Overview
BKHB-12 series of environmental protection gas-insulated switchgear is a complete power distribution system for 12kV, three-phase AC 50Hz, with single busbar and single busbar sectioning systems. This product features simple structure, flexible operation, reliable interlocking, and easy installation, providing technical solutions for various applications and users. The adoption of sensor technology and information technology, combined with technical performance and flexible configuration options, can meet the ever-changing market demands and is suitable for intelligent grid requirements.
The BKHB-12 Eco-friendly Gas Insulated Ring Main Unit series is suitable for industrial and civil cable ring and distribution terminal projects. It is especially designed for power acceptance and distribution, and is ideal for use in urban residential areas, small secondary substation, switchgear, electrical branch boxes, box-type substations, industrial and mining enterprises, shopping malls, airports, subways, sports stadiums, railways, tunnels, and other locations.
The BKHB-12 Eco-friendly Insulated Ring Main Unit series features integrated modules for its switches and main electrical components.
The conductive parts are encapsulated with solid insulation, and the external wiring uses shielded cable connectors. The functional unit connections use shielded insulated busbars. Consequently, safety is significantly enhanced, with the operating mechanism employing a spring mechanism, boasting a mechanical lifespan of over 10,000 cycles. All operating data and equipment conditions can be remotely monitored, allowing for unattended operation. It truly is an excellent distribution device.
You may select the following units to compose an economical and practical power supply unit inside the cabinet: Vacuum New Circuit Breaker Unit [630A, 20-25kA]; Vacuum Negative Cat Switch Unit [630, 20-25kA].
Product Features
Environmental Protection: Products are manufactured using N2 or dry air as insulation medium, reducing greenhouse gas emissions, achieving environmental protection goals. Materials can be recycled domestically after their lifespan, determining the environmental friendliness of the product.
Wide Application Range: Non-toxic gas-free, ensuring environmental safety. Suitable for various environments including basements, tunnels, ships, and both indoor and outdoor settings. The high-pressure chamber can be filled with dry air or nitrogen, accommodating harsh conditions such as high altitudes, strong sandstorms, low temperatures, extreme cold, high environmental protection requirements, frequent operation areas, explosion-proof safety zones, high salt fog, and condensation conditions. Fully insulated and enclosed, it is suitable for equipment that has been temporarily submerged in water, which can continue operation after some cleaning and drying measures are taken.
Maintenance-Free: The BKHB-12 eco-friendly gas insulated switchgear series features fully enclosed operation mechanism and high-voltage switch sections, eliminating the need for cleaning and maintenance, thus reducing operational and maintenance costs. The switchgear is highly automated, with real-time online monitoring functions that notify users of equipment status. This is also conducive to the automation of the power distribution network, reducing manual operation costs and lowering production costs for power companies.
High safety: A comprehensive interlocking system, with clear visibility of three-phase isolation break points, prevents accidental operation accidents. The application of SF6 gas has been eliminated. Enhanced inter-phase isolation structure avoids inter-phase or multi-circuit short circuits that could expand or trigger explosion accidents. A vacuum chamber with explosion-proof and environmentally friendly gas is used, providing further protective properties for the switch with solid-sealed pole pieces.
·Ease of Operation: The disconnecting switch and grounding switch have a single operating handle, eliminating the need for identification and concern of errors. During the operation of the circuit breaker, the operating handle of both the disconnecting switch and grounding switch cannot be manipulated, thus simplifying the operation significantly and preventing operational mistakes.
The solidified pole piece is formed using the APG epoxy resin process, offering excellent electrical and mechanical properties. The solidified pole piece is a critical component of switches, serving both as an insulator and a load-bearing part. It meets technical requirements such as heat resistance, cold resistance, crack resistance, high mechanical strength, and good insulation strength.
·Single cabinet structure, utilizing general insulating busbars and cable connectors produced by professional cable accessories manufacturers. The switchgear can be assembled on-site, allowing for flexible expansion and avoiding the inconvenience of transporting and installing multiple combined cabinets. Of course, combined cabinets can also be provided upon request.
· Clearly visible, authentic isolation breakage
·Unified design across the entire product line, offering a variety of cabinet types (circuit breakers, load switches, PTs, busbars, busbars junctions, etc.) with identical geometric dimensions.
·The switch cabinets are equipped with intelligent interface and sensor installation positions, allowing for the integration of intelligent devices to meet the requirements of smart grids.
·The main busbar utilizes standard silicone rubber dry busbars.
·The disconnect switch is equipped with a three-position disconnect switch, installed on the busbar side.
· Replace SF6 load disconnect switch ring main cabinet.
