Abstract
The utility model discloses a high voltage switch cabinet for changing a rectangular busbar into a D-shaped busbar, comprising a high voltage switch cabinet and a busbar arranged inside the cabinet, wherein the busbar comprises a D-shaped conductive portion formed by an arc portion and a flat and straight portion, and a hollow portion formed by an arc portion and a flat and straight portion. The beneficial effects of the utility model are that the high voltage switch cabinet can prevent the corona phenomenon from generation and has excellent skin effect, through changing the shape of the cross section of the rectangular busbar into D shape.
Description
Technical field
The utility model relates to a kind of power distribution equipment, especially relates to a kind of high-tension switch cabinet that the rectangle busbar is improved to D type busbar.
Background technology
Bus is also claimed busbar or current-carrying row, is a kind of conductor of loaded current.In switchgear, be mainly used in and compile, distribute and transmit electric energy, connect primary equipment.According to the related data statistics, the short circuit accident overwhelming majority is directly or occurs in the bus position indirectly that busbar fault is a fault the most serious in the electrical equipment malfunction.Therefore, to bus select for use and application seems very crucial.
Traditional KYN28-12 high-tension switch cabinet bus-bar system is to adopt the rectangle busbar; Like Fig. 1, shown in Figure 2; Wherein Fig. 2 is the cutaway view of rectangle busbar 1 among Fig. 1; The cross sectional shape of rectangle busbar 1 has determined that it exists aspect kelvin effect and anticorona phenomenon not enough, because kelvin effect and the anticorona effect of rectangle busbar have its certain limitation, so just show its deficiency in switch cubicle current strength height, resistance is little, the electric field balanced intensity is high occasion.
The utility model content
The purpose of the utility model is exactly in order to address the above problem, and provides a kind of kelvin effect and anticorona effect a kind of preferably high-tension switch cabinet that the rectangle busbar is improved to D type busbar.
To achieve these goals, the utility model adopts following technical scheme:
A kind of high-tension switch cabinet that the rectangle busbar is improved to D type busbar; Comprise high-tension switch cabinet and be located at the inner busbar of cabinet; Said busbar cross sectional shape is D shape, and said D shape busbar comprises curved portions, flat part and gone along with sb. to guard him the hollow bulb that forms by curved portions and flat part.
The beneficial effect of the utility model is:
(1) it is good the rectangle busbar to be improved to D type busbar kelvin effect, in AC signal, when signal frequency increases, can strengthen the resistance of cores electric current; Thereby the electric current of cores is reduced; And exhausted most electronics, all will be moving along lead skin surface low, be kelvin effect.Through evidence: very few in the cores ELECTRON OF MOTION when the signal frequency height is above to 100MHz, like can the cores of lead being removed the sixth of the twelve Earthly Branches, and on conducting effect, the also unlikely remarkable influence that has.Know thus the rectangle busbar is improved to resistance, the increase ampacity that D type busbar can reduce conductor.
(2) it is effective the rectangle busbar to be improved to the anticorona phenomenon of D type busbar, and the phenomenon of electrified body surface partial discharge in gas or liquid medium is a corona phenomenon.Often occur in the very high zone of electric field strength in the non-uniform electric field (for example high-voltage conducting wires around, near electrified body most advanced and sophisticated).Its characteristics are: the photosphere similar with solar halo occur, send sound of ripping, tittering, frying, burning, etc sound, produce ozone, nitrogen oxide etc.Because D type busbar surface is circular, so than the anticorona phenomenon and the anti-short circuit better effects if of rectangle busbar.
Description of drawings
Fig. 1 is a rectangle busbar structural representation in the background technology.
Fig. 2 is an A-A cutaway view among Fig. 1.
Fig. 3 is the utility model cutaway view.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to set forth:
As shown in Figure 3; A kind of high-tension switch cabinet that the rectangle busbar is improved to D type busbar; Comprise high-tension switch cabinet and be located at the inner busbar of cabinet; Said busbar cross sectional shape is D shape, and said D shape busbar 2 comprises curved portions 22, flat part 23 and gone along with sb. to guard him the hollow bulb 21 that forms by curved portions and flat part.
It is good that the rectangle busbar is improved to D type busbar kelvin effect, in AC signal, when signal frequency increases, can strengthen the resistance of cores electric current; Thereby the electric current of cores is reduced; And exhausted most electronics, all will be moving along lead skin surface low, be kelvin effect.Through evidence: very few in the cores ELECTRON OF MOTION when the signal frequency height is above to 100MHz, like can the cores of lead being removed the sixth of the twelve Earthly Branches, and on conducting effect, the also unlikely remarkable influence that has.Know thus the rectangle busbar is improved to resistance, the increase ampacity that D type busbar can reduce conductor.
It is effective that the rectangle busbar is improved to the anticorona phenomenon of D type busbar, and the phenomenon of electrified body surface partial discharge in gas or liquid medium is a corona phenomenon.Often occur in the very high zone of electric field strength in the non-uniform electric field (for example high-voltage conducting wires around, near electrified body most advanced and sophisticated).Its characteristics are: the photosphere similar with solar halo occur, send sound of ripping, tittering, frying, burning, etc sound, produce ozone, nitrogen oxide etc.Because D type busbar 1 surface is circular, so than the anticorona phenomenon and the anti-short circuit better effects if of rectangle busbar.
The above is merely the preferred implementation of the utility model, and the protection range of the utility model is not limited in above-mentioned execution mode, and every technical scheme that belongs to the utility model principle all belongs to the protection range of the utility model.For a person skilled in the art, some improvement of under the prerequisite of the principle that does not break away from the utility model, carrying out, these improve the protection range that also should be regarded as the utility model.
