Low voltage arrester
1. Product overview
Metal oxide arrester (hereinafter referred to as arrester) is an over-voltage limiter. When over-voltage occurs, the voltage between the two terminals of the arrester does not exceed the specified value, so that electrical equipment is protected from over-voltage damage; after the over-voltage effect, it can Return the system to normal status quickly.
2. Structural characteristics
Metal oxide arresters are mainly composed of zinc oxide resistors with excellent volt-ampere characteristics, upper and lower electrodes and jackets.
Composite jacket arresters have the following characteristics:
1) Fundamentally solve the sealing problem;
2) The composite jacket is weather-aging resistant, has a wide operating temperature range, is highly hydrophobic and has recovery and migration characteristics. It can operate normally in harsh climates such as high altitudes and heavy pollution, and can prevent vicious explosion accidents;
3) The external metal parts are made of high-strength alloy aluminum and other anti-corrosion materials, so the pre-test period can be extended or no maintenance is required during the service life;
4) Small size and light weight.
Electric porcelain jacket arresters have the following characteristics:
1) The arrester adopts two structures: normal pressure and micro-positive pressure, and is filled with high-purity dry nitrogen or SF6 gas inside. The slight positive pressure makes the internal gas pressure of the arrester slightly greater than the atmospheric pressure, making it difficult for external moist gases to enter its interior, which greatly improves the moisture resistance of the arrester;
2) The main components of the arrester are sealed and leak-detected using a helium mass spectrometer leak detector;
3) The arrester is equipped with a pressure release device. When the arrester operates under abnormal circumstances and the internal air pressure rises, the internal pressure can be released in time to avoid secondary accidents.
3. Normal operating conditions
1) The ambient temperature is not higher than +40℃ and not lower than -40℃;
2) Sunlight radiation;
Note: The influence of the maximum solar irradiation (1.1kW/m2) has been considered by preheating the sample during the type test. If there are other heat sources near the arrester, the use of the arrester needs to be negotiated by the supplier and the buyer.
3) The altitude does not exceed 1000m;
4) The frequency of the power supply is not less than 48Hz and not more than 62Hz;
5) The power frequency voltage applied between the terminals of the arrester for a long time should not exceed the continuous operating voltage of the arrester;
6) Areas with earthquake intensity of 7 degrees and below;
7) The maximum wind speed does not exceed 35m/s.
