All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, in the prior art, the detection of the reactors is generally the individual detection of the reactors, and the configuration difference between the reactors is not considered, which may cause uneven heating between the reactors to damage equipment.
For the convenience of understanding the present embodiment, a configuration detecting device of a reactor disclosed in the present embodiment will be described in detail first.
In an implementation manner, an embodiment of the present invention provides an emergency traction device, which is applied to a vehicle, and referring to a schematic structural diagram of an emergency traction device shown in fig. 1, the emergency traction device includes a variable frequency power supply 10, a phase shift module 20, an acquisition module 30, and an industrial control module 40, which are connected in sequence.
The variable frequency power supply is used for outputting a first voltage and transmitting the first voltage to the phase shifting module.
The phase shifting module is used for receiving the first voltage and carrying out phase change processing on the first voltage to obtain a second voltage; the phase-shifting module is also connected with the reactor, and the second voltage is the power supply voltage of the reactor; and the output voltage and the output current of the phase-shifting module are the voltage and the current of the reactor. The output voltage and current of the phase-shifting module are both regarded as the voltage and current of the reactor to be tested.
The acquisition module is used for acquiring the voltage and the current of the reactor output by the phase-shifting module and transmitting the acquired voltage and the current of the reactor to the industrial control module.
The industrial control module is used for receiving the voltage and the current of the reactor, and calculating the impedance and the power factor of the reactor according to the received voltage and the current of the reactor so as to complete the configuration detection of the reactor.
The configuration detection device of the reactor provided by the embodiment of the invention comprises a variable frequency power supply, a phase-shifting module, an acquisition module and an industrial control module which are sequentially connected, outputting a first voltage through a variable frequency power supply, transmitting the first voltage to a phase-shifting module, receiving the first voltage by the phase-shifting module, the phase shift module is also connected with the reactor, the second voltage is the power supply voltage of the reactor, the output voltage and the output current of the phase-shifting module are the voltage and the current of the reactor, the acquisition module acquires the voltage and the current of the reactor output by the phase-shifting module and transmits the acquired voltage and the acquired current of the reactor to the industrial control module, therefore, the industrial control module receives the voltage and the current of the reactor, and calculates the impedance and the power factor of the reactor according to the received voltage and the current of the reactor so as to complete the configuration detection of the reactor. The invention relates to a device for detecting a reactor, which is characterized in that the existing detection of the reactor is generally the detection of an individual reactor, even if the detection of the individual reactor is not problematic, the problem of unbalanced reactance and the like can exist in the configuration among the reactors, for example, the unbalanced reactance exists among three phases of a three-phase reactor, the uneven heating among the three phases of the reactor can be caused, and equipment is damaged.
Referring to a schematic structural diagram of another reactor configuration detection device shown in fig. 2, on the basis of fig. 1, a filter circuit 301, a three-phase collector 302, a temperature sensor 303, a voltage converter 50, a protection switch 60, and a current converter 70 are also illustrated.
The phase shifting module comprises a series capacitor bank, and phase change processing is carried out on the first voltage by adjusting the capacitance value in the series capacitor bank; or the phase shifting module comprises a parallel capacitor bank, and the phase change processing is carried out on the first voltage by adjusting the capacitance value in the parallel capacitor bank.
The phase shift module is one of the core innovation points of the embodiment of the invention, and is used for analyzing the consistency of a plurality of reactors by changing the phase shift phase; this represents a wider adaptability to catch defects, because: the three-phase consistency characteristics or matching degree of reactors with different insulation structures and winding relative relations caused by manufacturing are difficult to comprehensively reflect under a single frequency or phase condition, and the phase of a three-phase test signal is changed, so that whether the matching difference between the three-phase reactors is consistent in the whole test signal phase change range or not is analyzed. Practical test experience shows that when the frequency and the phase of a test signal are changed, the current of the three-phase reactor does not always show a 120-degree relative relationship, and therefore some hidden matching hidden dangers can be found. When the circuit actually runs, under the influence of an overvoltage signal, a lightning impulse signal or other surge signals of the operation switch, a certain phase in the three-phase reactor can bear a voltage or a current value exceeding rated parameters, so that the reactor is damaged.
