고압을 사용하고있는 수용가들은 무정전 교체단자대와 전력량계를 결합하여 전력량을 측정하고있다. 교체단자대는 전력량계 점검이나 고장으로 교체시에 무정전으로 간단하고 안전하게 작업이 이루어지도록 도와주는 반드시 설치해야 하는 필수장비이다.Customers using high voltage now measure the amount of electricity by combining an uninterruptible replacement terminal and a meter. The replacement terminal block is an essential equipment that must be installed to help ensure that the operation is simple and safe in the event of a power meter check or replacement due to an uninterruptible power failure.

기존 교체단자대는 전력량계와의 결합시 오결선을 방지하고 간편하게 설치가 이루어지도록 도와주지만, 고압 수용가가 전력량계 이상이나 고장이유로 부과되는 요금에 의문을 가질때나 한국전력에서 전력량측정을 재확인할 필요성을 느낄때 검증을 위하여 전력량계 2대를 같이 설치하여 비교검증하고 싶어도 비교계량기로 배선할 단자가 없고 구조도 변경이 불가능해 비교계량을 할 수 없다.Existing replacement terminal block prevents incorrect wiring when combined with electricity meter and helps to install easily, but when high voltage consumer has doubt about electricity meter or charges due to failure, or when it feels the need to reconfirm electricity measurement in KEPCO For verification, even if two power meters are installed together for comparison and verification, there is no terminal to be wired with the comparator and the structure cannot be changed.

따라서 이런 단점을 해결할 새로운 단자대가 필요하다.Therefore, a new terminal block is needed to solve this disadvantage.

본 발명은 기존 무정전 교체단자대가 할 수 없었던 전력량계 2대를 같이 설치하여 비교계량이 가능하도록 하는 교체단자대를 제공하는데 목적이 있다.It is an object of the present invention to provide a replacement terminal that can be installed by comparing two meters of electricity meters that could not be the existing uninterruptible replacement terminal.

본 발명은 무정전 교체단자대에 있어서 전압단자를 단락시킬 연결편을 가지고 전압단자는 보조단자대와 결선하여 다른 교체단자대와 배선 가능하도록 한다. 전력량계를 거처서 나오는 3L, 2L, 1L 전류 배선단자를 추가로 하나더 만들고, P0전압과 접지하기위한 접지바는 필요시 외부에서 쉽게 해체 가능한 구조로 한다.The present invention has a connection piece for shorting the voltage terminal in the uninterruptible replacement terminal block, the voltage terminal is connected to the auxiliary terminal block to enable wiring with other replacement terminal block. Make another 3L, 2L, 1L current wiring terminal through the electricity meter, and the ground bar for P0 voltage and ground should be easily disassembled from the outside when necessary.

본 발명은 기존 교체단자대가 하지못하는 전력량계 2대의 동시 비교계량이 가능하도록 했으며 배선이 단순하고 직관적이어서 오결선가능성이 낮고 안전한 결선이 가능하다.The present invention enables the simultaneous comparison of two power meters that the existing replacement terminal can not do, and wiring is simple and intuitive, so that there is a low possibility of incorrect wiring and a safe connection is possible.
