Analysis of the interlocking of the chassis vehicle of the Timetric VS1 vacuum circuit breaker

Timetric Electric's VS1 vacuum circuit breaker, especially the trolley design, has an interlocking function between chassis, and this interlocking mechanism plays an important role in the power system. Let's discuss its interlocking principle and applicable occasions in detail:

Interlocking principle

The interlocking between the chassis of Timetric Electric's VS1 vacuum circuit breaker is based on the following principles:

 Mechanical interlocking: When one chassis (trolley) is in the working position, the other chassis cannot be shaken to the working position. This interlocking is achieved through a mechanical device to ensure that the same circuit breaker component is not in an operable state at the same time, avoiding misoperation and potential power system risks.

 Setting of clearance holes: In applications such as dual power cabinets, users can set clearance holes between cabinets, and use these holes to achieve the correct position and interlocking operation of the chassis.

Applicable occasions

Timetric Electric's VS1 vacuum circuit breaker chassis interlocking is generally used in the following occasions:

 Dual power cabinet: In a dual power cabinet, multiple VS1 vacuum circuit breakers are used to achieve the backup and main switching of the power system. The chassis interlock ensures that only one circuit breaker is in operation during the switching process, preventing two power supplies from being connected at the same time, thereby ensuring the stability and safety of the power system.

Three-lock and one-key system: In some applications, a three-lock and one-key system can be used to further enhance safety and operation management. This system usually includes mechanical interlocking, electrical interlocking and key control to ensure strict control and sequence of circuit breaker operation.

Features and Benefits

Enhanced safety: The chassis interlock system effectively reduces the risk of misoperation, especially in complex power systems such as dual power cabinets or occasions requiring high security protection.

Easy operation: Through mechanical interlocking and clearance hole settings, operators can easily operate and maintain circuit breakers without worrying about potential problems caused by opening or closing multiple circuit breakers at the same time.

Summary

Timetric Electric's VS1 vacuum circuit breaker chassis interlock system ensures safe operation and stable switching of circuit breakers in complex power systems such as dual power cabinets through mechanical interlocking and clearance hole settings. This design not only improves the reliability of the power system, but also reduces the risk of misoperation, and is one of the important safety measures in the power industry.
