High frequency thyristor
module is played a big role in the industry, however, we know how to protect the high frequency thyristor module, the answer to the question I believe most people are & other;
Not & throughout;
So, the next, small make up and you talk about the protection of high frequency thyristor module method: 1, high frequency thyristor module over-current protection if you want to compare his whole over-current protection, our advice is preferred to use internal template with over-current protection function.
Among them, the fast fuse is a simple and commonly used method: (
Quick fuse choice: (1) fuse rated voltage should be greater than voltage of the input module;
(2) the rated current of the fuse should be module 0 of the nominal input current.
Six times, according to the calculated value is a little bigger or choose the same current fuse.
Wiring methods: quick fuse in the module of input, output load.
2, high frequency thyristor module overvoltage protection of high frequency thyristor module with poor ability to withstand voltage, when the components on the reverse voltage exceeds its reverse breakdown voltage, even if the time is very short, can cause damage of component reverse breakdown.
If forward voltage more than high-frequency positive turning point voltage thyristor module, can cause high frequency thyristor module hard opening, it not only make the circuit work properly, and multiple hard opening device is turning to lower voltage, even lose forward blocking ability and damage.
Therefore must adopt overvoltage protection measures to restrain the high frequency thyristor module on overvoltage that may occur.
3, high-frequency thyristor module overheating protection when high frequency thyristor module in the current through, will produce a certain pressure drop, and the existence of the pressure drop will produce certain power consumption, the greater the current, the greater the power, the greater the heat.
If you don't put these quantity of heat quickly melted away, will seize the thyristor chip problem.
Therefore requires the use of monitor the insulation of the element.
More than 4, the current is 5 A high frequency of thyristor module to install the radiator, and to ensure that the cooling conditions stipulated in the.
In order to ensure the radiator with high-frequency thyristor module tube good contacts, 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 high frequency thyristor module adopts the overvoltage and overcurrent protection device.
6, to prevent high frequency thyristor module control very forward overload and reverse breakdown.
Above is for the protection of high frequency thyristor module method, have you learned?
Zhejiang rectifier co. , LTD. , the production of various kinds of specifications models of thyristor module, MTC thyristor modules, solid state relay module, rectifier bridge module, such as supporting the radiator products, sincerely look forward to the cooperation with various companies and procurement staff, provide affordable, quality and reliable electronic components.
