GW9 24kV outdoor isolating switch

Overview

(H)GW9-10 type outdoor high-voltage isolation switch is an outdoor high-voltage electrical equipment with AC 50HZ, rated voltage class is 10kV, 15kV, 24kV for high-voltage lines to open and close without load, and for electrical isolation of high-voltage lines that are serviced by high-voltage bus bars, circuit breakers and other electrical equipment. It can also be used to open and close small capacitors or inductive currents.

This series of outdoor isolation switches meet the requirements of GB1985 "AC high voltage isolation switch and ground switch", 1EC60129 "AC . isolation switch and ground switch" and GB/T11022 "Common Technical requirements for High voltage switchgear and control equipment standards" and other standards.

Product Features

1. The isolation switch adopts the double-column center opening and contact turn-in structure, which has the ability of self-cleaning contacts and improves the contact reliability:

2. The rotating part of the isolation switch is designed to be maintenance-free. The rotating seat is designed to be a sealed structure where water vapor, dust and harmful gases cannot enter, making the bearing, lithium molybdenum disulfide based lithium grease will always work in a good environment. The shaft is not rusty, the grease can not be lost and never dry, so that the kneaded torque after long-term operation of the isolation switch will not increase. Stainless steel shaft pins and oil-free self-lubricating bearings match the structure; The parts are hot-dip galvanized to ensure that the isolation switch is flexible, lightweight, reliable and never corroded.

Normal operating environment

1. The altitude does not exceed 1000m;

2. Ambient air temperature: upper limit +40°C, lower limit -30°C in general areas, -40°C in high-cold areas;

3. Wind pressure does not exceed 700Pa, (equivalent to wind speed 34m/$3);

4. Earthquake intensity does not exceed 8 degrees;

5. Places without frequent and violent vibration;

6. Ordinary installation sites should be free of gases, vapors, chemical deposits, salt spray, dust, and other explosive and corrosive substances that can severely affect the insulation and conductivity of isolation switches;

7. The anti-pollution type is suitable for heavily polluted areas, but should not cause fire and explosive materials.
