Product advantage
> Leading technology
- Standard anti-corrosion and salt spray environmental plan to meet the stringent environmental requirements of the site
- The cabinet rack is a combined assembly structure, which is welded free structure with special-shaped steel and Angle plate positioning bolt connection, which improves the installation accuracy
- It can be equipped with circuit breakers of various brands at home and abroad, such as Chint NXM series, ABB TMAX series, Schneider NSX series, etc
- High breaking capacity, good dynamic and thermal stability, advanced structure, any combination of various scheme units
- The single cabinet contains more loops, saving the ground area, easy maintenance and high level of security protection (IP30)
> Cabinet put oneself in another's position
- Adopts 2-3mm high quality cold rolled hot dip galvanized sheet as a whole
- Laser numerical control equipment cutting, drilling, bending, to ensure the processing accuracy
- The exterior is coated with electrostatic epoxy powder, which will not take off paint for 50 years
- Molding size, hole size and equipment interval are modularized (modulus E=20mm).
- The cabinet rack is divided into bus, functional unit and cable, which are separated from each other to prevent the spread of accidents and facilitate live maintenance
> Functional unit (drawer part)
- Functional unit: feeding unit, motor unit, public power unit
- The door panel of the compartment is mechanically linked with the drawer by the operating mechanism of the main switch. When the main switch is closed, the door panel cannot be opened
- The operating machinery of the main switch can be locked in the closing or opening position by a picklock, so that the maintenance of electrical equipment can be carried out safely
- The back of the function unit is provided with the inlet and outlet plug of the main circuit, secondary plug of the auxiliary circuit and grounding plug
- The grounding plug enables the drawer to protect the continuity of the circuit when separating the test connection position
- The compartments of functional units are separated by movable metal partitions, which open and close automatically as the drawers are pushed and pulled out, so that they cannot touch the vertical bus bars in the compartments
> Busbar system
- Adopt three-phase four-wire system or three-phase five-wire system
- High quality three-phase tin bus copper bar, high mechanical strength, good heat dissipation
- The flat bus arrangement makes the device have good dynamic and thermal stability, and can withstand 80/176kA short circuit current impact
> Processing and assembly
- Dust-free workshop to ensure insulation
- Assembly workers have been trained for at least 6 months
- The secondary connection is automatic terminal crimping machine to ensure reliable connection
- Use power tools to ensure proper torque for bolting reinforcement
- The copper bus is CNC cutting, punching and bending to ensure the accuracy
- All kinds of experimental tests before delivery to ensure the normal operation of the equipment
Product parameters
Conditions of use
-The altitude above sea level shall not exceed 2000m
- ambient air temperature not higher than +40 ° C, not lower than -5 ° C (average temperature within 24 hours not higher than +35 ° C)
- The humidity of the surrounding air should not exceed 50%. Low temperature allows a large relative temperature (e.g. +20 ° C is 90%). Consideration should be given to the effect of condensation caused by temperature changes
- Inclination with vertical plane is not more than 5°, and the whole group of cabinets is relatively flat, in line with (GBJ232-2) standard
- Requested in no violent vibration and impact, electrical components will not be corroded, no conductive dust place
