[0025] Embodiment 1

[0026] According to an embodiment of the present invention, an embodiment of a method for detecting moisture in an on-pole switch is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here.

[0027] Figure 1 It is a flowchart of the method for detecting moisture in an on-pole switch according to an embodiment of the present invention. As Figure 1 shown, the method includes the following steps:

[0028] S102. Receive a moisture detection request, where the moisture detection request carries an on-pole switch identifier of a target;

[0029] In step S102 provided in the present application, a moisture detection request is received.

[0030] Among them, a moisture detection request is involved. The moisture detection request is a request for triggering the moisture detection process of the pole-mounted switch. The moisture detection request carries the target pole-mounted switch identifier, which is used to clarify the specific pole-mounted switch that needs to be subjected to moisture detection.

[0031] Among them, a target pole-mounted switch identifier is involved. The target pole-mounted switch identifier is an identifier used to uniquely identify a specific pole-mounted switch. For example, the number of the pole-mounted switch, the location of the pole-mounted switch, etc.

[0032] By receiving the moisture detection request carrying the target pole-mounted switch identifier, it is helpful to accurately identify and locate the target pole-mounted switch that needs to be subjected to moisture detection. That is, through the target pole-mounted switch identifier, it is helpful to accurately find the target pole-mounted switch that needs to be detected among multiple pole-mounted switches, thereby ensuring the pertinence and accuracy of the detection process and improving the efficiency of determining the target pole-mounted switch.

[0033] S104. In response to the moisture detection request, control the power-on device to energize the target pole-mounted switch corresponding to the target pole-mounted switch identifier with a predetermined current to supply power to the corresponding line, where the predetermined current is a current with a predetermined frequency change;

[0034] In step S104 provided in this application, the moisture detection request is responded to, and the power-on device is controlled to energize the target pole-mounted switch corresponding to the target pole-mounted switch identifier with a predetermined current.

[0035] Among them, a power-on device is involved. The power-on device is a device used to apply current to the target pole-mounted switch and may include a power supply, a current controller, an interface connecting to the pole-mounted switch, etc.

[0036] Among them, a predetermined current is involved. The predetermined current is the current output by the power-on device and used to energize the target pole-mounted switch, and the predetermined current is a current with a predetermined frequency change.

[0037] Among them, a target pole-mounted switch is involved. The target pole-mounted switch is the pole-mounted switch corresponding to the target pole-mounted switch identifier and needs to be subjected to moisture detection.

[0038] By passing a current with a predetermined frequency change through the target pole-mounted switch, a changing magnetic field can be generated around the target pole-mounted switch. Thus, it provides a basis for subsequent induction of the target voltage based on this magnetic field change, which helps to subsequently induce the target voltage through the toroidal coil.

[0039] S106. When the target pole-mounted switch is energized, determine the target voltage corresponding to the toroidal coil, where the target pole-mounted switch passes through the toroidal coil;

[0040] In step S106 provided in the present application, when the switch on the target pole is powered on, the target voltage corresponding to the toroidal coil is determined.

[0041] Among them, a toroidal coil is involved, which is a ring-shaped coil wound by a wire. For example, the toroidal coil can be made by evenly winding the wire on a frame, and the frame can be a toroidal magnetic core.

[0042] The target voltage is a voltage signal induced by the annular coil, and the target voltage is generated by the influence of the predetermined current. For example, the target voltage is proportional to the change of the predetermined current in the switch on the target column.

[0043] When the switch on the target pole is energized, the target voltage corresponding to the toroidal coil is determined, and non-contact measurement can be achieved. This avoids the interference problem caused by direct current measurement, and converts the current change in the pole switch into a relatively more stable voltage signal with stronger anti-interference ability, thereby reducing the impact of external electromagnetic interference on the measurement results. The voltage signal induced by the toroidal coil can more sensitively detect slight changes in the insulation layer, thereby being able to more directly reflect the state of the insulation layer of the pole switch, and thus helping to achieve accurate detection of moisture.

