Problems solved by technology
[0017] 1. The above scheme 1 (CN207719034U) puts the regulating switch outside the transformer oil tank. Compared with putting the switch inside the oil tank, the ability of breaking the arc of the tap changer is reduced and the reliability is reduced.
[0018] 2. The above-mentioned scheme one and scheme two (CN207719034U and CN106952713A) do not have the technology of performing local intelligent operation or remote monitoring and remote control through the cloud control platform

The invention discloses an intelligent distribution device and method based on sensing low-voltage system parameters. If the voltage value of the secondary side collected by an acquisition module exceeds a set range, a controller issues a shift command, a motor-driven mechanism within an on-load capacity and voltage regulating tap switch is used to adjust the shunting tap of the transformer to achieve the purpose of voltage regulation, and the controller adjusts the capacity of the transformer according to the magnitude of the current of the secondary side of the transformer. The intelligent distribution device provided by the invention forms an on-load automatic capacity and voltage regulating power distribution system with the on-load capacity and voltage regulating tap switch and the capacity and voltage regulating transformer, so as to implement the load change requirements of customers. The on-load voltage regulating system can ensure that the voltage of the terminal user is stable within a required range and improve the quality of the power supply. The on-load capacity regulating system adjusts the power consumption of the transformer itself according to the load of the terminal user of the transformer to achieve the purpose of energy saving.
Description
technical field [0001] The invention relates to an intelligent distribution transformer device, in particular to an intelligent distribution transformer device and method based on sensing low-voltage system parameters. Background technique [0002] Due to the demand for heating in winter and cooling in summer, when electricity customers use electric heating and air conditioning at the same time, due to the characteristics of single-phase power supply, the low-voltage power distribution system has the following problems: [0003] The terminal voltage qualification rate is low: [0004] The actual voltage of the line deviates from the rated voltage as one of the important indicators of power quality. When the actual voltage deviates from the normal allowable fluctuation range, affected by the low voltage, the output of the power supply equipment is reduced, affecting the normal use of user equipment and reducing the economic benefits of the equipment. As far as the power supp...
