Solid state high-frequency welder

Abstract

The invention discloses a solid state high-frequency induction welder comprising a power cabinet and a water system, wherein the power cabinet is integrated for integrating a power supply, rectification and inversion; and a power cabinet body comprises a left-side cabinet and a right side cabinet. The left-side cabinet mainly forms an inversion function and is responsible for inverting a direct current signal into a high-frequency signal and outputting. The right-side cabinet is internally divided into a front part and a rear part by a mounting plate; and the front part is mainly formed by a main loop and is responsible for rectifying the power frequency alternating current to form a direct current signal for inverting. A front panel of the mounting plate is sequentially provided with two parallel auxiliary power panels, four up-down stacked filter capacitors, three up-down stacked pulse transformers, a power supply buffer assembly, a voltage and current sampling plate, a pulse trigger plate and a silicon controlled controller assembly from left to right; and a rear panel of the mounting plate is a control panel which is respectively provided with an alternating current low-voltage control device and a direct current low-voltage control device. The water system comprises a water inlet pipe and a water outlet pipe which are respectively arranged in the front and at the back of the left-side cabinet.

AI Technical Summary

Problems solved by technology

[0004] 1. The long-distance transmission of high-power cables and the matching method of mechanical automatic loads are adopted, so the efficiency of the equipment is not high;

[0005] 2. Distributed power supply cabinets and inverter cabinets make the equipment bulky, so the workshop area occupied is relatively large;

[0006] 3. Decentralized layout makes high-frequency interference factors larger, which will affect welding quality
