Analysis Of The Causes Of Component Damage Due To Forced Operation Of High-voltage Disconnect Switches

Because high voltage isolator switch is subjected to enormous electrical stress and mechanical pressure under high pressure. If the correct operating procedures are not followed during the operation of hv isolator, or if the switch is forcibly made without disconnecting the load, excessive mechanical impact or electric arc may be generated, which may damage the mechanical structure or electrical components of hv isolator switch. Especially in high voltage electrical isolator, which has not been maintained for a long time, components such as seals and springs may have aged, and forceful operation will accelerate their damage.
