Abstract
The invention discloses a baking method, aiming to provide a method for heating and baking a reactor product with high baking efficiency and cost-saving performance. The method provided by the invention comprises the following steps: connecting a harmonic generating source to the reactor product, and introducing harmonic current to a coil of the reactor product; monitoring the temperature of an iron core and the coil in the reactor product in real time by a temperature-measuring instrument; cutting off the current source of the harmonic generating source when the temperature of the iron core and the coil in the reactor product is detected to reach a given temperature; baking the reactor product processed in the above steps in an oven, and finally taking out the reactor product. The method provided by the invention can be widely applied to the field of reactors.
Description
Technical field
The present invention relates to a kind of method to the baking of reactor product by heating.
Background technology
The reactor product need carry out heated baking to remove the inner moisture of product before impregnated insulating paint.Need carry out heated baking insulating varnish behind the impregnated insulating paint makes insulating varnish solidify.Be applied to the reactor product on the wind-powered electricity generation project, its capacity and volume are increasing.Traditional method to the baking of reactor product by heating is: product is directly put into baking oven carry out heated baking.The shortcoming of this heating means is: the volume of product own is excessive, and the inner coil of product is wound on the iron core, and coil inside and inner iron core temperature rise slowly during heating, length consuming time.As: a net side 1.5MW reactor is warming up to 120 ℃ from 25 ℃ of room temperatures, needs 2～3 hours, continues one long period of heating then.This technology has greatly influenced the efficient of enterprise, has increased the whole enterprise cost indirectly.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes prior art, and a kind of method to the baking of reactor product by heating of toasting the efficient height, practicing thrift cost is provided.
The technical scheme that the present invention adopted is: the present invention is a kind of method to the baking of reactor product by heating, and this method may further comprise the steps:
(1) on the reactor product, inserts harmonic wave the source takes place, in the coil of said reactor product, feed harmonic current;
(2) adopt temperature measuring device to monitor the temperature of interior iron core of said reactor product and coil in real time;
(3) after the temperature of iron core and coil reaches design temperature in detecting said reactor product, cut off the current source that the source takes place said harmonic wave;
(4) the reactor product of handling the process above-mentioned steps is sent in the baking box and toasts, and takes out said reactor product at last.
Said temperature measuring device is an infrared thermometer.
The invention has the beneficial effects as follows: because the present invention adopts harmonic wave generation source to come reactor product inner iron core and coil are heated earlier; Utilize said harmonic wave generation source to produce harmonic current; Make iron core and coil produce a large amount of high-frequency losses respectively, reactor product self can promote temperature rapidly in the extremely short time, long time waiting when having avoided adopting the traditional heating method; Greatly improved baking efficient; Reduced production cost indirectly, and through test, this method there is not any harmful effect to product yet.

Fig. 1 is the flow chart of the inventive method;
Fig. 2 is that the brief structural representation that the source is connected with said reactor product takes place said harmonic wave;
Fig. 3 is the structural representation of said reactor product.
Embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, in the present embodiment, the present invention includes following steps:
(1) on the reactor product, inserts harmonic wave the source takes place, in the coil of said reactor product, feed harmonic current;
(2) adopt infrared thermometer to monitor the temperature of interior iron core of said reactor product and coil in real time;
(3) after the temperature of iron core and coil reaches design temperature in detecting said reactor product, cut off the current source that the source takes place said harmonic wave;
(4) the reactor product of handling the process above-mentioned steps is sent in the baking box and toasts, and takes out said reactor product at last.
In the present embodiment, design temperature is 120 ℃.Said harmonic wave generation source is a three phase harmonic generation source apparatus.After feeding harmonic current to the reactor product, said reactor product can be warming up to design temperature certainly in 60 seconds, and then sent into oven for baking.Compare with traditional baking method, the inventive method can promote baking efficient more than 30%, and the reactor product is not had any harmful effect.
Operation principle of the present invention is following:
The reactor product inserts harmonic wave the source takes place, and feeds the harmonic current of certain content then, and the iron core in the reactor product is operated under high frequency and the high-magnetodensity situation, and iron loss increases sharply, and promptly the iron core bulk temperature raises.Simultaneously, after the coil in the reactor product feeds harmonic current, because harmonic current contains a large amount of radio-frequency components, cause the coil copper loss to increase sharply, promptly the coil bulk temperature raises.In addition, adopt infrared thermometer to monitor iron core and coil temperature in real time, in case the temperature superelevation is quickened insulating material and worn out.
The present invention can be widely used in the reactor field.
Claims (2)
1. method to reactor product by heating baking is characterized in that this method may further comprise the steps:
On the reactor product, insert harmonic wave the source takes place, in the coil of said reactor product, feed harmonic current;
Adopt temperature measuring device to monitor the temperature of interior iron core of said reactor product and coil in real time;
After the temperature of iron core and coil reaches design temperature in detecting said reactor product, cut off the current source that the source takes place said harmonic wave;
Be sent to the reactor product of handling through above-mentioned steps in the baking box and toast, take out said reactor product at last.
2. a kind of method to the baking of reactor product by heating according to claim 1, it is characterized in that: said temperature measuring device is an infrared thermometer.
