Abstract
The utility model provides a kind of noise reduction box-type substation, and comprise casing and the electric equipment being installed on box inside, casing comprises base, is installed on the shaped steel forming framework above base and the sheet material be installed between each shaped steel; Sheet material inserts in the groove of shaped steel both sides, is fixedly connected with shaped steel column by securing member; Sheet material comprises color steel layer and sound absorbing layer.By arranging cavity and sound absorbing layer inside color steel, the noise of the effectively equipment generation of isolation transformer station inside, reduces the noise pollution to surrounding environment.
Description
Technical field
The utility model relates to transformer station's building structure field, particularly relates to a kind of box-type substation.
Background technology
Box-type substation is a kind of high voltage switchgear, distribution transformer and low-voltage distribution equipment, by indoor, the outdoor close-coupled controller switching equipment of certain connection plan row's all-in-one-piece prefabrication, organically combine by functions such as high powered, transformer pressure-reducing, low-voltage distributions, be arranged in a protection against the tide, antirust, dust-proof, protection against rodents, fire prevention, antitheft, heat insulation, totally-enclosed, moveable steel construction casing, electromechanical integration, totally-enclosed operation, be specially adapted to urban network construction and upgradation, a kind of brand-new transformer station emerged after Shi Ji civil engineering transformer station.
Because inner city land used is nervous, transformer substation in city periphery often has residential building building, then the propagation effect that produces surrounding enviroment of the running noises (comprising the electromagnetic noise of transformer and the noise of cooling, air discharging equipment) of transformer station, easily causes environment contradiction.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of box-type substation, can effectively pollute by less noise.
In order to solve the problem, the utility model provides a kind of noise reduction box-type substation, and comprise casing and the electric equipment being installed on box inside, described casing comprises base, is installed on the shaped steel forming framework above base and the sheet material be installed between each shaped steel; Described sheet material inserts in the groove of shaped steel both sides, is fixedly connected with shaped steel column by securing member; Described sheet material comprises color steel layer and sound absorbing layer.
Preferably, described color steel layer comprises inside and outside two-layer, and described sound absorbing layer is arranged between two-layer color steel.
Preferably, between described sound absorbing layer and internal layer color steel, bar shaped cavity is set.The noise that box inside electric equipment transmits can effectively effectively absorb by cavity.
Preferably, described sound absorbing layer is asbestos and aluminium silicate wool mixture.Asbestos have good tensile strength and good thermal insulation and anticorrosive property, and aluminium silicate wool has excellent thermal stability, chemical stability and sound absorption properties.
The beneficial effects of the utility model are: by arranging cavity and sound absorbing layer inside color steel, and the noise of the effectively equipment generation of isolation transformer station inside, reduces the noise pollution to surrounding environment.

Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, following embodiment should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.
See Fig. 1, the noise reduction box-type substation of the present embodiment, comprise casing and the electric equipment being installed on box inside, casing comprises base 1, is installed on the shaped steel 2 forming framework above base and the sheet material 3 be installed between each shaped steel.
See Fig. 2, sheet material 3 comprises internal layer color steel 31, sound absorbing layer 32 and outer color steel 33.Bar shaped cavity 4 is set between sound absorbing layer 32 and internal layer color steel 31.The noise that box inside electric equipment transmits can effectively effectively absorb by cavity 4.Sound absorbing layer 32 is asbestos and aluminium silicate wool mixture.Asbestos have good tensile strength and good thermal insulation and anticorrosive property, and aluminium silicate wool has excellent thermal stability, chemical stability and sound absorption properties.
See Fig. 3, sheet material 3 inserts in the groove of shaped steel 2 both sides, is fixedly connected with shaped steel 2 by securing member.
By arranging cavity and sound absorbing layer inside color steel, the noise of the effectively equipment generation of isolation transformer station inside, reduces the noise pollution to surrounding environment.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned execution mode, also comprises the technical scheme be made up of above technical characteristic combination in any.
