Description

A kind of potential transformer burglar alarm
Technical field
The present invention relates to a kind of potential transformer burglar alarm.
Background technology
The theft protection for devices early warning such as existing three-phase electricity and transformer are to consist of collecting unit and main frame mostly, unit monitors circuit is transferred to main frame when abnormal, the same alarm of unit and main frame, but reporting to the police, main frame has individual defect, can only tell that staff is to report to the police in which road, and also must contrasting respective table, staff consults specified place corresponding to a certain road, efficiency in the extreme, if staff Bu electric substation, that does not just receive alerting signal, this just needs to wait in turn for 24 hours, and working strength is too large.
Summary of the invention
The present invention solves the existing technical matters of prior art, thereby can notify staff by short message mode when providing a kind of main frame to report to the police, and can determine accident particular location, cheap, the potential transformer burglar alarm that serviceability is good.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals:
A kind of potential transformer burglar alarm, comprise voltage sampling device, signal processing apparatus, transformer signal acquisition and processing apparatus, warning device and automatic short message alarming device, described signal processing apparatus comprises the first rectification filtering module, the first light-coupled isolation module, the first contrast module, the second rectification filtering module, the second light-coupled isolation module and the second contrast module, described voltage sampling device, signal processing apparatus, transformer signal acquisition and processing apparatus, warning device is connected successively with automatic short message alarming device, described the first rectification filtering module, the first light-coupled isolation module, the first contrast module, the second rectification filtering module, the second light-coupled isolation module and the second contrast module are provided with input end and output terminal.
As preferably, the input end of described the first rectification filtering module is connected with voltage sampling device, the output terminal of described the first rectification filtering module is connected with the input end of the first light-coupled isolation module, the output terminal of described the first light-coupled isolation module is connected with the input end of the first comparing module, and the output terminal of described the first contrast module is connected with transformer signal pickup assembly.
As preferably, the input end of described the second rectification filtering module is connected with voltage sampling device, the output terminal of described the second rectification filtering module is connected with the input end of the second light-coupled isolation module, the output terminal of described the second light-coupled isolation module is connected with the input end of the second comparing module, and the output terminal of described the second contrast module is connected with transformer signal pickup assembly.
The beneficial effect of potential transformer burglar alarm of the present invention is: because described potential transformer burglar alarm adopts automatic short message alarming device, the concrete all parts that is divided in signal processing apparatus, the associated parts of each parts are connected, when thering is main frame warning, can notify staff by short message mode, can determine accident particular location, the advantage cheap, serviceability is good.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the theory diagram of a kind of potential transformer burglar alarm of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
Consult shown in Fig. 1, the present invention adopts following technical scheme: a kind of potential transformer burglar alarm, comprise voltage sampling device, signal processing apparatus, transformer signal acquisition and processing apparatus, warning device and automatic short message alarming device, described signal processing apparatus comprises the first rectification filtering module, the first light-coupled isolation module, the first contrast module, the second rectification filtering module, the second light-coupled isolation module and the second contrast module, described voltage sampling device, signal processing apparatus, transformer signal acquisition and processing apparatus, warning device is connected successively with automatic short message alarming device, described the first rectification filtering module, the first light-coupled isolation module, the first contrast module, the second rectification filtering module, the second light-coupled isolation module and the second contrast module are provided with input end and output terminal.
The input end of described the first rectification filtering module is connected with voltage sampling device, the output terminal of described the first rectification filtering module is connected with the input end of the first light-coupled isolation module, the output terminal of described the first light-coupled isolation module is connected with the input end of the first comparing module, and the output terminal of described the first contrast module is connected with transformer signal pickup assembly.
