Kkg-Kyn28-12 Indoor AC Metal Enclosed Plug-in Switchgear

BRIEF DESCRIPTION OF THE SWITCHGEAR KYN28-12KV INDOOR AC METAL ENCLOSED PLUG-IN SWITCHGEAR -  is technically advanced, stable in performance, reasonably structured, convenient to use and safe and reliable power distribution equipment. It is especially suitable for controlling power generation, transmission, distribution and consumption equipment in AC 50Hz and 12kV power supply systems. FEATURES . Fully enclosed.   a) Metal enclosures and fully enclosed structures, low voltage chambers, and high voltage chambers are isolated from each other.    b) The busbars are insulated with heat-shrinkable materials and have extremely high insulation properties.   c) The fast grounding switch is used for grounding and has the ability to switch off short-circuit currents.   d) All equipment operations including the closing and opening of circuit breakers, the pushing in or pulling out of circuit breaker carriages, and the closing and         opening of grounding switches, etc., can be performed with the door panels closed.   e) It has a reliable interlock to effectively prevent misoperation.    f) Through the front and rear observation windows on the door panels, the closing and opening status of the circuit breakers, the position and energy storage           status of the carriages, the closing and opening position of the grounding switches, and the connection status of the cable heads can be easily observed.2. Highly practicala) The enclosure protection level is IP4X, which can prevent dirt and small animals from entering.b) The carriages are maintenance-free, and the associated operating mechanism requires little maintenance.c) The carriages have good interchangeability and the circuit breakers are very easy to replace. d) The secondary lines are laid in generously sized line slots, which are beautiful and easy to trace.3. Wide adaptabilitya) Applicable to incoming and outgoing lines such as cables and overhead busbars.b) Multiple parallel cables can be connected in parallel.In summary, the KYN28-12KV switchgear has an advanced fully enclosed structure, stable and practical performance, flexible adaptability and high reliability, making it an ideal power distribution equipment.  CONDITION OF USE The KYN28 indoor AC metal-enclosed plug-in switchgear can operate normally under certain special conditions such as vibration, corrosion, and high altitude after proper measures are taken. However, operating beyond the agreed conditions may affect the safe and reliable operation of the equipment, so the specific operating requirements must be clarified in the technical specifications.NORMAL OPERATING CONDITIONS-1. Environment temperature: Maximum temperature: +40°C, minimum temperature: -40°C, and the average value measured within 24 hours does not exceed 35°C. 2. Humidity conditions are as follows: the average relative humidity per day does not exceed 95%; the average monthly relative humidity does not exceed 90%; the average daily water vapor pressure does not exceed 2.2kPa; the average monthly water vapor pressure does not exceed 1.8kPa. Under these conditions, condensation may occasionally occur. 3. The altitude does not exceed 2000M. For special cases exceeding 2000M, it must be stated in advance. 4. The surrounding air is not significantly polluted by dust, smoke, corrosive and/or flammable gases, vapors, or salt fog.5. External vibrations or ground movements from the switchgear and control equipment can be ignored.6. The amplitude of electromagnetic interference induced in the secondary system does not exceed 1.6kVSPECIAL OPERATING CONDITIONS-1. When operating outside the normal environmental conditions specified in GB/T11022, the company, and the user can negotiate special operating conditions exceeding the normal operating conditions and reach an agreement. To prevent condensation, the switchgear is equipped with heaters, which should be put into use when the switchgear is in the standby state. The heaters should also be turned on when the switchgear is running normally.2. When installed in places with severe vibration (over 4m/s2) such as hydropower stations, reduction measures should be taken, such as vibration pads, vibration dampers, etc. The installation precautions should be indicated in the technical conditions. 3. For installation in severely corrosive environments such as chemical plants, the anti-corrosion level should be at least C4 or above, and it should be able to work normally in such an environment for 20-30 years. Anti-corrosion and insulation treatment should be performed on internal components. The detailed requirements should be indicated in the technical conditions.4. For installation in areas with seismic intensity above grade 8, shock absorption pads must be installed underneath to enhance the seismic capacity. The specific seismic design requirements should be clarified in the technical conditions. DESIGN & MANUFACTURE PROCESS Based on more than 30 years of design, manufacturing, and
