Specifications

Technical force is abundant, detection equipment, and has many national patents.

Mostly purpose
GGD communication equipment is suitable for low voltage distribution switch power substation, power users as mining enterprises etc, rated voltage isolator ac 380V rated current 3150A to the distribution system in power distribution equipment, lighting and the energy conversion, distribution and control. The products, high abilities which are rated current of 50KA short. Line, flexible, practical, easy combination of novel structure, etc. This product is the representative assembly type fixed panel switchgear.
The product conforms to the low voltage switchgear equipment GB7251 IEC60439, the low voltage switchgear equipment and control equipment etc.

Technic Parameter
1, the main technical parameters, see table 1
2 and auxiliary circuit
Auxiliary circuit design scheme and power utilization points scheme in two parts.
Line 3, mistress
In 1500A and rated current below the single copper platoon bus. More than 1500A rated current when using double copper platoon bus. The surface generatrix of overlapped by honing tin process.
1) level busbar selection (table 2)
2) neutral earthing selection bus (see table 3)
3) electrical components
A, GGD ark mainly adopts already can batch production of domestic electrical components. As such, DZ20, DWI5 guijia breaker can also choose must, AE, M, F, plastic shell breaker selection, and other advanced CML of electrical components.
B, HDI3BX and HSI3BX type operating knife switch is designed for unique structure and design of the special components, it has changed the organization mode of operation, retain the old products, it is a kind of utility of electrical components.
C, such as design department, choose according to user's needs more excellent performance, technology more advanced new electrical components, because install ark, GGD flexible for updating the electrical components manufacturing and installation of caused difficulties.
D, in order to further enhance the ability of dynamic stability, the circuit of the ark in GGD busbar type combined-type generatrix ZMJ clips and support. By high intensity, busbar clip high-fire-retardant PPO composite thermal insulation of forming, high strength, good self-extinguishing RTV silicone compound, unique structure, just adjust block can be easily combination between blocks of single or double generatrix of busbar folder. Insulation support is sleeve mould structure, low cost, high strength, solve the old product creep age distance of insufficient.

Construction Features
GCK GCL, basic guijia for combination fabricated structure, the whole structure and guijia, pensu processing through galvanized through screw fastening interconnect into basic guijia, again plus door, according to the need, partition, drawer, mounting bracket busbar and electrical components and parts, assemble a complete control center, the ark cabinet has the following characteristics: structure,
1 'guijia
Guijia using C payments, the local welded parts and special guijia matching parts by our company offers, ensure the precision and quality of cabinet put oneself in another's position.
1) parts of the size, size, hole spacing device implements modular (module with E = mm),
2) internal structure USES galvanizes processing
3) to dismantle can cover cabinet put oneself in another's position, remove above can be very convenient installation, the top level of the corners of busbar with rings, used for lifting and shipment.
4) outside the phosphorus processing and using epoxy powder coating.
5) guijia into busbar room, functional unit room, cable room three separate from each other, can prevent accidents interval and convenient maintenance. Spread charged
