Abstract
The utility model discloses a novel high-frequency arc striking system which comprises a high-frequency high-voltage starting circuit, wherein the high-frequency high-voltage starting circuit is connected with a PWM control circuit, the PWM control circuit is connected with a signal drive circuit, the signal drive circuit is connected with an intermediate-frequency oscillating circuit, and the intermediate-frequency oscillating circuit is connected with an insulating booster output circuit. The high-frequency arc striking system has reasonable structure, adopts the newest PWM high-frequency oscillating control circuit and drive, omits high-voltage packs and traditional spark stand-offs which are used for a long time, and improves the working reliability of the high-frequency circuit.
Description
Technical field:
The utility model relates to a kind of high-frequency arc strike system.
Background technology:
The high-frequency arc strike system that is adopted in the at present general argon arc welding equipment by step-up transformer by rectification after to the electric capacity charging, forms by discharge of spark gap device and electric capacity again and shakes the generation high-frequency and high-voltage.And this high-frequency arc strike system applies usually because the spark gap device inevitably has a large amount of dust knots and gathers, makes the high-frequency arc strike system lose concussion in air cooling form argon arc welding equipment, causes the argon arc welding equipment not have the high-frequency and high-voltage fault.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the novel high-frequency arc ignition system that the functional reliability of high-frequency circuit is good.
Technical solution of the present utility model is:
A kind of novel high-frequency arc ignition system, it is characterized in that: comprise the high-frequency and high-voltage start-up circuit, the high-frequency and high-voltage start-up circuit is connected with pwm control circuit, pwm control circuit is connected with signal drive circuit, signal drive circuit is connected with the intermediate frequency oscillating circuit, and the intermediate frequency oscillating circuit is connected with the isolation boosting output circuit.
The utility model is rational in infrastructure, has adopted state-of-the art PWM higher-order of oscillation control circuit and driving, has abandoned long-term next high voltage package and traditional spark gap device, has improved the functional reliability of high-frequency circuit.
