Description
Technical field
The present invention relates to the apparatus fields of current conversion station/substation of 220kV and above more specifically to relate to
And 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 1kV or more
Switch, often referred to simply as disconnecting switch is most commonly used a kind of electric appliance in high-voltage switch electric appliance, the operation principle of itself and
It is relatively simple for structure, but it is big due to the use of amount, and functional reliability requires high, design, foundation and safety to electric substation, power plant
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 operates again after can only first being disconnected circuit 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.
Currently, the development in two stages has been undergone in power industry about the design concept of GIS device isolation switch：
First stage：Traditional GIS disconnecting links design is usually using isolation switch and grounding switch as two independent work(
Energy unit, still has many mainstream producers to use this design at present, is charged in switch operation in order to avoid isolation switch closes a floodgate
Grounding switch is accidentally closed under state and the electrification under grounding switch combined floodgate ground state is avoided to close isolation switch, can only be used electrical
Interlocking is controlled, if electrical interlocks partial failure or misunderstanding lock, may cause power network line trip accident.
Second stage：Three station isolation switch design.The characteristics of design integration isolation switch and grounding switch and work(
Can, have three kinds of operating positions：1, the closing position that isolation switch main fracture is connected；2, the separated isolation of isolation switch main fracture
Position；The earthing position that 3 grounding switchs close a floodgate.Three station isolation switch are on the basis that traditional GIS disconnecting link electrical interlocks controls
On, introduce mechanical chain control function, form dual chain control, be equivalent to dual fail-safe, greatly reduce due to electrical or
Person's mechanical chain fails and the power grid accident probability of back brake maloperation occurs.Three station isolation switch realize mode be：Disconnecting link
Only one moving contact, and the both ends of moving contact are isolation fracture end and ground terminal respectively, therefore the work of moving contact at any time
Make position all and be unique or closes a floodgate through-flow with isolation fracture end or close a floodgate ground connection or neither through-flow with ground terminal
It is earth-free, the possibility of maloperation is substantially eliminated on disconnecting link contact machine performance.
Invention content
The first object of the present invention is to provide a kind of four station isolation switch, and there are two isolation fractures for tool.
