Foreword
This instructional document has been drafted in accordance with the rules given in GB/T 1.1-2009.
This Guidance Document replaces GB /Z 22074-2008 "Plastic case circuit breaker reliability test method". versus
GB /Z 22074-2008 compared to the main technical changes are as follows.
--- Normative references, update reference standard version number, delete the corresponding IEC number, increase the reference file content;
--- Change the instantaneous instantaneous protection success rate and instantaneous instantaneous reliability test to short circuit protection success rate and short circuit reliability test.
--- Unified short-circuit protection success rate rating and overload protection succession level name, change the success rate rating value;
--- Modify the test conditions (see 5.1.1);
--- Complement the requirements of the test power (see 5.1.3);
--- Increasing the test test after the test content of the test (see 5.3.1.3);
--- Added to the circuit breaker with electronic overcurrent release and circuit breakers with electromagnetic overcurrent release reliable protection
Description of the corresponding method of sexual testing (see 5.3.2.2);
--- Removed "momentary protection reliability test should be conducted before and after the operation reliability test 50% nf times.";
--- Increased the description of the electronic tripping device during the overload protection reliability test (see 5.3.3.2);
--- Removed "Overload protection reliability test should be conducted before and after the operation reliability test 50% nf times. Overload protection reliability test
After the instantaneous protection reliability test. ";
--- Increasing the speed of operation of electric and pneumatic operation of the test device requirements (see 5.5);
--- Modify the success rate of short-circuit protection and overload protection success rate of the test sample source requirements and exit mechanism;
--- Added Appendix C "on the plastic shell circuit breaker with electrical load reliability test methods and to determine the reliability of the number
According to the steps ";
--- Added Appendix D "electromagnetic environment on the reliability of plastic shell circuit breakers."
