Product Description
High voltage circuit breaker is one of the most important control equipment in the power system. GDKC-15A is used to test the dynamic characteristics of high voltage circuit breaker. It is easy to operate, with high accuracy.
Features
- Embedded industrial control computer. The main board is based on the CortexTM-A8, the main frequency is 1GHz and the flash memory is 1GB. The booting speed is only 16 seconds. 8.4-inch color screen, windows operating system, intuitive user-friendly interface, touch screen, support for Chinese and English input, easy to operate.
- High-speed thermal printers facilitate field printing of test data.
- Internal integrated power supply, no need for on-site secondary power supply, easy to use. Can provide DC10 ~ 260V adjustable power supply, current is 20A. Arbitrarily set the action voltage of the opening and closing coils, and can be used for low-voltage action test of circuit breaker.
- Equipped with a linear sensor, a rotation sensor, a universal sensor and a bracket, and a special fixed multifunctional joint, the installation is extremely convenient and simple.
- Applicable to all models of domestic and foreign production of SF6 switches, GIS combination appliances, vacuum switches, oil switches.
- Switch action once, get all the data and graphics
- The host can store 30000 sets of field test data (extensible memory card), real-time clock inside the machine, easy to archive.
- Equipped with U disk interface, can directly save the data to U disk, upload it to the computer for analysis and save.
- Able to measure 12 metal contact and 3(6) double-end grounded switch at the same time.
- Including enveloping line, through the numeric value of multi switch test (2-10) to generate standard enveloping line, carry out analysis and comparison, the analysis of switch vibration frequency can also be carried out.
- Internal anti-interference circuit can meet the reliable use of 800KV substation.
