1、 Purpose
Jzy1-k fast DC relay is suitable for DC operation of various protection automatic control lines, as an outlet relay to increase the number capacity of protection control circuit contacts.
The contact breaking time of common DC operated relay is more than 30ms. Jzy1-k fast DC relay can meet the requirements of DC operation quick breaking less than 20ms, can meet the requirements of high-voltage switch anti tripping protection line after high-voltage switch factory test.
4、 Conditions of use
1. The altitude shall exceed 2000m;
2. The ambient air temperature is + 40 ℃ ~ - 25 ℃;
3. The inclination angle between the installation surface the vertical plane shall exceed + 22.5 ° (see Figure). When the site vibration is large, it is recommended to install in the direct vibration direction to prevent vibration absorption;
4. It is installed in the environment that can prevent rain, wind sand.
