Main Features:
1. Vacuum arc extinguish; solid insulation; no oil and SF6; no environment pollution; impossible explosion and gas leak; comply with environment protection requirement
2. Fully sealed waterproof design; no exposure of high-voltage conductor; especially suitable for wet and areas with frequent flood. It is able to supply power under wet and soaking situation.
3. For rhe operation mechanism, the user can select permanent magnet mechanism or spring operation mechanism according to user's habit and actual needs.
4. Integral design of isolation, grounding switch and circuit breaker; compact structure, and complete reliable mechanical and electric locking structure design. It can prevent wrong operation effectively.
5. Adopt fast algorithm with national patent technology (patent number:ZL200720037710.7) so as to obtain fast breaking capacity of circuit breaker. As a result, it can isolate fault circuit rapidly. Taking the example of 10kV circuit breaker, it needs less than 25ms from inspecting fault to cut fault circuit by separate circuit breaker. It can avoid the problem of override trip effectively.
6. Adopt single phase ground protection system with national patent technology (patent number:ZL201020178325.6). It can realize on-line judgement on the single phase ground fault of small current ground system without adding devices. In the meanwhile, it realeases warning or tripping action according to setting value.
7. Apply the most advanced insert operation system nowadays; adopt double CPU structure, including ARM9 with general processing and system control; and strong DSP with high efficiency processing on multi-missions; and realize high speed data processing, control and communication.
8. It is equipped with complete electricity displayer and reliable switch position indicator.
9. Building block design, it is able for extension by needs.
10. Compact structure, small volume, light weight, convenient installation.
11. Visible isolation fracture, comply with safety standard.
12. Identify power supply mode automatically; realize automatic double power cutting flexibly; improve power supply reliability.
13. Flexible communication ways; support GSM short message, GPRS,CDMA general wireless business, optical fiber, twisted-pair, wireless, carrier wave and other communication ways; and support various kinds of communication agreement.
14. Adopt temperature measurement and modification technology so as to make the switch device operate reliably and stably under different environment conditions across the country.
15. AVR series measuring cabinet adopts different Bus extension method. It enriches the Bus extension type of solid insulated ring network cabinet. It has compact structure. The build-in voltage transformer and current transformer for measurement can be equipped with gauging table, load management terminal or reserved installation location by needs.
