1Beijing Huace High Voltage Polarization Test DeviceProduct Introduction：
Dielectric polarization refers to the phenomenon in which a dielectric exhibits electrical properties under the influence of an external electric field. There is no free charge inside the ideal insulating medium, but there is always a small amount of free charge inside the actual dielectric, which is the cause of dielectric leakage. In general, the positive and negative bound charges inside the dielectric without the action of an electric field cancel each other out on average, and do not exhibit electrical properties macroscopically. Under the action of an external electric field, the local movement of bound charges leads to macroscopic electrical properties, resulting in the appearance of charges on the surface and uneven areas inside the dielectric. This phenomenon is called polarization, and the resulting charges are called polarized charges.
The HCJH-10KV high-voltage polarization device can achieve simultaneous polarization of multiple samples and generate polarization curves for different samples and voltages. It can quickly determine the optimal polarization electric field, temperature, and time, with better performance and more convenient operation.

4Beijing Huace High Voltage Polarization Test DeviceProduct Features：
Intelligent monitoring, software displays the curve of current changes, and can observe the polarization process in real time;
Synchronized display of voltage, time, and temperature for visualization;
● Touch screen design, easy to operate and reliable;
6 channels are polarized simultaneously, each with detection, protection, cut-off functions, and light indication;
When the leakage current of each circuit exceeds the specified value, it does not affect other circuits and can still complete polarization according to the normal polarization time;
Heating and constant temperature, the heating speed can be adjusted, and the constant temperature time can also be freely set;
Electromagnetic stirring device, making heating more uniform;
Adopting PID control for silicone oil heating, with clear temperature control and more standardized collection;
5Beijing Huace High Voltage Polarization Test DeviceMain advantage：
TVS instantaneous suppression protection technology: Optocouplers and isolation are nothing more than anti-interference processing to improve the acquisition of instruments, and have no effect on protecting the control system from surges during flashover discharge processes. The TVS instant suppression protection technology independently developed by Huace will provide security protection for the control system.
Multi level cycle temperature acquisition technology: The equipment adopts PID algorithm and multi-level cycle temperature acquisition to ensure the effective value of temperature. The temperature control and measurement use the same sensor to ensure that the temperature collected each time is the actual temperature of the sample
● Dual system interlock technology and isolation shielding technology: This device not only has overvoltage and overcurrent protection systems, but also its unique dual system interlock mechanism. When any component has a problem or a single system fails, the power will be instantly cut off. Adopting low-pass filtering current detection technology to ensure the effective value of the collected current and the shielding of current anti-interference.
Currently, most imported equipment adopts SPWM electronic boost technology, which has stable boost speed and high accuracy.
The testing voltage can reach 12000V. Currently, the resistivity testing instrument has a testing voltage of 12000V. It can meet the polarization requirements of materials at home and abroad, and is also the testing equipment with the largest number of testing channels.
