● Main features of the Zn63-12 Type Side-Mounted Indoor High Voltage Vacuum Interrupter

◆ Structural design

▶Side-mounted installation: Side-Mounted Indoor High Voltage Vacuum Interrupter usually fixed on the side wall of the switchgear, saving space, suitable for compact indoor switchgear (such as KYN28A-12 central cabinet).

▶Modular design: The vacuum interrupter, operating mechanism and insulation parts are modular, which is convenient for maintenance.

◆Arc extinguishing technology ：side-mounted Indoor High Voltage Vacuum Interrupter adopts vacuum interrupter , which has strong breaking ability, long service life and no pollution, and is suitable for frequent operation (such as capacitor bank switching).

◆Operating mechanism Spring energy storage mechanism: It can be operated manually or electrically (standard electric, manual), and the energy storage indication is clear. The mechanical life can reach more than 10,000 times, and the electrical life is about 10,000~20,000 times (depending on the load type).

◆Safety and protection：Side-Mounted Indoor High Voltage Vacuum Interrupter has excellent insulation performance, in line with IP2X protection level, to prevent foreign bodies from invading. Have anti-misoperation interlocking devices (such as opening and closing locking and grounding switch interlocking).

●Typical application scenarios of Side-Mounted Indoor High Voltage Vacuum Interrupter 

▶Substation: incoming and outgoing line protection of 12kV distribution system.

▶Industrial power consumption: motor protection in metallurgy, chemical industry and other fields.

▶New energy: high-voltage side switch of photovoltaic and wind power box transformer.

▶Frequent operation occasions: such as switching capacitor banks (special models need to be selected).
