Foreword
This standard rule according to GB/T 1.1-2009 given draft.
This standard replaces GB/T 15290-1994 "electronic equipment technical condition with a power transformer and filter chokes."
This standard compared with GB/T 15290-1994, the following changes.
--- Reference standard in the "GB/T 2423.29" read "IEC 60068-2-21.1992";
--- "Type" to "category" (Chapter 3)
--- "Permissible operating temperature" to "maximum allowed operating temperature" (see 3.3);
--- "Strict class" to "severity level" (Chapter 4, and so many); Table 2 examples flag column "V-55/85.4" to
"V-55/85";
--- "Normal atmospheric conditions of the test" to "test normal atmospheric conditions" (see 4.3);
--- "Core" to "core" (the full text of 11);
--- Complements the leakage current of 5mA annotation (see 4.7.1 in Table 4);
--- "No strike appears empty, arcing" to "breakdown, arcing" (see 4.8.1);
--- "There are limited magnetic radiation" to "define a magnetic leakage" (see 4.13.1);
--- "There are limited noise requirements element noise level" to "the element defining the requirements of noise, the noise level" (see 4.14.1);
--- "Measured temperature is not higher than 30K" to "measured temperature is not greater than 30K" (see 4.18.1);
--- "Is not due droplets" to "not proper droplet or spike-like" (see 4.19.1);
--- "Element measured" to "measure element" (see 4.28.2d));
--- Table 12 C4 column "no-load voltage or the amount of empty feeling" with "no-load voltage or inductance" (see 5.3.3);
--- "E --- electric field strength, V/mm" changed to "E --- electric field strength in volts/meter (V/m)" (see 5.3.5);
--- "Power factor cosφ≤0.2 low power factor wattmeter" to "power factor cosφ≤0.2 power table" (Appendix A
NOTE);
--- Increased "when the product is used aluminum coil material selection, according to equation (B.5) calculates the temperature rise" (see B.8.2);
--- Legend relating to the accuracy of a few levels of expression were revised to use "%" means;
--- Related tables, formulas according to GB/T 1.1-2009 require modification, suspension and processed multiple segments.
