Today, I'd like to introduceFully Insulated ring mesh cabinetsCommon models, HXGN15-12 and HXGN17-12.

HXGN15-12:HXGN15-12 Ring cabinet is a new generation of metal closed switchgear with six sulfur fluoride coincident switch, vacuum circuit breaker and vacuum load switch as the main switch. The cabinet adopts air insulation, which is suitable for distribution automation, small size and scalable. It has the characteristics of simple structure, flexible operation and reliable interlock.

HXGN17-12:HXGN17-12 box fixed metal closed switchgear is suitable for three-phase, AC 50 (60) Hz, rated operating voltage 3-12 kv, rated operating current 630A and below the complete set of systems for control, protection and monitoring. Especially suitable for frequent operation of the occasion, its bus system is a single-bus structure, distribution device. Mainly applicable to industrial and mining enterprises and institutions power distribution and power system box substation transceiver has "five anti-defense" locking function.

Now you can choose the type of ring cabinet according to the different characteristics of different models.

Typical solid insulated ring cabinet Energy electrical appliances is the early study of solid insulated ring cabinets enterprises. After years of efforts, has developed two kinds of products, corresponding to two categories: the first generation of solid cabinet main circuit for vacuum circuit breaker or vacuum load switch + vacuum insulation isolation/grounding switch, the second generation of solid cabinet main circuit for vacuum circuit breaker or vacuum cathode. Load switch + Air insulation isolation/grounding switch, visual fracture.

Advantages include: 1. Product and Environment harmony, main circuit solid insulation, isolation grounding three stations switch solid insulation or air insulation, cabinets do not use SF6 gas, do not produce temperature rise gas, do not destroy the ozone layer; 2. The use of high-performance epoxy resin materials can simplify the main circuit structure, to achieve miniaturization, lightweight; ; Operating mechanism design and product modularization design, small number of parts, gas pressure monitoring is eliminated during the life cycle, reduced maintenance, and even maintenance-free.

1. Technical features of the first generation of fixed cabinets

The main structure of the first generation power solid cabinet is the second generation product, that is, vacuum circuit breaker or vacuum load switch + vacuum insulation isolation/grounding switch structure.

12 generations of products are based on current sealing and vacuum insulation technology. The circuit breaker/load Switch vacuum arc extinguishing chamber and three-station vacuum arc extinguishing chamber were poured into epoxy resin material by epoxy resin (APG) process respectively. The single-phase switching unit is a circuit breaker/load switch connected to the three-station vacuum arc extinguishing chamber by a single conductive element. Finally, the insulated bus and other insulation connectors are assembled together to form a single-phase switching unit. Fully insulated, fully enclosed, anti-condensation solid insulated ring mesh switchgear. The sealing design of the solid state switch is a fully enclosed design of the whole pouring type, which can make the protection level of the solid-state switch reach IP67, so that the performance of the product is not affected by the change of the external environment. The structure of the switch is designed separately for each phase, so it has the ability to completely avoid interphase short circuits.

2. Technical features of second generation fixed cabinets

The second generation of medium energy power solid cabinet main structure for the first product, that is, vacuum circuit breaker or vacuum load switch + Air insulation isolation/grounding switch structure.

Compared with the first generation of solid cabinets, its structure is characterized by the use of coaxial knife gate rotating structure and observation window in the vacuum Arc extinguishing Chamber of the three-phase circuit breaker, and the pouring of solid insulating materials in the three-bit switch (isolated grounding) shell, which can be directly observed to make the power more safe and reliable.
