Abstract
The utility model relates to a heat abstractor of power electronics type reactive compensation subassembly, include: comprises a shell (1) and a turbine fan (2) or an axial flow fan arranged on the shell (1); an air duct is arranged at the air outlet of the turbine fan (2) or the axial flow fan, and heat dissipation holes (3) are formed above the air duct; the radiator (4) is fixed in the shell, and air holes (5) are formed in the shell below fins of the radiator (4); a thyristor controlled silicon module (6) and a temperature controller (7) are fixed at the upper end of the radiator (4); the turbine fan (2) or the axial flow fan is connected with the temperature controller (7). The utility model discloses need to erect the radiator of power electronic switch and place completely and not allow exposing outside in the subassembly shell when structural design, from at the inside heat dissipation wind channel that forms of subassembly, then the installation fan is taken out the heat on with the radiator through the wind channel and is left the subassembly shell outside to reach the effect to power electronic switch forced air cooling.
Description
Technical Field
The utility model belongs to the technical field of an electric field and specifically relates to a heat abstractor of electric power electron type reactive compensation subassembly is related to.
Background
The traditional reactive power compensation equipment adopts a pure mechanical switch or a compound switch as a switch switching capacitor, although the structure is simple, the load has a plurality of inherent defects when compensation is carried out. The contact of the reactive compensation equipment has low action speed, reactive power generated by rapid and frequent fluctuating impact load can not be effectively compensated, and the phenomena of serious current inrush and operation overvoltage are often caused in the process of frequently switching the capacitor, thereby seriously influencing the service life of the device. Not only the compensation effect is not good, but also the potential safety hazard is easily caused. And although can solve above problem with power electronic switch's dynamic reactive compensation equipment as fling-cut switch, power electronic switch can produce a large amount of heats in the course of the work, these heats will cause power electronic switch to puncture the damage if lasting piling up and reach power electronic switch limit temperature, because do not have the power electronic type reactive compensation subassembly that forces the forced air cooling structure on the market, so to the heat dissipation problem of power electronic type reactive compensation subassembly, the urgent need for a power electronic type reactive compensation subassembly that the radiating effect is good on the market, the utility model provides a heat radiation structure of power electronic type reactive compensation subassembly.
SUMMERY OF THE UTILITY MODEL
The above technical problem of the present invention can be solved by the following technical solutions:
a heat dissipation device for a power electronic type reactive compensation component is characterized by comprising: comprises a shell and a turbine fan or an axial flow fan arranged on the shell; an air outlet of the turbine fan or the axial flow fan is provided with an air duct, and heat dissipation holes are formed above the air duct; the radiator is fixed in the shell, and air holes are formed in the shell below the fins of the radiator; a thyristor controlled silicon module and a temperature controller are fixed at the upper end of the radiator; the turbine fan or the axial flow fan is connected with the temperature controller.
In the above heat dissipation device for the power electronic reactive compensation component, the heat dissipation holes are circular holes or elongated holes.
In the heat dissipation device of the power electronic reactive compensation component, the turbine fan or the axial flow fan is arranged at the top or the bottom of the heat dissipation device.
Therefore, the utility model has the advantages of as follows: 1. when the structure is designed, the radiator of the power electronic switch is required to be vertically arranged and completely placed in the component shell without being exposed outside, a radiating air duct is formed inside the component, and then the fan is installed to pump heat on the radiator out of the component shell through the air duct, so that the effect of forced air cooling of the power electronic switch is achieved. 2. Increase the flow of wind, do benefit to the circulation of air, reinforcing radiating effect can prolong equipment life, avoids the power electronic switch because the breakdown that the high temperature leads to damages, and the louvre can prevent that solid object from invading, prevents that people's finger from contacting live part or moving part in the shell.