[0044] S108, determining whether the switch on the target column is damp according to the target voltage.

[0045] In step S108 provided in the present application, a moisture result of whether the switch on the target column is damp is determined according to the target voltage.

[0046] The moisture result is determined based on the detected target voltage and is used to reflect the moisture state of the switch on the target column. The moisture result can be represented by the moisture level of the switch on the target column, the moisture index of the switch on the target column, etc.

[0047] By analyzing the moisture state of the switch on the target pole based on a relatively more stable and more anti-interference voltage signal, the influence of external electromagnetic interference on the measurement results can be reduced, solving the problem in the prior art that the current signal is easily affected by external interference and is difficult to directly reflect the moisture condition of the insulating layer of the switch on the pole, thereby helping to achieve accurate detection of the moisture state of the switch on the target pole.

[0048] Through the above steps S102 - S108, a moisture detection request is received. Among them, the target pole - mounted switch identifier is carried in the moisture detection request; in response to the moisture detection request, the energizing device is controlled to energize the target pole - mounted switch corresponding to the target pole - mounted switch identifier with a predetermined current to supply power to the corresponding line, where the predetermined current is a current with a predetermined frequency variation; when the target pole - mounted switch is energized, the target voltage corresponding to the toroidal coil is determined, where the target pole - mounted switch passes through the toroidal coil; based on the target voltage, the moisture result indicating whether the target pole - mounted switch is moisture - affected is determined. When detecting moisture in the pole - mounted switch, the predetermined current of the target pole - mounted switch is converted into a target voltage through the toroidal coil, which can achieve non - contact measurement. Moreover, by converting the current into voltage for analysis, the influence of external electromagnetic interference on the measurement result can be reduced, making the measurement result more reliable. And through the voltage signal induced by the toroidal coil, the minute changes in the insulating layer can be detected more sensitively, thus being able to more directly reflect the state of the insulating layer of the pole - mounted switch, and further solving the technical problem of inaccurate determination of the moisture - affected state when detecting moisture in the pole - mounted switch.

[0049] As an alternative embodiment, determining the target voltage corresponding to the toroidal coil includes: determining the conversion coefficient corresponding to the toroidal coil according to the coil parameters corresponding to the toroidal coil; determining the target current corresponding to the toroidal coil according to the predetermined current and the conversion coefficient; and determining the target voltage corresponding to the toroidal coil according to the target current.

[0050] In this embodiment, the specific steps for determining the target voltage corresponding to the toroidal coil are described.

[0051] Among them, coil parameters are involved. The coil parameters are parameters reflecting the physical characteristics, functional characteristics, etc. of the toroidal coil, and may include the number of turns of the toroidal coil, etc.

[0052] Among them, the conversion coefficient is involved. The conversion coefficient is a coefficient used to convert the predetermined current into the target current, and can be a proportional factor, which is used to reflect the conversion relationship between the predetermined current and the target current. For example, the conversion coefficient can be the reciprocal of the number of turns of the coil.

[0053] Among them, the target current is involved. The target current is the current generated in the toroidal coil due to the change in the magnetic field around the pole - mounted switch when the target pole - mounted switch passes through the predetermined current.

[0054] In the steps involved in this embodiment, first, according to the coil parameters corresponding to the toroidal coil, the conversion coefficient corresponding to the toroidal coil is determined. Then, according to the predetermined current and the conversion coefficient, the target current corresponding to the toroidal coil is determined. Finally, according to the target current, the target voltage corresponding to the toroidal coil is determined.

[0055] Through the above steps, based on the coil parameters of the toroidal coil, the induction ability and conversion ability of the toroidal coil to the current change in the on-pole switch can be accurately determined. Thus, according to the conversion coefficient obtained from the coil parameters and the predetermined current, the target current in the toroidal coil can be accurately determined, and further the accurate determination of the target voltage can be achieved.

