It is better than all other media except air and SF6, which apply at high pressure.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When an arc is opened by moving apart from the contacts in a vacuum, an interruption occurs at the first current zero. With the arc interruption, their dielectric strength increases up to a rate of thousands of times as compared to other breakers.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Vacuum_Circuit_Breaker_Operation\"><\/span><strong>Vacuum Circuit Breaker Operation<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">It is an electrically operated switch. There is no overcurrent devices built-in. The overcurrent protection and control comes from using the current transformer (CT) and protective relays that are mounted in the switchgear assembly. Power supplies from a control source, batteries, or control power transformer external to the breaker assembly.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When a fault occurs in the system, the contacts of the breaker are moved apart, and hence the arc is developed between them. When the current-carrying contacts are pulled apart, the temperature of their connecting parts is very high due to which ionization occurs. As a result of ionization, the contact space which is discharged from the contact material is filled with a vapor of positive ions.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The density of vapor depends on the current in the arcing. Due to the decreasing mode of current wave rate of release of vapor fall, and after the current zero, the medium regains its dielectric power provided vapor density around the contacts reduced. Hence, the arc does not restrike again because the metal vapor is quickly removed from the contact zone.<\/span><\/p>\n<figure id=\"attachment_20387\" aria-describedby=\"caption-attachment-20387\" style=\"width: 612px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-full wp-image-20387\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/11\/Vacuum-Circuit-Breakers-1.jpg\" alt=\"Vacuum Circuit Breakers\" width=\"612\" height=\"444\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/11\/Vacuum-Circuit-Breakers-1.jpg 612w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2020\/11\/Vacuum-Circuit-Breakers-1-300x218.jpg 300w\" sizes=\"(max-width: 612px) 100vw, 612px\" \/><figcaption id=\"caption-attachment-20387\" class=\"wp-caption-text\">Parts of a vacuum circuit breaker (Reference: <strong>technicalbookspdf.com<\/strong>)<\/figcaption><\/figure>\n<p><span style=\"font-weight: 400;\">The actual application of the <\/span><span style=\"font-weight: 400;\">vacuum circuit breaker rating<\/span><span style=\"font-weight: 400;\"> depends on the CT ratio and the relay settings.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Advantages_of_Vacuum_Circuit_Breaker\"><\/span>Advantages of Vacuum Circuit Breaker<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Since the advent of <\/span><span style=\"font-weight: 400;\">vacuum circuit breakers<\/span><span style=\"font-weight: 400;\"> in the early 1960s, the technical parameters of vacuum circuit breakers have been continuously improved, with excellent performance and outstanding performance.

Closing bounce will not only end to high over voltages that affect the stable operation of the power grid but also cause contact burn-out or even welding when the capacitor bank generates inrush current and short-circuit closing. Opening bounce will reduce the distance between the contacts after the arc, leading to a breakdown, and the consequences are so significant.<\/span><\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Vacuum_Circuit_Breaker_Applications\"><\/span>Vacuum Circuit Breaker Applications<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The vacuum circuit breaker is today recognized as the most reliable current interruption technology for medium voltage switchgear.
