Description
Technical field
The present invention relates to transformer technology field, particularly to the manhole device of a kind of 110kV power transformer.
Background technology
In prior art, for 110kV power transformer, staff is when making or overhaul, very inconvenient, does not allows
Easily observe the inner case of oil tank of transformer, it is impossible to be rapidly completed maintenance or make, thus add making or the cost of overhaul, fall
Low production efficiency.
Summary of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide the manhole device of a kind of 110kV power transformer,
Operator or probe is facilitated to enter oil tank of transformer by manhole, to realize making or the maintenance of the fuel tank of transformator.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, the present invention is achieved through the following technical solutions: a kind of
The manhole device of 110kV power transformer, including manhole flange, cover plate for manhole and sealing gasket, power transformer has fuel tank, institute
Stating manhole flange to be welded on the tank wall of fuel tank, described cover plate for manhole lid is located on described manhole flange, described cover plate for manhole with
Being provided with sealing gasket between manhole flange, cover plate for manhole is connected with described manhole flange by fixation kit, and this fixation kit includes
Fixing bolt, plain washer and spring washer, fixing screw bolt passes spring washer, plain washer, cover plate for manhole and manhole flange,
Cover plate for manhole and manhole flange being fixed together, described cover plate for manhole is provided with handle.
Further, the quantity of described fixation kit is multiple, the plurality of fixation kit along the circumference of cover plate for manhole in all
Even distribution.
The invention has the beneficial effects as follows: be welded with manhole flange on the fuel tank tank wall in the present invention, manhole flange upper cover sets
There are cover plate for manhole, cover plate for manhole to be connected by fixation kit with manhole flange, thus when transformator makes or overhauls, can twist
The most fixing bolt, opens cover plate for manhole, and staff by the fuel tank of manhole flange turnover transformator, or can use probe
Enter the fuel tank of transformator, to observe the inner case of the fuel tank of transformator, it is simple to realize transformator and make or maintenance.The present invention
Structure eliminate one section lengthen pipe, more convenient people pass in and out, reduce processing cost, facilitate operation, improve production
Efficiency, optimizes the function of manhole.It addition, manhole flange is arranged on the tank wall of fuel tank by the way of welding, so that
Inlet manhole is closer to fuel tank, and convenient staff passes in and out.It is provided with sealing gasket between cover plate for manhole and manhole flange, makes
Transformator properly functioning time, it is ensured that the sealing state of manhole.Fixation kit has spring washer and plain washer, passes through
Spring washer, plain washer and the cooperation of fixing bolt, so that more may be used fixing connection the between cover plate for manhole with manhole flange
Lean on.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of cover plate for manhole.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
As depicted in figs. 1 and 2, the manhole device of a kind of 110kV power transformer, including manhole flange 1, cover plate for manhole 2
With sealing gasket 3, power transformer has fuel tank, and described manhole flange 1 is welded on the tank wall 4 of fuel tank, and described cover plate for manhole 2 covers
Being located on described manhole flange 1, be provided with sealing gasket 3 between described cover plate for manhole 2 and manhole flange 1, cover plate for manhole 2 is by fixing
Assembly is connected with described manhole flange 1, and this fixation kit includes fixing bolt 5, plain washer 6 and spring washer 7, fixing bolt 5
Sequentially pass through spring washer 7, plain washer 6, cover plate for manhole 2 and manhole flange 1, by cover plate for manhole 2 and the fixing connection of manhole flange 1
Together, described cover plate for manhole 2 is additionally provided with handle 21.
Furtherly, the quantity of described fixation kit is multiple, the plurality of fixation kit along the circumference of cover plate for manhole 2 in all
Even distribution.
Manhole flange 1 in the present invention is welded on the manhole of tank wall 4 of oil tank of transformer, and manhole flange 1 is covered with
Cover plate for manhole 2, cover plate for manhole 2 is connected by fixation kit with manhole flange 1.When transformator is properly functioning, cover plate for manhole 2 covers
On manhole flange 1, manhole is in closed state.When transformator makes or overhauls, fixing bolt 5 can be backed out, open people
Blind patch 2, staff can be passed in and out the fuel tank of transformator, or use probe to enter the oil of transformator by manhole flange 1
Case, to observe the inner case of the fuel tank of transformator, it is simple to realizes transformator and makes or maintenance.The structure of the present invention eliminates one
