Do you know the difference between low-voltage switchboard - switchboard and low-voltage switchboard?

1. Size difference. The specifications of a low-voltage PDC may not be included in the box.

2. The parts are different. The distribution box, only the instrument panel is installed, has a football fan motor pump, and must have many characteristics of impedance type AC contactor type automotive relays of this kind. Most of the chassis isolation switches and isolation switches made from the bottom pressure cabinet structure mold.

3, the raw materials in the line are different. Multi-transmission line distribution box. Bottom pressure complete equipment switchgear, copper key centralized in the main line task.

4. The basic principles are different. According to the patent application right in the closed or semi-closed server cabinet or metal mesh, the power distribution room equipment assembly communication AC low-voltage distribution cabinet. Cable distribution box. In all normal practical operation, the power supply circuit can be manually or fully automatic according to the transfer switch. Is a detailed switchgear and control system, the main switch power management center and delivery machine equipment.

5, the selection is different.

Distribution boxes are used to operate the above main power plug and electrical equipment, supervision, accurate measurement and maintenance. Generally installed in the distribution power station, high and low voltage distribution room. Common in power generation, distribution equipment, transformer. It is suitable for power station, crude oil, chemical plant, metallurgical industry, textile, multi-storey building and other manufacturing industries, as the transmission, division and output power conversion

Low voltage switch.

6. Features. The distribution box has small specifications, simple installation, unique technology, fixed parts, and distinctive features, which will not be limited by indoor space, more common program operation, reliable operation, high efficiency of indoor space, and small specifications and hazards to the natural environment. With the design scheme is effective, the general structure of soft parts, the standard control module, and the safety factor is high

Low-voltage distribution cabinet GGD series product models, GCS series products, MNS series products, MCS series products, detailed as follows:

First, GGD series products

1. GGD cabinet takes heat removal into account. A different number of cooling slots are provided above and below the housing, and when the thermal components are heated up, the housing is discharged from the top slot, and the bottom slot electronic counter is continuously added according to the strong cold air, because of the natural tightness of the housing and the ventilation duct generated under it for cooling purposes.

2, the case cover can be removed when necessary in order to facilitate the installation and adjustment of the main system bus industry, with the cabinet top ring lifting and transporting the four corners.

3, the waterproof level of the cabinet door IP30, customers can IP20-IP40 in accordance with environmental protection regulations to carry out selection.

Second, GCS series products low-voltage distribution cabinet based on what.

1, as shown, the frame type opening 8MF application steel, installation displacement coefficient E=20 mm and installation hole Φ9, 3mm 100 mm, to promote the flexibility of the architecture components on the main structure.

2. Each function of the high-voltage switchgear room separated from each compartment is divided into the function module room, the busbar trough room and the cable room. Individual operations in each room.

3. In the structure of the leveling system bus installation box, in order to improve the working ability of the anti-power engineering system bus, the main circuit short circuit has the basic countermeasures of high toughness working ability.

4, drawer height width ratio 160mm strain rate. Drawer conversion only changes in aspect ratio specifications, width, depth specifications do not change. Drawer also function module with excellent compatibility mode.

3, MNS series products

1. The frame structure of the MNS low-voltage switching machine equipment is assembled from the base frame of C-produced steel. All the prefabricated components are constructed according to the hot-galvanized cabinet, which are connected into approximately hexagonal 8 and 8 cabinets by the rigidity self-tapping locking screws or screws, together with the program flow matching the change at the door, the baffle, the mounting support frame and the action module of the system bus component components, etc., into a detailed power switch. The internal specifications of the high voltage switch cabinet, the specifications of the parts, and the specifications of the above compartment are based on the transformation of the strain rate (E=25mm).

2, each modular design of the server cabinet MNS type low-voltage switch is divided into three rooms, that is, the level bus compartment (in the rear server cabinet), the drawer compartment (in the front of the housing), the lower cable compartment (or in the right front cabinet cabinet). The above chambers and to avoid the common faults of electric arcs or busway switches due to short circuit faults have high-strength steel plates or multifunctional pvc wires on the board to separate the metal pieces of the vents in the middle of the bottom drawer from each other, reasonable intermediate and other safety accidents caused by.

3, the design scheme MNS type low voltage switch can consider a variety of channels and entrances planning scheme provisions: under the progress, development, the bottom end of the bottom out of the content.

Four, MCS series products

. 1, the selection of C-type switch cabinet opening assembly steel, unified appearance of high precision, good interchange drawer infrastructure (or input 8MF).

2, only the total width of 600mmMCC cabinet, the use of indoor space, can accommodate a large number of function modules, saving land

3, according to different customer regulations, a variety of types of shell components equipped with power switches, stronger to ensure the high reliability of the product. The low-voltage PDC model specifications indicate.

4, jack machine equipment can be automated technology, intelligent control module can also be installed in the high voltage switch cabinet to complete remote control communication, monitoring, remote operation and other three remote control functions.

Low voltage distribution cabinet:

1, low-voltage switch machine equipment and control system is generally known as low-voltage switch, also known as low-voltage distribution cabinet, it refers to AC and DC operating voltage less than 1000V working voltage electrical equipment.

2, the basic construction of our smart energy sales market, the completion of infrastructure construction, project investment and new energy technology production and manufacturing industry development planning of low-voltage distribution cabinet has been maintained at a high speed.

3, data monitoring display information, in 2010, the market sales of low-voltage distribution cabinets in all Chinese markets 10, 633 billion RMB, a year-on-year growth rate of 11, 2%; In 2011, the low-voltage distribution cabinet market sales of 11, 96 billion RMB, a year-on-year growth rate of 12, 5% of the overall sales market.

4, for everyone's low-voltage distribution cabinet natural environment great market demand, the market competition in the manufacturing industry will increase, dealers show a new generation of low-voltage machinery and equipment and system software solutions to promote the first opportunity in the future market demand, its products only have the characteristics of the future market competition, to obtain certain advantages, Therefore, grasp the high ground of the fourth generation of low-voltage electrical products.
