VS1(ZN63A)-12 side-mounted vacuum circuit breaker

Side-mounted vacuum circuit breaker The side-mounted indoor high-voltage vacuum circuit breaker is a three-phase AC indoor high-voltage switchgear with a rated voltage of 1,000 volts. As a protection and control unit for power equipment in power grid equipment, industrial and mining enterprises. The circuit breaker complies with my country's national standards "AC High Voltage Circuit Breaker", "Internal AC High Voltage Vacuum Circuit Breaker", "Indoor High Voltage Vacuum Circuit Breaker Ordering Technical Conditions" and related standards, and has a reliable interlocking function. The side-mounted indoor high-voltage vacuum circuit breaker can be operated frequently and has the capabilities of multiple openings and rapid reclosing. The indoor high-voltage vacuum circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body. It can be used as a fixed installation unit or assembled with a chassis truck to form a handcart unit.
Technical Description Performance and Structure Vacuum Circuit Breaker The switchgear is an air-insulated indoor switchgear component. The circuit breaker complies with the requirements of / and other standards. Under normal use conditions, as long as it is within the technical parameters of the circuit breaker, it can ensure safe and reliable operation in the power grid of the corresponding voltage level. The vacuum circuit breaker can perform frequent operations or break short-circuit current multiple times within the operating current range. The mechanical life can be up to 10 times, and the full capacity short-circuit current can be broken 10 times. Vacuum circuit breakers are suitable for reclosing operations and have extremely high operational reliability and service life. The ordinary type of vacuum circuit breaker uses a vertical insulating cylinder to protect it from the effects of various climates. In terms of maintenance and upkeep, it usually only requires occasional cleaning or lubrication of the operating mechanism. The vacuum circuit breaker pole type adopts a solid insulation structure and integrated solid-sealed poles, achieving maintenance-free. The installation form of the vacuum circuit breaker in the switch cabinet can be either fixed or withdrawable, and can also be installed on the frame. Main structure of circuit breaker ●The conductive circuit of the main part of the ordinary circuit breaker is set in a cylindrical insulating cylinder made of insulating material. This structure protects the vacuum interrupter from external environmental influences and mechanical damage. The circuit breaker main body is installed at the rear of the bracket-shaped circuit breaker operating mechanism housing. Depending on the conditions of the use site, a dust cover can be installed on the insulating cylinder as an additional device. This design helps prevent flashover and serves as additional protection against contamination inside the circuit breaker. In actual use, it is not necessary to remove it when the rated current and below are running, but it must be removed when the rated current and above are running. ●Pole-type circuit breaker poles are designed in a cylindrical shape and are installed at the rear of the bracket-shaped operating mechanism housing. The conductive part of the breaker pole is enclosed in an epoxy sleeve to protect it from impact and external environmental influences. The structure of the circuit breaker operating mechanism is a spring energy storage operating mechanism, and one operating mechanism operates a three-phase vacuum arc extinguishing chamber. The operating mechanism mainly includes two tension spring closing energy storage devices that transmit force to the connecting plate arm of each phase arc extinguishing chamber and an opening tripping device. In addition, there are also devices such as energy storage motors in front of the frame. Release device auxiliary switch control equipment opening and closing button manual energy storage shaft energy storage status indicator board closing and opening indicator board and other components. The operating mechanism is suitable for automatic reclosing operations, and since the energy storage time of the motor is very short, it can also perform multiple reclosing operations. The operating mechanism spring has two energy storage methods: manual energy storage and electric motor energy storage. The release locking electromagnet and the auxiliary switch energy storage status indicator drive the auxiliary switch. When the spring energy storage is completed, the motor circuit is cut off at the same time. When the spring system does not fully store energy, the closing release can be electrically blocked, and Provides a readiness signal for electrical operation.
