R-S108V01-16-24VDC-C10-1模塊,PHOENIX參數(shù)說明
對裝置的可靠性、可維修性和預(yù)估的使用壽命；如可維修性驗(yàn)證：采用指示燈進(jìn)行指示，定位故障發(fā)生點(diǎn)，方便進(jìn)行維修；如可靠性運(yùn)行驗(yàn)證，運(yùn)行里程不少于10W公里，運(yùn)行時(shí)間不少于1年等要求；其他要求：如對于供電中斷、跌落等要求，一般模塊電源設(shè)計(jì)難滿足10mS中斷需求，尤其是對于低壓輸入產(chǎn)品，需要增加外圍輸入輸出電容滿足客戶需求；如對于蓄電池的短路保護(hù)措施，一般采用防反二極管或者機(jī)械設(shè)計(jì)來規(guī)避此方面的失效。
R-S108V01-16-24VDC-C10-1模塊,PHOENIX參數(shù)說明車載電子設(shè)備的電源選型
隔離電源作為防止故障擴(kuò)散的方法之一，在車載電子設(shè)備中起著重要的作用；但是車載在運(yùn)行過程中，存在著各種狀態(tài)，如劇烈的振動(dòng)狀態(tài)；劇烈的外界環(huán)境溫度變化率等情況出現(xiàn)；普通常規(guī)的工業(yè)級電源很難滿足其使用要求；那么車載電路電源需要要求呢？
1.沖擊和振動(dòng)：
由于鐵路運(yùn)行環(huán)境的性質(zhì)，鐵道車輛會(huì)受到?jīng)_擊和振動(dòng)。對于安裝在鐵道車輛上的電子設(shè)備必須進(jìn)行隨機(jī)振動(dòng)和沖擊試驗(yàn)要求。對于電源模塊來說，采用灌膠固定PCB板載元器件的方法，可有效增強(qiáng)其抗振動(dòng)和沖擊的能力。
如金升陽鐵路電源R3系列產(chǎn)品可完全滿足振動(dòng)10~55Hz 10g 30Min along X Y Z要求。
車載蓄電池的額定供電電壓主要有以下幾種：24V、48V、72V、96V、110V等5種規(guī)格；由于輔助設(shè)備啟動(dòng)或者感性負(fù)載進(jìn)行切換，會(huì)產(chǎn)生浪涌電壓或者低電壓出現(xiàn)；電源設(shè)計(jì)的輸入電壓參數(shù)能夠在0.6VN和1.4VN電壓范圍內(nèi)正常工作；并且電源廠家都會(huì)兼容多個(gè)車載蓄電池電壓等級。
如1.金升陽鐵路電源產(chǎn)品URB1D24YMD-6WR3，輸入電壓范圍為40VDC~160VDC，可兼容車載蓄電池72VDC、96VDC、110VDC三個(gè)供電電壓等級。電源系統(tǒng)：電源系統(tǒng)主要負(fù)責(zé)完成設(shè)備內(nèi)部所有部件的供電，通常由常規(guī)的開關(guān)電源和電池組成。
the running of the car barrier can also be stopped when the timing time is up), and set the station number of the substation PLC.
Determination of the position of the main station tramcar position detection sensor
A slide block that does not rotate with the lead screw is fixed on the rotating lead screw of the depth indicator, the winch rotates forward, the mine car descends, and the slide block on the rotating lead screw slides downward.
1) When the tramcar just runs below the car barrier, stop the winch at this time, and the position of the slider on the lead screw of the depth indicator represents the actual position of the tramcar. An inductive proximity sensor is fixed at the end face of the slider, and the sensing surface of the sensor is aligned with the center of the end face of the slider, so that the sensor can sense the output signal of the slider.
2) The position detection of each set of car barriers is the same. How many inductive proximity sensors should be fixed on the depth indicator of the car barriers in the roadway to determine the position of the mine car.
