[GFL-type power cabinet]

GFL-type power cabinet is to introduce our factory with high technical performance indicators, consistent with IEC439-1, GB7251.1 and other standards, can meet the development needs of the electricity market, and can introduce products to compete with existing power cabinet, it can be used in power plants , petroleum, metallurgy, textile, building and electrical distribution systems and other industries, in large power plants, petrochemical and high degree of automation systems, require a place with computer interface, as the three-phase AC frequency of 50 (60) Hz, rated voltage 380V, rated current 2000A motor under centralized control system.

1, Main technical parameters

1, power cabinet main circuit rated voltage of AC380V;

2, power cabinets auxiliary circuit rated voltage for the exchange of 220V, 380V.

3, power cabinet rated insulation voltage 500V.

4, power cabinet rated at 630A, 1250A, 2000A

5, power cabinet vertical busbar rated current of 630A.

6, power cabinets rated short time withstand current (1S): the level of the main bus 30KA, 30KA vertical support bus

Second, the structural characteristics

GFL Series AC Power Distribution Cabinet is interval structure, which consists of shaped steel and steel sheet bending assembled by screw connection, the cabinet by the functional unit compartment, the level of bus room, cable room and protection bus chambers, their use is divided into functional units into the line unit, feed unit, lighting unit and the control. Here there is a fixed installation of the bus counter and cabinet without power automatic compensation.

(1) shell

Power cabinet enclosure with IP30 protection grade. To prevent objects larger than ∮ 2.5mm close to and touch live parts cabinet moving parts.

(2) cell compartment:

 
Each cabinet is equipped with a number of power unit compartment. With metal partition between the compartments to prevent the unit due to a failure to expand the possibility of an accident, cell compartment and cable compartment with metal or insulation between the partitions, partitions on the ease of cable through the hole there. Cell compartment of the combination of height of 1400mm to the program according to the required circuitry to provide the corresponding functional unit by the withdrawal of Buzhi Yu inadvertently charged body, cell compartment set up ventilation window on the side for cooling and release of short-circuit generated when breaking free gas.

(3) the level of bus room, room and protection bus cable rooms.

Level of bus and power cables in the cabinet room is located above and around. Protection of busbar power cabinet in the following, the level of bus front room with open doors, doors with direct instrumentation. Installed inside the bus level. (Horizontal bus caught in the cabinet of the bus insulation box, the level of insulation installed between the bus and the instrument to prevent inadvertently charged body partitions. Level bus set on top of dust cover room, cable rooms are used to place the function unit leads to the cable, the top and bottom of the hole can be closed cable leads, protection bus equipped with a removable front room door activities, installation and protection of ground zero line can be removed when the bus. zero line installed in the cabinet below insulator on. the rear to protect the ground bus) power cabinet vertical bus compartment installed in the functional unit of insulation behind the cupboard.

(4) functional units in the cabinet position.

Feed, lighting, power control unit in the cabinet with the "work" and "separation," two locations, in the "work" position compartment doors all closed, and the protection level remains IP30.

(5) Interlock Device:

Automatic with manual handle operated rotary switch or fuse type isolator functional unit compartment and automatic switches or isolators with interlock between the door. It ensures that compartment door closed state to the switch closing, or not closing, but only when the switch is in the sub-state gate to open the door. In exceptional circumstances to allow the switch to open the door closing state, but must use a special key chain can only be lifted.
