More Information
Summary:The invention provides a low-voltage power system control apparatus. The low-voltage power system control apparatus comprises a medium voltage switch cabinet, a first transformer, a second transformer, a normal low voltage switch cabinet, an emergency low voltage switch cabinet and an emergency generator, and also comprises a synchronizing device, a PLC apparatus and four selector switches; and the PLC apparatus directly controls a switch-on and switch-off loop of each switch to realize safe and sequential operation of each switch of the low-voltage power system in all working conditions. The low-voltage power system control apparatus is simple in structure, simple and convenient to install, simplifies secondary wiring of an offshore oil platform power system, effectively shortens debugging time and eliminates possibility of electrical misoperation, improves operational reliability and safety of the system, and effectively lowers primary investment and maintenance cost. 本发明提供种低压电力系统控制装置，包括中压开关柜、第变压器、第二变压器、正常低
