Factory-direct KYN28 12kV Armored Removable Switchgear wholesale – 50% off bulk orders.KYN28 Removable Switchgear has a complete "five-prevention" interlock function, namely preventing incorrect tripping or closing of the circuit breaker, preventing pushing in or pulling out of the circuit breaker drawer while the load is on, preventing closing of the grounding switch while energized, preventing power supply when the grounding switch is closed, and preventing entering energized compartments by mistake. This ensures the safety of operators and equipment. It can be equipped with various and multiple brand drawer-type vacuum circuit breaker products, such as VS1 type and VD4 type, making the application more extensive. KYN28 12kV Armored Removable Switchgear can be configured with customized sensors, cameras and other intelligent devices to achieve product intelligence. Through the intelligent monitoring module, remote control, data collection and fault diagnosis can be realized. The key parts such as the circuit breaker chamber and the cable chamber are designed reasonably, facilitating installation, maintenance and component replacement. The drawer can be pulled out for maintenance without large-scale power outages.
KYN28 12kV Armored Removable Switchgear has the "five prevention" interlocking functions of preventing incorrect operation of circuit breakers, pulling and pushing the handcart while carrying load, closing the grounding switch while energized, supplying power when the grounding switch is in the closed position, and entering energized intervals by mistake. Through mechanical and electrical dual interlocking, it ensures operational safety. Each compartment (busbar compartment, circuit breaker compartment, cable compartment) has an independent pressure release channel, which limits the spread of arcs during internal faults and protects equipment and personnel safety. The enclosure protection grade reaches IP4X, and the compartments and circuit breaker compartment doors are IP2X when opened, effectively preventing foreign object intrusion and electric shock risks.
The circuit breaker handcart adopts a central-mounted design. Handcars of the same model can be interchanged, and during maintenance, there is no need to replace the cabinet, shortening the power outage time. Various domestic and imported vacuum circuit breakers such as VS1, VD4, VH1 can be configured to meet the needs of different users. It supports overhead incoming and outgoing lines, cable incoming and outgoing lines, and left-right interconnections, adapting to single busbar, single busbar sectioning or double busbar systems.
The cabinet of KYN28 12kV Armored Removable Switchgear is assembled from galvanized aluminum sheet by CNC processing. The structure is compact, occupying a small area, and can be installed against the wall to save space. All operations and maintenance are completed in front of the cabinet, without the need for lateral or rear operations, adapting to narrow spaces. Heating devices can be installed in the circuit breaker compartment and cable compartment to prevent condensation, and the lighting device is convenient for night maintenance.
The applicable environmental temperature is -10℃ to +40℃, and the special design can extend to -25℃ to +45℃. The daily average relative humidity is ≤95%, and the monthly average is ≤90%, adapting to humid environments. It meets the requirements of an 8-level seismic intensity, suitable for areas with frequent earthquakes.
KYN28 12kV Armored Removable Switchgear can be equipped with microcomputer protection devices, intelligent instruments, wireless temperature measurement systems, etc., to achieve remote measurement, remote control, and remote signaling functions, improving operation and maintenance efficiency. It supports condition monitoring and fault warning, assisting in the construction of smart grids.
