Abstract
The utility model discloses an indoor AC high-voltage enclosed load switch. End cap of the load switch is transparent so that working condition of each contact and instantaneous situation of closing/opening inside the load switch can be observed at any moment, so as to analyze and appraise switch quality according to operation situation, avoid occurrence of accident in time and guarantee reliability of load switch. It includes cylindrical insulation casing and operating mechanism; movable contact, static contacts and grounding contact are disposed in the casing; the movable contact is installed on main axis; the static contacts and grounding contact are connected to inner wall of the casing; the static contacts are respectively distributed on two sides of the movable contact; one static contact on one side is connected with input terminal, and the other static contact is connected with output terminal; the main axis is connected with the operating mechanism after penetrating the end cap connected with the casing; and sulfur hexafluoride is filled in the casing. The utility model is characterized by transparency of the end cap.
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: the movable sealing system of its tubular insulation shell and end is totally-enclosed shape, no visual windows, well whether on-load switch in use contact between each contact, put in place like this, whether there is the size of electric arc generation and electric arc all can't understand during switch motion, therefore can't evaluate the running quality and the running status of switch, generation that can't the prevention apparatus accident, security reliability is relatively poor.
(3) summary of the invention
At existing indoor AC high-voltage closed load switch, the movable sealing system of its tubular insulation shell and end is totally-enclosed shape, no visual windows, whether on-load switch in use contacts good between each contact like this, put in place, whether there is the size of electric arc generation and electric arc all can't understand during switch motion, running quality and running status to switch can't be evaluated, generation that can't the prevention apparatus accident, the shortcoming that security reliability is relatively poor, the utility model provides another indoor AC high-voltage closed load switch, it can in time be evaluated the running quality and the running status of switch, and security reliability is better.
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 is connected with operating mechanism after passing the end shield that is connected with described housing, be filled with sulphur hexafluoride in the described housing, it is characterized in that: described end shield is visual end shield.
It is further characterized in that: described visual end shield is a translucent cover; Described visual end shield is a plastic jacket, and described plastic jacket is provided with observation window; In the junction of described end shield and described main shaft, described end shield is provided with two sealing rings, is filled with sealing oil between described two sealing rings, and in described housing, the outlet terminal place of described fixed contact is provided with coil, and described coil connects display.
In the said structure of the present utility model, end shield is visual end shield, the working condition switch that can observe inner each contact of on-load switch so at any time is in the instantaneous situation of folding, can analyze, evaluate the quality of switch like this according to operation conditions, can timely trouble-saving generation, guarantee 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, the movable sealing system of its tubular insulation shell and end is totally-enclosed shape, no visual windows, can't understand on-load switch situation in use like this, the shortcoming that the security reliability of switch is relatively poor.
