6.2.2.2. Generator check at the stand

The scheme of connections of the generator at the stand for check

1 – the voltmeter;
2 – the switch;
3 – the ampermeter;
4 – the storage battery;
5 – a rheostat;
6 – the generator

Check at the stand allows to define serviceability of the generator and conformity of its characteristics to the nominal. At the checked generator of a brush rings the pure should be ground well in to contact rings of a collector, and.

PERFORMANCE ORDER
1. Establish the generator on the stand and execute connections as is shown in fig. the Scheme of connections of the generator at the stand for check.
2. Include the stand electric motor, a rheostat 5 establish pressure on an exit of the generator 14 In and finish frequency of rotation of a rotor to 5000 mines-1. Allow to the generator to work on this mode not less than 2 mines, and then measure a return current strength. At the serviceable generator it should be not less than 44 And.
3. If the measured size of a given current is much less, it speaks about malfunctions in windings статора and a rotor, about damage of gates or deterioration of contact rings and brushes. In this case careful check of windings and gates is necessary to define a malfunction place.
4. At suspicion on malfunction of gates выпрямительного the generator block, check up a return current strength on the heated-up generator. Such check allows to reveal better malfunction of gates on sharp decrease in a current of return at generator rise in temperature.
5. For warming up allow to the generator to work not less than 15 mines at frequency of rotation of a rotor of 5000 mines-1 and pressure 14 In on a generator exit. Then measure a return current strength. On the heated-up generator it should be not less than 42 And.
