[0031] While the following description provides many specific details to fully understand this disclosure, it is also possible to implement this disclosure in ways other than those described herein, and obviously the examples described in the specification are only a selection of the examples of this disclosure and do not encompass all examples.
[0032] The following describes, with reference to the drawings, the withstand voltage test circuit, method, apparatus, equipment, and memory medium of the equipment according to the embodiments of this disclosure.
[0033] Figure 1 is a schematic diagram showing the structure of a withstand voltage test circuit of equipment provided by an embodiment of the present disclosure, and as shown in Figure 1, the withstand voltage test circuit of the equipment includes a voltage regulation module, a protection module, and a high-voltage module.
[0034] To facilitate understanding of the embodiments of this disclosure, a schematic diagram of the structure of a withstand voltage test circuit for equipment including a voltage regulating module, a protection module, and a high-voltage module, shown in Figure 1, is given as an example, where the voltage regulating module 10 and the protection module 20 are connected in parallel, the protection module 20 and the high-voltage module 30 are connected in parallel, the test electrical equipment 40 and the high-voltage module 30 are connected in parallel, the voltage regulating module 10 is used to adjust the voltage input to the test electrical equipment 40, the protection module 20 is used to control the current input to the test electrical equipment 40, and the high-voltage module 30 is used to measure the resonance point of the test electrical equipment 40 and generate a high voltage based on the resonance point, where the voltage at the resonance point is the highest.
[0035] The resonance point refers to a specific frequency point in a withstand voltage test circuit where the impedance values of the inductance (inductive reactance) and capacitance (capacitive reactance) of a high-voltage module are equal. In AC circuits, the impedance of an inductance is proportional to the frequency, and the impedance of a capacitor is inversely proportional to the frequency. When the impedance values of both are equal, the circuit reaches a resonant state. At this point, the total impedance of the circuit is at its minimum, the current is at its maximum, and in a series resonant circuit, the voltage reaches its highest value.
[0036] In withstand voltage testing, finding the resonance point is crucial because it allows the highest voltage to be applied to the test electrical equipment, thereby effectively testing its withstand voltage performance. By adjusting the inductance and capacitance values in the circuit, the frequency of the resonance point can be changed, making it possible to accommodate the withstand voltage testing requirements of different test electrical equipment.
[0037] A withstand voltage test circuit for equipment provided by this disclosure includes a voltage regulating module, a protection module, and a high-voltage module, wherein the voltage regulating module and the protection module are connected in parallel, the protection module and the high-voltage module are connected in parallel, the test electrical equipment and the high-voltage module are connected in parallel, the voltage regulating module is used to regulate the voltage input to the test electrical equipment, the protection module is used to control the current input to the test electrical equipment, and the high-voltage module is used to measure the resonance point of the test electrical equipment and generate a high voltage based on the resonance point, where the voltage at the resonance point is the highest. Compared to related technologies, because the withstand voltage test circuit for equipment is connected in parallel, when the withstand voltage test circuit for equipment reaches the resonance point, the total impedance of the withstand voltage test circuit for equipment becomes the minimum value, and if the total impedance of the withstand voltage test circuit for equipment is monitored to be the minimum value, the resonance point can be found, and therefore the resonance point can be easily identified in a withstand voltage test circuit for equipment connected in parallel, and the difficulty of withstanding voltage testing of electrical equipment is further reduced.
[0038] In some embodiments, continuing to refer to Figure 1, the voltage regulation module 10 includes a voltage regulator 101 and a transformer 102. The voltage regulator 101 and the transformer 102 are connected in series, and the transformer 102 and the protection module 20 are connected in parallel.
[0039] The primary function of a voltage regulator is to regulate voltage. In a withstand voltage test circuit, a voltage regulator is used to adjust the voltage level input to the test electrical equipment. By changing the settings of the voltage regulator, the voltage applied to the test equipment can be precisely controlled, and various operating conditions or test requirements can be simulated. This is crucial for ensuring the accuracy and effectiveness of the test, as it allows the test operator to apply a specific voltage level as needed. A transformer is an electrical device used to change voltage and operates on the principle of electromagnetic induction. In a withstand voltage test circuit, a transformer is connected in series with a voltage regulator to further regulate the voltage. A transformer can increase or decrease the voltage depending on the specific requirements of the test. In withstand voltage testing, transformers are typically used to increase the voltage to a predetermined test level, or, in some cases, to decrease the voltage for the purpose of conducting a safer test. Transformers can also provide electrical isolation, that is, they can improve safety by providing insulation between the primary and secondary sides, which is particularly noticeable when dealing with high voltages.
[0040] By connecting a voltage regulator and a transformer in series, they can work together to regulate voltage. The voltage regulator first pre-regulates the input voltage and can flexibly change the output voltage within a certain range. This pre-regulated voltage then functions as the input voltage for the transformer. The transformer further modifies the voltage based on its turns ratio. For example, if the voltage regulator steps down or steps up the input commercial power voltage (e.g., 220V) to an intermediate value, the transformer can convert this intermediate voltage to a value close to the withstand voltage test voltage required by the electrical equipment being tested, according to its own transformation ratio. This series connection method enables a more precise and wider voltage regulation range, allowing it to meet the testing requirements of electrical equipment with different withstand voltage levels.
