summary:
The JN22B-40.5 indoor high-voltage grounding switch (hereinafter referred to as the grounding switch) is a new product developed by the company. Its performance complies with the national standard GB1985-2004 "AC High Voltage Isolating Switches and Grounding Switches", and is suitable for power systems with three-phase rated voltage of 40.5kV and AC 50Hz. It can be used in conjunction with KYN61-40.5 high-voltage switchgear and other models of high-voltage switchgear as grounding protection during high-voltage equipment maintenance. The JYN22B-40.5/31.5 indoor high-voltage grounding switch is an improvement on the above grounding switch, with a simple and compact structure, consistent performance, and easy to operate at small angles. It is the same as the JN15-12 indoor high-voltage grounding switch and can use the connecting and transmission components of the JN15-12 indoor high-voltage grounding switch.
Normal usage conditions:
◇ Altitude not exceeding 1000m;
Surrounding air temperature: upper limit+40 ℃, lower limit -25 ℃;
The seismic intensity shall not exceed 8 degrees;
◇ Installed in places without fire, explosion hazards, severe dust, chemical corrosion, and severe vibration.
