Abstract
The utility model discloses a transformer cooling device. The device comprises a transformer cabinet and a radiating fan; the transformer cabinet is provided with an upper cabinet door, a lower cabinet door, a left cabinet door, a right cabinet door, a front cabinet door and a rear cabinet door; radiating windows are respectively arranged on the front and the rear cabinet doors; the radiating fan is mounted on the upper cabinet door; and a temperature control switch is mounted on a transformer and is connected with the radiating fan. The transformer cooling device can discharge heat generated during the operation process of the transformer, reduces tripping frequency and power loss and protects the power supply network; and meanwhile, the utility model has the advantages of no volume increment of the transformer, low manufacturing cost and use cost, and convenient maintenance.
Description
Technical field
The utility model relates to a kind of equipment heat sink, relates in particular to the heat sink of electric power transformer commonly used.
Background technology
Along with expanding economy, each corner in the electrified all spectra that almost runs through national economy, the application of power transformer more and more widely, the safe in utilization of power transformer also becomes more and more important simultaneously.Transformer can produce a large amount of heats when running, cause the temperature of transformer to raise and frequent tripping operation, as the long term high temperature operation, then easily causes insulation property to reduce, and the loss that increases electric power causes the transformer scaling loss when serious, jeopardizes supply network safety.
The radiating mode of common transformer (as SC9, SC10) is, in transformer cabinet bottom radiator fan is installed, heat radiation window heat radiation by the bottom, because the hot-air density that produces during operation is little, hot-air accumulates in transformer cabinet top in a large number and can't discharge, radiating effect not clearly, and this radiating mode a large amount of dust of accumulation etc. in the long-time running process because in the equipment, easily cause stopping up fan, directly cause heat abstractor to move.
Patent No. ZL 200420077879.1 discloses a kind of cooling system of power transformer, this system comprises: one or more distributor headers, one or more gatherer heads, also comprise many cooling water pipes between distributor header and gatherer head, also comprise the recirculated cooling water case that is arranged on many cooling water pipe outsides, the dielectrically insulating fluid in the cooling water pipe is cooled off; Wherein distributor header is communicated with the dielectrically insulating fluid of power transformer, the distribution of dielectrically insulating fluid in the power transformer is entered in the many cooling water pipes, the gatherer head also is communicated with the dielectrically insulating fluid of power transformer, will be collected by the dielectrically insulating fluid that flows out in the many cooling water pipes to enter in the power transformer.This patent team's transformer is fast cooled off, but volume Peng is big, production cost height, inconvenient maintenance.
The utility model content
The utility model can't in time be discharged because of producing a large amount of heats when running for solving transformer, cause the temperature of transformer to raise and frequent tripping operation, loss simultaneously increases electric power, cause the transformer scaling loss when serious, jeopardize supply network safety, all the other heat abstractor volumes are big, cost height, problem such as inconvenient maintenance and a kind of transformer heat sink is provided.
Address the above problem, the technical scheme that the utility model is taked is a kind of transformer heat sink, comprise transformer case, described transformer heat sink also is provided with radiator fan, transformer case is provided with Over-The-Counter door, lower cabinet door, left cabinet door, right cabinet door, front cabinet door and rear cabinet door, and front cabinet door and rear cabinet door are provided with the heat radiation window, on the Over-The-Counter door radiator fan are installed, temperature detect switch (TDS) is installed on the transformer, and temperature detect switch (TDS) connects radiator fan.When the temperature of transformer is raised to certain numerical value, temperature detect switch (TDS) on the transformer is opened, the terminal radiator fan that connects of temperature detect switch (TDS), and heat radiation window and the radiator fan that is installed on the Over-The-Counter door form a plurality of heat dissipation wind channels, the hot-air that transformer produces is discharged in radiator fan work.
As preferably, 1～5 radiator fan is installed on the Over-The-Counter door on the transformer case.In time the hot-air that transformer is produced is discharged.
As preferably, heat radiation window, radiator fan and transformer bay form cavity, and form heat dissipation wind channel between transformer cabinet inside and radiator fan.Make air and extraneous air formation convection current in the transformer, when the hot-air that transformer produces is discharged cool exterior air is sucked, in time transformer is cooled off.
As preferably, temperature detect switch (TDS) is opened temperature and is arranged on 30 ℃～100 ℃.
The beneficial effects of the utility model are: in time discharge the heat that transformer produces when running, reduce tripping frequency, reduce power consumption, and protection supply network safety, the while does not increase the volume of transformer, and production cost and use cost are low, and be easy to maintenance.
