WDGK-12FCircuit breaker characteristic testerInstrument features:

⑴. This instrument is an embedded industrial computer with a Cortex-TM-A8 motherboard, a main frequency of 1GHz, 1GB of flash memory, and a fast startup speed of only 16 seconds. 9-inch color large screen, Windows operating system, user-friendly interface, touch screen, supports Chinese and English input, easy for on-site operators to use.

⑵ High speed thermal printer, convenient for on-site printing of test data.

⑶ Integrated operation power supply inside the machine, no need for on-site secondary power supply, easy and fast to use. It can provide adjustable power supply ranging from DC6 to 270V, with a current of 20A. The operating voltage values of the opening and closing coils can be set arbitrarily, and it can also be used for low-voltage operation tests of circuit breakers.

⑷ Equipped with linear sensors, rotation sensors, universal sensors, laser sensors (optional), as well as brackets and dedicated fixed multifunctional joints, the installation is extremely convenient and simple.

⑸ Suitable for all models of SF6 switches, GIS composite appliances, vacuum switches, and oil switches produced domestically and internationally.

Once the switch is activated, all data and graphics are obtained, and the test data and graphics are displayed on the same screen. The speed can be recalculated without the need for further testing.

⑺ The host can store 30000 sets of current test data (expandable storage card), with a real-time clock inside for easy archiving.

Equipped with 2 USB interfaces, the instrument can be operated with a mouse, and data can be directly saved to a USB drive and uploaded to a computer for analysis and storage. RS232 interface online operation (optional), WIFI operation optional.

At the same time, it can measure 12 metal contact fracture surfaces, 6 main fracture surfaces, 6 auxiliary fracture surfaces, and 1 speed (3 speed options available).

(10) It contains an envelope line, which generates a standard envelope line based on the values tested by a switch for analysis and comparison. It can also perform switch vibration frequency analysis.

11. The internal anti-interference circuit can meet the reliable use in a 500KV substation.
