GB/ t1032-2012 three-phase asynchronous motor test method.

2018-03-02  admin 阅读 149

GB/T 1032-2012 "three-phase asynchronous motor test method" sets out the test requirements and test methods for three-phase asynchronous motors, which is suitable for three-phase asynchronous motors.

GB/T 1032-2012 is drafted according to the rules given in GB/T 1.1-2009.

This standard replaces GB/T 1032-2005 "three-phase asynchronous motor test method". Compared with GB/T 1032-2005, the main technical changes are as follows:

(see, table 1), which increases the measurement method of absorption ratio and polarization index;

- increases the determination of other insulation resistance;

- increased other thermal test method, GB/T 21211-2007 specified in other applicable methods, such as induction motor superposition method (see six of GB/T 21211-2007), equivalent load method of induction motor (see 10 of GB/T 21211-2007);

- the load stray loss of induction motor (see 10.6.6) was determined by the test method (eh-star method).

- increased test method and efficiency measurement uncertainty (see 11.1.2);

- increased bearing current measurement (see 12.12);

-- the total content of the load stray loss Ps value is determined according to the rated input power of the motor (see 2005).

-- version;

-- delete the total value of the stray losses of the load when the load is rated at (see in 2005);

- appendix D is deleted (see 2005 version);

This standard refers to the test method for determining the loss and efficiency of the rotary motor (except traction motor) using IEC 60034-2-1:2007.
