Abstract
The utility model discloses an intelligent transformer. The intelligent transformer comprises a housing and a transformation device installed inside the housing. The transformation device is provided with a single-chip microcomputer, wherein the single-chip microcomputer is connected with an switching input, a nixie tube display, a fault alarm apparatus, an output circuit, an analog conversion circuit and a communication RS485 respectively; the output circuit is connected with a blower fan, an overtemperature tripping apparatus and an overtemperature alarm apparatus respectively; the analog conversion circuit is connected with a platinum resistor; and the overtemperature alarm apparatus is provided with a temperature control instrument. The overtemperature alarm apparatus can determine whether any abnormity occurs in the field through comparison between an actual temperature and an upper limit temperature. At the same time, the arranged overtemperature tripping apparatus can eliminate damage onto the transformer caused by over-high temperature. The fault alarm apparatus and the nixie tube display can display the location of any fault point and the type of a fault.
Description
Technical field
The utility model relates to transformer, relates in particular to a kind of intelligent transformer.
Background technology
In the prior art, transformer often breaks down, and needs to drop into manpower and overhauls, but because the technological means restriction need detect by test pencil and other coherent detection instrument, waste time and energy.
The utility model content
The technical problems to be solved in the utility model has been to provide a kind of intelligent alarm, intelligent automatic trip and has had the transformer of fault alarm.
For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of intelligent transformer, comprise shell body and be installed in the interior potential device of shell body, described potential device is provided with single-chip microcomputer, and this single-chip microcomputer connects switch input, charactron display, accident warning device, output circuit, analog conversion circuit, communication RS485 respectively.
Further, described output circuit connects blower fan, overtemperature tripgear, overtemperature alarm device respectively.
Further, described analog conversion circuit is connected with platinum resistance.
Further, described overtemperature alarm device is provided with temperature controller.
The utility model has the advantages that: the overtemperature alarm device can be by the comparison of actual temperature and ceiling temperature, judge whether the scene abnormal conditions occur, simultaneously, the overtemperature tripgear is set can be got rid of owing to the too high damage that transformer is caused of temperature, and accident warning device, charactron display, can where show the trouble spot, and belong to which kind of fault.
Description of drawings
Fig. 1 is the utility model structured flowchart.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, a kind of intelligent transformer, comprise shell body and be installed in the interior potential device of shell body, described potential device is provided with single-chip microcomputer 1, this single-chip microcomputer 1 connects switch input 2, charactron display 3, accident warning device 4, output circuit 6, analog conversion circuit 10, communication RS48511 respectively, described output circuit 6 connects blower fan 5, overtemperature tripgear 7, overtemperature alarm device 8 respectively, and described analog conversion circuit 10 is connected with platinum resistance 9.
In fault output circuit 6, use photoelectric coupled device, make output have higher electrical isolation and antijamming capability.Temperature sensor two ends in analog conversion circuit 10, and other local piezoresisters that use, the superpotential of absorption opposed polarity.Overtemperature alarm device 8 is provided with temperature controller, low in energy consumption, the advanced technology of this temperature controller, and perfect in shape and function, simple to operate, dependable performance can be the desirable supervising device of transformer in very abominable electromagnetic interference (EMI) or hot environment long-term stable operation.
The above only is preferred implementation of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope of patent protection of the present utility model.
