這時(shí)去右旋“電壓調(diào)節(jié)”旋鈕，輸出電壓是會(huì)升高，輸出電流也會(huì)隨之升高的。(電壓是主，電流是從)。同理，如果“恒流”燈亮，說明電源工作在恒流狀態(tài)，這時(shí)的輸出電壓也不是“調(diào)”出來的，而是由負(fù)載決定的。只有去調(diào)節(jié)“電流調(diào)節(jié)”旋鈕，輸出電流才會(huì)改變，輸出電壓也隨之變化。(這里電流是主，電壓是從)
CPU3680工控卡件，F(xiàn)LN4234A中文PDF使用手冊(cè)總之，要弄清主從關(guān)系。電源處于“恒流”狀態(tài)時(shí)去調(diào)電流，處于“恒壓”狀態(tài)時(shí)去調(diào)電壓，才能改變負(fù)載上的電壓和電流。本套岸電系統(tǒng)在碼頭前沿的電纜接電箱和電纜卷盤車的設(shè)計(jì)上都運(yùn)用了國(guó)內(nèi)首創(chuàng)的防爆型設(shè)計(jì)，防爆等級(jí)為IIBT4，實(shí)際大部分設(shè)備防爆等級(jí)達(dá)到了IIBT6，符合GB3836.1-2000《爆炸性氣體環(huán)境用電氣設(shè)備 第1部分：通用標(biāo)準(zhǔn)》要求，較傳統(tǒng)岸電系統(tǒng)更加安全可靠，符合危化碼頭接岸電需求。本系統(tǒng)核心部分變頻電源為2套森蘭SB70P系列變頻電源，單臺(tái)容量1MVA，采成直流共母排方案。SB70P系列低壓岸電變頻電源基于森蘭22年成熟低壓平臺(tái)技術(shù)的基礎(chǔ)上，針對(duì)岸電電源應(yīng)用需求特點(diǎn)定制開發(fā)的新一代高性能變頻電源，具有動(dòng)態(tài)響應(yīng)快，過載能力強(qiáng)，控制精度高等優(yōu)點(diǎn)，無論是系統(tǒng)拓?fù)浣Y(jié)構(gòu)選擇，控制性能，還是散熱系統(tǒng)設(shè)計(jì)，都首屈一指。具有以下特點(diǎn)：

It is difficult to wire underground and on the ground. Once the line is aging and broken, it is difficult to troubleshoot. A lot of time must be spent to deal with the line problem, so that the on-site temperature can not be monitored for a long time. The system uses the ho1zb module and pc2zb module of Haiwei to establish a wireless communication network. Under the condition that the on-site environment does not change, there will be no communication disconnection, and the line problem will be completely solved.
3. Using h32dt module, one module can monitor the temperature of 32 areas, with low cost; The module has its own broken line alarm, and the communication is stable; The module uses communication to read the data of DS18B20, and the digital chip determines the temperature with high accuracy. The module itself also has its own RS485 communication port. When the temperature measurement point is far from the host, the module can be used as a remote module to reduce wiring, which is conducive to measuring the temperature of many places in the coal mine. The coke discharging system is an important part of the coke dry quenching system, and it is another important process
