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 under specified voltages on various electrical products, electrical equipment, insulating materials, etc., to assess the insulation level of products, discover insulation defects in the test 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 Method:

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 light will be on, press the close button, and the power supply indicator light will be on. (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 supply indicator light will go off.

7. Unplug the power cord and remove the wiring, the power indicator light will go off, and the test is completed.

V. Precautions:

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

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

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