概述 

近年來，隨著我國城市電網(wǎng)的不斷擴(kuò)大及用電負(fù)荷的迅猛增長，同時(shí)針對(duì)農(nóng)村電網(wǎng)供電線路長、線損大的特點(diǎn)，原有的10kV電壓等級(jí)配電已經(jīng)難以滿足供電要求，逐漸暴露出其供電距離過大、線損率高、電壓質(zhì)量難以合乎要求等弱點(diǎn)。而采用20kV電壓等級(jí)供電具有增加供電能力、保證電壓質(zhì)量、降低電網(wǎng)電能損耗、節(jié)省電網(wǎng)的建設(shè)費(fèi)用等一系列優(yōu)勢(shì)。所以采用20kV電壓配電等級(jí)供電是發(fā)展的必然趨勢(shì)，勢(shì)在必行。ZW□-24型戶外高壓交流真空斷路器是三相交流50Hz、額定電壓為24kV的戶外開關(guān)設(shè)備，適用于開合各種不同性質(zhì)的負(fù)荷及頻繁操作場(chǎng)合，適用于城網(wǎng)、農(nóng)網(wǎng)、礦山及鐵道等的電力設(shè)備建設(shè)和改造。該產(chǎn)品是在吸納*進(jìn)技術(shù)，立足于國產(chǎn)原材料和工藝的基礎(chǔ)上，早研制成功的適合我國國情的24kV戶外高壓開關(guān)設(shè)備，擁有自有知識(shí)產(chǎn)權(quán)和多項(xiàng)專li技術(shù)，*了國內(nèi)24kV電壓等級(jí)戶外開關(guān)設(shè)備的空白，同比同類產(chǎn)品具有小型化、免維護(hù)、智能化等特點(diǎn)。同時(shí)該產(chǎn)品對(duì)周圍環(huán)境無污染，是綠色環(huán)保產(chǎn)品。 ZW32-24KV桿上小型化高壓真空斷路器

Summary

In recent years, with the continuous expansion of China's urban power grid and the rapid growth of electricity load, and in view of the characteristics of long power supply lines and large line losses in rural power grids, the original 10 kV voltage distribution has been difficult to meet the requirements of power supply, and gradually exposed its weaknesses such as too large power supply distance, high line loss rate, and difficult to meet the requirements of voltage quality. The use of 20kV voltage level power supply has a series of advantages, such as increasing power supply capacity, ensuring voltage quality, reducing power loss of power grid and saving construction costs of power grid. Therefore, the use of 20kV voltage distribution grade power supply is the inevitable trend of development, it is imperative. ZW-24 outdoor high-voltage AC vacuum circuit breaker is an outdoor switchgear with three-phase AC 50Hz and rated voltage of 24 kV. It is suitable for opening and closing various loads and frequent operation occasions, and for the construction and transformation of power equipment in urban power network, rural power network, mines and railways. This product is based on the advanced technology of foreign countries and domestic raw materials and technology. It is the earliest developed 24kV outdoor high voltage switchgear suitable for our national conditions. It has its own intellectual property rights and patented technology. It fills the gap of domestic 24kV Outdoor Switchgear with voltage level. Compared with the similar products in the world, it has the characteristics of miniaturization, maintenance-free and intellectualization. At the same time, the product has no pollution to the surrounding environment and is a green environmental protection product.
