In case of an emergency, such as a large leakage of the SF6 distribution GIS device, evacuate the site immediately and start all exhaust fans to exhaust air. Only after sufficient natural exhaust or forced exhaust, with a leak detector to measure the SF6 gas qualified, with the instrument to detect the oxygen content (not less than 18%) qualified, personnel are allowed to enter. When the explosion-proof film of the equipment breaks, it should be treated with power failure and wiped clean with ga

(1) SF6 gas has been widely used in the power industry because of its excellent insulation properties and arc extinguishing performance. The application of SF6 gas can not only improve the safety and reliability of power station operation, but also reduce the volume of electrical equipment, reduce the weight, reduce the cost, extend the life and maintenance cycle. However, SF6 gas will generate toxic and harmful substances under certain conditions, threatening the safety of personnel and equipme

WINFOSS-A21-3I series SF6 density relay calibration three-way valve is mainly used in the power industry with SF6 gas as the arc extinguishing medium of high pressure equipment, through the operation of the handle knob on the three-way valve, to achieve the three-way valve and the equipment body gas path, off. Thus, the aeration and replenishment of the equipment body and the on-line calibration and replacement of SF6 density controller are realized.

SF6 molecule has strong electronegativity, which makes SF6 have strong arc extinguishing ability. Because SF6 molecules become negative ions after adsorption of free electrons, negative ions are easy to combine with positive ions to form neutral molecules, so that the electrical conductivity of the arc space quickly disappears. Especially when the arc current is close to zero, this effect is more significant, and SF6 gas blows the arc, making a large number of fresh SF6 molecules constantly in c
