TBP-A (B, C) -12.7/131-J over-voltage protection device with a counterDetails:

Electric Co., Ltd. Yueqing Dengrui factory direct【TBP-A-12.7/131-J over-voltage protection】,And provide a variety of【TBP-A-12.7/131-J over-voltage protection】Images, parameters, description and other detailed product information,Dengrui【TBP-A-12.7/131-J over-voltage protection】High quality, excellent price, special requirements can be customized consultation.

TBP-A (B, C) -12.7/131-J counter with over-voltage protection is mainly used for protection of 10KV power system in a variety of electrical equipment against atmospheric over-voltage, over-voltage and transient over-voltage frequency damage is the basis of power system insulation coordination. 

Product Overview
Three-phase modular composite MOA is a new type of insulation used to protect electrical equipment against over-voltage protection of electrical hazards, relative to its limit over-voltage between the same time, effective on the white over-voltage limit. 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 measures to limit over-voltage phase. Arrester internal use large-capacity zinc oxide varistor as the main component, has a good volt-ampere characteristics and the ability to absorb the over-voltage on the protected equipment to provide reliable protection, power system has been widely used.
Implementation of standards
This product implementation GB GB11032-2000 "metal oxide surge arresters without gaps for AC", composite coat products simultaneously JB/T8952-2005 "communication system with composite coat metal oxide surge arresters without gaps", JB / T 10496-2005 "exchange three combined with metal oxide surge arresters without gaps ", JB / T 8459-1996" arrester Model methodology. " 

Structural features
1, with four star connection device designed so that each phase, the phase have been over-voltage protection; structural clever with them to play a combined six ordinary lightning arrester role, while overcoming three phases over-voltage arrester can not protect the shortcomings.
2, the modular structure, small size, light weight, flexible installation, use and greatly reduced the use of space; particularly suitable for installation in switch cabinet.
3, molded silicone rubber coat forming a whole, has a good seal, stain resistance, explosion-proof, moisture resistant, high dielectric strength, resistance to leakage marks, anti-electric corrosion, heat, cold, anti-aging.
4, no gap can be combined arrester type, it can be a series gap type. 

Conditions of Use
a, is not greater than 2000 m above sea level b, ambient temperature: -40 ℃ ~ +40 ℃
c, maximum wind speed of not more than 35m/sd, seismic intensity of 7 degrees and the following areas
e, applied to the arrester on the long-term frequency voltage does not exceed the arrester continuous operating voltage
f, Power frequency: 48Hz ~ 62 Hz
User Information
1, transport, storage, unpacking and installation, not a strong impact; the appearance of pre-use check is intact.
2, put into operation before the measurement DC.U1mA, its value shall not be less than the manufacturer specified value; measurement of leakage current under 75% U1mA IX, IX50μA; put into operation on a regular basis (5 years) measured a DC.U1mA, with the initial value, change rate not greater than ± 5%;
3, no special maintenance and cleaning. 

Order Information
1, product technical performance and parameters, product dimensions and installation dimensions see Dengrui electrical product samples;
2, the indoor type carried by cable standard length 60cm, also available upon request.
3, according to user needs, the modular structure offers several shape to facilitate user selection of arrester; if the user's model or shape the structure and the sample does not match, you can specify when ordering, so the company designed and manufactured to meet user requirements .
