Abstract
The invention discloses an electric device abnormal current monitoring system which comprises a current mutual inductor, a signal converter connected with the current mutual inductor, a monitoring computer electrically connected with the signal converter and an alerter connected with the monitoring computer through signals. A single-chip microcomputer is internally arranged in the signal converter. According to the mode, the electric device abnormal current monitoring system can accurately conduct abnormal current monitoring on an operated electric device, the structure is simple, the operated electric device can be effectively protected, and a safety accident can be avoided.
Description
Technical field
The present invention relates to a kind of electrical equipment abnormal current monitoring system, in order to appliance working is carried out to the abnormal current monitoring.
Background technology
In some electrical works, if working current is crossed conference infringement electrical equipment, even security incident can occur, such as fire.Therefore need to carry out the abnormal current monitoring and send in time alerting signal appliance working, prompting be processed.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of electrical equipment abnormal current monitoring system; this electrical equipment abnormal current monitoring system can be carried out accurately abnormal current monitoring to appliance working; simple in structure, Protection electrical equipment, avoid the generation of security incident effectively.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of electrical equipment abnormal current monitoring system is provided, it comprise current transformer, with the signal converter of described current transformer series connection, with the supervisory control comuter of described signal converter electric connection and with described supervisory control comuter between the alarm that is connected of signal.
In a preferred embodiment of the present invention, the combination that described current transformer and the signal converter of connecting with described current transformer form is at least two groups.
In a preferred embodiment of the present invention, described signal converter is built-in with single-chip microcomputer.
The invention has the beneficial effects as follows: this electrical equipment abnormal current monitoring system can be carried out accurately abnormal current monitoring to appliance working, and simple in structure, Protection electrical equipment, avoid the generation of security incident effectively.
The accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of electrical equipment abnormal current monitoring system of the present invention.
In figure, the mark of each parts is as follows: 1, current transformer, 2, signal converter, 3, supervisory control comuter, 4, alarm.
Embodiment
Below will the technical scheme in the embodiment of the present invention be clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under the creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, electrical equipment abnormal current monitoring system of the present invention comprise current transformer 1, with the signal converter 2 of described current transformer 1 series connection, with the supervisory control comuter 3 of described signal converter 2 electric connections and with described supervisory control comuter 3 between the alarm 4 that is connected of signal.
Preferably, described signal converter 2 is built-in with the single-chip microcomputer (not shown).
Further, current transformer 1 is connected with the work loop of appliance working, send the electric current in the work loop of electrical equipment to signal converter 2, the single-chip microcomputer in signal converter 2 converts current signal the signal that supervisory control comuter 4 can identify to and sends this signal to supervisory control comuter 4.If the work loop current value that supervisory control comuter 4 carries out the analyzing and processing appliance working to these signals surpasses the current value that supervisory control comuter 4 is set, supervisory control comuter 4 sends alarm command to alarm 4, alarm 4 pipes and is reported to the police, and notifies the staff timely queueing problem.
Preferably, the combination that described current transformer 1 and the signal converter 2 of connecting with described current transformer 1 form is at least two groups, with the monitoring needs in a plurality of work loop of adapting to appliance working.
Be different from prior art, this electrical equipment abnormal current monitoring system of the present invention can be carried out accurately abnormal current monitoring to appliance working, and simple in structure, Protection electrical equipment, avoid the generation of security incident effectively.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes instructions of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
