Environmental conditions for use
Altitude:≤1000m;
Environment temperature:The upper limit of the ambient air temperature is+40℃,and the lower limit is -15℃;
Relative humidity:The daily average valueshall not exceed 95%,and the monthly average value shall not exceed 90%;
Installation site:A place without conductive dust,corrosive gases,and water vapor;Places without fire and explosion hazards;Places without frequent severe vibration.
Note: When the normal usage conditions mentioned above cannot meet the usage requirements, the user shall negotiate with the manufacturer.div容器Structural characteristics
The ring main unit is assembled with 8MF profiles,and the safety module hole E of the entire structure is 20mm;
The ring main unit is equipped with FZRN25-12D switch,FKRN12A-12D switch,GN30-12 switch, and VS1 fixed circuit breaker
The load switch,isolation switch,VS1 circuit breaker,and cabinet door have complete and reliable mechanical linkage and interlocking devices,which can effectively prevent misoperation and ensure safe maintenance.
The switch can be manually and electrically operated
The cabinet door and instrument door of measurement cabinet are equipped with lead sealing pins. The fuse combination electrical cabinet and fuse tube are equipped with striker pins.In the case of a short circuit,the striker impacts the tripping mechanism,achieving fast switching and effectively protecting electrical equipment;The ring main unit adopts front operation and reliable wall installation Power transmission operation:Only when the cabinet door is closed and locked,and the grounding switch is operated to the "open"position,that can the load switch be operated to the closed position. Power outage operation:The grounding switch can only be closed when the load switch is in the opening position,and the cabinet door can only be opened when the grounding switch is in the closing position.
The isolation knife is reliably interlocked with the circuit breaker and is interlockedwith the door fully meeting the five prevention requirements.