[0041] In some embodiments, continuing with reference to Figure 1, the protection module 20 includes a first resistor 201, a second resistor 202, and a sphere gap 203. The first resistor 201 and the voltage adjustment module 10 are connected in series, the first resistor 201 and the second resistor 202 are connected in parallel, the second resistor 202 and the sphere gap 203 are connected in series, the sphere gap 203 and the voltage adjustment module 10 are connected in parallel, the first resistor 201 and the high-voltage module 30 are connected in parallel, the second resistor 202 and the high-voltage module 30 are connected in parallel, and the sphere gap 203 and the high-voltage module 30 are connected in parallel.
[0042] The first resistor is a component of the protection module, connected in series with the voltage regulation module, meaning it is located between the voltage regulation module and the protection module, and is used to limit current. When current flows through the first resistor, the resistor consumes some power, thereby reducing the current flowing through the subsequent circuit. Furthermore, the first resistor is connected in parallel with the second resistor, forming a shunt path that helps distribute current between different circuit parts. The second resistor is also part of the protection module, connected in parallel with the first resistor and in series with the sphere gap. The role of the second resistor is to provide another current limiting and shunt path. In a parallel circuit, the second resistor helps to share the current load of the first resistor, thereby preventing the circuit from being damaged by excessive current. The sphere gap is a protective device, usually consisting of two or more spherical electrodes with a certain gap between them. The main role of the sphere gap is to provide protection in the event of an overvoltage condition. If the voltage exceeds the design threshold of the sphere gap, an arc discharge occurs in the sphere gap, causing it to break down. As a result, current can flow, protecting the circuit by allowing the release of overvoltage energy. The sphere gap is connected in parallel with the first and second resistors, meaning that under normal operating conditions, current mainly flows through the resistors, and under overvoltage conditions, the sphere gap activates to provide protection.
[0043] In the protection module, by connecting the first resistor, the second resistor, and the sphere gap in parallel, the resonance point can be precisely measured without interfering with voltage regulation.
[0044] In some embodiments, continuing to refer to Figure 1, the high-voltage module 30 includes a reactor 301, a first capacitor 302, a second capacitor 303, and a voltmeter 304. The reactor 301 and the protection module 20 are connected in parallel, the reactor 301 and the test electrical equipment 40 are connected in parallel, the test electrical equipment 40 and the first capacitor 302 are connected in parallel, the first capacitor 302 and the second capacitor 303 are connected in series, the second capacitor 303 and the test electrical equipment 40 are connected in parallel, and the voltmeter 304 and the second capacitor 303 are connected in parallel.
[0045] Reactors are used to limit current or adjust the phase of a circuit. Their function is to control the flow of current in an AC circuit by providing inductive reactance through the action of inductance. In withstand voltage test circuits, reactors are connected in parallel with protective modules and test electrical equipment and are primarily used to regulate current and voltage, thereby preventing excessive current during the test process and contributing to the formation of resonant conditions.
[0046] The first capacitor is one of the capacitors in the withstand voltage test circuit and is connected in parallel with the test electrical equipment. The role of the first capacitor is to store power and provide capacitive reactance to the circuit. It is connected in series with the second capacitor and contributes to the formation of a resonant circuit, thereby enabling the generation of a high voltage at the resonant point. By adjusting the capacitance value, the resonant frequency of the circuit can be affected, and the effectiveness of the withstand voltage test can be optimized.
[0047] The second capacitor is also a capacitor in a voltage test circuit, typically connected in series with the first capacitor and in parallel with the test electrical equipment. Like the first capacitor, the second capacitor's role is primarily to store power and provide capacitive reactance. Under resonant conditions, the second capacitor works in conjunction with the first capacitor to help the circuit reach its resonant point and generate the highest voltage.
[0048] A voltmeter is a measuring instrument used to measure the voltage in a circuit. In a withstand voltage test circuit, the voltmeter is connected in parallel with the second capacitor and is primarily used to monitor the voltage value of the second capacitor in real time. By measuring the value displayed on the voltmeter, the voltage level at which the circuit is at its resonance point can be obtained, thereby allowing evaluation of the withstand voltage performance of the test electrical equipment.
[0049] By monitoring the capacitive reactance values of the first and second capacitors, as well as the inductive reactance value of the reactor, the conditions under which the circuit reaches its resonance point can be precisely determined. At the resonance point, the voltage value of the first capacitor can be calculated based on the voltage and capacitance values of the second capacitor, and this voltage value represents the withstand voltage of the test electrical equipment.
[0050] According to embodiments of the present disclosure, the present disclosure further provides a method for testing equipment withstand voltage, as shown in Figure 2, which is a flowchart of the method for testing equipment withstand voltage provided by embodiments of the present disclosure, the method being applied to a withstand voltage test circuit for equipment and comprising the following steps 501 to 504.
