I Introduction

Switching characteristic tester Is a special instrument developed by our company to meet the requirements of Various HV switch action characteristics testing, which can accurately measure the mechanical dynamic characteristic parameters of low oil, high oil, vacuum, Sulfur hexafluoride and other HV circuit breakers of various voltage grades. for circuit breakers with closing resistance, the closing resistance and Switching waveform can be measured accurately. The instrument adopts large Screen display, Chinese characters prompt man-machine dialogue operation, English characters display results and print output, with  the advantages of intelligence, many Functions, accurate data, strong anti-interference, simple operation, small size, Light weight, nice  appearance and so on.

II Performance

1.       It is applicable  for all Types of SF6 switch, GIS composite apparatus  , vacuum switch,  mechanical Characteristic test of oil switch at home and abroad.

2.       Super strong anti-interference ability, It also can easily test in the case of a  500 KV transformer Substation interbus charged, precision measurement.

3.       Acceleration sensor (optional), linear sensor, rotation sensor, Installation is convenient and simple.

4.       Switch act once, it can get all the data and the corresponding Waveform grap of switch mechanical characteristic test

5.       the host can storage  field Test data and built-in real-time clock, to archive preservation test date and Time.

6.       Host is equipped with large screen, wide temperature, straight Perspective, background light LCD, full English display all data and graph, LCD contrast electronic control, outage memory.

7.       English menu operation, easy to use. the instrument has a built-in Printer to quickly print all data and graphs at any time.

8.       the deviceis  equipped with a Large touch screen data analysis software, which can be connect with PC Operation online, the test results can be output to the various kinds of needle Type, laser or inkjet printer to print test reports, make field test Computerized.

9.       Just speed selection and a custom function, according to Requirement to set, any analysis, applies to any type switch speed of  any switch factory company  at home and abroad

Feature

1. Time: 12 contacts' fixed opening time and closing Time, in-phase same time, out-phase same time.

2. Reclose: close-open, open-close, open-close-open for each breaker; process time: 1 opening time, 1 closing time, 2 closing time, Metal short circuit time, no-current time.

3. Springing: closing springing time, springing Numbers, spring  process, springing Waveform for each breaker; rebounded amplitude for each breaker.

4. Speed: instant opening, closing speed, max speed, Time-range characteristic curve.

5. Range: total range, open range, over-range, Overriding range, rebound magnitude.

6.Current: opening/closing current of opening/closing Coil, current waveform diagram.
