Selection of the rated voltage of the thyristor
medium frequency furnace, should refer to the actual working conditions of the size of the peak voltage, and set aside a certain margin.
Detailed to introduce the next note: 1, the selection of the rated current of the thyristor medium frequency furnace, in addition to consider through the components of the average current, also should pay attention to the normal work when the size of the conduction angles, cooling ventilation conditions and other factors.
At work should also pay attention to the pipe shell temperature not to exceed their electricity flow value.
2, before using thyristor medium frequency furnace, should use the multimeter to check thyristor medium frequency furnace are in good condition.
Found short circuit or open circuit phenomenon, should be replaced immediately.
3, it is forbidden to use megger (
The shaking table)
Check the insulation condition of components.
More than 4, the current is 5 a thyristor medium frequency furnace radiator is loaded, and the cooling conditions stipulated in the guarantee.
In order to ensure the radiator tube good contact with the thyristor module, between them should be coated with a thin layer of organic silicone oil or silicone, to help with good heat dissipation.
5, according to the rules of the main circuit of thyristor medium frequency furnace adopt overvoltage and overcurrent protection device.
The above is about the introduction of thyristor medium frequency furnace, but also to prevent the thyristor medium frequency furnace control very forward overload and reverse breakdown.
Thyristor medium frequency furnace true experts, in order to your satisfaction, we really heart.
If interested in our thyristor medium frequency furnace or there is doubt, welcome your consultation.
