The transformer comprehensive characteristic testing platform, as the core equipment for power transformer detection, can be summarized into four dimensions: high precision, high integration, high safety, and intelligence. The specific technical characteristics are as follows:
1. Full parameter synchronous detection, achieving industry benchmark accuracy
① Multi parameter real-time display
Adopting LCD backlit display screen, it can synchronously display 18-20 key parameters such as three-phase voltage, current, power, power factor, etc. The data lock display function completely eliminates manual reading parallax, avoids multi meter synchronous recording errors, and improves the testing accuracy to level 0.2, meeting the requirements of national standards such as GB/T4776 and GB/T5169.
② Accurate measurement of low power factor
Integrated frequency conversion power sensor and fiber optic transmission technology can accurately measure power parameters within the power factor range of 0.1-0.9999, suitable for precise analysis of low-power scenarios such as no-load loss and load loss.
2. Full process automation integration, doubling operational efficiency
① Full coverage of experimental projects
Integrated with 8 core functions including no-load test, load test, short-circuit impedance measurement, DC resistance test, transformation ratio group test, insulation resistance test, power frequency withstand voltage test, and frequency doubling induction withstand voltage test, it supports full project testing of transformers below 2500kVA without the need for multiple equipment switching.
② Intelligent Control and Data Processing
a. One click operation: Multi screen menu driven, automatically completes the entire process of test wiring display, data acquisition, analysis and processing, storage and printing.
b. Automatic correction function: built-in waveform distortion correction, test wire resistance correction, transformer error correction, eliminating environmental interference and system errors.
c. Database management: The Access database is used to store raw data and automatically generate equipment files containing equipment parameters, test data, environmental temperature, and test dates. It supports quick queries based on test numbers, capacities, dates, and other conditions.
3. Multiple security measures to ensure personal and equipment safety
① Electrical safety design
a. Overvoltage/overcurrent protection: Real time monitoring of voltage and current, triggering sound and light alarms when exceeding limits and automatically cutting off power supply.
b. Line connection error protection: automatically identifies wiring errors to prevent equipment damage caused by misoperation.
c. Discharge alarm system: After the withstand voltage test, a continuous buzzing alarm will sound until the discharge is completed before removing the test line to avoid the risk of electric shock.
② Environmental adaptability optimization
a. Wide temperature working range: Supports extreme environmental temperatures ranging from -10 ℃ to 50 ℃, with a humidity adaptation range of 0-90% RH.
b. Anti interference capability: The digital design of the sensor front-end combined with fiber optic transmission effectively shields electromagnetic interference and ensures data stability.
4. Modular and portable design, suitable for diverse scenarios
① Flexible customization of form
Provide various forms such as desktop, portable, simplified, and standard according to usage scenarios, to meet the needs of different scenarios such as substations, power plants, and transformer manufacturing enterprises.
② Rich extension interfaces
Supports external voltage/current transformers, with a current measurement range extended to 0.1mA-200A and a voltage range of 0.1-600V.
Reserved communication interface, adaptable to remote monitoring and data analysis systems, to achieve real-time tracking of equipment status.
5. Typical application scenarios
① Factory inspection: Quickly complete the verification of key parameters such as transformer no-load loss, load loss, and transformation ratio to ensure product qualification rate.
② Regular maintenance: Through DC resistance testing, insulation resistance testing, and other projects, potential hazards such as poor contact and insulation aging can be detected in advance.
③ Fault diagnosis: Combined with the harmonic analysis module (detecting 31st harmonic), locate the abnormal parameters of the internal inductance and capacitance of the transformer, and provide data support for maintenance.
Summary: Thetransformer comprehensive characteristic testing platform has significantly improved the efficiency and accuracy of transformer testing through four core advantages: full parameter synchronous detection, full process automation, multiple safety protections, and modular design. It has become an essential tool for equipment maintenance and quality control in the power industry. Its technical parameters and functional design have reached the international advanced level, providing a solid guarantee for the safe operation of transformers.
ZC-200 transformer comprehensive test bench is mainly used to test the no-load and load characteristics of power transformers and distribution transformers, and can also perform frequency doubling induction and power frequency withstand voltage tests on the tested transformers. The measuring part of the device is controlled by a high-end microcontroller, and the digital display, no-load, short circuit and other test data are synchronously sampled by the microcontroller, avoiding the errors caused by manual calculation of voltage, ammeter and power meter readings in traditional testing methods. This equipment is suitable for factory and routine testing of three-phase transformers with a capacity of 5000kVA/36.2-13.2KV and below in the production and maintenance departments of power transformers.
