Description
Technical field
The apparatus field of current conversion station/transformer station of 220kV and above is the utility model is related to, more specifically
Say, be related to a kind of double-fracture disconnecting switch with ground connection linkage.
Background technology
Disconnecting switch (is commonly called as " disconnecting link "), generally referred to as high voltage isolator, i.e. isolation of the rated voltage in more than 1kV
Switch, often referred to simply as disconnecting switch is most commonly used a kind of electrical equipment in high-voltage switch electric appliance, the operation principle of itself and
It is relatively simple for structure, but because usage amount is big, functional reliability requires high, to electric substation, the design of power plant, foundation and safety
The influence of operation is larger.Disconnecting switch is mainly characterized by no arc extinguishing ability, can only divide in the case of no load current,
Close circuit.Disconnecting switch is used for each step voltage, and as changing circuit connection or making circuit or equipment and isolated from power, it is not disconnected
Stream ability, operated again after can only first circuit be disconnected with miscellaneous equipment.The general connection with maloperation when preventing from switching on-load
Locking device, it is sometimes desirable to which pin switchs to prevent from disconnecting under the magneticaction of big failure.
At present, the design concept in power industry on GIS device isolation switch has undergone the development in two stages：
