The Usune JN15 series Indoor Earthing Switch is a professional safety protection device designed specifically for medium-voltage power distribution scenarios. Manufactured by a professional high-voltage circuit breaker factory in China, it strictly adheres to domestic and international electrical industry standards, ensuring stable and reliable overall performance.
Ang produktong ito ay angkop para sa 12kV, 24kV, at 36kV AC 50/60Hz indoor power distribution system. Ito ay ganap na katugma sa medium-voltage switchgear gaya ng KYN28, KYN61, at ring main units, at ito ay isang pangunahing bahagi ng metal-enclosed switchgear. Pangunahing ginagamit ang device para sa circuit grounding at safety isolation sa panahon ng operasyon at pagpapanatili ng power system, ganap na naglalabas ng natitirang boltahe, inaalis ang panganib ng electric shock at pagkasira ng kagamitan, at komprehensibong pagprotekta sa personal na kaligtasan ng mga tauhan ng maintenance at ang ligtas na operasyon ng power equipment.
The Indoor Earthing Switch has extremely high adaptability, widely covering mainstream indoor medium-voltage power distribution scenarios such as urban and rural power grid substations, industrial and mining substations, and power distribution systems for new energy power plants. It is currently the most widely used safety grounding protection device in the medium-voltage power field.
Adopting a simple and rational integrated mechanical structure, the opening and closing actions are flexible, requiring minimal operating force, and the operation is smooth and without jamming, effectively reducing operational difficulty and the probability of human error.
The entire unit boasts high mechanical strength, excellent dynamic and thermal stability, and can withstand instantaneous short-circuit impact currents under complex operating conditions. Its long-term structural stability meets the continuous operation requirements of power systems.
The Indoor Earthing Switch features a compact and rationally laid-out structure, easily adapting to various mainstream indoor high-voltage switchgear such as KYN28 and KYN61. Installation is convenient, and its versatility is strong, significantly improving equipment assembly flexibility.
Equipped with a professional mechanical interlocking device, it effectively avoids misoperation during operation and maintenance, preventing safety accidents caused by violations and improving the safety level of equipment operation and maintenance.
Utilizing high-quality conductive and insulating materials, it boasts outstanding conductivity and insulation properties, is corrosion-resistant and anti-aging, and can operate stably for extended periods under various indoor conditions, resulting in a longer service life.
Isang 12kV urban power grid substation renovation project sa Jiangsu Province ang nagpatibay ng Usune JN15-12 Indoor Earthing Switch na ipinares sa KYN28 switchgear sa buong linya, na responsable para sa safety grounding isolation work ng araw-araw na operasyon at pagpapanatili at pana-panahong inspeksyon ng mga kagamitan sa substation. Ang kagamitan ay gumagana nang matatag sa loob ng tatlong taon mula nang i-commissioning ito. Pagkatapos ng bawat pagkawala ng kuryente, ang natitirang boltahe ay ganap na nailalabas, na nakakamit ng mga zero operational error at zero na mga panganib sa kaligtasan, na epektibong nagpapabuti sa kaligtasan at kahusayan ng pagpapatakbo at pagpapanatili ng substation.
A1: This product series covers 12kV, 24kV, and 36kV voltage levels, adaptable to 50/60Hz AC medium-voltage power distribution systems, and perfectly compatible with mainstream indoor metal-enclosed switchgear such as KYN28, KYN61, and various ring main units. It boasts strong versatility and can meet the matching needs of most indoor medium-voltage switchgear.
A2: The core function of the product is safe grounding and isolation protection. During the maintenance and commissioning of high-voltage equipment, it can reliably ground the circuit, quickly and thoroughly release residual voltage from equipment and lines, isolate energized parts of the system, eliminate safety hazards such as electric shock and equipment damage, and comprehensively protect the safety of maintenance personnel and power equipment.
A3: Ang usune JN15 series grounding switch ay nilagyan ng nakalaang mekanikal na interlocking device, na bumubuo ng kumpletong mekanismo ng interlocking na pangkaligtasan na may katugmang switchgear. Mabisa nitong pinipigilan ang mga hindi awtorisadong maling operasyon gaya ng pagsasara ng switch habang pinapagana o pinapagana nito ang grounded circuit, kaya naiiwasan ang mga aksidente sa kaligtasan. Samantala, ang produkto ay may mahusay na mga katangian ng pagkakabukod at katatagan ng istruktura, na maaaring matiyak ang pangmatagalang ligtas at maaasahang operasyon ng kagamitan.
