AC Low Voltage Withdrawble Distribution Switchgear Low Voltage Switchgear

Low Voltage Industrial Electrical Switchgear Spray Paint Surface Treatment

General:
Switchgear can be composed of double back-to-back arrangement. hence the security and flexibility of the switchgear improves, and the area reduces.
Shell
The shell of the switchgear chooses imported aluminium zinc steel plate, processes through CNC machine and adopts multiple folding processes. The whole cabinet is featured with high precision and strong resistance to corrosion and oxidation. As a result of multiple folding process, the cabinet is lighter, stronger and neater than other similar cabinet. The cabinet uses packaged structure and connects each part with pull rivet nuts and high strength bolts. Short production cycle, versatile components and parts and less area are easy to organize production.
Handcart
The framework of the handcart is made of thin steel plate after CNC machine tool processing for assembling. Handcart and cabinet match up with high precision and safe, reliable and flexible mechanical interlocking. Handcarts are divided into different kinds by usage, such as circuit breaker handcart, voltage transformer handcart, metering handcart, isolation handcart, etc. and handcarts with same specification can be freely interchangeable. Handcart in the cabinet has disconnect test position and work location with positioning device respectively to ensure reliable interlocking. Each handcart adopts screw rod to push in and pull out, hence such convenient and flexible operation is suitable for the personnel on duty. When the handcart needs to be removed from the cabinet, the personnel just uses a special transport vehicle to pull it out. It is very convenient for all kinds of inspection and maintenance.
When the handcart is pushed into the circuit breaker compartment by the transport vehicle, the circuit breaker is in the disconnections position, and the indicator lights of the cabinet show its location. Only after the handcart completely locked. the screw structure can be derived and the handcart can be pushed into working position. When the handcart arrives at working position and the sudden increase of the pushing handle operating force stays motionless, its corresponding position indicator will show its location. The mechanical interlock of the handcart guarantees the circuit breaker to close only in working test position. And the handcart can be removed only when the circuit breaker is separate.
Compartment
The main electric components of the switchgear have their own independent compartment. such as circuit breaker handcart compartment, busbar compartment, able compartment and relay instruments compartment. The protection grade of each compartment is P2X. In addition to relay instruments compartment, the other three compartments all have pressure relief channel respectively. Due to the adoption of mid-set type, the space of the cable compartment greatly increases, so the device can receive multi-channel cables.


Protection grade of cabinet: IP30. User can choose within IP20~IP40 according to environmental requirements.


Conditions for normal operating environment:

1. Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h.
2. Install and use indoors. Altitude above sea level for operation site should not exceed 2000M.
3. Relative humidity should not exceed 50% at max temperature +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.
4. Installation gradient not exceed 5.
5. Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components.
6. Any specific requirement, consult with manufactory.
