Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present utility model。
Detailed description of the invention
The embodiment of this utility model potting breaker, as it is shown in figure 1, potting breaker includes tank body 4, potting breaker moved end gear device of air。Potting breaker moved end gear device of air, including moved end insulation column 1, moved end insulation column 1 is provided with moved end touch base 2, and the inner chamber of moved end touch base 2 connects with the cavity of moved end insulation column 1。Insulated tension pole 10 passes the cavity of moved end insulation column 1 and is connected with the moving contact pull bar 8 in moved end touch base 2 cavity。Moved end touch base 2 chamber in the inner is provided with interior gear gas 6 and covers, interior retaining hood 6 is provided with mean for moving contact pull bar 8 axially through by mouth, in being provided with the guide ring 7 for coordinating with moving contact pull bar 8 guiding movement by mouth place in interior retaining hood 6。Guide ring 7 is embedded in interior retaining hood 6, moving contact pull bar 8 traverse from this guide ring 7, both close contacts。Guide ring 7 is not only possible to prevent air-flow to pass through but also can play the guiding role。As the guiding to arc-chutes, it is ensured that the centering of moving contact。Interior retaining hood 6 includes the connecting portion 62 for being connected and cover body portion 61 with moved end touch base, cover body portion 61 is tapered, the external diameter in cover body portion 61 is become larger to one end of connecting portion by the one end being provided with mouth, if the axis direction of definition insulated tension pole is left and right directions, namely cover body portion becomes larger from right to left。Air-flow is had an effect for guiding by cone structure。The connecting portion of interior retaining hood is formed by flanging, which is provided with bolt hole。
The bottom (left side) of moved end touch base 2 is provided with steam vent 22, moved end insulation column 1 is additionally provided with outer retaining hood 5, outer retaining hood 5 is in the periphery of moved end touch base 2, and outer retaining hood 5 has the inner chamber of connection steam vent 22, opening moved end insulation column 1 dorsad, opening namely towards right side。Outer retaining hood 5 includes the housing 51 of tubular and the attachment structure 52 for being connected with moved end insulation column, and attachment structure 52 is formed by the in-flanges of housing, and moved end touch base 2 is provided with wire outlet seat 21, and housing is provided with the resigning hole for avoiding described wire outlet seat 21。Interior retaining hood 6, moved end touch base 2, outer retaining hood 5 are bolted on moved end insulation column 1, and the attachment structure of outer retaining hood 5 is between moved end insulation column and moved end touch base。
Moving contact pull bar 8 has the inner chamber for airflow, and moving contact pull bar 8 is communicated with the venthole 81 of the inner chamber of moved end touch base, is provided with the deflection cone 9 that air-flow is guided in moving contact pull bar 8, and the top of deflection cone 9 is directed away from the side of moved end insulation column 1。Deflection cone 9 is positioned at the left side of venthole。
When in chopper interrupting process, the thermal current produced in arc-chutes has two ways to arrive inside moved end, blast of hot air stream is spouting along moving contact pull bar 8 inner chamber, arrives internal under the effect of deflection cone 9, and it is internal that another personal share thermal current directly arrives moved end touch base 2 by relief valve。Thermal current is sprayed onto bottom along the inner chamber of moved end touch base 2, and in bottom under the effect of retaining hood 6, the steam vent ejection of thermal current driven end touch base is directly injected in outer retaining hood 5, without being ejected in moved end insulation column 1 inner chamber。Outside under the effect of retaining hood 5, a part of thermal current has sprayed to the quiet extreme direction of chopper along outer retaining hood 5 opening direction, a part of thermal current is ejected on the inwall of tank body after spraying outer retaining hood, thermal current now have passed through repeatedly to reflect and is cooled sufficiently, will not produce to burn to inner tank wall and form discharge channel, it is prevented that failure of interruption situation occurs。
In this utility model, the gear device of air of retaining hood and outer retaining hood composition both can effectively prevent thermal current to be directly blown onto on the inwall of tank body; prevent thermal current from tank interior being burnt; being possible to prevent again thermal current to blow on moved end insulation column and insulated tension pole, protecting moved end insulation column and insulated tension pole will not burn carbonization because of thermal current and lose insulation effect。
In other embodiments, the cover body portion of interior retaining hood can be configured as cylindrical shape。
The embodiment of this utility model potting breaker moved end gear device of air, this potting breaker moved end gear device of air is identical with the structure that the potting breaker moved end in above-mentioned potting breaker embodiment keeps off device of air, and detailed description of the invention no longer describes in detail。
