Switchgear describes a full set of power circulation tools constructed from main equipment and additional equipment according to a specific circuit plan. It is made use of to control and shield circuits as well as tools. The framework of the switchgear is about similar, generally split into busbar area, breaker space, secondary control room (tool area), feeder room, each room is generally divided by steel plates.

low-voltage withdrawable switchgear

1. Recognizing of circulation box (cabinet).

GCK, GCS, MNS are low-voltage withdrawable switchgear; GGD, GDH, PGL are low-voltage dealt with switchgear; XZW is a comprehensive circulation box; ZBW is a box-type substation; XL, GXL are low-voltage power circulation closets as well as building website boxes; JXF is an electric control box; PZ20 and PZ30 collection are incurable illumination distribution boxes; PZ40 and also XDD( R) are electric meter dimension boxes.

2. The result of low-voltage power circulation cupboards.

( 1) It is convenient to configure the power supply reasonably.

( 2) When the line falls short, it is valuable to regulate the range of the fault and also it is hassle-free to rapidly find the mistake point and remove it in time.

( 3) It is convenient to set up circuit maintenance in items, without large power outage.

( 4) Various defense devices such as fuses to avoid short circuits as well as air switches to prevent overload can be easily positioned in the power distribution cupboard.

3. The make-up of the low-voltage power circulation cabinet.

( 1) The power circulation closet mainly includes: wiring terminals, numerous buttons, defense tools (air buttons, fuses, etc.), measuring tools (voltmeter, ammeter, cycle meter, etc.), measuring tools (active and reactive power) table).

( 2) There are numerous kinds of low-voltage power distribution cabinets, and also the components are very different. Taking the power cupboard as an instance, from leading to pickling line manufacturer base: blade switch, current transformer, air button, and branch circuit breakers.

TControl power circulation cupboard.

4. The material of each number of the power circulation closet version.

GGD low-voltage power circulation cabinet: G-- low-voltage power circulation cabinet; G-- fixed installation and electrical wiring; D-- power closet;.

GCK low-voltage power distribution closet: G-- cupboard structure; C-- withdrawable kind; K-- control center;.

GCS low-voltage power circulation closet: G-- enclosed button closet; C-- withdrawable kind; S-- Senyuan electrical system;.

MNS low-voltage power circulation cupboard is an item manufactured according to the transfer innovation of Swiss ABB firm.

5. The distinction in between GGD, GCS, GCK, MNS power circulation cabinet.

GGD is different from the various other 3 in that it is a set type, while GCK, GCS, as well as MNS are all cabinet type switch cupboards. Each outlet unit of them is independent as well as each circuit will not impact each other.

GCS is a brand-new generation of cabinet type switch closet created by Senyuan Company in the mid-90s with reference to ABB's MNS cabinet type. The major structure resembles MNS, with the primary bus bar behind. The distinction from MNS is that the cabinet module uses a 20mm component (MNS is 25mm); the cabinet adopts a press device, that makes the operation easier as well as adaptable.

The MNS cabinet can be operated on both sides, and also a single cupboard can hold 36 loopholes (with 1/4 cabinets) at many, while the GCS can be up to 22. The material made use of in the MNS cupboard is aluminum-zinc plated, totally constructed framework, no post-processing (galvanizing) is required.

The horizontal busbars of MNS and GCS are divided from the front left cabinet device and also the front right cable electrical outlet compartment with dividers. Their upright busbars are set up in flame-retardant plastic useful boards to be more reputable. The difference is that GCS can just have 1/2 drawer at the very least, MNS has 1/4 cabinet, MNS cabinet has one more interlocking device, and GCS only has the button itself.
