Description
Technical field
The present invention relates to measure the apparatus and method insulated between spininess aviation plug pin.
Background technology
Spininess aviation plug energy fast and easy dismounts many electrical cables, is widely used in modern electrical control field,
To ensure to be insulated between electrical connection, insulated using insulant such as rubber between aviation plug pin, after longtime running, inserted
Between head insulant easily because situations such as aging, high temperature insulation decline, can in operation cause short to a certain extent when insulation declines
The accidents such as road, it is therefore desirable to insulate between periodic measurement pin.
Insulate between measurement pin at present, the side measured one by one between pin to be measured is directly put using two test pencils of insulation meter
Method.So that 6.6KV switchs 36 pin plugs as an example, need to measure one by one around it and shell during No. 1 pin of measurement, totally 5 times, whole pins
Measurement needs altogether 126 times.And insulate between pin reading and offer historical comparison to correctly obtain, it is desirable to 500V is used in insulation between every pin
Reading after measurement 1 minute, measure a piece pin and measure next pin will move before the test pencil of insulation meter, by electrical safety operation rule
Model needs first to disconnect insulation apparent source to prevent band electromigration pin from causing electric arc to cause equipment damage, then moves on to next pin and connects again
Logical insulation apparent source is time-consuming at least about 10 seconds, time-consuming about 1 point is so measured every time 10 seconds, completes an aviation plug measurement needs
More than 2 hours, move pins and switching insulation meter power operation 126 times.It can be seen that the measurement side insulated between existing spininess aviation plug pin
Pendulous frequency needed for method is more, speed is slow, personnel labor intensity is big, is also easy to omit the measurement of some pins, therefore exists improved
It is necessary.

Specific embodiment
In order to be more clearly understood to the technical characteristic of the present invention, purpose and effect, now compare accompanying drawing and describe in detail
The specific embodiment of the present invention.
A kind of method insulated between quick measurement spininess aviation plug pin, including herein below：
PLC is provided with a main bus-bar 100, from bus 101, for measuring the measuring instrumentss 103 insulated between pin
Be arranged at main bus-bar 100 and between bus 101, main bus-bar 100 be equivalent to existing use insulation meter or ten thousand from bus 101
With two test pencils of table.Spininess aviation plug to be measured is connected in PLC by corresponding female aviation plug, spininess boat
Arbitrary connecting plug needle on blind plug derives two connecting lines by female aviation plug, wherein one is corresponding with main bus-bar 100, it is another
Bar is corresponding with from bus 101；Additionally, female aviation plug also derives an earth lead corresponding with spininess aviation plug shell, connect
Ground wire is corresponding with from bus 101.
During measurement, PLC turns on front plug pin with the corresponding connecting line of main bus-bar 100, and remaining connecting plug needle is then
Conducting with from the corresponding connecting line of bus 101, while earth lead also with turn on from bus 101, thus draw in PLC
Insulate numerical value between the pin of front plug pin.
As shown in figure 1, a kind of device corresponding with preceding method, described device is including PLC and is connected thereto
Main bus-bar 100, from bus 101, measuring instrumentss 103, wherein the measuring instrumentss 103 be arranged at main bus-bar 100 with from bus
Between 101, described device also includes the female aviation plug matched with spininess aviation plug, and female aviation plug is provided with two groups
The connecting line matched with each connecting plug needle on spininess aviation plug, each bar connecting line in one of which is controlled respectively by PLC
System with the folding of main bus-bar 100, each bar connecting line in another group by PLC control respectively with from the folding of bus 101；In addition
Be additionally provided with earth lead corresponding with spininess aviation plug shell on female aviation plug, the earth lead with connect from bus 101
Connect.
Be in accompanying drawing by taking the aviation plug of 36 pins as an example, in figure numeral 1,2,3 ... 36 represent be each connecting plug needle phase
Pin number is answered, what E was represented is the shell of spininess aviation plug, when insulation between testing needle, in peripheral connecting plug needle except wanting
Test its with the insulation values of each connecting plug needle around outside, in addition it is also necessary to test its insulation values between shell, shell is in itself need not
Be test for, thus its earth lead be connected always from bus 101.
All pins are drawn out on PLC contact by a female aviation plug, are divided into two groups, when needing measurement 1
When pin insulate, by the junction closure conducting main bus-bar 100 above No. 1 pin, other all pins are turned on from bus 101（State is as schemed
2）.Connect insulation meter start measurement, by PLC can intuitively find out when pre-test pin number and its between each pin of periphery
Insulation values.
And to avoid causing insulation meter current interruptions electric arc occur with electrically disconnected No. 1 pin after measuring, while also to solve resolution
Opening insulation apparent source needs the problem of operation bidirectional, using first by No. 2 pins from disconnecting from bus 101（Now No. 1 pin is still maintained
Insulation meter current turns ON）, the method for then putting into the transition of main bus-bar 100（As shown in Figure 3）.Master has been put in No. 2 pins
Bus 100 disconnects again No. 1 pin after entering after measurement（As shown in Figure 4）, so in disconnection process the electric current of insulation meter not in
It is disconnected, will not starting arc, without the need for cut-out insulation apparent source.By PLC contacts, in order action is completed aforementioned handoff procedure, and the time is little
In 0.1 second.The reading of insulation meter only can short-time fluctuations, measure 1 minute state subsequently into No. 2 pins, will not cause and misread number.
Whole measurement process is automatically performed by PLC switching, and operator is only needed to every one minute record once
Reading, without moving indicator again, does not have that repeatedly measurement is omitted yet, and the new measuring method has the advantage that：Measurement
Number of times is few, and pendulous frequency is reduced to original about 1/4 by two groups of bus combinations, and which reducing needs the data volume of record；
Quickly, the measurement for only completing to need more than 2 hours originally with 36 minutes, script one-shot measurement terminate after 10 seconds transition times because
Being switched fast for PLC and cancel；Automatic measurement reduces labor intensity, and operator switch up to a hundred indicators without the need for manual, only
Need record data；Programme-control can avoid omitting, and pendulous frequency originally excessively easily causes omission.
The D.C. resistance that the method, device extend also to measure between some pins judges conduction, for example, measure 1-2 pins
Between conduction, controllable two metering pin 1-2 to be measured put into main bus-bar 100, from bus 101, and other pins disconnect, then measurement
Table changes circuit tester into and directly hinders the quick inspection that shelves are capable of achieving spininess conduction.
The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to, for the skill of this area
For art personnel, the present invention can have various changes, combination and change.It is all within the spirit and principles in the present invention, made
Any modification, equivalent substitution and improvements etc., should be included within scope of the presently claimed invention.
