Abstract
The invention provides a standard meter access-based uninterrupted-power replacement method for replacing electric energy meters. A standard meter is accessed to the circuit of an electric energy meter. During the process from the removal of an old electric energy meter to the installation of a new electric energy meter, an electric energy metering circuit is established through switching the short-circuit plates of an electric energy metering device. In this way, the electric energy metering function is realized during the replacement of electric energy meters by means of the standard meter. According to the technical scheme of the invention, the electric energy metering function is realized during the replacement of electric energy meters. In this way, the economic loss caused by the missed metering phenomenon of the electric energy during the current power-outage replacement process of electric energy meters in the prior art can be avoided. According to the method, a three-phase 0.02-level portable multifunctional standard electric energy meter is adopted, so that the metering accuracy can be ensured. At the same time, based on the design of upper blocks, lower blocks and short-circuit plates in the junction box of the electric energy metering device, the electric energy is completely cut off during the mounting and dismounting process of to-be-dismounted electric energy meters and newly mounted electric energy meters. Therefore, electric energy meters are isolated from the charged electric energy metering loop of the standard electric energy meter. As a result, the secure operation is realized.
Description
Technical field
