â—Ž Ideal power factor Improving the power factor of the power grid is beneficial to the economic operation of the transformer.
◎ Reduce the operating temperature of the power transformer The temperature rise of the power transformer will be reduced by half for every 8 °C. If its operating temperature exceeds the allowable range of transformer winding insulation, the insulation ages rapidly and even breaks the windings, burning the transformer.
â—Ž Ignore the operation of the power transformer at the peak load. The peak load should be cut down, and the trough load should be increased.
â—Ž Maintain the three-phase load balance of the power transformer The three-phase unbalance of the power transformer, the maximum negative sequence current can not exceed 5% of the positive sequence current. If the transformer winding YO is wired, the current flowing through the neutral line should not exceed 25% Ie (Ie - the rated current of the transformer). If this value is exceeded, the loss will increase.
â—Ž Reduce or eliminate the high-order harmonics of the power supply system Various high-order harmonics, which are generated in any level of the power system, will cause power loss, and the power transformer is no exception.
◎ Changing the transformer Δ wiring to V wiring is one of the important means of economic operation. ◎ Reasonably distributing the load of the power transformer. For two or more transformers, the load distribution is different for the same capacity or different capacity. If the distribution is improper, the heavy load active loss is increased, the light load reactive loss is increased, and the power factor is deteriorated.
Motor operation energy saving â—Ž Ensure that the motor operating environment is good â—Ž Ensure that the motor temperature rise does not exceed the standard â—Ž Replace the loss of the motor â—Ž Replace the large capacity motor â—Ž Limit the number of motor starts â—Ž Reduce or eliminate the no-load operation of the motor â—Ž For the three-phase asynchronous motor Implementing static capacitor reactive power compensation and other measures to save energy
â—Ž Fans of large horse-drawn cars should be replaced with small capacity if conditions permit.
â—Ž Reduce running time as much as possible according to process requirements and weather temperature changes.
â—Ž Effectively control the air volume, such as adjusting the outlet damper, inlet damper and inlet blades to reduce air resistance.
â—Ž reduce static pressure.
â—Ž Check the pipeline network for leaks and plugging.
â—Ž Adjust the speed of the fan motor.
Energy-saving operation of the pump â—Ž Avoid large-size horse-drawn cars. For pumps with excessive capacity, replace the pump with the required capacity.
â—Ž Reduce the running time as much as possible according to the process requirements.
â—Ž Carry out water volume control, and appropriately reduce the flow rate by using valves, baffles, and the like.
â—Ž reduce static pressure.
â—Ž Properly connect the pumps in series or in parallel.
â—Ž Reduce the lift or reduce the number of operating units.
â—Ž For axial flow pumps and diagonal flow pumps, wing angle control can be performed over a wide range to improve efficiency.
