/b_[]
1. Overview
Type 3 indoor high-voltage vacuum circuit breaker is a three-phase AC indoor high-voltage switchgear with a rated voltage of .kV. The circuit breaker complies with my country's national standards "AC High Voltage Circuit Breaker", - "3. Indoor AC High Voltage Vacuum Circuit Breaker", - "Indoor High Voltage Vacuum Circuit Breaker Ordering Technical Conditions" and related standards, and has a reliable interlocking function , can carry out frequent operations, and has the ability of multiple openings and rapid reclosing.
The 3-type indoor high-voltage vacuum circuit breaker is designed with a front and rear split structure. The operating mechanism and arc extinguishing chamber are arranged front and back, and the main conductive circuit part is a three-phase floor-standing structure. The operating mechanism is a flat cloth spring operating mechanism with manual energy storage and electric energy storage. The operating mechanism is placed in the chassis in front of the arc extinguishing chamber. The chassis is divided into five assembly spaces by four middle partitions, in which the operating mechanism is installed. The energy storage part, transmission part, tripping part and buffer of the actuating mechanism
3 The circuit breaker can be used as a fixed installation unit and used in fixed switch cabinets. When used as a fixed type, it can be installed in two ways: front installation and side installation
3 The circuit breaker can also be used with a chassis truck as a separate handcart, mainly used in mid-mounted switch cabinets.
