high voltage switchgear circuit breaker test set
Features
- It is suitable for the mechanical test of all types of SF6 switches, GIS combination appliances, vacuum switches, and oil switches.
- Strong anti-interference ability. It can be easily tested and accurately measured in 500KV substation.
- Accelerometer (optional), linear sensor, rotary sensor, easy to install and simple.
- When the switch is actuated once, all the data of the switch mechanical characteristic test and the corresponding waveform map are obtained.
- Store the field test data and built-in real time clock, which is convenient for archiving and saving the test date and time.
- With 8inch LCD screen, display all data and map, with background light, LCD contrast adjustment and power off memory.
- Friendly menu operation, easy to use. With built-in printer to quickly print all data results.
- Equipped with data analysis management software, which can be operated online with PC, with WORD format file. The test results can be output to all kinds of printers printing test reports to make the field test computerized.
- Combined speed selection and user-defined function set according to needs, suitable for the speed measurement of any type of switches.

Operating pressure: DC30~250V/20A of digital regulated operating power supply of circuit breaker is supplied in the device, and test of low-pressure operating is completed automatically to measure the operating voltage of circuit breaker.
2. Characteristics
It is applicable to all the types of SF6 switch, GIS switchgear, vacuum switch and oil switch with metal contact manufactured at home and abroad.
With universal speed sensor, linear travel sensor and rotation sensor, it is very convenient and simple to install it.
The main frame has a liquid crystal large screen, of directly transmissive type, with background light, and the contrast is adjusted electronically. Menus in Chinese gives prompt for operation. If you carry out on-off action once, then it will display all the data and oscillogram.
The main frame can store several sets of switch off and switch on test results, and there is a real-time clock in the device so that it is convenient to file and record the date and specific time of test.
Built-in micro-printer of fast speed can print out all the data and illustrations.
The instrument is equipped with the software Circuit Breaker Data Analysis Management Software connected with a PC, and test results can be either saved in the hard disk directly or sent to all kinds of printers so that test reports can be printed out. This makes field tests computerize.
The instrument is provided with strong data analysis function, which is able to effectively analyze each index and parameter of mechanical characteristics of circuit breakers.
The instrument is equipped with user-defined additional program of speed so that users can free add all kinds of instantaneous opening speed and instantaneous closing speed as necessary.
