Safety and reliability are the first and most critical elements to measure the China Charging pile DC contactor, which are mainly reflected in arc extinguishing ability and insulation voltage. In addition to safety and reliability of Charging pile DC contactor, the environmental adaptability should also be considered in the design.
The China Charging pile DC contactor is different from general industrial contactor products. The conditions of the use environment have more stringent requirements on its adaptability. The Charging pile DC contactor must meet the basic conditions such as wide temperature range, high protection level and high vibration resistance at the same time. .
1. High and low temperature design: The China Charging pile DC contactor needs to meet the temperature requirements for normal use of electric vehicles and charging piles (machines) in extreme weather. Including the ambient temperature of Charging pile DC contactor storage, the ambient temperature of normal operation and the ambient temperature requirements under extreme conditions.
2. Protection grade design: The China Charging pile DC contactor needs to meet the normal operation under harsh environmental conditions, and the product can be used normally in rain and dust environments. The Charging pile DC contactor should completely prevent dust from entering, meet the requirements of short-term water immersion, and have a high protection level.
3. Anti-vibration performance design: The China Charging pile DC contactor product needs to have strong vibration resistance and shock resistance.
