Abstract
The invention provides a stepping three-station switch comprising an operating mechanism. The operating mechanism is connected with a propelling device in a dynamic sealing unit; the propelling device is connected with a moving contact; and static contacts and the moving contact are arranged coaxially. Three static contacts are arranged linearly n a front-middle-rear mode. The operating mechanism has a gear-wheel driving structure and is formed by a driving gear wheel and a driven gear wheel, wherein the two gear wheels are engaged mutually. The propelling device is an insulating lead screw. On the basis of dynamic sealing, the operation power generated by the operating mechanism is converted into the kinetic energy of the propelling device; and thus the moving contact is driven to make linear motion back and forth and is connected with the corresponding static contact, so that the function of closing, isolation, or grounding can be realized. According to the invention, the switch has a simple structure; a few parts are used; the manufacturing and usage become convenient; the needed materials are reduced; the processing cost is low; the assembling becomes convenient; the switch is easy to control; and the performances are reliable.
Description
Technical field
The present invention relates to a kind of stepping three-station, belong to power transmission and distribution technical field.
Background technology
Gas-insulated switchgear three-station has " combined floodgate ", " isolation ", " ground connection " three kinds of functions and position, is promoted screw mandrel rectilinear direction to advance by stepping operating mechanism, is retreated, it is achieved each position function.
Specifically, three stations refer to three operating positions: 1, the closing position that isolated switch main fracture is connected, 2, main fracture isolated location separately, 3, the earthing position of ground side.Three-station incorporates the function of isolation switch and earthed switch in fact exactly, the stationary contact position being led directly to Guan Bi isolation fracture or ground connection fracture by a moving contact is completed, thus can realize mechanical latching, prevent major loop charged conjunction ground cutter, because moving contact a position, and can only switch unlike traditional isolation, operator is operator, ground cutter is ground cutter, it is possible to there is maloperation between two cuttves.And tri-station isolating switch is a moving contact, the operating position of moving contact is at a time unique, be not at closing position, it is simply that at isolated location or earthing position, it is to avoid the probability of maloperation.
The existing three-station based on chopper switch has a disadvantage in that switch contact structure is complicated, consumes fine copper more, and material and processing cost are higher, and assemble cumbersome.
Summary of the invention
The technical problem to be solved in the present invention is the structure how simplifying three-station, optimizes the designing technique of uniform electric field, reduces consumables cost, improves processing and the convenience installed.
In order to solve above-mentioned technical problem, the technical scheme is that a kind of stepping three-station of offer, it is characterised in that: including operating mechanism, operating mechanism connects propulsion plant by movable sealing, and propulsion plant connects moving contact, and static contact and moving contact are coaxially disposed;
Static contact has three, according to before, during and after position word order.
Preferably, described operating mechanism is gear transmission structure, is made up of intermeshing master gear and driven gear.
Preferably, described master gear and driven gear gear ratio are 1: 1.
Preferably, described propulsion plant is insulation screw mandrel.
Preferably, described operating mechanism and movable sealing, movable sealing and propulsion plant adopt four square hole shaft linkages.
Preferably, described static contact is fixed on pedestal.
Preferably, in described static contact, forward and backward position contact is " one " type, and middle position contact is T-shape, keeps fixed range between each static contact.
Preferably, described static contact is for being with built-in fingertip ring contact, and described moving contact is ring contact.
Preferably, the operating work that operating mechanism produces is converted into the kinetic energy of propulsion plant by described movable sealing, drives moving contact to realize fore-and-aft direction rectilinear motion, connects with corresponding static contact.
Preferably, by described master gear rotating, link driven gear transmission, and then drive moving contact stepping to advance or retreat, and connects with corresponding static contact, it is achieved " combined floodgate ", " isolation " or " ground connection " function.
Compared to existing technology, stepping three-station provided by the invention has the advantages that
1, simple in construction, number of parts is few, manufactures and easy to use;
2, material requested is little, and processing cost is low;
3, assembling and easy to maintenance;
4, switch is stepping, it is easy to control, dependable performance.
