GlobeCore\u2019s CMM plants feature the following safety devises which ensure simple and reliable operation and will safely shut down the system in case of any alarm situation:<\/p>\n
High Level Alarm<\/strong> – will alert plant\u2019s operator by activating sound and light alarms and shut down the system safely should high level of oil persist.<\/p>\n
Low Level Alarm<\/strong> \u2013 interlocked with the inlet pump low level alarm will safely shut down the plant in case of insufficient oil level.<\/p>\n

OPERATIONAL PRINCIPLE<\/strong><\/h2>\n
The unit can be operated in the following modes:<\/p>\n
- \n
- oil heating and filtration<\/li>\n
- filtration, heating and thermo-vacuum oil purification<\/li>\n
- vacuummising of a transformer tank<\/li>\n<\/ul>\n
Heating and filtration mode: <\/strong> oil goes through the unit via valve K1, mesh filter \u0420F, valve K10 pumped by oil pump P1 through the oil heater MN, cartridge filter F1, ball valve K2, K5 to the unit output.<\/p>\n
Filtration, heating and thermo-vacuum oil purification:<\/strong> transformer oil is fed through valve K1, mesh filter \u0420F, valve K10, oil pump P1 through oil heater MN, cartridge filter F1. Heated to temperature (50\u202660\u00ba\u0421) and purified from mechanical impurities oil is fed through ball valve K3, comes into vacuum column CV, passes through coalescers. Vacuum in the chamber is created by vacuum pump VP. Vacuum value in the chamber is maintained by means of the valve \u041a11 and controlled by vacuum gage VM. Air is supplied into chamber through moisture eliminator FV, ascending air carries out gases and water vapour from the oil surface and in this way the oil is dried. Wet air is subsequently removed into atmosphere via vacuum pump. Oil from the column is fed to the transformer by oil pump P2 through valves K8, K9, cartridge filter F2, return valve SV and ball valve K5 into the tank for clean oil. The K3 valve establishes necessary flow rate. The vacuum in the column is created by vacuum pump VP1 and maintained at 0,8 bar during operation.<\/p>\n
Vacuumizing of transformer<\/strong>: is carried out by pump VP through valve for vacuumizing of the external equipment.<\/p>\n
