The CMM-6D<\/strong> degassing unit is designed for removal of particulate matter as well as heat and vacuum purification of electric insulating and turbine oils from water and gas.<\/p>\n The unit is intended for use during installation, repairs and operation of oil-filled high voltage equipment up to 1150 kV (power transformers, high voltage switches etc).<\/p>\n For indoor operation, ensure exhaust of removed gases into the atmosphere via piping.<\/p>\n Parameters<\/strong><\/p>\n<\/td>\n Value<\/strong><\/p>\n<\/td>\n<\/tr>\n 2-<\/em><\/strong>6<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n 2-<\/em><\/strong>6<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n 0,5<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n 5<\/em><\/strong>.<\/em><\/strong>0<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n 0,5<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n 9<\/em><\/strong>0<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n 0<\/em><\/strong>.<\/em><\/strong>35<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n 142<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n 1<\/em><\/strong>50<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n 10<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n 5<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n 10<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n 380<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n 6<\/em><\/strong>0<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n 3700<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n 1750<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n 2320<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n 2250<\/em><\/strong><\/p>\n<\/td>\n<\/tr>\n Note – <\/em><\/strong> *<\/em> initial oil parameters:<\/p>\n The unit is a self-contained unit with all assemblies and components in the container. The container is installed on a trailer. Side walls of the container feature doors for simple access and ventilation. A compartment for tools and accessories is attached to the side wall of the unit; the compartment also contains drums with power cable and oil hoses.<\/p>\n The unit consists of the vacuum chamber 1<\/em><\/strong>, oil pump 2<\/em><\/strong>, metal body 3<\/em><\/strong>, pre-filter 4<\/em><\/strong>, fine filters 5<\/em><\/strong>, oil trap 6<\/em><\/strong>, oil heater 7<\/em><\/strong>, piping with valves, vacuum pump section and the control cabinet 8<\/em><\/strong>.<\/p>\n The vacuum pump section is an assembly of two vacuum rotary vane pumps 9<\/em><\/strong>. The section is connected to the vacuum chamber (1<\/em><\/strong>) and trap (6<\/em><\/strong>) via vacuum line 11 <\/em><\/strong> with cutoff valve 12<\/em><\/strong>. Pump exhausts are connected to collector 13<\/em><\/strong> and lead out to the back wall of the container.<\/p>\n Figure 1.3 <\/em>Unit general view <\/strong><\/p>\n Tool and accessory compartment 10 <\/em><\/strong>is attached in the side of the container, containing cables and hoses. The vacuum chamber can be cut off from the oil pump with disk gate 14<\/em><\/strong>. Oil supply collector 15<\/em><\/strong> and oil outlet collector 16<\/em><\/strong> are located next to each other.<\/p>\n Parameters are controlled by: \u0422\u0421\u041c<\/em> type thermistors,<\/em> thermostat, flow relay, pressure and vacuum sensors, level sensors and oil flow meter\/totalizer.<\/em><\/p>\n Pre-filter (mesh) 4<\/em><\/strong> installed at the inlet to remove particulate matter from the oil. Fineness of filtration is defined by 200 micron brass mesh installed in the case. To rinse the filter element, the filter is removed from the case and rinsed in clean transformer oil.<\/p>\n The oil pump 2<\/em><\/strong> removes oil from the vacuum chamber. The pump is controlled from the control panel.<\/p>\n Fine filters 5<\/em><\/strong> (figure 2) are installed for filtration of the processed oil with 1 micron fineness. For general view of the filter refer to Figure 2.<\/p>\n Figure 2\u00a0\u00a0\u00a0\u00a0 Fine filter: 1<\/em><\/strong> \u2013 body; 2<\/em><\/strong> \u2013 lid; 3<\/em><\/strong> \u2013 oil inlet; 4<\/em><\/strong> \u2013 clean oil outlet; 5<\/em><\/strong> \u2013 pressure sensor before filter; 6<\/em><\/strong> \u2013 pressure sensor after filter; 7<\/em><\/strong> \u2013 contaminant drain valve; 8<\/em><\/strong> \u2013 air release valve<\/p>\n The filter consists of lid and body supporting the filter element. The lid features a valve designed to remove air from the filter when filling with oil and to let the air in when the oil exits the filter. A tap is installed in the lower part of the body. Oil inlet and outlet are welded into the body, as well as connectors for pressure sensors to indicate pressure before and after the filter element and the pressure drop.<\/p>\n To replace the filter element, drain contaminants from the cartridge filter by opening the valve 7. Unscrew the bolts on the lid 2 and remove it from the filter, unscrew the hold down nut, remove filter element. Install new filter element, secure it with the hold down nut. Install the lid and secure with bolts.<\/p>\n The oil heater 7<\/em><\/strong> (figure 3) is a cylinder with installed pipes with ceramic heating elements, inlet and outlet. For general view of the heater, refer to figure 3.<\/p>\n Figure 3 <\/em><\/strong>Oil <\/em><\/strong>heater: 1<\/em><\/strong> \u2013 heater body; 2<\/em><\/strong> \u2013 pipes for installation of heating elements; 3<\/em><\/strong> \u2013 ceramic heating element; Specifications<\/strong><\/h2>\n
