Abstract
The utility model discloses a transformer partial-discharge detection apparatus, which is used for electric power detection. The apparatus includes a receiving antenna which is arranged in a housing, and an outgoing line joint connected with a signal cable of the receiving antenna is arranged at the side of the housing. According to the utility model, partial-discharge signals of the transformer can be detected through the gap on the base, and the water-proof and dust-proof functions required by outdoor detections are achieved. Besides, the apparatus has the advantages of simple structure, low cost, and relatively high practical value, and the structure is easy to cooperate with conventional standard transformers, providing convenient installation.
Description
Technical field
The utility model relates to the electric power pick-up unit, relates in particular to a kind of local discharge detection device that is used for transformer base slit.
Background technology
Transformer is the important composition in the electric system, and the duty of transformer is directly connected to the lasting function of corresponding line and energy consumption index of electric energy or the like, and therefore the monitoring for transformer just seems still for important.Yet practical Related product and scheme but also do not appear in the shelf depreciation status detection field in transformer base slit.
Summary of the invention
The utility model provides a kind of partial discharge of transformer pick-up unit in order to address the above problem, and it can be realized shelf depreciation status detection in the transformer through surveying the signal that local discharge signal radiates in the transformer.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: a kind of partial discharge of transformer pick-up unit, comprise receiving antenna, and said receiving antenna is arranged in the shell; The shell side is provided with pinout connector, and pinout connector connects the signal cable of receiving antenna.
Said shell is a rectangular box, and its trailing flank opens wide, and all to opening wide reverse the extension, pinout connector is arranged on the box portion right side in the above and below.
Said receiving antenna is inboard through the cavity that silica gel sticks on shell.
Middle part, said shell side is provided with signal cable and draws window, and said pinout connector is drawn window through signal cable and is fixed on the shell.
Have operation window near top, pinout connector place above the said box body, the airtight cover plate that is combined with in operation window top.
Said airtight cooperation refers to be provided with the silicone rubber pad that one deck covers said operation window between cover plate and the shell, and cover plate is connected through screw with shell.
Rear end, said box body above and below is equipped with the bolt hole.
A kind of partial discharge of transformer pick-up unit of the utility model comprises receiving antenna, and said receiving antenna is arranged in the shell, and the shell side is provided with pinout connector, and pinout connector connects the signal cable of receiving antenna.It can satisfy the waterproof and dustproof function of outdoor monitoring requirement through base slit monitoring partial discharge of transformer signal, and is simple in structure, with low cost, have higher utility, is prone to and existing standard specification transformer coupling in structure, easy for installation.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation:
Fig. 1 is the utility model structural representation;
Fig. 2 is the sectional structure synoptic diagram of Fig. 1.
Embodiment
With reference to Fig. 1, shown in Figure 2, a kind of partial discharge of transformer pick-up unit comprises receiving antenna 4, and said receiving antenna 4 is arranged in the shell 3, and shell 3 sides are provided with pinout connector 6, and pinout connector 6 connects the signal cable of receiving antenna 4.
Said shell 3 is a rectangular box, and its trailing flank opens wide, and all to opening wide reverse the extension, pinout connector 6 is arranged on the box portion right side in the above and below.
Said receiving antenna 4 is inboard through the cavity that silica gel sticks on shell (3).
Middle part, said shell 3 sides is provided with signal cable and draws window, and said pinout connector 6 is drawn window through signal cable and is fixed on the shell 3.
Have operation window near top, pinout connector 6 place above the said box body, the airtight cover plate 2 that is combined with in operation window top.
Said airtight cooperation refers to be provided with the silicone rubber pad 1 that one deck covers said operation window between cover plate 2 and the shell 3, and said cover plate 2 is connected through screw 5 with shell 3.
Rear end, said box body above and below is equipped with the bolt hole.
Concrete like Fig. 1, shown in Figure 2, a kind of partial discharge of transformer pick-up unit embodiment, the silica gel of the specific proportioning of receiving antenna 4 usefulness stick on the sidewall cavity inboard of shell 3; The sidewall housing width of shell 3 is 80mm, opens the signal cable of 15mm*20mm at the medium position of receiving antenna 4 and draws window; Signal cable is drawn from pinout connector 6; Shell 3 is opened the operation window of 50mm*80mm on pinout connector 6 tops, cover the thick silicone rubber pad of 2mm 1 on the operation window and realize waterproof, covers cover plate 2 on the silicone rubber pad 1, compresses the sidewall cavity sealing that silicone rubber pad 1 is realized shell 3 through screw 5.
During use, earlier. with shell 3 through on four external flanges that are bolted to transformer housing and base boundary; Again the signal extension line on the receiving antenna 4 is drawn out to pinout connector 6 through operation window; Then. behind the fixed signal cable, silicone rubber pad 1 is installed on operation window, is guaranteed seamless sealing; At last. pressing plate is compressed silicone rubber pad through set bolt, guarantee the water-proof function of signal cable.
The utility model through the slit of transformer and its base, is surveyed the signal that local discharge signal radiates in the transformer, realizes shelf depreciation status detection in the transformer.
The above-mentioned preferred embodiment that is merely the utility model, all structure replacement or improvement of making on this basis all surely belong to the protection domain that falls into the utility model.
