Description
Technical field
The utility model relates to a kind of cooling system, and specifically a kind of reserved cooling system for transformer, belongs to transformer accessory equipment technical field.
Background technology
Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core.Major function has voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing etc., applies very extensive.
Transformer is after long-term use, and internal temperature is higher, tends to be provided with a cooling device at its outer surface.As shown in Figure 1, in the outside of transformer 3, a cooling fan of being controlled by electronically controlled motors 21 can be set, to the processing of lowering the temperature of its inside.But because the installation site of transformer is outdoor often, cooling fan 1 is easy to, because because extraneous factor causes some faults, reduce cooling-down effect, enters the normal use that affects transformer.
Summary of the invention
For the problems referred to above, the utility model provides a kind of reserved cooling system for transformer, guarantees cooling-down effect, guarantees the normal use of transformer.
For achieving the above object, a kind of reserved cooling system for transformer of the utility model, comprises transformer and cooling fan, and cooling fan is arranged on the centre position in transformer outside, and cooling fan one side is provided with electronically controlled motors.
On the basis of said structure, current sensor, mounting bracket, cooler and cooler control system have also been increased.The base top of transformer has groove, and the bottom enclosure place of transformer respective slot has a plurality of air admission holes.Cooler is arranged in the groove of opening on base top, and cooler air port is close in the bottom enclosure of transformer, and cooler control system is installed on cooler, and storage pellet is installed in cooler control system; The electronically controlled motors of cooling fan is connected with the cooler control system signal of telecommunication; Mounting bracket is spill, is arranged on the below in cooling fan outside; Current sensor is arranged on the inside upper surface of mounting bracket by securing member, current sensor is connected with the cooler control system signal of telecommunication.
Further, also comprise gas sensor, gas sensor is arranged on the inside upper surface of mounting bracket by securing member, is connected with the cooler control system signal of telecommunication.
Further, the front-back of mounting bracket is provided with rotatable plastic dam.
Further, in the circuit of current sensor and gas sensor, be provided with filter circuit.
Further, cooler is arranged on by support in the groove of opening on base top, in the space between support, is full of elastic layer, and elastic layer is rubber layer.
Operation principle: transformer is normally worked, cooling fan carries out cooling to its inside, and the electric current that current sensor detects is the cooler rated current that in cooler control system, storage module stores in advance.When cooling fan breaks down and causes the problems such as short circuit, the electric current that current sensor detects is converted into signal and is delivered to cooler control system, factor data is different from storage in advance, cooler control system is controlled the electronically controlled motors of cooling fan and is closed, and opens cooler simultaneously the inside of transformer is lowered the temperature.
Beneficial effect: the utility model, in the situation that cooling fan goes wrong, can be lowered the temperature to transformer inside by standby cooler, has guaranteed the effect of lowering the temperature, and has guaranteed the normal use of transformer.

Fig. 2 is operation principle block diagram of the present utility model.
In figure: 1, cooling fan, 2, electronically controlled motors, 3, transformer, 4, base, 5, current sensor, 6, gas sensor, 7, cooler control system, 8, cooler, 9, mounting bracket.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of reserved cooling system for transformer, comprises transformer 3 and cooling fan 1, and cooling fan 1 is arranged on the centre position in transformer 3 outsides, and cooling fan 1 one sides are provided with electronically controlled motors 2; It is characterized in that, also comprise current sensor 5, mounting bracket 9, cooler 8, cooler control system 7; Base 8 tops of transformer 3 have groove, and the bottom enclosure place of transformer 3 respective slot has a plurality of air admission holes; Cooler 8 is arranged in the groove of opening on base 8 tops, and cooler 8 air ports are close in the bottom enclosure of transformer 3, and cooler control system 7 is installed on cooler 8, and storage pellet is installed in cooler control system 7; The electronically controlled motors 2 of cooling fan 1 is connected with cooler control system 7 signals of telecommunication; Mounting bracket 9 is spill, is arranged on the below in cooling fan 1 outside; Current sensor 5 is arranged on the inside upper surface of mounting bracket 9 by securing member, current sensor 5 is connected with cooler control system 7 signals of telecommunication.
As the utility model, further improve, also comprise gas sensor 6, described gas sensor 6 is arranged on the inside upper surface of mounting bracket 9 by securing member, is connected with cooler control system 7 signals of telecommunication.Using current sensor 5, increasing gas sensor 6, the smell sending during to short circuit detects, thereby has further increased the processing speed of whole system, guarantees that cooling continuing carry out.
As the utility model, further improve, the front-back of mounting bracket 9 is provided with rotatable plastic dam, prevents that transducer is affected in bad weather.
As the utility model, further improve, in the circuit of current sensor 5 and gas sensor 6, be provided with filter circuit, guarantee the accurate of detection.
