Dao cách ly điện cao áp DC dùng cho lọc bụi tĩnh điện GN-80/3-2S

1. Applicable scope of equipment:  
GN-80/3-2S high-voltage isolating switch is a left or right-hand wheel rotary DC high-voltage isolating switch. The switchgear is installed between the pressure-bearing insulator of the electrostatic precipitator and the high-voltage output of the silicon rectifier transformer. During the maintenance and repair of the electric field, it is used for the switching, transfer and grounding of the high-voltage power circuit of the electrostatic precipitator, so as to ensure the safety of the maintenance personnel. 2. Technical performance parameters: 1. Rated DC working current 2A ; 2. Rated DC working voltage 72KV . 3. Installation and use conditions: 1. The altitude does not exceed 2000 meters; 2. The ambient temperature is -20 ~ +60 ℃; 3. The relative humidity of the air does not exceed 95% (when the average temperature is 25 ℃); 4. The installation site should not be serious Conductive dust and corrosive metal iron filings that affect the insulation and conductivity of the isolating switch; 5. There is no obvious vibration at the installation location; 6. If the equipment needs to be installed outdoors, it should be installed in an iron box with a protective device. 4. Installation instructions: 1. The installation plane must be flat, and the bracket installation screw must be firm and reliable; 2
