Abstract
The utility model discloses a kind of new construction all insulation station local coordinate frames, the transformer includes tank body of oil tank, case lid, oil conservater and high pressure dust cover, high-pressure side one plug-in type cable head casing tube is drawn from traditional case lid to become drawing from side wall, not only increase external insulation of transformer, water resistance, in humidity, overcast and rainy and thunder and lightning weather is safer when running, reliably, and for low capacity stations of the 35kV or more with dust cover becomes, side wall extraction tube can be more convenient downlink cable routing, avoid because dust cover space is limited cause cable that can not slightly be bent excessively due to influence practice of construction, under the premise of ensuring the convenient and attended operation personnel safety of construction, the electric clearance between casing can also substantially be reduced, especially suitable for high ground, High aititude, the electric operating area of downward cabling.
Description
Technical field
The utility model is related to power equipment transformer, specially a kind of low capacity all insulation station local coordinate frame.
Background technology
Many power stations domestic at present and construction site need 35kV grades of station local coordinate frames, its main feature is that：Capacity is small, volume
Small, high-low voltage grade differs apparent, in some special occasions（Pollute height, dust height, bad weather etc.）It must be in high-low pressure
Casing side is capped dust cover, and the true procelain bushing of 35kV grades of tradition or more is generally located on right over babinet, because climbing
Away from covering dust cover is too high to, although integrated plug-in elbow-type head casing tube energy covering dust cover is changed into, but often in reality
Because of 35kV grades of cables in the construction of border（Especially armored cable）Bending radius is too big and can not be bent and draw in dust cover, pacifies
It fills inconvenient, proposes the utility model thus, can perfectly solve problem above.
Invention content
To solve the above problem of the existing technology, convenient for live practice of construction, transformer installation space is rationally utilized,
The utility model provides a kind of all insulation station local coordinate frame of brand new, and the technical solution taken is：
A kind of low capacity all insulation station local coordinate frame, it includes fuel tank, case lid, the bushing of integrated plug-in, high pressure
Bushing lifting seat, high pressure dust cover and oil conservater are provided with transformer in fuel tank, and opening bushing in tank body of oil tank side increases
Bore installs bushing and increases seat, and the bushing of integrated plug-in, which is mounted on side wall bushing, to be increased on seat, is drawn
Vertically downward, bushing is covered on inside to end by body side setting cell type high pressure dust cover, is not only convenient for constructing in this way
When connecting cable, it is ensured that effect of the dust cover in transformer actual motion；The high pressing sleeve of original that will be vacated above case lid
Pipe position ensures the installation that transformer is saved in the case where transformer accessory is complete to install oil conservater and gas relay
Space；Oil conservater can guarantee that in transformer respiratory, oil completely cuts off completely with air, delay the aging rate of oil.
The bushing is T shapes, and top increases seat connecting pin outgoing cable with bushing and connect with transformer, separately
One end is outgoing cable head end downward.
The characteristics of the utility model, is to draw high-pressure side one plug-in type cable head casing tube into change from traditional case lid
To be drawn from side wall, external insulation of transformer, water resistance are not only increased, is sealed when moist, overcast and rainy and thunder and lightning weather is run
Property it is more preferable, whole device is more safe and reliable, and for low capacity stations of the 35kV or more with dust cover becomes, side
Wall extraction tube can be more convenient downlink cable routing, avoid because dust cover space is limited cause cable that can not slightly be bent excessively due to influence
Practice of construction can also substantially reduce the electricity between casing under the premise of ensuring the convenient and attended operation personnel safety of construction
Gas gap, the electric operating area especially suitable for high ground, High aititude, downward cabling；It is used with traditional High aititude station that is applied to
Transformer is compared, since casing size and oil conservater extension elongation significantly reduce so that package size is small and exquisite, user-friendly
And installation, the utility model have that simple structure, practicability are high, manufacturing cost is low, performance safety is reliable, later maintenance side
Just the features such as.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is Fig. 1 side structure schematic views；
Fig. 3 is the overlooking structure diagram of Fig. 1.
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
As shown in the picture：A kind of low capacity all insulation station local coordinate frame, it includes fuel tank 1, case lid 2, integrated plug-in height
Pressing sleeve pipe 3, bushing increase seat 4, high pressure dust cover 5, oil conservater 6, transformer are provided in fuel tank 1, in 1 case-side of fuel tank
Face opens bushing and increases bore installation bushing raising seat 4, and the bushing 3 of integrated plug-in is mounted on side wall high pressure
On bushing lifting seat 4, vertically downward, 1 side of babinet setting cell type high pressure dust cover 5 covers on bushing 3 to outgoing cable head
Inside is not only convenient for connecting cable when construction, it is ensured that effect of the dust cover in transformer actual motion in this way；Case lid
2 tops to install oil conservater 6 and gas relay, ensure the former bushing position vacated complete in transformer accessory
In the case of save transformer installation space；Oil conservater 6 can guarantee that in transformer respiratory, oil completely cuts off completely with air,
Delay the aging rate of oil.
The bushing is T shapes, and top increases seat connecting pin outgoing cable with bushing and connect with transformer, separately
One end is outgoing cable head end downward.
The bushing increases seat and is located at fuel tank sidewall, and high-pressure side one pluggable cable head sleeve structure is generally
The down-lead base of fuel tank internal, coil device body that traditional small capacity transformer is determined because of its use scope and inner wall of oil tank away from
Close, this produces prodigious trouble for the installation of high-voltage lead of transformer or even when transformer puts into operation will produce
The dangerous situations such as unnecessary electric leakage occur.So in order to avoid the generation of the above situation, draws high pressure from side and integrally plug
Formula end bushing lifting seat also increases the exhausted of coil device body and inner wall of oil tank so not only there are sufficient installation space
Edge distance, strengthens safety precautions.
The above is only the preferred embodiment of the utility model, it is noted that for the ordinary skill of technical field
For personnel, without departing from the principle of this utility model, several improvement can also be made, wound is not being paid in these improvement
The scope of protection of the utility model is also should be regarded as under the premise of the property made labour.
