The isolation switch and the grounding functional part can both obtain different opening and closing states through the operation of the same rotating shaft; thereby, the utility model has the advantages that the structure is simple, the operation is convenient, the size is small when matched with a cabinet, the space is saved, the flexibility is increased, and the utility model can satisfy various types requirements.
Description
The utility model relates to the wall-penetrating type isolating switch that is suitable for the usefulness of the isolation between electric equipment and power supply in the 10-35KV electrical network.
The typical model of existing wall-penetrating type isolating switch mainly contains GN19, GN28 etc., and each of GN19, GN28 is formed insulation component, formed the plug-in strip of operating mechanism and divide-shut brake and main body underframe etc. by insulated tension pole, rotating shaft and constitute by a wall-penetrating type porcelain bushing, supporting insulator.The difference of these two kinds of isolating switches is: the route that electric current flows through at GN19 during closure state is one to be 90 ° broken line, and promptly the conductor and the plug-in strip of the porcelain bushing by wall-penetrating type are 90 ° of layouts, and its underframe is a plane; And the electric current that flows through GN28 is a direction linearly, and promptly conductor and the plug-in strip by the wall-penetrating type porcelain bushing is straight line, and its underframe is " L " type; Two kinds of different method for arranging are mutual complementations.Both all can increase a rotating shaft and ground connection knife plate and become the isolating switch with band earthed switch function, when being operated, this isolating switch with band earthed switch function need two connecting rods to operate respectively, need to increase a rotating shaft, make structure complicated, GN28 join cabinet when using shared volume big, when using, reality lacks flexibility, so seldom select for use.
Task of the present utility model be to provide a kind of simple in structure, take that volume is little, flexibility strong, can satisfy the isolating switch of various types needs.
Task of the present utility model is finished as follows: isolating switch is supported in the insulation of wall-penetrating type list, comprise underframe, be installed in the three phase isolated element on the underframe, carry out every phase conductive component of divide-shut brake by operating mechanism, it is characterized in that described insulation component is the opening-like insulating sleeve in upper end, the conductive component of every phase supports by insulating sleeve separately.
Described conductive component is made up of plug-in strip, fixed contact, copper bar, the insulated connecting rod of plug-in strip and operating mechanism is hinged, hinged by shipping and reselling on another market simultaneously with copper bar, and copper bar is located in the insulating sleeve, its upper end is connected the insulating sleeve middle part by pin, the lower end is connected with support, and fixed contact I is fixed on the contact base of insulating sleeve upper end.
Described operating mechanism comprises two supports rotating rotating shaft on underframe, is fixed with connecting lever I in the rotating shaft, and insulated connecting rod one end and connecting lever I are hinged, and the other end and plug-in strip are hinged.
Isolating switch also has the grounding function parts of being made up of fixed contact II, connecting lever II, ground connection knife plate, every phase fixed contact II connects with every support mutually, be fixed with connecting lever II in the rotating shaft, the connecting lever II other end and ground connection knife plate are fixed, the ground connection knife plate can with fixed contact II deciliter.
Its each all mutually live part of the utility model isolating switch is by insulating sleeve support separately, thereby can save the insulator of supporting static contact isolation switch and fix the corresponding underframe of this insulator position, volume shared when joining the cabinet use is little, and having saved the space has increased flexibility; To having the isolating switch of band earthed switch function, because of a shared rotating shaft, thereby only need an action bars just can carry out isolating switch and earthed switch is operated simultaneously, saved the interlock on the operating mechanism, make simple in structurely, easy to operate, compare with GN19, the GN28 of identical function, the part number is wanted much less, can satisfy the isolating switch of various types needs.
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1 is a wherein phase sectional structure schematic diagram of the utility model.
Fig. 2 is the right view (three-phase Pareto diagram) of Fig. 1.
Referring to Fig. 1-2, the insulation of wall-penetrating type list supports that isolating switch includes a underframe (6), and three phase isolated sleeve pipe (13) is installed on the underframe, and this insulating sleeve upper end is the half opening shape, by being bolted on the underframe.The conductive component of every phase is made up of plug-in strip (3), fixed contact I (2), copper bar (12), all supports from separately insulating sleeve.Plug-in strip in the conductive component (3) is hinged on the middle part with the insulated connecting rod (4) of operating mechanism, one end rotates with the hinged pin that rotates of copper bar (12) by ship and resell on another market (15), and copper bar interts in insulating sleeve, its upper end is connected the insulating sleeve middle part with pin (14), the lower end be buckled in insulating sleeve at the bottom of on support (11) be connected, the fixed contact I (2) of pressure mouth formula is fixed on the contact base (1) of insulating sleeve upper end.
The operating mechanism of finishing the isolating switch divide-shut brake comprises that two supports is in upward rotating rotating shaft (5) of underframe (6), weld 3 connecting lever I (7) by three phase positions in the rotating shaft, each connecting lever I and each insulated connecting rod (4) one ends are hinged, the other end of insulated connecting rod and plug-in strip (3) are hinged, if rotating shaft is subjected to counterclockwise torsion, by insulated connecting rod plug-in strip upwards being rotated counterclockwise enters in the fixed contact I, this moment, isolating switch was in "on" position, and electric current forms path through contact base, fixed contact I, plug-in strip, copper bar, support.
If when needing to increase grounding function, the grounding function parts of being made up of fixed contact II (10), connecting lever II (8), ground connection knife plate (9) also can be installed, concrete every phase fixed contact II (10) connects with every support mutually (11), in rotating shaft (5), increase weldering 2 connecting lever II (8), the ground connection knife plate (9) of the other end of connecting lever II and strip is fixing, and the ground connection knife plate can be grounded function with fixed contact II deciliter.When rotating shaft was rotated, when plug-in strip was in closing position, the ground connection knife plate was in ground connection separating brake position away from the fixed contact II on the support; When plug-in strip was in the separating brake position, the ground connection knife plate entered fixed contact II and is in the contact of earth position, only need operate same rotating shaft during operation and can realize above-mentioned two kinds of functions.
