Fln36-12D High Voltage Sf6 Indoor Load Break Switch Disconnector Breaker

PRODUCT DETAILS Sulfur hexafluoride load switchDescription:*FLN36-12D, FLRN36-12D sulfur hexafluoride load switch, load switch-fuse combination, and loadable cable head load switch are designed and developed by our company by absorbing foreign advanced technology and combining with the operating requirements of our country.*After comprehensive type test, the product conforms to GB3804 "3~ 63kV AC high voltage load switch", GB16926 "high voltage load switch-fuse combination", IEC60265, IEC60420 standard requirements.*The product has three positions of arc extinguishing chamber, which is reliable in interlocking , high insulation strength at breakage, large climbing distance design, and the outlet end is protected by voltage sharing protective cover.* Install cable head type load switch, the outlet end of which is equipped with touch-type cable front connector, the inlet and outlet line is installed with high-voltage cable, and it is equipped with cable branch (connection) box.* The switch has a special dynamic seal and fixed seal design, reliable seal, and is equipped with pressure gauge in obvious position. It is a new generation of high voltage switchgear equipped with urban power grid for operation monitoring to ensure operation safety.* This product is suitable for three-phase AC 10KV, 50HZ power systems, industrial and mining enterprises, high-rise buildings, residential areas, pre-installed substation places, used to open and close the load current, fault current, control and protection lines and distribution transformers.1) Easy to install the fin36-12 SF6 load switch and assembly apparatus are made into a unique unit type (the upper part of the cabinet).and are installed in a stacked way, which greatly reduces the difficulty of the cabinet. Complete set of drawings for the supporting cabinet can be provided2) Three-position switch has three positions: closing, opening, and grounding3) There is an observation window on the end face to observe the state of main contact and grounding contact4) Direct-acting pneumatic arc extinguishing mode5) The sealing shell is filled with SF6 gas as insulation and arc extinguishing medium.6) The switch has gas filling nozzle, safety relief valve, and SF6 gas pressure gauge.7) Manual and electric operation can be selected.8) It is resistant to the harsh environment and has passed condensation and pollution type tests9) You can choose the shunt line diagram or over-current release (optional at the same time 10) Optional moisture switch, 1 on 1 off-4 on 4 off11) Interlocking between cabinets is optional12) Pluggable live indication device on the operation panel is optional 13) It conforms to GB3804 and GB16926 national standards TECHNICAL PARAMETER  The technical parameters of the form are for reference only. Customized products can consult online customer service!  The name of theunitsdataFLN36-12DFLRN36-12DThe rated voltage 12 12 Rated frequency 50 50 Rated currentA630 125 Load switch rated short - term tolerance current/rated short - circuit durationkA/S20/3-Ground switch rated short-time tolerance current/rated short-circuit durationkA/S20/2-Rated peak tolerance current and rated short-circuit closing currentkA50125 ( expect )rated breaking current Active load breaking currentA630 -Closed-loop breaking currentA630 -5% rated active load breaking currentA31.5 -Turn off the cable charging currentA10-Turn off the no-load transformer capacityKVA12501250Turn off the transfer currentA-1700Expected short circuit breaking currentkA-50Rated insulation level1minl frequency withstand voltage phase, to ground/offKV42/4842/48Lightning shock withstand voltage phase, to ground/offKV75/8575/85Mechanical life 500500SF6 rated air pressure (gauge pressure at 20°C)"MPa0.04-0.050.04-0.05THE USE OF CONDITIONSAmbient temperature: -15ºC~+40ºC;Altitude: no more than 1000m;Relative humidity: the average value of daily relative humidity shall not exceed 95%, the average value of monthly relativehumidity shall not exceed 90%, the average value of daily water vapor pressure shall not exceed 2.2kPa, and the average value of monthly water vapor pressure shall not exceed More than 1.8 kPa;Ambient air: not visibly contaminated by dust, smoke, corrosive and/or flammable gases, vapors or salt spray; The vibration or ground movement from the outside of the switchgear and control equipment can be ignored;The amplitude of electromagnetic interference induced in the secondary system shall not exceed 1.6kV.Special Service Conditions: According to the national standard GBT11022-999 "Common Technical Requirements of High Voltage Switchgear and Control Equipment Standard", the circuit breaker should be operated under normal service conditions. If the working conditions used by the user are different from the normal operating conditions, such as the installation site is over 1000m above sea level, the ambient air temperature exceeds the limit specified in the normal operating conditions or the high humidity whe
