Embodiment Construction

[0011] The power-concentrated EMU train water supply connecting plate includes a connecting plate body 1 with a length of 396 mm, a width of 53 mm, and a thickness of 27 mm. The center of the connecting plate body 1 is pierced with M12×1.75 fastening screws 2 from bottom to top. The connecting plate Both ends of the body 1 are processed with a 10mm thick concave platform, the upper surface of the concave platform is 12mm away from the upper surface of the connecting plate body 1, and the lower surface is 5mm away from the lower surface of the connecting plate body 1. The concave platform is vertically screwed with a total length of 91.3 mm along the water connection quick plug 3 symmetrically arranged in the center of the connecting plate body 1, the connection end of the water connection quick plug 3 ( figure 1 The upper end as shown) is 39mm away from the upper surface of the connecting plate body 1, the axis of the water connecting quick plug 3 is 22mm away from the end of t...

Abstract

The invention relates to water connection plates, in particular to a water connection plate of a train power supply cabinet of a power-centralized motor train unit. The problem that an existing trainpower supply cabinet water connection plate is not suitable for the water connection using environment between a train power supply cabinet power module and a water circulation system of the power-centralized motor train unit due to the fact that the existing train power supply cabinet water connection plate is limited by the mounting space and the self weight is solved. According to the scheme, the water connection plate of the train power supply cabinet of the power-centralized motor train unit comprises a connection plate body with a fastening screw being screwed at the center, concave tables are machined at the two ends of the connection plate body, water connection rapid plugs penetrate through the concave tables, and positioning guide columns penetrate through the inner sides of thewater connection rapid plugs. The water connection plate of the train power supply cabinet of the power-centralized motor train unit has the advantages that 1, the structural design is ingenious, andpositioning is achieved rapidly and accurately; 2, the water connection plate can be rapidly plugged in and pulled out, and is convenient to mount and maintain; and 3, the structural size and the selfweight meet the overall weight reduction requirements of power-centralized electric locomotives.

Description

technical field [0001] The invention relates to a water connection plate, in particular to a water supply connection plate for a centralized power train set. Background technique [0002] In the locomotive AC transmission system, the module needs to be connected to the water circulation system of the converter to complete the circulation of the coolant in the water cooling system and the module water cooling substrate, which is an important guarantee for the effective heat dissipation of the power module, safe and reliable operation. Therefore, the performance of the water connection plate is very important. It is the decisive factor to ensure the safe and reliable operation of modules and vehicle systems. [0003] In order to increase the speed of passenger transport on domestic main railway lines and ease the pressure on railways, a world-advanced AC drive passenger electric locomotive is needed to meet the requirements of main line passenger transport. The power-concent...
