Abstract

The invention discloses a photovoltaic energy storage and power supply intelligent terminal system of an agricultural drainage transformer. The system comprises a dual-power automatic switching device, two power supplies which are respectively connected to an electric energy input port of the dual-power automatic switching device, an electric energy output line which is electrically connected to an electric energy output port of the dual-power automatic switching device, and an electric energy meter connected to the electric energy output line. The two power supplies are respectively a photovoltaic power supply system and a power distribution network power supply system. the operation of power distribution equipment without power on a line is reduced, the no-load loss of the equipment is reduced, the power supply reliability of the line is improved, and the complaint risks and severe weather accident risks caused by frequent power failure are prevented; no matter the power distributionnetwork is electrified or powered off, 24-hour uninterrupted on-line monitoring of electric meter data can be realized.

Description

technical field [0001] The invention relates to the technical field of distribution network electric power construction, in particular to an intelligent terminal system for photovoltaic energy storage and power supply of agricultural row transformers. Background technique [0002] my country's agricultural planting area is extensive, and it is necessary to configure agricultural row transformers to provide power supply for agricultural production. Due to the characteristics of agricultural production, a large number of existing agricultural row transformers operate at no-load or light load, and the no-load time is relatively long. The effective use time of agricultural row transformers in northern agricultural planting areas is only about 3 months, and the remaining 9 months are basically In the no-load state, the no-load loss is serious. [0003] Due to the dense layout of most agricultural terrace areas, frequent switching and switching of electricity, small power consump...
