Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model one embodiment.
Detailed description of the invention
Combine accompanying drawing below by specific embodiment this utility model is described in further detail.
Referring to Fig. 1, shown in figure is a kind of voltage-withstand test instrument correcting device, in order to calibrate the resistance to electricity of measured object 4
Pressure situation, includes,
Base platform 1, it has platform base 12 and platform end face 11, described platform base has slider roller 6；
High-voltage capacitor 2, it is placed on described platform end face, and described high-voltage capacitor has capacitor high voltage end 21 and electric capacity
Device earth terminal 22, described high-voltage capacitor has capacitor end face and capacitor side, and described capacitor high voltage end is in described electricity
In container top surface, described capacitor grounding end is on described capacitor side；
High-tension transformer 3, it is placed on described platform end face and adjacent to described high-voltage capacitor, described high-tension transformer
There is transformator outfan 31, transformer grounding end 32, transformer high-voltage tail end 34 and transformer inputs 33；And,
Discharging rod 5, it has discharging rod earth terminal 51 and discharging rod discharge head 52；
Wherein, described capacitor grounding end is electrically connected with described transformer high-voltage tail end mutually by the first connecting line 71,
Described discharging rod earth terminal is electrically connected with described transformer grounding end mutually by the second connecting line 72, the first of described measured object
End is electrically connected with described transformer grounding end mutually by the 3rd connecting line 73, and described capacitor high voltage end passes through the 4th connecting line 74
Being electrically connected with mutually with described transformator outfan, described capacitor high voltage end is by the 5th connecting line 75 and the second of described measured object
End is electrically connected with mutually.Discharging rod is to there being a camera bellows, and discharging rod is in camera bellows.Discharging rod discharges in camera bellows.
Using method is as follows:
1. before instrument uses, it is necessary to first voltage-regulation knob is transferred to zero-bit and closes power supply, then under direct current mode
Test: be connected with transformer high-voltage outfan high-pressure connection line by the high-pressure side of high-voltage capacitance, extracts exchange conducting rod；Become
The ground connection termination measured object shell of depressor or low side, the other end of the High voltage output termination measured object of transformator.
Switch on power after the most all installing.
3. set leakage current higher limit: select leakage current preset value, be allowed to the leakage current higher limit phase with measured object requirement
Corresponding.
4. setting voltage value: select the magnitude of voltage meeting measured object requirement to carry out preset.
5. connect measured object: close power supply, when testing under direct current mode, be completed cutoff high and close power supply
After, it is necessary to discharge with discharging rod.After discharge off to be waited until, just can carry out next step operation.Otherwise, connecting line still has high pressure
Security incident can be caused.In the case of determining that output voltage is zero, the end of high-tension transformer ground connection is connected measured object, then
The test clip of the high-voltage output end of high-tension transformer is received measured object.Forbid to connect measured object in the case of not discharging, no
Then can cause life danger.
6. " manual " test:
A. pressing " startup " button, " test " display lamp is bright, and voltage is upgraded to preset value automatically, makes test voltage be added to tested
On thing.
B. after being completed, press the Reset button, cut off output voltage.
If the electric current c. flow through in measured object is more than the leakage current value set, instrument judges that measured object " superleak " will be certainly
Dynamic cut-out output voltage, and send " superleak warning ", " superleak " display lamp is bright, presses the Reset button, can remove alarm signal
Number.
7. " regularly " test:
A. press intervalometer, the required testing time is set.
B. press " startup " button, when magnitude of voltage rises to preset value, then press " start by set date " button, when intervalometer is determined
Time is up, and test voltage automatically cuts off, and measured object has passed through test, then instrument does not produce superleak alarm signal.Test terminates
After, press the Reset button.
C. as produced " superleak " signal in test process, represent that measured object, can by the Reset button not over test
Remove alarm signal.
The use of discharging rod
1. first the earth terminal of discharging rod is connected with the earth terminal of high-tension transformer before test.
2. when testing under direct current mode or alternating-current measurement capacitive load, after being completed cutoff high closedown power supply,
Must discharge with discharging rod.Closing power supply, slowly contact high-pressure side with the discharge head (spherical) of discharging rod, time of contact is 30s.
The most then the earth terminal of discharging rod and high-pressure side being collided, it is good to be brought into contact with, and the time of colliding is 10s.
Note: when electric discharge, the earth terminal of discharging rod, earth lead slowly should lean on the distance of high-pressure side at more than 0.5 meter
Nearly high-pressure side.
Proof voltage tester is on the basis of absorbing, digesting international advanced voltage-withstand test, in conjunction with the reality of the numerous user of China
Border service condition improved, perfect.Total phenotype Hi-pot Tester, test voltage, leakage current are tested and the time is numeral
Display, cutting off electric current the most arbitrarily can set according to different safety criterion demands different with user, the more abundant practicality of function, and
And the actual value of measured body leakage current can be reflected by leakage current display and compare like product different batches or different manufacturers product
Pressure quality degree in product, it is ensured that product safety performance is perfectly safe.
Below only have expressed embodiment of the present utility model, it describes more concrete and in detail, but can not therefore and
It is interpreted as the restriction to utility model patent scope.It should be pointed out that, for the person of ordinary skill of the art, not
On the premise of departing from this utility model design, it is also possible to making some deformation and improvement, these broadly fall into guarantor of the present utility model
Protect scope.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
