Abstract
The utility model relates to a novel signal acquisition unit. The signal acquisition unit includes an aluminum alloy box (1), a printed circuit board (2), signal acquisition and protection elements (3), an input wiring terminal (4), an earthing terminal (5), and a signal acquisition interface (6). The signal acquisition and protection elements (3) are integrated on the printed circuit board (2) and are fixed by means of welding. The printed circuit board (2) and the signal acquisition and protection elements (3) are fixed to the inside of the aluminum alloy box (1). The input wiring terminal (4) and the signal acquisition and protection elements (3) are connected to realize communication. The aluminum alloy box (1) is connected with the earthing terminal (5). The signal acquisition and protection elements are provided with the signal acquisition interface (6) which is connected with a measuring unit. According to the signal acquisition unit, a conventional iron casing oil-immersed structure is changed to an aluminum alloy housing dry structure, and thus the profile dimension and weight of the signal acquisition unit are effectively reduced, the portability is substantially improved, and the signal acquisition unit provides convenience for on-site detection and maintenance and the diversity of measurement interfaces.
Description
Technical field
The utility model relates to a kind of novel signal collecting unit, is particularly useful for the collection to its voltage and parameter signal thereof in high-voltage testing equipment operational process.
Background technology
At present; the most iron-clad oil immersed type structures that adopt of domestic signal gathering unit of the same type; guarantee its inner member electric property, cause it in the oversize site test that is not easy to of profile, to carry, also because its inside lacks, protect the oil immersed type structure of loop and employing that its maintenance difficulty is strengthened.
Utility model content
The utility model is for above-mentioned defect, and object is to provide a kind of can form good protection to internal electric, and can guarantee a kind of signal gathering unit of measuring accuracy.
The technical solution adopted in the utility model is for this reason: comprise aluminium alloy box (1), printed circuit board (2), signals collecting and protecting component (3), input wires terminal (4), ground terminal (5), signals collecting interface (6), signals collecting and protecting component (3) are integrated in printed circuit board (2) and go up and be welded and fixed, printed circuit board (2), signals collecting and protecting component (3) are fixed in aluminium alloy box (1), input wires terminal (4) and signals collecting and protecting component (3) are connected to form communicates by letter, on aluminium alloy box (1), establish ground terminal (5), signals collecting and protecting component (3) are provided with the signals collecting interface (6) being connected with measuring unit.
The utility model provides a kind of novel signal gathering unit, change original iron-clad oil immersed type structure into aluminum alloy casing dry construction, the utility model has adopted dry construction effectively to dwindle physical dimension and weight, portable performance is greatly improved, because needn't consider sealing property, for Site Detection maintenance and measurement interface diversity are provided convenience.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is front view of the present utility model.
In figure, 1 is that aluminium alloy box, 2 is that printed circuit board, 3 is that signals collecting and protecting component, 4 are that input wires terminal, 5 is that ground terminal, 6 is signals collecting interface.
Embodiment
