Product Name:Phase combined over-voltage protection【Phase combined over-voltage protection】
■Outline
Phase combined over-voltage protection (three-phase modular surge arresters) are used to protect electrical equipment insulation against over-voltage protection of electrical hazards, is a new type of lightning arrester, which limit overvoltage between phases simultaneously, and to phase overvoltage effectively limited, widely used to protect the vacuum switch, rotary motor, parallel compensation capacitor, power plants, substations, etc. this combined arrester has been in operation for over ten years, proven to be a practical and effective restrictions phases over-voltage, a modular surge arrester can play the role of six ordinary arrester. Since the use of a large-capacity internal arrester zinc oxide varistor as the main component, it has a good over-voltage characteristics and the absorption capacity of voltage protection devices can provide reliable protection, it has been widely used in the power system.
■Implementation of standards
This product implementation GB GB11032-2000 《metal oxide surge arresters without gaps for AC》, JB / T10496-2005 《AC three-phase modular metal oxide surge arresters without gaps》, JB / T10609-2006 《AC three-phase modular series gap MOA 》, JB / T8459-1996《 arrester Model methodology. 》
■Structural features
1. Compact form factor, insulation resistance, high pressure, which greatly reduced the use of space utilization and;
2. Integrally molded composite jacket, has a good seal, explosion-proof, moisture resistant, anti-leakage trace, anti-electric corrosion, stain resistance, water repellency is good;
3. Novel and unique structure, excellent technical performance, good electrical insulation properties;
4. High voltage cable, ensure that the insulation strength, flexible installation;
5. Small size, light weight, saving land, especially for installation in the control cabinet.
■Conditions of use
1. Altitude of not more than 2000m (when ordering more than 2000m told);
2. Ambient temperature: -40 ℃ ~ + 40 ℃;
3. Power frequency: 48Hz ~ 62Hz;
The long-term frequency voltage applied to the arrester does not exceed the continuous operating voltage of the arrester;
5. Maximum wind speed does not exceed 35m / s;
6. seismic intensity of 7 degrees and the following areas.
■Phase combined over-voltage protection Select
Phase combined over-voltage protection is divided into non-gap and with series gap, the difference between the use of: for non-gap over-voltage protection, as long as there is over-voltage on the system, can be well absorbed and suppression ; and a gap-type over-voltage protection, over-voltage on the system only energy reaches the breakdown voltage protection device and discharging it in the series gap, the gap-type over-voltage protection will be action.
It is recommended that users in the selection: the conventional case select no gap over-voltage protection, system rope fixed voltage is too large or frequent switching division and site selection have gap-type over-voltage protection is appropriate.
In order to facilitate customers' various applications, the company has invested a large development efforts, developed a variety of combined over-voltage protection and ancillary equipment for users to choose.
 
3 ~ 35kV gapless type (indoor type, outdoor type)
Three-column (B type), four-post (A-type)
3 ~ 35kV gap type (indoor type, outdoor type) Three-pillar (B type), four-post (A-type)
Standard cable length: 6 ~ 10kV: phase element to element 500mm 400mm
35kV: phase element to element 600mm 550mm
* Cable extension when ordering
* Outdoor unworthy of high-voltage cables For when ordering.
With phenotype (characteristic model suffix letter "B")
3 ~ 35kV indoor type voltage protectors and comes with modular overvoltage monitoring panel installation while displaying the year, month, day, hour, minute, and each phase the number of operations, 30 sets of data stored in a computer chip. (Part number suffix special sheet letter "BJ") 3 ~ 35kV outdoor type voltage protection and over-voltage line monitor incidental or discharge counter (model suffix letter special film "BJ" or "BF")
Explosion-proof type (model features the letter suffix "KY") Energy Capacity Type
Explosion-proof overvoltage protection (indoor type, outdoor type) is installed in overvoltage fault protector from the device, when the over-voltage protection fails failure, the protector from the device automatically from the system to prevent an explosion. Explosion-proof overvoltage protection and supporting the counter is fault-indicating JSZ-8 discharge counter, it can be given a normal and fault indication.
Energy capacity to withstand 600 ~ 800A type square wave flow capacity.
■Phase combined over-voltage protection Model comparison table
Currently phase combined over-voltage protection (three-phase modular surge arrester) is in the old model with the national standard JB / T8459-1996 "arrester Model methodology" model of the transition period, in order to facilitate customers to buy products at reasonable the selection, to avoid misunderstandings in use, the company will now market and use common models are listed below, with reference to use for the user.
