STATION FOR TESTING ELECTRIC MACHINES Russian patent published in 2009 - IPC G01R31/34 

FIELD: electricity.

SUBSTANCE: present invention relates to electrical engineering, particularly to stations for testing electric supporting machines of a rolling stock. The station for testing electric machines has a control unit with measuring devices, a production base with elements for fastening at least, two electric machines, mainly dc current machines, a kinematic link for joining armatures of test electric machines, power supply unit, load resistor unit, switching unit, connected through control circuits and power cables. At the base there are fastening elements in form of threadolets, placed in accordance with connection sizes of standard series of electric supporting machines. The control unit with measuring devices is also connected to a computer and has measuring devices with sensors of temperature of windings and angular speed of drive shafts of the machines. The kinematic link of the machines is in form of a V-belt drive with a belt pulling device. The power supply unit has a device for blocking supply, which is linked to temperature and angular speed sensors. The power supply unit is independent and consists of a generator of different values and types of supply current and voltage and several detachable columns with the corresponding contact part of the test machines. The load resistor unit has a current and voltage stabiliser and an electric output with provision for connecting a working load.

EFFECT: more versatile device with the objective of carrying out safer and comprehensive tests of the whole standard series of electric supporting machines.
