Problems solved by technology
[0002] At present, the ways to convert between the parallel mode and the series mode of the circuit include circuit breaker or relay linkage, isolating switch switching, changing the position of the connecting busbar, etc., each of which has its own disadvantages: circuit breaker or relay linkage can only be used for medium and small current circuit, and the cost is high and the space size is large; the isolation switch switch can be used in various occasions, but the structure is complex, the cost is high, and it is easy to misuse; changing the position of the connecting busbar is suitable for circuits with large current and infrequent switching. but easy to misuse

Embodiment
[0018] In the present invention, in order to avoid that there are two connection modes that are difficult to distinguish when the serial-parallel convertible busbar is switched from the parallel mode to the series mode, by changing the mutual positioning relationship of the installation dimensions of the connecting busbars, the When the parallel-converted busbar is converted from the parallel mode to the series mode, two different series modes can be clearly distinguished by the different installation methods of the connecting busbars.
[0019] As shown in FIG. 1 , the serial-parallel convertible busbars include line busbar 1-, line busbar 2-, line busbar 1+, line busbar 2+, connecting busbar BLP and connecting busbar CBLP, The connecting busbar BLP and the connecting busbar CBLP are Z-shaped, wherein the distance between the line busbar 1+ and the line busbar 2- is A; the line busbar 1- and the line busbar 2 The distance between + is B; the thickness of the connecting busbar ...

The invention relates to a busbar with capability of series-parallel conversion. The busbar comprises a circuit busbar 1-, a circuit busbar 2-, a circuit busbar 1+, a circuit busbar 2+, a connecting busbar BLP and a connecting busbar CBLP, wherein the connecting busbar BLP and the connecting busbar CBLP form a Z shape, and the distance between the circuit busbar 1+ and the circuit busbar 2- is A; the distance between the circuit busbar 1- and the circuit busbar 2+ is B; the thickness of the connecting busbar BLP and the connecting busbar CBLP is C; the distance between two contact surfaces of the connecting busbar BLP is A; the distance between two contact surfaces of the connecting busbar CBLP also is A; and B is equal to the sum of A and C. Therefore, when the busbar is switched from a parallel mode to a series mode, two different series modes can be obviously distinguished through different mounting modes of the connecting busbars, so that misoperation is avoided, potential safety hazards are eliminated, and the reliability is improved.
Description
technical field [0001] The invention relates to the field of power distribution devices, and relates to a busbar in a power supply system, specifically a busbar capable of serial and parallel conversion. Background technique [0002] At present, the ways to convert between the parallel mode and the series mode of the circuit include circuit breaker or relay linkage, isolating switch switching, changing the position of the connecting busbar, etc., each of which has its own disadvantages: circuit breaker or relay linkage can only be used for medium and small current circuit, and the cost is high and the space size is large; the isolation switch switch can be used in various occasions, but the structure is complex, the cost is high, and it is easy to misuse; changing the position of the connecting busbar is suitable for circuits with large current and infrequent switching. But it is easy to misuse. Among them, the bus bar refers to the copper bar or aluminum bar connecting the...
