Abstract
The utility model relates to a novel inverter direct current bar. The novel inverter direct current bar comprises a direct current busbar and vertical connecting pieces. The vertical connecting pieces of the novel inverter direct current bar of the utility can be effectively combined with copper wiring terminals of a direct current cable, and fix the direct current cable on the direct current bar fast and steadily, and are tightly fixed by bolts. With the novel inverter direct current bar of the utility model adopted, accurate and firm butt-joint installation of the direct current bar and the direct current cable can be realized smoothly, and reworking of copper wiring terminal connection can be reduced, and construction efficiency can be improved.
Description
Technical field
The utility model relates to a kind of inverter direct current row, comprises busbar and vertical connector, described DC master row body, and both sides are provided with screw, use for busbar is fixing.Described vertical connector is installed simply the time and labour saving for connecting the connector of direct current cables copper lug; And install visually, can save construction cost.
Background technology
The photovoltaic DC-to-AC converter DC side that photovoltaic power plant uses adopts copper bar to connect mostly, because of galvanic characteristic, requires the copper lug junction, must be fastening closely knit.Now general connected mode connects copper bar and direct current cables copper lug for using bolt, perforate direction because of copper bar, can only see nut end during construction, brought certain degree of difficulty and connected the very difficult situation about connecting between copper lug and the copper bar of observing intuitively in back to construction, can't judge the effect of connection, finally influence project progress.
In the construction, inverter direct current row and direct current cables generally adopt bolt to connect processing mode at present: existing mounting means, determine direct current cable footpath according to the capacity of inverter earlier, and select the copper lug of relevant specification to carry out the crimping pyrocondensation; After carrying out the direct current cable, connect copper lug and direct current row.Connecting fastening degree naked eyes can't effectively detect, and in view of this, necessaryly provides a kind of and connects firm and visual inverter direct current row is installed.
Summary of the invention
The purpose of this utility model is: provide a kind of connection firmly and direct current row easily is installed, adjust the problem of inconvenience and fastness deficiency with bolt position between solution copper bar and the direct current cable.
To achieve these goals, the utility model provides a kind of novel inverter direct current row.
A kind of novel inverter direct current row, it comprises DC master row and vertical connector.
Described DC master row both sides arrange screw, and each described vertical connector has a connecting hole.
Compared with prior art, vertical connector of the present utility model can be effectively and the effective combination of the copper lug of direct current cable, and the firm direct current cable being connected on the direct current row fast is through bolted.Therefore direct current row of the present utility model can realize smoothly with the direct current cable between accurately, firmly dock installation, and reduced the phenomenon that the copper lug connection is done over again, improved efficiency of construction.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model inverter direct current row and useful technique effect thereof are elaborated.
Fig. 1 is the utility model direct current row's organigram.
Fig. 2 uses view for the utility model direct current row.
Embodiment
See also shown in Figure 1ly, the utility model assembly comprises DC master row 7 and vertical connector 1.
The direct current cable wrap is drawn together copper lug 5 and cable 6.
Direct current cable copper lug 5 after installing is through by bolt 2 in direct current row's the screw of vertical connector 1, uses bolt 2 to be fastenedly connected by vertical connector 1 screw and nut 4.
The method of using the utility model direct current row to construct may further comprise the steps:
(1) cable 6 and copper lug crimping construction (step Step1): use copper lug to be enclosed within the cable end place and use hydraulic tongs to carry out crimping, finish the making work of direct current cable;
(2) screw rod 3 positions of adjustment bolt 2 make it and vertical connector 1 and copper lug 5 screw contrapositions (Step2);
(3) according to direct current row and direct current cable screw contraposition installation requirement, be fastenedly connected (step Step3);
(4) finishing direct current row installs with the contraposition of direct current cable.
In conjunction with top description as can be known, connected mode between the utility model inverter direct current row and the direct current cable can effectively reduce the installation difficulty of direct current row and direct current cable, reduces the phenomenon of doing over again of direct current cable installation, and simple operation, installation personnel can directly observe condition of construction.Shorten installation period thereby be conducive to increase work efficiency, therefore can be to reducing the construction cost of photovoltaic power plant, the economy that improves nuclear power plant plays positive role.
The elaboration of book and explanation according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned execution mode.Therefore, the embodiment that discloses and describe above the utility model is not limited to also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not constitute any restriction to the utility model just for convenience of description.
Claims (2)
1. a novel inverter direct current row is characterized in that it comprises DC master row and vertical connector.
2. a kind of novel inverter direct current row according to claim 1 is characterized in that described DC master row both sides arrange screw, and each described vertical connector has a connecting hole.
