The combined overvoltage protector product is specially used in 35KV and below medium-voltage networks; it can not only protect against over-voltage cut-off, over-re-ignition over-voltage and three-phase simultaneous over-voltage over-current, but also protect lightning over-voltage; therefore, it has a Series of other types of overvoltage protectors can not compare advantages.
The overall function of the TBP overvoltage protector has achieved a major breakthrough, and is currently the most comprehensive and most complete product with the most comprehensive protection. It conforms to the national industrial policy and the development trend of national electrical products such as oil-free, miniaturization, energy saving and environmental protection, and has significant technical and economic benefits and a wide range of social benefits.
The main features are:
1, over-voltage protection can completely inhibit the harm of lightning and operating over-voltage, powerful, more comprehensive protection;
2, dual circuit design, complementary functions, mutual protection;
3, reduce the steepness and eliminate the risk of breakdown during the day;
4, automatic access, environmental protection and energy conservation;
5, free from harmonic interference, adapt to the wider operating environment of the power grid;
6. Self-control disengagement, effective control of accident coverage.
Phase combined overvoltage protection device is a new overvoltage protection for limiting atmospheric over operation due to over voltage and various vacuum switches. While protecting the over-voltage between phases, it also provides protection against phase-to-phase over-voltage. With excellent atmospheric over-voltage and over-voltage protection performance, it can effectively protect system inter-phase over-voltage in addition to protection system over-voltage. It is an ideal replacement product for common arresters. The three-phase combined overvoltage protector features compact structure, beautiful appearance, convenient installation and superior performance. To sum up, there are the following points: 1. Select a high-capacity, high-quality zinc oxide valve to ensure performance and operating life. 2. The internal use of a new symmetrical composite structure, stable discharge, outstanding pressure limiting performance. 3, according to the need for pressure equalization gap ring, with excellent over-voltage protection level and safety performance. 4. Combined overvoltage protector can effectively prevent intermittent arc grounding with impact energy less than 2mS/400A.
