Description
Technical field
The present invention relates to a kind of power industry equipment transformator, more particularly to a kind of straight pipe type circulation cooling transformator.
Background technology
China is vast in territory, and power delivery networks gather, and is required to transformator in the end of network to carry out voltage turn
Change.Heat to be produced in the transformator course of work, the too high efficiency that can affect voltage conversion of temperature causes the increasing being lost,
So the design of transformator is all paid much attention to heat dispersion, existing transformator is typically all to adopt radiating tube, and radiating tube is upper and lower
Two ends upper and lower UNICOM respectively with oil tank of transformer inner space, constitutes closed circuit, and whole closed circuit is less than
The height of oil tank of transformer, the transformer oil density of different temperatures are different, and in whole closed circuit, the oil temperature of transformer oil is by upper
Successively lower downwards, that is, upper strata temperature is higher than lower floor's temperature, and existing transformer core winding and transformer oil box cover
Spacing is less, thus can still have part iron core winding to be immersed in the higher oil reservoir of temperature, affects radiating, affects work effect
Rate, these still await technology solution.
The content of the invention
In order to solve the above problems, the invention provides a kind of straight pipe type circulation cooling transformator.
The technical solution used in the present invention is：A kind of straight pipe type circulation cooling transformator, including oil tank of transformer, radiating tube

Rise, isolating membrane protuberance amplitude in upper strata is equipped with the bullet of its both sides of UNICOM more than lower floor's isolating membrane protuberance amplitude on two-layer isolating membrane
Power seal；Radiating tube is divided into ascending tube and down pipe, and oil tank of transformer upper space passes through ascending tube and lower groove inner space
UNICOM, ascending tube are straight tube, and by lower groove sidewall in groove, in-position higher than lower groove depth 1/2nd becomes ascending tube
Depressor fuel tank lower space is entered in groove by lower trench bottom by down pipe and Xia Cao inner spaces UNICOM, down pipe, down pipe
It is higher than at least one centimetre of lower trench bottom into the port in groove.
Further, be provided with iron core and winding in the oil tank of transformer, iron core and winding be located at fuel tank height three/
In less than two spaces.
Further, the resilient seal mouth is externally provided with hoop.
Further, the hoop is elastic force ring.
Further, the ascending tube be five with, be connected to horizontal up house steward, up house steward is in charge of by up
Lower groove is connected to, up quantity of being in charge of is less than ascending tube quantity.
Further, the down pipe be ten with, be connected to horizontal descending house steward, descending house steward is in charge of by descending
Lower groove is connected to, up quantity of being in charge of is less than five.
The present invention participates in radiating circulation using conservator, can thus effectively improve the height of whole closed circuit, make
Transformer core winding top has the higher bigger space for taking transformer oil in, and in whole closed circuit, temperature is higher
Transformer oil laminar flow upwards all the time, and transformer core winding is all the time in the lower space of transformator oil reservoir, also
It is to be in the relatively low oil reservoir of oil temperature all the time, can thus makes iron core winding sufficiently lower the temperature, be operated in a lower temperature
In degree environment, improve work efficiency, and the present invention have that the middle part for being provided with two-layer periphery airtight connection swells upwards every
From film, transformer oil is sealed off, deformable surplus is big, reduce transformer oil and expand with heat and contract with cold the pressure change for causing, in pressure
When power is too high, transformer oil overcomes the resistance of lower floor's isolating membrane resilient seal mouth to enter the intermembranous space of two-layer isolation, two-layer isolation
The transformer oil in intermembranous space by upper strata isolating membrane not with air contact, can not only reuse but also can play seal every
From effect, when two-layer isolates intermembranous space is full of transformer oil hypertonia, transformer oil overcomes upper strata isolating membrane elastic force
The resistance of seal enters upper strata and isolates the intermembranous space with upper lid, and in this course, transformer oil is only to a direction stream
It is dynamic, countercurrently functional reliability will not be further increased with the fluid of air contact.
