DEVICE FOR UNINTERRUPTED ENERGY SUPPORT OF EQUIPMENT OF PUT-MEASURING LABORATORY ON THE BASIS OF AC ELECTRIC CARRIER

摘要

The device allows to increase reliability due to uninterrupted power supply of equipment. The specified technical result is achieved by the fact that the device is a traction transformer (TT) with auxiliary winding (OSN), a set of AC consumers (MB), a battery charge unit (BZB), a battery (AB), a power switching unit (BKP), a set DC consumers (MK). MB is connected to the first output of the OCH. The second output of the OCH is connected to the first input of the BKP, the output of which is connected to the input of the MC. The third output of the OCH is connected in series through the first input of the BZB and the battery to the second input of the BKP. An energy supply unit (BEO), an energy supply control unit (BUE), an auxiliary diesel generator set (DGU), and equipment for a diagnostic laboratory (ODL) were introduced. The first input of the BEO is connected to the fourth output of the OCH, and its second input is connected to the output of the battery. The first power output of the BEO is connected to the input of the ODL. The second, third and fourth control input of the BEU respectively connected to the first, second and third control input of the BUE. The first control output of the BUE is connected to the fourth control input of the BEO, and its second control output is connected to the control input of the diesel generator set. The first output of the diesel generator set is connected to the third input of the BEO, and its second output is connected to the second input of the BZP. BEO is made with the possibility of converting direct voltage to alternating voltage, as well as connecting DGU to transmit an alternating three-phase voltage through its first power output to the input of the ODL. 1 s.p. f-ly, 3 Fig.
