例句與造句

1. the tap-changer is made with solid state relay as its working mechanism and controlled by microprocessor . this switch has totally cancelled the mechanical drive organization, by the microprocessor according to the voltage of second side microprocessor decide the working condition of solid state rely, high regulation speed, need not transition resistor, rush current is low . operating frequently; there is no electric arc to produce, can put in the fuel tank of the voltage transformer directly; the structure is simple, the fabrication cost is low, benefit and use widely among the voltages transformer of distribution
   其中的有載調(diào)壓分接開關(guān)，它是一種完全由固態(tài)繼電器作為分接開關(guān)執(zhí)行機(jī)構(gòu)，由單片機(jī)控制的有載自動調(diào)壓的變壓器分接開關(guān)。該開關(guān)完全取消了機(jī)械傳動機(jī)構(gòu)，由單片機(jī)根據(jù)變壓器二次側(cè)電壓的高低，決定與變壓器各分接頭聯(lián)接的固態(tài)繼電器的工作狀態(tài)。調(diào)節(jié)速度快，改變分接頭時不需過渡電阻，沖擊電流小，可頻繁操作；無電弧產(chǎn)生，可以直接放在變壓器油箱中；結(jié)構(gòu)簡單，造價低，便于在配電變壓器中推廣使用。
2. It's difficult to find transition resistor in a sentence. 用transition resistor造句挺難的
