XL-21

The power cabinet refers to a combination of electrical control cabinets that provide power for the normal operation of the entire machine, including contactors, frequency converters,high-voltage cabinets, transformers, and so on.

Is iad seo a leanas a fheidhmeanna:

Supply power to electrical equipment (provide power for the equipment);

Start and stop the operation of electrical equipment (with start and stop buttons);

Detect the operation of the equipment (set signal indicator lights, with ammeters and voltmeters);

Protect electrical equipment (circuit breakers).The power cabinet is the power distribution cabinet,which is specifically used to provide power supply and control for power equipment (generally referring to motors).

The XL-21 series low-voltage power distribution cabinets are widely suitable for industrial and civil buildings, and are used for power distribution and lighting distribution in a three-phase four-wire power system with an alternating current frequency of 50HZ,60HZ and a voltage of 1kV and below.

At the same time,it is suitable for manufacturing various motor staring cabinets, including full-voltage direct starting cabinets, fully digital control soft starting cabinets,autotransformer step-down starting cabinets,star-delta starting cabinets, multi-speed motor starting cabinets, etc.

There are dozens of primary circuit scheme numbers or derived scheme numbers for selection,with a wide range of applications.

This product is an indoor enclosed distribution box.

The box body is bent and welded with thin steel plates, and there is a single left-opening door on the front.Measuring instruments such as voltmeters and ammeters, as well as operating electrical appliances and signal electrical appliances, are installed on the door.

It is a power distribution device with a simple structure, reliable operation and low cost.

Ní bheidh teocht an aeir chomhthimpeallaigh níos airde ná +40 ℃ agus ní ísle ná -5 ℃, agus ní bheidh an teocht an meán laistigh de 24 uair an chloig níos airde ná +35 ℃. Nuair a sháraítear na teorainneacha sin, díreofar an acmhainn chun oibriú de réir na staide iarbhír.

Tá sé le húsáid faoi dhíon, agus ní bheidh airde an loctin suiteála níos mó ná 2000m.

Ní rachaidh taiseachas coibhneasta an aeir chomhthimpeallaigh thar 50% nuair is é +40 ℃ an teocht uasta. Ag teochtaí níos ísle, ceadaítear taiseachas coibhneasta níos airde. Mar shampla, tá sé 90% ag +20 ° ℃. Ba cheart tionchar comhdhlúthúcháin ó am go chéile de bharr athruithe teochta a chur san áireamh.

Nuair a bheidh an gléas suiteáilte, ní bheidh an claonadh ón eitleán ingearach níos mó ná 5 °, agus beidh an grúpa iomlán de na sraitheanna comh-aireachta sách cothrom. Déanfar an gléas a shuiteáil in áit gan creathadh agus tionchar mór, agus i gcás nach mbeidh na comhpháirteanna leictreacha faoi réir creimeadh míchuí.
