in this issue of the article to give you to sort out the contactor detection items and standards and some procedures for you to read, for details, please see below:
Contactor, it is in the coil through the current to produce magnetic field, and make the contact closed, so as to control the load of equipment, contactor is divided into ac contactor (voltage AC) and DC contactor (voltage DC), it is applied to power, distribution and electricity, if we refer to the industrial electricity using the coil through the current to produce magnetic field, contact closed, to control the load of electrical appliances, so it can be said that the contactor is composed of electromagnetic system and contact system.
1. Detection items of the contactors:
Electromagnetic strength, coil detection, resistance value, high temperature resistance test, low temperature resistance test, magnetization strength, reliability test, aging test, weather resistance test, service life detection, etc.
2. Test criteria for partial detection of contactors:
GB / T 8871-2001 AC contactor energy-saving appliance;
GB / T 14808-2016 High-voltage AC contactor, contactor-based controller and motor starter;
GB / T 17885-2016 Electromechanical contactors for household and similar purposes;
GB 21518-2008 AC contactor energy efficiency limit value and energy efficiency grade;
GB / Z 22200-2016 Small Capacity AC Contactor reliability test;
