The utility model relates to the technical field of converter transformer vacuum oil, particularly relates to the air chamber vacuumized for converter transformer.
Background technology
Converter transformer must vacuumize during oiling in installation or maintenance process, and converter transformer volume is large, pipeline is complicated, and the dead angle vacuumizing oiling is more, does not slightly note causing residual bubble, so just must do over again.At present, vacuumizing before converter transformer oiling still mainly takes conventional method, namely uses and vacuumizes flexible pipe and be connected with evacuator by the valve at converter transformer body conservator place, vacuumized by more single to converter transformer entirety.Visible, the existing this mode efficiency vacuumized is lower, and easily causes residual bubble and do over again, and then causes construction delay.
Summary of the invention
The purpose of this utility model is overcoming above-mentioned prior art Problems existing, proposes a kind of air chamber vacuumized converter transformer from multiple point, avoids the formation of residual bubble, improves the efficiency that converter transformer vacuumizes.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows:
For the air chamber that converter transformer vacuumizes, comprise the air chamber cavity of vacuum-resistant, described air chamber cavity is provided with at least two changes of current be connected with converter transformer and becomes vacuum tube, and the vacuum-pumping tube to be connected with outside evacuator, the described change of current becomes on vacuum tube and vacuum-pumping tube and is respectively equipped with valve.
The change of current of two or more change vacuum tube is connected to simultaneously each vacuum-pumping valve on converter transformer, vacuum-pumping tube is connected evacuator simultaneously, and the valve opened on these changes of current change vacuum tube and vacuum-pumping tube, close the valve on untapped pipe, start evacuator, can be vacuumized from multiple spot converter transformer by air chamber cavity simultaneously, reduce the dead angle vacuumized, avoid the formation of residual bubble, improve the success rate that converter transformer vacuumizes, the speed simultaneously vacuumized is faster, has saved the time.
Be provided with oil exit pipe in the bottom of described air chamber cavity, described oil exit pipe is provided with draining valve.Discharge the oil poured in down a chimney in air chamber cavity by oil exit pipe in time, ensure the stability of air chamber work.
Described air chamber cavity is also provided with oil level indicator.Can observe in air chamber cavity whether have oil and long-pending oil number so that oil extraction in time.
The described air chamber vacuumized for converter transformer is at least provided with the vacuum-pumping tube described in two.The evacuator of different model can be coordinated, expand the scope of application.
Described air chamber cavity is cylindrical barrel shape.Compare other shape, its capacity is comparatively large, and easily manufactures, and sealing is better, and compressive resistance is high, and materials are less.
The barrel surface of described air chamber cavity is provided with channel-section steel bar.The compressive resistance of air chamber cavity can be increased.
The described air chamber vacuumized for converter transformer also comprises the base for fixing described air chamber cavity.
The utility model has the advantages that: can be vacuumized from multiple spot converter transformer by air chamber cavity simultaneously, reduce the dead angle vacuumized, avoid the formation of residual bubble, improve the success rate that converter transformer vacuumizes, the speed simultaneously vacuumized is faster, has saved the time; Can also drain the oil poured in down a chimney in time, ensure job stability, and the performances such as applied widely, simple and reasonable for structure, easily manufactured, withstand voltage, sealing are good.
