Description

Technical Field

[0001] This utility model relates to the field of power metering equipment technology, and in particular to a metering junction box adapter. Background Technology

[0002] The metering junction box (also known as the power metering junction box) is the core component of the secondary circuit of the power metering device. It is mainly used to connect the secondary wires of the voltage transformer (PT) and current transformer (CT) to the power meter after wiring distribution (or wiring convergence) through their terminals, so as to achieve accurate measurement of power.

[0003] During long-term operation, the internal components of an electricity meter may develop measurement errors due to aging and other factors, thus requiring periodic replacement of the meters in use. When replacing an electricity meter, the old meter must be removed from the metering junction box, and the new meter installed. This process inevitably requires disconnecting the meter's wiring, leading to power outages and affecting the normal operation of downstream electrical equipment.

[0004] Therefore, how to provide a metering junction box adapter to effectively transfer metering junction boxes, thereby improving the seamless replacement of electricity meters and ensuring the continuity of power supply, has become an urgent technical problem to be solved.
