3BSE018157R6控制模塊,PM861AK01使用區(qū)域
高低電壓保護(hù)：市電電壓過高或過低時(shí)，UPS內(nèi)穩(wěn)壓器(AVR)將做適當(dāng)?shù)恼{(diào)整，使市電的電壓保持在可使用范圍內(nèi)。■ 波形失真處理：由于電力經(jīng)由輸配電線路傳送至客戶端，各種機(jī)器設(shè)備的使用往往造成市電電壓波形失真，UPS一般設(shè)計(jì)失真率<3%?！?頻率穩(wěn)定：
3BSE018157R6控制模塊,PM861AK01使用區(qū)域發(fā)電機(jī)運(yùn)轉(zhuǎn)時(shí)，受到客戶端用電量的突然變化造成轉(zhuǎn)速的變動(dòng)將使轉(zhuǎn)換出來的電力頻率飄移不定，UPS轉(zhuǎn)換的電力可提供穩(wěn)定的頻率。■ 電壓穩(wěn)定：
市電電壓易受電力輸送線路品質(zhì)的影響，使用在線式UPS電源可提供穩(wěn)定的電壓電源，電壓變動(dòng)不到2V，可延長設(shè)備壽命及保護(hù)設(shè)備。
■ 突波保護(hù)：
UPS一般會(huì)加裝突波吸收器或尖端放電設(shè)計(jì)吸收突波，以保護(hù)用戶設(shè)備。
■ 監(jiān)控電源：
配合UPS電源的智能型通訊接口及監(jiān)控軟件可記錄市電電壓頻率、停電時(shí)間及次數(shù)來，通過設(shè)定UPS電源定時(shí)開關(guān)機(jī)時(shí)間表來節(jié)約能源。為保證電源設(shè)備穩(wěn)定工作不被干擾，需要在電源設(shè)備的輸入端并聯(lián)電容。同時(shí)為實(shí)現(xiàn)電源設(shè)備的輸入過載保護(hù)，還會(huì)在電源設(shè)備的輸入端串聯(lián)保險(xiǎn)絲或斷路器等。由于輸入電容的存在，電源設(shè)備在啟動(dòng)過程中將會(huì)產(chǎn)生較大的輸入沖擊電流，可能會(huì)導(dǎo)致保險(xiǎn)絲熔斷或斷路器跳閘等問題。供電系統(tǒng)啟動(dòng)時(shí)，輸入電壓Vin快速升高，輸入電壓Vin通過輸入等效阻抗Rin對輸入等效大電容Cin進(jìn)行充電。輸入回路沒有使用輸入沖擊電路抑制電路時(shí)，由于輸入等效阻抗Rin主要為PCB走線阻抗、EMC電路中共模/差模電感阻抗和端口連接阻抗等，輸入等效阻抗Rin相對較?。ㄏ鄬τ谳斎霙_擊電路抑制電路的阻抗可忽略不計(jì)），將導(dǎo)致較大的輸入沖擊電流。
在110VDC輸入，輸入等效大電容Cin為100uF，未加電流抑制電路時(shí)，輸入沖擊電流典型波形如圖2所示，輸入沖擊電流達(dá)到170A。
輸入沖擊電流過大將會(huì)導(dǎo)致輸入端保險(xiǎn)絲熔斷或斷路器跳閘等問題，對于高可靠性要求的行業(yè)應(yīng)用，進(jìn)行輸入沖擊電流抑制必不可少。電阻器串聯(lián)在電源設(shè)備的輸入回路中，進(jìn)行輸入沖擊電流抑制，輸入回路串聯(lián)電阻器供電系統(tǒng)開始供電時(shí)，輸入等效大電容Cin電壓較小，輸入沖擊電流最大為，為有效抑制輸入沖擊電流
equipment, and then it also needs 2 months to program. In addition, the on-site installation and debugging time is as long as 20 ~ 30 days. During the peak period of market demand for all steel radial truck tire, users hope that the company can
Deliver the tire forming equipment as soon as possible. Therefore, Qingdao University soft control company needs to find a faster way to integrate the motion control system into the equipment, so that the products can be put on the market faster and meet the urgent needs of users. Integrated control after comparing various solutions, Qingdao University soft control company adopted Rockwell Automation's integrated architecture control system solution, and gradually achieved success in a variety of application projects. Now, they have introduced this integrated control solution into the tire forming equipment to meet the demanding requirements of users with its high-precision positioning performance. The full range of motion control integrated solutions adopted by them include Allen Bradley ControlLogix controller, Allen Bradley kinetix 6000 multi axis servo driver and Allen Bradley
