Abstract
The utility model relates to a cabinet type active power filter compensating device, which comprises a contactor (1) arranged on a mounting frame in a box body, a cabinet door fan (2), an electrolytic capacitor (6), an IGBT component (7), a cooling fin (9), a cooling fan (8), a circuit breaker (12) and a filtering plate (13); and a radiator is formed by the cooling fin and the cooling fan. The active power filter compensating device is characterized in that the radiator is a heat-pipe radiator including the cooling fin (9) and a heat pipe (10) arranged at the middle part of the cooling fin; and the cooling fan (8) is arranged on one side of the cooling fin (9), and the other side thereof is connected with a cooling air duct (11) with an air outlet directly arranged outside a cabinet body (4). The device has the advantages that the heat energy is generated by all electronic components device in a cabinet; as the heat-pipe radiator has efficient and rapid heat exchange performance and a cold air source is provided by the cooling fan in time, overheated air in the cabinet can be ideally discharged and the device ensures that all the electronic components in the cabinet can normally run for a long time.
Description
Technical field
This use is novel to relate to a kind of filtering compensation device, and especially a kind of active power filtering compensation arrangement belongs to the electric filtering equipment class.
Background technology
Along with the extensive use of power electronic equipment, the harmonic pollution in the electrical network is also serious day by day.The power factor of many power electronic equipments is very low, also brings added burden and influences power supply quality to electrical network.As seen harmonic carcellation pollutes and improves power factor, has become an important field of research in power electronic technology transformation and the innovation.Solve the harmonic pollution of power electronic equipment and the basic ideas of low power factor problem and have two: (1) installing compensation arrangement, to compensate its harmonic wave and reactive power; (2) power electronic equipment itself is improved, make it not produce harmonic wave, and consume reactive power not, or as required its power factor is controlled.Therefore, to have become be one of important composition equipment of operation power equipment to filtering compensation device.But, element in the present compensation arrangement that uses, no matter be to adopt thyristor or powerful IGBT inverter, this device that is in operation all can produce bigger heat, though in the filtering compensation device that uses that comes out, also adopted various radiating modes to dispel the heat, but because there are certain defective in the mode and the concrete structure aspect that adopt, radiating effect does not still allow this device to work long hours under rated condition, and the service efficiency that this device itself exists is low, cause the user to calculate easily, type selecting makes the defective of misreading still not be solved.
The utility model content
The purpose of the present utility model: be intended to propose a kind of more filtering compensation device of great heat radiation effect that has, assurance device reaches the long-term safety operation under the rated condition.
This cabinet type active power filtering compensation arrangement, form by being located at the contactor on the installing rack in the casing, the mechanical, electrical electrolysis condenser of cabinet tradition of a family, IGBT element, fin, cooling fan, circuit breaker, filter band, constitute radiator by fin and cooling fan, it is characterized in that: described radiator is the heat-pipe radiator that is made of fin and the heat pipe that is placed in the fin middle part, one side of described fin is provided with cooling fan, and its opposite side is then connecting air outlet and directly placing the outer heat dissipation wind channel of cabinet.
This cabinet type active power filtering compensation arrangement according to above technical scheme proposition; because hot pipe technique directly is applied in the direct heat radiation of high-power IGBT; therefore; not only for the heat energy that produces in the timely reduction high-power IGBT operation process; the operational environment of protection IGBT has well usefulness, also provides technical guarantee for the long-time running under rated condition of this device simultaneously.This device solves the heating problem of active power filtering compensation arrangement, make the filter of same size can export bigger filtering compensation electric current, promptly adopt the filter behind this radiating mode to have bigger output capacity, improved the operational efficiency and the filtering compensation effect of device than the former filter of same specification.

Among the figure: 1-contactor 2-cabinet tradition of a family machine 3-external reactance device 4-cabinet 5-internal reactance device 6-electrolytic capacitor 7-IGBT element 8-cooling fan 9-fin 10-heat pipe 11-radiator air passage
Embodiment
This cabinet type active power filtering compensation arrangement as shown in the figure, it is a kind of improvement to the existing cabinet type active power filtering compensation arrangement of congenerous, this cabinet type active power filtering compensation arrangement, by being located at the contactor on the installing rack 1 in the casing, cabinet tradition of a family machine 2, electrolytic capacitor 6, IGBT element 7, fin 9, cooling fan 8, circuit breaker 12, filter band 13 is formed, constitute radiator by fin and cooling fan, it is characterized in that: described radiator is the heat-pipe radiator that is made of fin 9 and the heat pipe 10 that is placed in the fin middle part, one side of described fin 9 is provided with cooling fan 8, and its opposite side is then connecting air outlet and directly placing cabinet 4 heat dissipation wind channel 11 outward.
Concrete cabinet inner structure is: on the lower framework contactor 1, cabinet tradition of a family machine and external reactance device 3 and internal reactance device 5 are set in the cabinet, be provided with and high-power IGBT element 7 on the top tank interior framework, settling the radiator of forming by fin 9 and heat pipe 10 on these high-power IGBT element 7 tops, the fin of this radiator one side faces cooling fan 8, and the opposite side of fin is close to heat dissipation wind channel 11; Circuit breaker 12 and filter band 13 also are being set on this external upper stand.
Above-mentioned this cabinet type active power filtering compensation arrangement, its work principle is: the heat energy that all electronic components produce in this installs cabinet in service, since heat-pipe radiator have efficiently, heat exchange performance fast, add the cold wind source that cooling fan in time provides, therefore can be that branch effluxes the overfire air in the cabinet ideally, guarantee electronic components all in cabinet operate as normal for a long time.
