適用材料：

    主要適用于固體絕緣材料如：電線套管、樹脂和膠、浸漬纖維制品、云母及其制品、塑料薄膜、陶瓷、玻璃、絕緣漆、硫化橡膠、電纜紙、絕緣漆漆膜、硬質橡膠、紙板等絕緣介質在空氣或液體介質中，測量工頻（48~62Hz）或對應直流電壓下擊穿強度和耐電壓時間。適用于連續均勻升壓或逐級升壓的方式，對試樣施加交流/或直流，電壓直至擊穿，測量擊穿電壓值，計算試樣的擊穿強度；用迅速升壓的方法，將電壓升到規定值，保持一定的時間試樣不擊穿，定此時規定值為試樣的耐電壓值。

Applicable materials:

Mainly suitable for measuring the breakdown strength and withstand voltage time of solid insulation materials such as wire sleeves, resins and adhesives, impregnated fiber products, mica and its products, plastic films, ceramics, glass, insulation paint, vulcanized rubber, cable paper, insulation paint film, hard rubber, cardboard, etc. in air or liquid media at power frequency (48-62Hz) or corresponding DC voltage. Suitable for continuous and uniform boosting or stepwise boosting, apply AC/or DC voltage to the sample until breakdown, measure the breakdown voltage value, and calculate the breakdown strength of the sample; Using a rapid voltage increase method, raise the voltage to the specified value and maintain the sample without breakdown for a certain period of time. The specified value at this time is the withstand voltage value of the sample.

　　擊穿電壓也是評定絕緣油(包括變壓器油、電容器油、電纜油等)電氣性能的一項指標，可用來判斷絕緣油含水和其他懸浮物污染的程度，以及對注入設備前油品干燥和過濾程度的檢驗。

　　對清凈干燥的油施加一個逐漸升高的電壓時，在電壓的負會發射電子，當電子具有足夠能量時，可使油分子微化離解，于是整個離解過程隨電壓升高而加強，當達到某一個電壓后，會產生大量傳導電流而形成電弧，這種現象被稱為擊穿，此時的電壓被稱為擊穿電壓。若油中有水或固體物存在時，則會使擊穿電壓變小，這是由于水和固體物的導電性均比油大之緣故。運行油中的擊穿電壓低是變壓器工作危險的信號。

對于變壓器油國內外標準，規定的擊穿電壓一般在40-50 kV ，高的達60kV 甚至更多。

The breakdown voltage is also an indicator for evaluating the electrical performance of insulation oil (including transformer oil, capacitor oil, cable oil, etc.), which can be used to determine the degree of water content and other suspended matter pollution in insulation oil, as well as to inspect the degree of drying and filtration of oil before injection into equipment.

When a gradually increasing voltage is applied to clean and dry oil, electrons will be emitted at the negative end of the voltage. When the electrons have sufficient energy, they can cause the oil molecules to undergo micro dissociation. Therefore, the entire dissociation process strengthens with the increase of voltage. When a certain voltage is reached, a large amount of conductive current will be generated, forming an arc. This phenomenon is called breakdown, and the voltage at this time is called breakdown voltage. If there is water or solid in the oil, it will reduce the breakdown voltage because the conductivity of water and solid is higher than that of oil. The low breakdown voltage in the operating oil is a signal of the danger of transformer operation.

For domestic and foreign standards for transformer oil, the prescribed breakdown voltage is generally between 40-50 kV, with some reaching up to 60kV or even more.

