B, single screw pump before adding buffer tank in pipeline, the buffering can store a certain amount of crude oil, and a current limiting device for mixture pumps supply a certain amount of crude oil.
单螺杆泵前管路中增设缓冲罐，在缓冲罐里储存一定量的原油，并用一套限流装置给混输泵供给一定量的原油。
If high voltage is used, current limiting resistors are needed to avoid damage to the current switches in case the device under test breaks down.
如果使用高压，则需要利用限流电阻，以免被测装置击穿后损坏电流开关。
The invention relates to an electrical current limiting device having a superconductive switching element.
本发明涉及一种具有超导开关元件的电流限流装置。
