The invention provides a CRH5A type EMU (electrical multiple unit) train electric heater test bed, belonging to the technical field of rail vehicle electric heater performance tests. The CRH5A type EMU (electrical multiple unit) train electric heater test bed comprises a test bed box body, also comprises a DC voltage stabilizing power supply, a contactor and a terminal block arranged in the box body, also comprises a temperature sensor, an electric heater pipe temperature test fixture, an electric heater and thermostat ground test fixture, adjustable power supply equipment and a small electric heater drying box arranged outside the box body, and also comprises a control switch, an indication lamp and a digital temperature measurement instrument arranged on a box body panel. The whole test bed is used for completing the power supply control in an electric heater test process, the power supply control in a temperature controller performance test process, and the temperature monitoring in an electric heater and temperature controller ground matching process. The CRH5A type EMU (electrical multiple unit) train electric heater test bed has the advantages of a simple operation, easy mastering by a user, simple accessories, low development cost and convenient maintenance, and the detection of an CRH5A type EMU train electric heater can be completed according to technical requirements under the condition of least resources.
Description
technical field [0001] The invention belongs to the technical field of rail vehicle electric heater performance inspection, and in particular relates to a CRH5A electric train set electric heater test bench. Background technique [0002] The electric heater is an important part of the rail vehicle, which plays a role in maintaining the temperature inside the vehicle in winter and satisfying the comfort of passengers. CRH5A EMU electric heaters include passenger compartment static heaters, porch static heaters, toilet static heaters, driver's cab console heaters, driver's cab static heaters and ventilation heaters. The first four are tubular heaters. , the latter two are integrated parts, which are composed of installation profiles, heat dissipation cover boards, electric heating tubes, temperature controllers and other electrical components. In order to control the surface temperature of the electric heating tube and prevent overheating, a thermostat is installed around the...
