Abstract
The invention discloses a testing device for spark voltage of electrolyte under non-critical state. The testing device is provided with a 1000V-T-V tester, a beaker, high-voltage electrolyte and an electrode foil. The middle part of the electrode foil is wrapped with a plurality of layers of insulation tapes, and the insulation tapes separate the electrode foil into a suspending area and a liquid precipitating area. The operation steps are as follows: 1) the suspending area of the electrode foil is connected with the 1000V-T-V tester, and an ammeter and a voltmeter are connected between the electrode foil and the 1000V-T-V tester in series; 2) a proper amount of high-voltage electrolyte is injected into the beaker according to the height of the liquid precipitating area of the electrode foil; 3) the electrode foil is placed and suspended in the electrolyte, and half of the insulation tape is immersed in the electrolyte; and 4) a power supply is switched on to input current of 5mA-10mA, and the voltage of the sparks of the electrolyte is tested. The safe surge voltage of the product at high temperature can be ensured by the variation of the sparks of the electrolyte at each temperature section, and the stability of the product at high temperature is ensured.
Description
Technical field
The present invention relates to a kind of testing apparatus and method of testing that is used for electrolytic solution flash over voltage under non-critical state.
Background technology
The existing test method of flash over voltage down is as follows, as shown in Figure 1, for than common testing methods, the double anode test, but because this method is to test under normal conditions, there are many unreasonable parts.When being its test, test anode strip and electrolytic solution surface of contact place knocking are in air, easily ionizable, when testing simultaneously, the bubble that test produces makes the liquid level of electrolyte fluctuation, even splashes liquid, the earthquake that do not stop of test electrode scope like this, show as electrode on the mechanism and change into asynchronously, existing test result is flicker artifacts numerical value.
As shown in Figure 2, it among the figure single anode test, the same problems such as vacation looks like of testing that exist, reason is that foil electrode fixed by the organic glass clamping plate, the slit, edge can make tested area fluctuation equally, change in the edge part equally asynchronous, and easily edge ionization flicker, same test value be that vacation is as numerical value.
Summary of the invention
The objective of the invention is to address the aforementioned drawbacks, and provide a kind of testing apparatus and method of testing that is used for electrolytic solution flash over voltage under non-critical state, thereby electrolytic solution is safe surge voltage under the hot conditions of the variation assurance product of flashing point under each temperature section, guarantees the stability of product under the hot conditions.

Described electrode foil plate is fine aluminium matter goods, and its specification is 50*10mm, and the heavy liquid zone of electrode foil plate is 40*10mm.
The width of described insulating tape is 15～25mm.
A kind of method of testing that is used for electrolytic solution flash over voltage under non-critical state, operation steps:
1), the suspension area of electrode foil plate connects the 1000V-T-V tester, be in series with reometer between electrode foil plate and the 1000V-T-V tester and be parallel with voltage table;
2), according to the height of the heavy liquid zone of electrode foil plate, beaker injects an amount of high-pressure electrolysis liquid;
3), put into electrode foil plate and hang on electrolytic solution, electrolytic solution impregnated in 1/2 position of insulating tape;
4), energized is failed 5mA～10mA, test electrolytic solution flashing point voltage.
Beneficial effect of the present invention:
The present invention is at the middle part of electrode foil plate wrapped multiple insulating tape, use insulating tape spaced electrodes paillon foil to be suspension area and heavy liquid zone, in test, electrolytic solution impregnated in the heavy liquid zone of electrode foil plate, the suspension area of effectively isolating electrolytic solution contact electrode paillon foil, it is false as numerical value having avoided the ionization flicker to cause test value.
Method of testing of the present invention: energized, test electrolytic solution flashing point voltage, defeated 5mA～10mA, the electrolytic solution flashing point change in voltage under the test different temperatures is as 30 ℃, 85 ℃, 95 ℃, 105 ℃, 130 ℃, 150 ℃ or the like, with reference to accompanying drawing 5.
