Gas inlet system of gas turbine

The invention relates to the technical field of filtering equipment, in particular to a gas inlet system of a gas turbine. The gas turbine gas inlet system comprises a filtering unit, a safety unit and a monitoring unit. According to the technical scheme, the filter unit, the safety unit and the monitoring unit are arranged in the gas inlet system of the gas turbine, the safety unit is connected with the filter unit, and the safety unit can protect the filter unit to operate normally in severe weather; the monitoring unit is connected with the filtering unit, and the monitoring unit can monitor the filtering efficiency of the filtering unit. According to the air inlet system of the gas turbine, moisture, particles and the like in air can be effectively filtered, the condition of differential pressure over-limit alarm of the filtering unit can be prevented in severe weather such as ice blockage and humidity, the filtering efficiency of the air inlet system of the gas turbine in the actual operation environment