[0056] As an alternative embodiment, determining the conversion coefficient corresponding to the toroidal coil includes: when the coil parameters include the number of turns of the coil, determining the conversion coefficient corresponding to the toroidal coil based on the number of turns of the coil, where the number of turns of the coil represents the number of turns of the coil (such as a wire) wound around the toroidal coil.

[0057] In this embodiment, the specific steps for determining the conversion coefficient corresponding to the toroidal coil are described.

[0058] Among them, the number of turns of the coil is involved. The number of turns of the coil is the number of turns of the coil (such as a wire) wound around the toroidal coil. The more the number of turns of the coil, the greater the induced electromotive force of the corresponding toroidal coil, and thus the higher the sensitivity of the toroidal coil to the current change.

[0059] In the steps involved in this embodiment, when the coil parameters include the number of turns of the coil, the conversion coefficient corresponding to the toroidal coil is determined according to the number of turns of the coil.

[0060] Through the above steps, by determining the number of turns of the coil, the sensitivity of the toroidal coil to the current change can be accurately reflected, which can help accurately quantify the conversion relationship between the predetermined current and the target current, improve the accuracy of determining the target current, and further help accurately determine the corresponding target voltage.

[0061] As an alternative embodiment, before controlling the power supply device to energize the target on-pole switch corresponding to the on-pole switch identification with a predetermined current, it further includes: determining the frequency response range corresponding to the toroidal coil; determining the predetermined current based on the frequency response range, where the frequency index corresponding to the predetermined current is within the frequency response range, and the on-pole switch is a switch connected to the columnar line.

[0062] In this embodiment, the specific steps before controlling the power supply device to energize the target on-pole switch corresponding to the on-pole switch identification with a predetermined current are described.

[0063] Among them, the frequency response range is involved. The frequency response range is the frequency change range corresponding to the current that the toroidal coil can effectively respond to.

[0064] Among them, the frequency index is involved. The frequency index is used to describe the signal frequency corresponding to the current.

[0065] In the steps involved in this embodiment, before controlling the energization device to energize the target post switch corresponding to the target post switch identifier with a predetermined current, first determine the frequency response range corresponding to the toroidal coil, and then determine the predetermined current based on the frequency response range.

[0066] By ensuring that the predetermined current is within the frequency response range before energizing the target post switch, it is possible to effectively avoid the situation where the toroidal coil cannot accurately reflect the true current state of the target post switch due to the frequency of the predetermined current being too high or too low, ensuring that the toroidal coil can accurately respond to the current change of the target post switch, thereby contributing to the accurate detection of the moisture state of the target post switch.

[0067] As an alternative embodiment, determining the frequency response range corresponding to the toroidal coil includes: determining the first resistance parameter, second resistance parameter, capacitance parameter, and current frequency response parameter corresponding to the toroidal coil, where the first resistance parameter is the resistance parameter of the resistance corresponding to the coil in the toroidal coil, and the second resistance parameter is the resistance parameter of the resistance externally connected to the coil in the toroidal coil; determining the frequency response lower limit corresponding to the toroidal coil based on the first resistance parameter, second resistance parameter, and current frequency response parameter; determining the frequency response upper limit corresponding to the toroidal coil based on the second resistance parameter and capacitance parameter; and determining the frequency response range corresponding to the toroidal coil based on the frequency response lower limit and the frequency response upper limit.

[0068] In this embodiment, the specific steps for determining the frequency response range corresponding to the toroidal coil are described.

[0069] Among them, the first resistance parameter is involved. The first resistance parameter is the resistance parameter of the resistance corresponding to the coil in the toroidal coil, which reflects the characteristics of the resistance of the coil itself in the toroidal coil. This first resistance parameter can be the internal resistance of the toroidal coil.

