XL-21 low-voltage power distribution cabinet is closed,the shell is made of steel plate bending,the knife switch operation handle is installed on the upper right column in front of the box,which can be used as a power switch.A voltmeter is installed in front of the distribution cabinet to indicate the voltage of the bus bar.There is a door in front of the power distribution cabinet.After the door is opened,all the equipment in the power distribution cabinet is open for easy maintenance.The power distribution cabinet adopts domestic self-designed components,with compact structure,easy maintenance,line scheme can be flexibly combined and so on.In addition to air circuit breakers and fuses for short circuit protection,the power distribution cabinet is also equipped with contactors and thermal relays,and the front door of the box can be equipped with operation buttons and indicators.
WORKING CONDITION:
◇Ambient temperature:-50℃~+40℃,and the average temperature within 24h does not exceed+36℃;
◇Altitude:no more than 2000m;
◇Relative humidity:no more than 50%when the ambient airhumidity is+40℃;
◇In the lower humidity can have a higher relative humidity (such as: +20℃ 90%),taking into account the change in temperature allows the production of moderate condensation;
◇The inclination of the vertical plane when the equipment is installed should not exceed 5°,and the equipment should be installed in a place without severe vibration,no impact and no corrosion.
