The 35KV zinc oxide arrester YH5WZ-51/134

Yueqing Deng Rui Electric Co., Ltd.supply various specifications of the [The 35KV zinc oxide arrester YH5WZ-51/134] products, providing professional [The 35KV zinc oxide arrester YH5WZ-51/134] prices, models, pictures, factory direct supplier prices have obvious advantages, find [The 35KV zinc oxide arrester YH5WZ-51/134] manufacturers, we chose Dengrui electrical, please contact us!


35KV oxide zinc arrester YH5WZ-51/134 the basic principles of
35KV the arrester YH5WZ-51/134 of zinc oxide is an over-voltage protection, mainly for the protection of power systems, railway electrification systems, communication systems in a variety of electrical equipment (transformers, switchgear, capacitors, traps, transformers, from atmospheric over-voltage generators, motors, power cables, etc.), operating voltage and power frequency transient overvoltage damage is the basis of the power system insulation coordination.
35KV zinc oxide surge arresters YH5WZ-51/134 its core components (varistors) with advanced formulations based on zinc oxide, has excellent non-linear (V - On) feature, that under the normal operating voltage, the current passing through only the microampere level, when subjected to over-voltage, the current passing through instantly reach thousands of amps, so that the arrester in a conduction state, the release of over-voltage energy, which effectively limits the over-voltage transmission and distribution equipment against . The 35KV the arrester YH5WZ-51/134 of zinc oxide has a steep wave response characteristics, the steep wave voltage without delay, the operation residual depression, there is no discharge dispersion, etc.. Makes the steep waves, greatly improve the operating wave protection margin, and insulation coordination, able to do the steep waves, lightning surge, the protection of the operating wave margin is nearly identical, and thus provide the best protection for electrical equipment.

35KV zinc oxide surge arresters YH5WZ-51/134 overall injection molding, two encapsulation process, good sealing performance, explosion-proof performance, resistance to dirty no-clean and can reduce the fog, the wet flash, resistance to electrical erosion, aging, small , by weight, easy to install and maintain. Porcelain bushing arrester replacements.

The 35KV zinc oxide surge arresters YH5WZ-51/134 technical standards
Production implementation of standards for the GB11032-2000 (eqv IEC60099-4: 1991)
Without gaps for AC metal oxide surge arresters ", JB/8952-2005 exchange system using composite
Coat gapless metal oxide surge arresters

The 35KV zinc oxide surge arresters YH5WZ-51/134 Features
1, small size, light weight, crashworthiness, transport collision damage, flexible installation, suitable for use in the switch cabinet;
2, the special structure of the overall molding molding, no air gap, good sealing performance, moisture proof;
3.Climb power distance, water repellency, stain resistance ability, stable performance, reduce operation and maintenance;
4.The unique formula of zinc oxide varistors, the leakage current is small, slow aging, and long service life.
5, in fact, with the DC reference voltage, square wave through flow capacity and large current tolerance is higher than the national standard.

The 35KV arrester YH5WZ-51/134 conditions of use
Ambient temperature -40 ° C ~ +40 ° C
The maximum wind speed does not exceed 35m / s
Altitude does not exceed 2000m
The seismic intensity is not more than 8 degrees
The ice cover thickness is not greater than 10 mm
Long-term applied voltage does not exceed its maximum continuous operating voltage
Radiation of the sun: solar maximum irradiation (1.1kW/mm2)
The impact of product type test to be considered, if the arrester
Other heat sources, the use of surge arresters to be a consultation between nearby.

The 35KV zinc oxide the arrester YH5WZ-51/134 user ordering Know
1, the arrester before installation should be stored in a clean, dry room. Shall be subjected to corrosive gases or liquids, corrosion.
2, Surge arresters in operation before the preventive test. Put into operation, should be regularly (10KV and below the arrester 5 years, 35KV and above arrester 2 years) to do the following test and reference to the Schedule to run before the data were compared; Notes
a measurement arrester insulation resistance;
b, measurement of arrester DC voltage 1mA;
c, measurement of 0.75 times the DC 1mA leakage current.
