Description

Technical Field

[0001] The present invention relates to the field of electrical appliance detection, in particular to the detection technology of electrical appliance components, and more specifically to an electrolytic capacitor temperature measuring device. Background Art

[0002] Electrolytic capacitors are a type of capacitor, mainly composed of metal foil (such as aluminum) and electrolyte (liquid), and their original work is to convert electric field energy into capacitive energy. Since the two electrodes of the electrolytic capacitor are immersed in the electrolyte, when the voltage is applied to the capacitor, the ions in the electrolyte will move and generate an electric field between the electrodes. Therefore, the capacitance of the electrolytic capacitor is affected by the ambient temperature, so it is of great significance to accurately measure the ambient temperature of the electrolytic capacitor.

[0003] In order to accurately measure the ambient temperature of electrolytic capacitors, in addition to selecting appropriate sensors, thermometers and other measuring tools, it is also very important to stably place these measuring tools within the effective range of electrolytic capacitor temperature measurement.

[0004] However, it is very regrettable that there is almost no research in the existing technology on how to stably place the measuring tool within the effective temperature measurement range, and no related technology has been reported. Summary of the invention

[0005] The technical problem to be solved by the present invention is how to stably fix measuring tools such as thermocouples within a suitable temperature measurement range.

[0006] In order to solve the above technical problems, the present invention discloses an electrolytic capacitor temperature measuring device, including a support frame and a temperature measuring fixture; the temperature measuring fixture includes a temperature measuring base, a temperature measuring tool chuck, and a temperature measuring support rod, the temperature measuring support rod is fixed on the temperature measuring base, and the temperature measuring tool chuck is fixed on the top of the temperature measuring support rod; the temperature measuring base is a hollow tube with an opening; the support frame includes a plurality of retractable rings and a horizontal support rod fixed in the top retractable ring along the diameter direction.

[0007] When measuring, first put multiple retractable rings on the outside of the electrolytic capacitor and tighten them, and the horizontal support rod in the top retractable ring is close to the top of the electrolytic capacitor; then the temperature measuring fixture is inserted into the multiple measuring positions of the support frame through the opening on the temperature measuring base, and finally, the thermocouple and other measuring sensors are clamped in the chuck of the temperature measuring tool. Since the temperature measuring fixture can be fixed at different positions of the retractable ring and the horizontal rod as needed, and can be moved at different positions, it can be selected and moved to any point horizontally.

[0008] The present invention also discloses a preferred technical solution, namely, a longitudinal support rod is further provided, on which a movable buckle which can move up and down is fixed, and the movable buckle is mainly composed of a hollow tube and a buckle arranged on the outside of the hollow tube; the inner side of the hollow tube matches the longitudinal support rod, one end of the buckle is fixed to the outer wall of the hollow tube, and the other end is not fixed to the hollow tube, thereby forming an open end that can be snapped in.

[0009] When the movable buckle moves up and down along the longitudinal support rod, the height of the retractable ring fixed by it also changes accordingly, and then the height of the temperature measuring fixture can be changed, thereby realizing the movement of any point in the vertical direction.

[0010] Further preferably, a protrusion is further provided on the inner side wall of the temperature measuring base, and the protrusion can form an interference fit with the support frame after the temperature measuring fixture is fixed to the support frame, thereby improving the stability of the overall structure.

[0011] Similarly, a protrusion is arranged on the inner side wall of the movable buckle, and the protrusion can also achieve a further stable fixing effect by interference fit when the movable buckle is fixed to the longitudinal support rod.

[0012] As a preferred technical solution, the horizontal support rods include two rods that are vertically arranged to each other.

[0013] The present invention provides a variable multi-point measurement stable support for the temperature measuring fixture through a support frame structure, thereby improving the convenience and stability of electrolytic capacitor temperature measurement and enhancing measurement accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 This is a schematic diagram of the electrolytic capacitor temperature measurement device.

[0015] Figure 2 This is an enlarged diagram of the movable buckle.

