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 as a sealed structure, water
vapor, dust， harmful gases can not enter， so that 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, never dry, so that the kneaded torque after long-term operation of the isolation switch will not increase. Stainless steel shaft pin and oil-free self-lubricating bearing matching 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. The ordinary installation site should be free of gases, vapors, chemical deposits， salt spray, dust and other explosive and corrosive substances that seriously affect the insulation and conductivity of the isolation switch;

7. Ati-pollution type is suitable for heavy pollution areas, but should not cause fire and explosion substances.
