What is switchgear accessories?

The complete control cabinet is a kind of electrical equipment. The external line leads first into the main control switch in the cabinet and then into the lower control switch, and each branch is adjusted according to its needs. Such as instrumentation, automatic control, motor magnet switches, various AC shooters, etc., Some also have a complete set of control cabinets for high and low voltage rooms and high voltage collector rails, such as power plants, and some are equipped with a low voltage protection for main equipment. Weekly load drop. The switching device includes all switchgear accessories.

What are the technological characteristics of switchgear accessories?

①The switchgear accessories have good rigidity and will not be affected by deformation of the workpiece;

②The external dimension of switchgear accessories is slightly larger than the nominal size of the workpiece, which can offset the effect of shrinkage after welding;

③Smooth, simple and convenient operation, minimize the rotatable mechanism to avoid jamming;

④switchgear accessories In order to prevent welding corrosion and facilitate the maintenance and adjustment, it is necessary to select the support of the workpiece, and to add anti-weld corrosion pads to the support. The post-welding deformation of the workpiece is caused by the stress caused by the expansion of heated molecules at the weld during welding and the micro-displacement caused by extrusion, which cannot be reset after cooling.

What are the advantages of switchgear accessories?

The advantages of switchgear accessories are that they are suitable for pre-plating the workpiece, easy to change and adjust, easy to beautify, and the parts can be standardized design, and can be pre-production stocked, and the frame size error is small. The disadvantage is that it is not as strong as welding, requires high precision of parts and components, and the processing cost is relatively increased. Fasteners are generally standard parts, and their types mainly include conventional screws, nuts and rivets, pull rivets, as well as pre-tightened and fine-adjustable clamp nuts and pre-tightened tension nuts, as well as self-tapping screws. There are also special fastening screws (for example, most low-voltage cabinets imported from abroad use special fastening screws).

What are the structural characteristics of switchgear accessories?

1. The mechanical interlocking mechanism of various drawers of various sizes meets the standard requirements, with three obvious positions of connection, test and separation, which are safe and reliable.

2. switchgear accessories adopt standard module design: they can be composed of standard units such as protection, operation, conversion, control, adjustment, measurement, indication, etc., and can be assembled as required.

3. The switchgear accessories use high-strength flame-retardant engineering plastics, which effectively strengthens the protection and safety performance.

4. Versatility, high degree of standardization, and convenient assembly. Have reliable quality assurance.

5. The cabinet body of switchgear accessories can be selected according to the different requirements of the working environment.

6. The equipment protection continuity and reliability of switchgear accessories.

Zhejiang Zhegui Electric Co., Ltd maintains close relationships with customers in switchgear accessory industry, and is committed to strengthening production and operation, improving quality and safety.
