1. Product Overview

The HXGN-12 SF6 fully insulated switchgear is an advanced switchgear designed specifically for medium-voltage power distribution systems. It comprises functional units and a sealed gas tank, including load switches, load switch-fuse combinations, and disconnectors-circuit breakers. Its unique design and superior performance play a vital role in medium-voltage power distribution.

2. Product structure characteristics

(1) Fully insulated design The switchgear seals all high-voltage live parts, such as load switches, grounding switches, busbars, etc., in a stainless steel box filled with low-pressure SF6 gas.

This fully insulated design offers multiple advantages:

1. High security:This prevents operators from direct contact with high-voltage live parts, significantly reducing the risk of electric shock and ensuring personnel safety. It also reduces the impact of external environmental factors (such as dust, moisture, and small animals) on high-voltage live parts, improving equipment reliability.

2. High protection level:The stainless steel box has good protective performance and can effectively resist harsh natural environment and human damage, extending the service life of the equipment.

(II) Arc Extinguishing Medium: SF6 is used as the arc extinguishing medium. SF6 gas has excellent insulation and arc extinguishing properties, extinguishing arcs in a short time, reducing arc damage to equipment and improving the breaking capacity and service life of switchgear. Compared with traditional arc extinguishing media, SF6 gas extinguishes arcs faster and more effectively, effectively ensuring the safe operation of equipment.

(3) The operating mechanism adopts an electric or manual energy storage spring operating mechanism. This operating mechanism has the following characteristics:

1. Flexible Operation: Users can choose between electric or manual operation to meet diverse needs. Manual operation ensures normal operation during power outages or emergencies. 2. High Reliability: The spring-operated mechanism offers advantages such as simple structure, reliable operation, and easy maintenance, ensuring stable operation of the switchgear.

(IV) Busbar Extension: The busbar can be extended in either direction, left or right, using busbar connectors. This design provides the switchgear with significant flexibility and scalability. Users can easily increase or decrease the number of switchgear units based on actual power distribution needs, implementing diverse power distribution solutions. Furthermore, the busbar connectors provide a reliable connection method that ensures the electrical and mechanical performance of the busbar.

3. Product Features

(1) Modular design The switchgear has a modular structure, and each functional unit is an independent module. This design has the following advantages:

1. Easy installation:The modular design makes the installation of the switch cabinet simpler and faster, reducing installation time and cost. It also facilitates on-site commissioning and maintenance.

2. Flexible combination:Users can arbitrarily arrange the functional units according to different design schemes to complete different power distribution tasks. This flexibility enables the switchgear to adapt to various complex power distribution requirements.

(II) Applicable to medium-voltage power distribution systems This switchgear is suitable for medium-voltage power distribution systems and can meet various power distribution requirements of medium-voltage power grids. It can be widely used in urban power grids, industrial enterprises, commercial centers, residential communities and other places, providing users with safe, reliable and efficient power distribution solutions.

4. Product Application Scenarios

In urban power grids, HXGN-12 SF6 fully insulated switchgear can be used in substation incoming and outgoing line switchgear, ring main units, and other equipment to distribute and control electrical energy. Its fully insulated design and high reliability adapt to the complex operating environment of urban power grids, ensuring the safety of electricity use for urban residents.

(2) Industrial Enterprises: In industrial enterprises, this switchgear can be used in factory power distribution rooms, workshop power distribution boxes, etc., to provide a stable power supply for industrial production. Its modular design and scalability can meet the ever-evolving power needs of industrial enterprises.

In commercial centers and residential areas, HXGN-12 SF6 fully insulated switchgear can be used in switchgear cabinets in distribution rooms, providing reliable power for commercial activities and residents' lives. Its safety and aesthetics complement the environment of commercial centers and residential areas.

5. Product technical parameters

(1) Rated voltage 12kV

(2) Rated current: Depending on the model and configuration, the rated current is generally between 630A and 1250A.

(3) The rated short-circuit breaking current is generally 20kA - 25kA.

(4) The SF6 gas pressure is generally 0.02MPa - 0.04MPa.

6. Product maintenance and care

(1) Regular Inspections Switchgear should be inspected regularly, including appearance inspection, electrical performance inspection, mechanical performance inspection, etc. Inspection contents include whether the box is damaged or deformed, whether the connections are loose, and whether the SF6 gas pressure is normal.

(II) SF6 Gas Testing: Regularly test the water content and purity of SF6 gas to ensure that the performance of SF6 gas meets the requirements. If the water content or purity of SF6 gas does not meet the requirements, it should be handled promptly.

(III) Maintenance of the operating mechanism: Maintain the operating mechanism regularly, including cleaning, lubrication, adjustment, etc. Check whether the operating mechanism is flexible and reliable, and whether the spring is fatigued or deformed.

(IV) Busbar Inspection Regularly check the busbar connections for looseness, heat generation, and insulation performance. If any problems are found, address them promptly.

The HXGN-12 SF6 fully insulated switchgear, with its fully insulated design, excellent arc-extinguishing performance, flexible operating mechanism, and scalability, is an ideal choice for medium-voltage power distribution systems. It provides users with safe, reliable, and efficient power distribution solutions and is widely used in various fields. Users should also ensure regular maintenance and care during use to ensure proper operation and longevity.
