Normal working conditions:
1. The de-excitation switch is suitable for the following working conditions:
(1) The altitude does not exceed 1000 meters;
(2) The temperature of the surrounding medium is not higher than +40 °C and not lower than -80 °C;
(3) Air The relative humidity is not more than 85%;
(4) The amplitude of the installation is not more than 0.5 mm, the frequency is not more than 600 times per minute;
(5) The inclination from the vertical plane is not more than 5 degrees;
(6) In the medium without explosion hazard , the medium does not enough to corrode metal and damage the insulation gas or conductive dust place;
(7) filled with a water-resistant device or without steam environment;
2, excitation switch it into the following types according to different ways;
( 1) Current level; 400 and 630 amps;
(2) Outlet mode; board forward line;
(3) Operation mode; direct handle operation and electromagnet operation;
(4) Device mode;
