Abstract

PURPOSE:To recover the function of a transmission tube, by switching a circuit from a DC high-voltage power supply giving normally a DC high voltage to the transmission tube of the transmitter itself to a circuit supplying the DC high voltage to the transmission tube via a current limit resistor, if grounding takes place frequently in the tube. CONSTITUTION:The DC high-voltage power supply 2 supplies the DC high voltage between a cathode K and a collector C of the transmission tube 1, a heater power supply 3 supplies power to a heater H of the transmission tube 1 and a grid power supply 4 supplies a grid voltage to a grid G of the transmission tube 1. If grounding takes place frequently in the transmission tube 1, relays 6, 7, 8 are operated, the connection between terminals of the power supply 3 and the heater H and the connection between the power supply 4 and the grid G are disconnected respectively to stop the supply of the heater power supply and the grid power supply and the circuit is changed over so as to apply the DC high voltage between the cathode K and the collector C via the current limit resistor 5.

目的としている。In a transmitting tube that operates with high DC voltage applied between the cathode and the collector, arcs within the tube may occur frequently. Conventionally, in this case, the transmitting tube was removed from the transmitting device, attached to a device equipped with a special current-limited high-voltage DC power source provided separately from the transmitting device, and the full DC high voltage from the power source was applied between the cathode and the collector. All work was being done to restore the functionality of the transmitting tube. This method had the disadvantage of requiring a special device, that is, an aging device. If arcing occurs frequently in the tube, the transmitting device itself switches the function of the transmitting tube so that high voltage DC is supplied to the transmitting tube from the high-voltage DC power supply that normally supplies high voltage to the transmitting tube via the current-limiting resistor. The purpose is to provide a complete transmitting device that can perform recovery operations.

ある。As described above, according to the present invention, it is possible to switch so that the DC high voltage is applied between the cathode and the collector from the DC high voltage power supply provided in the transmitting device itself via the current limiting resistor. If arcing occurs frequently in a transmitting tube, there is an advantage that all work to restore the transmitting tube's function can be carried out while the transmitting tube is attached to the transmitter.
