Description
Technical field
The utility model relates to the power distribution equipment technical field of wind power generation, particularly wind electric converter rack cable sealing device.
Background technology
Present stage, wind power generation was due to the new forms of energy characteristic of its environmental protection, obtained at home in recent years development at full speed, large-scale wind power plant at home construction gradually gets up, and Wind Power Plant at Sea is at home because the restriction of key technology is essentially blank.Due to the particularity of offshore conditions, the restriction of the factors such as for example salt air corrosion, humidity, plant maintenance difficulty, and China's wind power equipment manufacturing industry is started late, Offshore Wind Power Generation Technology relatively lags behind, and solving Oversea wind power generation key technology is the urgent task of China's wind-driven generator technical development.At the bottom of most of land blower fan tower, current transformer rack is most of at present uses oil immersion to seal, to avoid the infringement of nature or human factor.If but offshore wind generating still adopts this kind of mode, the larger converter system equipment of volume needs larger sea to install and operating platform, greatly increase the cost of offshore wind turbine, and due to the impact of the factors such as marine salt air corrosion, humidity, can significantly shorten the useful life of the electric equipments such as transformer, and regular maintenance expense is also high.
Summary of the invention
The purpose of this utility model is for the defect of prior art and deficiency, and a kind of compact conformation, wind electric converter rack cable sealing device easy to maintenance are provided.
For achieving the above object, the utility model is by the following technical solutions:
Wind electric converter rack cable sealing device described in the utility model, comprise cabinet, the sidewall of cabinet is provided with cable hole, in described cable hole, be equipped with sealing wire clamp, sealing wire clamp is provided with wedged hole, in wedged hole, be equipped with the clamp piece that two pairings arrange, potted line underedge end is arranged with gum cover, and the inwall of gum cover is provided with the chock plug coordinating with clamp piece.
Further, the lateral wall of described clamp piece is provided with the inclined-plane coordinating with wedged hole, on the madial wall of clamp piece, has through wires hole, and two clamp pieces are symmetrically set in wedged hole and its madial wall that has through wires hole is oppositely arranged.
Further, the inwall of described through wires hole is provided with anti-slip veins.
Further, the tail end of described clamp piece is provided with semi-moon shaped tapered end, and the outer rim of tapered end is provided with external screw thread.
Further, described sealing wire clamp is provided with fixed head, is equipped with some set bolts on fixed head.
The utility model beneficial effect is: the utility model is rational in infrastructure, two clamp pieces pass sealing wire clamp after clamping cable, by the bevel friction power of wedged hole, cable is fixed in cable hole, the deadweight of external cable makes clamp piece stable connection, the inner end of sealing wire clamp is arranged with the space between gum cover shutoff clamp piece, improve the sealing of cabinet, long service life easy to maintenance.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Wind electric converter rack cable sealing device described in the utility model, comprise cabinet 1, the sidewall of cabinet 1 is provided with cable hole 11, in described cable hole 11, be equipped with sealing wire clamp 2, sealing wire clamp 2 is provided with wedged hole 21, in wedged hole 21, be equipped with the clamp piece 3 that two pairings arrange, cable is arranged between two clamp pieces 3, clamp piece 3 penetrates wedged hole 21, thereby sealing wire clamp 2 forms extruding clamping cables line to clamp piece 3, sealing wire clamp 2 inner ends are arranged with gum cover 22, the inwall of gum cover 22 is provided with the chock plug 23 coordinating with clamp piece 3, in space between two clamp pieces 3 by chock plug 23 shutoff, thereby make to seal the inside and outside maintenance isolation of cabinet 1 of wire clamp 2 both sides, avoid extraneous corrosive medium to enter cabinet 1 and affect inner converter system equipment.
The lateral wall of above-mentioned clamp piece 3 is provided with the inclined-plane coordinating with wedged hole 21, on the madial wall of clamp piece 3, have through wires hole 31, two clamp pieces 3 are symmetrically set in wedged hole 21 and its madial wall that has through wires hole 31 is oppositely arranged, clamp piece 3 slips into sealing wire clamp 2 by the inclined-plane of lateral wall along wedged hole 21, between clamp piece 3 and cable, be fixed in sealing wire clamp 2 by frictional force, outside cable deadweight makes clamp piece 3 and sealing wire clamp 2 stable connections.
The inwall of above-mentioned through wires hole 31 is provided with anti-slip veins, and through wires hole 31 keeps being closely connected by anti-slip veins and cable, avoids cable at clamp piece 3 intrinsic displacements.
The tail end of above-mentioned clamp piece 3 is provided with semi-moon shaped tapered end 32, and the outer rim of tapered end 32 is provided with external screw thread, on tapered end 32, can be socketed clamp nut, thereby improves the bonding strength between clamp piece 3 and cable, avoids the cable line end in cabinet 1 to produce displacement.
Above-mentioned sealing wire clamp 2 is provided with fixed head 24, is equipped with some set bolts 25 on fixed head 24, and sealing wire clamp 2 is connected on cabinet 1 by fixed head 24 and set bolt 25.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
