操作員界面的通訊接口有如下幾種:
◆EtherNet/IP(以太網(wǎng))通訊,連接PLC-5E、SLC 5/05、ENI模塊、通過1756以太網(wǎng)網(wǎng)橋的Logix 5000控制器。
◆ControlNet(設(shè)備網(wǎng))通訊,與ControlNet網(wǎng)絡(luò)上的控制器進(jìn)行通訊,支持預(yù)定的和非預(yù)定的PLC-5和ControlLogix消息、支持冗余電纜。
◆DeviceNet(設(shè)備網(wǎng))通訊,在設(shè)備網(wǎng)上進(jìn)行設(shè)備級的通訊。
◆Data Highway Plus(DH+)通訊,在Allen-Bradley DH+網(wǎng)絡(luò)上連接到一個(gè)或多個(gè)PLC、SLC 5/04、ControlLogix控制器。
◆遠(yuǎn)程輸入輸出(Remote I/O)通訊,連接到一個(gè)PLC、SLC或ControlLogix 系統(tǒng),同時(shí)支持離散量數(shù)據(jù)傳輸和塊數(shù)據(jù)傳輸方式。
◆DH-485通訊,在DH-485網(wǎng)絡(luò)上連接到一個(gè)或多個(gè)SLC或MicroLogix控制器。
◆RS-232(DH-485協(xié)議)通訊,作為一個(gè)專線連接用于傳輸高優(yōu)先級數(shù)據(jù),以點(diǎn)對點(diǎn)方式連接MicroLogix或SLC控制器。
◆RS-232(DF1協(xié)議)通訊,在一個(gè)點(diǎn)到點(diǎn)DF1通訊鏈路上連接到單個(gè)SLC,PLC-5、或MicroLogix控制器。
◆Profibus通訊,使用Profibus DP標(biāo)準(zhǔn)協(xié)議以與西門子或其他控制器進(jìn)行高速數(shù)據(jù)傳輸。
◆MODBUS通訊,使用半雙工,主從協(xié)議在諸如Modicon和GE等非Rockwell自動化控制結(jié)構(gòu)中進(jìn)行通訊。
4.峰值耐受電流反映了斷路器承受由于短路電流產(chǎn)生電動力的耐受性能,它決定斷路器的導(dǎo)電部分和絕緣支撐件的機(jī)械強(qiáng)度以及觸頭的結(jié)構(gòu)形式。
5.操作性能
(1)全開斷時(shí)間 是指斷路器接到分閘命令瞬間起到電弧熄滅為止的時(shí)間間隔。即
(4-10-4)
式中 ——全開斷時(shí)間,s;
——分閘時(shí)間,s;從斷路器接到分閘命令瞬間到
所有相的觸頭都分離的時(shí)間間隔,亦稱為斷
路器固有分閘時(shí)間;
——燃弧時(shí)間,s;是指某一相首先起弧瞬間到所
有相電弧全部熄滅的時(shí)間間隔。
全開斷時(shí)間是說明斷
路器開斷過程快慢的主
要參數(shù),它直接影響故
障對設(shè)備的損壞程度、
故障范圍、傳輸容量和
系統(tǒng)的穩(wěn)定性。 斷路器開斷時(shí)間示意圖
(2)合閘時(shí)間 處于分閘位置的斷路器,從接
到合閘命令瞬間起到所有相的觸頭均接觸為止的
時(shí)間稱為合閘時(shí)間。
6.自動重合閘性能
自動重合閘的操作循環(huán):分— —合分— —合分。 為斷路器開斷故障電路,從電弧熄滅起到電路重新接通的時(shí)間,稱為無電流間隔時(shí)間,一般為0.3s或0.5s; 為強(qiáng)送電時(shí)間,一般為180s。
斷路器開斷時(shí)間與無電流間隔時(shí)間之和稱為自動重合閘時(shí)間。
金屬短接時(shí)間系指斷路器重合閘操作后,觸頭閉合到第二次觸頭分開所需用的時(shí)間。
