同时也考虑了变压器分接头对中低压侧电压的调整。

Voltage adjustment by transformer taps at medium_low voltage supply are also considered.

为此，提出了一种基于CAN总线的分布式中低压母线保护方案。

In view of that, this paper puts forward a kind of distributed middle voltage busbar protection scheme based CAN bus.

Let's say we start from some V1 and p1 here, so high pressure, small volume and we end up with a high volume low pressure, under constant temperature condition.

例如我们要从压强比较高，体积比较小V1，p1出发,到达低压强，大体积的末态，过程中温度不变。
