35kv circuit breaker electrical equipment energy storage mechanical mechanism diagram

What is a 3ah35-se vacuum circuit breaker stored-energy module?

The type 3AH35-SE vacuum circuit breaker stored-energy module is designed to meet all applicable ANSI, NEMA, IEEE, and IEC standards. Successful application and operation of this equipment depends as much upon proper installation and maintenance by the user as it does upon the proper design and fabrication by Siemens.

What is a breaker operating mechanism?

igure 3/10.3.2 Structure of the breaker operating mechanism(Figures 3/4, 3/7, 3/8, 6/1 to 6/6, 7/1 to 7/5, 7/9, 7/10) The operating mechanism located in the housing substructure is of the s ored-energy spring type and acts on the three breaker poles. The necessary operating energy is stored ready fo

What is a type 3ah35-se circuit breaker?

Check for loose hardware. The type 3AH35-SE vacuum circuit-breaker operator is intended for stationary applications, such as the type SDV7-SE outdoor distribution circuit breaker. The type 3AH35-SE circuit breaker conforms to the requirements of IEC 62271-100 and ANSI/IEEE standards, including C37.04, C37.09, and C37.010.

What are the components of a circuit breaker?

The circuit breaker includes three vacuum interrupters, a stored-energy operating mechanism, necessary electrical controls and an operator housing. In a typical installation, insulating barriers may be located between the vacuum interrupters.

What is a vacuum circuit breaker operator module?

Figure 2: Vacuum circuit breaker operator module is a side view of the circuit breaker with the insulating barriers removed (if furnished) to show the vacuum interrupter, and the fixed-end and moving-end connection pads. All of these components must be clean and free of dirt or any foreign objects. Use a dry lint-free cloth.

How does a vacuum interrupter movable contact work?

The vacuum interrupter movable contact is connected to the flexible shunt associated with the other pole head and to the driving mechanism of the circuit breaker. The metal bellows provide a secure seal around the movable contact, preventing loss of vacuum while permitting motion of the movable contact along the axis of the vacuum interrupter.
