Abstract
The utility model relates to a high frequency and high voltage supply unit, which comprises a transformer, wherein the transformer is provided with a high voltage wire outlet terminal and a power component radiator. The unit is characterized in that the transformer is arranged on a base; a heat elimination fan is arranged in the base; the transformer is provided with a shield; a hanging electrical box is arranged on one side of the shield; a heat radiation air inlet duct is arranged between the back side of the transformer and the power component radiator; the lower end of the air inlet duct is connected with a blower, and the upper end extends to the head space of the transformer; air outlet ducts communicated with the head space are arranged on the left and the right side of the transformer respectively; air outlet holes are formed on the left and the right sides of the base respectively; and air inlet holes are formed on the front and the rear side plates of the base respectively. The supply unit can prevent the transformer and relative electrical apparatus elements from being damaged by a great amount of dust in dusty environment; and due to an airflow channel formed by the heat elimination fan, the heat radiation air duct and air outlet louver holes on both sides of the power component, the transformer and the power component can radiate heat so as to be cooled. In addition, the unit has a compact structure and can run steadily under high-temperature and dusty environment.
Description
Technical field
The utility model relates to a kind of high frequency and high voltage power supply device, particularly is applicable to the supporting high-power high-frequency high-voltage supply unit of electrostatic precipitator of large-sized boiler.
Technical background
In the past, the electrostatic precipitator that industrial large-sized boiler is used mainly is the power frequency electric cleaner, and along with progress of science and technology, requirement on environmental protection is more and more higher; The toxic emission of industrial large-sized boiler requires more and more stricter, and the power frequency electric cleaner can not be satisfied the demand, and high frequency electric source can overcome the deficiency of power frequency supply because of its high frequency characteristics, and its operating voltage is than high frequency electric source height, and control mode is more flexible; Because its operating frequency is brought up to 20000Hz from 50Hz, the volume of power supply self also reduces thereupon greatly; Reduced the expense of equipment and engineering, but general high frequency electric source can not adapt under the adverse circumstances of high cloud of dust gas and works.
Summary of the invention
The purpose of this utility model provides a kind of at the power high frequency high-voltage power apparatus, and it can be supporting with the high-frequency electrostatic deduster, still can steady operation under the adverse circumstances of power plant's high-temperature high dust flue gas.
High frequency and high voltage power supply device, comprise transformer, transformer is provided with high-voltage outlet terminal and power component radiator, said transformer is placed on the base, and cooling fan places in the base, the transformer guard shield of setting up defences, one side of protective cover is provided with the suspension electric appliance box, be provided with the heat radiation air inlet duct between the back side of transformer and the power component radiator, the lower end of this air inlet duct links to each other with blower fan, and the upper end feeds the headroom of transformer; The transformer left and right sides is provided with the exhaust passage that communicates with headroom, and the left and right sides plate of base is provided with vent, and the front and back biside plate of base has fresh air inlet.
The vent of base and fresh air inlet are each louvered hole.
Said protective cover is assembled by keel and detachable side plate.
Be provided with the internal air baffle of guiding left and right sides plate vent respectively from the lower end air outlet of exhaust passage, the left and right sides in the said base.
Outer wind deflector is equipped with in the outside of the left and right sides plate of said base.
Said transformer high-voltage outlet terminal stretches out from the front side board of protective cover.
The cooling fan outlet is connected with the lower end air inlet of transformer back side air inlet duct by a horn mouth.
This high frequency and high voltage power supply device can prevent that a large amount of dusts melt with relevant invading of electric elements transformer in the flue dust environment; Cooling fan sucks outside air from the louvered hole, both sides, front and back of base, air communication rises to the transformer top behind the air intake passage at the transformer back side, respectively to transformer and power component radiating and cooling, from entering the exhaust passage of the transformer left and right sides, discharge then from low seat two side air-out blinds holes.This apparatus structure compactness has solved the heat dissipation problem of transformer and power component, and this device still can steady operation under the environment of high-temperature high dust, and compact conformation is practical and attractive in appearance.
