DETAILED DESCRIPTION

[0028] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example 1

[0030] like Figure 1 to Figure 5 As shown, an elliptical explosion-proof capacitor with a temperature control function comprises a container shell 1, a container cover 2 and a temperature control component 23. Two symmetrical positioning blocks 3 are slidably mounted inside the container shell 1. An explosion-proof device 4 is installed on one side of the positioning block 3. Two symmetrically arranged active sliders 5 and two symmetrically arranged driven sliders 6 are slidably mounted inside the container shell 1. A pressure rod 11 is welded on one side of the active slider 5, and a connecting rod 12 is welded on one side of the driven slider 6. The connecting rod 12 is slidably mounted inside the active slider 5. By setting the structures such as the block 5 and the driven slider 6, pressing the pressure rod 11, the active slider 5 moves inward and the connecting rod 12 slides inside it, so that the driven slider 6 is driven downward to move during the sliding of the connecting rod 12, so that the driven slider 6 is separated from the positioning block 3, and the explosion-proof device 4 is removed. When installing, the positioning block 3 is reinserted, and the pressure rod 11 is released. Under the action of the first spring 9 and the second spring 10, the driven slider 6 re-enters the positioning block 3 to fix the explosion-proof device 4, simplifying the assembly and disassembly process, reducing the difficulty of operation, and improving convenience.

[0031] like Figure 4-5 As shown, two symmetrically arranged active slide grooves 7 are provided inside the container shell 1, the active slider 5 is slidably connected inside the active slide groove 7, and a first spring 9 is commonly connected between one side of the active slider 5 and the side wall of the active slide groove 7.

[0032] like Figure 4-5 As shown, two symmetrically arranged driven grooves 8 are opened inside the container shell 1, and the driven slider 6 is slidably connected inside the driven groove 8. A second spring 10 is commonly connected between the bottom of the driven slider 6 and the bottom wall of the driven groove 8.

[0033] like Figure 4-5 As shown, an inclined groove 13 is provided inside the driven slider 6 , and one end of the connecting rod 12 is slidably connected inside the inclined groove 13 .

[0034] like Figure 4-5 As shown, a positioning groove 15 is provided inside the positioning block 3, and the driven slider 6 and the positioning groove 15 have the same shape and size.

[0035] like Figure 4-5 As shown, a moving groove 14 is provided inside the container shell 1 , and the connecting rod 12 is slidably connected inside the moving groove 14 .

[0036] In this embodiment, when the explosion-proof device 4 is assembled and disassembled, the two pressure rods 11 are pressed to drive the active slider 5 to move in the same direction, and the connecting rod 12 slides in the inclined groove 13. During this process, the connecting rod 12 drives the driven slider 6 to slide downward. After the driven slider 6 completely leaves the positioning inside the positioning block 3 and enters the driven slide groove 8, the explosion-proof device 4 can be removed. When reinstalling, the pressure rod 11 is pressed, and after inserting the positioning block 3, the pressure rod 11 is released. The active slider 5 and the driven slider 6 are reset under the action of the first spring 9 and the second spring 10, and the installation of the explosion-proof device 4 is completed. It should be noted that the explosion-proof device 4 is a prior art and will not be described in detail here.

[0037] Example 2

[0038] like Figure 1 to Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the temperature control component 23 includes a mounting seat 16, the mounting seat 16 is arranged at the bottom of the container cover 2, and the top of the container cover 2 is respectively provided with a fixing block 17 and a fixing plate 18, the bottom of the fixing block 17 is fixedly connected to a first mounting plate 19 by screws, and the bottom of the fixing plate 18 is fixedly connected to a plurality of second mounting plates 20 by bolts, a temperature control device 21 is welded on the first mounting plate 19, and a plurality of second mounting plates 20 are commonly welded inside with temperature control terminals 22, and a plurality of heat sinks 24 are installed inside the container shell 1. Through the arrangement of the temperature control device 21 and the temperature control terminal 22 and other structures, the temperature control terminal 22 transmits instructions to the temperature control device 21 so that it can monitor the temperature of the capacitor in real time, and automatically adjust according to the set temperature range, accurately control the working temperature of the capacitor, and prevent overheating or overcooling.

[0039] like Figure 2-3 As shown, a plurality of mounting grooves are provided inside the mounting seat 16, and the first mounting plate 19 and the second mounting plate 20 are both mounted inside the mounting grooves.

[0040] In this embodiment, when the temperature inside the capacitor exceeds the set threshold, the temperature control device 21 will start. The temperature control device 21 is usually composed of a temperature sensor such as a thermistor or a thermistor and a control circuit. When the temperature sensor detects that the temperature inside the capacitor exceeds the set value, the control circuit will trigger a protection mechanism, such as cutting off the power supply or reducing the current to prevent the capacitor from being damaged by overheating. The temperature control terminal 22 is an additional device on the capacitor, which is used to connect the temperature sensor and the control circuit. When the temperature sensor detects that the temperature inside the capacitor exceeds the set value, the control circuit will trigger a protection mechanism. The temperature control terminal 22 is connected to the control circuit through a wire to transmit signals and control instructions. It should be noted that by adding a hole on the container cover 2, installing the temperature control terminal 22, changing the position of the temperature control terminal 22, and changing the material and thickness relationship between the container cover 2 and the container shell, the capacitor element is damaged and releases gas. If the temperature control terminal 22 is added, the mechanical properties of the cover are changed, making it inconvenient to open the explosion-proof device 4 in the cover.

[0041] Furthermore, the heat sink 24 in the container shell can dissipate heat, which can effectively reduce the temperature inside the capacitor and prevent overheating from affecting the performance and service life of the electrical components.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
