Design Concept Of Gravity-assisted Disconnection Mechanism For High-voltage Disconnecting Switches

The operating mechanism of hv isolator should ensure reliable no-load disconnection. hv isolator switch does not have arc-extinguishing capabilities; its opening and closing are primarily used for visible circuit isolation and safety confirmation during maintenance. Therefore, the reliability and visibility of the mechanical action are far more important than high-speed arc extinguishing. Gravity-assisted mode simplifies the mechanical action to a process of geometric displacement and self-weight coordination. This is mentioned as a design trend in several outdoor high voltage electrical isolator product specifications, helping to reduce the number of complex transmission components.

To ensure the effective functioning of the gravity-assisted structure, the mechanism design must avoid load disconnection scenarios, limiting the disconnection process to no-load or minimal capacitive current states. isolator high voltage is mainly used in engineering practice to establish a clear disconnection point to ensure the safety of subsequent maintenance or switching operations. Its operating sequence and mechanical path are also considered in the design, thus incorporating gravity as part of the physical input for the disconnection action.
