TBP-40 overvoltage protector tester Introduction: The TBP-40 overvoltage protector tester is widely used for testing the power frequency discharge voltage of various electrical equipment, especially for testing the power frequency discharge voltage of zinc oxide overvoltage protectors with gaps (also known as lightning arresters or TBPs), which has a unique effect. The tester adopts a new type of special circuit to monitor the test voltage waveform, collect discharge pulse signals from the current circuit, automatically judge the gap discharge, lock the voltage peak at the moment of discharge, and emit an audible alarm signal to remind the tester, and quickly cut off the test power supply to protect the test object and test equipment from overcurrent damage. The tester integrates a power frequency high-voltage power supply, measurement, and control system, concentrated in an aluminum alloy box. It is small in size, light in weight, shockproof and resistant to falling, easy to operate, and convenient to carry. Features: 1. The instrument adopts waveform detection and Fourier transform methods to constantly monitor the discharge current. When the discharge current is detected, immediately record the current high voltage and cut off the high voltage power supply within 0.2 seconds. The test results have high accuracy and are easy to achieve automated measurement. 2. The instrument adopts a large screen LCD display, and the testing process is prompted through a Chinese menu, which is both intuitive and easy to operate. 3. The instrument is easy to operate, and data measurement is automatically completed under the control of a microprocessor. No need for manual intervention 5. Integrated model with built-in high-voltage power supply for easy on-site testing and reduced wiring. 6. High voltage protection: The test object can be short circuited, broken down, or the high voltage current fluctuates, and the output can be cut off at high speed through short circuiting. 7. Low voltage protection: Misconnection of 380V, power fluctuation or sudden power outage, starting the protection will not cause overvoltage. 8. Anti misoperation: two-stage power switch; Real time monitoring of voltage and current; High/low voltage clear wiring terminals; Slow pressure increase, can quickly reduce pressure, and sound an alarm. 9. Seismic performance: The instrument adopts a unique seismic design, which can withstand strong long-distance transportation vibrations and bumps without damage. 10. High voltage cable: It is a high-voltage resistant insulated wire and can be used for dragging the ground. Technical parameters: Output voltage 0-30kV, output current 0-25mA Detection discharge method: waveform detection and Fourier transform method Accuracy: Voltage: ± (reading × 2%+0.1) Current: ± (reading × 2%+0.1) High voltage cutoff time: less than 0.2 seconds Input power supply: 180V~270VAC, 50Hz/60Hz ± 1%, mains or generator power supply Computer interface: standard RS232 interface Printer: Weihuang A7 thermal micro printer Environmental temperature: -10 ℃~50 ℃ Relative humidity:<90%
