GN2-40.5 high voltage isolation switch [indoor]

I. Overview

Within GN2-10 indoor high voltage isolation switch is a three-phase AC 50HZ high voltage switchgear for rated voltage of 10 to 35KV power system is, as the opening and closing circuits.

Use of environmental conditions:

Altitude: not exceed 3000m;

Ambient temperature: not higher than + 40 ℃, not lower than -30 ℃; daily temperature is 15 ℃;

Indoor air relative humidity: no more than 90% (at + 25 ℃ when);

Earthquake intensity: not more than 8 degrees;

Installation site should not seriously affect the isolation switch insulation and conductivity of gas, steam, chemical deposition, salt spray, dust, dirt and other explosive, corrosive substances;

Installation site should be no frequent violent vibration.

 

II. Technical Parameters

       III. Structure description

The series isolation switch is a three-pole-type linkage, which insulator by the undercarriage, the pillar, rod insulators, conductive knife, static contact and magnetic lock plate and other components. Brace made of welded steel, running through the shaft portion, the shaft is welded and connected to the lever arm connected to the insulator, the shaft can be installed at both ends of the handle and actuator connected to dividing closing. Post insulator mounted on the chassis to support the conductive portion and the insulation purposes. Knife equipped with a magnetic lock on the board. The role of the magnetic lock plate at the time of the short-circuit current through strengthening the attractiveness of the same polarity between the conductive sheet guillotine, increasing the contact pressure at the contact to overcome the repulsive electric force at the contact, to prevent contact of the welding, improving the dynamic and thermal stability.

IV. Ordering Information

Ordering instructions: product type, name, installation (not indicated by the first delivery) and the required number.

Actuator matching supply with isolation switch, but can also be ordered separately.

Products manufactured without auxiliary switch, if need be ordered separately.
