Automatic switch operation control system based on at89c 51的刀閘自動操作控制系統(tǒng)
Analogue switching operation order system of electric equipment 模擬式電氣設備倒閘操作票系統(tǒng)
Hook bars for disconnecting switch operation 隔離開關操作用鉤桿
The perioperative nursing care for the neonates undergone the arterial switch operation 新生兒大動脈轉(zhuǎn)位術的圍術期護理
Formatting accurate operation orders is the premise and key for correct switching operation as well asthe guarantee for steady performance of substations and power system 開列正確的操作票是正確倒閘操作的前提和關鍵,也是變電站及電力系統(tǒng)安全穩(wěn)定運行的保證。
The signal strength necessary for the switching operation and thus the switching point can be adjusted precisely via adjustments in the electronics ; in principle the switching and reset point can be adjusted separately 開關操作所需的信號強度換句話說開關點可以通過電子調(diào)節(jié)器精確校準開關點和復位點可以分別進行調(diào)較。
In addition to performing switch operations that involve partitioned tables , alter table can be used to change the state of the columns , constraints , and triggers of a partitioned table just like it is used for nonpartitioned tables 除了執(zhí)行涉及到已分區(qū)表的switch操作外, alter table還可用于更改已分區(qū)表的列、約束和觸發(fā)器的狀態(tài),就像它用于非分區(qū)表一樣。
3 . many transient interference waveforms are measured and recorded during switching operations in three 500kv - substations . these waveforms are analyzed , and the characteristic parameters are summarized in this paper based on statistics analysis 3 、參與了三座500kv變電站瞬態(tài)電磁環(huán)境的測量工作,獲得了變電站開關操作時產(chǎn)生的瞬態(tài)電場、瞬態(tài)磁場和瞬態(tài)電壓等數(shù)據(jù)。
The digital signals exchange between main station and substations , which is advantageous because it need not convert - knife switch operation . the system is more perfect than others . it integrates with making out an invoice , try outing and operation 各變電站與主控站可進行雙向數(shù)字通訊,不必在倒閘操作過程中,因修改操作或新增操作任務而往返站與站之間,方便快捷。
The practice proved : the system sets out from the running manage and locale operation of non - attended substation . its working - flow answers for regulation . it demonstrates the runner in convert - knife switch operation 實際應用證明:該系統(tǒng)從無人值守變電站的運行管理工作及其現(xiàn)場操作實際出發(fā),其工作流程完全按部頒“五防”的要求,對運行人員的倒閘操作起到了規(guī)范的作用。