[0070] Among them, the second resistance parameter is involved. The second resistance parameter is the resistance parameter of the resistance externally connected to the coil in the toroidal coil, which reflects the characteristics of the additional resistance in the toroidal coil. This second resistance parameter can be a sampling resistance used to convert the current induced by the toroidal coil into a voltage signal.

[0071] Among them, the capacitance parameter is involved. The capacitance parameter is the parameter corresponding to the capacitance in the toroidal coil, which reflects the characteristics of the capacitance in the toroidal coil. For example, this capacitance parameter can be the stray capacitance of the toroidal coil, including the capacitance between the coil and the shielding layer and the capacitance between adjacent turns.

[0072] Among them, the current frequency response parameter is involved. The current frequency response parameter is a parameter used to reflect the response of the toroidal coil to current changes. The current frequency response parameter may include the self-inductance parameter and the mutual inductance parameter of the toroidal coil. Among them, the self-inductance parameter describes the reaction ability of the toroidal coil itself to the changing magnetic field. The larger the self-inductance parameter, the stronger the induction ability to current changes. The mutual inductance parameter describes the electromagnetic coupling strength between the toroidal coil and the switch on the target post, that is, the influence degree of the current change in the switch on the target post on the toroidal coil.

[0073] Among them, the lower limit of the frequency response is involved. The lower limit of the frequency response is the lowest frequency of the current in the switch on the target post that the toroidal coil can effectively respond to.

[0074] Among them, the upper limit of the frequency response is involved. The upper limit of the frequency response is the highest frequency of the current in the switch on the target post that the toroidal coil can effectively respond to.

[0075] In the steps involved in this embodiment, first, determine the first resistance parameter, the second resistance parameter, the capacitance parameter, and the current frequency response parameter corresponding to the toroidal coil. Then, according to the first resistance parameter, the second resistance parameter, and the current frequency response parameter, determine the lower limit of the frequency response corresponding to the toroidal coil. Next, according to the second resistance parameter and the capacitance parameter, determine the upper limit of the frequency response corresponding to the toroidal coil. Finally, according to the lower limit of the frequency response and the upper limit of the frequency response, determine the frequency response range corresponding to the toroidal coil.

[0076] By determining the lower limit of the frequency response, the lowest frequency that the toroidal coil can effectively respond to is clarified, and the upper limit of the frequency response clarifies the highest frequency that the toroidal coil can effectively respond to. Therefore, according to the lower limit and the upper limit of the frequency response, the frequency response range of the toroidal coil can be accurately determined, which helps to use toroidal coils with different frequency response ranges for moisture detection of switches on the post according to different measurement requirements, improving the adaptability and flexibility of moisture detection.

[0077] As an alternative embodiment, determining the moisture result of whether the switch on the target post is affected by moisture according to the target voltage includes: determining the amplitude characteristic value corresponding to the target voltage and determining the amplitude threshold corresponding to the switch on the target post; comparing the amplitude characteristic value corresponding to the target voltage with the amplitude threshold corresponding to the switch on the target post to obtain a comparison result; and determining the moisture result of whether the switch on the target post is affected by moisture according to the comparison result.

[0078] In this embodiment, the specific steps of determining the moisture result of whether the switch on the target post is affected by moisture according to the target voltage are described.

[0079] Among them, the amplitude characteristic value is involved. The amplitude characteristic value is used to quantify the strength of the voltage signal corresponding to the target voltage.

[0080] Among them, an amplitude threshold is involved. The amplitude threshold is preset and is the amplitude value of the voltage signal used to distinguish whether the on-pole switch is affected by moisture.

[0081] Among them, a comparison result is involved. The comparison result is obtained by comparing the amplitude characteristic value of the target voltage with the amplitude threshold. The comparison result can include three cases: the amplitude characteristic value is greater than, less than, or equal to the amplitude threshold, or it can be a specific quantization result, such as how much higher the amplitude characteristic value is than the amplitude threshold.

