Abstract
The utility model discloses a contact box discharge sound elimination structure of a high-voltage switch device. A semiconductor silicone rubber layer (3) is arranged between a gap between an A-phase contact box (1) and a B-phase contact box (2), wherein the semiconductor silicone rubber layer (3) substantially eliminates discharge between an A-phase contact box (1) and a B-phase contact box (2), and thus insulating property and safe reliability of a high-voltage switch cabinet are improved.
Description
Technical field
The utility model belongs to the high voltage switchgear field, relates in particular to a kind of high voltage switchgear and eliminates contact box discharge acoustic structure.
Background technology
In electric power system at present, its handcart type high-voltage switch equipment is by the contact box transition, the up and down busbar to be connected, and has the phenomenon that has the air gap between air gap and contact box and contact box and easily cause the lasting corona of discharge generation between the inwall due to fixed contact and contact box.
The utility model content
Easily cause the defective that discharge generation continues corona phenomenon for having the air gap between contact box and contact box, technical problem to be solved in the utility model is to provide a kind of high voltage switchgear and eliminates contact box discharge acoustic structure.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of high voltage switchgear is eliminated contact box discharge acoustic structure, comprise A phase contact box and B contact box mutually, the space between described A phase contact box and B phase contact box is provided with the semiconductor silicon rubber layer.
Described A phase contact box is provided with A phase housing, and described B phase contact box is provided with B phase housing.
Described A phase contact box and B contact box mutually are square, and described semiconductor silicon rubber layer is bar shaped.
The utility model has the advantage of, because the air gap between A phase contact box and B phase contact box is filled by the semiconductor silicon rubber layer, eliminated the electric discharge phenomena that caused by the air gap, electric discharge phenomena directly affect the insulation property of high-tension switch cabinet and the security reliability of operation.The semiconductor silicon rubber layer has been eliminated the electric discharge phenomena between A phase contact box and B phase contact box greatly, has improved insulating properties and the security reliability of high-tension switch cabinet.
Description of drawings
Fig. 1 is the structural representation that a kind of high voltage switchgear of the utility model is eliminated contact box discharge acoustic structure;
Mark in above-mentioned figure is: 1, A phase contact box, 2, B phase contact box, 3, the semiconductor silicon rubber layer.
Embodiment
Fig. 1 is the structural representation that a kind of high voltage switchgear of the utility model is eliminated contact box discharge acoustic structure, comprise A phase contact box 1 and B contact box 2 mutually, A phase contact box 1 one end openings are fixed on front mounting plate, the tubular insulator of other end sealing is arranged on rear mounting panel, after installing, refill B phase contact box 2, installation method is identical with A phase contact box 1, and the space between described A phase contact box 1 and B phase contact box 2 is provided with semiconductor silicon rubber layer 3.Described A phase contact box 1 is provided with A phase housing, and described B phase contact box 2 is provided with B phase housing.Described A phase contact box 1 and B contact box 2 mutually are square, and described semiconductor silicon rubber layer 3 is bar shaped.
After adopting such structure, air gap between A phase contact box 1 and B phase contact box 2 is filled by semiconductor silicon rubber layer 3, eliminated the electric discharge phenomena that caused by the air gap, electric discharge phenomena directly affect the insulation property of high-tension switch cabinet and the security reliability of operation.Semiconductor silicon rubber layer 3 has been eliminated the electric discharge phenomena between A phase contact box 1 and B phase contact box 2 greatly, has improved insulating properties and the security reliability of high-tension switch cabinet.
The above is exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection range of the present utility model.
