Renewable Design for Astm D877 Tester - High voltage switch comprehensive characteristic tester – Push

Core description

The high-voltage switch mechanical characteristic tester can accurately measure the mechanical dynamic characteristic parameters of high-voltage circuit breakers of various voltage levels, such as low oil, high oil, vacuum, and sulfur hexafluoride. High-voltage circuit breakers are responsible for the dual tasks of control and protection in the power system, and their performance is directly related to the safe operation of the power system. The mechanical characteristic parameter is one of the important parameters to judge the performance of the circuit breaker.

Parameter

Introduction

1. This instrument is an embedded industrial computer, the main board is based on CortexTM-A8, the main frequency is 1GHZ, the flash memory is 1GB, and the boot speed is only 16 seconds. Large 8.4-inch color screen, windows operating system, intuitive user-friendly operation interface, touch screen, support Chinese and English input, easy for on-site operators to use.
2. High-speed thermal printer, convenient for on-site printing of test data.
3. The integrated operating power supply in the machine eliminates the need for on-site secondary power supply, which is convenient and quick to use. It can provide DC5～270V adjustable power supply, current 20A. The operating voltage value of the opening and closing coil can be set arbitrarily, and the low voltage operation test of the circuit breaker can be done.
4. Equipped with linear sensor, rotation sensor, universal sensor and bracket, special fixed multifunctional joint, installation is extremely convenient and simple.
5. Suitable for all types of SF6 switches, GIS combination electrical appliances, vacuum switches, and oil switches produced at home and abroad.
6. The switch action once, get all the data and graphics.
7. The host can store 30000 groups of current test data (expandable memory card), and the real-time clock in the machine is convenient for archiving.
8. Equipped with U disk interface, can directly save the data to the U disk, upload to the computer for analysis and preservation.
9. It can measure 12 metal contact fractures, 6 main fractures and 6 auxiliary fractures at the same time.
10. Contains the envelope curve. The standard envelope curve is generated through the value tested by a switch for analysis and comparison, as well as the switch vibration frequency analysis.
11. The internal anti-interference circuit can satisfy the reliable use in 500KV substation.
