Description

Technical Field

[0001] The utility model relates to the technical field of three-phase electric meters, in particular to a three-phase electric meter which is easy to assemble and disassemble. Background Art

[0002] Three-phase electricity meters are mainly used to measure electric energy. They can measure the power of single-phase AC power and convert it into a unified standard form. Since three-phase electricity meters need to be connected to external wires, they are generally equipped with wire holes so that cables can be inserted through the wire holes to facilitate wiring.

[0003] When wiring three-phase electricity meters on the market, the inner core of the cable is inserted into the corresponding copper socket, and then the inner core is pressed against the copper socket with a tightening screw to complete the connection operation. Due to the large number of connected cables, the staff needs to perform multiple wiring and screw tightening operations. This operation process is relatively cumbersome. Each disassembly and assembly requires multiple screw tightening and loosening operations. It is not possible to install multiple cables in a modular manner and then perform unified wiring operations. This will bring inconvenience to the disassembly and assembly operations and affect the use effect. In view of this, we propose a three-phase electricity meter that is easy to disassemble and assemble. Utility Model Content
