The low-voltage switchgear can ensure that all electrical components are religiously fixed in the determined positions within the cabinet. Ex aspectu cabineti editor Guangdong Ziguang observavit quoniam cabinet in forma cubiculum est, sicut typus schermi, typus cisternae, etc., et sunt corpora angularum, sicut tabulae. Hoc typus cabineti et unum lineam et optiones ordinem habet. In order to ensure the shape and size of the low-voltage switchgear, a step-by-step combination of various components is often adopted. Generally, two pieces or left and right sides are formed first, and then the cabinet is formed, or the external requirements are met first, and then the internal support parts of the cabinet are connected in sequence. The length of the parts that make up the edges of the cabinet must be correct (with negative tolerances) in order to ensure all geometric dimensions and overall shape requirements. Editor Guangdong Ziguang credit quia pro duobus lateribus cabineti oportet considere ordinem et non esse protrusionem in medio.
Ex perspektiva installationis, minima voltage switchgear non debet sincere super superficiem subter. In the arrangement and installation, a flat foundation is a prerequisite, but there are certain errors in the dryness and the cabinet itself. In the arrangement, it is necessary to try to offset the lateral differences as much as possible, rather than causing the accumulation of differences, because the accumulation of differences will cause deformation of the cabinet, affect the busbar connection, cause component installation misalignment, stress concentration, and even affect the service life of electrical appliances. Pro hoc, cum arrangisset, consilium est altissimum punctum fundamenti ut referentiam punctum installation is, et postea graduale expandere dispositionem. sub conditionibus idealis et predictabilis suscitationis fundamenti, dispositione etiam ab medio usque ad utraque latere ad pariter partem pariter distribuere faciem accumulationis.
To facilitate adjustment and offset tolerance accumulation, the width tolerance of the cabinet is set to negative values. Post congregationem diversorum componentum cabineti conpletum est, redactum est quam necessarium est, ut conformetur universae part is necessitatibus dimensionalis. When manufacturing fixed or large batch cabinets, full consideration should be given to the use of fixtures and jigs to ensure the correct and unified structure. The reference surface of the fixture should be taken from the bottom, and the arrangement of each positioning block in the fixture should be based on the convenience of work removal. For the external doors of the cabinet, which are easily affected by transportation and installation, they are generally adjusted uniformly during installation.
