Product Description

Vacuum Switch Vacuum Tester VCM-IV

The usual method for vacuum circuit breaker users to judge whether the vacuum degree of the vacuum tube is degraded is the power frequency withstand voltage method. This method is only an arc extinguishing chamber that can judge the degree of vacuum deterioration. When the vacuum degree deteriorates to 10-2--10-1Pa, although the breakdown voltage does not decrease, the arc extinguishing chamber is no longer qualified. The HYKZ-IV vacuum tester adopts the magnetron discharge method of the new excitation coil to test the vacuum of the arc extinguishing chamber without dismantling the arc extinguishing chamber. At the same time, the computer is used for synchronous control and data acquisition and processing, so that the on-site test sensitivity of the vacuum degree of the interrupter reaches 10-4-10-1Pa. The most prominent feature of this instrument is the use of a new type of excitation coil and data processing method to achieve a non-removable measurement of the vacuum degree. This instrument has the advantages of convenient use, simple operation, non-disassembly measurement and high accuracy. It is a practical testing instrument, which is widely used in electric power, steel, petrochemical, textile, coal, railway and other departments that use real switches. Pull the two contacts of the arc extinguishing chamber apart-a fixed distance, and apply pulse high voltage: place the arc extinguishing chamber in the screw tube coil or place the new electromagnetic coil outside the arc extinguishing chamber, and apply a magnetic field voltage to the coil, thereby extinguishing A pulsed magnetic field synchronized with the high voltage is generated in the arc chamber. In this way, under the action of a strong pulsed magnetic field and a strong electric field, the electrons in the arc extinguishing chamber move in a spiral motion and collide with the residual gas molecules. The generated ion power is approximately proportional to the residual gas density (ie, the degree of vacuum). . For different types of vacuum tubes (tube type), due to their different structures, the size of the ion power supply is different under the same contact distance, the same vacuum degree, and the same electric field and magnetic field. Through experiments, the corresponding relationship curve between the vacuum degree of various tube types and the ion power supply can be calibrated. After the ion current is measured, the vacuum of the tube can be obtained by querying the ion current-vacuum curve of the tube.
