It is that specific embodiment described herein is merely to illustrate and explains the utility model embodiment, is not limited to this reality
Use new embodiment.
In the utility model embodiment, in the case where not making conversely explanation, the noun of locality that uses as " it is upper and lower, left,
It is right ", " inside and outside ", " remote, near " refer to the direction of refer to the attached drawing, therefore, use direction term is for illustrating not to be to limit this
Utility model.
Fig. 1 shows a kind of structure diagram for circuit fault detecting apparatus that the utility model embodiment provides, such as Fig. 1
Shown, which can include busy relay and electric voltage exception protector, and the coil of the busy relay is connected by wiring
It is connected in detected circuit, wiring both ends connect the output terminal and the electricity that the detected circuit is tested any component in section respectively
The zero curve of road power supply, the normally-closed contact of busy relay is connected with electric voltage exception protector to be connected on external power supply.
If the test section in detected circuit does not occur the busy relay normally-closed contact short time during being tested
Disconnect, the situation that electric voltage exception protector does not trip, then show that the test section without flash trouble point, can continue to test remainder
Circuit；If there is busy relay normally-closed contact in the test section in detected circuit during being tested separated in short-term
Situation, electric voltage exception protector is after the disconnection of busy relay normally-closed contact, due to circuit voltage where electric voltage exception protector
Cataclysm, electric voltage exception protector tripping, then show that the test section has flash trouble point.
Electric voltage exception protector can be pressure-failure protector or breaker in embodiment.Test section in detection circuit into
During row test, if there is busy relay normally-closed contact situation separated in short-term, pressure-failure protector or breaker are jumped
Lock.
Fig. 2 shows a kind of connection diagram for circuit fault detecting apparatus that the utility model embodiment provides, such as Fig. 2
Shown, detected circuit is relay control circuit, which includes relay coil Y, which also has multiple normal
Closed contact N1, N4, normally closed button N2, is delayed and disconnects normally-closed contact N3 and travel switch normally-closed contact N5；It is and multiple normally closed tactile
Point is connected and is connected on circuit power；The detected circuit further includes multiple wire connection terminal a1~a12, is separately positioned on above-mentioned more
Input terminal and output terminal of a normally-closed contact both ends as normally-closed contact, are actually considered as wire connection terminal.In detected circuit
When there is relay flash failure, first detect whether as relay Y faults itselfs, in the case of definite relay Y is normal,
Start whether normally-closed contact in detection circuit flash failure (some component or wiring appearance in namely tested section occurs
Voltage decline abruptly).The coil of busy relay 1, is connected in detected circuit by wiring, and wiring both ends connect quilt respectively
The N lines of the output terminal of any normally-closed contact and circuit power in detection circuit, the busy relay should be selected and relay Y mono-
Cause or similar performance；The normally-closed contact of busy relay 1 connects with electric voltage exception protector and concatenates external power supply.For it is quick really
Determine flash abort situation, be averaged according to the quantity of component in circuit or the circuit is divided into two parts by approximate be averaged, should in Fig. 2
Relay control circuit includes 5 normally-closed contacts, one end of 1 winding wiring of busy relay can be connected a5, the other end
Connect the N lines of the circuit power.
The problem of a2~a5 sections of detection whether there is flash failure first：
If the 1st, there is phenomenon separated in short-term, electric voltage exception protection in the normally-closed contact of detection-phase busy relay 1
Device 2 and voltage cataclysm in the series circuit where the normally-closed contact of busy relay 1, the tripping of electric voltage exception protector, then judge
A2~a5 sections of normally-closed contact transfers the wiring being connected on wire connection terminal a5 in wire connection terminal a3 there are flash trouble point
On, continue whether a2~a3 sections of normally-closed contact of detection phenomenon separated in short-term occurs, if it is detected that a2~a3 sections normally closed
There is phenomenon separated in short-term in contact, and the tripping of electric voltage exception protector, judging a2~a3 sections, there are flash trouble point, quick dimension
Continue flash trouble point investigation after repairing a2~a3 sections of flash trouble point.After excluding a2~a3 sections there are flash trouble point
The wiring being connected on wire connection terminal a3 is transferred on wire connection terminal a5 again, judges that a4~a5 sections whether there is flash failure
Point.
If the 2, not occurring separated in short-term in the normally-closed contact of detection-phase busy relay 1, electric voltage exception protector is not
Tripping, then judge that a2~a5 sections of normally-closed contact is normal, and the wiring being connected on wire connection terminal a5 is transferred in wire connection terminal a9
On, it is separated in short-term in a2~a9 sections of normally-closed contact appearance of detection, in the case that electric voltage exception protector trips, due to determining
A2~a5 sections of normally-closed contact is normal, if the a2~a9 sections of normally-closed contacts for occurring busy relay 1 in detection-phase are interrupted in short-term
Open, the tripping of electric voltage exception protector, judges flash trouble point at a5~a9 section, and so on constantly reduce detection range up to complete
Into the flash fault detect of all normally-closed contacts.
In embodiment, can also be by setting electric voltage exception protector auxiliary contact 3, the auxiliary contact one direct current of series connection
Working power 4, while the auxiliary contact and 2 state synchronized of electric voltage exception protector, for by electric voltage exception protector 2
Real time status information is sent to the monitor 5 of monitoring client.Specifically, if busy relay 1 detection-phase occur testing after
Electric voltage exception protector 2 trips after 1 normally-closed contact of electric appliance disconnects, and electric voltage exception protector auxiliary contact 3 protect electric voltage exception
The tripping of device 2 information is sent to monitor 5, and the output of monitor 5, which is alarmed, simultaneously carries out failure logging.
In embodiment, more set detecting devices can be set, busy relay is connected to by wiring respectively detected
In circuit, the component of each busy relay detection is incremented by one by one；For example, the first busy relay be used for detection circuit a2~
A4 sections, the second busy relay is used for detection circuit a2~a8, and so on, set multiple busy relays to detect respectively accordingly
Component, and by the way that each busy relay testing result progress comparison of combined being judged, the short time can investigate flash failure
Point position, can save the replacement connection point terminal of single busy relay, the time repeatedly tested, and improve investigation efficiency.
