In order to avoid the problem of failure of the power electronic device due to a harsh environment or reduction of the service life of the power electronic device caused thereby, as shown in fig. 1, an embodiment of the present invention provides an isolation device for a power electronic device, including:
an isolation box body 01 sleeved outside the isolation object; an insulation fixing device 11 for fixing an isolation object 02 is arranged in the isolation box body 01; the isolation box 01 is filled with insulating oil; the isolation box body 01 is made of metal; the isolated object 02 includes a power electronic power device and a control drive unit;
the isolation box body 01 is provided with an external connection through hole 12 capable of being sealed in an insulating mode, and an external connection wire 13 of the isolation object 02 is connected with one of a power supply, a load and a superior controller or any combination of the power supply, the load and the superior controller through the external connection through hole 12.
In the present invention, the object of use of the isolation device (i.e., the isolation object) may be a power electronic device that includes devices such as a frequency converter, SVG, UPFC, a rectifier, a direct-current power supply, and is used in a severe environment such as high temperature, low temperature, humidity, dust, or air pollution; specifically, the isolation object 02 may include a power electronic power device, a control drive unit, and the like; in practical application, the power electronic power device and the control driving unit can adopt an IGBT complete set of modules, so that the power electronic power device and the control driving unit are suitable for working after being soaked in insulating oil for a long time.
The insulating oil filled in the isolation box body 01 can effectively isolate the isolation object 02 from the external environment, so that the influence of severe environment on the power electronic device is avoided.
Next, in the present invention, the isolation box 01 is further provided with an external connection through hole 12 that can be sealed in an insulating manner, so that the external connection line 13 of the isolation object 02 can be connected to external devices such as an external power supply, a load, and a higher-level controller through the external connection through hole 12 by a sealing member such as an insulating bushing.
Preferably, as shown in fig. 2, the outer wall of the isolation box 01 of the present invention may further include heat dissipation fins 14; thus, the problem of temperature rise caused to the isolated object due to isolation can be further reduced; furthermore, a convex part 15 can be arranged on the inner wall of the isolation box body 01, so that the contact area of the insulating oil and the isolation box body 01 is increased to improve the heat conduction efficiency;
in a high-temperature severe environment or under the condition that the heat generated by the isolation object is too large, in order to maintain the normal working condition of the isolation object, as shown in fig. 3, the isolation device of the present invention may further include an insulating oil displacement mechanism (not shown in the figure); the insulating oil displacement mechanism realizes displacement of the insulating oil inside and outside the isolation box body 01 through an oil inlet 17 and an oil outlet 16 which are arranged on the isolation box body 01. Thus, by replacing the insulating oil in the isolation tank 01, the ambient temperature of the isolation object 02 can be rapidly reduced, and the temperature of the isolation object 02 can be prevented from being too high.
Preferably, the insulating oil displacement mechanism in the present invention may further include a temperature acquisition unit (not shown in the figure) and a control unit (not shown in the figure); the temperature acquisition unit is used for acquiring temperature data of the insulating oil; the control unit controls the opening and closing of the insulating oil displacement mechanism according to a control instruction generated by the temperature data. Specifically, the control unit may include an instruction generating module with a preset rule, so as to generate a corresponding control instruction according to the data acquired by the temperature acquiring unit, so as to start or close the insulating oil displacement mechanism, for example, it may be set that when the temperature of the insulating oil exceeds a preset upper limit value, the control unit may generate a control instruction for starting the insulating oil displacement mechanism to cool the isolation object 02, so that the isolation object 02 may be automatically and effectively temperature-protected, so as to reduce the influence of high temperature on the device.
Preferably, as shown in fig. 4, in the present invention, a draft tube may be further disposed in the isolation box 01; the guide pipe comprises a conveying part 18 and a drainage part 19; wherein, one end of the conveying part 18 is communicated with the oil outlet 16, and the drainage part 19 is arranged at the position close to the isolation object 02; different locations of the drain 19 include a plurality of drainage holes. When the temperature of the isolation object 02 is too high, the temperature of the insulating oil closest to the isolation object 02 is the highest, and the replacement of the high-temperature insulating oil can be accelerated through the flow guide pipe, so that the speed and the efficiency of the temperature control of the isolation object 02 are accelerated.
In order to make the replacement speed of the insulating oil in the vicinity of each position of the isolation object 02 uniform, in practical application, the distribution mode of the plurality of drainage holes may be further set as follows: the drainage holes in the drainage portion 19 near one end of the delivery portion 18 are less densely distributed than at the other end. Specifically, if the densities of the plurality of drainage holes are the same, when the insulating oil is pumped out through the conveying part 18, the negative pressure of the drainage holes close to the conveying part 18 is large, and further, the flow rate is high, and the flow rate of the drainage holes far away from the conveying part 18 is low, so that the positions of the isolation object 02 cannot be synchronously cooled. The distribution density of the drainage holes close to one end of the conveying part 18 can be set to be smaller than that of the drainage holes at the other end, so that the replacement speed of the insulating oil near each position of the isolation object 02 can be consistent, and the cooling effect on the isolation object 02 is improved.
Furthermore, when the volume of the isolation object is larger, the drainage part can be designed to comprise a plurality of branches, so that the temperature of the isolation object can be controlled more uniformly and efficiently.
The application environment of the invention is severe, for example, in a humid environment, after moisture enters the isolation box body, the electric fields of unstable high-frequency pulse and the like can cause the insulating oil to generate impurities in the isolation box body due to electric power decomposition, thereby causing the reduction of the insulating resistance and the reduction of the insulating strength, further reducing the breakdown voltage of the insulating oil, and further leading the working performance of an isolation object to be reduced; for this reason, in the present invention, an oil filter may be further provided to filter the exchanged insulating oil; specifically, the oil filter is communicated with the insulating oil displacement mechanism, so that the insulating oil displaced by the isolation box body can be effectively filtered.
In summary, in the present invention, in order to reduce the failure rate of the power electronic devices in severe environments such as high and low temperatures, humidity, air pollution, and the like, and to prolong the service life of the power electronic devices, the isolation device of the power electronic device is provided in the present invention, specifically, the isolation box is sleeved outside the power electronic device which needs to be isolated, so as to avoid the temperature rise after the power electronic device is isolated from affecting the normal operation of the power electronic device, in the present invention, not only the isolation box is made of metal, but also the insulation oil with excellent heat conductivity is provided in the isolation box, so that the temperature of the power electronic device caused by the isolation can be avoided from being too high.
According to the invention, the power electronic device can be effectively isolated from the external severe environment under the condition of avoiding overhigh temperature caused by the fact that the power electronic device is isolated, so that the problems of faults of the power electronic device caused by the severe environment and reduction of the service life of the power electronic device caused by the faults are avoided.

It is not intended to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching.