[0051] Step 501: The first capacitive reactance value of the first capacitor and the second capacitive reactance value of the second capacitor in the high-voltage module of the equipment's withstand voltage test circuit are monitored, and the inductive reactance value of the reactor in the high-voltage module is monitored, and the equipment's withstand voltage test circuit and the test electrical equipment are connected in parallel.
[0052] The formula for calculating the capacitive reactance value can be realized by equation (1).
[0053] TIFF2026114938000002.tif14170 Here, TIFF2026114938000003.tif5170 is a capacitive reactance value, TIFF2026114938000004.tif6170 is the frequency of AC power, TIFF2026114938000005.tif5170 is the capacitance value of a capacitor.
[0054] The formula for calculating the inductive reactance value can be realized by equation (2).
[0055] TIFF2026114938000006.tif10170 Here, TIFF2026114938000007.tif6170 is an inductive reactance value, TIFF2026114938000008.tif6170 is the frequency of AC power, TIFF2026114938000009.tif5170 is the inductance value of the reactor.
[0056] By monitoring the capacitive reactance of the capacitor and the inductive reactance of the inductor, it is possible to determine whether or not the circuit will reach its resonance point. At the resonance point, the sum of the inductive reactance of the inductor and the capacitive reactance of the capacitor becomes equal, at which point the total impedance of the circuit is at its minimum and the voltage reaches its maximum.
[0057] Step 502: When the sum of the inductive reactance value and the capacitive reactance value is equal, it is determined that the withstand voltage test circuit of the equipment has reached its resonance point, and the sum of the capacitive reactance values is the sum of the first capacitive reactance value and the second capacitive reactance value.
[0058] By adjusting the frequency of the AC current until the sum of the inductive reactance and capacitive reactance values is equal, and conducting the test at the resonance point, the insulation performance and high-voltage environmental resistance of electrical equipment can be evaluated more accurately, thereby improving the accuracy of the withstand voltage test.
[0059] Step 503: If it is determined that the withstand voltage test circuit of the equipment has reached the resonance point, the voltage value of the second capacitor is obtained, and the first capacitance value of the first capacitor and the second capacitance value of the second capacitor are obtained.
[0060] The capacitance values of the first and second capacitors are typically preset parameters and can be determined during the circuit design phase based on test requirements and circuit configuration.
[0061] Step 504: Based on the voltage value of the second capacitor, the first capacitance value, and the second capacitance value, the voltage value of the first capacitor is calculated, and the voltage value of the first capacitor is determined as the withstand voltage value of the test electrical equipment.
[0062] The formula for calculating the voltage value of the first capacitor can be realized by formula (3).
[0063] TIFF2026114938000010.tif14170 Here, TIFF2026114938000011.tif5170 is the voltage value of the first capacitor, TIFF2026114938000012.tif5170 is the voltage value of the second capacitor, TIFF2026114938000013.tif5170 is the first volume value, TIFF2026114938000014.tif5170 is the second volume value.
[0064] In actual power system operation, electrical equipment faces a variety of complex voltage conditions. The withstand voltage values determined by this calculation method can simulate the tolerance capability of electrical equipment in overvoltage conditions that may occur.
[0065] A method for withstanding voltage testing of equipment provided by this disclosure includes a voltage regulating module, a protection module, and a high-voltage module, wherein the voltage regulating module and the protection module are connected in parallel, the protection module and the high-voltage module are connected in parallel, the test electrical equipment and the high-voltage module are connected in parallel, the voltage regulating module is used to regulate the voltage input to the test electrical equipment, the protection module is used to control the current input to the test electrical equipment, and the high-voltage module is used to measure the resonance point of the test electrical equipment and generate a high voltage based on the resonance point, where the voltage at the resonance point is the highest. Compared to related technologies, since the withstanding voltage test circuit of equipment is connected in parallel, when the withstanding voltage test circuit of equipment reaches the resonance point, the total impedance of the withstanding voltage test circuit of equipment becomes the minimum value, and if the total impedance of the withstanding voltage test circuit of equipment is monitored to be the minimum value, the resonance point can be found, and therefore the resonance point can be easily identified in a withstanding voltage test circuit of equipment connected in parallel, and the difficulty of withstanding voltage testing of electrical equipment is further reduced.
[0066] As an implementation of step 504, calculating the voltage value of the first capacitor based on the voltage value of the second capacitor, the first capacitance value, and the second capacitance value described above can be achieved using the following method, namely, performing a quotient calculation between the first capacitance value and the second capacitance value, obtaining the quotient result, and then performing a product calculation between the voltage value of the second capacitor and the quotient result to obtain the voltage value of the first capacitor, but is not limited to this method.
[0067] Specifically, the implementation process of this embodiment is structured as a literal description of equation (3).
[0068] Based on the above, the embodiments of this disclosure can achieve the following effects: Since the withstand voltage test circuits of the equipment are connected in parallel, when the withstand voltage test circuits reach their resonance point, the total impedance of the withstand voltage test circuits becomes minimum. By monitoring that the total impedance of the withstand voltage test circuits is at its minimum, the resonance point can be found. Therefore, the resonance point can be easily identified in withstand voltage test circuits of equipment connected in parallel, and the difficulty of withstanding voltage testing of electrical equipment is further reduced.
