Description
Technical field
The present invention relates to a kind of box-type substation, particularly a kind of box-type substation housing with electro-magnetic screen function.
Background technology
Box-type substation is a kind of high voltage switchgear, distribution transformer and low-voltage distribution equipment; Line up indoor, the outdoor close-coupled controller switching equipment of prefabrication of one by certain connection plan; Being about to functions such as high powered, transformer step-down, low-voltage distribution organically combines; Be installed in a protection against the tide, antirust, dustproof, protection against rodents, fire prevention, antitheft, heat insulation, totally-enclosed, movably in the casing, electromechanical integration, totally-enclosed operation; Being specially adapted to city net construction and upgrading, is a kind of brand-new transformer station that after civil engineering transformer station, emerges.
Box-type substation is applicable to residential quarters, the public change in city, bustling downtown area, construction power supply etc., and the user can select box change according to different service conditions, load level.Box-type substation has developed very rapidly since coming out, and has accounted for 70% of distribution transformer in European developed country, and the U.S. has accounted for 90%.The develop rapidly of Chinese city modernization construction, the continual renovation transformation of urban power distribution network will be widely used.
The cabinet shell material of box-type substation is generally metal materials such as general steel plate, aluminium sheet, corrosion resistant plate and color steel at present; Though metal material itself has the certain electromagnetic function of shielding; But owing to do not design shielding construction on the present box for box-type transformer substation structure, so it does not possess complete electro-magnetic screen function.
Along with development of technology, the casing of metal current material is substituted by nonmetal GRC composite material just gradually, and the material in the casing is except that underframe is steel, and all the other are progressively non-metallic like compartment plate, door etc.Because the casing of nonmetal GRC material manufacture has multiple advantage; And can be by like the urban human trade, under the green belt, overpass, local installations such as biotope and scenic spot; Outward appearance can be mated with environment facies, again because floor space is less, has therefore obtained application more and more widely.
But also there is certain shortcoming in this GRC material box for box-type transformer substation, because what install in the box-type substation is electric equipment such as transformer, these equipment tend to produce a large amount of electromagnetic radiation in running.Work as this box-type substation like this and be installed in occasions such as residential quarters, the public change in city, bustling downtown area, the radiation that electric equipment produces just might be to people's the healthy adverse influence that causes; , this box-type substation then might the normal operation of other electric equipments be impacted near being installed in other electric equipments; As box-type substation be installed in magnetic suspension train rail around; The electromagnetic radiation that then electric equipment produces in the box-type substation might impact the normal operation of magnetic suspension train, even security incident might occur.Equally, the electric equipment in the transformer station box also receives the influence of external electromagnetic radiation easily, so also might the normal operation of electric equipment in the transformer station box be impacted.
Summary of the invention
To the deficiency of above-mentioned prior art, the technical problem that the present invention will solve provides a kind of box-type substation housing with electro-magnetic screen function.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of box-type substation housing with electro-magnetic screen function, it comprises a steel underframe, said steel underframe is provided with a casing; The top of said casing is provided with cover plate; Have door on the front side board of said casing, said casing adopts the GRC material, is equipped with the metallic shield net in the side plate of said casing and the said cover plate; The top of said side plate inner metal shield net is connected with the interior metallic shield net of said cover plate; The bottom of said side plate inner metal shield net is connected with said steel underframe, and the metallic shield net in the said casing adjacent side plates connects mutually, and the metallic object on the said casing all is electrically connected with said gauze screen and ground connection.
Preferably, be provided with metallic framework in the side plate of said casing and the cover plate, said metallic shield net is fixed on the said metallic framework.
Preferably, said metallic shield net and said metallic framework welding.
Preferably, the side plate of said casing is provided with the ventilation hole shutter of steel.
Preferably, be covered with steel plate on the said steel underframe, the bottom of said side plate inner metal shield net is connected with said steel plate.
Preferably, have steel door on the side plate of said casing, said steel door and said steel underframe, metallic shield net electrical communication.
Technique scheme has following beneficial effect: be equipped with the metallic shield net in the side plate of this box for box-type transformer substation and the cover plate; And the adjacent metal gauze screen interconnects; The bottom of box side metallic shield net is connected with the steel underframe; Therefore the metallic shield net just forms the shielding construction of a sealing; Be positioned at the just effectively conductively-closed of electromagnetic radiation of the electric equipment generation of box for box-type transformer substation like this, the casing outside does not almost have electromagnetic radiation in the power station, so just can effectively guarantee personnel's the healthy or safe operation of electric equipment on every side on every side; The adverse effect that simultaneously also can avoid the external electromagnetic radiation that box-type substation internal electric equipment is caused guarantees that box-type substation internal electric equipment normally moves.
Be installed on the various box-type substation products of residential quarter at present; People can produce electromagnetic radiation when generally worrying its operation and damage the healthy of people; As adopt patent of the present invention to have the nonmetal GRC casing of electro-magnetic screen function; Then electromagnetic radiation can effectively be masked, and can reduce industrial noise simultaneously, and this box power transformation product just can become and be above reproach like this.
