8106-TI-RT通用電氣模塊外形纖薄，體積小巧，導軌占用寬度僅39毫米，斷電保持時間達33ms，MTBF（平均無故障時間）值長達1720kh，為BMS設(shè)備的安全、穩(wěn)定、長期運行提供了可靠的電力保障。于該集裝箱式儲能系統(tǒng)的應(yīng)用地點多為偏遠地區(qū)，道阻且長，為防止運輸途中安裝松動甚至脫落的情況發(fā)生，箱內(nèi)設(shè)備都需要通過嚴苛的抗振測試。方案中的兩款普爾世電源均通過測試且表現(xiàn)優(yōu)異，這樣的優(yōu)勢能夠保障安裝一次完成且無后續(xù)問題，真正做到“安裝它，忘記它”。
8106-TI-RT通用電氣模塊深入細節(jié)的高可靠性也是普爾世成功的關(guān)鍵原因之一。隨著電力電子技術(shù)的發(fā)展和創(chuàng)新，使得開關(guān)電源技術(shù)也在不斷地創(chuàng)新。目前，開關(guān)電源以小型、輕量和高效率的特點被廣泛應(yīng)用幾乎所有的電子設(shè)備，是當今電子信息產(chǎn)業(yè)飛速發(fā)展不可缺少的一種電源方式。開關(guān)電源是利用現(xiàn)代電力電子技術(shù)，控制開關(guān)管開通和關(guān)斷的時間比率，維持穩(wěn)定輸出電壓的一種電源，開關(guān)電源一般由脈沖寬度調(diào)制控制IC和MOSFET構(gòu)成。開關(guān)電源是相對線性電源說的，其輸入端直接將交流電整流變成直流電，再在高頻震蕩電路的作用下，用開關(guān)管控制電流的通斷，形成高頻脈沖電流。在電感的幫助下，輸出穩(wěn)定的低壓直流電。
開關(guān)電源一般由脈沖寬度調(diào)制控制IC和MOSFET構(gòu)成。隨著隨著電力電子技術(shù)的發(fā)展和創(chuàng)新，目前開關(guān)電源主要以小型、輕量和高效率的特點被廣泛應(yīng)用到幾乎所有的電子設(shè)備，其重要性可見一斑。
根據(jù)開關(guān)器件在電路中連接的方式，開關(guān)電源總的來說可分為串聯(lián)式開關(guān)電源、并聯(lián)式開關(guān)電源、變壓器式開關(guān)電源等三大類。其中，變壓器式開關(guān)電源還可以進一步分成：推挽式、半橋式、全橋式等多種。根據(jù)變壓器的激勵和輸出電壓的相位，又可以分成：正激式、反激式、單激式和雙激式等多種。
那么開關(guān)電源和普通電源有什么區(qū)別，小編舉例予以以下論述。
普通的電源一般指的是是線性電源，是調(diào)整管工作在線性狀態(tài)下的電源。而在開關(guān)電源中則不一樣，開關(guān)管是工作在開、關(guān)兩種狀態(tài)下的：開 —— 電阻很小，關(guān) —— 電阻很大。開關(guān)電源是一種比較新型的電源，具有效率高、重量輕、可升、降壓、輸出功率大等優(yōu)點。但是由于電路工作在開關(guān)狀態(tài)，所以噪聲比較大。
system (such as CPU power supply, i/o power supply), etc. For the power supply for PLC system, we use the power supply with good isolation performance. 2. Cable laying in order to reduce the electromagnetic interference radiated by power cables, we choose shielded cables. In the project, the use of copper tape armored shielded power cable can greatly reduce the electromagnetic interference generated by the power line, and make the project achieve satisfactory results. Different types of signals are transmitted by different cables. The signal cables should be laid layer by layer according to the type of transmitted signals. It is strictly forbidden to use different conductors of the same cable to transmit power supply and signals at the same time; Avoid laying the signal line and power cable close to and parallel to reduce electromagnetic interference.
3. Conclusion and effect our modified circuit is simple, reliable and easy to maintain. Since it was put into use in June 2004, the fault rate of the modified circuit of the two bridge cranes has been zero, which saves a lot of human and material resources, reduces labor intensity, and saves tens of thousands of yuan of material consumption every year, solving a major problem of frequent electrical failures of asphalt bridge cranes for many years. Container yard bridge is one of the commonly used