The industrial control module is further connected with the variable frequency power supply, and the industrial control module is used for receiving power supply configuration information input by a user and adjusting the amplitude, the frequency and the phase angle of the variable frequency power supply based on the power supply configuration information.
The acquisition module comprises a filter circuit and a three-phase collector which are sequentially connected, and the three-phase collector is used for acquiring the voltage and the current of the reactor acquired by the phase-shifting module; the filter circuit is used for filtering clutter from the voltage and the current before collection, and the filter circuit can be an LC filter circuit or an RC filter circuit.
The device also comprises a voltage converter arranged between the phase-shifting module and the acquisition module and a current converter connected with the voltage converter, wherein the voltage converter is used for converting the working voltage obtained by the phase-shifting module into a voltage matched with the working voltage of the acquisition module, and the current converter is used for converting the current of the reactor output by the phase-shifting module into a voltage so as to provide the voltage for the acquisition module.
The device also comprises a protection switch connected with the phase-shifting module, and the protection switch is used for disconnecting the line when the temperature of the line where the phase-shifting module is located exceeds a preset threshold value.
The acquisition module also comprises a temperature sensor, and the temperature sensor is used for detecting the temperature of the reactor; the acquisition module is also used for conveying the detected temperature of the reactor to the industrial control module. The variable frequency power supply comprises a three-phase variable frequency power supply.
Specifically, the current converter is arranged in a load loop at the output end of the phase-shifting module, and the phase-shifting module is connected with the tested reactor in series, so that the output current passing through the phase-shifting module is the current of the reactor, the voltage at the output end of the phase-shifting module is connected with the tested reactor through a switch, namely the protection switch, and the voltage at the output end of the phase-shifting module is equal to the voltage at the tested reactor under the condition of neglecting the voltage drop of the switch. The variable frequency power supply can provide a power supply for the reactor, the voltage of the variable frequency power supply can be 1V-400V alternating current voltage, the frequency range is 0.1Hz-4000Hz, the waveform is square wave or sine wave, and the power is 1-1.5 kW.
The phase-shifting module can be a series capacitor bank, a parallel capacitor bank or an RC parallel branch circuit realized in a manual or numerical control mode, and the capacitance value and the resistance value in the phase-shifting module can be adjusted in the manual or numerical control mode.
In one embodiment, the phase shift module can satisfy the phase shift function of 0-degree resistance value, that is, in a manual or numerical control mode, there is a control working point, which satisfies the condition that the series resistance value of the phase shift module is zero and the parallel resistance value is approximately open circuit. In this state, the phase-shifting module and the reactor do not generate any reactive circuit interaction. The acquisition module is a signal conditioning circuit with filtering and noise isolation functions and a voltage gain adjustment function and an analog-to-digital converter with a sampling rate of 12-16 bits, and at least 6 channels are formed. The industrial control module comprises a microprocessor chip for controlling the variable frequency power supply and the acquisition module.
The following is a specific example illustrating the case of the configuration detection of the reactor:
example 1:
variable frequency power supply is three-phase variable frequency power supply, and the reactor is three-phase reactor, and a schematic diagram of three-phase reactor section is shown in fig. 3, and the three-phase reactor is star type connection structure, and three-phase variable frequency power supply frequency is 60Hz, and voltage is 10V, and the module work of shifting the phase is at the 0 phase state of establishing ties the short circuit, and the three-phase parameter of test is:
TABLE 1 Power factor and impedance of three-phase reactors
Categories A B C Mean value of
Power factor 0.05 0.04 0.03 0.04
Impedance (L) 34.0 31 34.6 33.2
According to table 1, it can be seen that the B-phase power factor is not significantly abnormal, but the impedance value is greatly different.
