>> Circuit scheme

◆ main circuit scheme
The main circuit scheme of zgcs cabinet has 32 groups and 118 specifications, excluding the schemes and specifications derived from the change of control and protection of auxiliary circuits. It includes the needs of power generation, power supply and other power users. The rated working current is 5000A, which is suitable for distribution transformers of 2500kVA and below. In addition, capacitor compensation cabinet is designed to meet the needs of power supply and consumption to improve power factor, and reactor cabinet is designed to meet the needs of comprehensive investment.

◆ auxiliary circuit scheme
There are 120 auxiliary circuit schemes in zgcs auxiliary circuit atlas, which is divided into two volumes. There are 63 AC operation schemes in Volume I and Volume II. The auxiliary circuit scheme of DC operation part is mainly used for the low-voltage plant (station) system of power plant substation. It is applicable to the general control mode of low-voltage auxiliary system, working (standby) power incoming line, power feeder and motor feeder of units with capacity of 200MW and below and 300MW and above.

>> Ordering instructions

◆ when ordering, the user shall provide:
◆ main circuit distribution system diagram and layout plan, rated working voltage, rated working current, setting current of protection device and necessary technical parameters.
◆ indicate the specifications of incoming and outgoing cables.
◆ model, specification and quantity of main electrical components in the switch cabinet.
◆ if bus bridge or bus duct is required between switch cabinets or incoming cabinets, specific requirements such as span and height from the ground shall be indicated.
