Abstract
A vehicle roof high voltage potential transformer for an electric locomotive and an electric motor car belongs to a high voltage lean oil transformer is comprised of a base frame, a covering cap, porcelain cover and a transformer core and is characterized in that the porcelain cover is connected with the main tank body of the transformer core comprising an iron core and a coil through the snap ring and the base frame; the casing space around the transformer core is filled with a high purity quartz sand and an insulating oil compound being treated; the upper part of the porcelain cover is provided with the covering cap, which is used for rainproofing and as a high voltage input terminal, and the internal space below the covering cap is arranged with a respirator; an antifouling boss is arranged on the lower side surface at the edge of the porcelain cover. The high voltage transformer is lighter, smaller and simpler than traditional oil immersed high voltage transformer, and is better than a resin cast dry-type transformer in the anti-blowing aspect, and in particularly is applicable to the high voltage resistant working condition on the vehicle roof of the electric locomotive and the electric motor car.
Description
Technical field
The utility model relates to a kind of electric locomotive and electric vehicles roof high voltage potential transformer, belongs to oil-poor type high voltage potential transformer class.
Technical background
For many years, the high voltage potential transformer that China uses in electric locomotive and elec. vehicle industry has two kinds, first tradition oil immersed type voltage transformer, and it two is dry-type voltage inductors of resin-cast.Though above-mentioned two kinds of high voltage potential transformers in use differ from one another, and the some shortcomings part is also respectively arranged.As traditional oil-immersed and high-voltage voltage transformer structure more complicated, the big troublesome maintenance of volume and weight, noise in service is big and windage is also big, thereby significant discomfort is used for the electric power novel electric power locomotive that running velocity improves constantly and the operating needs of elec. vehicle, resin-cast type dry-type voltage inductor, though be to emerge in large numbers along with organic material in recent years and a kind of new material high voltage potential transformer of developing, show through the utilization and operation of long-term changeable environment that but be installed in the locomotive roof danger in season cracking or blast is being deposited on this resin-cast type dry-type high-voltage voltage transformer road again.
Therefore develop and seek the novel locomotive roof transformer that can overcome above-mentioned two kinds of high tension instrument transformer defectives again rational in infrastructure, beyond doubt the expectation of manufacturer and applying unit.
Technology contents
This electric locomotive and electric vehicles roof high voltage potential transformer, by base (1), block (6), the insulator (5) and the transformer device heart (8) are formed, it is characterized in that described insulator (5) withholds into the main box of the transformer device heart (8) that an arrangement is made up of unshakable in one's determination and coil through clasp (3) and base, the glass sand and the capacitor oil compound (4) of treated mistake in filling in the transformer device heart (8) cabinet space on every side; The block (6) that plays rainproof effect and double as high pressure input terminal is being settled on the top of described insulator (5), and the interior body space under the block (6) is being settled respirator (7).
The downside of the shirt rim (10) of described insulator (5) is provided with antifouling boss (11).
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure: 1, base 2, seal ring 3, clasp 4, quarz sand and oil 5, insulator 6, block 7, respirator 8, the transformer device heart 9, input terminal, 10 shirt rims, 11 antifouling boss.
The specific embodiment
This electric locomotive as shown in the figure and electric vehicle roof high voltage potential transformer, by base (1), block (6), the insulator (5) and the transformer device heart (8) are formed, withhold by clasp (3) member by insulator (5) and base (1) and to be integral, form the main box of transformer, in this main box, constitute the voltage transformer device heart (8) by unshakable in one's determination and coil and internal connection line, and be fixed on the base (1), this by the surrounding space of the transformer device heart (8) and main box in abrim through glass sand and a small amount of capacitor oil of special processing, described block (6) is placed in the top of insulator (5), porcelain cap (6) is gone up affixed input terminal (9), and respirator (7) is being set in the cavity under the porcelain cap (6); Downside in insulator (5) shirt rim is provided with the antifouling boss (11) that some roads play antifouling effect.
This voltage transformer is a self-cooled, the heat that produces in coil and the work unshakable in one's determination outwards distributes through quarz sand and insulator, be positioned at the intumescent respirator under the block, can be automatically and absorb very effectively or replenish the internal volume that causes because of temperature traverse and change, so can very prevent that effectively insulator from bursting problem; And the oil guard annex that has saved the sort of fuel tank of old-fashioned oil immersed type transformer, petrol storage tank and caused therefrom, as oil meter etc.In addition, the vehicle in the high-speed cruising makes the air-flow around this transformer, makes air-flow break-in speed change under the antifouling boss effect in the some roads of shirt rim downside, and it is dirty to help removing the ash that produces on the following insulator in shirt rim and deposit.
Claims (2)
1, a kind of electric locomotive and electric vehicles roof high voltage potential transformer, by base (1), block (6), the insulator (5) and the transformer device heart (8) are formed, it is characterized in that described insulator (5) through clasp (3) and base be pressed into the main box of the transformer device heart (8) that an arrangement is made up of unshakable in one's determination and coil, treated glass sand and capacitor oil compound (4) in filling in the transformer device heart (8) cabinet space on every side; The block (6) that plays rainproof effect and double as high pressure input terminal is being settled on the top of described insulator (5), and the interior body space under the block (6) is being settled respirator (7).
2, a kind of electric locomotive as claimed in claim 1 and electric vehicles roof high voltage potential transformer is characterized in that the downside of the shirt rim (10) of described insulator (5) is provided with antifouling boss (11).
