Description
Technical field
The present invention relates to a kind of access path, belong to electrical equipment technical field.
Background technology
Converter valve tower is the component units of high-voltage large-capacity DC converter, is a kind of large scale electrical power unit.Single valve
Tower is a double valve or quadruple valve, is generally made up of multiple valve layer stacked on top of one another and top radome and bottom radome.Cause
Valve tower height degree and voltage level are high, and current valve tower is all to be suspended to using sus-pension in the valve Room, and the valve tower bottom road clearance is big,
And the distance between valve layer is also larger inside valve tower.Therefore, later stage repair and maintenance should be taken into full account in converter valve Deethanizer design
Convenience and security.
The Maintenance and Repair of current converter valve tower mainly have two ways, and one kind is, without access path inside valve tower, to utilize
Operation maintenance personnel is increased to the position that valve tower needs to overhaul by lift truck, and the maintenance of valve tower ancillary equipment is completed on lift truck, valve
The maintenance of tower internal unit needs operation maintenance personnel to be transferred to completion in valve tower from lift truck, because not special maintenance is logical
Road, operation maintenance personnel does not have good foothold in valve tower, and the maintenance of different valve layer also needs to come between lift truck and valve tower
Revolution is moved, and is not only not easy to maintenance, and security can not also ensure；Another is that access path is provided with inside valve tower, in inspection
The end for repairing passage is provided with window, and insulating ladder has also been fixedly disposed on the side of window, and insulating ladder is arranged on valve tower
On the metal busbar at edge, maintainer can pass through the window of access path end by insulating ladder, realize up and down not
Moved between valve layer access path, substantially increase the convenience of operation maintenance personnel work, but insulating ladder is to be fixedly mounted
On valve tower, need to take into full account electrical Interference problem of the cat ladder to valve tower in valve Deethanizer design, can for example shorten above and below valve layer
Between creep age distance；Not converter valve runs necessary part to cat ladder in itself, is fixedly mounted on valve tower, can also increase
Long-term heavy burden when valve tower is run；In addition, in order to not influence maintainer to be worked on inspection platform, and convenient fixation, inspection
Repair cat ladder to be all integrally fixed on the interlayer metal busbar at valve tower edge, when can so cause the operation maintenance personnel to move on cat ladder, directly
Junction is to high-altitude, and with fear at heart, there is also security risk.
The content of the invention
It is an object of the invention to overcome the defect that prior art is present, a kind of maintenance of power equipment internal proprietary is proposed
Passage.
The present invention is adopted the following technical scheme that：A kind of access path, it is characterised in that including cat ladder, multiple inspection platforms,
It is provided with window, the inspection platform and also sets up on the parallel distribution above and below of multiple inspection platforms, the inspection platform
There is the slidably cover plate for covering the window, two adjacent inspection platforms are connected by the cat ladder.
Preferably, inspection platform includes girder, crossbeam, and girder is mutually fixedly connected with crossbeam, is set between adjacent crossbeam
There is crosspiece.
Preferably, slidably the both sides of cover plate are provided with two tracks, and track is respectively arranged in the both sides of inspection platform, rail
The two ends in road are provided with alignment pin, for limiting the sliding scale that slidably cover plate is in orbit；Slidably also set on cover plate
Fixture is equipped with, for being fixed when slidably cover plate slides into specified location.
Preferably, slidably the area of cover plate in the horizontal direction is more than or equal to the area of window in the horizontal direction.
Preferably, cat ladder includes cross bar, expansion link, and cross bar is fixedly connected with expansion link；Hook is provided with the top of cat ladder,
The side of window is placed in, for the upper end of cat ladder is fixed.
Preferably, the window on multiple inspection platforms is opened in identical position or different positions.
Preferably, inspection platform is made of flame-resistant insulation material.
The beneficial effect that the present invention is reached：（1）Access path is provided with inside converter valve tower, facilitates the maintenance in later stage
Safeguard；（2）When operation maintenance personnel is moved using the window on cat ladder and inspection platform between different valve layer, all operations are in valve tower
Portion is completed, without in face of high-altitude, no fear is safer；（3）Maintenance cat ladder is carried with, after maintenance is finished, direct band
Lower valve tower, does not interfere with the layer insulation of valve tower, will not increase the long-term heavy burden of valve tower in operation yet.
