Description
Technical field
The utility model relates to a kind of flexible direct current valve grading shield.
Background technology
Technology of HVDC based Voltage Source Converter also claims VSC-HVDC technology, it is a kind of VSC-HVDC technology based on voltage source converter (VSC), igbt (IGBT), it has can independent regulation gain merit and the advantage of reactive power, can to passive network power transmission, overcome the essential defect of traditional HVDC, the advantage of HVDC is expanded to power distribution network, has greatly widened the range of application of HVDC, had broad application prospects.
Along with the application of VSC-HVDC technology in electric power system, flexible direct current valve also arises at the historic moment.Flexible direct current valve is contacted by numerous module, the expansion of the cumulative of voltage and capacity can be realized, current ceiling voltage can reach 500kV, flexible direct current valve has become large-scale power primary equipment, therefore need to carry out high-voltage electromagnetic protection by the module, insulating part, structural member, optical cable, water pipe etc. of grading shield to flexible direct current valve inside, and difficulty when considering high-altitude installation, upkeep operation.Tradition grading shield size is large, mounting means is complicated, makes troubles, have much room for improvement to construction, maintenance.
Utility model content
The purpose of this utility model, is to provide a kind of ready-package grading shield, its have quick for installation, safeguard light feature, reduce the danger coefficient of work high above the ground.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of ready-package grading shield, comprise cover body, support, guide finger and fixed part, wherein, the bottom welding of cover body is in the side of support; Guide finger is welded on the opposite side bottom of support, for coordinating with the installing hole on bracket; The homonymy of fixed position guide finger on support, and fixed part is welded on the top of this side of support, and corresponding with the position of spot welding nut on bracket.
The bottom non-close of above-mentioned cover body, and the non-close place of support welding bottom cover body.
Above-mentioned guide finger comprises connector and shank, and described connector is L-type, and an one side is welded on the opposite side of support, and makes another side of connector be positioned at the bottom of support, and shank is fixed on the bottom of another side of described connector.
Fixation portions is U-shaped, and an one side is welded on the top with guide finger homonymy on support, and the position of another side spot welding nut on corresponding bracket offers fixing hole.
Above-mentioned support is vertically arranged.
After adopting such scheme; the utility model can be quick installed on bracket; all high voltage electric field is pressed for providing primary equipment; realize the electromagnetic protection of flexible direct current valve, the utility model considers mechanical strength and electromagnetic protection, can the Primary Component of protective valve inside and insulating part; reduce hardware point discharge; control office discharges water flat, improves the field strength distribution of valve body, and have quick for installation, safeguard the features such as light.

Embodiment
Below with reference to accompanying drawing, the technical solution of the utility model is described in detail.
As shown in Figure 3, the utility model provides a kind of ready-package grading shield, comprise cover body 201, support 202, guide finger 203 and fixed part 204, wherein, the bottom non-close of cover body 201, this side of support 202, to be connected to the side of support 202 bottom it, specifically can be welded on the non-close place bottom cover body 201, thus to play booster action to cover body 201 by cover body 201; Described support 202 is vertically arranged; Described guide finger 203 is welded on the opposite side bottom of support 202, play and guiding and the effect retrained are installed, described guide finger 203 comprises connector and shank, described connector is L-type, an one side is welded on the opposite side of support 202, and make another side of connector be positioned at the bottom of support 202, and shank is fixed on the bottom of another side of described connector; And fixed part 204 is positioned at the homonymy of guide finger 203 on support 202, and fixed part 204 is welded in the top of this side of support 202, for realizing, reinforcement of the present utility model is fixed, described fixed part 204 is U-shaped, an one side is welded on the top with guide finger 203 homonymy on support 202, and the position of another side spot welding nut 103 on corresponding bracket 102 offers fixing hole.
During use, first as shown in Figure 1, tilt the utility model ready-package grading shield 101 certain angle, by installing hole corresponding on guide finger 203 aligning bracket 102, then just push away by ready-package grading shield 101, now guide finger 203 inserts in installing hole naturally, forms related constraint; Then coordinate shown in Fig. 2, now fixed part 204 is corresponding with the position of spot welding nut 103 on bracket 102, uses screw assemblies 104 through described fixed part 204 and is fastened on the spot welding nut 103 of bracket 102, completing the installation of ready-package grading shield 101.Described ready-package grading shield 101 can provide primary equipment high-voltage electromagnetic to protect, and control integral device office and discharge water flat, play the object of protection electric equipment, structure is simple, quick for installation.When maintenance needs dismounting, only oppositely need implement by abovementioned steps, safeguard light.
Above embodiment is only and technological thought of the present utility model is described; protection range of the present utility model can not be limited with this; every technological thought according to the utility model proposes, any change that technical scheme basis is done, all falls within the utility model protection range.
