12P3162X162模塊,SLS1508使用進(jìn)展
動葉及變頻器禁止同時投入自動。MVe2變頻器輸入采用單相PWM整流、諧波極小，這樣使得輸入變壓器二次側(cè)繞組不需要移相，結(jié)構(gòu)變得簡單；同時采用三電平IGBT串聯(lián)輸出，提高了單元耐壓等級、減少了單元數(shù)量使得輸入變壓器二次側(cè)繞組數(shù)量大大減少、工藝更簡單可靠。MVe2變頻單元的硬件構(gòu)成整流：IGBT、逆變：IGBT為三菱原裝產(chǎn)品，中間直流回路電容：可自愈式金屬薄膜電容，使用壽命長。

2.6 緊急停機：變頻裝置自身帶有緊急停機按鈕。另外在電動機事故按鈕增加一對常開接點，接至變頻裝置用來在電動機故障時就地同時切除變頻裝置運行。
4 控制及邏輯說明
（1）變頻運行方式
正常運行期間兩臺一次風(fēng)機變頻自動運行，動葉手動放置在60～80%開度，通過變頻器自動調(diào)節(jié)風(fēng)機轉(zhuǎn)速，調(diào)整一次風(fēng)壓；
（2）工頻運行方式
兩臺風(fēng)機均工頻運行期間，保持原邏輯不變，通過調(diào)整風(fēng)機動葉自動調(diào)節(jié)一次風(fēng)壓；
（3）一臺變頻一臺工頻運行
1）變頻器投入自動調(diào)節(jié)一次風(fēng)壓，工頻運行風(fēng)機手動調(diào)節(jié)動葉開度，調(diào)整兩臺風(fēng)機出力平衡；
2）工頻運行風(fēng)機動葉投入自動調(diào)節(jié)一次風(fēng)壓，變頻運行風(fēng)機手動調(diào)節(jié)轉(zhuǎn)速，調(diào)整兩臺風(fēng)機出力平衡；
3）動葉及變頻器禁止同時投入自動。某水電站250/50/10t慢速雙梁單小車橋式起重機，主要用于電站水輪發(fā)電機組及其輔助系統(tǒng)設(shè)備的安裝、運行維護(hù)和檢修的吊裝任務(wù)，也用于電站建設(shè)期間設(shè)備安裝、檢修及一般裝卸作業(yè)。起重機整體按A3工作級別進(jìn)行設(shè)計， 起重機主要由橋架結(jié)構(gòu)、大車運行機構(gòu)、小車（分別含有起升和小車運行機構(gòu)）、電動葫蘆以及電氣設(shè)備五大部分及其附件組成。四機構(gòu)均采用施耐德ATV71變頻器進(jìn)行調(diào)速，全車采用PLC進(jìn)行控制。
management is naturally inaccessible.
2. If the model with management is confirmed, it is necessary to determine whether the management IP address is correct. The factory default management IP of gaonet industrial switch is 10.10.10.1.
If the IP address is manually modified, please log in to the industrial switch with the modified IP. If you forget after manual modification, please restore the factory IP to the default 10.10.10.1, or connect the serial port to enter the command background of the industrial switch to view the management IP information (we have sent the operation manual before for specific operation, which can be operated according to the instructions in the manual). After confirming the management IP of the industrial switch, Ping the management IP of the industrial switch with the ping command. If you can ping, you can enter the web interface under normal circumstances.
If you can't get in, there may be the following reasons: first, the IP address conflicts, and the management IP of the industrial switch is duplicate with that of other devices. In this case, temporarily disconnect the industrial switch from other equipment, clean up ARP and re-enter. The possibility of IP conflict is eliminated. You can ping the management IP, but you can't enter the web management. At this time, please clean the browser cache and ARP. After cleaning the browser cache, close the browser, then open the browser and enter the management IP. 1.
