The rotary blade type isolating switch GN30-12 indoor high-voltage rotary isolating switch is an indoor high-voltage electrical equipment adopting a rotary blade structure, which realizes circuit opening and closing operations through the rotation of the blade. This product adopts a three-phase common underframe structure, with two sets of insulators and contacts arranged on the upper and lower planes, with a rated voltage of 12kV, an AC frequency of 50Hz, and a rated current ranging from 400A to 1250A. It can be matched with CS6-2 type, JSXGN-10 type manual or electric operating mechanisms, and is suitable for circuit opening and closing operations under no-load conditions. It can be installed in combination with high-voltage switchgear or operate independently.
This equipment adopts a compact design, and has installation methods such as flush-mounted type, wall-passing type and corresponding grounded type, supporting double grounding of moving and static contacts. The product complies with GB1985-89 standard, and has technical parameters such as thermal stable current of 12.5kA-31.5kA and dynamic stable current of 31.5kA-80kA. The environmental adaptation conditions include altitude ≤1000m, temperature -10℃ to +40℃, daily average relative humidity ≤95%, and it is suitable for indoor places without severe vibration and chemical corrosion. The GN30-12D derivative model adds a grounding knife structure, further expanding application scenario requirements.
The GN30 indoor high-voltage rotary isolating switch is a new type of rotary blade type isolating switch. Its main structure is to fix two sets of insulators and contacts on the upper and lower planes of the three-phase common underframe, and realize the opening and closing of the switch through the rotating blade. This switch adopts the JSXGN-12 type interlockable operating mechanism for transmission, and all insulating parts adopt porcelain insulators with large creepage distance. The contacts adopt sheet-type contact fingers and linear contact, which reduces operating force and increases rotation flexibility. The GN30 indoor high-voltage rotary isolating switch has a relatively compact structural design, small floor area, certain insulation capability, and relatively simple installation and adjustment processes. It is suitable for indoor power systems with rated voltage of 12kV (can also be used in 10kV systems) and AC frequency of 50Hz and below. It is used for closing circuits with voltage and no load, and can be used in combination with high-voltage switchgear or used alone. Its models include GN30-12/400-12.5, GN30-12D/400-12.5, GN30-12/630-20, GN30-12D/630-20 and other series. This isolating switch is commonly used in box-type metal-enclosed fixed switchgear, helping to realize the compact design of the switchgear structure. The rated voltage of the GN30-12 indoor high-voltage rotary isolating switch is 12kV, the AC frequency is 50Hz, and the rated current covers the range of 400A, 630A, 1000A, 1250A, 2000A and 3150A. The thermal stable current includes 12.5kA, 20kA, 31.5kA and 40kA, and the dynamic stable current is 31.5kA to 80kA, with different parameters corresponding to different models.
