Primary circuit diagram

Harmonic-Free Solution

The secondary winding of the phase-shifting transformer employs an extended delta connection, altering the phase angle of each secondary winding per phase.

This mitigates the impact of harmonics generated by the unit on the power grid.
Taking two units connected in series as an example for analysis: the phase-shift angle o = 60°/2 = 30°
The current is referred to the primary input side and expanded into a Fourier series:

The 5th, 7th, and 11th harmonic components have phase angles differing by 180°, and through phase-shifting rectification technology, these harmonics cancel each other out.

Take the input phase-shifting transformer of a 10kv variable frequency drive (VFD) as an example. its primary winding is rated at 10kv, while the secondary side consists of 24 three-phase windings, each with an output voltage of 690v. Every winding adopts an extended delta connection and has a phase shift angle difference of 7.5°. This configuration can effectively eliminate harmonics below the 47th order, which means that 48-pulse rectification is capable of suppressing harmonics lower than the 47th order (calculated by the formula 6n-1, where n refers to the number of units per phase).

Frequently Asked Questions (FAQ)

1. What are the installation clearance requirements for the equipment?

The minimum clearance requirements are: at least 1500 mm from the front of the equipment to the wall, at least 1000 mm from the rear, at least 800 mm from either side, and at least 1000 mm from the top of the equipment to the ceiling.

2. How does the Harmonic-Free Solution protect the power grid?

By utilizing an input phase-shifting transformer with an extended delta connection, the phase shift angle differences cancel out low-order harmonics (such as the 5th, 7th, and 11th). In a 10kv VFD configuration, this effectively eliminates harmonics below the 47th order through 48-pulse rectification.

3. What is the standard overload capacity of these VFD units?

The standard overload capacity is 120% for 1 minute, allowed once every 10 minutes. Optional overload capacities of 125%, 150%, or 200% are available to meet specific application requirements.

4. Does the cabinet height in the selection table include the cooling fan?

No, the overall height listed in the model selection table does not include the height of the cooling fan. You should add an additional 300 mm to 600 mm for the total height calculation.

5. Can the system automatically restart after a temporary power failure?

Yes, the system features an auto-restart after power loss capability that allows it to safely resume operation within 20 seconds.

6. What redundant protection features are available?

The VFD supports several optional redundant designs to ensure continuous operation, including redundant control power supply, redundant power unit design (N+1), and redundant cooling fans.
