A combined installation method of a sealed distribution box

Abstract

The invention belongs to the technical field of power distribution, relates to an installation method for combined sealed power distribution boxes, and specifically relates to an installation method for combining basic power distribution cases of a variety of shapes into any shape. The installation method mainly comprises six steps: environment investigation, selection of basic power distribution cases, power distribution box assembling, power distribution box fixing, cable installing, and pumping-packaging. Basic power distribution cases of four different shapes are combined and assembled into a combined sealed power distribution box applying to all kinds of working shapes through side connection holes, bottom shell spiral holes and connection bolt pin devices arranged in the basic power distribution cases. The method has the advantages of simple assembly process design, flexible assembly concept, low assembly cost, easy use and installation, and high safety. A power distribution box installed by the method can be kept in a relatively stable working environment for a long time.

Description

Technical field: [0001] The invention belongs to the technical field of power distribution, and relates to an installation method of a combined sealed power distribution box, in particular to an assembly method for combining basic power distribution boxes with various shapes into arbitrary shapes. Holes, bottom shell screw holes and connecting pin devices realize the assembly of distribution boxes of various shapes. Background technique: [0002] The distribution box or meter box is a device used to install devices such as meters and switches. It is very common in daily life or various construction occasions, and is an indispensable equipment in the power supply department. First of all, people’s daily electricity consumption mostly adopts the one-meter-one-household system. In order to strengthen management, the power department usually uses multi-meter meter boxes to centrally install users’ electricity meters. Although the management is convenient, during the installatio...

Problems solved by technology

Although the management is convenient, during the installation process, the power supply switch and the electric meter are installed in one box, which is easy to make mistakes when wiring, and it is not easy to find the faulty electric meter during maintenance; secondly, the shape of the integral power distribution box is large and It cannot be changed, and it cannot be adjusted according to the spatial structure of the working environment, which will easily lead to the inability to make full use of the space, and it may also easily lead to the inability to install in a small space; thirdly, in some outdoor operations, the number of electric meters usually required is small, and the overall Type electric meter box is extremely inconvenient in carrying, installing, also can't make the best use of everything simultaneously, causes waste; There are still many problems unresolved in this kind of collective electric meter box assembly

One is that each meter box of this collective meter box assembly is a cuboid of the same specification, and it is impossible to assemble a distribution box structure with more structural shapes in different work spaces, and the ability to cope with the working environment is poor; The reason is that the box body of the meter box does not have airtightness, the inside of the box body of the meter is easy to enter moisture, and it is attached to the inside of the box cover, which makes it difficult to read. At the same time, the humid box environment will seriously affect the service life of the meter
