Energy efficiency testing of AC contactorsHow to apply for a report? What items need to be tested? We will conduct testing and evaluation in strict accordance with the standards. We can also provide personalized testing plans and reports according to your needs.
Contactor is a device that generates a magnetic field through the current flowing through the coil, causing the contact to close and thus controlling the load. Contactors are divided into AC contactors (voltage AC) and DC contactors (voltage DC), which are applied to power, distribution, and electric field integration. If we broadly speaking, it refers to industrial electricity that uses the current flowing through the coil to generate a magnetic field, causing the contact to close, To achieve load control of electrical appliances, it can be said that contactors are composed of electromagnetic systems and contact systems p>
1. Testing items for contactors:
Electromagnetic strength, coil testing, resistance value, high temperature resistance test, low temperature resistance test, magnetization strength, reliability test, aging test, weather resistance test, service life test, etc p>
Secondly, testing standards for contactors:
GB/T 8871-2001 AC contactor energy-saving devices p> GB/T 14808-2016 High voltage AC contactors, contactor-based controllers, and motor starters p> GB/T 17885-2016 Electromechanical contactors for household and similar purposes p> GB 21518-2008 Energy Efficiency Limits and Energy Efficiency Grades for AC Contactors p> GB/Z 22200-2016 Reliability Test for Small Capacity AC Contactors p> GB/Z 22201-2016 Reliability Test for Contactor Relay p> GB/T24975.4-2010 Guidelines for Environmental Design of Low Voltage Electrical Appliances - Part 4: Contactors p> GB/T 30215-2013 General Requirements for Aircraft Electromagnetic Relays and Contactors p> AS 60470-2001 High voltage AC current contactors and engine elicitors based on current contactors p> AS/NZS3947.4.3-2000 Low voltage switchgear and controllers - Part 4.3: Contactors and motor starters p>
III. Contactor detection process:
1. Consult the communication department staff and submit the detection requirements.
p> 2. Send samples to our laboratory. (Determine the experimental plan and provide a quotation based on the type of experiment and customer needs)3. Both parties shall determine p> 4. Sign a confidentiality agreement to strictly protect customer privacy p> 5. Arrange the experiment and begin the experiment p> 6. Complete the experiment, organize the data, and issue a testing report p> 7. Mail the report P>