[0082] In the steps involved in this embodiment, first, the amplitude characteristic value corresponding to the target voltage is determined, and the amplitude threshold corresponding to the target on-pole switch is determined. Then, the amplitude characteristic value corresponding to the target voltage is compared with the amplitude threshold corresponding to the target on-pole switch to obtain a comparison result. Finally, based on the comparison result, the moisture result indicating whether the target on-pole switch is affected by moisture is determined.

[0083] By determining the amplitude characteristic value corresponding to the target voltage and the amplitude threshold, and then comparing the two, and judging whether the on-pole switch is affected by moisture according to the comparison result, a quantitative analysis of moisture detection is realized, which helps to accurately and efficiently identify the moisture state of the on-pole switch.

[0084] As an optional embodiment, after determining the moisture result indicating whether the target on-pole switch is affected by moisture based on the target voltage, it includes: in the case where the moisture result is that the target on-pole switch is affected by moisture, determining an operation instruction, where the operation instruction carries a target operation; sending the operation instruction to an execution device to control the execution device to perform the target operation.

[0085] In this embodiment, the specific steps after determining the moisture result indicating whether the target on-pole switch is affected by moisture based on the target voltage are described.

[0086] Among them, an operation instruction is involved. The operation instruction is determined according to the moisture result and is an instruction used to control the execution device to perform a specific operation. The operation instruction carries the target operation corresponding to the moisture result.

[0087] Among them, a target operation is involved. The target operation is a specific action or task for the execution device to perform, such as issuing an alarm, recording data, starting a maintenance program, cutting off the power supply, etc.

[0088] Among them, an execution device is involved. The execution device is a device that receives the operation instruction and performs the target operation. The execution device can be an alarm, a data recorder, etc.

[0089] In the steps involved in this embodiment, when the moisture absorption result is that the switch on the target pole is affected by moisture, an operation instruction corresponding to the moisture absorption result is determined, and the operation instruction carries a target operation, and the operation instruction is sent to the execution device to control the execution device to perform the target operation.

[0090] By determining and sending an operation instruction corresponding to the moisture absorption result when the moisture absorption result is that the switch on the target pole is affected by moisture, and controlling the execution device to perform the target operation according to the operation instruction, it realizes the timely response when the switch on the target pole is affected by moisture, without the need for manual intervention, which helps to take measures in the initial stage of moisture absorption, reduces the risk caused by response delay, and further helps to better protect the switch on the pole and related equipment, reduces the failures and maintenance costs caused by moisture, and improves the reliability and maintenance efficiency of the switch on the pole maintenance.

[0091] Based on the above embodiments and optional embodiments, an optional implementation manner is provided, which is specifically described below.

[0092] In the related art, when detecting whether the switch on the pole is affected by moisture by analyzing the current state in the switch on the pole, since the current is easily affected by external interference and the current signal is difficult to directly reflect the moisture absorption situation of the insulation layer of the switch on the pole, there is a technical problem that the determined moisture absorption state is inaccurate when detecting the moisture absorption of the switch on the pole.

[0093] For the above problems, no effective solutions have been proposed yet.

[0094] In view of this, in an optional implementation manner of the present invention, a method and device for detecting moisture absorption of a switch on a pole are provided, which can also be called a method and device for designing an integrated sensor of high-frequency pulse current and leakage current, and it can effectively solve the technical problem that the determined moisture absorption state is inaccurate when detecting the moisture absorption of the switch on the pole.

[0117] The calculation formula of the winding internal resistance is:

[0118]

[0119] Wherein:

[0120] R is the winding internal resistance (same as the above-mentioned first resistance parameter);

[0121] ρ is the resistivity of the coil winding material;

[0122] l is the winding length;

[0123] S is the cross-sectional area of the winding.

