Mobile emergency air exhaust device for GIS equipment room and its application

Abstract

This paper introduces a mobile ventilation device that does not require construction and installation. It can be used in electrical equipment studios such as Gas Insulated Switchgear (GIS) filled with sulfur hexafluoride (SF6) gas. In the fault state of the ground exhaust device, the mobile ventilation device can quickly complete emergency forced ventilation and gas purification, and it can also be used for forced ventilation in laboratories, operating rooms and other places without preset ventilation systems. The mobile emergency air exhaust device can be placed at any time and in any place where ventilation is required, and it is inexpensive, safe, efficient, and versatile. In the SF6 leakage condition of the GIS equipment room, the ventilation efficiency can be increased over 97% in 10 minutes, and the adsorption removal rate of harmful components in the operating gas is higher than 90%.
