Abstract
The invention relates to the technical field of apparatuses for electrical equipment and particularly relates to a connecting device for an oil charge and drainage pipeline of a transformer and discloses an oil charge and drainage flange connector for a transformer. The oil charge and drainage flange connector for the transformer comprises a flange plate with an oil port at the center. A plurality of connecting holes which are uniformly distributed are further formed on the flange plate around the oil port for penetrating fixed bolts. The connecting holes are double bent long holes which are provided with two continuous arc-shaped bent parts in the length directions of the connecting holes, the two continuous arc-shaped bent parts are arranged reversely and are smoothly connected, the double bent long holes encircle the center of the flange plate in the length directions of the double bent long holes, and the width of the double bent long holes is matched with the size of the fixed bolts. The oil charge and drainage flange connector for the transformer provided by the invention is simple in structure, can be suitable for charging and draining oil for transformers of various models, needs not to be frequently replaced, and is simple in connecting operation, so that the connecting efficiency is improved, the mounting time is shortened, and various flange connectors are not equipped.
Description
Technical field
The present invention relates to fixture technology field used by power equipment, especially relate to transformer charge and discharge oil pipe line and connect dress
Put.
Background technology
Repair of Transformer needs frequent charge and discharge transformer oil, is connected main transformer fuel outlet valve flange and oil pipe with bump joint.
Because voltage device main transformer model is a lot, transformer model is different, and fuel outlet valve flange bore is not of uniform size, and screw centre distance is not yet
Identical to the greatest extent.Need to match corresponding bump joint with connecting line according to voltage device main transformer model during maintenance, increase
The workload of staff.
And, it is easy to situations such as bump joint occurs device to hole, pitch-row be not inadequate during manufacturing flange joint, need again
Perforating device to hole, wastes the substantial amounts of repair time, operating efficiency greatly reduces.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of transformer oil charging-discharging flange connection, and structure is simple, can
, using it is not necessary to frequent change, attended operation is simple, improves joint efficiency, shortens for the transformer oil charging-discharging adapting to Multiple Type
Set-up time, it is to avoid the outfit of multiple flange connection.
For solving above-mentioned technical problem, the technical solution used in the present invention is：Transformer oil charging-discharging flange connection, bag
The center of including is provided with the ring flange of hydraulic fluid port, and described ring flange is additionally provided with equally distributed multiple connecting hole around described hydraulic fluid port, uses
Penetrate in fixing bolt, described connecting hole is the tangent bend elongated hole being provided with two continuous arc-shaped curvature portion in its length direction, two
Individual continuous arc-shaped curvature portion is oppositely arranged and in smoothing junction, and described tangent bend elongated hole is in its length direction in described ring flange
The heart, the width of described tangent bend elongated hole and fixing bolt size match.
The distance of hole center to the described ring flange center at its two ends for the described tangent bend elongated hole is different.
Described connecting hole is four.
Described ring flange is communicated with the tubular diversion division of hydraulic fluid port in its side, and the end of described tubular diversion division is provided with outward
Screw thread, for being connected with oil pipeline.
Described tubular diversion division from described oil port to its end external screw thread at diameter taper into.
Described ring flange and tubular diversion division are stainless steel.
Have the beneficial effects that using produced by technique scheme：The company of transformer oil charging-discharging flange connection of the present invention
Connecing hole adopts elongated hole to design, and can make tangent bend elongated hole and main transformer fuel outlet valve flange connecting hole in ring flange by rotary flange disk
Axially realize rapid-aligning, double-bend design makes elongated hole have multiple continuous pitch-rows along its length, by rotary process
Blue disk can select the pitch-row mated from main transformer fuel outlet valve flange connecting hole it is thus possible to adapt to multiple different to a certain extent
The transformer of model is it is achieved that preferable versatility.Apply connector of the present invention can realize easily and fast filling with transformer
Drain the oil the connection of flange, effectively save the time of installation, improve operating efficiency, simplify outfit.

Specific embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
See Fig. 3 and Fig. 4, respectively illustrate the different embodiments of transformer oil charging-discharging flange connection of the present invention, wherein method
The structure of blue disk 1 is shown in Fig. 1 and Fig. 2 respectively.Ring flange 1 center is provided with hydraulic fluid port 3, ring flange 1 is additionally provided with around hydraulic fluid port 3 and uniformly divides
Four connecting holes of cloth, penetrate for fixing bolt, and connecting hole is to be provided with two continuous arc-shaped curvature portion in its length direction
Tangent bend elongated hole 2, two continuous arc-shaped curvature portion are oppositely arranged and in smoothing junction, and tangent bend elongated hole 2 is in its length direction cincture
Ring flange 1 center, the width of tangent bend elongated hole 2 is matched with fixing bolt size.
In Fig. 1, the distance at hole center to ring flange 1 center at its two ends for the tangent bend elongated hole 2 is identical, two continuous arcs
Bend radian, arc length size are identical, and the distance at its hole center to ring flange 1 center first increases and diminishes afterwards.
In Fig. 2, the distance at hole center to ring flange 1 center at its two ends for the tangent bend elongated hole 2 is different, tangent bend elongated hole 2 edge
Its length direction, the distance at its hole center to ring flange 1 center is as general as increase tendency.
During installation, tangent bend elongated hole 2 and main transformer fuel outlet valve flange connecting hole can be made in ring flange by rotary flange disk 1
1 axially realizes rapid-aligning, and double-bend design makes elongated hole have multiple continuous pitch-rows along its length, by rotary process
Blue disk 1 can select the pitch-row mated with main transformer fuel outlet valve flange connecting hole it is thus possible to adapt to a certain extent multiple not
The transformer of same model is it is achieved that preferable versatility.
For the ease of the connection of ring flange 1 and oil pipeline, the tubular that ring flange 1 is communicated with hydraulic fluid port 3 in its side is led
