重庆货梯变压器本身的运行也是一种耗能，就10KV配电网来说有一部分电能就被电力变压器所消耗。由于变压器使用量大、运行时间长，在选择和使用上存在着巨大的节能潜力，因此为了降低能源损耗，杭州货梯电力变压器中使用了3个节能技术。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.理想运行负载：通常情况下，重庆货梯电力变压器运行的负载在60～70Se左右比较理想，此时变压器损耗较小，运行费用较低。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.理想功率因数：提高重庆货梯电网的功率因数，有利于电力变压器的经济运行。Ideal power factor: to improve the power factor of Hangzhou cargo ladder, it is good for the economic operation of power transformer.

3.降低重庆货梯电力变压器运行温度：电力变压器的温升每超过8℃，寿命将减少一半。如果它的运行温度超过变压器绕组绝缘允许的范围，绝缘迅速老化，甚至使绕组击穿，烧毁变压器。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.
