● Structure: GCK minimum drawer unit 1 module, a total of 9 layers, that is, a total of 9 units.
When ordering, users should provide the following information:
● Full model of the product (including the main circuit scheme number and auxiliary circuit scheme number);
● Distribution cabinet surface paint film color;
● Main circuit system combination sequence diagram (permutation diagram and single line diagram);
● Distribution cabinet arrangement diagram auxiliary circuit electrical schematic diagram;
● List of cabinet components;
● Other special requirements inconsistent with the normal use conditions of the product.
Structural characteristics of
● The whole cabinet adopts assembling type combination structure, modular hole installation, parts and components of strong versatility, good applicability, high degree of standardization.
● There is a mechanical interlock between the door of the MCC cabinet drawer compartment and the operating handle of the circuit breaker or disconnecting switch. The door can be opened only when the handle is in the disconnecting position.
● Receiving switch, contact switch and DRAWER of MCC cabinet have three positions: on position, test position, off position.
Switchgear USES modular design, the cabinet put oneself in another's position is divided into three zones, the top for bus bar area, the front for the electrical area, the rear area for the cable into the line, each zone are the main plate is separated in order to ensure the normal operation of line, effectively prevent the fault, after the electrical components extraction tank outside, inside a charged body is not exposed, for users to use more reliable.
● According to the characteristics of switch cabinet can be divided into electric cabinet, feeder cabinet, capacitor compensation cabinet
● The drawers of the same functional unit can be exchanged. Once the failure occurs, the failure unit can be pulled out and the spare drawer can be inserted, which greatly shortens the failure time and improves the reliability of the equipment.
● Switch cabinet can be designed into fixed and drawer cabinet mixed type, also can be drawer type, both retain the fixed cabinet simple, practical, inexpensive, and has the advantages of small size, strong function, easy to replace.
● In order to ensure the safety of operation procedures and maintenance personnel, the switch cabinet is set with mechanical interlocking mechanism, drawer unit door, the main switch is set with mechanical interlocking mechanism, so that its use is more reliable.
● The PE line of the switch cabinet is under the back of the switch cabinet, and the PE line is connected with the cabinet frame, which not only makes the outgoing cable connection more convenient, but also makes the grounding more reliable.
