Abstract
The present invention relates to a domestic AC high-voltage sealing load switch. The sealing performance of the present invention can be guaranteed, and the reliability of the load switch is good. The present invention comprises a cylindrical insulating casing and an operating mechanism, wherein a moving contact, fixed contacts and a grounding contact are arranged in the casing; the moving contact is arranged on a main shaft; the fixed contacts and the grounding contact are connected to the inner wall of the casing; the fixed contact are respectively distributed at both sides of the moving contact; the fixed contacts at one side are connected with input terminals, and the fixed contacts at the other side are connected with outlet terminals; the main shaft extends out of the casing through a dynamic seal system and is connected with the operating mechanism; sulphur hexafluoride is filled in the casing. The present invention is characterized in that the cylindrical insulating casing is a casting cylindrical whole body.
Description
(1) technical field
The present invention relates to appliance switch, be specially indoor AC high-voltage closed load switch.
(2) background technology
Existing indoor AC high-voltage closed load switch, it comprises tubular insulation shell and operating mechanism, be provided with moving contact, fixed contact and grounding contact in the described housing, described moving contact is installed on main shaft, described fixed contact, grounding contact are connected in the inwall of housing and are distributed in the sidepiece of moving contact, described main shaft stretches out housing by the movable sealing system and is connected with operating mechanism, is filled with sulphur hexafluoride in the described housing.The shortcoming of this on-load switch is exactly: its tubular insulation shell is to connect with semicircle cell body Hough, because the combination seal face between the two semi-circular groove bodies is bigger, sealing is difficult to guarantee the poor reliability of on-load switch.
(3) summary of the invention
At existing indoor AC high-voltage closed load switch, combination seal face between the two semi-circular groove bodies of its tubular insulation shell is bigger, sealing is difficult to guarantee, the shortcoming of the poor reliability of on-load switch, the invention provides another indoor AC high-voltage closed load switch, its sealing property can be guaranteed, the good reliability of on-load switch.
Its technical scheme is such: it comprises tubular insulation shell and operating mechanism, be provided with moving contact in the described housing, fixed contact and grounding contact, described moving contact is installed on main shaft, described fixed contact, grounding contact is connected in the inwall of housing, described fixed contact is distributed in the both sides of described moving contact respectively, the fixed contact of one side connects input terminal, the fixed contact of opposite side connects outlet terminal, described main shaft stretches out housing by the movable sealing system and is connected with operating mechanism, be filled with sulphur hexafluoride in the described housing, it is characterized in that: described tubular insulation shell is a tubular integral body of die casting; Described movable sealing system comprises translucent cover, and described translucent cover is set in described main shaft, is provided with two sealing rings in the junction of described translucent cover and described main shaft, is filled with sealing oil between described two sealing rings.
It is further characterized in that: in described housing, the outlet terminal place of described fixed contact is provided with coil, and described coil connects display.
The present invention adopts after the said structure, the tubular insulation shell changes rheo-die-casting into by original Hough connection and becomes a tubular integral body, the sealing surface that is connected much smaller than Hough of the end of the open end of tubular insulation shell and sealing surface between the subsequent parts like this, its sealing property can be guaranteed, the good reliability of on-load switch; And the end of tubular insulation shell is provided with translucent cover, can observe the operate condition of inner each parts of on-load switch at any time, further guarantees the reliability of on-load switch; The coil that the grounding contact place is provided with can pass to display with induced signal, whether switch on to judge grounding contact, the same reliability that further guarantees on-load switch, thereby avoided existing indoor AC high-voltage closed load switch, combination seal face between two semi-circular groove of its tubular insulation shell is bigger, sealing property is difficult to guarantee the shortcoming that the reliability of on-load switch is also poor.

Fig. 2 is that the A-A of shell 1 among Fig. 1 is to cutaway view;
Fig. 3 is that the B of translucent cover among Fig. 1 is to schematic diagram;
Fig. 4 be the C-C of Fig. 3 to revolved sectional view, in order to know expression structure, Fig. 4 amplifies in proportion.
(5) embodiment
See Fig. 1, Fig. 2, Fig. 3, Fig. 4, the present invention includes tubular insulation shell 1 and operating mechanism, be provided with moving contact 2 in the housing 1, fixed contact 3,11 and grounding contact 4, moving contact 2 is installed on main shaft 10, fixed contact 3,11, grounding contact 4 is connected in the inwall of housing 1, fixed contact 3,11 are distributed in the both sides of moving contact 2 respectively, fixed contact 3 connects input terminal 5, fixed contact 11 connects outlet terminal 9, main shaft 10 stretches out housing 1 by the movable sealing system and is connected with operating mechanism 7, be filled with sulphur hexafluoride in the housing 1, tubular insulation shell 1 is a tubular integral body of die casting.The movable sealing system comprises translucent cover 6, sees Fig. 3, Fig. 4, and translucent cover 6 is set in main shaft 10, is provided with between 14,15, two sealing rings 14,15 of two sealing rings in the junction of translucent cover 6 and main shaft 10 and is filled with sealing oil; In the housing 1, outlet terminal 9 places of fixed contact 11 are provided with coil 8, and coil 8 connects display (not expressing display among Fig. 1).12 is that Inflation door, 13 is the valve obstruction.Below in conjunction with Fig. 1 course of action of the present invention is described: operating grip is inserted in the operating mechanism 7 on-load switch handle holes, turn clockwise, the energy storage and the release of the main spring by operating mechanism, main shaft 10 fast rotational of moving contact 2 are equipped with in drive, firmly be connected with input terminal 5, outlet terminal 9 until moving contact 2, make on-load switch be in "on" position, electric energy is carried by switch and is distributed, when the needs separating brake, operating grip is rotated counterclockwise on-load switch, the conveying of interrupt power and distribution; If next section of on-load switch breaks down with electric line or electrical appliance, when needing repairing, make on-load switch be in gate-dividing state earlier, then operating grip is inserted in the handle hole of earthed switch and turns clockwise (the structure of each parts of operating mechanism 7 and annexation is installed belongs to prior art, do not express the on-load switch handle hole among Fig. 1, the handle hole of earthed switch), compressed energy-storage and release by the operating mechanism ground spring, drive is equipped with main shaft 10 fast rotational of moving contact 2 until moving contact 2 and outlet terminal 9, grounding contact 4 firmly connects, make on-load switch be in ground state, to guarantee maintenance personal's personal safety; And the rotation status of main shaft 10 can be understood from translucent cover at any time, and the running status of on-load switch can be understood from display, thereby guarantees the reliable of on-load switch.
