Features

1 SF6 gas-insulated

1.1 SF6 gas is a kind of nontoxic,nonflammable and electrical insulating gas.It has the excellent characteristic of arc extinction.

2 Drivepipe with large diversity

2.1 In addition to the standard ceramic drivepipe,we can also provide a variety of solutions,including rubber insulators usedin the epoxy resin filing equipment

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.

Structure

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.