[0124] Based on the lumped-parameter equivalent circuit model of the electromagnetic induction type current sensor (same as the above-mentioned toroidal coil), the transfer function of the sensor can be derived as:

[0125]

[0126] Wherein:

[0127] H(jω) is used to represent the frequency response relationship, that is, the relationship between the output voltage and the input current;

[0128] j is the imaginary unit, used to represent the phase of the sinusoidal quantity;

[0129] ω is the angular frequency;

[0130] U2 is the target voltage;

[0131] R s is the sampling resistance (same as the above-mentioned second resistance parameter);

[0132] C0 is the stray capacitance of the toroidal coil (same as the above-mentioned capacitance parameter), which includes two parts: the stray capacitance value between the toroidal coil and the shielding layer and the stray capacitance value between adjacent turns.

[0133] The formula for the amplitude-frequency characteristic of the sensor is as follows:

[0134]

[0135] The amplitude-frequency characteristic of the sensor can also be expressed as:

[0136]

[0137] Wherein:

[0138] |H(jω)| represents the amplitude-frequency characteristic of the sensor.

[0139] According to the formula for the amplitude-frequency characteristic of the sensor, the formula for the cut-off frequency of the core coil can be obtained. Among them, the low-frequency cut-off frequency f L (same as the above-mentioned lower limit of the frequency response) is the lower limit frequency for the self-integration condition to hold, and the high-frequency cut-off frequency f HThe calculation of (the same as the above upper limit of frequency response) needs to consider the influence of the stray capacitance parameter C0 of the sensor. The equivalent circuit is similar to the parallel resonance circuit of high-frequency signals, and the cut-off frequency can be expressed as the sampling resistance R s and the resonance frequency of the parallel circuit of the stray capacitance C0.

[0140] The formula for the low-frequency cut-off frequency is as follows:

[0141]

[0142] Where:

[0143] f L represents the low-frequency cut-off frequency of the sensor (the same as the above lower limit of frequency response).

[0152] represents the sensitivity;

[0153] BW represents the working frequency band.

[0154] To broaden the working frequency band of the sensor, the low-frequency cut-off frequency of the sensor should be reduced as much as possible, and the high-frequency cut-off frequency should be increased; the bandwidth BW of the sensor can be broadened by reducing the sampling resistance R s , the stray capacitance C0, the internal resistance R of the coil winding, and increasing the self-inductance L of the coil.

[0155] S22, determine the predetermined current according to the frequency response range, where the frequency index corresponding to the predetermined current is within the frequency response range;

[0156] S23, control the energized device to energize the target pole-mounted switch corresponding to the target pole-mounted switch identification with the predetermined current to supply power to the corresponding line, where the predetermined current is a current that changes with the predetermined frequency.

[0157] For example, by evenly winding an enameled wire (the same as the above-mentioned coil) around a bobbin, a corresponding toroidal coil is obtained. When measuring the current, the measured current (the same as the above-mentioned predetermined current) is made to perpendicularly pass through the center of the toroidal plane of the toroidal coil. The primary side of the toroidal coil is the measured wire (the same as the above-mentioned switch on the target post), the secondary side is the coil on the bobbin, and the load on the secondary side is a very small sampling resistor (the same as the resistor externally connected to the coil).

[0158] When a varying current (the same as the above-mentioned predetermined current) flows through the measured wire, a magnetic field signal that changes with the current will be generated around the wire. According to the principle of electromagnetic induction, the changing magnetic field will induce an electromotive force in the uniformly wound coil, which is sampled by the secondary load.

[0159] S3. With the switch on the target post energized, determine the target voltage corresponding to the toroidal coil, where the switch on the target post passes through the toroidal coil;

[0160] Specifically, S3 further includes:

[0161] S31. When the coil parameters include the number of turns of the coil, determine the conversion coefficient corresponding to the toroidal coil based on the number of turns of the coil, where the number of turns of the coil represents the number of turns of the coil wound around the toroidal coil;

[0162] S32. Determine the target current corresponding to the toroidal coil based on the predetermined current and the conversion coefficient;

[0163] S33. Determine the target voltage corresponding to the toroidal coil based on the target current.

