How to perform feed switch detection? What are the testing standards and items? Today, BAIJIAN will introduce the relevant content of feeder switch detection to everyone
The feed switch consists of two parts: an explosion-proof shell and a main body mainly composed of a circuit breaker.
. The body is equipped with a release, signal auxiliary device, and current transformer. The shell consists of three parts: the main chamber, the shell cover, and the junction box. The main chamber is divided into two types: circular and square. The connection between the main chamber and the shell cover mostly adopts a quick opening structure, and the circuit breaker cannot be closed after opening the cover
Testing items:
Insulation withstand voltage test, moisture resistance test, temperature rise test, shunt release action test, undervoltage release action test, short circuit protection test, overload delay protection test, determination of release setting range, leakage protection, leakage locking, explosion-proof performance
What is the testing cost?
The specific cost of feeder switch testing is determined based on factors such as testing items and laboratory qualifications. BAIJIAN will arrange engineers to confirm the relevant testing content with you before making a quotationWhere is the testing report done?
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:
