Abstract
The utility model discloses a temperature control system for an oil immersed type transformer, which comprises a sensor (1) for measuring temperature of an oil top layer of the transformer, a controller (2) which is connected with an output end of the sensor (1), and a cooling fan (3) which is connected with an output end of the controller (2), wherein the output end of the controller (2) is further connected with the transformer (4); and the cooling fan (3) is arranged on the transformer (4). The temperature control system for the oil immersed type transformer disclosed by the utility model is reasonable in structure, steady in performance, strong in practicality, and capable of prolonging the service life of the transformer and reducing power failure, thereby increasing power supply reliability.
Description
Technical field
The utility model relates to a kind of temperature control system, is specifically related to a kind of oil-filled transformer and uses temperature control system.
Background technology
Along with the development of country, the resident living level improves constantly, and household electrical appliance are more and more; Power load is in rapid increase; Particularly in the peak of power consumption period, the frequent running overload of transformer, it is overheated that transformer occurs; The lighter has shortened the serviceable life of transformer, and weight person burns transformer and causes heavy losses.
The utility model content
To the deficiency that prior art exists, the oil-filled transformer that the utility model purpose provided and a kind ofly protect transformer, prolonged transformer serviceable life is used temperature control system.
To achieve these goals, the utility model is to realize through following technical scheme:
The utility model comprises sensor, controller that is connected with the sensor output terminal and the cooling blower that is connected with controller output end that is used for measuring transformer oil top layer temperature; Controller output end also is connected with transformer, and cooling blower is installed on the transformer.
Above-mentioned controller comprises casing, is arranged on the circuit board in the casing and is installed in the display screen that is used to show the transformer temperature on the casing.
What the sensor adopted is platinum resistance temperature sensor.
The utility model is rational in infrastructure, stable performance, practical, can prolong transformer serviceable life, reduces power outage, improves the reliability of power supply.
Description of drawings
Fig. 1 is the electrical equipment catenation principle figure of the utility model;
Fig. 2 is the structural representation (transformer 4 does not draw among the figure) of the utility model.
Each label among the figure: sensor 1, controller 2, casing 21, display screen 22, cooling blower 3, transformer 4.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with embodiment, further set forth the utility model.
The utility model comprises and is installed in sensor 1, controller 2 that is connected with sensor 1 output terminal and the cooling blower 3 that is connected with controller 2 output terminals that is used for measuring transformer oil top layer temperature on the transformer 4; Controller 2 output terminals also are connected with transformer 4, and cooling blower 3 is installed on the transformer 4.
The principle of work of the utility model is following:
When sensor 1 detects transformer oil temperature T above the regulation mxm.; Controller 2 sends enabling signal to cooling blower 3; Make cooling blower 3 give transformer 4 heat radiations, prolonged the serviceable life of transformer 4, can guarantee that transformer 4 can normally move when peak of power consumption.
When sensor 1 detected transformer oil temperature T and is reduced to normal temperature range (prescribed minimum≤T≤regulation mxm.), cooling blower 3 was out of service.
When sensor 1 detected transformer oil temperature T above prescribed minimum, controller 2 sent trip signal to transformer 4, made transformer 4 tripping operations, with protection transformer 4.
In the present embodiment, what sensor 1 adopted is platinum resistance temperature sensor.
More than show and described ultimate principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the instructions that the utility model just is described; 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 variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
