Technical purpose of the present utility model is to overcome the deficiencies in the prior art, and a kind of low pressure concentration bus duct joint degree of protection structure is provided, and this structure is easy to assembly, sealing is reliable, has guaranteed the reliability that bus duct is in operation.
In order to reach above-mentioned technical purpose, the utility model is realized by following technical scheme:
A kind of low pressure concentration bus duct described in the utility model joint degree of protection structure, comprise and be installed in the bus duct busbar up and down and the just envelope piece between the inwall of bus groove case two sides, the described two sides of just sealing piece all cooperate with the internal face of corresponding side surface by side seal piece and side plate successively, the described bottom of just sealing piece also cooperates with the bottom of side plate, be provided with one first sealing gasket between the side of the described side of just sealing piece and side seal piece and between the bottom of the described bottom of just sealing piece and side plate, be provided with second sealing gasket between the side of described side seal piece and the side plate side, be provided with the 3rd sealing gasket and a ground wire connecting plate between the end internal face of described bus groove case end.
As the further improvement of above-mentioned technology, the described piece that just sealing also can be by being made up of two parts, and it comprises that first of upper and lower settings just sealing piece and second and just sealing piece.
As the further improvement of above-mentioned technology, described side plate is U-shaped plate, and corresponding with it, described first sealing gasket is U-shaped design, passes through mould molding.
In the utility model, the described piece, side seal piece of just sealing adopts and mills pin or casting or section bar and process; In addition, described ground wire connecting plate adopts section bar to be made, like this, and the quality of fit when just guaranteeing to assemble.
Technology is compared, and the beneficial effects of the utility model are:
(1) the utility model has guaranteed agility and the efficient of assembling owing to by just sealing piece, side seal piece, side plate and ground wire connecting plate and placing the sealing gasket of each junction to seal, during installation, need not to reach in advance to beat the glue encapsulation process afterwards;
(2) piece, side seal piece of just sealing of the present utility model adopts and mills pin or casting or section bar and process, described ground wire connecting plate adopts section bar, each sealing gasket also is mould molding, therefore, it seals by the structure between each parts and sealing gasket fully, have the better seal effect, sealing is reliable, has guaranteed the reliability that bus duct is in operation.
