Explosion-proof electric heater and railway vehicle with same

The invention relates to the technical field of heating equipment for vehicles, and particularly relates to an explosion-proof electric heater and a railway vehicle with the same. In the explosion-proof electric heater, an explosion-proof junction box is respectively connected with an explosion-proof electric heating pipe assembly and a resettable thermostat in an explosion-proof sealing way, the resettable thermostat is connected with the explosion-proof electric heating pipe assembly through a high temperature resistant wire so as to sense the temperature of the explosion-proof electric heating pipe assembly, and the explosion-proof electric heating pipe assembly is turned on or off according to the sensed temperature. The explosion-proof electric heater has an explosion-proof safety effect; in addition, full warm and half warm control can be also realized by vehicle wiring. By adopting an artificial resettable over temperature protector, when the temperature exceeds a set value, the over-temperature protec
