Improvement of Design Defects of Medium-wave TSD-50 Digital Transmitter
The medium wave digital AM transmitter TSD series has become the main model of medium wave transmitter.Compared with the original use of PDM models,digital transmitters of the electro-acoustic technical indicators are more excellent.And has a more complete variety of control,detection and protection systems,but despite this,in practice,there will be a lot of problems.To my station TSD-50 digital transmitter,for example,the machine has repeatedly appeared fan failure,high-voltage power supply cabinet of the main relay K2 and low-voltage power supply cabinet of the rectifier bridge stack are many times damaged and replaced,in order to completely solve the problem,in the exchanges with the manufacturer,to determine that these problems are due to design defects caused by.In this case,our technicians studied and analyzed the situation in depth,and carried out the improvement,this improvement solved the problem,and the effect is obvious.
