1. Product overview
"Ring network cabinet" is a collective term for load switchgear and combination electrical cabinet applied to ring network supply units. The ring network cabinet has the advantages of non-oil, non-toxic, non-burning fire and explosion hazard, and is equipped with manual and electric operating mechanisms at the same time, which provides the prerequisites for automatic control and remote control. HXGN type indoor high voltage vacuum load switchgear (ring network cabinet) is a three-phase AC indoor high voltage power distribution equipment.
It is suitable for indoor AC high voltage complete sets with rated voltage 3.6-12kV and rated frequency of 50Hz. It conforms to the national standard GB3906-91 "3-35kV indoor AC metal-enclosed switchgear", KL404/T "Indoor AC high-voltage switchgear ordering technical conditions" and the International Working Committee IEC-298 "AC metal-enclosed switchgear and control equipment" standard.
2. Product use
It is suitable for
10kV ring network power supply unit and terminal power supply unit for accepting, controlling and distributing electric energy, especially suitable for the protection of distribution transformers, so it is widely used in urban power grids, industrial and mining enterprises, residential areas, high-rise buildings, schools, parks and other places of power distribution systems.
3. Environmental conditions of product use
(1) Altitude: not more than 1000m;
(2) Ambient temperature: -25°C~+40°C;
(3) Surrounding relative humidity: daily average is not more than 95%, monthly average is not more than 90%;
(4) The surrounding air should be free from obvious pollution such as corrosive or flammable gases, water vapor, etc., without regular violent vibration;
(5) Earthquake intensity: 8 degrees.
When the conditions of use are different or there are special requirements, it is necessary to negotiate with the manufacturer.

1. It adopts advanced rotary compressed gas arc extinguishing technology, and the arc extinguishing ability is stronger. The air box is made of 3mm thick stainless steel material welded by advanced laser technology, and the product structure has high strength, good air tightness and beautiful appearance.
2. Unique visual window design, convenient for the state observation of load switch, making the operation more safe and reliable.
3. The product design fast grounding switch to ensure that the equipment can be safely and reliably grounded.
4. 90% of the materials used are metal materials, and when the service life of the product expires, it can be recycled without causing damage to the environment.
5. In order to meet the requirements of different user installations, two expansion methods are designed: side expansion (side expansion) and top expansion (top expansion).
6. With a convenient combination scheme, not only products with common box modules, but also products with single modules, the combination is more convenient and flexible.
7. Load switch, load switch-fuse combination electrical appliance, circuit breaker functional unit module width is consistent, small size, convenient for installation in space-constrained places.