Example 2:
the method is the same as the embodiment 1, except that a three-phase reactor is connected with a three-phase capacitor in parallel, the three-phase reactor and the three-phase capacitor generate reactive current interaction under the action of a three-phase variable frequency source, and the test values are as follows:
TABLE 2 Power factor and impedance of three-phase reactor shunt three-phase capacitor
Categories A B C Mean value of
Power factor 0.07 0.09 0.07 0.94
Impedance (L) 34.0 33.3 34.3 33.2
Under the action of the reactive capacitor, reverse current generated inside the three-phase reactor interacts with the capacitor, so that internal temperature rise is increased, and impedance and power factor are obviously changed under the coordination action of the capacitor.
As shown in phase B, the power factor is the highest, theoretically, the higher the air-core reactor is, the better the air-core reactor is, but through impedance comparison, the impedance value of the loop is lower, the decrease of the reactance value is not enough to compensate for the increase of direct-current resistance caused by temperature rise, and therefore the condition that the three-phase reactor winding is disconnected and short-circuited can be preliminarily analyzed. According to this situation, the relevant worker can take an operation of replacing the reactor.
Example 3:
the same as in examples 1 and 2 are not repeated, and example 3 is different in that: and additionally observing the vibration signal and the temperature of the three-phase reactor, inputting the signals into the acquisition module through the vibration test sensor and the temperature test sensor which are temporarily installed in the air reactor, and then calculating and displaying through the industrial control module. Under the condition, the configuration of the three-phase collector is 12 channels, wherein 6 channels are used for collecting three-phase voltage waveforms and three-phase current waveforms so as to calculate impedance, power factor and the like, and the other 6 channels are respectively used for collecting three-phase temperature and vibration signals.
And (3) setting the temperature acquisition as the numerical value of the end connection point of the three-phase reactor, and testing the acoustic sensor with a vibration signal of 10-20 kHz.
TABLE 3 vibration values and temperatures of three-phase reactors
Categories A B C Mean value of
Vibration (dB) 59 61 54 58
Temperature (degree) 55 55 55 55
The vibration hazard warning value is set to 65dB, the temperature is set to 58 ℃, and all the values in the table 3 are in the qualified range.
Of course, in order to perform the detection of the ultrasonic range, the acoustic sensor may be replaced by an ultrasonic sensor, and the description thereof is omitted.
It should be noted that, the methods based on the three-phase architecture proposed in embodiments 1 to 3 are not only used for finding out a defective three-phase reactor, but also can improve the process of field three-phase configuration, including loosening of a connecting component, a matched load value, and the like, when a field test is performed, all adjacent accessories of the three-phase reactor will affect the matching degree of the three phases, and if the matching degree of the three phases is poor, even if the impedance value and the power factor are in a satisfactory range, an additional heating increment may be obtained from a certain phase due to three-phase imbalance in the later period, which may cause damage.
In addition, the three-phase variable frequency power supply has a variable frequency function, and in practical application, in order to prevent impact influence, whether the characteristics of the three-phase reactor under the action of high-frequency current are consistent or not can be evaluated, the detection frequency can be increased, and corresponding parameter changes can be observed. And the three-phase collector can realize full-waveform collection, so that the signals obtained under the detection condition of high-frequency current and/or high-frequency voltage can be subjected to frequency domain transformation, such as wavelet or FFT Fourier analysis and other spectrum analysis methods.
In summary, the configuration detection device for the reactor provided by the embodiment of the invention includes the variable frequency power supply, the phase shift module, the acquisition module and the industrial control module which are sequentially connected, and since the existing detection for the reactor is generally the detection for the individual reactor, even if the detection for the individual reactor is not problematic, the configuration between the reactors may have problems such as unbalanced reactance, for example, the unbalanced reactance between the three phases of the three-phase reactor may cause uneven heating between the three phases of the reactor and damage equipment.
