जिंक ऑक्साइड सर्ज अरेस्टर स्थापित करने की सही प्रक्रिया क्या है??
The जिंक ऑक्साइड बन्दी मुख्य घटक के रूप में जिंक ऑक्साइड प्रतिरोध का उपयोग करता है, जो अरेस्टर की वोल्टामेट्रिक विशेषताओं में काफी सुधार करता है और थ्रू-करंट क्षमता को बढ़ाता है. जब गिरफ्तारकर्ता सामान्य ऑपरेशन में हो, अरेस्टर धारा के माध्यम से वोल्टेज प्रवाह केवल माइक्रोएम्पीयर है. जब ओवरवोल्टेज प्राप्त होता है, बन्दी की उत्कृष्ट गैर-रेखीय विशेषताएँ एक अच्छी भूमिका निभाती हैं.
लाइटनिंग अरेस्टर का उपयोग मुख्य रूप से बिजली के उपकरणों को बिजली के घुसपैठ ओवरवॉल्टेज से बचाने और इसके बिजली उपकरण इन्सुलेशन क्षति पर ओवरवॉल्टेज संचालित करने के लिए किया जाता है।.
How To Install And Use The Zinc Oxide Arrester Correctly?
- Before the installation of the zinc oxide surge arrester, need to correctly check the content of the nameplate, whether it is in line with the rated voltage of the required system.
- The arrester is fixed on the bracket, the upper terminal is connected to the हाई-वोल्टेज लाइन, and the lower terminal needs to be reliably grounded.
- To avoid using the arrester as a bracing insulator, it should be installed as close as possible to the protected equipment so that it can achieve a better protective effect.
- Lightning arrester terminal installed in the drop fuse after, conducive to open when it plays a protective role, transformer low-voltage side should be installed low-voltage arrester, to prevent positive and negative transformation caused by overvoltage damage to power equipment.
- Zinc oxide arrester in the user needs to pay attention to the use of the location, तापमान, नमी, and lightning arrester that is not suitable for installation in large vibration or serious dirt and corrosive gas places.
- Zinc oxide lightning arrester in use needs to be regularly preventive testing, measuring leakage current. And require leakage current within the normal range of product regulations.
The Characteristics Of The Zinc Oxide Arrester Are As Follows.
- Basically no renewal current, strong resistance to multiple lightning shocks, or multiple operating wave capacity.
- Symmetrical voltammetric characteristics, positive and negative overvoltage protection level is equivalent.
- Zinc oxide can be used without series gaps, fast action, flat voltammetric characteristics, low residual voltage, and no intercept wave.
- Zinc oxide valve can be used in parallel, easy to achieve increased through-current and reduced residual voltage, to provide convenient assembly into ultra-high voltage surge arresters.
- It can reduce the level of insulation of the protected equipment.
- Simple structure, छोटे आकार का, लाइटवेट, available building block assembly simple.
- 35के.वी zinc oxide arrester shell can be made of synthetic silicone rubber, with explosion-proof ability, and not easy to penetrate moisture.
- The zinc oxide valve piece has excellent non-linear voltammetric characteristics. After using this gapless arrester, its protection level is not limited by the gap discharge characteristics. Make it depends only on the lightning and operating discharge voltage when the residual voltage characteristics and this characteristic is much better compared with the conventional silicon carbide valve plate. This relatively improves the insulation level of the transmission and substation equipment, thus making it possible to reduce the project cost.
