The FLN36-12 (LS2) indoor AC sulfur hexafluoride load switch is a three-phase AC 50Hz indoor device with a rated voltage of 12kV. The FLN36-12 (LS2) combination electrical appliance is composed of the FLN36-12 (LS2) indoor AC high-voltage SF6 load switch and indoor high-voltage current limiting fuse. After the impact of the fuse is activated, the load switch can automatically open. When the fault current is less than the minimum breaking current of the fuse, the load switch can operate normally to open again. This product can be used for the protection and control of electrical equipment in industrial and mining enterprises and substations.
This switch complies with the standard requirements of GB3804, GB16926, and IEC60420.

FLN36-12 indoor AC sulfur hexafluoride load switch model and meaning

Technical parameters of FLN36-12 indoor AC sulfur hexafluoride load switch
1. The technical parameters of the load switch are shown in Table 1

structural characteristics
This product uses SF6 as the arc extinguishing and insulation medium. The moving contacts of the switch are sealed in a reinforced epoxy resin sealed chamber, which is filled with SF6 gas at a pressure of 1.4 bar. Install two windows made of thermoplastic material on the switch housing for observation. Each switch undergoes strict sealing performance testing and related electrical performance testing before leaving the factory, ensuring maintenance free and reliable long-term operation.
Load switches can be easily combined with fuses to become load switch fuse combination electrical appliances.
The load switch can be operated manually or electrically. The operating mechanism can be a single spring or double spring operating mechanism. Equipped with a complete set of central interlocking devices at the front end of the institution. It can avoid misoperation and is suitable for multiple interlocking methods.
The FLN36-12 (LS2) load switch has the following three states:
-Close the switch
-Open the gate
-Grounding
