如图1所示，一种适用于空心电抗器的质量检测装置，质量检测装置包括依次连接的输入装置、采集装置、计算装置、判断装置、及分类装置；其中，As shown in FIG. 1, a quality detection device suitable for an air-core reactor, the quality detection device includes an input device, a collection device, a calculation device, a judgment device, and a classification device connected in sequence; wherein,
输入装置与高频电流发生器连接以用于向空心电抗器中输入预设频率的高频电流以测定在通过高频电流后空心电抗器的目标信息；The input device is connected with the high-frequency current generator for inputting a high-frequency current of a preset frequency into the air-core reactor to determine the target information of the air-core reactor after passing the high-frequency current;
采集装置用于在预设周期内采集空心电抗器的目标信息；The acquisition device is used to acquire target information of the air-core reactor within a preset period;
计算装置用于基于采集装置采集到的目标信息计算目标参数；The computing device is used to calculate the target parameter based on the target information collected by the collecting device;
判断装置用于基于计算装置中获得的目标参数，确定空心电抗器质量是否合格；The judging device is used to determine whether the quality of the air-core reactor is qualified based on the target parameters obtained in the computing device;
分类装置根据判断装置的判断结果，对确定质量合格的空心电抗器根据预设阈值范围进行分类。The classification device classifies the air-core reactors whose quality is determined to be qualified according to the judgment result of the judgment device according to the preset threshold range.
具体地，其中，采集装置所采集的空心电抗器的目标信息包括在预设周期内不同时间点的空心电抗器的线径温度Ti和空心电抗器的电导率Ii。Specifically, the target information of the air-core reactor collected by the collecting device includes the wire diameter temperature Ti of the air-core reactor and the electrical conductivity Ii of the air-core reactor at different time points in a preset period.
具体地，计算装置计算出的目标参数为预设周期内针对多个时间点的空心电抗器的电导率Ii与空心电抗器的线径温度Ti的比值Ki的平均差，其中Ki=Ii/Ti，Specifically, the target parameter calculated by the computing device is the average difference of the ratio Ki of the electrical conductivity Ii of the air-core reactor and the wire diameter temperature Ti of the air-core reactor for multiple time points in a preset period, where Ki=Ii/Ti ,
Ii为对应于时间点i采集到的空心电抗器对应的电导率，单位为S/m；Ii is the conductivity corresponding to the air-core reactor collected at time point i, in S/m;
Ti为对应于时间点i采集到的空心电抗器的线径温度，单位为℃/m；Ti is the wire diameter temperature of the air-core reactor collected corresponding to time point i, and the unit is °C/m;
Ki为对应于时间点i时 Ii和Ti的比值，单位为S/℃，Ki is the ratio of Ii to Ti corresponding to time point i, in S/°C,
i为预设周期内的第i个时间点，作为优选，预设周期内多个时间点的选取可以根据实际质量检测的需求选取预设周期内将预设周期等分的对应的时间点（例如预设周期选取为5h，则可以选取将预设周期5h等分为5段的各个时间点）。i is the i-th time point in the preset period. Preferably, the selection of multiple time points in the preset period can be based on the actual quality inspection requirements to select the corresponding time points in the preset period that divide the preset period into equal parts ( For example, the preset period is selected as 5h, then the preset period of 5h can be selected to be equally divided into 5 time points).
具体地，判断装置中预设有目标参数阈值，当且仅当计算装置中计算出的目标参数超过目标参数阈值时，认定空心电抗器质量不合格；当且仅当计算装置中计算出的目标参数不超过目标参数阈值时，认定空心电抗器质量合格，作为进一步的优选，该预设的目标参数阈值能够调节，且根据待检测的空心电抗器的种类不同而不同，且在多次对同一种类和同一型号的空心电抗器进行质量检测后，对与该空心电抗器所对应的目标参数阈值进行修正。Specifically, a target parameter threshold is preset in the judging device, if and only if the target parameter calculated in the computing device exceeds the target parameter threshold, the quality of the air-core reactor is determined to be unqualified; if and only if the target parameter calculated in the computing device is unqualified; When the parameter does not exceed the target parameter threshold, it is determined that the quality of the air-core reactor is qualified. As a further preference, the preset target parameter threshold can be adjusted and is different according to the type of the air-core reactor to be detected. After the quality inspection of the air-core reactor of the same type and the same type, the target parameter threshold corresponding to the air-core reactor is corrected.
