Description
Technical field
The utility model relates to a kind of SF6 totally enclosed type combined electric appliance equipment technical field, specifically a kind of three-phase transmission mechanism of 550kV isolating switch.
Background technology
Gas insulated metal enclosed swit chgear equipment can be divided into some functional units such as circuit breaker, current transformer, isolating switch, earthed switch, voltage transformer, lightning arrester, and isolating switch, earthed switch all are the bigger functional units of amount ratio wherein.Isolating switch is divided into angle type isolating switch and line style isolating switch at present, and earthed switch is divided into inspection earthing switch and high speed grounding switch.These several kinds isolation, earthed switches are widely used among the GIS.Arrange that because 550kVGIS is the three-phase branch mailbox isolation, earthed switch also are that the three-phase branch mailbox is arranged, and the three-phase arrangement at same interval is identical.Because need having quick short circuit, high speed grounding switch closes the ability of closing; In order to guarantee when the fault in time with line-to-ground; The high speed grounding switch of each phase all needs independent setting operation mechanism, and inspection earthing switch and isolating switch do not have such function, but all setting operation mechanism deciliter actions that come control switch respectively of the isolating switch of each phase, inspection earthing switch; This spline structure is with regard to more complicated, and cost can be than higher.Three-phase transmission mechanism in the past adopts column gear transmission, and it is bigger and heavy that whole mechanism seems.
Summary of the invention
The utility model provides a kind of simple in structure in order to overcome above-mentioned defective, reduces cost, and can realize the three-phase transmission mechanism of the three 550kV isolating switches that link.
The technical scheme that the utility model adopts is: a kind of three-phase transmission mechanism of 550kV isolating switch; Comprise motor-operating mechanism; Also comprise drive link and gear drive, described motor-operating mechanism has only one, and this motor-operating mechanism is provided with two mutual vertical and synchronous output shafts; An output shaft is connected with an isolated switch in limit, and another output shaft is connected with drive link; Distributed and arranged has two gear drives on drive link; The gear drive set inside has power transmission shaft; Power transmission shaft is connected with drive link; Power transmission shaft is provided with bevel gear, and this bevel gear is connected with the mechanism output shaft through another bevel gear, and the other end of mechanism's output shaft is connected with isolating switch.
Through the utility model three traditional motor-operating mechanisms being driven three-phase isolation switch respectively is improved to and drives three-phase isolation switch simultaneously by a motor-operating mechanism and carry out work; Motor-operating mechanism is provided with two output shafts in the utility model; An output shaft is connected with an isolated switch in limit; Another output shaft is connected with drive link, is provided with two gear drives on the drive link and is connected with other two isolated switches respectively, realizes that three of isolating switch link; Gear drive in the utility model has adopted two bevel gears to carry out engaged transmission, can change the transmission direction of power, makes three-phase isolation switch be positioned at the same side of drive link, and this structure is convenient to the layout of isolating switch.The utility model is realized three-phase isolation switch divide-shut brake and simplified structure simultaneously, we designed a kind of simple in structure and isolate reliably, earthed switch three-phase link gear.

Embodiment
Combine accompanying drawing that the utility model is further described at present; Fig. 1 is a kind of embodiment of the utility model; Comprise motor-operating mechanism 1, drive link 2 and gear drive 3, described motor-operating mechanism 1 has only one, and this motor-operating mechanism 1 is provided with two mutual vertical and synchronous output shafts; An output shaft is connected with an isolated switch in limit, and another output shaft is connected with drive link 2.Distributed and arranged has two gear drives 3 on drive link 2.Gear drive 3 set inside have power transmission shaft 4, and power transmission shaft 4 is connected with drive link 2, and power transmission shaft 4 is provided with bevel gear 5, and this bevel gear 5 is connected with the mechanism output shaft through another bevel gear 5, and the other end of mechanism's output shaft is connected with isolating switch.In the utility model, 3 one middle parts that are arranged on drive link 2 of two gear drives, the end that another is arranged on drive link 2, the gear drive 3 in the middle part of being arranged on, its inner power transmission shaft 4 two ends all are connected with drive link 2, and the two is coaxial, sees Fig. 2.
Because the motor-operating mechanism 1 in the utility model is provided with two output shafts; An output shaft is connected with an isolated switch in limit; Another output shaft is connected with drive link 2; Be provided with two gear drives 3 on the drive link 2 and be connected with other two isolated switches respectively, realize that a motor-operating mechanism 1 drives the divide-shut brake of three-phase isolation switch simultaneously.Gear drive 3 in the utility model has adopted two meshed bevel gears 5 to carry out transmission, can change the transmission direction of power, makes three-phase isolation switch be positioned at the same side of drive link 2, and it is reliable and stable that this structure is convenient to the layout and the transmission of isolating switch.The utility model drives three-phase isolation switch respectively with three traditional motor-operating mechanisms 1 and is improved to and drives three-phase isolation switch simultaneously by a motor-operating mechanism 1 and carry out work, simplifies the structure, and has reduced cost.The utility model not only can be used on the isolating switch of combined electrical apparatus and also can be used on the earthed switch, three traditional operating mechanisms moving three-phase earthed switches of generation is improved to an operating mechanism drives three-phase earthed switch ground work.
The utlity model has simple in structurely, reduce cost, have only a motor-operating mechanism just can realize three characteristics that link.
