Abstract

The invention relates to a metering device solar uninterrupted standby power supply. The structure of the metering device solar uninterrupted standby power supply is that a solar cell panel is connected with a storage cell through a rectifier. The storage cell is connected with an inverter transformer which is connected with electricity utilization equipment through an automatic switching device. A transformer power supply is connected with the automatic switching device. The solar cell panel is used as energy and power is supplied to the storage cell through a rectification and voltage stabilizing system, and then power is supplied to the inverter transformer by the storage cell. According to the metering device solar uninterrupted standby power supply, automatic switching can be realized, time-interval control can be realized, and the metering device uninterrupted power supply product can be realized through the natural conditions.

Description

technical field [0001] The invention relates to a backup power supply device, in particular to a solar uninterrupted backup power supply for a metering device. Background technique [0002] In some areas dominated by agricultural production, seasonal electricity users, paddy fields, and electric wells account for a large proportion of special variable users. The user often disconnects the power supply of the transformer when there is no electricity, causing the metering device to be powered off. The power supply department cannot realize the data recall of the electric energy metering device, cannot grasp the status of the on-site metering device, and cannot judge whether the metering device is faulty for metering device maintenance. . Contents of the invention [0003] The present invention aims at the above-mentioned problems in the prior art, and provides a solar energy uninterruptible backup power supply of a metering device with a high utilization rate, so as to solv...
