Product Description

 

Product Features

1. Suitable for testing products of SF6 switch, GIS combination electrical appliances, vacuum switch, oil switch, vacuum contactor, special circuit breaker (train circuit breaker). At the same time, 12 metal contact fractures, 6 main fractures and 6 auxiliary fractures can be measured. When the circuit breaker is operated for one time, the data and waveform, such as time, bounce number and time, speed, coil current and coil resistance, are obtained. The analyzer include energy storage, automatic and manual low jump test, circuit breaker life test and lock power supply and dry contact control (optional function for the bold part). Equipped with high speed thermal printer, convenient to print test data on site.
2. 7 inch color screen, clearly visible even when operating under the sun. Menu operation, quick test interface, one-key operation. The 12-channel fracture status is displayed in English. The time, stroke, speed and waveform are displayed on the same screen. Analyze the average velocity of the specified segment and mark it on the stroke curve for easy viewing.
3. Integrated with operation power supply, no need secondary power on site, easy to use. Can provide DC20 ~ 270V adjustable power supply, current 20A. Short circuit protection function. In case of short circuit, 1ms will stop the voltage and current output and emit a beep to prompt the operator to check the circuit. Unique double circuit power supply design, if one of closing or breaking control circuit is damaged, the other can also support for the testing.
4. Equipped with linear sensor, 360 degrees without dead Angle rotation sensor, with special fixed multifunctional joint, installation is very convenient, simple. The length of the 30-1000mm linear sensor can be set arbitrarily.
5. the host can store 100 groups of test data, real-time clock in the machine, easy to archive.
6. Equipped with U disk interface or R232 interface, data saved to U disk, uploaded to the computer for analysis, saving, printing. R232 interface can be connected to the computer online operation (optional function).

       7. The internal anti-interference circuit can be used reliably in 500KV substation.
