Iii.Model and meaning
Iv.Main features:
The product is composed of two major parts of the cabinet and the handcart.The front of the cabinet,between the cabinets and the terminals on both sides of the cabinet are protected by steel plate door or metal sealing plate.
The electrified body of the product is mainly air insulation,the insulation distance between the electrified body and the phase is not less than 300mm,only the individual parts of the cabinet,the phase spacing is not enough to set the insulation interval;
The bottom of the handcart room is the handcart track,and a positioning mechanism board is welded on the inside of the track for the handcart to push and pull out.A grounding contact piece is welded on the outside of the track(the handcart touches the ground through this contact piece through the cabinet).
In order to ensure the correctness of operation procedures,this type of switchgear is equipped with mechanical or electrical interlocks;
According to the purpose,the handcart is divided into six categories:circuit breaker,three-phase and single-phase voltage transformer,lightning arrester,isolation and transformer used.All kinds of handcarts are equipped with identification devices to ensure that the same type of handcarts can be exchanged,while different types of handcarts cannot be exchanged.
