Description
Technical field：
The invention belongs to design of transformer manufacturing technology field, and in particular to a kind of draw bail of value side bushing afterbody.
Background technology：
Recently as developing rapidly for China's extra-high voltage direct-current transmission engineering, to transmission line capability and transmission distance and defeated
Electric economy proposes requirement higher, current ± 800kV voltage levels direct current engineerings, has in extra-high voltage DC transmission system
Have the advantages that good economy performance, engineering reliability are high, a period of time will be the mains voltage grade of China's DC transmission system from now on,
Therefore in order that value side bushing afterbody is installed and operation is easier conveniently, there is provided a kind of draw bail of value side bushing afterbody.
The content of the invention：
It is an object of the invention to provide a kind of draw bail of value side bushing afterbody.
The present invention adopts the following technical scheme that to realize：
A kind of draw bail of value side bushing afterbody, including conical shield pipe, coupling sleeve and value side bushing；Wherein,
It is provided with support on the inside of conical shield pipe, coupling sleeve is used to be set in one end circumference for being connected with conical shield pipe
Connecting plate is equipped with, coupling sleeve one end is connected on the support on the inside of conical shield pipe by connecting plate, and coupling sleeve is used for and cone
One end that shape shielded-plate tube is connected is connected with valve side lead by connector lug, and value side bushing is inserted into the other end of coupling sleeve.
Further improvement of the invention is that the other end that coupling sleeve is used to be connected with conical shield pipe is polyhedron knot
Structure, can be connected with multiple connector lugs, and each connector lug is respectively connected with valve side lead.
Further improvement of the invention is that each connector lug is connected by screw the polyhedron plane in coupling sleeve lower end
On, the other end is colded pressing and is connected to valve side lead.
Further improvement of the invention is, also including on the outside of coupling sleeve and equal with what conical shield pipe was connected
Pressure ball.
Further improvement of the invention is that the supporting leg of L-type, the inner side of conical shield pipe are provided with the inside of the voltage equalizing ball
Threaded block is additionally provided with, voltage equalizing ball is connected to the threaded block on the inside of conical shield pipe by supporting leg.
The present invention has the advantage that：
Be fixed on coupling sleeve on the support by the welding support on valve side shield pipe by the present invention, fixed preceding by connection
Set one end connects in advance with valve side lead, then is fixed on support, installs voltage equalizing ball again afterwards, i.e. coupling sleeve installation is not pressed
The influence of ball position, the pull-out conical shield pipe for trying one's best short by valve side lead is outer to be pried with coupling sleeve, is reduced when lead retracts
Difficulty, when last value side bushing is installed, sleeve pipe afterbody is inserted directly into the coupling sleeve other end, can directly be filled without opening hand hole
Upper value side bushing, reduces possible breakdown point hidden danger.
The draw bail of the value side bushing afterbody that the present invention is provided, is more simply more beneficial for value side bushing installation, effectively
Whole installation operation program is reduced, the set-up time is saved, with preferable economic benefit and social benefit, makes the peace of value side bushing
Dress be easier, it is faster.
