50KV絕緣介電強度試驗機  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 。

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

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.

Gas dielectric breakdown

Under the action of an electric field, gas molecules collide and ionize, leading to penetrating discharge between electrodes. There are many influencing factors, mainly including the applied voltage, the shape of the electrode, the properties and state of the gas, etc. Common breakdown of gas media include DC voltage breakdown, power frequency voltage breakdown, high gas voltage breakdown, impulse voltage breakdown, high vacuum breakdown, negative gas breakdown, etc. Air is a good gas insulation material, with high ionization and breakdown field strength, After breakdown, the insulation performance can be quickly restored, and it is not flammable, explosive, aging, or corrosive, so it is widely used. To provide a design basis for the air gap distance of high-voltage transmission lines or substations (how high the high-voltage transmission lines should be from the ground), a power frequency breakdown test with a long air gap is required

Structural principles and performance characteristics:

This equipment mainly consists of: step-up system (high-voltage transformer), measurement system, A/D converter, discharge system, electrodes, oil tank, electrode positioning frame, computer data processing system, software, etc

Computer - A/D converter - Measurement control system - Voltage regulation device - Booster transformer - Sample

The high-voltage transformer mainly generates the DC voltage required for the sample,

The voltage regulator is used to regulate the input voltage of the step-up transformer to generate the input voltage required for high voltage,

Voltage measurement is mainly measured from the measurement end of the high-voltage transformer, and the measurement end and high-voltage end of the high-voltage transformer are linear,

The discharge system automatically discharges after the experiment is completed to avoid the harm of discharge to human health;

Security measures:

This instrument has multiple protective measures to ensure the personal safety of operators

（1）Door limit protection: Do not close the door, even if the power point experiment starts, the device has no response, and the software has a warning that the safety door is not closed.

（2）Voltage zeroing protection: If there is a sudden power outage during the experiment, it will automatically return to the zero position after the next startup, ensuring that the initial voltage is

（3）At zero position

（4）Termination voltage protection: The termination voltage can be set through software to ensure that if there is an abnormal rise to the specified voltage during the boosting process,

（5）Automatically terminate and reset to zero

（6）High voltage mechanical limit: If the software system loses control, the voltage continues to rise and automatically returns to zero after reaching the high voltage limit

（7）If the fault is not detected after breakdown, data is collected through an overcurrent protector to ensure that the voltage automatically zeros out

（8）There is a high-voltage indicator light, and by observing the status of the indicator light, it can be determined whether the boost is actually in the zero position or not

（9）If conducting experiments for a long time, in order to ensure the good operation of the equipment, a transformer exhaust port should be left on the equipment to ensure the good operation of the transformer,

（10）Increase service life

（11）If there is any odor or combustion or smoke in the sample during the experiment, it can be eliminated through the exhaust system.

（16）End of experiment discharge protection

Notes:

This instrument is a high-voltage testing equipment, and the following points must be noted when using it

1. The instrument should have an independent grounding wire during installation.

Before starting up, the operator should first familiarize themselves with the operating methods.

3. The instrument should not be used in gas environments with strong corrosive gases and particulate impurities.

4. The test environment temperature is between 15?C and 25?C, and the relative humidity is between 60% and 70%

5. Sparks are generated and accompanied by sound at the moment of sample breakdown, which is a normal phenomenon.

6. Each time the sample is replaced or the high-voltage electrode is in contact, a high-voltage discharge rod must be used to discharge the high-voltage electrode for at least 5 seconds.

7. Before each experiment, the instrument grounding must be checked.

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
