Product Description

TBP three-phase combined overvoltage protector

Overview
Three-phase combined overvoltage protector (three-phase combined surge arrester) is used to protect the insulation of electric equipment from overvoltage hazards of the protection of electrical appliances, is a new type of surge arrester, which is characterized by limiting the overvoltage between the phase and the ground at the same time, but also effectively limit the overvoltage between the phases, which is not possible to do with ordinary surge arrester. It is widely used to protect vacuum switches, rotating motors, shunt compensation capacitors, power plants, substations and so on. This combination protector adopts large-capacity zinc oxide resistor as the main component inside, which has good volt-ampere characteristics and over-voltage absorption ability, and can provide reliable protection for the protection equipment, which is very popular with the electric power system.

Execution standard
This product implements the national standard GB11032-2000 "AC non-gap metal-oxide surge arrester", JB/T10496-2005 "AC three-phase combined non-gap metal-oxide surge arrester", ZBK49005-90 "AC system with series gap metal-oxide surge arrester", JB/T8459-1996 "surge arrester product modeling method".

Structural features
1,The structure is novel and unique, with four-element star connection, excellent technical performance, high voltage insulation, and greatly utilizing and reducing the use of space;
2,The composite jacket is molded as a whole, with good sealing, explosion-proof, moisture-proof performance, anti-leakage marks, anti-electro-erosion, dirt-resistant, and good water repellency;
3,High-voltage cable wiring to ensure insulation strength and flexible installation;
4,Small volume, light weight, save space, especially suitable for installation in a variety of switchgear (the company's product design is unique, can be installed vertically, can also be installed horizontally.)

Use conditions
1,Altitude not greater than 2000M;
2,Ambient temperature: -40ºC~+40ºC;
3,Power frequency: 48Hz~62Hz;
4, long-term applied to the protector of the industrial frequency voltage does not exceed the protector's continuous operation voltage;
5,Maximum wind speed does not exceed 35m/s;
6, seismic rupture degree 7 degrees and the following areas;

Use selection
Three-phase combined overvoltage protector is divided into gapless type and series gap type, the use of the difference is: gapless overvoltage protector, as long as the system has an overvoltage, can be well absorbed and suppressed; and gap-type overvoltage protector, only the overvoltage on the system energy reaches the overvoltage protector to break through the series gap in the overvoltage protector and discharge, gap-type overvoltage protector will be acted upon.
Therefore, it is recommended that users in the selection of: regular selection of non-gap type over-voltage protector, the system disturbing voltage is too large or the switch frequently close the place to choose a gap type over-voltage protector is appropriate.
