Abstract
The utility model discloses a direct-current support capacitor which comprises at least two capacitor module units arranged at intervals, a cooling pipe is arranged between the capacitor module units, and the cooling pipe includes a water inlet and a water outlet. According to the utility model, the defect that the temperature inside the capacitor rises too quickly can be avoided and the service life of the capacitor can be prolonged.
Description
Technical field
The utility model relates to the capacitor technology field.
Background technology
Capacitor in use causes the rising of temperature easily, and the rising of temperature causes the aging of the interior medium of capacitor, finally causes the inefficacy of capacitor.Traditional capacitor radiating effect is undesirable, so that the life-span of capacitor is shorter.
Summary of the invention
For the deficiencies in the prior art, a kind of direct current support capacitor is provided, can effectively prevent the in use easy problem that raises of temperature of capacitor.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of direct current support capacitor, comprise the capacitor module unit that at least two group intervals arrange, be provided with cooling water pipe between described capacitor module unit, described cooling water pipe comprises a water inlet and a delivery port.
In the technique scheme, preferred, described cooling water pipe includes U-shaped kink.
The utility model compared with prior art has following beneficial effect: by cooling water pipe is set, the heat that capacitor internal is produced of effective cooling has prevented the too fast problem of capacitor internal temperature rising, has prolonged the useful life of capacitor.
Description of drawings
Fig. 1 is the novel structural representation of this use.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail: referring to Fig. 1, a kind of direct current support capacitor, described direct current support capacitor comprises the capacitor module unit 3 that two groups of intervals arrange, be provided with cooling water pipe 1 between described capacitor module unit 3, described cooling water pipe 1 comprises a water inlet 10 and a delivery port 11.
Described cooling water pipe includes U-shaped kink 12, described U-shaped kink 12 covers the lateral wall of whole capacitor module unit 3, when the capacitor internal excess Temperature, pass into cooling fluid by water inlet 10 places at cooling water pipe 1, when cooling fluid was flowed through between two groups of capacitance module unit 3 of capacitor internal, then the heat between the Absorption Capacitance modular unit flowed out from delivery port 11, derive timely the heat of capacitor internal, prevented the situation generation that temperature raises too fast.
Claims (2)
