Products Description

VS1-YB the oil snubber is a mechanical device used within the VS1 indoor high-voltage vacuum circuit breaker. Its primary function is to reduce mechanical shock during the tripping process and adjust the mechanical characteristics of the circuit breaker's opening motion through oil buffering. In vacuum circuit breakers, the oil snubber is typically located below the mechanism and consists of a snubber housing, a snubber spring, and snubber oil.

Oil Cup

What is the function of the oil cup in a VS1 circuit breaker?

The oil cup in a VS1 circuit breaker is a device used to store and supply lubricating oil.

The oil cup in a VS1 circuit breaker, also known as a grease cup or lubricating grease cup, primarily functions to stably store lubricating oil through its internal structure and deliver it to the lubrication points of the equipment when needed, via a specific method (such as manual squeezing or pneumatic pushing).

Specifically, the oil cup typically includes a storage chamber, an oil outlet, an adjustment mechanism (optional), and a sealing structure. During operation, as the equipment runs, the lubrication points consume a certain amount of lubricating oil. At this time, the lubricating oil in the oil cup, under the influence of gravity or external pressure, flows through the oil outlet to the lubrication points, achieving a continuous lubrication effect.
