Description
Technical field
The utility model relates to a kind of radome for GIS electronic mutual inductor.
Background technology
At present, along with the development of electric power system, popularizing of intelligent substation, the use of electronic mutual inductor has more and more become a kind of trend, existing 110kV, 220kVGIS are very ripe by electronic mutual inductor technology, 500kVGIS has become a kind of inevitable outcome with the appearance of electronic mutual inductor and application, and the distribution that how to shield the non-uniform electric field of instrument transformer inside and improve electric field becomes problem demanding prompt solution.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, and a kind of radome for GIS electronic mutual inductor is provided, and the effect that it can play the inner non-uniform electric field of shielding instrument transformer, has improved instrument transformer insulating reliability and stability.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of radome for GIS electronic mutual inductor, comprise cover body, the middle part of cover body is provided with the shielding cavity of outwardly convex and its interior accommodating conductively-closed thing, cover body is provided with binding face in a side of shielding cavity, and cover body is provided with the adpting flange with connecting hole at the opposite side edge of shielding cavity.
Further, in order to improve external electrical field, the outside wall surface of described cover body is smooth outer wall face.
Further in order to realize the seamless applying to strengthen its shield effectiveness of radome and other equipment when fixing, ensure and tight type and reliability when other equipment connections, described binding face is positioned at the side direction of adpting flange.
Further, described cover body is circular ring structure, and the cross section of described shielding cavity is semicircular structure.
Further, described cover body is made of one piece by aluminium.
Adopted after technique scheme, the shielding cavity inner space of radome can shield the non-uniform electric field that the protrusions such as screw cause, outside can polish smooth and chamfering enough large, can play improve external electrical field distribute effect; Adpting flange place plane, in the outside of binding face, can realize the seamless applying of radome and other equipment when fixing; Adopt the 1060 aluminium entirety processing of 2mm, ensured mechanical strength; Compared with the radome of using with electronic mutual inductor with 110kV, 220kV GIS, the shield effectiveness of this structure is outstanding, and quality is light, simple in structure, has saved raw material, has improved working (machining) efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of the radome for GIS electronic mutual inductor of the present utility model;
Fig. 2 is the scheme of installation of the radome for GIS electronic mutual inductor of the present utility model.
Embodiment
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below.
As shown in Figure 1, a kind of radome for GIS electronic mutual inductor, comprise cover body 1, the middle part of cover body 1 is provided with the shielding cavity 1-1 of outwardly convex and its interior accommodating conductively-closed thing, cover body 1 is provided with binding face 1-2 in a side of shielding cavity 1-1, and cover body 1 is provided with the adpting flange 1-3 with connecting hole at the opposite side edge of shielding cavity 1-1.Connecting hole can be 12-16.
In order to improve external electrical field, the outside wall surface of cover body 1 is smooth outer wall face.
As shown in Figure 1, in order to realize the seamless applying to strengthen its shield effectiveness of radome and other equipment when fixing, ensure and tight type and reliability when other equipment connections, binding face 1-2 is positioned at the side direction of adpting flange 1-3.
Cover body 1 is circular ring structure, and the cross section of described shielding cavity 1-1 is semicircular structure.
Cover body 1 is made of one piece by aluminium, and cover body 1 processes by mould or spinning process.
As shown in Figure 2, when radome is used electronic mutual inductor for 500kV GIS, the adpting flange 1-3 of radome is connected by screw with fixed head 2, and fixed head 2 is connected by screw with coil box 3, is placed with coil 4 in coil box 3.Because the screw of fixed coil box 3 is positioned at radome inside, the non-uniform electric field conductively-closed cover shielding producing; Simultaneously the outside wall surface of radome is smooth and chamfering is enough large, plays very important effect for the Electric Field Distribution of improving outside instrument transformer internal shield cover.
Operation principle of the present utility model is as follows:
The shielding cavity 1-1 inner space of radome can shield the non-uniform electric field that the protrusions such as screw cause, outside can polish smooth and chamfering enough large, can play improve external electrical field distribute effect; Adpting flange 1-3 place plane, in the outside of binding face 1-2, can realize the seamless applying of radome and other equipment when fixing; Adopt the 1060 aluminium entirety processing of 2mm, ensured mechanical strength; Compared with the radome of using with electronic mutual inductor with 110kV, 220kV GIS, the shield effectiveness of this structure is outstanding, and quality is light, simple in structure, has saved raw material, has improved working (machining) efficiency.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect that the utility model is solved further describe; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
