TBP-100W1 Type for Outdoor Use at 10kV and Below

Modular Surge Arrester Summarize

With the vacuum switch the increasingly widespread use, its ability to trigger a strong breaking of the various types of operating voltage, the protection of electrical equipment on a new topic. Medium voltage power grid as a result of my (3-66kV) a number of particularities, conventional medium voltage surge arrester operation of such over-voltage is not sensitive to the protective effect would not serve any purpose. Combined over-voltage protectors (even Combined Arrester said) is to understand the decision of this problem and the emergence of new products.
The use of these products are four-star-type connection (Gu said Trident connection), set up a neutral point of the public, not only can significantly reduce the phase over-voltage, and the level of protection relative to the improvement of quality is also really played a switching operation of the vacuum effective restrictions on overvoltage.
The company's products for the composite insulation, compact structure, the overall sulfide forming closed. High-quality metal oxide and ceramic valves blowing special space, features the work of a high, safe and convenient. Particularly suitable and KYN, KGN, GBC, JYN, GZS, such as different types of medium voltage switchgear sets supporting the use of, or directly installed in the small box-type substation inside.

Usage Condition

The use of conventional political parties are as follows: 
★ ambient temperature: not higher than +40 ℃, not less than -40 ℃; 
★ Altitude: not exceed 2000m; 
★ Power frequency: 50 ± 2Hz; 60 ± 2Hz; 
★ earthquake intensity: 7 degrees and below; 
★ maximum wind speed: 35m / s; 
★-free clean-up conditions: dirty and below the middle region; 
★ seamless product of long-term frequency voltage imposed shall not exceed the continuous operating voltage protectors; 
★ gap on the products, the installation of point-frequency short-term increase in voltage should not exceed rated voltage protectors. 
    Long-term use in the following abnormal conditions require special protection, the order shall be given: 
★ excessive temperature or elevation (high altitude, tropical, boreal, all closed counters, and near the furnace, etc.); 
★ serious use of environmental moisture or impurities in corrosive gases (water, salt, chemical plants, etc.) 
★ strong ultraviolet radiation (high altitude, strong sunlight and other arid regions); 
★ special emphasis on dirty areas (mine face, working on construction sites, etc.).

Model & Meaning 

This product is no national standard definition of strict rules, the various manufacturers, according to its own testing center at the national application of the model, to define their own products, products of the enterprises use the same type vary widely. Models have not yet obtained certification of production enterprises, usually a reference JB/T8459-1996 "Arrester Model methodology," the overall expansion of the definition of provisions. My company's products for the national certification model TBP, the models are defined as follows:

At the same time I also Production GB/T8495-1996 "Arrester Model methodology," the establishment of the principle of expansion of the definition of conventional modular surge arrester products (some products less TBP), specific models are defined as follows:

Notes: 1, due to more use and voltage levels are not specified to operate 30/60 protectors pressure corresponding to the residual impact of the
impact of current value. 2, high-voltage products to be produced in the model that after the GY. 3, the vast majority of products matching counter,
