這時(shí)去右旋“電壓調節”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(shuō)明電源工作在恒流狀態(tài)，這時(shí)的輸出電壓也不是“調”出來(lái)的，而是由負載決定的。只有去調節“電流調節”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，FLN4234A中文PDF使用手冊總之，要弄清主從關(guān)系。電源處于“恒流”狀態(tài)時(shí)去調電流，處于“恒壓”狀態(tài)時(shí)去調電壓，才能改變負載上的電壓和電流。本套岸電系統在碼頭前沿的電纜接電箱和電纜卷盤(pán)車(chē)的設計上都運用了國內首創(chuàng )的防爆型設計，防爆等級為IIBT4，實(shí)際大部分設備防爆等級達到了IIBT6，符合GB3836.1-2000《爆炸性氣體環(huán)境用電氣設備 第1部分：通用標準》要求，較傳統岸電系統更加安全可靠，符合?；a頭接岸電需求。本系統核心部分變頻電源為2套森蘭SB70P系列變頻電源，單臺容量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年成熟低壓平臺技術(shù)的基礎上，針對岸電電源應用需求特點(diǎn)定制開(kāi)發(fā)的新一代高性能變頻電源，具有動(dòng)態(tài)響應快，過(guò)載能力強，控制精度高等優(yōu)點(diǎn)，無(wú)論是系統拓撲結構選擇，控制性能，還是散熱系統設計，都首屈一指。具有以下特點(diǎn)：
1) 拓撲結構：前端采用12脈沖整流，中間環(huán)節采用共直流母線(xiàn)，輸出采用LCL濾波器，高載波頻率，輸出電能質(zhì)量更好；
2) 采用模塊化并聯(lián)冗余設計，維護方便，可靠性高；
3) 針對岸電電源工作特點(diǎn)，在岸電電源高壓側有防勵磁涌流限流功能，當沒(méi)有連船時(shí)，系統損耗接近等于零。當需要連船時(shí)，合高壓瞬間，沒(méi)有涌流發(fā)生，合閘次數不受限制；
4) 內部通訊網(wǎng)絡(luò )采用光纖網(wǎng)絡(luò )，通訊傳輸速度快，抗干擾能力強；
5) 可后期擴容，多臺岸電系統之間通過(guò)光纖通訊連接，通過(guò)岸電控制系統和輸出同步追蹤鎖相技術(shù)實(shí)現功率均衡、負荷均衡、同步協(xié)調控制，完美解決系統后期擴容的需求。系統輸出容量不足時(shí)可自動(dòng)并網(wǎng)擴容，容量有余時(shí)自動(dòng)切除，單臺故障時(shí)自動(dòng)切除降額，整個(gè)系統擴容后其性能參數不會(huì )降低；
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
