UNIVERSAL METER for traction substations and electric rolling SUBWAY

摘要

The utility model relates to a power supply for subways, and can be used to measure voltages, currents and other electrical high voltage equipment magnitudes traction substations and electric rolling stock.; The technical problem - the possibility of providing long-term high-precision measurement of electrical quantities in high voltage circuits AC and DC traction substations and electric rolling subways.; Universal meter includes a high-voltage measuring unit consisting of a microcontroller, associated with the current measurement channels, voltage common measurement unit real-time clock, an acceleration sensor for two coordinate axes, the power manager, combined with the watchdog timer, the interface unit with a serial communication channel, and isolation unit, consisting of a power unit and the optical communications channels, one of which is connected to transmit information to a recording device, a microcontroller coupled to the recording they device via optical channel interchange unit or directly through the interface unit with a serial communication channel. 1 Fig.
