Embodiment 1

[0033] Basic as attached figure 1 Shown: Thermal equipment for capacitors, including:

[0034] The casing 10 is provided with a mounting hole, a bearing is arranged in the mounting hole, and a sponge water-absorbing layer is arranged on the bearing. Such a design can avoid icing in the bearing, and can also reduce the friction between the mounting hole and the support rod 11 .

[0035] Heat preservation cover 20, heat preservation cover 20 is fixedly installed in the housing 10, an installation cavity is formed between the heat preservation cover 20 and the housing 10, the outer surface of the heat preservation cover 20 is provided with a friction bottom layer, and the interior of the heat preservation cover 20 is provided with a sponge layer. Specifically, the material of the friction bottom layer may be a metal bottom layer, and textures that increase surface roughness are provided on the bottom layer.

[0036] Support rod 11, support rod 11 is positioned at installation c...

Embodiment 2

[0044] Compared with Example 1, the only difference is that a heat conduction hole is provided on the heat preservation cover, and a baffle is provided on one side of the heat conduction hole. The baffle is slidably connected with the heat preservation cover, and the baffle can cover the heat conduction hole. On the other side, there is a thermally conductive rod that expands with heat and contracts with cold, and the support rod is provided with a drain sheet for driving air flow.

[0045] Specific use: when the temperature in the installation cavity is low, the heat conduction rod is in a shrinking state, and the baffle blocks the heat conduction hole. After the temperature in the installation cavity rises, the heat conduction rod expands, the baffle is pushed away by the heat conduction rod, and the heat conduction hole is exposed Come. At this time, the temperature of the air in the installation cavity is also relatively high. After the heat conduction hole is opened, the ...

Embodiment 3

[0047] Compared with Embodiment 1, the only difference is that a magnet capable of forming a closed magnetic field is embedded in the shell, an induction coil is fixed on the support rod, a commutator is provided at the mounting hole, and the commutator is provided with respectively The first brush and the second brush are slidingly connected to the commutator, the first brush is electrically connected to the induction coil, the eddy current coil is embedded in the heat preservation cover, and the eddy current coil is electrically connected to the second brush.

[0048] Specific use: when the support rod rotates, an alternating current will be generated in the induction coil, and then pass through the first brush, the commutator, and the second brush to the eddy current coil, and the eddy current coil is embedded in the heat preservation cover. When there is an alternating current in the eddy current coil, the current in the eddy current coil can be used to heat the heat preser...

Abstract

The invention relates to the field of a capacitor. Aiming at the technical problem that an existing capacity cannot be used in an extremely cold temperature, warming equipment of a capacitor is provided. The warming equipment comprises a shell, a heat preservation cover, a support rod and a handle, wherein an installation hole is formed in the shell, the heat preservation cover is fixedly arrangedin the shell, an installation cavity is formed between the heat preservation cover and the shell, a friction bottom layer is arranged on an outer surface of the heat preservation cover, the support rod is arranged in the installation cavity, the support rod has a shape matched with the shape of the outer surface of the heat preservation cover, the support rod is rotatably arranged in the installation hole, the support rod rotates around the heat preservation cover in the installation cavity by taking the installation hole as a circle center, a fixed rod made of a thermal expansion and cold shrinkage material is arranged on the support rod, one end of the fixed rod is fixedly connected with the support rod, a friction body is fixedly arranged at the other end of the fixed rod and generatesfriction with the friction bottom layer to generate heat, and the handle is arranged outside the shell and is used for driving the support rod to rotate.

Description

technical field [0001] The invention relates to the field of capacitors, in particular to a warming device for capacitors. Background technique [0002] With the lack of resources and the impact of climate change, more and more attention has been paid to the exploration and development of the South Pole and the natural world. The temperature of the South Pole and the North Pole is extremely cold The measured average temperature is -58.4°C), how aluminum electrolytic capacitors can meet the ultra-low temperature extreme cold environment, and how to solve the ultra-low temperature resistance of aluminum electrolytic capacitors will be an indispensable measure. Aluminum electrolytic capacitors are usually used in the temperature range of -25°C to +70°C, and can also be used in the range of -55°C to +105°C. When the temperature is lower than -55°C, its capacity, loss, and leakage current will decrease. Deterioration occurs, affecting the use of capacitors and even losing their ...
