HXGN17-12
// Product Advantages
The main switch adopts a load switch with a static contact insulation cover or a load switch fuse combination electrical device. This ring main cabinet is divided into a busbar room, a switch room, and an instrument room, eliminating the need for phase partition boards and break plug boards, which can prevent are light short circuit accidents inside the cabinet and ensure the personal safety of personnel during maintenance and replacement of fuses.
The main switch can be selected as a combination of compressed air load switch or vacuum load switch and its fuse according to user requirements, while the external dimensions of the switchgear can be basically unchanged.
The selected FN12-12 type load switch has a gas-compression arc extinguishing structure. The rated number of breaking current operations is higher than 100 times, and its arc extinguishing performance is safe and reliable.
The mechanical lifespan of the vacuum load switch has reached 10000 times, with a long service life and excellent performance, making it a priority product for promotion in the power system.
The operating mechanism can be manual or electric, making it easy to achieve the three remote requirements of the power system.
Equipped with a comprehensive device to prevent electrical misoperation and meet the "five prevention" requirements.

// The following are the common application scenarios of the HXGN17-12 Air Ring Main Unit:
1. Upgrading and Transformation of Urban Distribution Networks
It is suitable for cable branching and ring network power supply in densely populated areas, such as urban main roads and underground power distribution rooms in commercial complexes. It solves the problem of space shortage during the capacity expansion of the distribution network and meets the requirements of high-reliability power supply of the "double ring network".
2. Intelligent Power Distribution in Industrial Parks
It meets the needs of industrial users for high reliability and flexible expansion. It is suitable for electronic factories, chemical industrial parks, and warehousing and logistics centers. It provides impact protection for equipment that starts and stops frequently and enables dynamic distribution of multi-circuit loads.
3. Power Distribution Systems in High-rise Buildings
It is suitable for the medium-voltage power distribution layers of office buildings and super high-rise residential buildings. It solves the problems of vertical busbar installation and fire protection requirements, ensures reliable wiring in narrow shaft spaces, and can withstand the current fluctuations when equipment such as elevators and air conditioners are started.
4. Scenarios of New Energy Access
It helps the grid connection of distributed energy sources such as photovoltaic power and wind power. It is suitable for the power distribution needs of charging stations and energy storage power stations, provides protection and control for bidirectional power flow, and can adapt to the voltage fluctuations of new energy power sources.
5. Power Grids in Rural and Remote Areas
It can cope with harsh outdoor environments and meet the simplified operation and maintenance needs of rural power grid transformation, mountainous area power transmission, and border guard posts. It is designed to be maintenance-free to deal with large temperature differences, high dust content, and high humidity.
// FAQ
Q: What is the main advantage of the HXGN17-12 air-insulated ring main unit compared to similar products?
A: This product adopts a combination of a vacuum load switch and a fuse. Its mechanical life reaches 10,000 cycles, and the short-circuit breaking capacity reaches 31.5 kA, which is far beyond the industry average level. At the same time, it supports modular expansion and the "three-remote" functions of power distribution automation, and can achieve automatic fault location (with an accuracy of 98%). The comprehensive performance is more reliable.
Q: Can the equipment adapt to the harsh environments of high humidity or coastal areas?
A: Absolutely. The cabinet frame is treated with color - zinc plating and the surface is sprayed with epoxy powder, passing the 1000 - hour salt - spray test. The protection level reaches IP4X (IP54 is optional). Combined with a silicone rubber insulating cover, it can effectively resist the erosion of moisture and salt spray.
Q: What is the maintenance cycle of the equipment? Does it require frequent inspection and maintenance?
A: The maintenance - free cycle of the core component, the vacuum interrupter, is as long as 20 years. The mechanical operating mechanism has passed the 2000 - cycle life test, and the mean time between failures (MTBF) exceeds 100,000 hours. In daily operation, it only needs to be remotely monitored through the power distribution automation system, which significantly reduces the operation and maintenance costs.
