Abstract
The invention discloses an indoor inflation ring main unit with embedded poles. The embedded poles are adopted for a main electricity conducting loop. The indoor inflation ring main unit is composed of an operating mechanism, an inflation box body, upper electricity conducting blocks, an operating shaft, the embedded poles, a mounting plate, lower electricity conducting blocks, an electricity conducting rod, a vacuum arc-extinguishing chamber, an insulation pull rod, a connection plate, a connecting lever and a main bus. In this way, when the indoor inflation ring main unit needs to be switched on, energy of the operating mechanism is released, the operating shaft and the connecting lever fixed to the operating shaft are driven to rotate clockwise, the connecting lever drives the insulation pull rod through the connecting plate to move downwards, a moving contact, fixed to the insulation pull rod, of the vacuum arc-extinguishing chamber is driven to move downwards, and the switching on motion is completed; on the contrary, if the indoor inflation ring main unit needs to be switched off, the connecting lever rotates anticlockwise, the moving contact of the vacuum arc-extinguishing chamber is driven to move upwards, and the switching-off motion is completed. In this way, power supply reliability is improved greatly without increasing the equipment cost.
Description
Technical field
The present invention relates to a kind of indoor Inflatable ring network switch cabinet.
Background technology
Existing indoor Inflatable ring main unit is: cabinet inner breaker body adopts unenclosed construction, namely circuit breaker three-phase vacuum interrupter and electric-conductor are all relative exposed outside (because whole breaker body is installed in airtight insulation box, therefore exposed be relative), dielectric is sulfur hexafluoride gas-insulating.Because the outstanding advantages of Inflatable ring main unit is miniaturized, so alternate and relatively the air of cabinet inner breaker quiet distance relative size is very little; When ring main unit is at specified sulfur hexafluoride gas pressure operation (relative atmospheric pressure is generally 0.04MPa), rated insulation level is completely qualified.When ring main unit leaks air phenomenon, when sulfur hexafluoride gas relative pressure is 0MPa, the quiet distance of air between the parts such as the three-phase vacuum interrupter that existing indoor Inflatable ring main unit is installed and electric-conductor is less, is not enough to play insulating effect, so there will be alternate and phenomenon that is relative ground circuit.When this occurs, only have and change whole indoor Inflatable ring main unit, will certainly equipment cost be increased like this.
Summary of the invention
This patent main purpose is to provide the indoor Inflatable ring main unit that a kind of main conductive circuit adopts pole.
The technical scheme that this patent adopts is: main conductive circuit adopts the indoor Inflatable ring main unit of pole, comprise operating mechanism, Pneumatic box body, upper conducting block, operating axis, pole, mounting panel, lower conducting block, contact rod, vacuum interrupter, insulated tension pole, win in succession, (note: after lower conducting block, vacuum interrupter etc. are as a whole by poured with epoxy resin, is just pole for connecting lever, main bus bar; Wherein, epoxy resin has very strong insulation property.)。It is characterized in that, pole is fixed on Pneumatic box body by mounting panel, be fixed on upper and lower conducting block on pole by bolt respectively with main bus bar and contact rod bolt, reach loop conducting; Operating mechanism is fixed on the outside of Pneumatic box body, and operating mechanism is connected with operating axis, and operating axis is hexagonal insulating rod, and operating axis is fixed with connecting lever, and connecting lever is connected with insulated tension pole by connecting plate, and the other end of insulated tension pole is fixed on the moving contact end of vacuum interrupter.
When indoor Inflatable ring main unit needs to close a floodgate, the combined floodgate fault offset of operating mechanism, operating axis is driven to rotate clockwise, operating axis drives the connecting lever be fixed on above it to rotate clockwise, connecting lever drives insulated tension pole to move downward by winning in succession, because the other end of insulated tension pole is fixed on the moving contact end of vacuum interrupter, thus the moving contact of vacuum interrupter moves downward and contacts with the fixed contact of vacuum interrupter, and feed motion completes.Otherwise, when indoor Inflatable ring main unit needs separating brake, the separating brake fault offset of operating mechanism, operating axis is driven to rotate counterclockwise, operating axis drives the connecting lever be fixed on above it to rotate counterclockwise, connecting lever drives insulated tension pole to move upward by winning in succession, thus the moving contact of vacuum interrupter moves upward and to be separated with the fixed contact of vacuum interrupter, and separating brake action completes.So, even if when sulfur hexafluoride gas in Pneumatic box body occurs that the force value after revealing is 0MPa (relative value), because the elements such as the vacuum interrupter that the quiet distance of air is less are all coated in pole, insulation level is revealed in sulphur hexafluoride force value also can meet insulating requirements for time 0MPa (relative value), thus guarantee power supply reliability, be filled with insulating gas in time, without the need to more exchange device.Like this under the prerequisite not increasing equipment cost, substantially increase the reliability of power supply.
The main conductive circuit that this patent provides adopts the indoor Inflatable ring main unit of pole, when indoor Inflatable ring main unit needs to close a floodgate, the combined floodgate fault offset of operating mechanism, operating axis is driven to rotate clockwise, operating axis drives the connecting lever be fixed on above it to rotate clockwise, connecting lever drives insulated tension pole to move downward by winning in succession, because the other end of insulated tension pole is fixed on the moving contact end of vacuum interrupter, thus the moving contact of vacuum interrupter moves downward and contacts with the fixed contact of vacuum interrupter, feed motion completes.Otherwise, when indoor Inflatable ring main unit needs separating brake, the separating brake fault offset of operating mechanism, operating axis is driven to rotate counterclockwise, operating axis drives the connecting lever be fixed on above it to rotate counterclockwise, connecting lever drives insulated tension pole to move upward by winning in succession, thus the moving contact of vacuum interrupter moves upward and to be separated with the fixed contact of vacuum interrupter, and separating brake action completes.

Embodiment
Below in conjunction with accompanying drawing, this patent is described further.
In figure: 1, operating mechanism 2, Pneumatic box body 3, upper conducting block 4, operating axis 5, pole 6, mounting panel 7, lower conducting block 8, contact rod 9, vacuum interrupter 10, insulated tension pole 11, win 12 in succession, connecting lever 13, main bus bar
As shown in Figures 2 and 3, this patent main conductive circuit adopts the indoor Inflatable ring main unit of pole, comprises operating mechanism 1, Pneumatic box body 2, upper conducting block 3, operating axis 4, pole 5, mounting panel 6, lower conducting block 7, contact rod 8, vacuum interrupter 9 insulated tension pole 10, wins 11 in succession, connecting lever 12, main bus bar 13.Pole 5 is fixed on Pneumatic box body 2 by mounting panel 6, be fixed on the upper conducting block 3 on pole 5, lower conducting block 7 by bolt respectively with main bus bar 13 and contact rod 8 bolt, reach loop conducting; Operating mechanism 1 is fixed on the outside of Pneumatic box body 2, operating mechanism 1 is connected with operating axis 4, operating axis 4 is hexagonal insulating rod, operating axis 4 is fixed with connecting lever 12, connecting lever 12 is connected with insulated tension pole 10 by connecting plate 11, the other end of insulated tension pole 10 is fixed on the moving contact end of vacuum interrupter 9, and whole like this vacuum interrupter and insulated tension pole etc. are all coated by epoxy resin, considerably increase insulation property.
