Fast development, power information acquisition terminal are also used widely.Electric energy meter and power information acquisition terminal use series wiring
Mode adds reactive energy-meter joint connection identical, still continues to use traditional two-stage metering device with traditional active electric energy meter
Series-connected terminal box.Since function is not powerful enough in terms of measurement loop status monitoring for electric energy meter and power information acquisition terminal, meter
Amount circuit is broken down and cannot be discovered and ruled out in time, and electric energy meter counts electric flux less, causes power supply unit huge economic losses, supplies
Electric unit promotes and applies loop state logging intentionally.On the basis of electric energy meter and power information acquisition terminal joint wiring,
Install loop state logging additional again, existing two-stage metering device series-connected terminal box can no longer meet application, can only use two
Two-stage metering device series-connected terminal box joint wiring, or largely carry out wire jumper and connection using fly line, when carrying out electric energy performance
When field tests or changes table, each electrical equipment cisco unity malfunction of metering units.
Summary of the invention
To solve the above-mentioned problems, the invention proposes a kind of new solution, there is the series connection of three-level metering device
Line and scene series connection verifying function.It is characterized in that by wiring copper post, crimping bolt, wire jumper, insulator foot, transparent upper cover group
At accessing the electric energy meter of this terminal box, use suitable for phase three-wire three or the metering device secondary circuit of three-phase and four-line power supply system
Power information acquisition terminal, loop state logging three-level metering device are adopted and are connected serially, by the combination settings of wire jumper,
Electric energy meter, power information acquisition terminal, loop state logging three-level metering device UVW three-phase voltage can be controlled separately, electricity
Electric energy meter+power information acquisition terminal, electric energy meter+loop state logging, electric energy can also may be implemented with independent operating in energy table
Table+power information acquisition terminal+loop state logging combined running mode replaces power information acquisition terminal or circuit shape
When state logging, electric energy meter metering is not influenced, and there is series connection calibration connection function, when carrying out electric energy meter field test or changing table,
It does not influence each electrical equipment of metering units to work normally, upper cover screw tightening with holes can install seal additional, have thief-proof electric work
Energy.
