住宅小区供电变压器超负荷能力的核定

住宅小区的变压器在春秋两个季节里，供电量不足额定容量；而夏冬两个季节，出现容量严重不足，造成变压器过负荷保护的装置经常跳闸，使小区内的居民生活受到影响。通过对小区供电变压器负荷的调查和对变压器保护的分析，变压器在大部分时段里的工作条件和设计计算使用的条件有较大差别。在不影响整体产品使用寿命的前提下，调整其允许输出能力不失为解决问题的一种方法。

Over-load Ability Cognizance of Residential Quarters Transformer

In autumn and spring, the power supply of the residential quarters transformer can not reach the rating, but in Summer and winter, because of abnormal weather, air-conditioner and heating-machine are used sweepingly, so, the power supply is in serious shortage, as a result, the transformer over-load protective device usually turn off, the residential quarters dweller's life suffers a lot. By the investigation of transformer load and analysis of the transformer protection, there are many differences between the working condition of transformer in most period of time and the condition in design and calculation. At premise that does not affect the whole production's using life-span, to adjust its output capacity is also a solution.
