auto power converter 1, power sequence automatic conversion function 2, power protection function 3, monitoring function
A, overviewAlong with the rapid development of national economy, railway transportation, so more and more onerous to the security and reliability of railway power forward higher update request. The power supply quality problem in a prominent position, especially three-phase ac power sequence change directly affect the railway transportation safety. If cause rail rail control malfunction, interrupt normal traffic, the serious influence railway transportation and creates the mechanical power equipment damage, thorium in such situation,My company and shenyang railway JiWuChu power supply families and jinzhou railway luxurious combination of the three phase power facies sequences automatically converts device is developed, through repeated proof, test, has been developed successfully three-phase power facies sequences automatically converts. Three-phase power facies sequences automatically converts device consists of a sequence detection, phase lack detection, facies sequences automatically converts, fault alarm and remote monitoring of communication (oblique) composition.Takes microcontroller as control core, has reliable stability and high precision. This device after the port is put into operation, no matter how change, power grid facies sequences and the device output of three-phase ac power sequence always keeps consistent, use electric equipment in unmanned intervention under the condition of the normal work of the power supply, greatly reducing the maintenance and engineering construction of power supply when testing sequence workload, eliminate costly rigmarole of,
Meanwhile the device is phase lack power function, achieve the purpose of the protection of equipment. Power is at fault this device can automatically detect, fault is eliminated, the automatic delay recovery equipment power supply. Especially with the increase of railway railway, power supply raised taller requirement, this device can greatly improve the power systems, power supply reliability, avoid accidents, to ensure the safety of railway transportation.
