As we all know the soft starter's fever due to internal power loss, in the same way, but also for internal loss caused by fever.
So we usually install air cooled radiator in the soft starter, better send out quantity of heat.
In the interior of the soft starter, by thyristor
power loss and loss of power control circuit power loss of the two parts.
For low voltage soft starter, control circuit power consumption changes are relatively small, usually for decades.
As a result, the inside of the soft starter power loss is mainly composed of thyristor power loss.
When the capacity of the soft starter is larger, the heat generated in the thyristor power loss is ambassador tube core temperature rise rapidly, resulting in thyristor burnt out, therefore, must be taken to the heat generated by the soft starter sufficient send out.
This time we will install air cooled radiator.
Soft start internal loss is mainly produced by thyristor, and at the same time, the heat capacity of thyristor and the relatively small, therefore, the soft starter itself to the requirement of temperature rise depends on thyristor requirements for temperature rise.
Usually thyristor junction temperature requirements shall not be higher than 120 ℃, and reflect on the air-cooled radiator temperature generally shall not be higher than 75 ℃.
So using air cooled radiator the heat dissipation of soft starter to outside air.
Ensure good heat dissipation way often, don't be blocked.
It can more effectively scatter heat down and let the soft starter running better.
