1、 Key points for maintenance of 10kV high-voltage switchgear
1. Daily maintenance and inspection
Regularly inspect and repair the switch panel during its daily operation, mainly to remove dirt, adjust the operating status, etc. The inspection cycle is usually seasonal
2. Planned inspection and maintenance
This inspection mainly involves disassembling the switch panel for repair, checking the circuit breaker inside the switch panel, conducting a preventive test on the primary equipment of the switch panel, and replacing it. The inspection cycle is usually one to two years.
3. Strengthen the status inspection of switchgear
Real time detection and control of the operating status of 10kV high-voltage switchgear, selection of the correct maintenance plan, use status maintenance to reduce power outage maintenance, ensure operation, and improve the reliability of the entire power supply network.
4. Continue to strengthen power outage management during maintenance and repair
In the process of repairing a 10kV high-voltage switchgear, continuous power outages are usually required, and the status of the switchgear is also changing during operation. This will affect power distribution. Due to the large number of switchgear, it is very difficult to schedule the distribution network. Necessary divisions should be made based on their importance to ensure the smooth and efficient operation of distribution network scheduling.
5. Ensure the safety of the inspection process
When maintaining 10kV high-voltage switchgear, various relevant standards and specifications must be strictly followed to ensure safety first. Reasonable and scientific responsibilities of relevant personnel must be guaranteed to ensure orderly maintenance.
2、 Precautions for Maintenance and Overhaul of 10kV High Voltage Switchgear
The maintenance methods for 1.10kV high-voltage switchgear include preventive regular maintenance, improvement maintenance, fault maintenance, and condition maintenance. For a long time, maintenance has been used as a means of identifying hidden dangers and eliminating obstacles. In the regular maintenance mode of 10kV switchgear in power supply enterprises, the pre test maintenance period for 10kV primary equipment is 3 years.
2. Condition based maintenance is a maintenance strategy for enterprises based on safety, reliability, environment, and cost, which involves equipment condition assessment, risk assessment, maintenance operation, and reasonable maintenance costs. This is a predictive maintenance that is planned before equipment malfunctions and performance drops to unacceptable limits. Timely and targeted maintenance of equipment can not only improve equipment utilization, but also effectively reduce maintenance costs.
3. It is essential to ensure that the switchgear is in a good operating environment. If the operating environment is harsh, it will affect the efficient operation of the entire switchgear, thereby increasing the resistance of the entire switchgear busbar and severely oxidizing the surface of the busbar. If the temperature is too high, it will also reduce the service life and insulation performance of the internal components of the switchgear.
4. When repairing and maintaining damaged switches, great attention must be paid. In addition, its operating environment and internal factors, especially the prolonged running time, affect its normal and efficient operation. Therefore, operation and maintenance personnel must recognize the necessity of strengthening inspection and maintenance during daily maintenance to prevent deterioration. Therefore, it is necessary to strengthen the moisture-proof and dust-proof work inside the switchgear, prevent small animals from entering the cabinet, enhance the rust prevention treatment of metal conductors inside the switchgear, especially for moving parts, strengthen lubrication inspection, check whether screws and nuts are loose or falling off, check the status of various components inside the high-voltage switchgear, and check whether there is condensation inside the switchgear.
In short, the operation of 10kV high-voltage switchgear is often affected by various factors, which will further affect its operational effectiveness and endanger the entire distribution department and personnel. It is necessary to attach great importance to the maintenance of 10kV high-voltage switchgear, comprehensively grasp the various contents and key points of maintenance of 10kV high-voltage switchgear, adopt the maintenance efficiency and effectiveness of voltage switchgear, ensure the normal and efficient operation of switchgear, and further ensure the stability of the entire power supply network.
