Embodiment Construction
[0015] A connection terminal for a large-load direct-in type three-phase watt-hour meter of the present invention includes a wire connecting part 2 and a meter-tail connecting part 1 of the watt-hour meter. Sure. And the meter tail connection part 1 is a flat structure, the wire connection part 2 is made of aluminum or copper, the meter tail connection part 1 is made of copper, and the terminal is covered with an insulating layer. The insulating layer is preferably a silicone sleeve. The wire connection part 2 of the terminal used when the aluminum wire is connected to the ammeter is made of aluminum, while the wire connection part 2 is made of copper when the copper wire is connected to the ammeter. The wire is crimped in the wire connection part 2, and the meter tail connection part 1 is stretched into the meter tail hole and pressed tightly with the meter tail screw.
[0016] In this embodiment, a preferred structure of the connection terminal is given. The flat structure ...

Description
technical field [0001] The invention relates to a connection terminal, in particular to a connection terminal for a large-load direct-in three-phase watt-hour meter. Background technique [0002] Terminal blocks are widely used in power systems, and there are many varieties. They are mainly used for the connection between wires, cables, and electrical equipment. According to their materials, they are divided into copper, aluminum, copper-aluminum, and alloys. The current-carrying capacity and mechanical strength of the terminal connection should be as close as possible to that of the original conductors and electrical equipment, or not much different, so as to ensure the safe, reliable and efficient operation of conductors and electrical equipment. Terminal blocks also need to meet the requirements of easy disassembly as much as possible. [0003] At present, the rated current of the in-line three-phase watt-hour meter provided by the power supply company is 80A, the diamet...
