Iii.Model meaning
4.Structural features
Insulation methods such as thermal shrinkage and epoxy coating are adopted to optimize the shape of electrodes,making the cabinet compact in structure and small in floor area.
The cabinet body structure is assembled by aluminum and zinc plate,and the circuit breaker is floor structure of handcart.
It is equipped with new type of composite insulated vacuum circuit breaker or sulfur hexafluoride circuit breaker,and has the characteristics of good interchangeability and easy replacement.
A screw nut driving mechanism is installed in the frame of the handcart,which can easily move the handcart and prevent damage to the driving structure due to wrong operation.
All operations can be carried out when the cabinet door is closed.
The interlocks between the main switch,the circuit breaker handcart,the grounding switch and the cabinet door all adopt the mandatory mechanism locking mode,which satisfies the"five prevention"function and is safe and reliable.
The functional compartments of the switch cabinet are separated by metal partitions,and there are independent pressure relief channels for the circuit breaker room,bus room and cable room.
Switch cabinets have strong structural adaptability,diverse schemes,and can meet the requirements of different users;
There is enough space in the cable room to connect multiple cables.
The protection grade of the shell is IP3X.When the door of the handcart room is open,the protection grade is IP2X.
