4. Both indoor and outdoor.
Second, the model meaning
1, 304 stainless steel material, through cutting, milling, cast welding process, such as, beautiful appearance, strong corrosion prevention;
2, built-in CN65, NC100H high marks broken small circuit breaker, contactor, thermal relay, button and the light components, can be used as a lighting, power motor control purposes;
3, with overload, short circuit protection function;
4, module structure, all kinds of circuit can use free assembly;
5, can be tailor-made according to user requirements, such as adding electrophoresis protector, ammeter, voltmeter, etc.;
6, steel pipe or cable wiring.
Three, product features
1. This product is a flameproof, separating detonation type main cavity and XianQiang, USES the high quality SS304 stainless steel plate bending forming, welding has good appearance, corrosion resistance, antistatic impact resistance and other excellent properties. Built-in circuit breaker and light components.
2. The cover is equipped with the special operating mechanism, which can realize fully enclosed operation. Products under the bad environment also can normal operation.
3. All fasteners are strong resistance to corrosion of 304 stainless steel fasteners.
4. Steel tube wiring or cable wiring.
5. According to user requirements special.
Four, the main parameter
The anti-corrosion class rated voltage (V) rated current (A) the explosion-proof marks because protection grade
10-100 a ExdIIBT4 WF2 220/380
DIPA20 TA, T4 4, 6, 8, 10, 12 IP54 or IP65
Five, the order information
Users in order to indicate the back of the distribution box, the number of loop current and circuit breaker, if take master switch to indicate the main switch and the number of current, and into the outlet direction, quantity and size. If lighting, mixed, such as dynamic and leakage, a schematic diagram may be required.
Six changes, because the product type is more, install the appearance, size and forms need to be assembled with the customer after the disclosure shall be separately provided.
classification
Classification according to the structural characteristics and USES:
(1) fixed surface type switchgear, often called switch board or distribution panel. It is a kind of panel block open switch cabinet, positive has protective effect, and on the back side can still hit a live part, protection grade is low, can only be used for low power supply continuity and reliability requirements of industrial and mining enterprises, for substation room centralized power supply.
(2) protected (closed) switchgear, refers to in addition to the mounting surface, all the other side are closed up and a low pressure switch cabinet. This switch, protection and monitoring control cabinet and other electrical components, are installed in a closed shell made of steel or insulating materials, reliable wall or installed from the wall. Ark can not isolation measures, between each circuit can be used earthing metal plate or insulation board in isolation. Usually has a mechanical interlocking door and the main switch operation. Another protected type switchgear (i.e., the console), on the front panel is equipped with electric equipment such as control, measurement, signal. Protection type switchgear mainly use work art field distribution equipment.
(3) the draw-out type switchgear cabinet. This kind of switch cabinet adopts steel plate closed case, into the wire loop electrical components installed in a can be pulled out of the drawer, can constitute a complete functions to one kind of power supply unit. Functional units and between bus or cable, with the function of the grounding of metal or plastic plate is separated, forming generatrix, functional unit and cable three regions. Also have isolation measures between each function unit. Draw-out type switchgear has higher reliability, security and compatibility, is more advanced than the switch cabinet, the current production of switchgear, majority is draw-out type switchgear cabinet. They apply to requirements of power supply reliability higher industrial and mining enterprises, high-rise buildings, as a central control of the distribution center.
(4) the power and lighting distribution control box. For the enclosed vertical installation. Due to the use of different occasions, the shell protection grade Is also different. They mainly as industrial and mining enterprises in the production of the power distribution device.
use
Manageable, when circuit malfunction happened, it is helpful for maintenance.
Distribution box and distribution cabinets, panel and distribution with, switch, instrument equipment such as concentrated installation of complete sets of equipment.
The commonly used two kinds of distribution box with wooden and iron plate system, now where electricity consumption is quite large, so more or the use of stainless steel.
Distribution box USES: of course, is convenient to stop, sending, have the effect of measurement and judgment stops, either.
