Seismic performance evaluation and reinforcement suggestions for step voltage regulator

Seismic performance evaluation and reinforcement suggestions for step voltage regulator

1、 Seismic performance evaluation

1. Structural analysis: Stepped voltage regulators typically consist of key components such as three-phase autotransformers, three-phase on load tap changers, and automatic controllers. When evaluating their seismic performance, it is important to focus on the structural stability and seismic resistance of these components.

2. Test requirements: Refer to the relevant standards in the "Code for Seismic Design of Electric Power Facilities" to conduct seismic tests on the stepper voltage regulator. The experiment should include seismic wave inputs from different directions to simulate actual earthquake conditions and test the response and performance of the equipment under earthquake action.

3. Evaluation indicators: Evaluation indicators should include structural strength, seismic performance, insulation capacity, as well as displacement and deformation of key components. Through these indicators, the safety and stability of the stepper voltage regulator under earthquake action can be comprehensively evaluated.

2、 Reinforcement suggestions

1. Structural reinforcement: For key components of stepper voltage regulators, such as transformers and switches, supporting structures and reinforcement brackets can be installed to increase their structural strength and improve their seismic resistance. The reinforcement plan should be designed and calculated based on the specific situation of the equipment.

2. Insulation reinforcement: Ensure that the insulation performance of the equipment is not affected under earthquake action. Measures such as strengthening insulation materials and optimizing insulation structures can be taken to improve the insulation strength and shock resistance of equipment.

3. Wiring terminal reinforcement: Reinforce the wiring terminals to prevent loosening or breakage caused by earthquakes. Special terminal fixing devices can be used or the mechanical strength of the terminal can be increased.

4. Cooling system optimization: Ensure that the cooling system can operate normally under earthquake conditions, avoiding equipment damage caused by poor heat dissipation. Measures such as reinforcing cooling equipment and optimizing cooling pipeline layout can be taken.

5. Regular maintenance and management: After reinforcement is completed, the stepper voltage regulator should be regularly inspected, maintained, and managed. This includes regular inspections of the structural strength, insulation performance, and cooling effectiveness of the equipment to ensure long-term stable operation.

In summary, by evaluating the seismic performance of the stepper voltage regulator and taking corresponding reinforcement measures, the safety and stability of the equipment under earthquake action can be significantly improved, ensuring the normal operation of the power system.
