Product Overview

HB -12 type environmental protection gas insulated ring network cabinet is 12KV, three-phase AC 50HZ, single bus and single bus sectional system of complete sets of distribution devices. The product has the characteristics of simple structure, flexible operation, reliable interlocking and easy installation. It can provide satisfactory technical solutions for different applications and different users. With the adoption of sensing technology and information technology, with advanced technical performance and simple and flexible configuration, it can meet the changing demand of the market and can be applied to the intelligent requirements of the power grid.

The environmental protection gas insulated ring network cabinet is suitable for industrial and civilian cable ring network and distribution terminal project. As the use of electrical energy, it is especially suitable for urban residential area distribution, small two substation, open and closed station, cable branch box, box type substation, industrial and mining enterprise, shopping mall, airport, subway, wind power generation, hospital, stadium, railway, tunnel and other places.

The RETH -12 environmental gas insulated ring network cabinet meets the relevant national standards, electric power industry standards, international standards and other standards. The switch and the main electrical components are integrated modules, the interphase conductive parts are solid insulation package, the outside connection adopts the shielded cable joint, and the function unit connects the busbar to the fly down insulated bus. Therefore, the use of safety greatly improved, the operating mechanism using spring machinery, mechanical life of more than 10000 times. All its running data and equipment status can be monitored and monitored remotely and unattended. It is a power distribution device with excellent performance.

The following units can be used in the cabinet to form an economical and practical power supply unit.

Zhao air circuit breaker unit (630A, 20-25ka)

Vacuum load switch unit (630, 20-25KA)

Environmental protection:

All the materials used in product manufacture are innocuous and harmless material, using N2 or dry air as insulation medium, reducing greenhouse effect gas emission, achieving environmental protection purposes, and using no toxic and harmful substances in use. The material can be recycled after the life cycle, which determines the environmental protection of the use.

The scope of application is wide:

The safety of the environment is determined by not using any toxic and harmful gases. Dry air and nitrogen can be filled in the basement, the tunnel, the ship, and the various environment inside and outside the house, and the high pressure storehouse can be filled in. It can adapt to the bad conditions, such as high altitude, strong wind sand, low temperature, cold, high environmental protection, frequent operation places, safety and explosion-proof places, high salt fog and condensation conditions. . Human insulation is totally enclosed, suitable for short time flood inundation, and can be continued after some cleaning measures are adopted.

High security:

The perfect interlocking interlocking system, the three-phase isolation fracture is clear and visible, avoids the occurrence of misoperation accidents, cancels the application of SF6 gas, strengthens the interphase isolation structure, avoids the interphase or multi circuit short circuit and enlarging the explosion accident. A vacuum interrupter with explosion-proof performance is adopted, and the sealing pole has better protection performance.

Ease of operation:

The isolation switch earthing switch has only one operating handle, without identification and worry. When the circuit breaker runs, the operation handle of the isolated switch grounding switch can not be operated, without the need of complex technical training. This makes the operation very simple and the village is absolutely wrong.

The solid sealing pole is molded by epoxy resin APG technology. It has excellent electrical and mechanical properties. The solid seal pole is the key part of the switch. It is both the insulation and the bearing parts, and it meets the heat resistance. Cold resistant, anti cracking, high mechanical strength, good insulation strength and other technical requirements.

The single cabinet structure adopts universal insulated busbars and cable plug heads produced by professional cable accessories manufacturers. The switch can be assembled on site and expanded at will, avoiding the inconvenience of transportation and installation caused by multiple combination cabinets. Of course, user requirements can also provide a combination cabinet.

Clear visible isolation fracture

The whole series of products are designed to provide a variety of cabinet types (circuit breakers, load switches, PT, bus, parent and so on), and the geometric dimensions are completely consistent.

The switch cabinet has intelligent interface and sensor installation position, and can meet the requirements of smart grid after the configuration of intelligent equipment.

Standard main line using standard silicon rubber dry busbar

The isolation switch adopts three station isolating switch installed on the bus side.
