Dao cách ly điện cao áp DC dùng cho lọc bụi tĩnh điện GN-90/3-1S

1. Applicable scope of equipment:  
GN-90/3-1S high voltage isolating switch is a left or right hand wheel rotary DC high voltage isolating switch. The switch device is installed between the pressure 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 90KV . 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