絕緣介電強度試驗與絕緣電阻測試

絕緣介電強度試驗是在相互絕緣的部件之間或絕緣的部件與地之間,在規定時間內施加規定的電壓,以此來確定電機在額定電壓下能否安全工作,能否耐受由于開關、浪涌及其它類似現象所導致的過電壓的能力,從而評定電機絕緣材料或絕緣間隙是否合適。如果電機有缺陷,則在施加試驗電壓后,會產生擊穿放電或損壞。擊穿放電表現為飛弧(表面放電)、火花放電(空氣放電)或擊穿(擊穿放電)現象。過大的漏電流可能引起電參數或物理性能的改變 。

絕緣介電強度試驗與絕緣電阻測試是不能等同的。清潔、干燥的絕緣體盡管具有高的絕緣電阻,但卻可能發生不能經受絕緣介電強度試驗的故障;反之,一個臟的、損傷的絕緣體,其絕緣電阻雖然低,但在高電壓下也可能不會被擊穿。由于絕緣部件是由不同材料制成或是由不同材料合成的,它們的絕緣電阻各不相同。因此,絕緣電阻的測試不能代表對清潔度或無損傷程度的直接量度。但是,這種測試對確定高溫、潮濕、污物、氧化或揮發性材料等對絕緣特性影響程度是極為有益的 。

事實上,一臺由于過熱而使絕緣材料已經老化變脆的電機,其絕緣電阻仍可高達100MΩ,但卻無法通過絕緣介電強度試驗。絕緣電阻測試對絕緣材料受潮特別敏感,對絕緣材料老化則顯得力不從心。

絕緣介電強度試驗一般采用50Hz正弦波交流電,而絕緣電阻測試均采用直流電。

Insulation dielectric strength test and insulation resistance test

The insulation dielectric strength test is the application of a specified voltage within a specified time period between insulated components or between insulated components and ground, in order to determine whether the motor can operate safely at rated voltage and whether it can withstand overvoltage caused by switches, surges, and other similar phenomena, and to evaluate whether the insulation material or insulation gap of the motor is suitable. If the motor has defects, breakdown discharge or damage may occur after applying the test voltage. The breakdown discharge is manifested as flashover (surface discharge), spark discharge (air discharge), or breakdown (breakdown discharge) phenomenon. Excessive leakage current may cause changes in electrical parameters or physical properties.

The insulation dielectric strength test and insulation resistance test cannot be equated. Although clean and dry insulators have high insulation resistance, they may fail to withstand insulation dielectric strength tests; On the contrary, a dirty and damaged insulator, although its insulation resistance is low, may not be broken down under high voltage. Due to the fact that insulation components are made of different materials or synthesized from different materials, their insulation resistance varies. Therefore, the testing of insulation resistance cannot fully represent a direct measurement of cleanliness or undamaged degree. However, this type of testing is extremely beneficial for determining the degree of impact of high temperature, humidity, dirt, oxidation, or volatile materials on insulation characteristics.

In fact, a motor whose insulation material has aged and become brittle due to overheating can still have an insulation resistance of up to 100M Ω, but it cannot pass the insulation dielectric strength test. The insulation resistance test is particularly sensitive to moisture in insulation materials, and it is inadequate for aging insulation materials.

The insulation dielectric strength test generally uses 50Hz sine wave alternating current, while the insulation resistance test uses direct current.

電極和試樣

金屬電極應始終保持光滑、清潔和無缺陷。

注1：當對薄試樣進行試驗時，電極的維護格外重要。為了在擊穿時盡量減小電極損傷，優先采用不銹鋼電極。

接到電極上的導線即不應使得電極傾斜或其他移動或使得試樣上壓力變化，也不應使得試樣周圍的電場分布受到顯著影響。

注2：試驗非常薄的薄膜（例如：<μm厚)時,這些材料的產品標準應規定所用的電極、操作的具體程序和試樣的制備方法。

Electrodes and specimens

Metal electrodes should always be smooth, clean, and defect free.

Note 1: When testing thin specimens, electrode maintenance is particularly important. In order to minimize electrode damage during breakdown, stainless steel electrodes are preferred.

The wire connected to the electrode should not tilt or move the electrode or cause pressure changes on the sample, nor should it significantly affect the distribution of the electric field around the sample.

Note 2: Test very thin films (e.g.:< μ When the thickness is m, the product standards for these materials should specify the electrodes used, the specific procedures for operation, and the preparation method for the samples.

