3 Visible open/closed status
3.1 lt is easy to see the main contact position indicator which is color-coded just standing on the ground (Green-off;red -closed).The ind icator is directly connected with the main contacts of the drive shaft assembly to ensure accurate display of contact states.
4 Quick operation
4.1 operating mechanism with spring energy to ensure a quick closing and opening operation (less than 100 milliseconds).
5 Can realize remote control
5.1 lt is equipped with electronic controller,fit for in situ operation as well as FTU interface console operation.
6 Rugged switch
6.1The switch is made of proven durable,corrosion-resistant materials (special used in warships 304L stainless steel platelwhich ensures that there is a very long service life (30 years),and can be implement a series of operations.It has the idealcharacteristics as a column equipment.
7 Standard
7.1 Each switch before leaving the factory has been filled with SF6 gas,sealed,and test according to IEC60265-1(1988),GB40.504-1990 standard.

5.1 switch and controller appearance(Model:PGS-12/24/40.5)
1 Control box with a thickness exceeding 1.5 mm stainless steel plate,and the installation folder to install on a concrete pole.
2 The controller can operate in place of Pole,-LSB,but also can realize the remote control.SF6 gas pressure of
3 controllers monitor the Pole,-LSB.
If gas pressure drops below a preset threshold (0.3-0.4kg/cm2G),then the red ground board SF6 lowpressure indicator will light,and electric and manual operation are locked.
4 Control box installed the following operations with display devices:
4.1 operating switch:closed;disconnect
4.2 Operation selection switch:local/remote
4.3 operating locking switch:lock/unlock
4.4 Charging the battery test terminals and test switch
4.5 lamp test switch
4.6 Control power switch (on/off)and fuse
4.7 Indicator
-Show Contact Status:Closed (red),disconnect(green)
-Show the gas pressure low lock
-Displays the switch operation lock (control box/box)
-Charge state of the components and rechargeable batteries
5 rechargeable battery and charging unit are as follows:
5.1 The control power supply with a rechargeable battery
-This is DC24V rechargeable power.A single charge can operate the switch for more than 500 times.Built-inrechargeable battery,able to maintain operation when AC power failure,more than 24 hours.
5.2 charge the battery and charging device Necessary-according to the ambient temperature automatic control battery charge current.It includesprotection circuitry to prevent overch arging or excessive discharge.
5.3 Charging the battery test terminals
-With test terminal can display charging status,and no-load to check the status of the battery voltage andcharging device.
