The efficient and safe use of power equipment depends not only on the performance and quality of the equipment itself, but also on the operator's in-depth understanding and scientific application of its characteristics and operating conditions. Mastering the system's usage techniques can reduce the risk of failure, extend equipment life, and optimize energy efficiency in daily operation, which is of great significance for ensuring the stability of the power system and improving the level of operation and maintenance management.
The primary technique lies in correct selection and reasonable configuration. Equipment with appropriate capacity margin and matching technical parameters should be selected based on the load characteristics, environmental conditions, and expected expansion needs of the power supply area. For example, in environments with high harmonic content, transformers and switchgear with strong harmonic resistance should be selected; in environments susceptible to moisture or corrosive gases, sealed and corrosion-resistant products should be given priority, along with dehumidification, ventilation, or air purification facilities. Avoid "overloading" the equipment to prevent no-load losses, and also prevent long-term overload operation that leads to excessive temperature rise and insulation aging.
Precise installation and wiring are fundamental techniques to ensure that equipment achieves its designed performance. The installation location should meet the requirements for heat dissipation, maintenance, and safety distance. The foundation should be stable and level to prevent structural deformation or internal component displacement due to mechanical stress. Electrical wiring must be strictly performed according to drawings and process standards to ensure correct phase sequence, secure terminals, and low contact resistance. Secondary circuit wiring should prevent open circuits, short circuits, and misconnections. The shielding layer and grounding wire should be arranged reasonably to suppress interference and ensure signal integrity. For oil-filled and gas-filled equipment, the sealing condition should be checked to prevent leakage from affecting insulation and arc-extinguishing performance.
Monitoring and control techniques during operation are crucial for real-time safety and energy efficiency optimization. The equipment's built-in indicating instruments, temperature monitoring, and alarm systems should be fully utilized to regularly record key parameters such as voltage, current, power, oil level, and gas pressure. Any deviations from normal ranges should be analyzed promptly, and adjustment measures should be taken. For inductive equipment such as transformers and reactors, attention should be paid to three-phase load balance to reduce additional losses and localized overheating caused by unbalanced current. For circuit breakers and contactors, frequent operation beyond their mechanical life should be avoided; soft starting or frequency conversion speed regulation should be used when necessary to reduce impact.
Maintenance techniques must be integrated into daily habits. Regularly inspect the equipment's appearance and connections, removing dirt and rust from insulation surfaces and metal parts. Lubricate, tighten, and clean according to the prescribed schedule, especially conductive circuit joints and rotating mechanisms, to prevent malfunctions caused by poor contact or jamming. For media such as insulating oil and sulfur hexafluoride gas, samples should be taken and tested according to regulations. If increased dielectric loss, excessive moisture, or abnormal decomposition products are found, address or replace them promptly. Maintain qualified spare parts and consumables in stock to ensure rapid replacement when needed, minimizing power outage time.
Operating and emergency response skills are crucial for preventing human error. Operators should be familiar with the equipment's working principles, control logic, and safety interlock functions, strictly adhering to operating procedures and work permit systems. Unauthorized live-line work or unauthorized modification of protection settings is prohibited. In the event of sudden abnormalities such as unusual odors, noises, smoke, or protection tripping, calmly determine the cause, isolate the faulty equipment according to the contingency plan, activate the backup circuit, and report the incident to avoid blindly restarting and expanding the scope of the accident.
Furthermore, utilize information technology and intelligent technologies to improve operational efficiency. By utilizing condition monitoring systems and inspection terminals, real-time data collection and trend analysis of equipment operation can be achieved, aiding in the identification of potential degradation and optimization of maintenance plans. Remote control and automation functions can reduce on-site operation frequency, improve efficiency, and lower personnel risks while ensuring safety.
In summary, the skills for using power equipment encompass selection and configuration, installation and wiring, operation monitoring, maintenance, safe operation, and intelligent applications. Only by combining standardized methods with accumulated experience, and forming scientific and meticulous operating habits, can equipment performance be maximized, ensuring the safe, stable, and economical operation of the power system.