交直流實驗的切換

1）本儀器高壓輸出為交流電壓。直流的獲得方式為在原回路中串入高壓硅堆，使測試回路為脈動的直流電壓。實現的過程為：硅堆已經在高壓變壓器的高壓絕緣塔中，平時用一個短路桿把高壓硅堆短接。需要直流試驗時，取出短路桿，使高壓硅堆接入測試電路中，這時回路的電壓為脈動的直流電壓。

2）前面板直流交流選擇按鈕。該按鈕的狀態不能改變設備輸出的電壓性質。按下該按鈕，設備僅僅是把直流報警電路接入。指示用戶，當打開箱門時，您需要對高壓均壓球放電。轉動放電桿，使放電桿的端部銅球接觸高壓均壓球。建議用戶每次放電銅球接觸高壓均壓球時間大于五秒。

3）試驗的交直流電壓切換，主要取決于高壓絕緣塔中的短路桿是否取出。當取出短路桿時，高壓均壓球上的電壓為直流電壓，插入短路桿時，高壓均壓球上的電壓為交流電壓。

Switching between AC and DC experiments

1) The high-voltage output of this instrument is AC voltage. The method of obtaining direct current is to connect a high-voltage silicon stack in series in the original circuit, making the test circuit a pulsating direct current voltage. The implementation process is as follows: the silicon stack is already in the high-voltage insulation tower of the high-voltage transformer, and a short-circuit pole is usually used to short circuit the high-voltage silicon stack. When a DC test is required, remove the short-circuit rod and connect the high-voltage silicon stack to the test circuit. At this time, the voltage of the circuit is a pulsating DC voltage.

2) Front panel DC AC selection button. The status of this button cannot change the voltage nature of the device output. Pressing this button only connects the DC alarm circuit to the device. Instruct the user that when opening the box door, you need to discharge the high-voltage equalizing ball. Rotate the discharge rod so that the copper ball at the end of the discharge rod contacts the high-voltage equalizing ball. It is recommended that the user press the copper ball for more than five seconds each time it comes into contact with high voltage during discharge.

3) The switching of AC/DC voltage in the experiment mainly depends on whether the short-circuit rod in the high-voltage insulation tower is removed. When the short-circuit rod is removed, the voltage on the high-voltage equalizing ball is DC voltage, and when the short-circuit rod is inserted, the voltage on the high-voltage equalizing ball is AC voltage.

電氣強度測試(electric strength test)又稱耐壓測試。簡單點說，任何電氣設備都有一個絕緣強度，不同額定電壓的絕緣強度不一樣。當超過一定電壓等級后，設備的絕緣就會被擊穿。電氣強度測試就是看在給被測設備加一定的高電壓（可以參考IEC標準或者國標），看是否會導致擊穿。如果不擊穿，則通過，擊穿則說明不合格。

　　一般在設備出廠前做這個試驗，在現場可能僅僅是搖絕緣就可以了。另外，該試驗是破壞性試驗，一旦擊穿，不可修復。

　　電氣強度測試(electric strength test)又稱耐壓測試，是圍繞絕緣材料被擊穿后呈現出導體特性的特點,考察相關電參數的變化特征,以此判定絕緣材料是否被擊穿。

Electrical strength test, also known as voltage withstand test. Simply put, any electrical equipment has an insulation strength, and the insulation strength varies with different rated voltages. When the voltage level exceeds a certain level, the insulation of the equipment will be broken down. Electrical strength testing is to apply a certain high voltage to the tested equipment (can refer to IEC standards or national standards) to see if it will cause breakdown. If it does not break through, it passes. If it breaks through, it indicates that it is unqualified.

Usually, this test is conducted before the equipment leaves the factory, and on site, it may only be necessary to shake the insulation. In addition, this test is destructive and cannot be repaired once it is broken down.

Electrical strength test, also known as voltage withstand test, is a test that focuses on the characteristics of insulating materials that exhibit conductor characteristics after being broken down, examining the changes in relevant electrical parameters to determine whether insulating materials have been broken down
