Disconnecting switch can reliably pass through rated current and short-circuit current under gate-dividing state.It is with following work( Energy:The circuit of the circuit and electrification of reliable Ground Split maintenance or segmentation;Opening-closing bus switching current;Can divide, exciting current very The no-load current of small transformer, the little unloaded bus-charging current of the electromagnetism current voltage and length of voltage transformer.
Earthing switch is a kind of grounding apparatus artificially manufactured, makes coupled major loop that can be abutted against under "on" position Ground.Its is with the following functions:When earthing switch closes a floodgate, make coupled major loop reliable ground.Suit circuit electrostatic induction Electric current and em induced current.Close fault current (peak value closes).Core equipments of the DS/ES as GIS, its own point, Conjunction action is to provide kinetic energy by operating mechanism, and switching on and off operation is carried out by transmitting maincenter.Operating mechanism with/ground connection is isolated The kind of drive for switching (DS/ES) is to ensure isolating/grounding switch (DS/ES) function and performance important link.
Product in ahead market is mostly an operating mechanism while being switched for each phase in switching mechanism(Generally three Phase)Action drives are provided, and connection type is driven using the connecting rod of indirect drive mostly, and such mode is complicated, work( Rate loss is larger, very high to manufacturing and designing requirement.
Invention content
The object of the present invention is to provide a kind of operating mechanism direct connection structures of switchgear, to solve to use in the prior art Problem complicated existing for connecting rod indirect drive, power loss is big.
In the present invention the technical solution adopted is that:The operating mechanism direct connection structure of switchgear, including switching mechanism and behaviour Make mechanism, each mutually switch of the switching mechanism is correspondingly provided with respective operating mechanism respectively, and each mutually switch is equipped with input shaft, Each operating mechanism is equipped with output shaft, and the operating mechanism direct connection structure further includes the direct connection being fixedly connected with switchgear Transmission device, the direct-connection transmission device include transmission device ontology and are rotatably arranged on the intrinsic direct-connection transmission of transmission device Axis, the input shaft and output shaft are sequentially connected by the direct-connection transmission axis.
On the transmission device ontology switch fixed structure and operation machine are respectively equipped in the both ends of direct-connection transmission axis axial direction Structure fixed structure, the switching mechanism, operating mechanism and direct-connection transmission device pass through the switch fixed structure and operating mechanism Fixed structure is fixed together.
The switch fixed structure and operating mechanism fixed structure are flange arrangement.
The direct-connection transmission axis is arranged by bearing in the axis hole on transmission device ontology, the shaft hole inner wall and direct connection Grooved seal circle is equipped between transmission shaft.
The direct-connection transmission axis is used to set in axis hole described in one end retraction of the input axis connection and on the end end face There is the drive connection hole that simultaneously rotation stop cooperation is inserted into for input shaft.
The switching mechanism is disconnecting switch, earthing switch, high speed grounding switch or three-station isolating grounding switch.
The present invention uses above-mentioned technical proposal, each mutually switch of switching mechanism to be correspondingly provided with respective operating mechanism respectively, And it is driven and is connected by the direct-connection transmission axis of direct-connection transmission device between the output shaft of operating mechanism and each mutually input shaft of switch It connects, transmission path is simple, and direct-connection transmission axis is not in big energy loss, and power loss is small, and reliable transmission can ensure open The global reliability and stability of equipment are closed, and is coupled easy to maintain.
