重慶貨梯變壓器本身的運行也是一種耗能，就10KV配電網來說有一部分電能就被電力變壓器所消耗。由于變壓器使用量大、運行時間長，在選擇和使用上存在著巨大的節能潛力，因此為了降低能源損耗，杭州貨梯電力變壓器中使用了3個節能技術。Hangzhou cargo transformer itself is a kind of energy consumption, on the 10KV distribution network, there is a part of the power consumed by the power transformer. Due to the large use of transformer, long running time, there is a huge potential for energy saving in the selection and use, so in order to reduce energy losses, Hangzhou cargo ladder power transformer using 3 energy-saving technologies.

1.理想運行負載：通常情況下，重慶貨梯電力變壓器運行的負載在60～70Se左右比較理想，此時變壓器損耗較小，運行費用較低。Ideal operating load: normally, the Hangzhou cargo ladder power transformer operating load in the 60 ~ 70Se is relatively ideal, at this time the transformer loss is small, the operating cost is low.

2.理想功率因數：提高重慶貨梯電網的功率因數，有利于電力變壓器的經濟運行。Ideal power factor: to improve the power factor of Hangzhou cargo ladder, it is good for the economic operation of power transformer.

3.降低重慶貨梯電力變壓器運行溫度：電力變壓器的溫升每超過8℃，壽命將減少一半。如果它的運行溫度超過變壓器繞組絕緣允許的范圍，絕緣迅速老化，甚至使繞組擊穿，燒毀變壓器。Reduce the operating temperature of Hangzhou cargo ladder power transformer: the power transformer temperature rise of more than 8 degrees Celsius, life expectancy will be reduced by half. If its operating temperature exceeds the range of the transformer winding insulation, the insulation is rapidly aging, and even makes the winding breakdown, burning the transformer.
