Product Description

Main uses and functions

The product is mainly suitable for testing the breakdown strength and withstand voltage time of solid insulation materials such as plastic, film, resin, mica, ceramics, glass, insulation paint, etc. under power frequency voltage or DC voltage; This instrument adopts computer control and can quickly and accurately collect and process various data during the experimental process, as well as access, display, and print.

This instrument has radiation protection function. The test door of the instrument is made of transparent insulated glass with a shielding mesh sandwiched between it. During the test, a large current will be generated at the moment of breakdown, which poses a radiation hazard to human health. Our company has conducted shielding treatment on this instrument to reduce the risk to human health.

This instrument also has lighting function, as there will be dim light during the experiment, which can be applied to make the user's observation more obvious and achieve better experimental results.

Equipment composition principle and safety protection
1	The equipment mainly consists of high-voltage test transformers, contact type voltage regulators, servo speed control systems,acquisition systems, control systems, automatic discharge, and other parts.
2	The input of the test transformer is provided by the output of the voltage regulator, and the high-voltage output is collected in real-time by the acquisition system. The computer adjusts the speed control system that controls the rotation of the voltage regulator based on the voltage, forming a closed loop to make the voltage regulation process smoother. And it can meet the requirements of slower speed boosting.
3	Automatically distinguish between AC and DC test processes. If after the DC test, the discharge operation can be automatically carried out after the test is completed. During this period (when the test chamber door is not discharged), there will be an audible and visual alarm to warn of danger!