具体地，分类装置中预设有第一评价等级区间、第二评价等级区间、及第三评价等级区间，当计算装置计算出的目标参数位于第一评价等级区间时，认定空心电抗器质量为优；当计算装置计算出的目标参数位于第二评价等级区间时，认定空心电抗器质量为良；当计算装置计算出的目标参数位于第三评价等级区间时，认定空心电抗器质量为一般，从而在确定空心电抗器质量是否合格后对质量合格的空心电抗器实现产品质量的评级。Specifically, a first evaluation grade interval, a second evaluation grade interval, and a third evaluation grade interval are preset in the classification device. When the target parameter calculated by the computing device is located in the first evaluation grade interval, it is determined that the quality of the air-core reactor is Excellent; when the target parameter calculated by the computing device is located in the second evaluation level interval, the quality of the air-core reactor is determined to be good; when the target parameter calculated by the computing device is located in the third evaluation level interval, the quality of the air-core reactor is determined to be average, Therefore, after determining whether the quality of the air-core reactor is qualified, the product quality rating of the qualified air-core reactor is realized.
具体地，第三评价等级区间的上限值等于目标参数阈值，第三评价等级区间的下限值等于第二评价等级区间的上限值；第二评价等级区间的下限值等于第一评价等级区间的上限值，从而以目标参数阈值作为评价空心电抗器是否合格的标准线，当超出目标参数阈值时，认定空心电抗器质量不合格，当不超出目标参数阈值时，越靠近目标参数阈值，空心电抗器的质量评级越低，越远离目标参数阈值，空心电抗器的质量评级越高。Specifically, the upper limit of the third evaluation level interval is equal to the target parameter threshold, the lower limit of the third evaluation level interval is equal to the upper limit of the second evaluation level interval; the lower limit of the second evaluation level interval is equal to the first evaluation The upper limit of the grade interval, so the target parameter threshold is used as the standard line for evaluating whether the air-core reactor is qualified. When the target parameter threshold is exceeded, the quality of the air-core reactor is determined to be unqualified. When the target parameter threshold is not exceeded, the closer to the target parameter Threshold, the lower the quality rating of the air-core reactor, the farther away from the target parameter threshold, the higher the quality rating of the air-core reactor.
具体地，本发明还提供一种适用于空心电抗器的质量检测方法，包括以下步骤：Specifically, the present invention also provides a quality detection method suitable for an air-core reactor, comprising the following steps:

3）计算装置基于采集装置采集到的位于不同时间点的空心电抗器的线径温度Ti和空心电抗器的电导率Ii计算对应于当前第i个时间点的比值Ki，其中Ki=Ii/Ti，3) The computing device calculates the ratio Ki corresponding to the current i-th time point based on the wire diameter temperature Ti of the air-core reactor at different time points and the electrical conductivity Ii of the air-core reactor collected by the acquisition device, where Ki=Ii/Ti ,

6）当认定空心电抗器质量合格后，分类装置将目标参数与预设的各评价等级区间的对比，当计算装置计算出的目标参数位于第一评价等级区间时，认定空心电抗器质量为优；当计算装置计算出的目标参数位于第二评价等级区间时，认定空心电抗器质量为良；当计算装置计算出的目标参数位于第三评价等级区间时，认定空心电抗器质量为一般；6) When the quality of the air-core reactor is determined to be qualified, the classification device compares the target parameters with the preset evaluation grade intervals. When the target parameters calculated by the computing device are located in the first evaluation grade interval, the quality of the air-core reactor is determined to be excellent. ; When the target parameter calculated by the computing device is located in the second evaluation level interval, it is determined that the quality of the air-core reactor is good; When the target parameter calculated by the computing device is located in the third evaluation level interval, it is determined that the quality of the air-core reactor is normal;
且其中，第三评价等级区间的上限值等于目标参数阈值，第三评价等级区间的下限值等于第二评价等级区间的上限值；第二评价等级区间的下限值等于第一评价等级区间的上限值。And among them, the upper limit value of the third evaluation level interval is equal to the target parameter threshold, the lower limit value of the third evaluation level interval is equal to the upper limit value of the second evaluation level interval; the lower limit value of the second evaluation level interval is equal to the first evaluation level. The upper limit of the class interval.
作为优选，如果空心电抗器存在绝缘漏电的风险，则空心电抗器从输入预设频率的高频电流起，其初始线径温度升温至预设线径温度的时间段相对于正常空心电抗器会延长。因此，作为另一优选实施方式，Preferably, if the air-core reactor has the risk of insulation leakage, the time period during which the initial wire diameter temperature of the air-core reactor is raised to the preset wire diameter temperature from the input of the high-frequency current of the preset frequency will be longer than that of the normal air-core reactor. extend. Therefore, as another preferred embodiment,
