Abstract
The invention relates to a vacuum circuit breaker body, which comprises an insulated sleeve, an upper flange, a lower flange and a vacuum arc extinguish chamber, wherein the upper flange and the lower flange are respectively arranged at the upper end and the lower part of the insulated sleeve; the vacuum arc extinguish chamber is built in the top of the insulted sleeve; and a moving feeler lever of the vacuum arc extinguish chamber downwards extends out of the shell of the vacuum arc extinguish chamber. The vacuum circuit breaker body has the innovation points that a draw bar which passes through the lower flange is arranged below the vacuum arc extinguish chamber; the draw bar comprises an upper conductive draw bar and a lower insulated draw bar, wherein the top end of the conductive draw bar is connected and fixed with the moving feeler lever of the vacuum arc extinguish chamber; the body of the conductive draw bar is in sliding fit with the lower flange; the lower end of the insulated draw bar is connected with a control mechanism; the top end of the conductive draw bar is connected and fixed with the moving feeler lever of the vacuum arc extinguish chamber; a middle draw body is in sliding fit with the lower flange to realize the purpose of conducting the current of the upper flange and the lower flange when the vacuum arc extinguish chamber is switched on and off; and the original copper conductive sleeve can be omitted so as to lower manufacture cost.
Description
Technical field
The present invention relates to a kind of vacuum body that opens circuit, the low vacuum of the particularly a kind of cost of manufacture body that opens circuit.
Background technology
Vacuum circuit-breaker be few with gas molecule, be difficult for free and vacuum space that dielectric strength is very high novel switched electrical equipment as arc-extinguishing medium.
Vacuum circuit breaker body mainly comprises insulating sleeve, is located at the upper flange and the lower flange of insulating sleeve upper and lower end, and is built in the insulating sleeve and is fixed on the vacuum interrupter at insulating sleeve top.Vacuum interrupter mainly comprises the arc control device housing, place the dynamic and static contact in the housing, fixed contact is connected with upper flange by the stationary contact bar, moving contact is connected with the movable feeler lever that stretches out the housing lower end, the insulating sleeve bottom is equipped with the conductive seat that is connected with lower flange, vertical through hole is opened at this conductive seat center, and movable feeler lever stretches into downwards in the conductive seat and by the watchband fingertip and is slidingly matched.Insulated tension pole that is connected with operating mechanism upwards stretches into the conductive seat top and movable feeler lever is connected and fixed, and drives by operating mechanism that insulated tension pole is upper and lower to be moved, and realizes divide-shut brake by the movable feeler lever that is connected with insulated tension pole.
In order to adapt to user's request, between conductive seat and lower flange, need leave a segment distance, connect by conductive casings between the two, induction coil is sleeved on the detection that conductive casings carries out electric current outward.The shortcoming of this structure is: increased the conductive casings of copper material, improved manufacturing cost.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of cost of manufacture vacuum low and simple in structure body that opens circuit.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of vacuum body that opens circuit, comprise insulating sleeve, be located at the upper flange and the lower flange of insulating sleeve upper end and bottom respectively, and be built in the insulating sleeve and be fixed on the vacuum interrupter at insulating sleeve top, the movable feeler lever of vacuum interrupter stretches out the vacuum interrupter housing downwards, its innovative point is: described vacuum interrupter below be provided with a pull bar that passes lower flange, this pull bar is made up of top conduction pull bar and bottom insulated tension pole, the top of described conduction pull bar and the movable feeler lever of vacuum interrupter are connected and fixed, the body of rod and the lower flange of conduction pull bar are slidingly matched, and the insulated tension pole lower end is connected with operating mechanism.
Further, the center bore inner wall of described lower flange has cannelure, and described cannelure is embedded with and conducts electricity the banded fingertip that pull bar is slidingly connected.
The invention has the advantages that: the top of conduction pull bar and the movable feeler lever of vacuum interrupter are connected and fixed, the middle part body of rod and lower flange are slidingly matched, realize the upper and lower flange current lead-through when vacuum interrupter closes a floodgate, can cancel original copper conductive casings, structure is simple relatively, has reduced cost of manufacture.
