**Brand: ROCKWILL** >132kV transmission substations, solar/wind farm booster stations, urban power grid, projects requiring bay-side voltage measurement without separate outdoor PT.
With the development of the power industry, the miniaturization of power equipment is the trend of future development and also the urgent need of current power users. Miniaturized electrical equipment can not only save and and civil engineering costs, etc., but also reduce the use of greenhouse gas SF6, meeting the requirements of the environmental protection situation. Combining years of high-voltage electrical design experience and absorbing the world's most advanced technical design concepts, our company has developed the latest generation of gasinsulated metal composite combined electrical appliance (HGIS). This combined electrical appliance has a compact structure and is particularly suitable for urban and mountainous substations. It is also the best choice for the renovation of old substations. In addition, this product is also very suitable for 40.5kV digital substations and can be used as digital electrical equipment.
RHP-145+PT is ROCKWILL segregated-tank hybrid gas insulated switchgear (HGIS) rated at 145kV, complying with IEC 62271-203, IEC 62271-100, IEC 61869 and KEMA type tested. It adopts self-blast SF6 circuit breaker with bistable spring or spring-hydraulic operating mechanism. Available rated current:2000A,2500A,3150A; rated short-circuit breaking current:31.5kA,40kA,50kA. Differing from standard RHP-145, this version integrates PT (voltage transformer) inside the SF6 tank alongside CB, DS, ES and CT, while main busbar uses air insulation. It provides integrated voltage & current signals for metering, protection and synchronism check. Widely used in 132kV transmission substations, renewable energy booster stations and urban power grid projects requiring bay voltage measurement
Hybrid gas insulated switchgear for 40.5kV to 245kV, combining compact GIS design with conventional component flexibility for reliable HV protection.
Hybrid gas-insulated switchgear (HGIS) for 126kV and 145kV, offering compact, reliable, and flexible high-voltage protection solutions.
Hybrid gas insulated switchgear (HGIS) for 145kV and 170kV systems, delivering compact, reliable protection with flexible configuration.
Il est entièrement conforme aux normes internationales de la CEI. Il adopte une conception optimisée du champ électrique avec une décharge partielle ≤3pC, un mécanisme à ressort normalisé à longue durée de vie (6000 cycles) et un système complet de verrouillage mécanique à cinq préventions pour éliminer les risques de mauvaise manœuvre. Le taux de fuite annuel de SF6 est ≤0,5 %, garantissant un fonctionnement stable et sûr du réseau.
