At the same time, the over current and short were adopted to protect circuits and improve circuit reliability.
同时使用过流和短路保护电路，提高电路可靠性。
The over-current relay works to protect oscillation tubes and rectifier, when the current exceeds its limits. Frequency deviation caused by faulty operation is also prevented.
当电流超过限制值时，过负荷电流继电器自动保护振荡管和整流器，同时可以避免由不当操作所引起的频率漂移。
Characteristics: that amplifier take to press, over carry, protect over the electric current, and the large have fever the fan to add the stability work to guarantee the equipments long time.
特点：功放带压限、过载、过流保护，大型散热器保证设备长时间的稳定工作。
