美国WATTEREDGE VCM,STANDARD,SS,POTTED,BOXED,INSPECTED WX33300
WX-33300 Rated 6.25kA, uses same contact material as WX but is constructed of epoxycoated stainless steel support plates. Used in metals refining applications where switch will be operated in a NO LOAD, i.e. power source turned off before opening, installation. Normally ceramic and diaphragm region is urethane-potted to reduce corrosive activity on metal component
美国WATTEREDGE WX-32823
WX-32823 "Standard" VCM, Rated 6.25kA. Support Plates constructed of Epoxy-Coated Cold Rolled Steel. This VCM has been the primary workhorse of Watteredge, Inc. switches, normally used in all Chlor-alkali mercury cell "fixed" switches, and most other non-metals refining applications. Proprietary alloy of contact material allows for 6.25kA rating vs. 5.0kA rating for most other VCM designs.
美国WATTEREDGE WX-34777
WX-34777 Rated 5.0kA, commonly referred to as a "High Energy" VCM. Contact material utilizes a proprietary alloy to offer good electrical conductivity, but to also limit the effects of high-energy arcing, normally experienced in ON LOAD opening in highlyinductive copper-refining bus systems. Support plates constructed of epoxy-coated stainless steel. Ceramic and diaphragm region urethane-potted to resist corrosive metal-refining environment.
美国WATTEREDGE WX-34778
WX-34778 Rated 5.0kA, same as WX-34777 but support plates are epoxy-coated cold rolled steel. Normally not potted. This VCM is solely for use in Watteredge, Inc. Matrix Portable Jumper Switch elements. The switch element is water cooled, allowing this VCM to carry between 7.0 and 12.5kA. The high energy contact material prolongs the life of the VCM as it operates in Matrix Jumper Switch assemblies shorting and opening on currents from 65kA to 170kA. The Watteredge, Inc. Matrix switch designates anywhere from one to four of these VCM's to be in the "sacrificial" position (one of the last contacts to open, taking the brunt of the electrical arc energy). Normally these contacts are changed out once every switch operations at full load (about 1 year of operation in a typical Chlor-alkali plant). Investigation of the contact faces after 300 + operations at full load has shown very acceptable performing as designed and expected.
