switch-off delay 中文意思是什麼
switch-off delay
解釋
斷開延遲-
The automatic switch has light function ( delay time for three minutes ) : the light is opened automatically while opening the door, shut off the door taillight to go out automatically
動開關照明燈功能（延時三分鐘） ：開門時燈自動打開，關閉門后燈自動熄滅 -
On the one hand, the receiver must be self - adaptive to set as fast as possible the " 0 " and " 1 " bit level judgement threshold in a dynamic way ; on the other hand, the transmitter of onu should take some measures to minimize and compensate for the burst delay. the optical burst transmission circuit is thus required to switch on and off the laser in a snappy way to ensure fast signal sending. in that sense, the laser must be designed with a superb response speed
一方面，接收機必須具有自適應功能，能以最快的速度動態調定" 0 " 、 " 1 "比特電平判決門限；另一方面， onu的發射機應該採取-定的措施減小和補償突發時延，其光突發發送電路要求能夠非常快速地開啟和關斷激光器，迅速發送信號，所以，它需要使用響應速度很快的激光器。 -
It emphases the selection of secondary voltage of the step - down transformer, the control and protection of thyristor, the calculation of compensation capability and group capability, the technique of cross - zero switched on / off capacitors or reactor, the solution of avoiding possible resonance in switching on / off groups of capacitors or reactor and the measure of the best time to switch ( including the design of the computer survey and control system, instrument deliver system, delay operate and protect system ). although thyristor as a no - contact switch can avoid almost the problem of contact switch with contact, it can not solve the over - voltage, over - current and transient process itself as switching on / off capacitors or reactor. so we must develop a set of thyristor - switched control and protect system with great reliability so that it can realize of cross - zero switching on / off capacitors or reactor at any time
晶閘管具有過零、動作快速的特點，本研究以晶閘管為電容器和電抗器的分組投切開關，重點研究了協調變壓器二次電壓的選擇、晶閘管觸發控制及保護、動態補償容量及分組容量的計算確定、過零投切電容器和電抗器技術的實現、以及分組投切電容器和電抗器可能發生諧振的處理計算方法，給出實現最佳補償投切選擇方法（測控系統、儀表變送系統、操作和保護系統的設計步驟） ，研製了一套高可靠性晶閘管觸發控制及保護系統，實現對無功的靜止可調補償。 -
Put through power supply, open lamp switch treat one minute, start up fan switch 2 - 3 minutes and then proceed job, work stop turn off lamp switch delay 3 - 5 minutes lamp complete cool off later and then turn off fan
接通電源后，打開燈開關待1分鐘后，啟動風機開關2 - 3分鐘后即可進行工作，工作停止后關掉燈的開關延時3 - 5分鐘燈完全冷卻后即可關掉風機。 -
All the electric safe protection devices now being used function only one time protection when the equipment is out of order, i. e., they can ' t delay the on / off of 220v. once industrial equipment, household appliances and instruments and meters have troubles in mechanism or electronic elements because of overflow, overload, overheat or short circuit and furthermore, one time overheat switch can ' t start to function, there is no second protection device that will cut off the circuit timely, accurately and quickly, to protect the electric equipment
根據消防部門統計，我國目前電器引起火災屢見不鮮（見1999年8月31日上海文匯報第12版報導經消防部門統計，我國目前電器引發的火災，高居火災起因為第一位） ，如以相同用量相比，我國觸電導致死亡人數是發達國家幾十倍甚至上百倍，而且這類事故的發生很大程度是與劣質電器元件有關。
