Product Introduction

CYGT solid fully insulated metal-enclosed switchgear is a kind of fully insulated, fully sealed, maintenance-free solid insulated vacuum switchgear. The high-voltage live parts are cast and molded with epoxy resin materials with excellent insulating properties, combining the vacuum interrupter, the dominant electric circuit and the insulating support organically as a whole, and the functional units are connected through the fully-insulated solid converging busbars. Therefore, the whole 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, 12kV power system, widely used in industrial and civil cable ring network and distribution network terminal project, as the acceptance and distribution of electric energy, especially suitable for urban residential distribution, small substations, open and close houses, cable branch box, box-type substation, industrial and mining enterprises,

Shopping malls, airports, subways, wind power generation, hospitals, stadiums, railroads, tunnels and other places.

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

Product Classification

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 contact switch (referred to as VZ module), load switch + fuse combination electrical switch assembly (referred to as F module), disconnector assembly (referred to as G module).

Functions and Features

◇ Eco-friendly

The materials used in the manufacture of the product are all non-toxic and harmless substances, and no toxic and harmful substances will be discharged during use.

Fully insulated, fully sealed, fully shielded, epoxy resin switch barrel, fuse barrel ( Epoxy resin has excellent electrical, mechanical, and thermal properties, and has been used in electrical equipment for a long time, and has achieved good results. The switch barrel and fuse barrel are molded by epoxy resin APG process. The insulating cylinder is the key component of the solid insulated switch, which is both an insulator and a load-bearing part. It is required to meet the technical requirements of heat resistance, weather resistance, crack resistance, high mechanical strength and good dielectric strength at the same time. The cylinder is large in size, with many inserts and different shapes, so it is difficult to manufacture. The company has many years of experience in designing and manufacturing insulating parts, and has made great efforts to ensure the excellent mass production of the parts from the cylinder design, material formulation, and process flow. According to the user's requirements, the outer shield can be provided with a ground that can be touched)

◇ Maintenance-free:

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

◇ Safety:

Due to the shielding measures used in the touchable parts, the occurrence of personal electric shock accidents is eliminated and the safety of use is improved. Perfect interlocking and interlocking system, three-phase isolation fracture is clearly visible, which avoids the occurrence of misoperation accidents. The application of SF6 gas is eliminated, and the explosion accident caused by the reduction of insulation performance and arc extinguishing ability of SF6 ring main unit due to insufficient gas pressure is avoided. Strengthen the interphase isolation structure to avoid the expansion or explosion accident caused by the short circuit of the phase or multi-circuit. A vacuum interrupter with explosion-proof performance is adopted, and the switch sleeve has further protection performance for the switch. Load switch - the auxiliary grounding switch of the fuse combination appliance is sealed in the fuse barrel by vacuum switch tube.

◇ Ease of operation:

There is only one operating handle for the disconnector grounding switch, no need to identify and worry about mistakes, when the circuit breaker is running, the operating handle of the disconnector and the grounding switch can not be operated, the operating procedures are clear at a glance, as long as the personnel with a little electrical knowledge will operate, and the complex technical training will be carried out in disorder. This makes operation extremely easy and eliminates the occurrence of operating errors.

◇ Intelligent:

The switch cabinet has intelligent interfaces and sensor installation positions, and can meet the requirements of smart grids after being equipped with intelligent equipment.

◇ Variety of operating mechanisms:

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