Abstract
The invention discloses a low-magnetism fixing bottom plate for wall penetrating casing pipes. The low-magnetism fixing bottom plate comprises a bottom plate body which can be fixedly installed in a wall and used for fixing the wall penetrating casing pipes. The bottom plate body is composed of a whole rectangular low-magnetism steel plate. Three holes for the wall penetrating casing pipes to be inserted and connected therein are formed in the surface of the bottom plate body in the longitudinal direction, and the circle centers of the three holes are located in the same straight line. At least three screw holes are evenly distributed in the periphery of each hole, and the screw holes are provided with bolts used for fixing the wall penetrating casing pipes. Three bolts used for connecting shells of the wall penetrating casing pipes to the ground are welded below the three holes respectively. Four screw holes are evenly distributed in the periphery of each of the three holes. The holes are round holes matched with the wall penetrating casing pipes, and positioning concave grooves are symmetrically formed in the upper sides and the lower sides of the round holes. A rectangular slot used for welding of a bottom plate grounding flat iron is formed in the lower left side of the bottom plate body. The low-magnetism fixing bottom plate has the beneficial effects that the installation structure is simple and firm, use is convenient and reliable, the use temperature can be effectively lowered, and safety operation of a power grid is ensured.
Description
Technical field
The present invention relates to a kind of low magnetic fixing bottom-plate of wall bushing, belong to electric power system high pressure power transmission and distribution technical field.
Background technique
In recent years along with the high speed development of society, the commercial power of enterprise and residential electricity consumption straight line rose, and made the main transformer capacity of original design can not meet workload demand, must carry out increase-volume.Therefore, annual summer, especially in grid company " summer peak meeting " therebetween, when customer charge increases, main transformer is exerted oneself greatly, main transformer low voltage side electric current increases thereupon, the wall bushing fixing bottom-plate of main transformer low voltage side is made greatly to increase and cause base plate heating problem especially severe because of the eddy current that electromagnetic induction produces, add the ambient temperature of hot heat in summer, base plate is generated heat add fuel to the flames especially, when ambient temperature is at 35 degree, main transformer low voltage side (10KV) load current is when about 2200A, what its temperature was the most serious even can up to 155 degrees Celsius, electric power system main transformer low voltage side electric pressure is as 110, 35, 10KV wall bushing used is essentially composite sheath dry type wall bushing, its insulating material is generally vulcanizing silicone rubber, its sleeve pipe suitable environment temperature is-40 degree-+40 degree, exceed temperature range, vulcanizing silicone rubber is easily aging, when temperature over-limit condition 150 degree, easy generation punctures, there is ground connection, the security incidents such as short circuit, seriously jeopardize grid equipment and personal security, simultaneously, base plate also limit the actual power load of main transformer, have influence on power grid security and main transformer is exerted oneself, tremendous influence is created to the electricity consumption reliability of user, in addition, also the electric energy conversion that makes of the base plate of heating is that heat energy is allowed expense in vain and falls.But at present, in whole electric power system, also not for reasonable, perfect process, the arrangement and method for construction of this problem, there is no the example that actual verification contrasts yet.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provide a kind of mounting structure simple, firmly, easy to use and reliable, the magnetic field that can effectively reduce due to wall bushing surrounding alternation produces the electric energy loss that eddy current causes; Effectively serviceability temperature be can reduce, the inlet wire of electric power netting safe running and the low magnetic fixing bottom-plate of outlet wall bushing ensured.
The object of the invention is to have come by following technical solution, a kind of low magnetic fixing bottom-plate of wall bushing, it comprises one piece and can be fixedly mounted in body of wall, for the base plate of fixing wall bushing, described base plate is that a monoblock rectangle low magnetic steel plate is formed, three holes for wall bushing grafting are longitudinally offered on the surface of this base plate, and the center of circle of three holes is on same straight line, each hole surrounding is evenly distributed with at least three screw holes, it is configured with the bolt for fixing wall bushing; One is respectively welded with for connecting the bolt of wall bushing rack earth below described three holes.
Preferred as one: three described hole surroundings are evenly distributed with four screw holes, and described hole is the circular hole adapted with wall bushing, and the symmetry up and down of circular hole offers locating notches make groove; The left bottom of described base plate offers one for welding the rectangular slotted eye of band iron chassis ground; Described base plate surrounding is provided with for carrying out with the angle steel be embedded on body of wall the welding edge that is welded and fixed.
The invention belongs to and the one of prior art is improved, it is simple, firm that it has mounting structure, easy to use and reliable, effectively can reduce serviceability temperature and ensure electric power netting safe running, the magnetic field of simultaneously having saved due to wall bushing surrounding alternation produces the features such as the electric energy loss that causes of eddy current.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1, the low magnetic fixing bottom-plate of a kind of wall bushing of the present invention, it comprises one piece and can be fixedly mounted in body of wall, for the base plate 1 of fixing wall bushing, described base plate 1 is that a monoblock rectangle low magnetic steel plate is formed, as selected 20MN23AIV low magnetic steel plate, three holes 2 for wall bushing grafting are longitudinally offered on the surface of this base plate 1, and the center of circle of three holes 2 is on same straight line, especially in central line; Each hole 2 surrounding is evenly distributed with at least three screw holes 3, it is configured with the bolt for fixing wall bushing; One is respectively welded with for connecting the bolt 4 of wall bushing rack earth below described three holes 2.
Shown in figure, three hole 2 surroundings of the present invention are evenly distributed with four screw holes 3, and described hole 2 is the circular hole adapted with wall bushing, and the symmetry up and down of circular hole offers locating notches make groove 5; The left bottom of described base plate 1 offers one for welding the rectangular slotted eye 6 of band iron chassis ground; Described base plate 1 surrounding is provided with for carrying out with the angle steel be embedded on body of wall the welding edge that is welded and fixed.
