Description

TECHNICAL FIELD

[0001] The utility model relates to electrical component technical field, specifically, relate to a kind of multilayer composite insulation structure of high insulation solid-encapsulated pole. BACKGROUND

[0002] Solid-encapsulated pole is a kind of key component for high-voltage switchgear, usually used in vacuum circuit breaker or load switch. It provides insulation and mechanical support by encapsulating vacuum interrupter and other conductive components in epoxy resin, while ensuring the reliability and safety of the equipment.

[0003] When solid-encapsulated pole is in use, an insulation cylinder is often installed on the outside of the solid-encapsulated pole to enhance the insulation performance of the side edges. The insulation cylinder is installed on the outer wall of the solid-encapsulated pole, which not only makes the appearance of the solid-encapsulated pole more beautiful, but also greatly improves the withstand voltage capability, making the use of the solid-encapsulated pole more secure. However, the existing insulation cylinder is generally directly installed on the solid-encapsulated pole for use. After the solid-encapsulated pole is energized, it will generate a certain amount of heat due to its high resistance. As a result, the solid-encapsulated pole will expand due to thermal expansion and contraction effect during use, and then contract after cooling. This repeated expansion and contraction of the insulation cylinder will cause fatigue, which may lead to the detachment of the insulation cylinder from the solid-encapsulated pole, greatly reducing its firmness.
