Indoor armored fixed metal enclosed switchgear (hereinafter referred to as switchgear), suitable for 12kV and below three-phase AC 50Hz power system. As a complete set of power distribution devices within the user to receive and distribute electric energy, it is mainly used in power plants, industrial and mining enterprises to distribute power, and power substation in the power system, and the control and protection of motors and transformers. The feature of this product is that it can achieve "three cabinets in parallel", that is, the circuit breaker cabinet, load switch (fuse - combination electrical appliance) cabinet, vacuum contactor cabinet three schemes have the same dimensions, and the busbar connection is consistent.
The ambient air temperature does not exceed 40 ° C, and the average value measured within 24 hours is not more than 35ºC, the minimum is not less than -15ºC;
The altitude is not more than 1000m
Temperature conditions A relative humidity: the daily average does not exceed 95%; The monthly average does not exceed 90%
Steam pressure: the average daily value does not exceed 2.2kPa; The monthly average does not exceed 1.8kPa.
The surrounding air is not significantly exposed to dust, smoke, corrosive and/or combustible gases
Contamination by body, steam or salt spray.
When the switchgear is installed at an altitude higher than 1000m, the ordering party shall comply with the requirements manufacturers shall consult to take necessary insulation measures.
When the maximum ambient temperature exceeds 40 ° C, the rated current carrying capacity of the switch cabinet is set the goods must be reconfirmed by the manufacturer.
The unique structure makes the cabinet no longer use organic insulation materials, but use air as the main insulation
The key point of heating in the switch cabinet, the isolation contact is completely exposed to the outside face, and can be directly observed and measured from the front of the cabinet, which is conducive to heat dissipation and can ensure the safety of operation
The protection grade of the switchgear shell is large IP40 and the compartment IP30, which meets the IP20 required by the GB3906-2006 compulsory standard
Because the switchgear can be maintained and overhauled on the front, the installation against the wall will not affect any use