[0164] For example, under the action of the sampling resistor R s , the secondary-side current i2 (the same as the above-mentioned target current) is converted into U2 (the same as the above-mentioned target voltage) for measurement, and the output voltage of the core coil can be obtained as follows:

[0165]

[0166] Where:

[0167] i2 is the target current;

[0168] 1 / N is the conversion coefficient.

[0169] S4. Determine the amplitude characteristic value corresponding to the target voltage and determine the amplitude threshold corresponding to the switch on the target post;

[0170] S5. Compare the amplitude characteristic value corresponding to the target voltage with the amplitude threshold corresponding to the switch on the target post to obtain a comparison result;

[0171] S6. Determine the moisture-affected result of whether the switch on the target post is affected by moisture based on the comparison result;

[0172] S7. When the moisture absorption result indicates that the switch on the target pole is affected by moisture, determine an operation instruction, where the operation instruction carries a target operation;

[0173] S8. Send the operation instruction to an execution device to control the execution device to perform the target operation.

[0174] (2) Moisture detection device for switches on poles:

[0175] This moisture detection device mainly consists of four parts: a current sensor, a data processor, an insulating rod, and a remote controller.

[0176] Among them:

[0177] The current sensor is used to collect current signals and convert the current signals into voltage signals. A magnetic ring is provided at the head end of the current sensor;

[0178] The data processor is used to process voltage signals and analyze whether the switch on the pole is affected by moisture;

[0179] The insulating rod is used to support the current sensor and the data processor;

[0180] The remote controller is used to control the opening and closing of the iron core at the head end of the current sensor.

[0181] For example, the moisture detection device for switches on poles can be a sensor integrating high-frequency pulse current and leakage current. The head end of this sensor can be freely opened and closed. By clamping the sensor on the grounding wire of the switch on the pole, it can simultaneously detect the high-frequency pulse current signal and the low-frequency insulation leakage current signal flowing through the grounding wire of the switch on the pole (the same as the above-mentioned target switch on the pole). Among them, the power frequency partial discharge detection range is 0 - 10 mA, and the test accuracy is not lower than 1 mA ± 5%; the high-frequency current detection frequency band is not lower than 30 MHz.

[0182] The current sensor (the same as the above-mentioned toroidal coil) in this moisture detection device for switches on poles can control the opening and closing of the magnetic ring at the head end through a built-in electric push rod. Through on-site remote control operation, it is sleeved on the grounding lead-down wire of the switch on the pole, and can simultaneously detect the low-frequency insulation leakage current and the high-frequency partial discharge pulse current signal. Considering that the current signal of the grounding wire is relatively weak, the magnetic core is selected as a nanocrystalline material with good low-frequency magnetic conductivity and low high-frequency loss. Among them, the size of the magnetic core used is: the outer diameter of the magnetic ring is 90.75 mm, the inner diameter is 60.25 mm, and the height is 15.4 mm.

[0183] For the determination of the number of turns of the coil, as can be seen from the foregoing formula, with the increase of the number of turns N of the coil, the self-inductance L of the coil will increase, which will cause the low-frequency cut-off frequency of the coil response to decrease, and at the same time, the linearity and stability will become better. However, at the same time, the increase of the number of turns N of the coil will increase the stray capacitance C0 of the coil, resulting in the decrease of the high-frequency cut-off frequency.

[0184] When the number of turns of the coil is fixed, increasing the resistance value of the sampling resistor can improve the sensitivity, but the working frequency band of the coil will be correspondingly reduced. Therefore, two kinds of magnetic cores with 600 turns and 1200 turns (the same as the above-mentioned toroidal coil) were customized for testing. Enameled wire with a cross-sectional area of 0.15 square millimeters was used to wind two layers and three layers respectively, with 300 turns per layer, and the parameters of the toroidal coil were measured to obtain: R = 173.47 Ω, L = 2613.4 mH.

