Abstract

The invention discloses a distribution transformer capacity control method, including a processor, an executive mechanism, a voltage regulation mechanism, a voltage sensor, a current sensor, a high-voltage electric control switch, an insurance module, a low-voltage electric control switch and a transformer; The processor is connected to the executive mechanism and the regulating mechanism in sequence, the regulating mechanism is connected to the high-voltage electric control switch and the low-voltage electric control switch in parallel, the high-voltage electric control switch is connected to the transformer, the processor is connected to the voltage sensor and the current The sensors are connected in series, and the voltage sensor and the current sensor are jointly connected with the insurance module and the transformer. In the whole process of this invention, the voltage is controlled intelligently and distributed in real time, which can realize the accurate control of the capacity of the distribution transformer, and the intelligent determination of the load calculation can not only meet the load demand, but also obtain high equipment utilization, thereby ensuring the power grid The rational use of resources and the safe operation of the power grid.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a method for controlling the capacity of a distribution transformer. Background technique [0002] With the continuous increase of user demand for electricity, the phenomenon of large-scale industrial expansion and installation of electricity is becoming more and more common. In the business expansion installation, the most important thing is how to reasonably select the capacity of the distribution transformer according to the actual needs of the power users. If the capacity is too large, it will increase the investment in equipment purchase, installation, operation and maintenance, and cause waste; on the contrary , it will cause the distribution transformer to overload, and the power demand and reliability will be difficult to meet. Therefore, practical coefficients are often used to guide the selection of transformer capacity and improve the utilization rate of equip...

Problems solved by technology

However, the current selection of practical coefficient values ​​is unreasonable, and there are mainly the following problems: the range of existing index values ​​is too wide, and there is insufficient guidance on how to select specific values ​​when calculating loads

Existing index values ​​cannot distinguish differences in regional development status, and the same practical coefficient values ​​are often used
