IE-15.6/24 kV 630A solid insulated ring main unit is a new generation of environmentally friendly composite insulated ring main unit independently developed by our company. It is a fully insulated and fully sealed power supply unit. All live parts and switches of the primary part are completely sealed in an epoxy plastic shell, and there is no SF6 gas in the shell. The entire switchgear is not affected by the external environment, ensuring operational reliability and personal safety, and is maintenance-free.
The solid-sealed pole molded by the APG process encapsulates the current-carrying conductors such as the vacuum arc extinguishing chamber and the upper and lower outlet seats into a whole. The isolating switch is installed in the cavity of the solid-sealed pole, so that the main insulation method between phases is solid insulation. Single-phase insulated busbar design avoids serious faults such as phase-to-phase and grounding. The scalable busbar design enables unlimited expansion of functional units.
The ring network cabinet has the characteristics of simple structure, flexible operation, reliable interlocking, and easy installation. It is suitable for 50Hz/60Hz, 15.6/24 kV power systems and is widely used in industrial and civil cable ring networks and distribution network terminal projects. For the purpose of receiving and distributing electric energy, it is especially suitable for power distribution in urban residential areas, small substations, switching stations, cable branch boxes, box-type substations, industrial and mining enterprises, shopping malls, airports, subways, wind power generation, hospitals, stadiums, railways , tunnels and other places.
Environmental Protection:
It is designed with environmentally friendly materials, does not use SF6 gas as arc extinguishing medium and insulation, and has no pollution to the environment. The primary circuit uses a minimal contact design to ensure low energy consumption during operation.
Maintenance Free:
The solid insulated indoor AC high-voltage vacuum switchgear is in a fully sealed state except for the operating mechanism. This eliminates the need for cleaning and maintenance and reduces operation and maintenance costs. The IP rating can reach IP65.
Safety:
Since the touchable parts are shielded, the occurrence of personal electric shock accidents is eliminated and the safety of use is improved. The perfect interlocking interlocking system, the three-phase isolation fracture is clearly visible, avoiding misoperation accidents. The application of SF6 gas is completely eliminated, which avoids explosion accidents caused by the decrease in insulation performance and arc extinguishing ability of SF6 ring main unit due to insufficient gas pressure. Strengthen the phase isolation structure to prevent phase or multi-circuit short circuits from expanding or causing explosion accidents. There is an obvious visual window for the isolation fracture in front of the cabinet. You can check the isolation closing position, isolation separation position, and grounding closing position. The three working positions are convenient for on-site staff to check and determine the position of the isolation knife, which is very safe.
Ease of Operation:
The isolating switch and grounding switch has only one operating handle, so there is no need to identify or worry about mistakes. When the circuit breaker is running, the operating handle of the isolating switch and grounding switch cannot be operated. The operating procedures are clear at a glance. Anyone with a little knowledge of electricians can operate them without order. Complex technical training. This makes operation extremely simple and eliminates operational errors.

The ring network unit should be installed in a well-ventilated place, operated and maintained from the front. The base of the ring network unit has foot mounting holes. Indoor cabinets can be installed away from the wall or against the wall. The installation location is as shown in the figure. The flatness of the track laid on the installation foundation shall not exceed 2mm per square meter. The base of the ring network unit must be fixed to the foundation. When installing outdoors, the foundation is required to be built on higher ground, and the distance from the surrounding wall or shelter should not be less than 1 meter to avoid hindering the opening of the door. The walls of the pit are made of cement and solid bricks, and the surface is treated with anti-seepage treatment. The pit wall and foundation platform shall be made of 1:2.5 cement mortar with a thickness of 20 mm, and the surface must be smooth. Concrete is made in accordance with GB232-82 "Construction and Acceptance Specifications for Electrical Installation Projects". After the cable installation is completed, the floor of the cable room should be sealed to prevent moisture from entering the trench. The connection of the ring network unit must be connected to the on-site grounding network. There is a ground mark at the ground point of the ring network unit.
The movement case is made of epoxy gel and all components inside are maintenance-free for the declared product life.
The isolation and grounding positions can be observed to provide safety guarantee for operation and cable construction.
The system loop is completely isolated from the atmosphere, and a special arc pressure relief channel is designed on the air box to ensure the safety of operators and equipment.
The mechanical part is located on the outside of the air box and behind the front panel. This makes operation and replacement easier. The surface of the mechanical parts has undergone anti-corrosion treatment. Its movable parts have been lubricated before leaving the factory, which can meet the use of the product life cycle. In extreme environments (dust, sand and dirt) inspection, maintenance and, in some cases, replacement may be necessary.
