Kxsgn-12-SI53 solid insulated fully enclosed medium voltage switching equipment; The full range of schemes include circuit breaker protection, transformer protection, load control, fuse combination, PT power supply, busbar lifting, used transformer, etc., providing perfect series of solutions for the upgrading and transformation of power grid and distribution users, and allocating smart terminal base station combination to meet the needs of smart power grid. The product can be used as the power system ring network distribution equipment, also can be used as the urban construction of industrial and mining enterprises distribution equipment, with the characteristics of versatility.

Solid insulated fully enclosed switching equipment; Is to use solid insulation materials insulation medium, connect the vacuum arcing chamber and conductive, isolating switch, grounding switch, mistress lines, branch bus, main electric circuit of the single or group after encapsulated with solid dielectric coated to one or a few has a certain function, can be combined again or extension features full insulation, sealing performance module, all of them, and people can reach the module surface coated with conductive or half electric shielding layer and reliable grounding ring network cabinet directly.

The main circuit module, which can be touched by one person, is equipped with grounding net and coated with conductive shielding layer and directly and reliably grounded, so that there will be no risk when invalid maintenance is carried out and users are absolutely safe in operation and maintenance.

The circuit breaker, isolation switch and busbar are all connected by on-line monitoring technology, and the invention patent is obtained.

The new insulating material is the alloy synthesis process of new insulating material epoxy resin + rubber particle + silica spherical particle + silica strip particle + silicon micro powder with shielding net, and the invention patent is obtained.

The three-station isolation switch can be pressurized with 0.04mpa of dry air by sealed insulation box body to prevent the internal invasion of moisture and the production of condensation, and the pressure gauge is installed to monitor the internal pressure online to prevent leakage from causing infiltration of moist gas to produce internal condensation.

The medium pressure system is completely protected from the adverse environment (pollution, corrosive gases, condensation, moisture, dust, etc.).It significantly reduces the probability of arc occurrence, has a longer expected service life, and has the highest reliability under any circumstances.

· Solid insulation technology -- no SF6 gas insulation, no greenhouse gas, absolute environmental protection.

· Modular design -- circuit breaker, three-station isolation switch with grounding device, small size, compact structure, easy operation and maintenance.

· A comprehensive and perfect series of solutions and a combination of solutions are changeable, with two structures of upper and lower isolation to solve various user solutions.

· Extension modification -- various changes can be implemented in the field. The 375 width design is a direct replacement of the original SF6 product.
