Description

Technical Field

[0001] This utility model relates to the technical field of generator tuning devices, specifically a tuning device for an impulse voltage generator. Background Technology

[0002] Currently, devices used in high-voltage, ultra-high-voltage, and extra-high-voltage lines need to undergo impulse voltage generator testing before leaving the factory to ensure their performance under normal use. Generally, impulse voltage generators are used for withstand voltage testing. During lightning impulse tests, the tuning resistor of the impulse voltage generator needs to be adjusted to ensure the impulse waveform meets the requirements of the standard. However, the tuning resistor needs frequent replacement during adjustment. In practice, the tuning resistor is connected using wiring, but this is time-consuming and inefficient. Using clamps to hold the resistor can lead to problems such as loosening of the clamps. Therefore, this paper proposes an impulse voltage generator tuning device. Utility Model Content
