The power grid of the factory is small, and the mid-frequency spot welding machine has strange tricks. When receiving new projects and adding new welding equipment, everything is logical. When evaluating the equipment, it is suddenly found that the factory power grid is not enough. The cost of capacity expansion is too high and the cycle is too long. You can only use the equipment on the way; then you have to understand that new projects or expansion of capacity to increase welding equipment, intermediate frequency spot welding machine has a strange move.

The traditional power supply for spot welding machine is power frequency power supply, two-phase input and AC output, the primary current is large during operation, the voltage drop of the power grid is obvious, and the power factor is only 65%, which requires high factory power grid, otherwise it is difficult to weld normally Production; using the current mainstream mid-frequency spot welding machine, the input is three-phase, so that the voltage of the power grid is balanced, after the rectification, filtering, frequency up-conversion, inverter of the inverter box, and then through the rectifier output of the secondary diode of the transformer, the power The factor can reach more than 90%, and the final output is DC, which maximizes the conversion and use of energy to minimize the demand for the grid;

In the state of a small power grid, in addition to the use of intermediate frequency spot welding machines, you also need to make an article on production line control and welding process; the first is to use time-sharing control, so that multiple devices of the welding line are staggered and discharged because of welding Most of the time is between 0.1S-0.2S, which can basically be ignored in the overall welding beat, but the demand for the power grid is different from the sky. After using time-sharing control, the demand for the power grid by multiple welding machines is only equivalent In a welding machine; the second is to use a reasonable welding process, using a stronger specification rather than a super specification, such as adjusting the welding time from 25MS to 50MS, the welding effect is not greatly reduced, but its welding current The demand is only half of the original, and the demand for the power grid is only 60% of the original, which will greatly reduce the problem of the power grid.
