A circuit breaker refers to a switching device that can switch, carry, and break the current in normal circuit conditions, and can break the current in abnormal circuits within a specified time. It can also be used to distribute electrical energy, infrequently start asynchronous motors, protect power lines and motors, and automatically cut off the circuit in case of severe overload, short circuit, undervoltage, and other faults, Its function is equivalent to a combination of fuse switches and over/under heat relays. They are generally composed of contact systems, arc extinguishing systems, operating mechanisms, releases, shells, etc
Testing items for circuit breakers:
Vacuum degree, performance testing, high and low temperature resistance, combustion performance, contact pressure, mechanical characteristics, aging test, dielectric test, corrosion test, explosion-proof test, flammability test, service life, etc
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:
