Description

Technical Field

[0001] This utility model relates to the field of capacitor production technology, specifically to an aging device for testing bushing capacitors with automatic high current setting. Background Technology

[0002] Aging testing is a crucial step in the production and quality inspection of aluminum electrolytic capacitors. Traditional aging equipment for testing bushing capacitors has several problems. When testing different models of aluminum electrolytic capacitors, operators need to manually input various aging parameters, such as maximum current, test time, and temperature. This is not only time-consuming and labor-intensive but also prone to human error, affecting the accuracy and reliability of the test results. Furthermore, during aging testing, the impact of high current can easily cause overcurrent and other abnormalities in the capacitors and equipment. However, the overcurrent protection measures of traditional aging equipment are inadequate; when the current exceeds the safety threshold, it cannot cut off the power supply in time, often leading to damage to the equipment and capacitors, increasing production costs and repair time. Therefore, those skilled in the art have provided an aging device for bushing capacitor testing with automatic high-current setting to solve the problems mentioned in the background. Utility Model Content

[0003] The purpose of this invention is to provide an aging device for bushing capacitance testing with automatic high current setting, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An aging device for bushing capacitance testing with automatic high current setting includes a test frame. Multiple sets of evenly arranged charging units are arranged on the inner side wall of the test frame. A cooling fan is provided on the side wall of the test frame to dissipate heat from the charging units. Each charging unit consists of a power supply, a test circuit, a voltmeter, and an ammeter. The test circuit is equipped with an overcurrent protection module. The voltmeter and ammeter are used to monitor current and voltage parameters in real time. A three-color alarm light is fixedly connected to the upper surface of the test frame. A PLC controller and a touch screen human-machine interface are also fixedly connected to the side wall of the test frame. The touch screen human-machine interface is signal-connected to the PLC controller. The charging units and the three-color alarm light are electrically connected to the PLC controller.

[0006] Furthermore, the touch screen human-machine interface is used to input aging parameters for different types of aluminum electrolytic capacitors. The touch screen human-machine interface has a parameter preset function, which can store the aging parameter configurations for different types of aluminum electrolytic capacitors and supports one-click recall and parameter modification.

[0007] Furthermore, the PLC controller is used to receive and process aging parameters, including high current value, test time, and temperature.

[0008] Furthermore, the touchscreen human-machine interface is also equipped with a data acquisition card and a storage card. The data acquisition card is used to acquire the voltage, current, and temperature data of the capacitor in real time, and the storage card is used to store the acquired data and bind a timestamp.

[0009] Furthermore, the overcurrent protection module monitors the test circuit current in real time through a current sensor, and cuts off the power supply when the current exceeds a preset threshold.

[0010] Furthermore, the tri-color alarm light is electrically connected to the overcurrent protection module and is used to emit audible and visual alarm signals when the overcurrent protection is activated.

[0011] By adopting the above technical solution

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. It can store aging parameter configurations for different models of aluminum electrolytic capacitors, supporting one-click recall and parameter modification. This greatly improves the work efficiency of operators, eliminating the need to re-enter complex parameters for each test and reducing the possibility of human error. The voltmeter and ammeter monitor current and voltage parameters in real time, and the data acquisition card collects the capacitor's voltage, current, and temperature data in real time. The storage card stores the collected data and binds it with timestamps. This provides comprehensive and accurate data support for subsequent in-depth analysis and evaluation of the capacitor's aging performance, helping researchers to more accurately grasp the aging patterns and performance changes of the capacitor.

[0014] 2. The overcurrent protection module monitors the test circuit current in real time through a current sensor. When the current exceeds the preset threshold, it quickly cuts off the power supply. At the same time, the three-color alarm light emits an audible and visual alarm signal. This protection and alarm mechanism can effectively prevent abnormal damage to the equipment and capacitors under high current impact, ensuring the safe operation of the equipment and reducing test interruptions and economic losses caused by equipment failure.
