Factors affecting the design changes of explosion-proof distribution boxes

There are many types of distribution boxes in domestic power supply and distribution systems, and their cabinet structure technical parameters are different. Under the influence of the following factors, the well-designed drawings often need to be modified or even redesigned. This not only affects the construction plan of the power supply and distribution system, but also brings about the production of the distribution box to the explosion-proof distribution box manufacturers on time and quality. Certain problems.

The factors that affect the design changes have been designed as follows:

1. The distribution box manufacturers recommend to the user their own products that may not be suitable for the user.

2. The Design Institute does not know much about some of the newly introduced boxes. It is only designed according to the user's requirements.

3. Users do not fully understand their own needs. When choosing a box, they cannot choose according to their needs.

In order to solve the above problems and satisfy the user's need to select a specific model of the distribution box more accurately, the following analyses the characteristics of low-voltage distribution boxes commonly used in domestic power supply and distribution systems.

The explosion-proof power distribution boxes commonly used in domestic power supply and distribution systems can be roughly divided into two types. One is the Low-voltage explosion-proof distribution box developed by International Electric Co., Ltd. (hereinafter referred to as imported low-voltage distribution box). ), Such products can only be produced and sold by International Electric Co., Ltd. or authorized domestic well-known distribution box manufacturers. They represent the PrismaP, BLOKSET, OKKEN low-voltage distribution boxes of the French Schneider Electric Co., Ltd., and Siemens AG of Germany. Sivcon low-voltage distribution box, Germany Admiralty - Mulide Modan6000 low-voltage distribution box, Switzerland ABB Electric Co., Ltd. MNS3 low-voltage distribution boxes;

The other is a low-voltage explosion-proof pressure distribution box (hereinafter referred to as a domestic low-voltage distribution box) that is independently developed or copied by a domestic explosion-proof distribution box manufacturer and passed a certificate for explosion-proof certification. The representative of such products is a GGD AC. Low-voltage distribution box, GCK low-voltage withdrawable switch box, GCS low-voltage withdrawable switch box, MNS low-voltage withdrawable switch box, GCL low-voltage withdrawable switch box. The main characteristic of the imported low voltage distribution box is that the specific structure of the distribution box produced by the International Electric Co., Ltd. or its authorized manufacturer can be kept consistent. The main electrical components installed in the distribution box are compatible with those of the International Electric Co., Ltd. The brand remains the same and there are imported brands on the obvious position of the distribution box.
