Description

technical field

[0001] The invention relates to a high-voltage metering integrated power distribution device used in power distribution networks, in particular to an intelligent monitoring device for high-voltage electric energy. Background technique

[0002] At present, most of the electric energy metering integrated distribution devices used in the power supply and distribution system are low-voltage metering integrated distribution devices designed and manufactured by traditional manual meter reading methods. In the actual operation of the low-voltage metering integrated distribution device, there are certain irrationality, for example, the no-load power loss of distribution transformers is calculated into the actual power consumption of power consumers by using artificially estimated values. Dispute with electricity supply department. Also because the existing high and low voltage metering devices do not have the remote automatic control function, there are certain defe...
