Product Details:

GN-72 DC disconnector, electric dust removal single pole high voltage isolation switch GN3-72/2-1S 72KV 2A

 

General Introduction

The GN-72/3-1S high-voltage isolating switch is a left or right handwheel rotary DC high-voltage isolating switch. The switchgear is installed between the pressure-insulated insulator of the electrostatic precipitator and the high-voltage output of the silicon rectifier transformer. When the electric field of the precipitator is maintained and overhauled, Switching, transferring and grounding the high-voltage power circuit of the electrostatic precipitator to ensure the safety of maintenance personnel.

 

Technical Specification

1, rated DC operating current 2A;

2, rated DC operating voltage 72KV.

 

Installation and Use Conditions: 

1, the altitude does not exceed 2000 meters;

2, the ambient temperature is -20 ~ +60 ° C;

3, the relative humidity of the air does not exceed 95% (average temperature 25 ° C);

4, the installation site should be no serious Conductive dust and corrosion metal iron which affect the insulation and conductivity of the isolating switch;

5. No obvious vibration at the installation position;

6. If the equipment is to be installed outdoors, it should be installed in the iron box with protection device.

 

Installation Instructions:

1, the installation plane must be flat, the bracket installation screw must be firm and reliable;

2, the isolation switch high-voltage power supply terminal from other objects around the space should ensure greater than 300mm clearance;

3, when the switch handle is abnormal, should be timely Check the maintenance to avoid damage to other parts.

4. The isolation switch should be arranged and maintained by the maintenance personnel. The bearings should be removed and greased every two years.
