Product Description
The SXBZ Series Transformer Test Bench is a professional all-in-one high voltage testing equipment, specially designed for full-range factory inspection and routine maintenance testing of various power transformers.
It is widely applicable to power grid supply & distribution stations, transformer manufacturing factories, transformer maintenance service centers and related electrical testing labs. The whole unit supports personalized customization according to customers’ actual testing demands, and can be configured as bench type or microcomputer integrated type to adapt to different test sites.
This test bench integrates all core transformer testing functions, covering no-load & load loss test, winding resistance, turn ratio, impedance, power frequency withstand voltage, induced overvoltage, partial discharge, temperature rise, impulse voltage, insulation test and transformer oil analysis. Equipped with PLC control system and high-precision A/D converter, it realizes automatic data acquisition, calculation, storage, printing and test report generation, greatly improving testing efficiency and test data accuracy.
Complete multi-layer safety protection mechanisms such as overvoltage, overcurrent, overload, misoperation and wrong wiring protection are built in to guarantee safe operation for operators.
Product Features
- Dual operation modes with interlock protection: push-button manual control and computer automatic control; only one mode can run at the same time to avoid misoperation.
- Full English operation interface, convenient for overseas users to operate and debug.
- Large LCD display screen, real-time synchronous display of 18 testing parameters including three-phase voltage, current and other core indicators.
- Adopts industrial high-speed processor + PLC controller, matched with high-precision A/D converter; all test data is automatically calculated, stored, printed and exported into customized test reports.
- Flexible equipment structure customization: optional desktop bench type or microcomputer integrated type to fit different laboratory space.
- Automatically switch PT & CT measuring ranges with adjustable voltage and current ratio; direct display of final test values without manual conversion.
- Built-in ACCESS database, which can store test parameters, real-time data, ambient temperature, test date and other information, support data query, browsing and analysis.
- Supports accurate measurement under low power factor conditions (power factor range: 0.01–1.00).
- Comprehensive multi-protection system: overload alarm, wrong wiring protection, misoperation protection, overvoltage & overcurrent protection.
- Complete automatic control modules: external induction voltage regulator, single-phase voltage regulator, voltage/current transformer switching control, with real-time voltage & current monitoring and overcurrent interlock protection.
