The invention discloses a train power supply device for an electric locomotive, which comprises: a main transmission system, which is used to provide traction kinetic energy for the locomotive and convert the kinetic energy of the locomotive into electric braking energy; an auxiliary converter system integrated in the main transmission system The traction converter is used to provide power for locomotive auxiliary equipment; the train power supply system is integrated in the traction converter of the main drive system to provide power for traction trains. The invention has the advantages of simpler structure of the whole machine, lower cost, good power supply effect and the like.

A household power supply device preventing electric shock to children comprises an upper case, a base, and two three-pole jack assemblies. Each three-pole jack assembly comprises a primary rotating case, a protective door, two single-pole jack assemblies for a flat insert of a plug to be inserted into, an unlocking ring, an unlocking rod, a first L-shaped conductive bar, a first copper bearing, a second copper bearing, and a third copper bearing. Each single-pole jack assembly comprises a secondary rotating case, a self-locking piece, a self-locking rod, a plug bush for a flat insert to be inserted into, a fourth copper bearing, a conductive connector, and a second L-shaped conductive bar. Due to the arrangement, the two rotating jacks in each three-pole jack assembly can rotate on the surface of a middle partition about the intersections of the two diagonals of rectangular openings thereof, so that both a three-pole flat plug and a two-pole flat plug can be inserted into the three-pole jacks, and the convenience in using the power supply device is improved.

An infrared calibration light source applied under vacuum and low temperature conditions. The infrared calibration light source mainly includes a casing and a mechanical installation interface, a blackbody radiation surface, a support structure, a vacuum packaging window, and a power supply line. The blackbody radiation surface is placed in a casing, and the casing The top of the body has a circular diaphragm above the black body radiation film, the black body radiation surface is parallel to the plane where the diaphragm is located, and the housing is provided with holes for passing through the power supply line. The outer surface of the housing has a higher emissivity, and the inner surface has a higher emissivity. Low emissivity, the side of the black body radiation film facing the diaphragm is used as the black body radiation surface, which has high emissivity and is used to emit infrared radiation; the other side of the black body radiation film has low emissivity, and the supporting structure adopts high temperature resistance and low thermal conductivity Made of high-efficiency ceramic material, the power supply circuit is used to supply power to the black body radiation surface, thereby controlling the temperature of the black body radiation surface.
