Problems solved by technology
[0003] The most common problem when using the existing three-phase electric energy meter is that after the main line is connected, the number of branch lines is large, which makes the internal temperature of the three-phase electric energy meter rise abnormally during the use process. The failure of the line causes a short circuit of

The invention relates to the technical field of three-phase electric energy meters, and discloses a three-phase electric energy meter modular disconnection system and a disconnection method thereof, the system comprises a bidirectional wiring mechanism, and the top of the bidirectional wiring mechanism is detachably connected with a bus connection structure. When each external plug on the bidirectional wiring mechanism is powered on and a pressing rod is pushed inwards, the pressing rod drives a push block in a sleeve to extrude a push spring in the sleeve, at the moment, a reset rod moves towards a displacement block, after the reset rod is in contact with the two extrusion blocks, the two extrusion blocks move in the opposite directions, and at the moment, a sliding block restores to the original position, the vertical rod straightens the third memory metal, the distance between the two insulating blocks is reduced, so that the distance between the sliding seats driven by the two connecting strips is gradually increased, the length between the second memory metal and the first memory metal is increased, and when a metal sheet is connected with an external plug, energization can be quickly recovered, therefore, not only can the safety of equipment and the safety of a circuit be protected, but also the circuit can be quickly recovered after each fault.
Description
technical field [0001] The invention relates to the technical field of three-phase electric energy meters, in particular to a three-phase electric energy meter modular disconnection system and a disconnection method thereof. Background technique [0002] The three-phase watt-hour meter is mainly a three-phase four-wire active and reactive watt-hour meter. The electromagnetic element is a separate structure, and the voltage movement adopts a closed sample movement made of the whole punch. The rotating system is calibrated by static balance, and its bearing is Double jewel structure with anti-vibration spring, the damping element is made of AlCo 34 magnetic steel, and the thermomagnetic alloy sheet is used for temperature compensation. The watt-hour meter is generated by the synthesis of voltage and current components-moving into the magnetic field, so that the disk rotates under its action, and the rotation speed of the disk is proportional to the size of the loadable current...
