Description
Technical field:
The utility model relates to transformer equipment fields, and in particular to a kind of removable cooling device of transformer.
Background technique:
Its iron loss, copper loss and added losses are all transformed into heat when transformer station high-voltage side bus, make the part temperatures liter such as iron core, winding
It is high.The radiation processes of oil-immersed transformer are: the heat inside iron core, winding first being passed to its surface by heat transfer, is then passed
To oil, then by the free convection of oil to heat is constantly taken to the inner wall of fuel tank, radiator oil pipe, then by heat transfer hot
Amount passes to the outer surface of fuel tank, radiator oil pipe, is distributed heat in the air of surrounding by radiation and convection current again later.And
The radiation processes of forced oil-circulation transformer are then: will be sent into the oil duct in iron core or between winding on oil with oil-immersed pump, make it
In heat directly taken away by the cold oil with certain flow rate, and the hot oil on transformer upper layer is extracted out with oil-immersed pump, through cooler
It is re-fed into oil tank of transformer bottom after cooling, transformer oil is forced to carry out oily circulating cooling.
Traditional transformer cooling device is fixed in transformer case, since transformer is located outside work mostly
Make, and stream time is long, so transformer cooling device easily breaks down.Maintenance personal is in maintenance cooling device
When, it needs to open transformer case, due to being charged when transformer work, so staff's risk in maintenance is very high, it must
Transformer is powered off when wanting, it is made to stop working, this results in very big loss.Therefore, a kind of transformer move it is cold
But device urgently occurs.

Device repairs the removable cooling device of replacement to cooling device in the case where not powering off.
The following technical solution is employed for technical problem to be solved in the utility model to realize: a kind of transformer it is removable
Dynamic cooling device, including guide rail, the guide rail are fixedly connected with transformer base, block and have the cunning of air cooled box in the guide rail
Wheel, the air cooled box are cuboid metal box, and uncovered above the air cooled box, the air cooled box side is equipped with pull ring, the wind
Fan is fixedly connected in ice chest, the electric wire of the fan is connect with inside transformer power supply, the air cooled box and guide rail
In transformer case, the side of the transformer case is set there are two dodge gate, outside the dodge gate upper end and transformer
Shell articulated connection, the dodge gate lower end are fixedly connected with one end of connection sheet, and width and the height of the air cooled box are respectively less than
The width and height of dodge gate.
Preferably, the transformer case is equipped with air hole.
Preferably, the connection sheet is the articulated connection of two panels sheet metal, and the other end of the connection sheet is provided with elongate holes
Slot is fixedly connected with half-round metal item, the half-round metal radius on transformer case corresponding with the connection sheet
Less than the length of strip hole slot, strip hole slot just engages with half-round metal item, can thus lock for dodge gate.
Preferably, the length of the electric wire is 300cm, and reserved sufficiently long wire length facilitates air cooled box to pull out transformation
Device shell.
Preferably, the air cooled box is equipped with the switch of fan, the fan and switch and transformer close to dodge gate side
Internal power supply is connected in series, convenient when pulling out air cooled box, closes fan power supply.
Preferably, the iron core two sides inside transformer case corresponding to the dodge gate are respectively provided with air cooled box and guide rail,
It is more preferable to the heat dissipation effect of transformer to ensure, and when one of air cooled box failure, another remains to work normally.
Working principle of the utility model is:
In normal work, the air cooled box on transformer core both sides is iron core blowing by fan to the cooling device of transformer
To achieve the purpose that cool down to transformer.When cooling device breaks down, dodge gate is opened, the pull ring of air cooled box is held,
Air cooled box will skid off transformer case along guide rail, and maintenance personal can repair cooling device.It is finished in maintenance
When, the pulley of air cooled box is fastened on guide rail, Air cooler is pushed into transformer case along guide rail, closes dodge gate, it will even
Contact pin is buckled on transformer case, is lockked with lock.
The beneficial effects of the utility model are:
The utility model structure is simple, convenient and practical, by installation slide rail and opens up dodge gate, solves in cooling
It when plant failure, needs to open transformer case, the problem of causing safety hazard and power failure to delay work maintenance personal is easy, cold
But when device breaks down, air cooled box is pulled out by dodge gate, is not needed to dismantle transformer case again, be ensure that maintenance personal's
The normal operation of safety and transformer.Dodge gate is equipped with connection sheet, can lock for dodge gate, improve the antitheft of transformer
Property.
