Since the heat dissipating pipelines are arranged at the middle positions between every two adjacent groups of capacitors, the heat between the two adjacent groups of capacitor banks can be dissipated quickly, the heat dissipation effect is ideal, and the service life of the capacitors are greatly prolonged.

Description

Pipeline type integral type capacitor

Technical field

The utility model relates to the capacitor that uses in a kind of electric power system, relates in particular to a kind of self-recovery low-voltage parallel capacitor.

Background technology

Self-recovery low-voltage parallel capacitor of the prior art generally comprises casing, be contained in insulating oil in casing, be immersed at least two group electric capacity in insulating oil 4, with every group of binding post that electric capacity is corresponding.The heat that produces between every group of capacitance group interacts soaring, and heat is difficult to discharge, and causes inside and outside temperature difference to reach more than 8 ℃, it is mainly by the box outer surface heat radiation, radiating effect is poor, and is very large to the capacitor cell infringement of capacitor, directly affects the useful life of capacitor.No. 01105202.3, Chinese invention patent application, open day on August 21st, 2002, a kind of air duct radiation type power capacitor is disclosed, comprise housing, be contained in the insulating oil in housing, be immersed in the capacitor cell in insulating oil, the plug of described capacitor cell parallels with capacitor height, described power capacitor is provided with and is being vertically some the air ducts that above-below direction passes the whole height of power capacitor, air duct is arranged on the both sides of capacitor cell, this structure capacitive device has solved the heat dissipation problem of capacitor preferably, but because the heat that produces between electric capacity interacts soaring, wherein between electric capacity, the temperature at middle part is the highest in fact, this application capacitor is arranged on air duct the both sides of capacitor cell, though can play certain thermolysis, but radiating effect is bad, and this application capacitor need to adopt more radiating tube, these radiating tubes need to housing phase welded seal, therefore adopt more radiating tube not only to process loaded down with trivial details, and complex structure, be unfavorable for cost control.

Summary of the invention

The purpose of this utility model is the defective that exists for prior art, and a kind of simple in structure, pipeline type integral type capacitor that radiating effect is desirable is provided.

for achieving the above object, the utility model adopts following technical proposals: a kind of pipeline type integral type capacitor, comprise casing, be placed at least two group capacitance group of casing, the binding post corresponding with each capacitance group, described each capacitance group is arranged in the matrix of multiple lines and multiple rows by several capacitor cells, be connected in parallel between capacitor cell in each capacitance group, the plug of each capacitor cell is parallel to each other and is perpendicular with the short transverse of casing, centre position between two adjacent groups electric capacity is provided with a hot channel, each hot channel runs through the whole height of casing, the two ends lateral wall of each hot channel respectively with the upper and lower covers fixed seal connection of casing.

As a kind of improvement: the cross section of described hot channel is rectangle.

As a kind of improvement: described capacitor comprises two groups of capacitance group, and the capacitor cell stack that every group of capacitance group is connected in parallel by nine capacitor cells is arranged in the matrix of three row three row, and the centre position between two groups of capacitance group is provided with a hot channel.

The beneficial effects of the utility model, in technique scheme, owing to just being provided with hot channel between two adjacent groups electric capacity, so structure is relatively simple, is conducive to processing and saves cost; Because hot channel is arranged on centre position between two adjacent groups electric capacity, thereby the heat between the two adjacent groups capacitance group is discharged fast, its radiating effect is more satisfactory, has greatly improved the useful life of capacitor.And every group of capacitance group of the utility model is arranged in the matrix of multiple lines and multiple rows by several capacitor cells, and with respect to the capacitor of single-row electric capacity, it can provide more electric weight, powers more lasting, and be stable.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Description of drawings

Fig. 1 is the structural representation of a kind of embodiment of the utility model pipeline type integral type capacitor.

Fig. 2 is the vertical view of Fig. 1.

Embodiment

As shown in Figure 1 and Figure 2, a kind of embodiment of the utility model pipeline type integral type capacitor, comprise casing 1, be placed at least two group capacitance group of casing 1, the binding post 3 corresponding with each capacitance group, described each capacitance group is arranged in the matrix of multiple lines and multiple rows by several capacitor cells 5.The capacitor of the present embodiment comprises two groups of capacitance group, and capacitor cell 5 stacks that every group of capacitance group is connected in parallel by nine capacitor cells 5 are arranged in the matrix of three row three row, and the centre position between two groups of capacitance group is provided with a hot channel 2.Be connected in parallel between capacitor cell 5 in each capacitance group, the plug 4 of each capacitor cell 5 is parallel to each other and is perpendicular with the short transverse of casing 1, centre position between two adjacent groups electric capacity is provided with a hot channel 2, each hot channel 2 runs through the whole height of casing 1, adopt scolding tin seam fixing seal between the two ends lateral wall of each hot channel 2 and the upper and lower covers of casing, realize the upper and lower covers fixed seal connection of hot channel 2 two ends lateral walls and casing 1.

The upper end of described hot channel 2 becomes upper venthole, the lower end of hot channel 2 becomes lower air admission hole, cold air in service is from the bottom inflow gas inlet hole of casing 1, and the heat that produces between the two adjacent groups capacitance group is discharged from casing 1 top venthole, thereby reaches great heat radiation effect.And every group of capacitance group of the present utility model arranged by the matrix of 5 one-tenth multiple lines and multiple rows of a plurality of capacitor cells, compare with other capacitors with volume, the utility model is in the situation that guarantee great heat radiation effect, the arrangement of the capacitor cell in capacitor is more reasonable, the capacitor cell quantity of holding is also more, more electric weight can be provided, power more lasting, stable.

in order to increase area of dissipation, the cross section of described hot channel can be rectangle, the long limit of rectangle hot channel 2 parallels layout with the minor face of rectangular box (being the left and right sidewall of casing 1), the minor face of rectangle hot channel 2 is positioned as close to the long limit (being the front and back sidewall of casing 1) of rectangular box 1, in order to reduce the casing overall volume, spacing between the two adjacent groups capacitance group can be as much as possible little, therefore compare for circular or foursquare hot channel with cross section, under uniform distances condition between the two adjacent groups capacitance group, rectangle hot channel area of dissipation is larger, under the constant condition of area of dissipation, can also reduce by two groups of spacings between electric capacity, thereby dwindle the casing overall volume.Certainly the cross section of hot channel 2 can also be other flat patterns, arranges as long as the minor face of flat pattern hot channel is positioned as close to the front and back sidewall of casing 1, can reach the purpose of this utility model.

Above-described embodiment is described in detail the utility model, is not obviously to restriction of the present utility model, and the utility model can also have many variations, and therefore protection of the present utility model orientation should be determined by claim.
