Grounding switches play a critical role in power systems, but contact welding problems often lead to equipment failures and compromise system safety. Welding typically occurs during frequent switching operations or when the current exceeds the rated value, causing a sustained short circuit between contacts. The resulting heat can lead to contact fusion.

To address this issue, the operating environment and procedures of the grounding switch should first be examined to ensure it operates within its rated limits. Regular maintenance and inspection of the contacts are essential. Any detected wear or oxidation should be repaired or replaced promptly. In addition, incorporating designs with overcurrent protection devices can effectively prevent contact damage caused by excessive current.

In practical applications, maintaining a proper operating frequency and implementing standardized maintenance procedures are key measures for reducing contact welding. These methods help ensure the reliability and efficiency of grounding switches.
