Abstract

A linear electron beam tube adopts a programmable logic controller to precisely control the working current of a high-frequency welding machine. By setting a sampling resistor in the cathode circuit of the high-frequency oscillating tube of the fusion splicer, the voltage drop on the resistor is input to PLC or MCU, and the CPU in it calculates the cathode current value I according to Ohm's law. ca , the cathode current value I ca with the preset current value I ref The comparison is performed, and the compared difference is used to control the mechanical action of the high-frequency welding equipment. The method and the circuit designed according to the method can accurately control the high-frequency output current of the high-frequency welding equipment, and greatly improve the qualified rate of welded products of the high-frequency welding machine. At the same time, the design, installation and commissioning workload of the high-frequency fusion splicer using PLC or MCU is simple, the wiring circuit is simplified, the maintenance workload of the equipment is small, the maintenance is convenient, and the failure frequency of the equipment is further reduced.

Description

technical field [0001] The invention relates to an electronic tube, in particular to an electronic segmented electronic tube. Background technique [0002] At present, fluorescent lamps are widely used because of their energy saving and good luminescence, while electronic tubes are an indispensable device for daylight lighting. When starting (the moment when the starter is disconnected), the electronic tube will generate a higher self-inductance potential superimposed on the power supply voltage, so that the two ends of the lamp tube will get a higher starting voltage; after starting, it will act as a resistor The current coil is connected in series with the lamp tube so that the voltage across the lamp tube is reduced to the rated value. Ring tube fluorescent lamps are generally spliced ​​by several sections of fluorescent tubes. The existing electronic tubes are difficult to realize the conversion and control between multiple lamp tubes. Tube electronics Segmented tubes....
