Description
Technical field
The utility model relates to a kind of dry-type transformer grounding device, relates to electrical safety engineering.
Background technology
According to electric power safety working regulation regulation, for may installing earth connection or the grounding switch that closes (device) by power transmission to the everyway of power failure equipments.Carry out closing by running the isolated operation mesohigh side grounding switch turning maintenance at transformer, low-pressure side installs one group of three-phase ground line.And if high-pressure side cable is long, for preventing residual charge, often one group of earth connection also can be installed in high-pressure side.
Due to the difference of transformer installation site each in actual conditions, when causing some transformers to overhaul, the conductor end of three-phase ground line installs comparatively difficulty on earth terminal, has had a strong impact on operating efficiency.Also have take the earth terminal of three-phase ground line to be connected in transformer case ground connection copper cash on way, but this kind of installation method one shows slightly lack of standardization, two is that the earth terminal of three-phase ground line cannot compress.
Summary of the invention
The purpose of this utility model is to provide a kind of dry-type transformer grounding device, and access node structure is not simple for this kind of earthing device, and convenient for three-phase ground line rapid grounding.
The technical solution of the utility model is: a kind of dry-type transformer grounding device, comprise the frid be connected with the bottom plate of machine cabinet of dry-type transformer, the side plate of described frid is connected with the binding post for being connected with the ground connection copper cash of dry-type transformer rack through the first cross bolts, frid opposite side is connected with and turns shape copper coin, describedly turn sandwiched on shape copper coin and be equipped with a removable earth clip for being connected with three-phase ground line, the bracing frame of described removable earth clip is Contraband type, the upside transverse slat of support frame as described above longitudinally runs through the screw rod having one and its bolt, described screw rod lower end is hinged with one and matches to clamp with the downside transverse slat of bracing frame the clamping plate turning shape copper coin.
Further, described frid is buckled on the bottom plate of machine cabinet of dry-type transformer, and is connected with bottom plate of machine cabinet through longitudinal clamping screw.
Further, described screw rod upper end is laterally equipped with the cross bar for rotary screw, and described cross bar two ends are respectively arranged with rubber layer.
Further, the upper surface of the downside transverse slat of support frame as described above is provided with the anti-skidding flank of tooth, and the downside of described clamping plate arranges the anti-skidding flank of tooth.
Further, the sidepiece of described support is equipped with the clamping screw of the terminal stud for locking three-phase ground line.
Compared with prior art, the utility model has the following advantages:
High and low pressure side in transformer cabinet installs this dry-type transformer grounding device respectively, be conducive to shortening ground distance, even high and low pressure side all installs earth connection, because there are 2 place's grounding copper bars, earth connection is installed comparatively light, be convenient to daily isolated operation, greatly improve operating efficiency, earth connection installing is also more attractive in appearance.Its fabrication and installation are simultaneously convenient, have good application prospect in hydroelectric plant.
