Extinguishing The Arc in a Vacuum Environment

In a vacuum arc-suppression device, the contacts diverge in a negative pressure environment where the air density is very low. For exapmle, vacuum interrupter of Tavrida Electric contain high vacuum (10-6 Pa). The free path of a molecule reaches 50 m, and the free path of an electron reaches 300 m. Under such conditions, the electrical breakdown between the electrodes is difficult due to the absence of charge carriers. The breakdown voltage of a 1 mm long gap in vacuum reaches 100 kV. The process of combustion and extinguishing of the arc in a vacuum at alternating current is as follows. When the contacts open, the contact pressure continuously decreases and the transient resistance of the contacts increases and tends to infinity at a pressure equal to zero. Even at low currents at the moment of opening the contacts because of the release of large amounts of heat contact material melts and a liquid metal bridge is formed, which under the influence of high temperature heats up

Modernization of Complete Switchgears With Tavrida Electric Reclosers

Today, few publications devoted to the problems of the electric power industry do not touch upon the concept of "SMART GRID," which literally translates as "smart grid. This concept implies a new technology for controlling the power system , starting from the energy producer and ending with its end consumers. That is why the first term "SMART" is also regarded as an acronym for "Self Monitoring Analysis and Reporting Technology," and why we will use the term "SG" instead for short. The tasks solved by "SG" are traditional - energy saving and uninterrupted energy supply. Such tasks were set before, but the possibilities of its realization with the advent of such means of communication as the Internet have become truly revolutionary.

Comparing Volume of Waste: Fuel vs Battery

Total fuel consumption of U.S. airlines is approximately 19 billion gallons annually. Total fuel consumption for mining Ore for construction of electric car batteries is approximately 21 billion gallons annually. The 21 billion gallons of fuel burned can only produce enough Ore to build 250,000 electric car batteries. The lifespan of an electric battery is 10 years and is not renewable in the sense of charge state. If more efforts to recycle are not introduced, by 2050 these batteries will fill landfills with 50 million pounds of waste that does not break down. I wonder if people would still believe in electric power cars, vehicles or equipment if they knew how massive the carbon emissions footprint really was?
