Strongly compressed air to extinguish the arc through arc area
Compressed air as the dielectric and insulating medium interrupter breakers. Strongly compressed air to extinguish the arc through the arc region, and as a pillar porcelain jacket chamber ventilation to keep the cavity dry. Compressed air is first
electri cenergy meter to a pressure of 15 ~ 20MPa, and then reduced to 2 ~ 3 MPa to obtain a relative humidity of 15% to 20% of the dry air, which can avoid the diurnal
Voltage stabilizer by 20 ~ 30 ℃ the saturation and precipitation moisture. Air circuit breakers usually interrupter, support structures and gas system components, can be divided into instantaneous inflatable, inflatable sub-gate, often inflatable and constant pressure of four.
