Product Description
The high-voltage magnetic drive high-voltage vacuum circuit breaker is a key new generation switchgear that combines magnetic drive and vacuum arc extinguishing technology. Rated voltage - up to 12 kV, rated current - 630–1250 A, rated short circuit current - 20–80 kA. The external insulation is made of weather-resistant epoxy resin, does not contain oil and SF₆ gas, and is environmentally friendly. Estimated service life is more than 15 years. Supports local, remote (for some models - up to 50 m) control and integration with automated systems, adapted to various operating conditions.
Design Features
◆ Stable control: The magnetic drive contains a minimum number of parts, low power consumption when turned on, no risk of spring fatigue, and does not require regular maintenance. Synchronized switch-on and switch-off technology accurately suppresses switching overvoltages and inrush currents at switching on, which is especially important when switching sensitive loads.
◆ Long arc extinguishing life: in a vacuum arc extinguishing chamber, short arc burning time, rapid recovery of dielectric strength, minimal electrical wear of contacts. The resource for switching off the rated current is 30–50 cycles at full load and more than 5000 cycles at the rated current, which ensures a long electrical life.
◆ Intelligent Integration: Equipped with dual-core ARM9 + DSP architecture, integrating measurement, protection and communication functions. Supports wireless and wired data transmission, provides remote monitoring, fault warning and automatic restart, allowing integration into distribution network automation systems.
◆ Adaptation to operating conditions: does not contain environmentally hazardous substances. The design for outdoor installation is resistant to adverse weather conditions; The version for indoor installation is compatible with the main types of distribution cabinets. Suitable for use in power plants, metallurgy, transport and other industries.
◆ Emergency reliability: equipped with a mechanical manual drive that allows you to turn the switch on and off in the absence of power, which guarantees control in emergency situations.
