Static power compensator is controlled by the thyristor switching reactor and capacitor composition, because the thyristor response to the control signal is very fast, and the number of times can also be unrestricted.
The rapid development of the world economy and fierce competition make energy consumption growth accelerated, the resulting environmental problems are becoming increasingly serious.
In recent years, the rapid development of electronic technology, with the electronic devices of high-frequency, high-speed and integrated circuit-intensive and miniaturization, modular assembly, electronic components per unit volume of heat increased rapidly.
Variable voltage (VVVF) has a steady state control characteristics, and has good dynamic performance, can be comparable with the DC speed control system, widely used in rail transit locomotive traction and speed control system. However, with the increase in inverter power, its heat is also a substantial increase in the stability of the inverter to become an important factor in the use of stability.
In order to effectively cool the device, the heat in the space is transmitted to the external environment, and the heat pipe is used to change the heat Heaters become a first choice.
