PGS-630A Pole Mounted Intelligent SF6 Load Break Switch

The sf6 load break switch is used for breaking rated voltage 12/24/40.5kV,rated current 630A、50/60Hz power distribution system, closing load current and over load current of power system,it could separate automatically track sections of power distribution which faults occur. This intelligen product load switch is matched with electroniccontroller which is with the latest technology.The switch has manual,motor,remote operation modes. The electronic controller would be installed inside the stainless steel box, so it could be used in various climate conditions. Besides that,the wire/wireless modem installed inside control box could achieve remote monitoring and controlling. If s easy and convenient for installation the switch on pole, and that could reduce the execution cost.

Standard application condition

Operation condition as follows:
Ambient temperature
Air temperature: max: +50°C, min. -40°C。
Relative humidity: 110%
Altitude 3000m
Wind pressure 700pa (equivalent to wind speed 34m/s)
Seismic intensity: 8 degree
Installation site: No fire disaster, explosion danger, chemical corrosion and frequent strenuous vibration places)

Characteristics
SF6 gas insulation
SF6 gas is nontoxic, incombustible, electrical insulating gas, it is with excellent arc extinguishing characteristic.
Bushing diversity
Expect standard porcelain bushing, could provide many schemes, include rubber insulator in epoxy device bushing.
Visible breaking/ closing status
It’s easy to see the indicator which marked with color in main contact position from earth, (green- breaking; red-closing). The indicator would connect directly with drive shaft of main contacts to make sure of showing contact status exactly.

Quick operation

Adopt spring energy storage type operation mechanism to make sure of quick opening and closing operation(less than 110ms)
Could achieve local or remote controlling Couldachievelocaloperationwithelectroniccontroller.andalsocouldachieve master control operation with FTU/RTU interface.
Durable switch
The switch is made of durable, anti-corrosion material (304L stainless steel)which is verified, that could make sure of long lifetime (30 years).And also could achieve series operation.

Standard

Every switch has been filled with SF6 gas and dealt with sealing treat merit before
sending out from factory. The test has been done according to IEC60265-1(1988).
GB3804-1990 standards.
