Original product description
GN19-12, 12C series indoor high-voltage disconnect switches (hereinafter referred to as disconnect switches) are indoor devices with a rated voltage of 12kV, three-phase AC 60. Hz, and are used for dividing and closing circuits when there is voltage and no load.
This series of isolation switch is three-pole type, consisting of base frame, rotating shaft, and lever, porcelain pillar insulator, gate knife and connection board.
The rotating shaft is placed on the base frame, on which three pairs of levers are welded, and the levers are necked with the gate knife through the pull rod porcelain insulator. The shaft extends out of the bottom frame, and any section of it can be connected with the operating mechanism.
Structure and working principle The conductive part of GN19-12/400, 630, 1000, 1250 type disconnect switch is fixed on the base by two pillar insulators for each phase.
(GN19-12C/400, 630, 1000, 1250 type has one pillar insulator and one porcelain casing insulator.) The three phases are installed in parallel, and the conductive part consists of static . Each phase of the , tie insulator and installed on the base of the spindle connected.
The spindle is connected to the connecting rod (user-provided) and CS6-1 type of moving mechanism through the handle. The connecting , which not only increases the heat dissipation area of the , but also improves the mechanical strength of the , so that the dynamic stability of the switch is improved. One end of the .
GN19-12/1000, 1250 in , plus the purpose of the magnetic locking plate is that when a large short-circuit current to enhance the two groove . GN19-12/400, 630 disconnect switches have a small limit through current, so there is no need to add a magnetic locking plate. Model meaning Use environmental conditions 1.
The upper limit of ambient temperature +40ºC, the lower limit -l0ºC, Note: Allow storage and transportation at -25ºC 2. Altitude not more than 1000m 3. Relative humidity: daily
