Product details

PRODUCT DESCRIPTION:

The GJXGN15-12 solid insulated ring network switchgear is a new generation of miniaturized and modular electrical switchgear. Its main feature 

is that the main circuit adopts a three-phase longitudinal arrangement to combine the functions of three position isolating switches and vacuum 

circuit breakers together. The entire device has a compact structure, small size, and adopts fixed installation. It can be widely used in 3-12kV threephase AC 50Hz power systems, suitable for various types of box type substations and ring network distribution systems.

The three position isolation switch has three positions: closing, isolation, and grounding. It adopts a spring operated mechanism, and each 

position is reliably positioned with a clear isolation fracture.

The circuit breaker mechanism adopts a modular design, with fewer components, compact structure, low operating power, and more stable 

performance.

There is a complete mechanical interlock between the isolation switch mechanism and the vacuum switch mechanism to ensure safe and 

reliable operation.

PRODUCT CATEGORY:

According to the type of switch, it is divided into load switch with grounding assembly (referred to as C module), load switch without grounding 

assembly (referred to as CB module), circuit breaker with grounding assembly (referred to as V module), circuit breaker without grounding assembly 

(referred to as VB module), circuit breaker interconnection switch (referred to as VZ module), load switch+fuse combination switch assembly (referred 

to as F module), and isolation switch assembly (referred to as G module).

FUNCTIONS AND FEATURES:

environment protection

The materials used in product manufacturing are all non-toxic and harmless substances, and no toxic or harmful substances are emitted during use. 

The materials can be recycled and reused after their life cycle, which determines the environmental friendliness of their use.

Fully insulated, fully sealed, and fully shielded epoxy resin switch housing and fuse housing (epoxy resin has excellent electrical, mechanical, and 

thermal properties, and has been used in electrical equipment for a long time, achieving good performance. The switch housing and fuse housing are 

formed using epoxy resin APG technology. The insulation housing is a key component of solid insulated switches, which is both an insulation part and 

a load-bearing part. It is required to meet technical requirements such as heat resistance, weather resistance, cracking resistance, high mechanical 

strength, and good insulation strength. The housing has a large volume, many embedded parts, and various shapes, making it difficult to manufacture. 

Our company has many years of experience in designing and manufacturing insulation parts, and strives to ensure high-quality mass production of 

this component from cylinder design, material formula, and process flow. According to the user's requirements, Requirement: Can provide a cylinder 

with external shielding grounding that can be touched

Maintenance free:

The solid insulation indoor AC high-voltage vacuum switchgear is in a fully sealed state except for the operating mechanism, which can avoid cleaning 

and maintenance and reduce the cost of operation and maintenance.

Security:

Due to the use of shielding measures on touchable parts, the occurrence of personal electric shock accidents has been eliminated, improving safety 

and usability. A complete interlocking system, with clear and visible three-phase isolation fractures, avoids the occurrence of misoperation accidents. 

The application of SF6 gas has been completely eliminated, avoiding explosion accidents caused by insufficient gas pressure leading to a decrease in 

insulation performance and arc extinguishing ability of SF6 ring main units. Strengthen the inter phase isolation structure to prevent the expansion or 

triggering of explosion accidents due to inter phase or multi circuit short circuits. Adopting a vacuum arc extinguishing chamber with explosion-proof 

performance, the switch sleeve provides further protection for the switch. The auxiliary grounding switch of the load switch fuse combination device is 

sealed in the fuse barrel with a vacuum switch tube.

Operability:

The isolation switch and grounding switch only have one operating handle, so there is no need to identify or worry about errors. When the circuit 

breaker is running, the operating handle of the isolation switch and grounding switch cannot be operated, and the operating procedure is clear at a 

glance. Anyone with a little knowledge of electricians can operate it, and complex technical training is carried out in a disorderly manner. This makes 

the operation exceptionally simple and prevents operational errors from occurring.

Intelligence:

The switchgear is equipped with intelligent interfaces and sensor installation positions, which can meet the requirements of the smart grid after 

configuring intelligent equipment.

Diverse operating mechanisms:

The switch can be equipped with two operating mechanisms: spring and permanent magnet, making it convenient for users to choose

APPLICATION FIELD:

Low temperature and cold regions: Without SF6 gas application, there is no need to consider the low-temperature operation of SF6 gas, and it can still 

operate normally at -45 ℃ .

Plateau region: There is no need to consider the impact of plateau atmospheric pressure on insulation performance.

Strong wind and sand areas: The safety protection level of the solid insulated ring main unit is IP67, and the control circuit room adopts special 

treatment to ensure long-term operation in strong wind and sand areas.

Coastal wet pool area: sealed with epoxy resin, resistant to moisture and salt spray corrosion, ensuring long-term use in coastal areas.

Areas with high environmental protection requirements: The impact of SF6 gas on atmospheric warming has been highly valued. Solid ring main units 

have eliminated SF6 gas, which has no pollution or harm to the environment and human life.

In the smart grid, due to the fact that both the main switch and the isolation switch can be electrically operated, the intelligent controller developed 

by our company can be selected to remotely control, telemetry, and communicate the switch equipment and substation site. It can achieve both 

decentralized control and convenient centralized control.
