Electrical Component Comprehensive Test Bench |
Product Introduction
Suitable for factory testing and verification of main electrical performance of power transformers. Safe to use. The main test items are displayed on a color monitor with full Chinese prompts, enabling real-time monitoring of the entire test process.
Complete test items: 1. Transformer no-load characteristic test (no-load loss, no-load current percentage); 2. Transformer load characteristic test (load loss, impedance voltage percentage); 3. Transformer ratio, group, and ratio error test; 4. Transformer DC resistance test; 5. Transformer insulation resistance test; 6. Transformer power frequency withstand voltage test; 7. Transformer multiple frequency withstand voltage test; 8.
Ambient temperature test;
◆ The transformer test instrument integrates test wiring display, data acquisition, analysis and processing, measurement control, storage, printing, and protection. The entire test process is fully automatic, featuring high efficiency and high precision. ◆ The transformer test instrument has a backlit LCD display, simultaneously showing 18 parameters such as three-phase voltage and current; digital meters replace analog meters, and all test data is displayed in real-time (locked) on the screen, avoiding errors caused by parallax, conversion, calculation, and other factors during the test, ensuring higher accuracy. In particular, it completely solves the difficulty of operators reading multiple meters and recording multiple sets of data simultaneously, ensuring accurate and reliable test data. ◆ Data processing uses automatic storage and microcomputer printing, with beautiful, standardized data tables and clear handwriting. All test data is filled into corresponding tables in real-time, avoiding manual transcription and ensuring data authenticity and reliability. Users can also set print formats as needed. ◆ It is compact, lightweight, high-precision, and easy to test, making it an ideal product for power departments to upgrade.
The transformer comprehensive test instrument consists of three main parts: 1. Computer and data processing software system; 2. Data collection system for each test unit; 3. High-voltage control and instrument monitoring integrated system. Introduction to transformer comprehensive test instrument software: 1. Software installation conditions: works normally under Windows 98, Windows 2000, Windows XP, etc.; 2. Basic functions of the software: ① The transformer comprehensive test bench software can operate and control the transformer ratio tester, transformer winding DC resistance tester, and transformer characteristic tester; ② The software can query by test number, capacity, and test date; 3. Specific requirements for the software: ① The software human-machine
interface is friendly, and operation is intuitive and simple; ② The software can automatically receive transmitted data or manually input data. System configuration: (1) Transformer comprehensive test bench; (2) Voltage/current transformer control cabinet (optional); (3) Power control cabinet (optional); (4) System auxiliary cabinet (optional); (5) Transformer no-load and load characteristic tester (power analyzer); (6) Transformer DC resistance tester; (7) Transformer ratio and group tester; (8) High-voltage test transformer; (9) Medium-frequency generator set; (10) Induction voltage regulator; (11) Temperature patrol instrument; (12) Temperature sensor; (13) Partial discharge detection system (optional); (14) PLC controller; (15) Industrial computer and dedicated software; (16) Video monitoring system.
1. Read this manual carefully before using this instrument. 2. The operator should have general electrical knowledge. 3. Avoid places with rain, corrosive gases, excessive dust, high temperature, direct sunlight, etc. 4. Avoid severe vibration of the instrument. 5. After testing, wait until the discharge alarm stops before turning off the power and removing test leads. 6. When measuring no-load tap-changing transformers, wait until the discharge indication alarm stops before switching gears. 7. During testing, it is prohibited to move test clamps and power supply lines.
1. For no-load tap-changing windings, do not switch the no-load tap changer during testing or before discharge is complete. 2. For inductive test objects, do not remove test leads before discharge is complete (when the buzzer sounds), to avoid electric shock. 3. If external AC220V suddenly loses power during testing, the instrument will start automatic discharge. Do not remove test leads immediately; wait 5 minutes before removing them.
