运行中发生过当系统中某台变压器空载合闸时，正在运行的变压器零序过流保护误动跳闸事故。针对此事故的防范措施是：口正确计算各种系统运行方式下其它变压器空载合闸时在本变压器中性点流过的零序电流值，正确整定变压器零序电流保护的各段定值，GYG751CC2-T2G防止零序保护误动；口应尽量使设备在正常接线运行方式下运行，设法减少或避免在特殊运行方式-下运行，以防止零序保护定值可能不满足特殊运行方式的要求而造成零序保护误动作。针对和应涌流的产生原理，防止和应涌流的产生、防范措施是：口空载合闸前，将合闸变压器中性点不接地。使其合闸时只产生励磁涌流而不产生和应涌流。需要注意的是，如果将合闸变压器中性点不接地，应考虑变压器空载合闸时的过电压问题，GYG751CC2-T2G采取措施防止冲击过电压损坏变压器铁心或绝缘、口空载合闸前，将合闸变压器中性点接地，联系调度短时停运运行变压器中性点。富士伺服代理程先生需要请查看联系方式，静候咨询！近10年，特别是“九五”以来，我国DCS系统研发和生产发展很快，崛起了一批企业，如北京和利时公司、上海新华公司、浙大中控公司、浙江威盛公司、航天测控公司、电科院以及北京康拓集团等。这批企业研制生产的DCS系统，不仅品种数量大幅度增加，而且产品技术水平已经达到或接近***水平。在2001年应用的4426套DCS系统中，国产DCS系统为1486套，占35%。短短几年，GYG751CC2-T2G国外DCS系统在我国一统天下的局面从此不再出现。这些***化公司不仅占据了一定的市场份额，积累了发展的资本和技术，同时使得国外引进的DCS系统价格也大幅度下降，为我国自动化推广事业做出了贡献。与此同时，国产DCS系统的出口也在逐年增长。G6Q-SS1AGM6-B04MGM6-B06MGM6-B08MGM6-B12MG6F-AD2AG6F-DA2VG6F-DA2IG6F-HSCAG6F-POPAG6F-PP1DG6F-PP2DG6F-PP3DG6F-PP1OG6F-PP2OG6F-PP3OG6F-TC2AG6F-CUEBG6F-CUECG6L-FUEAG6L-RBEAGOL-***IAGOL-***QAGOL-***HAGM6-DMMAK4P-15ASGM4-PA1AGM4-PA2AGM4-B04MGM4-B06MGM4-B08MGM4-B12MGM4-B04EGM4-B06EGM4-B08EG4M-M032G4C-E041G4C-E121G4C-E301G4I-D22AG4I-D24AG4I-D22BG4I-D24BG4I-A12AG4I-A22AG4Q-RY2AG4Q-TR2AG4Q-TR4AG4Q-TR8AG4Q-TR2BG4Q-TR4BG4Q-SS2AG4Q-SS2BG4H-DR2AG4H-DT2AG4F-INTAG4F-AD2AG4F-AD3AG4F-DA1AG4F-DA3VG4F-DA2VG4F-DA3IG4F-DA2IG4F-TC2AG4F-RD2AG4F-AT3AG4F-PIDAG4F-HSCAG4F-PP1DG4F-PP2DG4F-PP3DG4F-PP1OG4F-PP2OG4F-PP3OG4F-POPAG4F-POPBG4L-CUEAG4L-FUEAG4L-RBEAGOL-***IAGOL-***QAGOL-***HAGM4-DMMAK7P-30SGM3-PA1AGM3-PA2AGM3-B04MGM3-B06MGM3-B08MGM3-B04EGM3-B06EGM3-B08EG3C-E061G3C-E121G3C-E301G3M-M064SG3I-D22AG3I-D24AG3I-D28AG3I-A12AG3I-A22AG3I-D22CG3I-A14AG3I-A24AG3Q-RY2AG3Q-SS2AG3Q-TR2AG3Q-RY4AG3Q-SS4AG3Q-TR4AG3Q-TR4BG3Q-TR8AG3Q-TR8BG3F-INTAG3F-AD3AG3F-AD4AG3F-AD4BG3F-DA3VG3F-DA3IG3F-DA4VG3F-DA4IG3F-PA1AG3F-PA2AG3F-AT4AG3F-PIDAG3F-HSCAG3F-POPAG3F-POAAG3F-T***AG3F-RD3AG3L-CUEAG3L-FUEAG3L-RBEAD-K59D-K59WD-G5BAD-Z73D-C73D-A73D-93AD-C73ED-C80D-F8PD-A96D-F8BD-F8N***CD-F9BVBXS1***CD-F9BVLBXS5***CD-H7BBXS4***CDL08-02BXS4***CD-***BBXS1***CD-***BBXS4***CD-***BLBXS10***CD-***NBXS4***CD-***NVBXS1***CD-***NVBXS5***CD-Y59ABXS2***CD-Y59ABXS4***CD-Y59ALBXS2***CD-Y59ALBXS4***CD-Y59BBXS3***CD-Y59BBXS15***CD-Y59BLBXS10***CD-Y59BLBXS5***CD-Z73BXS1***CD-Z73BXS6***CKCH06-M5BXS2***CKJH04-M5BXS10***CKJH06-01SBXS10***CKJL04-M5BXS10***CKJL06-01SBXS10***CKJS04-M5BXS10***CKJS06-01SBXS10***CKQ2E04-00BXS10***CKQ2E06-00BXS10***CKQ2E08-00BXS10***CKQ2E10-00BXS5***CKQ2E12-00BXS5***CKQ2H04-00BXS10***CKQ2H04-01SBXS10***CKQ2H04-02SBXS10***CKQ2H04-06BXS20***CKQ2H06-00BXS30***CKQ2H06-01SBXS9***CKQ2H06-01SBXS30***CKQ2H06-02SBXS30***CKQ2H06-03SBXS10***CKQ2H06-08BXS30***CKQ2H08-00BXS30***CKQ2H08-01SBXS30***CKQ2H08-02SBXS30***CKQ2H08-10BXS30***CKQ2H10-00BXS30***CKQ2H10-01SBXS10***CKQ2H10-03SBXS10***CKQ2H10-04SBXS30***CKQ2H10-12BXS10***CKQ2H12-03SBXS5***CKQ2H12-04SBXS5***CKQ2H12-16BXS5***CKQ2H16-00BXS5***CKQ2H16-04SBXS5***CKQ2L04-00BXS10***CKQ2L04-02SBXS10***CKQ2L04-M5BXS30***CKQ2L06-00BXS20***CKQ2L06-02SBXS20***CKQ2L06-03SBXS10***CKQ2L06-M5BXS10***CKQ2L08-00BXS20***CKQ2L08-01SBXS10***CKQ2L08-02SBXS20***CKQ2L08-03SBXS10***CKQ2L10-00BXS20***CKQ2L10-01SBXS10***CKQ2L10-02SBXS10***CKQ2L10-03SBXS10***CKQ2L10-04SBXS10***CKQ2L12-00BXS5***CKQ2L12-02SBXS5***CKQ2L12-03SBXS5***CKQ2L12-04SBXS5***CKQ2L16-00BXS5***CKQ2L16-03SBXS5***CKQ2L16-04SBXS5***CKQ2LE06-00BXS10***CKQ2LE08-00BXS10***CKQ2LE10-00BXS10***CKQ2P-04BXS10***CKQ2P-06BXS10***CKQ2P-08BXS10***CKQ2P-10BXS10***CKQ2S04-01SBXS10***CKQ2S04-M5BXS10***CKQ2S06-01SBXS10***CKQ2S06-02SBXS10***CKQ2S06-M5BXS10***CKQ2S08-01SBXS10***CKQ2S08-02SBXS10***CKQ2S10-02SBXS5***CKQ2S10-03SBXS5***CKQ2S12-02SBXS5***CKQ2S12-03SBXS5***CKQ2T04-06BXS10***CKQ2T04-M5BXS10***CKQ2T06-00BXS10***CKQ2T06-01SBXS10***CKQ2T06-08BXS10***CKQ2T06-M5BXS10***CKQ2T08-00BXS10***CKQ2T08-01SBXS10***CKQ2T08-02SBXS10***CKQ2T08-10BXS10***CKQ2T10-00BXS5***CKQ2T10-02SBXS5***CKQ2T10-12BXS5***CKQ2T12-00BXS5***CKQ2T12-03SBXS5***CKQ2T12-04SBXS5***CKQ2T16-00BXS5***CKQ2U04-06BXS10***CKQ2U06-00BXS10***CKQ2U06-08BXS10***CKQ2U08-00BXS10***CKQ2U08-10BXS10***CKQ2U10-00BXS5***CKQ2U10-12BXS5***CKQ2U12-00BXS10***CKQ2V04-M5BXS10***CKQ2V06-01SBXS10***CKQ2V06-M5BXS10***CKQ2V08-02SBXS10,GYG751CC2-T2G***CMHZ2-10DBXS10***CMXS6-10BXS1***CMXS6-20ABXS1***CMXS8-20ABXS3***CMXS8-20ABXS3***CMXS8-30ABXS3***CMXS8-30ASBXS3***CMXS8-30ASBXS1***CMXS8-40BXS1***CMXS8-40ABXS1***CMXS8-50ABXS1BANNERPFC-2BXS4***CSYJA712-01-FBXS1CDQ2A16-25DM5个AW20-025个AW20-02C3个RBC141114个RB14113个SY5220-5LZD-C626个SY5120-5LZD-C615个ISE40-01-22L15个AS1201F-M5-06100个AS2201F-01-06S100个CDJ2B6-15SR-B15个CUJB10-10D10个G36-10-0113个CDJ2KB16-15-B2个VF3130-5GB-022个***4000-04-5DZB8个D-A93L60条SS5Y5-20-048个)
