It should be noted that due to generally using voltage method in existing air reactor insulation failure detection method, if
Insulation failure detection is carried out to air reactor using current method, then needs to input high current in air reactor, is easy
Now burn the core of air reactor.
Therefore, using by the method for high-frequency current input air reactor in the present invention, high-frequency current can pass through frequency conversion
Power supply realizes accurate current control, and high-frequency signal is mainly propagated along the surface of insulating layer of air reactor, so that insulating layer
The characteristics of surface heat, and then can more safely and accurately air reactor insulation fault be detected.
In addition, it should also be noted that, the frequency range of above-mentioned high-frequency current signal is 1kHz-100kHz；Above-mentioned
First predetermined period can be not specifically limited in embodiments of the present invention by testing staff's sets itself according to the actual situation.
In embodiments of the present invention, as shown in Fig. 2, step S108 further includes following steps:
Step S1081 is based on the target information, and whether determine the air reactor insulation fault occurs；

In embodiments of the present invention, it can determine whether air reactor goes out by target information and target component respectively
Existing insulation fault, has certain physical significance due to target component, determines air reactor by target component
Whether insulation fault is occurred, and accuracy is higher, also has higher practical value.
In embodiments of the present invention, as shown in figure 3, step S1081 the following steps are included:
Step S11, the conductivity information of line footpath temperature information and the air reactor based on the air reactor,
When the line footpath temperature for calculating the air reactor is target temperature, target temperature conductance corresponding with the target temperature

In embodiments of the present invention, conductivity is the parameter directly related with metal material, can be recognized in pure metal material
It is the inverse of resistivity for conductivity.But in practical application, conductivity is amount very relevant to temperature, the temperature of metal material
Higher, the conductivity of metal material is lower.And with the difference of metal material doping material, the numerical value of conductivity and the pass of temperature
It is that irregular nonlinear characteristic can be presented in characteristic.
Therefore, when turn-to-turn short circuit occurs for air reactor, SI semi-insulation material changes, and causes in higher temperature ring
When border, there is biggish difference in the change trend and normal value of conductivity, therefore, when the line footpath temperature of air reactor is target
It, can if the ratio of target temperature conductivity corresponding with target temperature is more than or less than the second preset range when temperature
To judge that insulation fault occurs in air reactor.
It should be noted that since corresponding first preset range of different types of air reactor is also different, because
This, is not specifically limited the first above-mentioned preset range specific value, above-mentioned target temperature can by testing staff according to
Actual conditions sets itself, is not specifically limited in embodiments of the present invention.
In embodiments of the present invention, as shown in figure 3, step S1081 further includes step:
Step S21, calculate at the time of the air reactor inputs the high-frequency current of the predeterminated frequency with the line footpath

In embodiments of the present invention, it calculates at the time of air reactor inputs the high-frequency current of the predeterminated frequency and line footpath
Period between at the time of temperature is target temperature.
If the above-mentioned period is more than or less than second preset range, it is determined that go out air reactor and insulation event occur
Barrier.
When the period being greater than the second preset range, the usual heating-up time is longer to reach heating target temperature, or heating is non-
Linear region is too long, that is, consumes a longer time in inflection point transitional region, and it is stranded to be considered air reactor turn-to-turn insulation.
For example, the above-mentioned period is 6 minutes, when the second preset range is 4-5 minutes, the period is greater than preset range, then
It is considered that there is the stranded failure of turn-to-turn insulation in air reactor.
When the period is less than the second preset range, there is the failure of turn-to-turn short circuit in air reactor under normal conditions.
For example, the above-mentioned period is 3 minutes, when the second preset range is 4-5 minutes, the period is greater than preset range, then
It is considered that the failure of hollow reactor interturn short circuit.
In addition, it should also be noted that, since corresponding second preset range of different types of air reactor is also not
With, therefore, the second above-mentioned preset range specific value is not specifically limited.

In addition, it should also be noted that, since the corresponding third preset range of different types of air reactor is also not
With, therefore, above-mentioned third preset range specific value is not specifically limited.
The vibration energy signal of air reactor is another the important finger for reacting the turn-to-turn insulation failure of air reactor
Mark.But after common turn-to-turn insulation breakdown, vibration signal is not easy directly to measure, and reason is: (a) air reactor point multilayer knot
The position of structure, turn-to-turn insulation breakdown is more in outer layer, is more easily detected, conversely, being more in internal layer, then is more difficult to identify.(b)
The vibration signal that turn-to-turn insulation breakdown generates is inherently very faint, if tested using traditional power frequency component, needs non-
Often huge power current device could obtain corresponding vibration energy signal.
Due to using high-frequency current signal in the embodiment of the present invention, the energy of vibration signal is exacerbated, to reduce spy
The technical difficulty of identification is surveyed, meanwhile, rule of thumb, in order to enhance the accuracy of the vibrational energy information number got, therefore need
To believe the vibrational energy of acquisition air reactor within the 5-15 minute after the line footpath temperature of air reactor reaches target temperature
Number.
In embodiments of the present invention, as shown in figure 4, the method also includes following steps:
Step S202 increases default according to the frequency that the second predetermined period will input the high-frequency current of the air reactor
Value, obtains frequency data group A=(A1, A2...An), wherein AiTo input the air reactor in i-th of predetermined period
The frequency of high-frequency current, n are the quantity of the predetermined period；
Step S204 obtains the line footpath temperature of the air reactor in each predetermined period, obtains temperature information group B=
(B1, B2...Bn), wherein BiThe line footpath temperature of the air reactor at the end of for i-th of second predetermined periods；
Step S206 is based on the frequency data group and the temperature information group, target signature curve is constructed, if the mesh
Marking indicatrix is nonlinear characteristic curve, it is determined that goes out the air reactor and breaks down.
In embodiments of the present invention, firstly, according to the second predetermined period, the frequency of the high-frequency current of air reactor will be inputted
Rate increases preset value, obtains frequency data group.
It should be noted that the second above-mentioned predetermined period can by staff's sets itself according to the actual situation,
It is not specifically limited in the embodiment of the present invention, the second predetermined period is 1 minute under normal circumstances.
Then, the line footpath temperature for obtaining air reactor when each second predetermined period beam, obtains temperature information group.
Finally, target signature curve is constructed according to frequency information group and temperature information group, if target signature curve is non-
Linearity curve, then there is insulation fault in the air reactor.
