The explosion-proof beta-liquid cooling R-shaped winding iron core transformer station for a mine is characterized in that a liquid seal partition board (12) is provided with a set of expansion contractors (5), an elastic adjustable partition board (4) is arranged between the liquid seal partition board (12) and a pinch plate (14) of a transformer body, and the primary terminal of the transformer is connected with a high voltage wiring nozzle (7) via the high-voltage switch cabinet (6); the secondary terminal of the transformer is connected with a low-voltage wiring nozzle (11) via a low-voltage distributing cabinet (1), and the transformer body, the high-voltage switch cabinet (6) and the low-voltage distributing cabinet (1) are assembled on a pulley with road wheels (10). The explosion-proof beta-liquid cooling R-shaped winding iron core transformer station for a mine is suitable for cutting and changing electricity in high explosive environments such as underground coal mine laneways.
Description
Technical field:
The utility model belongs to power transformer, is specifically related to but R type takeup type iron core transformer station (transformer) of a kind of flame-proof mine β liquid cooling
Background technology:
In the known technology, power transformer mostly adopts lamination oil immersed type iron core, and overall volume is bigger, and core interior magnetic field substep is uneven, and magnetic gap is big, and no-load loss is big, and temperature rise works online.The cold oil burning-point is low, and about 160 degree, in the large-capacity power transformer, it is on fire from explosion that arc spark and high temperature easily cause fuel oil usually, the infringement power equipment, as be used in mine laneway, in case ignite the down-hole explosion hazard gases, its consequence that causes will be more serious.The application also is to the further improvement of applicant in ZL01274757.2 number " flame-proof mine Wound core phase shifting transformer " patent of first to file.
Summary of the invention:
It is little that the purpose of this utility model provides a kind of volume, magnetic loss is few, temperature rise is low, good cooling results, the high burning-point cooling fluid cooling of the flame-proof mine that the operating state safety reliability is high, transformer station's (transformer) of R type takeup type core structure is in order to solve the highly effective and safe operation of flame-proof mine power distribution equipment.
The utility model is taked following technical scheme.
Flame-proof mine β liquid cooling but R type takeup type iron core transformer station includes high-tension switch cabinet, flame proof housing, R type takeup type core structure is set in the housing, R type takeup type iron core winding around, the transformer inner chamber pours into high burning-point β cooling fluid, the fluid-tight dividing plate is provided with one group of expansion constrictor, the expansion constrictor is used for the heat expansion overflow and shrinkage refluxes, and keeps β liquid at a safe pressure.Elasticity is set between fluid-tight dividing plate and the transformer body buckle adjusts dividing plate, elasticity is adjusted dividing plate and is adjusted with discharge layer volume-variation and keep certain pressure, when the liquid heat expansion is overflowed β liquid, enlarge volume, can make the return valve of overflowing liquid on the expansion constrictor flow back to the transformer inner chamber during cooling.Transformer just extremely connects the high-voltage connection mouth through high-tension switch cabinet; Inferior extremely through low-voltage distribution cabinet connection low pressure wiring mouth.
The utility model has tangible technique effect compared to existing technology.β cooling fluid, full name are the high burning-point liquid of Beta Fluid, generally adopt on the large-capacity power transformer abroad, and its burning-point is up to more than 300 degree.R type takeup type iron-core coil magnetic loss is few, and temperature rise is low.The expansion constrictor can effectively be adjusted β cooling fluid temperature rise pressure and change, and above-mentioned every technical measures make that the flame-proof mine volume of transformer is littler, and specific capacity is bigger, and security reliability is better.
Description of drawings:
Accompanying drawing 1 is but R type takeup type iron core substation structure figure of flame-proof mine β liquid cooling
Accompanying drawing 2 is a but R type takeup type iron core transformer station expansion constrictor structural representation of flame-proof mine β liquid cooling
Among the figure, 1-low-voltage distribution cabinet, 2-inspection hole, 3-flame proof housing, 4-elasticity is adjusted dividing plate, 5-β liquid expansion constrictor, the 6-high-tension switch cabinet, 7-high-voltage connection mouth, 8-β liquid cooling is but, the 9-coil, 10-road wheel, 11-low pressure wiring mouth, 12-fluid-tight dividing plate, 13-discharge layer, 14-transformer body buckle, 15-R type takeup type iron core.
Embodiment:
Below in conjunction with accompanying drawing the utility model is specifically described.Embodiment is used for illustrating of the present utility model, rather than the utility model is imposed any restrictions.
Flame-proof mine β liquid cooling but R type takeup type iron core transformer station includes high-tension switch cabinet 6, flame proof housing 3, R type takeup type core structure 15 is set in the housing, R type takeup type iron core winding around 9, the transformer inner chamber pours into high burning-point β cooling fluid 8, fluid-tight dividing plate 12 is provided with one group of expansion constrictor 5, expansion constrictor 5 is used for the heat expansion overflow and shrinkage refluxes, and keeps β liquid at a safe pressure.Elasticity is set between fluid-tight dividing plate 12 and the transformer body buckle 14 adjusts dividing plate 4, elasticity is adjusted dividing plate 4 and is adjusted with discharge layer volume-variation and keep certain pressure, when liquid cools, can make the return valve of overflowing liquid on expansion constrictor 5 flow back to the transformer inner chamber.Transformer just extremely connects high-voltage connection mouth 7 through high-tension switch cabinet 6; Inferior extremely through low-voltage distribution cabinet 1 connection low pressure wiring mouth 11.Transformer body and high-tension switch cabinet 6, low-voltage distribution cabinet 1 are assembled on the dolly that has road wheel 10, are convenient to the down-hole and move.
