The invention discloses a heating device and method for front window glass. The heating device comprises an automatic heating contactor, a first auxiliary contact, a temperature control switch, an electric heater, a heating power supply and a control power supply, wherein the electric heater is installed on the front window glass and is connected with the heating power supply through the first auxiliary contact; the first end of the automatic heating contactor is connected with a high-voltage end of the control power supply; the second end of the automatic heating contactor is connected with the first end of the temperature control switch; the second end of the temperature control switch is connected with a low-voltage end of the control power supply, and the automatic heating contactor is used for controlling a first auxiliary contact point. The temperature control switch is automatically closed when detecting that the temperature of the external environment is lower than a first threshold value; at the moment, the automatic heating contactor is powered on from the control power supply to control the first auxiliary contact point to be closed, so the electric heater heats the front window glass under the action of the heating power supply; and therefore, fog or frost or even ice on the front window glass of the motor train unit can be automatically eliminated in time, inconvenience in driving is avoided, and the driving safety of the motor train unit is guaranteed.
本申请公开了一种前窗玻璃的加热装置和方法,包括自动加热接触器、第一辅助触点、温控开关、电加热器、加热电源和控制电源,电加热器安装在前窗玻璃上,通过第一辅助触点与加热电源连接。自动加热接触器的第一端与控制电源的高压端连接,自动加热接触器的第二端与温控开关的第一端连接,温控开关的第二端与控制电源的低压端连接,自动加热接触器用于控制第一辅助接触点。温控开关在检测到外部环境的温度低于第一阈值时自动闭合。此时自动加热接触器从控制电源得电,以控制第一辅助触点闭合,使得电加热器在加热电源的作用下对前窗玻璃进行加热。从而自动及时消除动车组前窗玻璃上的雾、或者霜、甚至是冰,避免行驶不便,保证动车组的行车安全。
