Technical field
The utility model relates to the transformer equipment technical field, is specifically related to a kind of power transformer.
Background technology
Power transformer is a kind of static electric equipment, is to become the equipment of the another kind of or voltage (electric current) that several numerical value is different that frequency is identical for the alternating voltage by a certain numerical value (electric current).Power transformer is one of capital equipment of power plant and electric substation.The effect of transformer is many-sidedly can not only deliver to the electricity consumption area to electric energy by boosted voltage, can also be lower voltage use voltages at different levels, to meet the needs of electricity consumption.In a word, boost and all must be completed by transformer with step-down.Transmit in the process of electric energy in electric power system, will inevitably produce voltage and the loss of power two parts, when carrying same power, voltage loss and voltage are inversely proportional to, square being inversely proportional to of power loss and voltage.Utilize transformer to improve voltage, reduced the power transmission loss.Existing transformer device structure complexity, function is complete not, and its radiating effect and travelling performance all have much room for improvement.
The utility model content
The purpose of this utility model is for above-mentioned deficiency of the prior art, and a kind of power transformer is provided, and it has simple in structure, and perfect heat-dissipating is easy to move, and is convenient to about the characteristics with management.
The purpose of this utility model is achieved through the following technical solutions:
A kind of power transformer, comprise housing, be provided with fuel tank in housing, fuel tank is provided with oil discharging valve, described housing top is provided with oil conservator, oil conservator is fixed on described housing by bracing frame, oil conservator is provided with oil level gauge, the oil conservator below is provided with dehydrating breather, oil conservator one side is connected with pressure relief vent, pressure relief vent is connected with Buchholz relay, the top of housing is provided with bushing, low-tension bushing and shunting switch, the bottom of described housing is provided with ground plate, the bottom of described housing is provided with roller devices, the both sides of described housing are provided with handle, the top of described housing is provided with dismountable sunshading board.
Wherein, described housing is provided with card slot.
