In recent years, it has targeted factoriesElectromechanical equipmentEnergy-saving renovations have gradually been widely applied, not only improving the output power and economic efficiency of enterprises, but also saving resources, promoting sustainable socio-economic development, and building a friendly environment. The article primarily provides a brief analysis and explanation of the energy-saving retrofit and application of factory electromechanical equipment.

1. The Meaning of Applying Energy-Saving Retrofit Skills for Factory Electromechanical Equipment

With the continuous development of China's mart-oriented economy, competition in the marketplace has become increasingly fierce. Factories face enormous pressure during production. On one hand, rising prices of power and raw materials have led to significant improvements in production costs. On the other hand, competition in the mall causes product prices to keep falling, which in turn shrinks the profit margins for companies. Therefore, energy-saving renovations in factories can effectively reduce production costs and greatly improve the economic efficiency of enterprises. In addition, China has already implemented energy-saving and emission reduction policies. If energy-consuming enterprises exceed limits or fail to meet government-mandated energy-saving targets, they will be classified as key energy-consuming enterprises and face fines or even suspension of business for rectification. Taking necessary energy-saving transformation measures is of great significance for the healthy development of factories and enterprises.

2.1 Selection of energy-saving equipment

2.1.1 Energy-saving retrofit skills applied to lighting appliances

Although lighting appliances do not account for a large share of the total electricity in factories, their large quantity means that if energy-saving retrofit skills are applied to lighting appliances and their properties are optimized, the variety of energy-saving lamps will increase, and a significant portion of electricity consumption will be saved. In factories, an electronic ballast lamp that is lightweight, low-voltage, and quiet can also be used. Electronic ballast lamps feature low input power, significant energy savings, high safety, and long lifespan. The fibers emitted by energy-saving lamps have fog penetration capability, making them more convenient for users. Fluorescent lamps can deliver outstanding luminous power in application, thereby achieving energy savings. Therefore, factories should also select suitable energy-saving lighting equipment based on their needs and considering power conservation.

2.1.2 Application of energy-saving retrofit skills in motors

During factory operation, motors are indispensable for power supply. As important equipment, motors require energy-saving upgrades to reduce energy consumption and improve motor power. The YE3 high-efficiency motor uses high magnetic permeability, low-loss cold-rolled, non-oriented silicon steel sheets, which effectively reduce losses, save energy and are environmentally friendly, and feature convenient installation and maintenance, greatly improving operating power.

2.1.3 Installation of the inverter

To achieve excellent control of the communicator motor, the operating frequency of the motor power supply can be adjusted by the primary principle of utilizing microelectronics and frequency conversion skills. Nowadays, many factories use high-power power supply equipment during production, which leads to significant power waste. By choosing suitable frequency converters to replace valve control, the output power of the factory motor can be greatly reduced in line with the reduction in motor output. Installing inverters in factories not only allows for proactive motor adjustment but also effectively reduces the power consumption of electromechanical equipment, comprehensively improving the energy-saving skills of the factory's electromechanical equipment.

2.1.4 Select low-resistance cables and choose appropriate wire cross-sections

The quality of power transmission and the energy consumption during transmission are both determined by cable resistance, which is used to transmit power between various electrical devices. The greater the cable resistance, the slower the transmission speed of power in electromechanical equipment, resulting in more energy consumption. Therefore, choosing cables with lower resistance can reduce heat dissipation and damage to transmission lines. The conductor cross-section should also be appropriately selected, which not only saves costs, energy consumption, and investment, but also increases factory revenue.

2.2 Energy-saving retrofit of the factory's power supply and distribution system

Energy-saving retrofit technology is well applied in power supply and distribution systems. Optimizing energy-saving design in power supply and distribution systems can promote the normal operation of factory electromechanical equipment and ensure stable working functions in production equipment, providing outstanding guarantees for product quality and power. 2.2.1 Rationality of Supply Voltage Rational electricity use also reflects the rational selection of supply voltage. This involves comprehensively considering factors such as equipment capacity, power supply intervals, quality status, and local grid safety. Of course, the nature of users' electricity usage should not be overlooked. When most users have equipment voltages at 6kV and have large capacities, if the equipment is economically suitable, a 6kV supply voltage can be selected. This helps reduce electricity consumption and achieves the goal of energy savings.

2.2.2 Application of Energy-Saving Transformers

In the transmission and transformation industry, transformers are the primary method of consuming electricity. According to relevant surveys and data, at that time, transformers in China accounted for about one-tenth of the total electricity generation in the entire power system. This accelerates the development and implementation of energy-saving transformers to reduce losses in the power supply and distribution system, and comprehensively advances the energy-saving retrofit skills of factory electromechanical equipment.

2.2.3 Expand reactive power compensation equipment to drive improvements in factory power factor

For estimating the electricity consumption of factory electromechanical equipment, the power factor of the factory appliances is the most important goal. Continuously increasing the power factor can improve the power usage of electrical equipment. Installing many reactive power compensation devices in factories can improve reactive power compensation. Reactive power compensation equipment enables the capacity of electrical equipment and transformer/distribution equipment to be utilized more fully, promoting improvements in equipment utilization and power consumption. Improvements in power output reflect reductions in the factory's electromechanical equipment electricity consumption. Installing client-side reactive power compensation devices can provide users with better service and promote their enjoyment of high-quality electricity.

2.3 Refined handling of electricity metering

Refined management is primarily reflected in monitoring the operating status of factory electromechanical equipment and critical electric energy metering devices, followed by regular follow-up investigations, which enables more scientific data analysis on the quality of power metering equipment. Potential risks in electricity metering within the enterprise have also been effectively prevented, and the accuracy of the factory's electromechanical equipment in energy metering has improved, further enhancing the factory's operating power. Formulating a long-term mechanism for electricity metering, which guides electromechanical equipment with similar plans to implement energy metering.

2.4 Use "peak shaving and valley filling" to save electricity costs

During factory production, there are obvious peaks and lows in electricity demand, generally characterized by high electricity consumption during the day and lower electricity consumption at night. Plant electrical can use the peak-valley effect to balance supply and demand at power plants. The primary implementation method is to transfer the electricity during peak consumption periods to the off-peak period. This is called "peak shaving and valley filling," which allows factories to balance electricity consumption during different periods. Since electricity prices differ between peak and off-peak periods, this saves a lot of electricity costs and effectively reduces the company's production costs, serving as an important means to improve factory output efficiency.
