Terminal block for electricity meter in order to protect wrong wire connection between electricity meter and MOF, and System for protecting wrong wire connection using the same

摘要

The present invention can prevent erroneous wiring when connecting the secondary terminal of the transformer of the instrument to the wattmeter, and the wattmeter terminal block for the prevention of erroneous wiring of the meter and the transformer of the instrument which is easy to use and has a simple structure. It relates to a miswiring prevention system. To this end, the present invention is a wattmeter terminal block coupled to the wattmeter in order to prevent incorrect wiring of the transformer and meter for the meter, the wattmeter terminal block is formed of a first terminal housing and the first terminal housing and extending A first terminal socket provided in the second terminal housing for coupling with a two-terminal housing, a connection connecting unit for connecting the instrument transformer and the electricity meter, and installed in the first terminal housing to connect with the electricity meter; A first connection terminal, a second connection terminal installed in the first terminal housing and connected to the first connection terminal, a first socket terminal and the second connection terminal provided in the first terminal socket. An electrical connection member for electrically connecting the plurality of first contacts to be fitted to the connection connection unit at one time; The first socket main body having a quick matching member, and the first socket coupling frame is installed while surrounding the first socket body for coupling with the connection connection unit to prevent the miswiring of the electricity meter and instrument transformer Provided is a terminal block for a power meter for the same and an anti-wiring system using the same.
