Conditions for normal operating environment:

  • Ambient air temperature: -5℃ ~+40℃  and the average temperature should not exceed +35℃  in 24h.

  • Air condition: With clean air. Relative humidity should not exceed 50% at +40℃  . Higher relative humidity is allowed at lower temperature. Ex. 90% at +20℃ . But in view of the temperature change, it is possible that moderate dews will produce casually. 

  •  Altitude above sea level should not exceed 2000M. 

  • The device is suitable to the transportation and store with following temperature :-25℃  ~+55℃  , in short time (within 24h) it reaches +70℃  . Under the limiting temperature, device should not suffer damage that can' t recover, and it can works normally under normal conditions.

  • If the above operating conditions not meet user's demand. Consult with manufactory.

  • Technical agreement should be signed additionally if the device is used for marine petrol drill taken platform and nuclear power station.

Regarding the transformation of permanent magnet circuit breakers in the 35kV switch room of 110kV substation in Luliang Oilfield
I. Equipment Dilemmas in Freezing WintersThe 35kV switch room of the 110kV substation in Luliang Oilfield, commissioned in 2002, has always been a key area for my maintenance team. The original ZN23-40.5/1600 vacuum circuit breakers, equipped with spring operating mechanisms, posed recurring challenges during subzero winters. With over 200 components and a 12-stage mechanical linkage, the spring mechanisms suffered severe wear on sliding friction surfaces. In temperatures as low as -40°C, lu

Brief Introduction to Thermal Generating UnitsElectricity generation relies on both renewable and non - renewable energy resources. Thermal generating units represent a conventional approach to power production. In these units, fuels such as coal, nuclear energy, natural gas, biofuel, and biogas are combusted within a boiler.The boiler of a generating unit is an extremely complex system. In its simplest conception, it can be visualized as a chamber whose walls are lined with pipes, through which
