Abstract
The invention relates to a box-type transformer. The box-type transformer comprises a box body, and a high voltage chamber, a low voltage chamber and a transformer which are arranged in the box body, wherein the transformer is a dry transformer; a cooling blower is arranged below the transformer; the cooling blower is electrically connected with a temperature control device; the temperature control device comprises a controller, a temperature sensor and an electromagnetic valve; the temperature sensor is arranged on the transformer; the output end of the temperature sensor is connected with the input end of the controller; the output end of the controller is connected with the electromagnetic valve; and the electromagnetic valve is connected with the cooling blower. The temperature of the transformer is acquired by the temperature sensor and sent to the controller for analysis and processing, and the electromagnetic valve is controlled to turn on/off the cooling blower, so that the flexible control over the temperature of the dry transformer is realized, the running reliability of the dry transformer is improved, and the service life of the dry transformer is prolonged.
Description
Technical field
The present invention relates to a kind of power distribution equipment, relate in particular to a kind of box type transformer.
Background technology
Box type transformer is the complete distribution equipment that the on-load switch of transformer, high powered, low-voltage distribution equipment etc. are combined, and it has more than is transformer, is equivalent to a small-sized transformer station, directly to the user power supply is provided.Existing box type transformer divides Europeanly and American, and American volume is less, and load-bearing capacity is lower, and power supply reliability is not high, and European volume is bigger, and load-bearing capacity is all strong than American with power supply reliability, and in the general usefulness of China is that European case becomes.The volume that existing European case commonly used becomes is bigger, and not easy to assemble and long-distance transport is not suitable for some specific occasions; And if adopt oil-filled transformer, its type of cooling adopts transformer oil to cool off, and transformer oil is in operation and contacts with air; Quality of Transformer Oil can degenerate gradually, and the electric insulation degree reduces gradually, in use needs transformer oil is taked safeguard measure; Complex structure, cost are very high.
Summary of the invention
The present invention has overcome the deficiency of prior art, and the box type transformer that a kind of volume is little, can control temperature is provided.
For achieving the above object, the technical scheme that the present invention adopts is: a kind of box type transformer comprises casing, is arranged on hyperbaric chamber, low-pressure chamber and transformer in the casing; Said transformer is a dry-type transformer; The below of said transformer is provided with refrigeration fan, and said refrigeration fan is electrically connected with temperature control equipment, comprises controller, temperature sensor, electromagnetically operated valve; Said temperature sensor is arranged on the transformer; The output of said temperature sensor is connected with the input of controller, and the output of said controller is connected with electromagnetically operated valve, and said electromagnetically operated valve is connected with said refrigeration fan.
In preferred embodiment of the present invention, box type transformer further comprises and also comprises alarm lamp and the alarming horn that is connected with said controller.
In preferred embodiment of the present invention, box type transformer comprises that further the side of said casing is provided with a plurality of elliptoid louvres that are.
In preferred embodiment of the present invention, box type transformer comprises that further said temperature sensor is the PT100 platinum resistance thermometer sensor.
The invention solves the defective that exists in the background technology; The present invention gathers the temperature of transformer through temperature sensor; And the temperature of being gathered sent into analyzing and processing in the controller, the control electromagnetically operated valve is to the unlatching of refrigeration fan or close, and has realized the flexible control to the dry-type transformer temperature; Improve the reliability when dry-type transformer moves, prolonged the life-span of dry-type transformer.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Embodiment
Combine accompanying drawing and embodiment that the present invention is done further detailed explanation now, these accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, a kind of box type transformer comprises casing 1, is arranged on hyperbaric chamber 2, low-pressure chamber 3 and transformer 4 in the casing 1; Said transformer 4 is a dry-type transformer; The below of said transformer 4 is provided with refrigeration fan 5, and said refrigeration fan 5 is electrically connected with temperature control equipment, comprises controller 6, temperature sensor 7, electromagnetically operated valve 8; Said temperature sensor 7 is arranged on the transformer 4; The output of said temperature sensor 7 is connected with the input of controller 6, and the output of said controller 6 is connected with electromagnetically operated valve 8, and said electromagnetically operated valve 8 is connected with said refrigeration fan 5.
In the preferred embodiment of the present invention; Also comprise the alarm lamp 9 and alarming horn 10 that are connected with said controller 6; When the temperature of transformer 4 is higher than the caution temperature of setting in the controller 6, send warning light while alarming horn 10 through alarm lamp 9 and send chimes of doom, in time know transformer 4 operational environments of living in; Improve transformer 4 reliabilities of operation, prolonged the life-span of transformer 4.
For the ease of the heat radiation of transformer 4 in the casing 1, the side of said casing 1 is provided with a plurality of elliptoid louvres 11 that are.
The preferred said temperature sensor 7 of the present invention is the PT100 platinum resistance thermometer sensor,, and certainty of measurement is high, stable performance.
When the present invention works; In controller 6, set start-up temperature and a caution temperature of a refrigeration fan 5, utilize temperature sensor 7 to send the temperature of the transformer that collects 4 to controller 6, controller 6 compares the information that collects after analyzing and processing with the temperature of setting; When the temperature of transformer 4 is higher than design temperature; Controller 6 control electromagnetically operated valves 8 are opened, and refrigeration fan 5 starts, and transformer 4 is lowered the temperature; When the temperature of transformer 4 was higher than the caution temperature, controller 6 control electromagnetically operated valves 8 cut out, and sent warning light while alarming horn 10 through alarm lamp 9 and send chimes of doom.
Above foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm technical scope according to the claim scope.
