Abstract
The utility model aims at solving the problems that the drying time is long, the drying temperature is not enough, and the drying is not even in a self-adhesive transposed conductor coil dried in a common vacuum drying tank, and discloses a drying device for the self-adhesive transposed conductor coil with heated air circulation. The drying device comprises a vacuum drying tank with a steam pipeline and is characterized in that the vacuum drying tank is communicated with a heated air circulation device through a circulation upper pipeline and a circulation lower pipeline, which are respectively provided with a vacuum pneumatic valve.
Description
Technical field
The utility model relates to a kind of baking apparatus of tack transposed conductor coil.
Background technology
The continuous increase of the power transformer product separate unit capacity of making along with China, transformer coil more adopts the tack transposed conductor to carry out coiling at present.
The drying of tack transposed conductor coil carried out in conventional vacuum drying jar in the past, and heating up through 6 hours preliminary dryings makes that temperature reaches more than 95 ℃ in the drying jar, drying 48 hours continuously then, and required time reached more than 54 hours altogether.Because criteria thus the drying time is longer, have a strong impact on production efficiency, and, the temperature data that the thermocouple of arranging in the coil according to from drying the time is gathered, although furnace temperature has reached the parameter of technological requirement, coil temperature but is difficult to reach more than 95 ℃ of technological requirement always, and we find that coil temperature is substantially below 90 ℃ from the temperature data statistics, and can produce the uneven phenomenon of being heated inside and outside the coil, this makes the bond effect of tack transposed conductor be difficult to be guaranteed.
Summary of the invention
Tack transposed conductor coil is long at the criteria thus the drying time of conventional vacuum drying jar, drying temperature is not enough, drying is heated uneven problem, and a kind of tack transposed conductor coil baking apparatus with hot air circulation is provided in order to solve for the utility model.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of baking apparatus of tack transposed conductor coil, comprise the vacuum drying pot that is communicated with jet chimney, it is characterized in that, described vacuum drying pot is communicated with heated air circulation device by pipeline under pipeline in the circulation and the circulation, and pipeline and circulation are respectively arranged with the Pneumatic vacuum valve on the pipeline down in the described circulation.
In the such scheme, described heated air circulation device comprises a heater and a blower fan that is communicated with this heater, and the import of described heater is communicated with jet chimney by a control valve; Heater outlet is communicated with the vacuum drying pot by pipeline in the described circulation; The import of described blower fan is communicated with air, and the outlet of blower fan is communicated with the vacuum drying pot by pipeline under the described circulation.Be provided with 72 by-pass tubes in the described heater.
The utility model increases hot air circulation pipeline, blower fan and heater on former conventional vacuum drying tank base, open hot air circulating system in the preliminary drying temperature rise period, reach the temperature of technological requirement after, close hot air circulating system and change the vacuum drying stage over to.Use the vacuum drying jar of hot air circulation after preliminary drying heated up 6 hours, to reach furnace temperature more than 110 ℃ through test, coil temperature is reaching about 6 hours more than 95 ℃, change over to and vacuumize drying also not decline thereupon of coil temperature after the stage, and continue at the uniform velocity to rise, and remain on about 115 ℃, thereby make the time of continuous drying shorten to 18 hours by original 48 hours always.Long with regard to the criteria thus the drying time that has solved tack transposed conductor coil like this, drying temperature not enough, drying is heated inhomogeneous this three big problem.
Cut two sections tack transposed conductors of same material, peel off former insulation, wrap up A59DD crimped paper again, make between lead root and the root to be close together.Adopt two kinds of different drying technologies to carry out drying respectively.After drying finishes, confirm through taking crimped paper contrast lead apart: do not use hot air circulation to press the tack transposed conductor of old technology drying, though drying more than 54 hours but cohesive force is not strong, and the tack transposed conductor that uses the hot air circulation drying only drying 30 hours caking property very good.
The utility model has the advantages that: the criteria thus the drying time that has shortened the tack transposed conductor greatly, improved the cohesive force of tack transposed conductor, improve the drying quality of coil, reduced production cost and energy resource consumption, solved the bottleneck that restricts the production cycle because of the drying scarce capacity.Every power transformer product on average needs drying two stoves, can save criteria thus the drying time 48 hours, with per hour about 200 yuan drying cost calculation, cost-saved 9600 yuan of every power transformer product, if be in 100 high-power transformer products of whole year production, can be enterprise every year and save about 960,000 yuan of cost, economic benefit that it produced and social benefit are conspicuous.

Among the figure: 1, pipeline in the circulation; 2, steam electromagnetic valve; 3, Pneumatic vacuum valve; 4, control valve; 5, Pneumatic vacuum valve; 6, filter; 7, pipeline under the circulation; 8, jet chimney; 10, by-pass tube.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail:
As shown in Figure 1, a kind of baking apparatus of tack transposed conductor coil comprises the vacuum drying pot that is communicated with jet chimney 8, and jet chimney 8 is provided with steam electromagnetic valve.The vacuum drying pot is communicated with a heater by pipeline 1 in the circulation, is communicated with a blower fan by pipeline under the circulation 7, and heater and blower fan closely are communicated with.Pipeline 1 and circulation are respectively arranged with the Pneumatic vacuum valve on the pipeline 7 down in the circulation.The import of heater is communicated with jet chimney 8 by a control valve 4; Heater outlet is gone up pipeline by circulation and is communicated with the vacuum drying pot; The import of blower fan is communicated with air by an air cleaner 6, and the outlet of blower fan is communicated with the vacuum drying pot by pipeline under the circulation 7.
As shown in Figure 2, be provided with 72 by-pass tubes 10 in the heater, external steam enters heater and flows out after 72 steam pipework shuntings, makes that laterally the air-flow of process heater heats up rapidly.
Operation principle of the present utility model
When hot air circulation is started working, air is earlier by air cleaner 6, being installed in explosion-proof type centrifugal fan on the fan supporter forces in the vacuum drying pot and produces air motion, and this moment, vapours was also constantly by in the heater of hot air circulation, the thermal current of the vacuum drying pot of feasible process heater is further heated, when furnace temperature and coil temperature at the uniform velocity rise to the desired parameter of technology, close high vacuum pneumatic operated valve 3 and high vacuum pneumatic operated valve 5, hot air circulating system and vacuum drying pot system isolate, this moment, hot air circulation finished, the drying stage of vacuum step by step of beginning vacuum drying pot.
