Abstract
Encapsulated switch disconnector arrangements are increasingly used in medium-voltage switching installations. The reason for this is that they occupy a smaller amount of space than large-volume, air-insulated switching cells. The object now exists of accommodating all the important parts in a single, encapsulated housing, of further reducing the number of parts and of reducing the cost for the arc extinguishing device, with the same performance capability as the previous devices. The invention specifies an encapsulated switch disconnector arrangement in the case of which the moving contact piece is constructed as a double disconnecting blade (isolating blade) 1 and can be switched into three positions, and the extinguishing device consists of arc splitters 4 which are arranged in overlapping layers parallel to a busbar 12 (which is laid in the interior of the housing 9) in such a manner that the arc which is produced during the switching-off movement of the double isolating blade is bounded by a cohesive cooling surface. Such an encapsulated switch disconnector arrangement can be used in a plurality of configurations and for the R, Y and B phases in an encapsulated housing 9 which is filled with sulphurhexafluoride (SF6), it preferably being possible to use such a switching installation in mains power supply distribution stations.
Description
The invention relates to the load-break switch in being full of the closure of sulphur hexafluoride.
In power engineering, controller switching equipment is used to hold switching device and relevant operation, protection and control device.The function of controller switching equipment is: the electric energy that the power station is sent; be transformed to the electric energy of high pressure or low pressure and monitor in transformer station by the electric energy that electrical network offers the user; equipment and each several part are switched on and off, and when breaking down, protect them to avoid bigger infringement.In 1 to 3KV mesohigh scope, the required installing space of controller switching equipment is less than big capacity air insulated switch element, thereby more is applicable to the electrical network distribution substation of exploitation recently.Controller switching equipment adopts the advantage of enclosed construction to comprise: not only have and prevent the protective effect that contacts with moisture with the contact of movable part and dust, and make installation compactness more.In the mesohigh scope, sulphur hexafluoride is a kind of special good insulation performance and switch medium.SF
6Being the inert gas that a kind of insulating capacity is higher than 2.5 times of air, is a kind of electronegative gas with high-termal conductivity, and it also is applicable to arc extinguishing.
A sealing be filled with sulphur hexafluoride (SF
2) shell in be provided with a fixed contact and the mobile contact that can on three positions, change and the load-break switch of a bus and in DE-OS2729571, disclose.In this case, load-break switch is enclosed in the metal shell.
Each load-break switch all has arc-control device and the special-purpose earthed switch of oneself.Load-break switch has a current collector that exists with mobile contact plug form.Arc-control device comprises the withstand voltage sealing arc control device of a sealing, preferably is full of Compressed Gas.The bus that is used to power is contained in the metal shell spaced apart bus bars indoor.Therefore, between each metal shell and bus-bar room, need special sealing.
The present invention is based on following task: the quantity that reduces part in the enclosed load-break switch unit, in an independent closure, hold the cost (with comparing of present use) of whole critical pieces and reduction arc-control device, should guarantee original performance simultaneously.
The present invention is realized by following scheme: be filled with sulphur hexafluoride (SF a sealing
6) shell in be provided with a fixed contact and the mobile contact that can on three positions, change and the load-break switch of a bus, it is characterized in that: mobile contact is as two disjunction plug-in strips 1, its run-on point 16 is located on the center sleeve of a sleeve pipe 15, and this point is used as the strong point of two disjunction plug-in strips 1 simultaneously; This pair disjunction plug-in strip 1 can utilize a drive unit that is located at shell 9 outsides to change, and this transmission device is connected with this pair disjunction plug-in strip 1 by a connecting rod 10, and the driving shaft 11 that wherein is used for connecting rod 10 is incorporated into shell 9 airtightly; And bus 12 is fixed on the post insulator 13 that insulating material does in the inside of shell 9, and this post insulator 13 is connected with shell 9 via the setting element 14 of a strutting piece; And two disjunction plug-in strips 1 and affiliated known arc-control device (4 to 8) itself thereof are fixed on the bus 12.
The good effect that the present invention obtained is: created a kind of load-break switch unit of safeguarding of not needing basically, owing to have the architectural feature of individual components it can have been made economically.The particularly important is bus in this respect and also be merged in the shell, and switchblade knife also is used for earthing device, just cancelled the additional locking device between load-break switch and the earthing device thus.Because the size of using arc chute can dwindle arc-control device, in addition, can be made simply and be incorporated into according to arc-control device of the present invention and be need not further repacking in the existing system.
The accompanying drawing that proposes a design example below also is illustrated in more detail.Accompanying drawing is as follows:
Fig. 1: enclosed load-break switch unit, end view;
Fig. 2: arc-control device, end view;
Fig. 3: arc-control device, vertical view;
Fig. 4: have the complete controller switching equipment of several three utmost point load-break switch, front view;
Fig. 5: same controller switching equipment, end view.
Because each load-break switch all has identical structure, Fig. 1 only expresses a load-break switch unit.This load-break switch comprises a current collector that constitutes with the form of two section breaker plug-in strips 1.Two section breaker plug-in strips have 2, one earthing contacts 3 of a fixed contact and an arc-control device that is made of arc chute.Fixed contact directly links to each other with bus 12 against arranging also mutually with arc-control device.Electric power is added on two section breaker plug-in strips 1 by the sleeve pipe 15 that is arranged in shell 9 walls.Support of the two section breaker plug-in strips of the part double as of sleeve pipe in wall and fulcrum.Two section breaker plug-in strips have three position of the switch, as closure, and " leading to " position, two herein section breaker plug-in strips contact with fixed contact 2; The position of " breaking ", two herein section breaker plug-in strips are in the position between fixed contact 2 and the earthing contact 3; Be " ground connection " position at last, two section breaker plug-in strips contact with earthing contact.Earthing contact 3 directly is connected on the wall of shell 9.Two section breaker plug-in strips directly link to each other with connecting rod 10, and they are coupled on the driving shaft 11 of outside, unit.Bus 12 is installed on the post insulator 13, is connected to post insulator setting element 14 on the wall of shell 9.Arc-control device comprises the sidewall 5 of two flutings, and arc chute inserts in this sidewall 5.Two sidewalls are connected by connecting plate 6.Hole 7 can be inserted for setting element 8, and formation is connected with bus 12.
Fig. 4 and Fig. 5 represent the profile of a complete controller switching equipment.Sleeve pipe 15 is drawn from the front, and the input cable links to each other with connector 18 herein.In order to save the space, this sleeve pipe is arranged sideling.
