Abstract
The utility model provides a high current insulation contact box with a heat radiation channel. The high current insulation contact box comprises a cylinder body. The bottom of the cylinder body is closed, and the top of the cylinder body is provided with a wire inlet. The cylinder body is provided with a wire outlet which is vertically connected with the cylinder body. The wire outlet is communicated with the inner cavity of the cylinder body. The side wall of the cylinder body is also provided with a heat radiation channel which is communicated with the inner cavity of the cylinder body and the outside of the cylinder body. The heat radiation channel is on the side wall of the cylinder body opposite to the wire outlet. Since the side wall of the high current insulation contact box is provided with the heat radiation channel which is communicated with the inner cavity of the cylinder body and the outside of the cylinder body, the temperature of the air in the contact box is reduced, the high current insulation contact box has good heat radiation performance, the heat generated by a contact can be rapidly radiated, the contact is maintained in a good working environment, thus a short circuit accident is avoided, and the overall performance and the service life of a switch cabinet are improved.
Description
Technical field
The utility model belongs to the switch cubicle technical field, relates to a kind of contact box, particularly a kind of large electrical insulation contact box.
Background technology
Contact box is the moulding of epoxy resin technology pressure gel, for various handcart switch cabinets, plays the insulation isolation and connects over effect.But the tube structure that traditional contact box is bottom lock, contact box is contained on contact, the switch cubicle of large electric current in use, the fixed contact of contact box inside, Mume flower contact, produce a large amount of hot gas due to large electric current between copper bar by meeting, the heat produced due to contact can not distribute from contact box inside soon, thereby make the heat of gathering in contact box increasing, easily cause the contact oxidation, increase resistance, and then the larger heat of generation, cause insulation system to destroy, cause short circuit, useful life and the security performance of equipment have been reduced, affected to a certain extent the use of switch cubicle.。
The utility model content
For solving the problems of the technologies described above, the utility model, for the problem of prior art contact box weak heat-dissipating, provides the contact box that a kind of heat dispersion is good.
For achieving the above object, adopted following technical scheme:
The large electrical insulation contact box of a kind of band heat dissipation channel, comprise cylindrical shell, the bottom lock of described cylindrical shell, the cylindrical shell top has incoming line, on described cylindrical shell, be provided with and cylindrical shell line outlet connected vertically, described line outlet communicates with the inner chamber of cylindrical shell, it is characterized in that on cylinder lateral wall also being provided with heat dissipation channel, and heat dissipation channel is communicated with inner chamber and the cylindrical shell outside of cylindrical shell.Owing to being provided with heat dissipation channel on cylinder lateral wall, heat dissipation channel is communicated with inner chamber and the cylindrical shell outside of cylindrical shell, can discharge the hot-air of inner barrel, thereby reduces the temperature of contact box inner air.
During concrete enforcement, heat dissipation channel is positioned on the sidewall of the cylindrical shell relative with line outlet.
During concrete enforcement, the inside and outside wall of cylindrical shell is respectively equipped with the insulation cluster parachute, and the bottom of cylindrical shell is provided with inserts with threaded hole.The inside and outside wall of cylindrical shell is respectively equipped with the insulation cluster parachute, and the outer loose skirt of establishing can effectively prevent that arcing from occurring, can improve insulating properties, thereby improve the fail safe of circuit, and can increase the service life.
The design by the change mould with the large electrical insulation contact box of heat dissipation channel of the present utility model, increase a heat dissipation channel at the back side of contact box product, make the hot-air of contact box inside be dispersed into outside by radiating groove, dissipate hot gas, thereby reduce the air themperature of contact box inside, improve the environment for use of switch cubicle, improve the useful life of switch cubicle.The utility model design is ingenious, thereby can discharge the temperature of the hot-air reduction contact box inner air of contact box inside, and using method is identical with common contact box, does not affect other parameters that product is installed and used.
Beneficial effect: because the utility model cylinder lateral wall is provided with heat dissipation channel, heat dissipation channel is communicated with inner chamber and the cylindrical shell outside of cylindrical shell, thereby reduce the temperature of contact box inner air, there is good heat dispersion, the heat that contact can be produced sheds rapidly, keep contact in the works fine environment, thereby avoid short circuit accident to occur, improved switch cubicle overall performance and useful life.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, utility model is further illustrated.
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1, cylindrical shell 2, incoming line 3, bottom 4, line outlet 5, heat dissipation channel 6, insulation cluster parachute 7, inserts 8, screwed hole.
Embodiment
In Fig. 1, the large electrical insulation contact box of a kind of band heat dissipation channel, the cylindrical shell 1 that comprises poured with epoxy resin, bottom 3 sealings of cylindrical shell 1, top have incoming line 2, the inside and outside wall of cylindrical shell 1 is respectively equipped with insulation cluster parachute 6, the bottom 3 of cylindrical shell 1 is provided with threaded hole 8 inserts 7, on cylindrical shell 1, be provided with and cylindrical shell 1 line outlet 4 connected vertically, line outlet 4 communicates with the inner chamber of cylindrical shell 1, also be provided with heat dissipation channel 5 on cylindrical shell 1 sidewall, heat dissipation channel 1 is communicated with inner chamber and cylindrical shell 1 outside of cylindrical shell 1, and heat dissipation channel 5 is positioned on the sidewall of the cylindrical shell 1 relative with line outlet 4.Owing on cylindrical shell 1 sidewall, being provided with heat dissipation channel 5, heat dissipation channel 5 is communicated with inner chamber and the cylindrical shell outside of cylindrical shell 1, can discharge the hot-air of cylindrical shell 1 inside, thereby reduces the temperature of contact box inner air.
Claims (3)