[0185] In addition, aluminum alloy is selected as the key material for the shielding layer, aiming to significantly reduce the interference effect of the magnetic field induced by the phase current on the function of the high-frequency current measurement part of the integrated sensor. The magnetic core is surrounded by two layers of aluminum shells. The magnetic core is painted with insulating paint or padded with insulating materials to avoid direct contact with the aluminum shells.

[0186] This current sensor can be a non-contact through-type current sensor, which is designed based on the basic principle of the Rogowski coil. The measurement principle of the Rogowski coil is based on the electromagnetic induction principle and Ampere's circuital law.

[0187] The data processor in this on-pole switch moisture detection device includes: a central processing unit (such as a Raspberry Pi), a four-channel very high frequency (VHF) acquisition board, an 80WH built-in lithium battery, and a 4G network card.

[0188] Among them:

[0189] The four-channel VHF acquisition board is used to collect the leakage current and high-frequency pulse current data flowing through the grounding wire of the on-pole switch;

[0190] The 80WH built-in lithium battery is used to supply power to the Raspberry Pi and the four-channel VHF acquisition board;

[0191] The 4G network card is used to provide network connection for the Raspberry Pi;

[0192] The central processing unit (such as a Raspberry Pi) is used for processing and analyzing the collected data.

[0193] The remote controller in this on-pole switch moisture detection device includes an open button, a pause button, and a close button, which are used to control the opening and closing of the magnetic core at the head end of the current sensor.

[0194] The insulating rod is used to support the current sensor and the data processor, and the length of the insulating rod can be changed by telescoping.

[0195] During on-site testing, the battery sensor is controlled to open and close through the remote controller, and it is sleeved on the grounding wire of the on-pole switch to detect the insulation condition of the on-pole switch.

[0196] Through this high-frequency pulse current and leakage current integrated sensor, the sensor can be controlled by a remote control to open and close the sleeve on the pole switch grounding wire, detect the low-frequency leakage current and high-frequency partial discharge pulse current flowing in the pole switch grounding wire, and realize the coordinated judgment of the internal moisture defects of the pole switch equipment based on the leakage current and broadband pulse signal. It does not require high-voltage operation and is less dangerous.

[0197] Through the above optional implementation, at least the following beneficial effects can be achieved:

[0198] (1) Compared with the related art, the present invention can realize non-contact measurement by converting the predetermined current of the target pole switch into the target voltage through the ring coil when detecting moisture on the pole switch, and by converting the current into voltage for analysis, the measurement result can be made more reliable and the influence of external electromagnetic interference on the measurement result can be reduced. The voltage signal induced by the ring coil can more sensitively detect slight changes in the insulation layer, so as to more directly reflect the state of the insulation layer of the pole switch, thereby solving the technical problem of inaccurate determination of the moisture state when detecting moisture on the pole switch.

[0199] (2) Compared with the related art, the present invention can accurately determine the sensing ability and conversion ability of the ring coil to the current change in the switch on the target pole according to the coil parameters of the ring coil, so that the target current in the ring coil can be accurately determined according to the conversion coefficient obtained from the coil parameters and the predetermined current, thereby achieving accurate determination of the target voltage.

[0200] (3) Compared with the related art, the present invention comprehensively evaluates the current frequency response state by integrating the first resistance parameter, the second resistance parameter, the capacitance parameter and the current frequency response parameter of the ring coil in the detection of moisture on the pole-mounted switch, and determines the frequency response range accordingly, thereby improving the accuracy of determining the corresponding voltage, and further facilitating the accurate detection of moisture on the pole-mounted switch.

[0201] (4) Compared with the related art, the present invention fills the gap in the detection of moisture inside the existing pole-mounted switches, and is universal for pole-mounted switches of different regions and models. The detection method is simple, fast and easy to operate, which helps to solve the problem of failure caused by moisture inside the pole-mounted switches.
