Problems solved by technology
[0002] At present, the underwater arc technology uses a finite length soluble graphite electrode. When the electrode is melted, the arc will be extinguished. When the electrode is replaced, the arc needs to be ignited again. Due to the existence of water, it is difficult to ignite the arc underwater. Need to consume more processes
In addition, re-igniting the arc will cause low production efficiency and reduce the effective gas composition of gas production.

The invention discloses an underwater arc double-arc stable switch control system. The input pole of a harmonic processing unit is connected with an industrial power grid through a circuit breaker K and a wire, the output pole of the harmonic processing unit is connected with the input pole of a rectification conversion unit through a wire, the output pole of the rectification conversion unit is connected with the input pole of a pilot arc unit, a first electrode and a second electrode through wires, the output pole of the pilot arc unit is connected with a third electrode through a wire, the other end of the pilot arc unit is connected with the second electrode through a wire, and a power control unit is connected with the rectification conversion unit, the pilot arc unit, the first electrode and a servo motor through wires respectively. Arc blowout is not needed in the electrode replacement process, the process of repeated arc striking in the intermediate process is omitted, and production efficiency is improved. In the whole arc replacement process, stability of voltages and currents is kept, and stability of the system can be maintained.
Description
technical field [0001] The invention belongs to the technical field of underwater arc electrode replacement, and in particular relates to an underwater arc dual-arc stable switching control system. Background technique [0002] At present, the underwater arc technology uses a finite length soluble graphite electrode. When the electrode is melted, the arc will be extinguished. When the electrode is replaced, the arc needs to be ignited again. Due to the existence of water, it is difficult to ignite the arc underwater. More processes are required. In addition, re-igniting the arc will cause low production efficiency and reduce the effective gas composition of gas production. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the invention provides an underwater electric arc dual-arc stable switching control system, so that when the device replaces electrodes, the electric arc can continue to burn stably, and the production efficiency ...
