Part is typically located at the edge of converter valve submodule.Existing left comer shielding case is all to be fixed on by supporting item in valve tower,
Though having fastness, when maintenance replacement is carried out to converter valve submodule, left comer shielding case need to be dismantled, cumbersome complexity,
Although what is had can realize the replacement of converter valve submodule, due to left comer shielding case by being moved to left comer shielding case
Volume is big, quality weight, lacks support device in moving process, and there are larger security risk, and the notch of supporting item is mostly
Rectangular slits, easily produce the phenomenon of point discharge.
The content of the invention
The utility model aim is to provide a kind of left comer shielding easy to disassemble, bending strength is big, anti-voltage ageing is good
Shade assembly.
In order to realize above-mentioned technical purpose, the technical solution that the utility model left comer shield assemblies use for：
A kind of left comer shield assemblies, including housing, insulated support at housing short side and grow arranged on housing
Connector at side, the end face of the housing long edge position are equipped with multiple crossbeams, and the beam surface has been bolted to connection
For connecting the connector of converter valve, the connector includes short stent, and the short stent side is equipped with L-shaped long stent, described
The end of long stent is equipped with multiple insulated bolts, and the insulated support includes F shape supporting racks, the L-shaped opening of support frame as described above
Place is equipped with trapezoidal supporting table, and the end of the trapezoidal supporting table uses arc transition, is equipped with the U-shaped opening of support frame as described above perpendicular
The yi word pattern supporting beam directly placed.
Preferably, the housing is L-shaped for cross section, and end uses the groove-like case of arc transition.By by housing
L-shaped is arranged to, it is met the installation requirement of converter valve corner, meanwhile, arc transition is carried out to end, tip is avoided the occurrence of and puts
The phenomenon of electricity.
Preferably, the insulated support is fixedly connected with the casing by bolt is integrated.
Preferably, the length of the connector is more than the length of the crossbeam.The length of connector is set greater than horizontal stroke
The length of beam, is connected so that it is guaranteed that connector is consolidated with housing, meanwhile, the compactness that lifting housing is connected with converter valve.
Preferably, the trapezoidal supporting table both sides are equipped with connection bolt.By set connect bolt, make insulated support with
Converter valve consolidates connection.
Preferably, the supporting beam both sides are equipped with connection bolt.
Compared with prior art, the beneficial effects of the utility model are：
The utility model makes left comer shield assemblies change with converter valve tie point by setting multiple connectors,
So as to which opposite converter valve valve tower makes displacement, and then easy to the replacement of converter valve submodule, avoid and be typically designed middle change
Valve submodule is flowed, need to first dismantle the complicated processes of left comer shielding case；Insulated support is utilized at the same time, not only strengthens left comer shielding
Cover and the connectivity of converter valve, and by handling the circular arc of trapezoidal supporting table end, lift overall insulating properties and shielding
Property, it ensure that overall anti-voltage ageing.

Embodiment
With reference to the accompanying drawings and detailed description, the utility model is furtherd elucidate, it should be understood that these embodiments are only
For illustrating the utility model rather than limitation the scope of the utility model, after the utility model has been read, this area
Modification of the technical staff to the various equivalent forms of the utility model falls within the application appended claims limited range.
As shown in Figure 1 to Figure 2, a kind of left comer shield assemblies, including housing 1, the insulating supporting at 1 short side of housing
Part 2 and the connector 3 arranged on 1 long edge position of housing, the housing 1 is L-shaped for cross section, and end uses the groove of arc transition
Shape case, the end face of 1 long edge position of housing are equipped with multiple crossbeams 4, and 4 surface of crossbeam, which is bolted to connection, to be useful for
The connector 3 of converter valve is connected, the length of the connector 3 is more than the length of the crossbeam 4, and the connector 3 includes short branch
Frame 5, short 5 side of stent are equipped with L-shaped long stent 6, and the end of the long stent 6 is equipped with multiple insulated bolts 7, the insulation
Supporting item 2 includes F shapes supporting rack 8, and the L-shaped opening of support frame as described above 8 is equipped with trapezoidal supporting table 9, the trapezoidal supporting table 9
End uses arc transition, and trapezoidal 9 both sides of supporting table are equipped with connection bolt 11, are equipped with the U-shaped opening of support frame as described above 8
