Introduction

The High-Voltage Circuit Breakers Analyzer is designed to meet the need of testing High-Voltage Circuit Breakers . It takes the ARM7 unit for core to sample, process and then output; the main characteristic is that it’s operated in alt. It has many advantages such as intelligence, multi-function, accurate data, strong anti-jamming, easy operation, small size, beautiful appearance, etc; It can test the Circuit Breakers as follows: indoors or outdoors Circuit Breakers with less oil or more oil, vacuum Circuit Breakers, SF6 Circuit Breakers and so on.

Features

1. Test standard: IEC62271
2. 12 channels metal contact breaks; 6 channels main contacts and auxliary contacts; 6

channels Closing Resistance simultaneously.
3. 8.4” imported high-brightness color large screen, clearly visible in the sun, embedded

operating system, windows operating interface, intuitive

interface, touch screen, easy for field operators to use.

4.High-speed thermal printer to facilitate on-site printing of test data.

5. Integrative operation power supply in the machine, without secondary power supply on site, is convenient and fast to use on site. DC20-265V adjustable power supply with 20A current can be provided. Arbitrarily adjust the operating voltage of the switching and closing coils, and can be used for low voltage operation test of circuit breakers.

6. Equipped with linear sensor, rotary sensor, sensor and bracket, special fixed

multi-functional connector, the installation is extremely convenient and simple.

8.4” color touch LCD.

7.Suitable for all types of SF6 switches, GIS combinations, vacuum switches and oil

switches produced at home and abroad.

8.Switch action once to get all data and graphics.

9.The host can store 6,000 groups of test data (extensible memory card), and the

real-time clock in the computer is easy to archive.

10.Equipped with U-disk interface, data can be directly saved to U-disk, uploaded to the

computer for analysis and preservation.

11.Included envelope, through the test data of several (2-10) switches, standard envelope can be generated, analyzed and compared, and switching vibration frequency can also be analyzed.

12.The internal anti-interference circuit can be used reliably in 800KV substation.
