Breakdown voltage testing machine
1, Scope of application and functions
Voltage breakdown tester - mainly suitable for testing the
breakdown strength and voltage resistance of solid insulation
materials (such as plastics, rubber, laminates, films, resins,
mica, ceramics, glass, insulation paints, and other insulation
materials and components) under power frequency voltage or DC
voltage.
2, System composition:
Control module: This instrument is controlled by computer upper
computer software and is a brand new third-generation dielectric
strength testing instrument independently developed by our company.
The core control system of this instrument is controlled by PLC,
and the data acquisition part is completed by digital integration
module. The communication with the computer and data acquisition
are completed by photoelectric isolation line, effectively solving
the anti-interference problem during the test process. Voltage
acquisition and current acquisition are completed by high-precision
sensors.
Voltage regulation module: This module is mainly used for voltage
regulation and can adjust the boost rate. It has high voltage zero
limit and high voltage boost limit. The main hardware components
include voltage regulators, motors, and other parts. The software
is easy to operate and can display the boost curve and leakage
current dynamic curve in real time. At the same time, the boost
rate is infinitely adjustable, and the boost rate can be adjusted
according to one's own needs, making the boost rate truly uniform
and accurate. After breakdown, it automatically stops, records test
results, displays test data, makes accurate judgments, and can
save, analyze, and print test data.
High voltage module: This module mainly uses a high voltage
generator to boost the voltage from low voltage at a set rate. The
core components mainly consist of transformers and matching
anti-interference accessories.
Test module: This section mainly consists of supporting test
electrodes, test oil tanks, and test brackets, which can be carried
out in a high-temperature testing environment according to user
needs.
