Teaching work instrument of distribution network standardized substation

Abstract

The invention discloses a teaching work instrument of a distribution network standardized substation. The teaching work instrument includes a base, electric poles, a transformer and distribution box cross arm, an arrestor cross arm, a high voltage fuse cross arm, a lead cross arm, a low voltage line cross arm, a high voltage line cross arm, a transformer, a low voltage distribution box, and grounding down leads, wherein the electric poles are vertically fixed to the base, the transformer and distribution box cross arm, the arrestor cross arm, the high voltage fuse cross arm, the lead cross arm, the low voltage line cross arm and the high voltage line cross arm are successively and fixedly connected between the two electric poles from bottom to top, the transformer is fixedly connected above the transformer and distribution box cross arm, the low voltage distribution box is fixedly connected below the transformer and distribution box cross arm, and the grounding down leads are arrangedon the side parts of the electric poles. The teaching work instrument is reasonable in structure and convenient to use, each component is reduced in equal proportion relative to actual court equipment, the teaching work instrument is made of engineering plastic materials, carrying and assembly are convenient, uniform standards of all construction units can be ensued by using the teaching work instrument, the efficiency of construction is improved, teaching and learning are convenient, at the same time, operation and maintenance personnel of distribution network equipment can visually judge thesituation of each equipment part on a site through the teaching work instrument, and the overall professional level of a distribution network can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of distribution network electric power construction, in particular to a teaching instrument for standardization of distribution network substations. Background technique [0002] During the erection of power distribution network construction, it is necessary to set up a distribution transformer station area that transforms high-voltage electricity into low-voltage electricity; pole-mounted transformer stations are called pole-mounted transformer stations that install transformers on poles with brackets. . It is used in places with small electric capacity and scattered loads. It is divided into single pole variable radio and double pole variable radio. [0003] The high-voltage side of the rack-type substation is led overhead, and the low-voltage side is led to the users with cables. Drop-out fuses and isolating switches are generally used on the high-voltage side, and lightning arresters should be install...

AI Technical Summary

Problems solved by technology

[0005] In the construction of existing distribution network projects, professional technicians or experienced construction personnel are usually required to guide the erection of substations on site. Due to the height of substations and the large number of equipment parts, it is not convenient to observe and judge the conditions of various equipment parts on site. , affect the construction efficiency of the substation area, and even cause problems such as installation errors
