Several methods and measures of transformer energy saving

 

Transformer energy saving four measures, one, drop high altitude load loss

 

(1) the use of excellent functional silicon steel sheet or amorphous alloy sheet and step joint.

 

(2) improve the dead structure and process, reduce the process coefficient.

 

(3) do not stack the yoke, silicon steel sheet is not painted disposal, shear burr control in 0.02mm.

 

Two, reduce the load loss

 

(1) the use of oxygen free copper rod drawing wire with higher conductivity than electrolytic copper, improve the conductivity coefficient.

 

(2) Appropriate reduction of current density, improvement of insulation structure, the use of half oil passage, prefabricated insulation parts, winding complete transposition, winding all set, self-adhesive wire, self-adhesive paper, reduce insulation volume, improve the winding filling coefficient, reduce the size of the winding, the use of optimization design.

 

Three, reduce the loss of other components

 

(1) Improve the dead-core structure, control the leakage flux of the winding in the design, adjust the ampere-turn balance, so as to reduce the stray loss of structural parts such as the oil tank.

 

(2) replace the tubular radiator with corrugated tank, chip radiator, heat pipe, replace the old radiator with a new structure, improve the heat dissipation efficiency.

 

(3) Adopting reinforced plastic fan to improve efficiency and reduce noise.

 

(4) Magnetic shielding or electric shielding is used to reduce stray loss of oil tank, and non-magnetic materials are used as strapping parts or magnetic flux separators to increase stray loss.

 

Four, the application of task machine task characteristics to reduce loss

 

If the capacity changes synchronously with the size of the transformer load, eliminate or increase the "big horse car" scene, you can reduce the loss. Due to the change of load, the voltage of the task machine fluctuates between high and low, which makes the machine out of the efficient task area in many times. If the voltage is adjusted with the change of the load, so that the task machine has been adhering to the maximum efficiency, as far as possible to adhere to the three-phase current balance, eliminate or reduce harmonics, you can reduce energy consumption.

 

According to the above four measures can be consumed through improved material, component structure, task principle and other ways to save energy in a total of 4 categories of more than 20 kinds of transformer goods. With a combination of measures, energy savings could be even greater.
