I. Product Overview:



The high voltage switch machine characteristic tester, also known as a booster, is a basic test device for power stations, power supply and distribution systems, scientific research units, and other users. It is used to conduct insulation strength tests at specified voltages on various electrical products, electrical equipment, insulating materials, etc., to assess the insulation level of products, discover insulation defects in test objects, and measure their ability to withstand overvoltage.



II. Product Features:



1. Monitoring functions: output current   instrument voltage  zero position indication   open/close indication  timing indication



2. Protection functions: overcurrent protection   time relay



3. TQSB portable high voltage test transformer price adopts a new type of time relay, with a wider timing range.



4. Adopts a new type of current relay, which is more accurate and reliable, ensuring the safety of personnel and equipment.



5. Reasonable structure, small size, and light weight.



III. Technical Specifications:



1. Input voltage: 220V±10%   50HZ



2. Output voltage: 0-250V



3. Output capacity: 3KVA



4. Timing range: 1S-99H



5. Ambient temperature: -20oC to     50oC



IV. Usage Instructions:



1. Connect the wiring correctly and turn the voltage regulator counterclockwise back to zero. (Voltage cannot be increased if the regulator is not at zero.)



2. According to the test requirements, set the "time relay" and "current relay".



3. Plug in the power cord, the power indicator lights up, press the close button, and the power-on indicator lights up. (Voltage can now be increased.)



4. Rotate the voltage regulator handle clockwise at a uniform speed to the required value.



5. Start the timing switch, and when the "timing buzzer alarm" sounds, it indicates that the time has expired.



6. Turn the voltage regulator counterclockwise to zero, press the open button, and the power-on indicator goes out.



7. Unplug the power cord and remove the wiring, the power indicator goes out, and the test ends.



V. Precautions:



1. During use, the instrument should be reliably grounded.



2. The voltage increase and decrease process should be uniform, not too fast or too slow.



3. During the test, the monitoring instruments should be observed at all times to detect unexpected situations promptly.
