Description
Technical Field
The utility model relates to a female technical field that arranges especially relates to a female row of stromatolite that is used for a plurality of power unit to connect.
Background
With the continuous progress of the frequency converter technology, most frequency converter products are advanced toward integration, miniaturization and high power. The female structure of arranging is all connect out separately from the positive negative pole end of rectification respectively to current power unit wiring, the required space of the whole copper bar overall arrangement of such structure is great, the stray inductance that this structure produced in the operation of converter is big again simultaneously, be unfavorable for integrating and the miniaturization of product, also do not favorable to power unit's maintenance and the reliable work of converter, the copper bar is as the adapting unit of a wiring, if can not guarantee the reasonable structure of arranging between positive copper bar and the negative pole copper bar, then cause converter circuit fault easily, still cause the wiring installation degree of difficulty easily, maintain the difficulty, be not suitable for a plurality of power unit's connection. How to guarantee the positive and negative poles of a plurality of power units are effectively and reliably and safely connected with the busbar and reduce the volume of the compressed copper bar to the maximum extent is the key of the integration and miniaturization of the copper bar.
Disclosure of Invention
To the problem that exists among the above-mentioned prior art, the utility model provides a female row of stromatolite for a plurality of power unit connection, under the power unit's of installation same number the condition, the female space that occupies that arranges of this stromatolite is little, simple to operate, and it is simple to maintain, practices thrift the copper bar simultaneously and reduces the cost, has reduced the production of converter stray inductance in the operation process again simultaneously.
The utility model adopts the technical scheme as follows: the utility model provides a female arranging of stromatolite for a plurality of power unit connect, is including arranging the negative plate on upper strata in, arranging medial insulating PC board in, arranging the positive plate of lower floor in, the width of negative plate is less than insulating PC board, and it has multiunit electrical connection point to distribute on the negative plate, and one side of negative plate is equipped with negative pole input port, on the positive plate, be equipped with the corresponding position department of negative plate electrical connection point and keep away the hole, the positive plate extends insulating PC board to be equipped with the electrical connection point corresponding with the negative plate electrical connection point on extending insulating PC board part, one side of positive plate is equipped with positive input.
Furthermore, the electric connection point department is equipped with the pressure riveting nut on positive plate, the negative pole copper bar passes through the combination cover bolt and presses the riveting nut to screw up and be connected.
Furthermore, a plurality of insulating PC plates are distributed above the part of the positive plate extending out of the insulating PC plate at intervals.
Furthermore, a plurality of insulating columns for fixing are fixed on the laminated busbar.
The utility model discloses a female row of stromatolite can connect a plurality of power unit, compares with prior art, and under the power unit's of the same number the condition of installation, the female space that occupies of arranging of this stromatolite is little, simple to operate, and it is simple to maintain, practices thrift the copper bar simultaneously, and the cost is reduced has reduced the production of converter stray inductance in the operation process again simultaneously.
