It is braked frequently in rail traffic vehicles, braking energy is considerable, if can be subject to rationally to utilize must can generate good economy
Benefit.With greatly developing for domestic rail traffic, this demand just seems more urgent.
Subway energy feedback system, as current transforming unit, is needed according to energy flow whole using Three-phase PWM Voltage Rectifier
Switch between stream, inversion operating condition, it can be by extra regenerative braking energy feedback to AC network.The core group of subway energy feedback system
Part is exactly that subway can present power cell, and the performance of power cell directly determines the performance of entirely energy feedback system.Existing subway can be presented
Power cell volume is larger, and structure is not compact enough；Secondary control signal is generally easy the interference by a signal, and reliability is deposited
In certain hidden danger.
Utility model content
The purpose of this utility model, power cell can be presented by being to provide a kind of close-coupled subway, and cellular construction is compact, control
Signal is not disturbed, and is convenient for modularization assembling.
In order to achieve the above objectives, the solution of the utility model is: a kind of close-coupled subway can present power cell, wrap
Include Control card component, stack bus bar, IGBT unit, square resistance, radiator, wherein IGBT unit and square resistance are fixed
In spreader surface, stack bus bar is fixed on two groups of IGBT units, and Control card component is located at IGBT unit top；The lamination
Busbar haves three layers, current potential be direct current just, direct current is negative, exchange.
In above scheme: the Control card component includes Control card and a closed metal shell, the control
Board is located in closed metal shell.
In above scheme: the metal shell is with a thickness of 1mm-2mm.
In above scheme: the radiator is two, and two IGBT units are separately fixed at two spreader surfaces.
After adopting the above scheme, the utility model has the following characteristics that
(1) Control card component is located in a metal shell, and metal shell plays shielding action to outer signals interference,
Metal shell can play the protective action to Control card simultaneously；
(2) two groups of IGBT units realize electrical connection using stack bus bar, and laminated bus bar structure is simple, and collecting and distributing inductance is small,
Improve system stability；
(3) two IGBT units are separately fixed at two spreader surfaces, are placed on different from conventional all IGBT units
The same radiator, advantage be that interfering with each other for two IGBT unit heats can be reduced, and the design that can reduce radiator is difficult
Degree and manufacturing cost.
(4) stack bus bar haves three layers, current potential be direct current just, direct current is negative, exchange；Save space.
(5) entire power cell structure is compact, is conducive to transport.
