Abstract
The utility model relates to an indoor AC high-voltage closed load switch which has guaranteed sealing property and good reliability for the load switch. The utility model comprises a cylindrical insulating shell body and an operating mechanism, wherein a moving contact, static contacts and a grounded contact are arranged inside the shell body. The moving contact is installed on a principal axis, and the static contacts and the grounded contact are connected with the inner wall of the shell body. The static contacts are respectively distributed on both sides of the moving contact, and the static contact on one side is connected with an input terminal, and the static contact on the other side is connected with an output terminal. The principal axis extends out of the shell body through a moving seal system and is connected with the operating mechanism, and sulphur hexafluoride is filled in the shell body. The utility model is characterized in that the cylindrical insulating shell body is a cylindrical entire body through die casting.
Description
(1) technical field
The utility model relates to appliance switch, is 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 utility model 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.
It is further characterized in that: 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; In described housing, the outlet terminal place of described fixed contact is provided with coil, and described coil connects display.
The utility model 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.
