The invention provides an electric appliance cabinet and a railway vehicle. The electric appliance cabinet comprises a cabinet body, an electric appliance part and a gas flame-retardant system, the cabinet body is of a sealed structure and is provided with an inner cavity, and the inner cavity is filled with flame-retardant gas. The electric appliance part is arranged in the inner cavity; the gas flame-retardant system comprises a gas inlet mechanism, a pressure acquisition unit and a control unit; the gas inlet mechanism is arranged outside the cabinet body, is in sealed connection with the inner cavity and is used for conveying flame-retardant gas into the inner cavity; the pressure acquisition unit is arranged in the inner cavity and is used for acquiring the internal pressure of the inner cavity; the control unit is connected to the air inlet mechanism and the pressure collecting unit and is configured to control the air inlet mechanism to convey air into the inner cavity when the internal pressure is smaller than a first pressure threshold value and control the air inlet mechanism to stop conveying air when the internal pressure is larger than a second pressure threshold value, and the first pressure threshold value is larger than atmospheric pressure; the second pressure threshold is greater than the first pressure threshold.

    本发明提出一种电器柜及轨道车辆,电器柜包括柜体、电器部件以及气体阻燃系统;柜体为密封结构并具有内腔,内腔中充注有阻燃气体;电器部件设置于内腔中;气体阻燃系统包括进气机构、压力采集单元及控制单元;进气机构设置于柜体外部并与内腔密封连接,用于向内腔中输送阻燃气体;压力采集单元设置于内腔中,用于采集内腔的内部压力;控制单元分别连接于进气机构和压力采集单元,控制单元被配置为:当内部压力小于第一压力阈值时,控制进气机构向内腔中输气,当内部压力大于第二压力阈值时,控制进气机构停止输气,第一压力阈值大于大气压力,第二压力阈值大于第一压力阈值。
