Description
Technical field
The utility model relates to a kind of frequency conversion tank power cell structure, specifically a kind of medium voltage converter cabinet power cell using air-cooled radiator to carry out heat exchange.
Background technology
In medium voltage converter cabinet, power cell part is all the structure independent of cabinet, and cabinet internal heat generation device and power cell part are all complete heat exchange by blower fan, thus reach the object of heat radiation; As the core of medium voltage converter cabinet, be all generally only IGBT module and rectifier bridge are cooled during power cell design, miscellaneous part is if electric capacity, busbar are due to little relative to IGBT module caloric value and do not carry out heat radiation consideration.
And under practical operation situation, it is on-the-spot that service conditions is complicated and changeable adds that frequency conversion tank structure is airtight, the heat of IGBT module can not be taken away completely, power cell internal caloric value builds up, other devices of power cell internal such as stack bus bar, electric capacity also can generate heat simultaneously, when accumulation of heat to a certain extent time will affect the performance of DC support electric capacity, even damage device.
Summary of the invention
Technical problem to be solved in the utility model is, under traditional power cell uses wind-cooling heat dissipating condition, solve dominant loss part (IGBT module and rectifier bridge) and carry out radiating treatment simultaneously, make power cell internal form forced air cooling, reduce busbar, the heat of capacitor element body and the medium voltage converter cabinet power cell of minimizing power device damage.
In order to solve the problems of the technologies described above, medium voltage converter cabinet power cell of the present utility model, comprise housing, housing becomes two cavitys in left and right by baffle for separating, and one of them chamber is power cell room, TGBT module and rectification unit are installed above power cell room, be provided with radiator below TGBT module and rectification unit, TGBT module be provided with composite bus bar, composite bus bar installs Absorption Capacitance, another one chamber indoor location Support Capacitor, installs control circuit board above Support Capacitor.
The side of described Support Capacitor is also provided with control transformer.
After adopting above-mentioned structure, when power cell being thrown in when medium voltage converter cabinet is inner, because A, B, C three-phase is mounting arrangements from top to bottom, only need, at top, blower fan is installed, namely circulation wind path can be formed in frequency conversion tank inside, under IGBT module and the air-cooled condition of rectifier bridge, miscellaneous part comprises electric capacity, busbar etc. also can carry out heat exchange by circulating air cooling; Thus achieve power cell internal and form forced air cooling, reduce busbar, the heat of capacitor element body and the object of minimizing power device damage, its compact conformation, easy for installation, and it is more effective to make power cell internal device dispel the heat, wind medium voltage converter cabinet inside is made to form air-cooled circulation, decrease power cell device failure, reduce company's on-site maintenance cost.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model medium voltage converter cabinet power cell.
Embodiment
Below in conjunction with the drawings and specific embodiments, medium voltage converter cabinet power cell of the present utility model is described in further detail.
As shown in the figure, medium voltage converter cabinet power cell of the present utility model, comprise housing 1, housing 1 is divided into two chambers in left and right by dividing plate, one of them chamber is power cell room, TGBT module 2 and rectification unit 3 are installed above power cell room, TGBT module 2 is provided with composite bus bar 7, composite bus bar 7 is installed Absorption Capacitance 8, radiator 4 is provided with below TGBT module 2 and rectification unit 3, radiator 4 is for the heat exchange of IGBT module and rectification unit, and the heat radiation of whole right chamber simultaneously also mainly carries out heat exchange by radiator; Another one chamber indoor location Support Capacitor 5, that is separates Support Capacitor 5 and dominant loss device; Install control circuit board 6 above Support Capacitor 5, the side of Support Capacitor 5 is also provided with control transformer 9; When power cell being thrown in when medium voltage converter cabinet is inner, because A, B, C three-phase is mounting arrangements from top to bottom, only need, at top, blower fan is installed, namely circulation wind path can be formed in frequency conversion tank inside again, under IGBT module and the air-cooled condition of rectifier bridge, miscellaneous part comprises electric capacity, busbar etc. also can carry out heat exchange by circulating air cooling.
