Armature Windings between DC insulation test specification

1 Scope

GB/T 22716-2008 is the Chinese national standard on test specifications of interturn insulation of armature winding for dc electrical machines, in the field of electrical engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 30 December 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 October 2009. Classification: ICS 29.160.30, CCS K23. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the test methods for insulating between DC Armature Windings and test limits. This standard applies to the rated voltage between 110V and above DC Armature Windings insulation withstand voltage test. Other DC Unless otherwise requested, should also refer to use. This standard does not apply to micro-motors.

2 Terms and definitions

The following terms and definitions apply to this standard.

2.1 Room with impulse voltage test DC Armature Windings insulation method. On the armature commutator span to take a while, in the end to the commutator segments impulse voltage is applied to the test.

2.2 Room with impulse voltage test DC Armature Windings insulation method. Armature commutator of two adjacent transducer impulse voltage is applied to the on-chip test.
