How to inspect high-voltage AC circuit breaker equipment? What are the testing standards and items? Today, BAIJIAN will introduce to you the relevant content of high-voltage AC circuit breaker equipment testing
Testing scope:
High voltage AC vacuum circuit breakers, high voltage AC sulfur hexafluoride circuit breakers, high voltage AC circuit breakers, etc.
Testing items:
Insulation test, radio interference voltage (r.i.v.) test, measurement of main circuit resistance, temperature rise test, short time withstand current and peak withstand current test, inspection of protection level, sealing test, electromagnetic compatibility (EMC) test, additional tests for auxiliary and control circuits The X-ray test program, mechanical and environmental tests, and various regulations for making and breaking tests of vacuum arc extinguishing chambers, as well as the asymmetric criteria given in the requirements What is the testing cost for short-circuit making and breaking tests, including the test circuit, short-circuit test parameters, short-circuit test procedures, basic short-circuit test methods, critical current tests, single-phase and out of phase ground fault tests, near zone fault tests, out of step making and breaking tests, capacitive current making and breaking tests
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
