Embodiment Construction

[0040] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0041] Such as Figure 1 to Figure 5 As shown, a high-voltage equipment box for a railway passenger car is arranged in the equipment compartment under the rail vehicle for installing power receiving equipment.

[0042] Such as Figure 11 to Figure 14 As shown, the equipment box includes a box body 1, and the shape of the box body 1 is a cuboid, including a main frame 2 and a top plate 7 arranged on the main frame 2, a main side plate 8, a rear side plate, a metal through-tube mounting plate 11 and two The end plate 12, the rear side plate includes a side top plate 9 and a side bottom plate 10, and the main frame 2 includes a bottom frame 3, a top frame 4 and end frames 5 at both ends. The end frame 5 is square, the end plate 12 is welded on the end frame 5, the connecting frame 6 is fixed to the bottom frame 3 at the bottom of the end frame 5,...

Abstract

The invention relates to a high-voltage equipment box for a railway passenger vehicle. The high-voltage equipment box comprises a box body and electrical equipment which is arranged in the box body, wherein the bottom of the box body is level with a vehicle body bottom plate and becomes part of the vehicle body bottom plate. The bottom of the box body of the equipment box also serves as part of the bottom plate, so that the size of the box body can be increased greatly so as to meet the requirements of equipment in the box on electric clearance, and the leak tightness of an equipment cabin below the vehicle is guaranteed. The top of the box body extends above bottom girders, and yielding openings are obliquely formed in the bottoms of the two ends of the box body, so that the size of the box body is further increased. The leak tightness of the equipment box is enhanced through arranging wire clips and a filter; due to an arrangement manner for a box body main skeleton and various plates, the weight of the equipment box is effectively reduced, and the strength of the equipment box is improved.

Description

technical field [0001] The invention relates to an equipment box, in particular to a high-voltage equipment box for railway passenger cars. Background technique [0002] High-speed rail vehicles are generally equipped with a high-voltage equipment box, and the 25KV high-voltage power from the pantograph enters the traction transformer after passing through the vacuum circuit breaker in the high-voltage equipment box. At present, the minimum electrical clearance of vacuum circuit breakers and other equipment in the high-voltage equipment box is about 230mm, which only meets the OV3 overvoltage level requirements (GB / T21413.1), and does not meet the OV4 overvoltage level requirements (GB / T21413.1). [0003] For vehicles operating at high altitudes, the air pressure or air density decreases, and the external insulation strength decreases accordingly. The external insulation withstand voltage of electrical components needs to be corrected, and the electrical clearance of corresp...
