High-Performance 12kv Circuit Breaker Indoor Sf6 Load Break Switch Disconnector¹

Product DescriptionProduct Description12kV Indoor SF6 Switch-Disconnector FL(R)N36 Load Break Switch LBS is a double-break rotary load switch using SF6 gas as the insulating and arc-extinguishing medium. It is suitable for 12kV power distribution systems. Each switch is permanently sealed after being filled with 0.4bar pressure SF6 gas. The switch can be installed vertically or horizontally. The typical installation method in the ring main unit is to install a steel partition horizontally between the cable room and the busbar room. This installation method isolates the busbar from the cable joint to comply with safety requirements for operation and maintenance. Combining the FLN36-12 indoor high-voltage SF6 load switch with other electrical components can realize control and protection functions and serve as the control and protection of electrical equipment in industrial and mining enterprises, civil power supply and secondary substations. Among them, the FLRN36-12kV load switch-fuse combination appliance matches the protection characteristics of the transformer and is especially suitable for ring network power supply units.12kV Indoor SF6 Switch-Disconnector FL(R)N36 Load Break Switch LBS is a double-break rotary load switch using SF6 gas as the insulating and arc-extinguishing medium.

The FLN36-12D load switch equipped with a single spring operating mechanism is mainly used for the incoming and outgoing line control unit. The FLRN36-12D load switch-fuse combination appliance equipped with a double spring operating mechanism is mainly used for transformer protection units.   Usage Environment1. Ambient air temperature: upper limit +40℃, lower limit -15℃.2. Environmental humidity: The daily average relative humidity is not greater than 95%, and the monthly average relative humidity is not greater than 90%.3. Altitude: The maximum altitude of the equipment installation site is 2000m.4. Earthquake: The earthquake intensity does not exceed 8 degrees.5. The surrounding air should not be significantly polluted by corrosive flammable gases, water vapor, etc. There should be no frequent severe vibrations.Rated voltageKVFLN36-12: 12; FLRN36-12: 12Rated frequencyHz50/60Rated currentA630, 1250Auxiliary circuit 1 min power frequencyV2000Rated thermal stability current / duration (3s/2s)?

In order to extinguish the arc quickly, when the switch is breaking the current, an arc will be generated when the moving and static contacts are just separated. At this time, due to the magnetic field of the permanent magnet, the arc will be driven to move quickly, causing the arc to It is elongated and continuously combined with SF6 gas to be quickly dissociated and cooled. It is extinguished when the current crosses zero. The double fracture opening distance has the insulation level of isolating the fracture. Permanent magnet rotating arc principle, small operating power, strong extinguishing ability, light contact burn, and extended electrical life.Installation and Commissioning1. Before installation and debugging, be sure to read the instruction manual carefully and make the following preparations: First, check whether there is any damage to the appearance. Damaged products should be stopped immediately. The second step is to remove contamination on the surface of the product due to transportation or other reasons.2. When the operating mechanism and the switch body are assembled, it must be ensured that they are reliably fixed, and their connecting parts should be reliably fixed on the operating shaft of the switch body, and the components connecting the load switch should also be reliably fixed on the switch body. on the switch.3. After the installation is completed, confirm that the load switch is in the opening position, insert the operating handle into the grounding operating hole on the upper end of the panel, and turn the handle 180 clockwise. To perform ground closing, rotate the handle 180 degrees counterclockwise. Complete the closing of the grounding switch.4. When performing the closing operation, first confirm that the load switch is in the opening position, then insert the operating handle into the load switch operating hole at the lower end of the panel, and rotate the operating handle 180" clockwise to complete the closing operation of the load switch.5. During the process of moving the load switch from the closing position to the opening position, use the K-type operating mechanism, insert the operating handle into the operating hole of the load switch, and rotate the handle counterclockwise 180" to perform the opening operation; for the A-type operating mechanism, Operating mechanism, press the opening button to open the load switch, check through the observation window whether the position of the switch is correct, and whether the corresponding observation instructions meet the requirements.6. Note: The grounding or load can only be closed when the switch is in the open position!Maintenance and CareUnder normal use conditions where the environment meets the requirements of the installation and operation instructions, the switch body is guaranteed to be maintenance-free for 20 years. Due to environmental differences, necessary inspection and maintenance work on the load switch is still required.1. According to the working environment, conduct appropriate visual inspection of the insulation cover between June and December, and remove dirty and damp surfaces.2. Carry out lubrication and operation inspection of the operating mechanism 1 to 2 times a year to ensure normal operation.3. For load switches equipped with pressure gauges, the readings of the pressure gauges should be checked from time to time.4. When a fault current passes through the load switch fuse combination appliance and one phase fuse blows, all three phase fuses must be replaced. When replacing, the grounding switch must be closed first before replacement, and ensure that all three-phase fuses are installed in place. Main ProductsCompany ProfileXiamen Insulation Electrical Technology Co., Ltd. was established in 2013.
