ATNSX型双电源切换开关自动切换故障原因探讨

Discussion on Automatic Switching Failure of ATNSX Dual Power Switch

双电源切换开关(ATSE)广泛应用于电网、变电站、工矿企业。区别于BZT装置应用于6~35 kV高压系统,ATS一般用于低压380 V双电源回路。配电箱的进线为双电源时,只要检测到主回路电源消失,自动切换,投入备用电源。鳌头分布式能源站现场低压设备多采用施耐德万高生产ATNSX A型双电源切换开关,主要探讨施耐德万高ATNSX A型双电源切换开关现场使用中出现的故障,分析了可能引起故障的原因。

Automatic Transfer Switching Equipment(ATSE)is widely used in power grid,substation,industrial and mining enterprises.Unlike the BZT device applied to the 6~35 kV high voltage system,the ATS is generally used for the low voltage 380 V dual power circuits.When the incoming line of the distribution box is double power supply,as long as the main circuit power supply disappears,it can automatically switch the standby power supply.The on-site low-voltage equipment of Aotou distributed energy station mostly adopts Schneider Wangao ATNSX A dual power switch.The faults of Schneider Wangao ATNSX A dual power transfer switch in field use are discussed,and the possible causes of the faultsare analyzed.
