Switchgear refers to a full set of power distribution tools assembled from primary tools and also second equipment according to a certain circuit strategy. It is utilized to regulate as well as shield circuits and also devices. The structure of the switchgear is approximately similar, generally divided into busbar room, circuit breaker space, additional control space (instrument area), feeder room, each area is normally separated by steel plates.

low-voltage withdrawable switchgear

1. Comprehending of circulation box (cupboard).

GCK, GCS, MNS are low-voltage withdrawable switchgear; GGD, GDH, PGL are low-voltage fixed switchgear; XZW is a comprehensive circulation box; ZBW is a box-type substation; XL, GXL are low-voltage power distribution cabinets and also building site boxes; JXF is an electric control box; PZ20 as well as PZ30 series are terminal lighting distribution boxes; PZ40 as well as XDD( R) are electric meter measurement boxes.

2. The effect of low-voltage power circulation cabinets.

( 1) It is practical to configure the power supply fairly.

( 2) When the line fails, it is advantageous to regulate the range of the fault and it is convenient to swiftly find the fault point as well as remove it in time.

( 3) It is practical to arrange circuit inspection and repair in pieces, without massive power blackout.

( 4) Various protection devices such as merges to prevent brief circuits as well as air buttons to avoid overload can be easily positioned in the power circulation cupboard.

3. The composition of the low-voltage power circulation closet.

( 1) The power circulation closet primarily includes: electrical wiring terminals, various buttons, defense tools (air switches, integrates, and so on), gauging tools (voltmeter, ammeter, cycle meter, etc.), gauging devices (energetic as well as responsive power) table).

( 2) There are many kinds of low-voltage power circulation closets, as well as the components are extremely various. Taking the power closet as an instance, from leading to bottom: knife switch, existing transformer, air switch, as well as branch circuit breakers.

4. The material of each figure of the power distribution closet version.

GGD low-voltage power distribution cupboard: G-- low-voltage power circulation cupboard; G-- set installation and also electrical wiring; D-- power cabinet;.

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

GCS low-voltage power circulation closet: G-- confined switch cupboard; C-- withdrawable type; S-- Senyuan electric system;.

MNS low-voltage power distribution cabinet is a product made in accordance with the transfer technology of Swiss ABB company.

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

GGD is different from the various other 3 in that it is a set kind, while GCK, GCS, as well as MNS are all cabinet kind button closets. Each outlet device of them is independent as well as each circuit will certainly not influence each other.

GCS is a brand-new generation of drawer type switch closet made by Senyuan Company in the mid-90s with reference to ABB's MNS closet type. The primary structure resembles MNS, with the primary bus bar behind. The distinction from MNS is that the drawer module uses a 20mm module (MNS is 25mm); the drawer embraces a press mechanism, which makes the operation easier as well as flexible.

The MNS cupboard can be operated on both sides, as well as a single cupboard can hold 36 loops (with 1/4 drawers) at the majority of, while the GCS can be as much as 22. The product made use of in the MNS cupboard is aluminum-zinc layered, completely set up framework, no post-processing (galvanizing) is required.

The horizontal busbars of MNS and GCS are separated from the front left cabinet device and also the front right cable television electrical outlet compartment with partitions. Their upright busbars are set up in flame-retardant plastic functional boards to be extra dependable. The difference is that GCS can just have 1/2 cabinet at the very least, MNS has 1/4 cabinet, MNS drawer has an additional interlocking system, and also GCS just has the button itself.
