Suggestions for selection of transformer comprehensive test bench

The transformer comprehensive test bench is a specialized equipment used for electrical performance testing of power transformers. It integrates test wiring display, data acquisition, analysis and processing, measurement control, storage and printing, and protection functions. It can efficiently and accurately complete multiple core parameter tests and is widely used in the fields of power equipment manufacturing, testing, and substations. The selection of transformer comprehensive test bench should comprehensively consider various factors such as testing requirements, performance indicators, economy, and after-sales service. The following are specific suggestions:

1. Clearly define testing requirements

① Voltage level: Based on the voltage level of the tested transformer, select a test bench with an appropriate testing voltage range to ensure that the rated voltage on the high voltage side of the test bench is higher than the test voltage of the tested object.

② Current and Capacity: Based on the capacity and required current of the tested transformer, select a test bench with sufficient rated output current and capacity to avoid equipment overload or inaccurate testing.

③ Test items: Determine the required test items, such as no-load loss, load loss, transformation ratio, DC resistance, and insulation resistance, and select a test bench with corresponding testing functions.

2. Focus on core performance indicators

① Testing accuracy and stability: Choose a testing platform with high testing accuracy and good stability to ensure the accuracy and reliability of the test results. For example, the measurement accuracy of DC resistance should not be less than ± 0.2%, and the transformation ratio error should be ≤± 0.1%.

② Multifunctionality: Choose a test bench with multiple testing functions, such as the ability to simultaneously test parameters such as no-load current, no-load loss, impedance voltage, and load loss of transformers, to improve testing efficiency.

Data storage and report generation: Choose a test bench with large capacity data storage and automatic report generation capabilities for easy data management and analysis.

③ Anti interference capability: In complex electromagnetic environments on site, equipment must have good EMC design to ensure stable readings and accurate data.

3. Consider economy and cost-effectiveness

① Price: Choose a test bench that is reasonably priced and cost-effective, while meeting the testing requirements.

② Long term costs: In addition to equipment purchase costs, it is also necessary to consider equipment operating costs, maintenance costs, and upgrade costs. Choosing equipment with good durability and low maintenance costs can help reduce long-term costs.

4. Emphasize after-sales service and technical support

① After sales service: Choose suppliers who provide high-quality after-sales service, including technical support, software upgrades, and long-term maintenance services, to ensure that the testing bench receives timely and effective maintenance and support during use.

② User reputation and brand reputation: Review user evaluations and feedback on the test bench to understand its performance and issues in actual use. Choosing well-known brands and suppliers with good reputations can help reduce selection risks.

5. Reference actual cases and data

① Comparison of actual test data: Refer to the comparison of actual test data from different models of test benches to evaluate their performance in testing accuracy, testing efficiency, functional integration, and data management capabilities.

② Industry application cases: Understand the application cases of test benches in the fields of electricity, new energy, rail transit, etc., and evaluate their adaptability and reliability in practical applications.

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.
