New insulation technologies for medium-voltage circuit breakers primarily involve advanced insulation technologies applied to medium-voltage circuit breakers to improve equipment performance, reliability, and safety.
New insulation technologies for medium-voltage circuit breakers primarily include the following:
Encapsulated pole technology:
This technology encapsulates components such as the vacuum interrupter and insulating rod within an epoxy resin casing, forming a single, integrated insulation structure. This technology enhances insulation performance and improves pollution resistance. The use of fixed flexible connections also provides greater structural stability and reduces contact resistance.
Embedded-resin plate vacuum interrupter technology:
This technology embeds the vacuum interrupter within the resin plate, making the vacuum circuit breaker pole particularly robust and protecting the interrupter from impact, dust accumulation, and moisture. Because the arc extinguishing chamber contains no ionizable material, the arc generated when the contacts separate is composed entirely of molten and vaporized contact material. The arc is supported by external energy until the current disappears near its natural zero point. At this point, the load density rapidly decreases, and the metal vapor quickly condenses, resulting in a rapid recovery of dielectric properties.
Gas-insulated switchgear technology:
Gas-insulated switchgear technology utilizes gas-insulated cabinet-type switchgear, making it particularly suitable for urban power grids, railways, high-rise buildings, and locations with harsh environmental conditions. Gas-insulated switchgear is known for its compact footprint, minimal environmental impact, and high operational reliability.
Solid insulation technology:
Solid insulation technology is a new insulation technology developed to address the shortcomings of SF6 gas-insulated switchgear. Solid-insulated switchgear offers advantages in the medium-voltage sector, reducing or eliminating the use of SF6 gas, thereby minimizing environmental impact.
The above describes new insulation technologies for medium-voltage circuit breakers. The application of these technologies can improve the performance and reliability of medium-voltage circuit breakers while also contributing to environmental protection.
