(1) The instrument is an embedded industrial control computer, with a motherboard based on Cortex™-A8, a main frequency of 1GHz, and 1GB of flash memory, resulting in a fast boot time of only 16 seconds. It features a 9-inch color screen, Windows operating system, intuitive and user-friendly interface, and a touchscreen, supporting both Chinese and English input for easy use by on-site operators.
(2) High-speed thermal printer for convenient on-site printing of test data.
(3) Integrated power supply eliminates the need for a secondary power source on-site, making it convenient and quick to use. It provides an adjustable DC 6-270V power supply with a current of 20A. The operating voltage values of the opening and closing coils can be arbitrarily set, and low-voltage operation tests of circuit breakers can be performed.
(4) Equipped with linear sensors, rotary sensors, universal sensors, laser sensors (optional), brackets, and dedicated multi-functional connectors, making installation extremely convenient and simple.
(5) Applicable to all models of SF6 switches, GIS combined electrical appliances, vacuum switches, and oil switches produced domestically and internationally.
(6) All data and graphs are obtained with a single switch operation. Test data and graphs are displayed on the same screen, and the speed can be recalculated without further testing.
(7) The host can store 30,000 sets of test data (expandable with a memory card), and has a built-in real-time clock for easy archiving.
(8) Equipped with 2 USB interfaces, allowing for mouse operation and direct saving of data to a USB flash drive for analysis and storage on a computer. Optional: Data upload complies with the Q/GDW-12482.5-2024 State Grid communication protocol. Beidou positioning uploads latitude and longitude, and a temperature and humidity sensor measures the current climate in real time. Optional interfaces include RS232, RS482, or Bluetooth 5.0 for data upload, or communication with MES, ERP, and other platforms can be customized according to customer needs.
(9) Simultaneously measures 12 metal contact breaks, 6 main contacts and 6 auxiliary contacts, and 1 speed channel (3 speed channels optional).
(10) Includes envelope analysis. A standard envelope curve is generated from the values of a single switch test for analysis and comparison. Switch vibration frequency analysis is also available.
(11) The internal anti-interference circuit ensures reliable operation in 500KV substations.
Main Technical Parameters:
1. Time Measurement:
① 12-channel inherent opening (closing) time
② Opening (closing) time difference within a phase
③ Opening (closing) time difference between phases
④ Closing (opening) bounce time (number of bounces)
⑤ Asynchronicity test range: 0.1ms～99ms, resolution: 0.01ms;
⑥ Internal trigger test range: 0.1ms～999ms, resolution: 0.01ms,
⑦ 1000ms～9999ms, resolution: 0.1ms, 10000ms～200000ms resolution: 1ms.
⑧ External trigger test range: 0.01ms～200s
⑨ Accuracy within 1000ms: 0.05%±0.1ms
2. Speed Measurement: Initial opening (closing) speed, average speed over a specified time period (stroke segment or angle segment)
3. Speed Measurement Range:
① 0.1mm sensor: 0.01～20.00m/s, accuracy: ±0.1m/s
② 345° angle sensor: 0.01～20.00m/s, accuracy: ±0.1m/s
