Product Description

Three-phase combined overvoltage protector (three-phase combined surge arrester) is a protective appliance used to protect the insulation of power equipment from overvoltage hazards. It is a new type of surge arrester. , and effectively limit the phase-to-phase overvoltage , which is impossible for ordinary arresters. Widely used in the protection of vacuum switches, rotating electrical machines, parallel compensation capacitors, power plants, substations, etc. This combined protector has been operating for more than ten years, and practice has proved to be a feasible and effective measure to limit phase-to-phase overvoltage. The combined protector can play the role of six ordinary arresters. Since the protector uses large-capacity zinc oxide resistors as the main components, it has good volt-ampere characteristics and the ability to absorb overvoltage, and can provide reliable protection for the protection equipment, which is very popular in the power system.

Product implementation standards and use selection

This product implements the national standard GB11032-2000 "AC non-gap metal oxide arrester", JB/T10496-2005 "AC three-phase combined non-gap metal oxide arrester", ZBK49005-90 "AC system with series gap metal oxide arrester" ", JB/T8459-2006 "Surge Arrester Product Model Compilation Method".
The three-phase combined overvoltage protector is divided into a gapless type and a series gapped type. The difference in use is: for a gapless voltage protector, as long as there is an overvoltage on the system, it can be well absorbed and suppressed. With a gap type overvoltage protector, the gap type overvoltage protector will only act when the energy of the overvoltage on the system reaches the breakdown through the series gap type in the voltage protector and is used to discharge.
Therefore, it is recommended that users choose a gap-free voltage protector under normal circumstances, and a gap-type overvoltage protector is appropriate for places where the system disturbance voltage is too large or the switch is frequently opened and closed.
In order to facilitate the various use occasions of customers, our company has invested a lot of development efforts to develop a variety of combined overvoltage protectors and supporting instruments for users to choose.
If the cable needs to be lengthened, please specify when ordering. The outdoor type is not equipped with high-voltage cables. Please specify when ordering.
