10KV combined overvoltage protector, high-voltage three-phase three column cabinet lightning arrester TBP-B-12.7F/131
Three-phase combined overvoltage protector (three-phase combined arrester) is used to protect power equipment insulation from overvoltage hazards. It is a new type of arrester that not only limits overvoltage between phase and ground but also effectively restricts overvoltage between phases, which ordinary arresters cannot achieve. It is widely used to protect vacuum switches, rotating motors, parallel compensation capacitors, power plants, substations, and more. This combined protector has been in operation for over a decade, and practical evidence shows that it is a feasible and effective measure to limit interphase overvoltage. One combined protector can perform the function of six ordinary arresters. Due to the use of large-capacity zinc oxide resistors as the main components inside the protector, it has excellent voltage-current characteristics and the ability to absorb overvoltage, providing reliable protection for equipment, and is highly favored by the power system.
