The zinc oxide lightning arrester tester under UHV power can help many power workers conduct various power tests more conveniently.

1. Zinc oxide lightning arrester has a large current capacity

This is mainly reflected in the ability of lightning arresters to absorb various lightning overvoltages, power frequency transient overvoltages, and operating overvoltages. Tuopu Electric's current carrying capacity fully meets or even exceeds the requirements of national standards. The discharge level, energy absorption capacity, 4/10 nanosecond high current tolerance, and 2ms square wave current capability of the circuit have all reached the advanced level in China.

2. Zinc oxide lightning arrester has excellent protection characteristics

Zinc oxide lightning arrester is an electrical product used to protect various electrical equipment in the power system from overvoltage damage, with good protection performance. Due to the excellent nonlinear volt ampere characteristics of zinc oxide valve plates, only a few hundred microamperes of current pass through under normal operating voltage, making it easy to design a gapless structure with good protection performance, light weight, and small size. features.

When overvoltage invades, the current flowing through the generator rapidly increases, and the amplitude of the overvoltage is first processed to release the energy of the overvoltage. Afterwards, the zinc oxide valve returns to a high resistance state, allowing the power system to operate normally.

3. Zinc oxide lightning arrester has good sealing performance

The lightning arrester components have good aging performance. The high-quality composite jacket with good air tightness adopts measures such as controlling the compression of the sealing ring and adding sealant. Using ceramic sheath as the sealing material to ensure reliable sealing and stable performance of the lightning arrester.

4. Mechanical properties of zinc oxide lightning arrester

Mainly consider the following three factors: 1) the seismic force it bears; 2) The maximum wind pressure acting on the lightning arrester: 3) The maximum allowable tensile force of the conductor borne by the top of the lightning arrester.

5. Zinc oxide lightning arrester has good cleaning performance

The gapless zinc oxide lightning arrester has high pollution resistance. The current national standard specifies a creepage distance level of 20mm/kV for Class II medium pollution areas; Grade III heavily polluted area: creepage distance of 25mm/kV; Grade IV extremely heavily polluted area: creepage ratio of 31mm/kV;

6. High operational reliability of zinc oxide lightning arrester

The reliability of long-term operation depends on the quality of the product and whether the product selection is reasonable. The quality of its products is mainly affected by the following three aspects: 1) the rationality of the overall structure of the lightning arrester; 2) The volt ampere characteristics and aging resistance of zinc oxide valve plates; 3) The sealing performance of lightning arresters.

7. Power frequency withstand voltage capability of zinc oxide lightning arrester

Due to various reasons such as single-phase grounding, long line capacitance effect, and load in the power system, it can cause an increase in power frequency voltage or generate transient overvoltages with large amplitudes. The lightning arrester can withstand a certain frequency voltage for a certain period of time. Increase capacity.