[0016] Figure 3 This is an enlarged schematic diagram of the temperature measuring fixture. DETAILED DESCRIPTION

[0017] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples. Example

[0018] like Figures 1 to 3 As shown, the electrolytic capacitor temperature measuring device disclosed in this embodiment includes a support frame 1 and a temperature measuring fixture 2; further combined with Figure 1 and Figure 3It can be seen that the temperature measuring fixture includes a temperature measuring base 201, a temperature measuring tool chuck 202, and a temperature measuring support rod 203. The temperature measuring support rod 203 is fixed on the temperature measuring base 201, and the temperature measuring tool chuck 202 is fixed on the top of the temperature measuring support rod 203; the temperature measuring base is a hollow tube with an opening, such as Figure 3 As shown in , it can be seen that there is an opening at the bottom, and the hollow tubes on both sides of the opening are close together. When force is applied, the opening opens, and when the force is removed, the hollow tubes on both sides close, which does not affect its rigidity and stability; then we go back to Figure 1 From the perspective of FIG. 1 , the support frame includes a plurality of retractable rings. Figure 1 The first telescopic ring 101 and the second telescopic ring 102 and the horizontal support rod 104 fixed in the top telescopic ring 103 along the diameter direction are shown in FIG. Figure 1 It can be seen that in this embodiment, the two horizontal support rods 104 are perpendicular to each other.

[0019] Further, in this embodiment, combined with Figure 1 We can see that a longitudinal support rod 105 is also provided, combined with Figure 1 and Figure 2 It can be seen that a movable buckle 3 that can move up and down is fixed on the longitudinal support rod, and the movable buckle 3 is mainly composed of a hollow tube 301 and a buckle 302 arranged on the outside of the hollow tube; the inner side of the hollow tube matches the longitudinal support rod, one end of the buckle is fixed to the outer wall of the hollow tube, and the other end is not fixed to the hollow tube, thereby forming an open end that can be snapped in.

[0020] In order to enhance the stability after fixation, protrusions can be provided on the inner side walls of the movable buckle 3 and the temperature measuring base 201. These protrusions can form an interference fit due to being squeezed, thereby improving the stability of the movable buckle and the temperature measuring base. Figure 3 The protrusion 4 in the middle can be seen to be protruding inward to form a triangular edge, so it will tightly press against the retractable ring on the support frame, making the fixation more stable.

[0021] Next, based on the above disclosed structure, we further explain the workflow and technical effects of the present invention.

[0022] When the temperature of the electrolytic capacitor needs to be measured, first, the longitudinal support rod 105 is fixed to the outer surface of the electrolytic capacitor with glue or other viscous media, the position of the movable buckle 3 is adjusted to a suitable height, and the first retractable ring 101 and the second retractable ring 102 are respectively inserted into the buckles 302 of different heights through the buckle 302 of the movable buckle, so as to achieve the fixation of the retractable ring. The interface of the retractable ring is in the form of a cable tie, which is tightened to fit tightly against the outer wall of the electrolytic capacitor. The support frame structure formed at this time is as shown in FIG. Figure 1As shown in FIG. 1 , the top is a top telescopic ring 103 with a horizontal support rod 104 , the bottom is a second telescopic ring 102 and a first telescopic ring 101 in sequence, and the side is a longitudinal support rod 105 .

[0023] Then, the temperature measuring clamp 2 is installed at a specific detection position as needed, and is fixed to the horizontal support rod 104, the longitudinal support rod 105, or the top retractable ring 103, the second retractable ring 102, and the first retractable ring 101 through the opening on the temperature measuring base 201 of the temperature measuring clamp.

[0024] After fixing the temperature measuring fixture 2, place the thermocouple and other detection tools in the temperature measuring tool chuck 202 of the temperature measuring fixture 2. Since the distance between the temperature measuring tool chuck and the electrolytic capacitor is basically the height of the temperature measuring support rod 203, according to the detection needs, we set the height of the temperature measuring support rod 203 to about 2 cm, thereby ensuring that the distance between the thermocouple and the electrolytic capacitor to be detected is 2 cm.

[0025] Finally, turn on the thermocouple sensor, record the temperature changes, and complete the temperature measurement.
