Summarize

XGN-12 series solid insulated closed ring network switchgear is a kind of solid insulated vacuum switchgear with full insulation, full seal and free maintenance. The high-voltage live parts are cast with epoxy resin material with excellent insulation performance, and the vacuum arc extinguishing chamber, the main electric circuit, and the insulation support are organically combined into a whole. The functional units are connected by fully insulated solid bus bars. Therefore, the entire switchgear is not affected by the external environment, which can ensure the reliability of equipment operation and the safety of operators.

The ring network cabinet has the characteristics of simple structure, flexible operation, reliable interlocking, easy installation, etc. It is suitable for 50Hz,12 kV power system, and is widely used in industrial and civil cable ring network and distribution network terminal projects, as the acceptance and distribution of electric energy. It is especially suitable for power distribution in urban residential areas, small substations, opening and closing stations, cable branch boxes, box-type substations, industrial and mining enterprises, shopping malls, airports, subways, wind power generation, stadiums, railways, tunnels and other places.

Because the product has the advantages of full insulation, full sealing and full shielding, it is especially suitable for use in areas with harsh environment such as high altitude, high temperature, hot and humid, cold and serious pollution.

Function and Characteristics

Environmental Protection:

The materials selected in the manufacturing of the product are all non-toxic and harmless substances, and any toxic and harmful substances will not be discharged in use, and the materials can be recycled after the life cycle, which determines the environmental protection of the use.

Fully insulated fully sealed fully shielded epoxy resin switch Simple entity, fuse Simple entity(Epoxy resin has excellent electrical properties, mechanical properties, thermal characteristics, very early used in electrical equipment, has achieved good results. The switch  Simple entity and fuse Simple entity are formed by epoxy resin APG process. The insulation Simple entity is a key component of the solid insulated switch, which is both an insulating part and a bearing part. It also meets the technical requirements of heat resistance, weather resistance, cracking resistance, high mechanical strength, good insulation strength and so on.  Simple entity volume is huge, many inserts, different shapes, manufacturing is a certain difficulty. The company has many years of experience in the design and manufacture of insulation parts, from the Simple entity design, material formula, process to ensure the high-quality mass production of the parts. According to user requirements, can be provided with external shield ground can be touched Simple entity)

Maintenance Free:

In addition to the operating mechanism, the high-voltage switch part of the solid insulated indoor AC high-voltage vacuum switch cabinet is in a fully sealed state, so that it can be free from cleaning and maintenance, reducing the cost of operation and maintenance.

Security:

Due to the use of shielding measures in the touchable parts, the occurrence of personal electric shock accidents is eliminated, and the safety of use is improved. Perfect interlock system, three phase isolation fracture is clearly visible, to avoid the occurrence of misoperation accidents. The application of SF6 gas is completely cancelled, and the explosion accident caused by the decrease of insulation performance and arc extinguishing ability of SF6 ring network cabinet due to insufficient gas pressure is avoided. Strengthen the interphase isolation structure to avoid expansion or explosion caused by short circuit between phases or multiple circuits. The vacuum arc extinguishing chamber with explosion-proof performance is adopted, and the switch sleeve has further protection performance for the switch. The auxiliary grounding switch of the load switch-fuse combination appliance is fixed in the fuse case with a vacuum switch tube.

Easy to Operate:

The isolation switch grounding switch has only one operating handle, no need to identify and worry about mistakes, when the circuit breaker is running, the isolation switch grounding switch operating handle can not be operated ,The operation procedure is clear at a glance, as long as a little electrical knowledge of the personnel will operate, did not need complex technical training. This makes the operation extremely simple and prevents the occurrence of operation errors.

Intelligent:

The switch cabinet has intelligent interfaces and sensor installation positions, and intelligent equipment can meet the requirements of smart grid.

Multiple Operating Mechanisms:

Switch can be equipped with spring, permanent magnet in two operating mechanisms, convenient for users to choose.

Main Technical Parameter

Switch can be equipped with spring, permanent magnet in two operating mechanisms, convenient for users to choose.

Application

◇ Low temperature cold area: no SF6 gas application, no need to consider SF6 gas low temperature operation problem, can also operate normally under -45℃.

◇ Plateau area: there is no need to consider the effect of plateau atmospheric pressure on insulation performance.

◇ Strong sand area: solid insulated ring network cabinet body safety protection level IP67, control loop room adopts special treatment to ensure long-term operation in strong sand area.

◇ Coastal wet pool area: epoxy resin seal, anti-moisture, anti-salt spray corrosion, to ensure long-term use in coastal areas.

◇ Areas with high environmental protection requirements: The impact of SF6 gas on atmospheric warming has been highly considered, and the solid ring network cabinet has canceled SF6 gas, without any pollution and harm to the environment and the person.

◇ Smart grid: Because the main switch and the isolation switch can be electric, the intelligent controller developed by the company is selected, which can carry out remote control, telemetry and remote communication on the switchgear and substation site, which can carry out decentralized control and convenient centralized control.
