The distribution box is a kind of electrical equipment with the advantages of small size, easy installation, special technical performance, fixed location, unique configuration function, not restricted by the site, wide range of uses, stable and reliable operation, high space utilization, small footprint and good environmental protection effect. Features. It is the control centre that directs the reasonable distribution of electrical energy among the components in the power supply line, is the control link that reliably accepts power supply from the upper level and correctly sends out load electrical energy, and is the key to obtaining satisfactory power supply quality for users. Improving the operational reliability of the distribution box is the goal of creating quality projects.
When the distribution box is working normally, it can manually or automatically disconnect the circuit and also connect the circuit. And when there is an abnormality or fault in the circuit, it can protect the appliance, cut off the circuit and have an early warning function.
In addition, it can measure some parameters of operation in the apparatus and adjust some parameters. So that it can give an indication or send a specific signal during normal operation. It is generally used in power generation, substations and distribution.
There are many types of distribution cabinets in the domestic power supply and distribution system, and their cabinet structures and technical parameters are different. Under the influence of the following factors, the design drawings often need to be modified or even redesigned, which not only affects the construction program of the power supply and distribution system, but also gives the power distribution cabinet manufacturers to complete the production of distribution cabinets on time and in quality to a certain extent It brings troubles. The following factors affect the change of design drawings.
1. the manufacturer of the distribution box advises the user that the product they produce may not be suitable for the user's use
2. The design institute did not have a good understanding of some of the newly introduced cabinet types and only designed according to the user's requirements.
3. Users do not fully understand their needs and are not able to choose the type of cabinet according to their needs.
Distribution boxes are generally used in households, while distribution cabinets are mostly used for centralised power supply, such as for industrial and building electricity. Distribution boxes and cabinets are complete sets of equipment, distribution boxes are low voltage sets of equipment, distribution cabinets have high and low voltage.
