Product Description

Model HY5WS-17/50
This product is used to protect all kinds of electrical equipment in power system from overvoltage damage. Under normal operating voltage, only microampere-level current flows, when the overvoltage intrudes, the current flowing through the arrester increases rapidly, and the amplitude of the overvoltage is limited to release the overvoltage energy. After the overvoltage disappears, the zinc oxide arrester restores the high resistance state, so that the electrical equipment of the power system can work safely and normally. It has the advantages of small size, light weight, strong sealing performance and good anti-riot performance.

Overview:
The lightning arrester is the basis for the insulation of all kinds of electrical equipment in the power system (transformers, capacitors, generators, motors, PT, CT, circuit breakers, contactors, etc.), and the internal and external insulation indicators of all electrical equipment in the power system are determined by the protection performance of the lightning arrester (short-time power frequency voltage resistance, lightning impulse voltage resistance and operating impulse voltage resistance, etc.).

Metal oxide arrester (zinc oxide arrester) is the current limit overvoltage of the most advanced protective electrical appliances, widely used in power generation, transmission and distribution systems, to protect the insulation of electrical equipment from overvoltage damage. Its core components have excellent "nonlinear voltammetry" characteristics, which greatly improves the overvoltage current passing ability, thus bringing fundamental changes in the characteristics of the arrester.

10KV zinc oxide arrester, 10KV line arrester manufacturers when the arrester under the normal operating voltage, the current flowing through the arrester is only microamperes, when the overvoltage, due to the nonlinear zinc oxide resistance, the current flowing through the arrester instantaneous thousands of amperes, the arrester in the on-state, release the overvoltage energy, Thus, the damage of overvoltage to power transmission and transformation equipment is effectively limited.

The organic jacket metal oxide arrester is a scientific research result combining the technical advantages of the organic insulating material and the traditional porcelain jacket metal oxide arrester. It not only has the advantages of the porcelain jacket metal oxide arrester, but also has the advantages of good electrical insulation performance, high dielectric strength, leakage resistance, electric corrosion resistance, heat resistance, cold resistance, aging resistance, explosion proof, hydrophobic, good sealing performance and so on.

The core working element of the product is made of multicomponent metal oxide powder, which is mainly zinc oxide. It has nonlinear one-ampoule characteristic, fast wave response and large flow capacity. The product with gap adopts self-blowing gap and equivoltage irradiation structure, which reduces the dispersion of discharge and has small impact coefficient.

The use of composite insulation jacket conforms to the development trend of miniaturization, safety and maintenance-free of international power products. Compared with traditional inorganic materials such as ceramic and glass, polymer organic composite has the advantages of small size, light weight, anti-pollution and anti-cleaning, explosion-proof and shock-proof. It is the preferred lightning protection element in the integrated and modular medium and high voltage power transmission and transformation equipment.

HY5WS-10kV zinc oxide arrester is suitable for 220kV and below AC power generation, transmission, power transformation, distribution system, used to limit the amplitude of lightning and system internal operation of overvoltage electricity to the specified level, is the basic equipment of the entire system insulation. It is the preferred lightning protection element in the integrated and modular medium and high voltage power transmission and transformation equipment.

10KV zinc oxide arrester, 10KV line arrester manufacturer HY5WS-17/50 must be installed vertically, due to the long-term stress caused by its own weight and lead, horizontal or inclined installation of the arrester will inevitably lead to the tensile strength of its jacket decline, not only to the insulation seal of the arrester caused a serious threat, and even cause the possibility of lightning arrester fracture. The dust in the air is easily attached to the surface of the insulation jacket and the upper and lower electrodes of the insulator, resulting in uneven voltage distribution on the surface of the outer insulator and reduced scintillation voltage along the surface. In the case of drizzle, fog and dew and other humid weather, the upper surface of the insulation jacket will not only be wet, but also the water film will cause the penetration of the upper and lower electrodes of the outer insulator, further worsening the flashover voltage along the surface. This eventually leads to a surface breakdown of the entire insulating jacket. When the line or equipment is subjected to atmospheric overvoltage and internal overvoltage, the electric power accompanied by a strong current is undoubtedly worse for the horizontal or inclined installation of the power arrester, which intensifies the damage to the insulation seal of the zinc oxide arrester, further shortening the service life of the zinc oxide arrester.
