I. Product Overview:



The High Voltage Switch Machine Characteristic Tester, also known as a booster, is a basic test equipment for power stations, power supply and distribution systems, scientific research units, and other vast users. It is used to conduct insulation strength tests under specified voltages on various electrical products, electrical equipment, insulating materials, etc., to assess the insulation level of products, discover insulation defects in the tested object, and measure the 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 correctly, turn the voltage regulator counterclockwise back to zero. (Voltage cannot be increased if the regulator is not at zero)



2. According to 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. (At this point, voltage can 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 is up.



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



7. Unplug the power cord and remove the wiring, the power indicator goes off, and the test is completed.



V. Precautions:



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



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



3. During the test, monitor the instruments at all times to promptly detect any unexpected situations.
