Mercury-arc rectifiers or "converters" were used for charging storage batteries, arc lighting systems, the DC traction motors for trolleybuses, trams, and subways, and electroplating equipment. The mercury rectifier was used well into the 1970s, when it was finally replaced by semiconductor rectifiers. … Meer weergeven A mercury-arc valve or mercury-vapor rectifier or (UK) mercury-arc rectifier is a type of electrical rectifier used for converting high-voltage or high-current alternating current (AC) into direct current (DC). It is a … Meer weergeven Operation of the rectifier relies on an electrical arc discharge between electrodes in a sealed envelope containing mercury vapor at very low pressure. A pool of liquid mercury acts as a self-renewing cathode that does not deteriorate with time. The mercury emits Meer weergeven As solid-state metal rectifiers became available for low-voltage rectification in the 1920s, mercury arc tubes became limited to higher … Meer weergeven Special types of single-phase mercury-arc rectifiers are the Ignitron and the Excitron. The Excitron is similar to other types of valve … Meer weergeven In 1882 Jemin and Meneuvrier observed the rectifying properties of a mercury arc. The mercury arc rectifier was invented by Peter Cooper Hewitt in 1902 and further developed throughout the 1920s and 1930s by researchers in both Europe and North … Meer weergeven The construction of a mercury arc valve takes one of two basic forms — the glass-bulb type and the steel-tank type. Steel-tank valves were used for higher current ratings … Meer weergeven Single-phase mercury-arc rectifiers were rarely used because the current dropped and the arc could be extinguished when the AC voltage changed polarity. The direct … Meer weergeven Web20 okt. 2002 · 2002-10-20 5:26 am. #1. I am considering using a couple of 866A rectifiers in my next project (probably a transmitting tube amp.). These monsters use mercury vapour, and are rated up to 5000V. I will probably run them at ~800V and 200mA, not too huge. The main reason I want to use them is because I have access to a large store of …
