Abstract
The utility model relates to a bus structure for a solar photovoltaic header box, belonging to the technical field of solar photovoltaic power generation systems. The bus structure comprises a bus body, and is characterized in that a group of connection plugging teeth is separately extended from one side of the bus body along the length direction. The bus structure for the solar photovoltaic header box has the advantages that since the group of plugging teeth is separately extended from one side of the bus body along the length direction, the connection plugging teeth can be directly electrically connected with parts of electrical equipment such as a breaker, thereby reducing workload of wiring, and being able to substantially improve wiring efficiency; and since cables as conductive connection lines in the prior art are abandoned, the inside of the header box can be ensured to be clean, the total cost of the header box is reduced, and resources are saved.
Description
Technical field
The utility model belongs to the solar photovoltaic generation system technical field, is specifically related to a kind of photovoltaic header box bus structure.
Background technology
Can be by the Chinese patent Granted publication CN202183743U(photovoltaic combiner box to being not limited to exemplify about the concept of photovoltaic header box), CN201623478U(photovoltaic DC mildew-resistant header box), the CN202333456U(header box) and the CN202259364U(header box) etc. reading understood fully.
Usually need to install the miniature circuit breaker of many same sizes in header box, by circuit breaker by power supply output and with the supporting and photovoltaic generating system of complete of photovoltaic inversion depressor.Positive electrode bus in header box and negative pole bus are referred to as bus, and the some anodal parallel connection of solar photovoltaic battery component output accesses positive electrode bus, and some negative poles access the negative pole bus, and bus is connected with aforesaid circuit breaker electric.
Figure 1 shows that the schematic diagram that the photovoltaic header box in prior art is used bus structure and is connected with circuit breaker, as shown in Figure 1, comprise bus bulk 1, at the length direction interval of this bus bulk 1, distributions has one group of wiring position, and one group of conductive connecting of being filled the post of by cable 3 is being electrically connected to miniature circuit breaker 2 corresponding to place, described wiring position.
The bus bulk 1 of said structure implement with miniature circuit breaker 2 between electrical connection the time can expose following technical problem: the one, due to its (bus bulk 1) can't be directly and miniature circuit breaker 2 be electrically connected, thereby the transition of needs dependence conductive connecting 3, the wiring workload is increased and affect operating efficiency; The 2nd, due to the existence of conductive connecting 3, therefore cause in header box messy; The 3rd, because conductive connecting 3 is cable, so price is higher, thereby has increased the holistic cost of header box; The 4th, because being used cable, needs fill the post of conductive connecting 3, therefore be unfavorable for economizing on resources.
For above-mentioned prior art, be necessary to be improved, the applicant has done useful design for this reason, and technical scheme described below produces under this background.
Summary of the invention
Task of the present utility model be to provide a kind of without relying on conductive connecting can by bus bulk directly and implement electrical connection between miniature circuit breaker and use alleviate the wiring workload and improve wiring efficiency, avoid in header box producing messy, reduce the holistic cost of header box and the photovoltaic header box bus structure economized on resources.
Task of the present utility model completes like this, and a kind of photovoltaic header box bus structure, comprise a bus bulk, and characteristics are: be extended with one group of circuit breaker in a side of the length direction of described bus bulk with the interval state and connect gear shaping.
In a specific embodiment of the present utility model, at an end of described bus bulk, offer an electric-conductor connecting hole.
In another specific embodiment of the present utility model, what described circuit breaker connected gear shaping is shaped as rectangle or V font.
The technical scheme that the utility model provides is because a side of the length direction at bus bulk is extended with one group of circuit breaker connection gear shaping with the interval state, therefore circuit breaker can be connected to gear shaping directly directly is electrically connected with the parts such as circuit breaker as electric equipment, not only the wiring workload can be alleviated, and wiring efficiency can be significantly improved; Owing to having abandoned the conductive connecting of being filled the post of by cable in the prior art, therefore can ensure the interior clean and tidy effect of header box, reduce the holistic cost of header box and economize on resources.
The accompanying drawing explanation
Fig. 1 is bus and the application examples schematic diagram for the photovoltaic header box in prior art.
Fig. 2 is structure chart of the present utility model.
Fig. 3 is application examples schematic diagram of the present utility model.
Embodiment
Embodiment:
Refer to Fig. 2, provided a bus bulk 1, this bus bulk 1 is preferably used electric conducting material to make, but also can use insulating material as matrix and at matrix surface coated with conductive material, and an end of bus bulk 1 forms an electric-conductor connecting hole 12 for being connected with other conductive component.
The technical essential of the technical scheme provided as the utility model: be extended with interval state (equidistant intervals state) circuit breaker that one group of quantity is not subject to illustrating restricted number in a side of the length direction of bus bulk 1 and connect gear shaping 11, thereby make whole piece of bus bulk 1 show as the comb shape structure.
The geometry that aforesaid circuit breaker connects gear shaping 11 can also be V font or other similar shape of English alphabet except the rectangle shown in Fig. 2.
Application examples:
Refer to Fig. 3, one group of miniature circuit breaker 2 as electric component has been shown in this Fig. 3, in the time bus bulk 1 will being implemented to be connected with miniature circuit breaker 2, as long as circuit breaker is connected to gear shaping 11, insert the wiring position of (insertion) miniature circuit breaker 2 and limited by screw.As shown in Figure 3, adjacent circuit breaker connect the distance between gear shaping 11 be and two adjacent miniature circuit breakers 2 between distance adapt.
As shown in the above description, the technical scheme that the utility model provides has been confirmed the applicant all sidedly at the technique effect described in the technique effect hurdle.
