Description
Technical field
The utility model is related to a kind of Substation secondary circuit fault automatic detection alarm device, and which belongs to fault detect neck
Domain.
Background technology
Substation secondary circuit fault traditional approach is that universal meter measures potentiometry, is exactly electric with general-purpose table segmenting amount loop
Position, if there is positive and negative 110V current potential over the ground and can determine whether that loop, for path, is otherwise open circuit in loop.This kind of mode is applied to loop
Powered or uncharged state in permanent fault, i.e. loop, if loop occurs " flash " or " dodge and close " state, universal meter is measured
Rule cannot be suitable for.
Utility model content
Technical problem to be solved in the utility model there is provided one kind and can realize loop generation flash or dodge conjunction state
When automatic detection record the Substation secondary circuit fault automatic detection alarm device of loop on off operating mode.
The utility model is adopted the following technical scheme that：
A kind of Substation secondary circuit fault automatic detection alarm device, it include single-chip microcomputer, data storage, interrupt number
According to display touch-screen, signal acquisition circuit and loudspeaker Y；The signal acquisition circuit includes LED and protection electricity
Two ends after resistance R, the LED and the parallel connection of protective resistance R are connected on the two ends of tested secondary circuit, and the parallel connection
Two ends afterwards are connected with the signal input part of single-chip microcomputer, the corresponding output end connection loudspeaker Y of the single-chip microcomputer；The monolithic
The respective data transfer interface of machine connects data storage respectively and interrupts data display touch-screen.
The beneficial effects of the utility model are as follows：
The utility model devises Substation secondary circuit fault automatic detection alarm device, is mainly characterized by adopting monolithic
Machine Microsecond grade detection rates realize the detection record of loop " flash " or " dodge and close " state；If secondary circuit is divided into multistage,
Each section of loop boundary is respectively provided with device record loop " point, close " state, then can determine whether abort situation, be to exclude in time therefore
Barrier provides reference frame.Using data storage record secondary circuit " flash " or the time of " dodge and close ", abnormal information note is realized
Record inquiry.
The utility model is realized to Substation secondary circuit on the premise of each equipment of operating transformer station is not affected
Fault automatic detection, provides foundation for being accurately positioned fault loop.For many segmentations secondary circuit, examined using multiple stage fault automatically
Measuring alarming device joint searches fault loop, and effect becomes apparent from.This device saves substantial amounts of manpower and searches fault time, with
When do not affect charging equipment normally to run, to substation safety run there is provided powerful guarantee.
Description of the drawings
Fig. 1 is structural principle block diagram of the present utility model.
Specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings 1 and specific embodiment
Clear, complete description is carried out to utility model.
As shown in figure 1, the present embodiment includes single-chip microcomputer, data storage, interrupts data display touch-screen, signals collecting electricity
Road and loudspeaker Y；The signal acquisition circuit includes LED and protective resistance R, the LED and
Two ends after the parallel connection of protective resistance R be connected on the two ends of tested secondary circuit, and the parallel connection after two ends and single-chip microcomputer signal
Input is connected, the corresponding output end connection loudspeaker Y of the single-chip microcomputer；The respective data transfer interface of the single-chip microcomputer divides
Lian Jie not data storage and interruption data display touch-screen.
The present embodiment devises Substation secondary circuit fault automatic detection alarm device, is mainly characterized by adopting single-chip microcomputer
Microsecond grade detection rates realize the detection record of loop " flash " or " dodge and close " state；If secondary circuit is divided into multistage, each
Duan Huilu boundary is respectively provided with this device record loop and " divides, closes " state, then can determine whether abort situation, be to fix a breakdown in time
Reference frame is provided.Using data storage record secondary circuit " flash " or the time of " dodge and close ", abnormal information record is realized
Inquiry.
The present embodiment is realized to Substation secondary circuit event on the premise of each equipment of operating transformer station is not affected
Barrier automatic detection, provides foundation for being accurately positioned fault loop.For many segmentations secondary circuit, using multiple stage fault automatic detection
Warning device joint searches fault loop, and effect becomes apparent from.The present embodiment saves substantial amounts of manpower and searches fault time, with
When do not affect charging equipment normally to run, to substation safety run there is provided powerful guarantee.
The operation principle of the present embodiment is as follows：
By two ends of signal acquisition circuit to be connected on the two ends of tested secondary circuit, light using in signal acquisition circuit
Diode (LED) senses that secondary circuit occurs " flash " or " dodge and close " state, when there is " flash " or " dodge and close ", tested secondary
The two ends in loop can produce the pressure reduction change of moment, and this pressure reduction change is transmitted to single-chip microcomputer after being sensed by LED,
And record in data storage, for subsequent query, while LED can be produced flashing, remind inspection personnel's note
Meaning.Meanwhile, interrupt data display touch-screen and can show that abort situation showing there occurs " flash " or " dodge and close " state, and pass through
Interrupting data display touch-screen carries out human-computer interaction with single-chip microcomputer, and such as query history records or carry out initial setting up.Additionally, root
According to logic judgment in single-chip microcomputer, when " flash " or " dodge and close " state occurs to exceed early warning value in ad-hoc location or occurrence number,
Drive the speaker Y is reported to the police by single-chip microcomputer.
Finally it should be noted that：Above example only in order to the technical solution of the utility model to be described, rather than a limitation；
Although being described in detail to the utility model with reference to the foregoing embodiments, it will be understood by those within the art that：
Which still can be modified to the technical scheme described in previous embodiment, or which part technical characteristic is equal to
Replace；And these modifications or replacement, do not make the essence of appropriate technical solution depart from the utility model embodiment technical scheme
Spirit and scope.
