我县南桥变电所,电压35千伏,总容量为4,800千伏安,负担着半个县的电力供应。去年,它的最高负荷为总容量的89%。今年5月,最高负荷已达总容量的94%,以后负荷仍在继续增加。据当时预计,今年将要超载主变容量的22%左右,如不立即采取有效措施,将会影响生产用电需要。为此,我们从调查研究着手,分析了内部资料并进行负荷实测,发现目前农灌用电的负荷规律是:每天 My county’s Nanqiao Substation has a voltage of 35 kilovolts and a total capacity of 4,800 kVA, which is responsible for the electricity supply in half of the counties. Last year, its highest load was 89% of its total capacity. In May of this year, the maximum load has reached 94% of the total capacity, and the load continues to increase thereafter. According to estimates at that time, about 22% of the capacity of the main transformer will be overloaded this year. If no effective measures are taken immediately, it will affect the demand for electricity for production. To this end, we started with investigations and studies, analyzed internal data and conducted load measurements, and found that the current load of electricity for agricultural irrigation is:
