Abstract
The utility model discloses an energy-saving oil immersed transformer, which comprises a bracket (1), a transformer body, a cooling fan (3) and a temperature controller, wherein the transformer body comprises an oil tank (21) which is arranged on the bracket (1) and a transformer body (22) and transformer oil (23) which are arranged in the oil tank (21); the cooling fan (3) is arranged on the bracket (1); the temperature controller is arranged on the oil tank (21) and comprises a control module (41) and a probe (42) which is in contact with the top layer transformer oil (23); the probe (42) is connected with an input end of the control module (41); and the cooling fan (3) is connected with an output end of the control module (41). The oil immersed transformer is particularly suitable for occasions of large load during short-term power utilization and small load during power utilization in most of time; the power utilization quality can be guaranteed, the equipment breakdown can be reduced, and the service life of the transformer can be prolonged; and the transformer has the advantages of rational structure, stable performance and the like.
Description
Technical field
The utility model relates to a kind of oil-filled transformer, what be specifically related to is a kind of energy-saving oil immersion formula transformer.
Background technology
Along with the development of country, resident living improves constantly, and household electrical appliance are more and more, and power load is in rapid increase, and particularly in the peak of power consumption period, the frequent running overload of transformer has shortened useful life of transformer.And by increasing the capacity of transformer, the corresponding increase of transformer noload losses has not only increased the initial stage input cost, and has increased electric cost when low power consumption, the waste resource.
The utility model content
At the deficiency that exists on the prior art, the utility model purpose is to be to provide a kind of increase capacity that need not just can guarantee to reduce cost the energy-saving oil immersion formula transformer that can normally move, to economize on resources when peak of power consumption.
To achieve these goals, the utility model is to realize by the following technical solutions:
The utility model comprises support and transformer body, and the transformer body comprises rack-mount fuel tank and is arranged on fuel tank interior transformer body and transformer oil, also comprises cooling blower that is arranged on the support and the temperature controller that is installed on the fuel tank; Temperature controller comprise control module and with the contacted probe of top layer transformer oil, the probe be connected with the input of control module, cooling blower is connected with the output of control module.Probe is used for detecting the temperature of top layer transformer oil, and control module is controlled the startup of cooling blower and stopped.
Above-mentioned transformer body comprises iron core and is arranged on the outer winding of iron core that winding comprises low-voltage coil and is arranged on the outer high-tension coil of low-voltage coil.
Above-mentioned iron core is formed by stacking by grain-oriented cold-reduced silicon sheet.
Above-mentioned cooling blower is outdoor bottom blowing formula blower fan.
Above-mentioned probe is the platinum resistance probe.
It is big that the utility model is particularly suitable for the electricity consumption short-term load (duty), and the little place of most of the time power load can guarantee with electricity quality, reduces equipment breakdown, prolong the useful life of transformer, and have rational in infrastructure and steady performance.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is a structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
The utility model comprises support 1 and transformer body, the transformer body comprises the fuel tank 21 that is installed on the support 1 and the transformer body 22 and the transformer oil 23 that are arranged in the fuel tank 21, also comprises cooling blower 3 that is arranged on the support 1 and the temperature controller that is installed on fuel tank 21 walls; Temperature controller comprise control module 41 and with top layer transformer oil 23 contacted probes 42, probe 42 is connected with the input of control module 41, be used for detecting the temperature of top layer transformer oil 23, cooling blower 3 is connected by the output of lead with control module 41, and control module 41 is controlled the startup of cooling blowers 3 and stopped.
The control module 41 and the control method thereof of the utility model temperature controller are prior art, do not repeat them here.
The utility model operation principle is as follows:
Utilize probe 42 to detect the temperature of top layer transformer oil 23, when the transformer running overload, top layer transformer oil 23 temperature raise, when temperature surpasses setting, control module 41 sends to cooling blower 3 and opens the signal of telecommunication, and cooling blower 3 is activated, thereby gives the transformer radiating and cooling; When top layer transformer oil 23 temperature were reduced to set point, control module 41 sent to cooling blower 3 and closes the signal of telecommunication, and cooling blower 3 is out of service.
The cooling blower 3 of present embodiment is outdoor bottom blowing formula blower fan.
The probe 42 of present embodiment is the platinum resistance probe.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
