Intelligent simulation distribution box

Abstract

The invention discloses an intelligent simulation distribution box. According to the intelligent simulation distribution box, a vertical fixed plate is arranged inside a box body, an intelligent distribution transform terminal unit and a capacitor unit are arranged on the upper row of the front side of the fixed plate side by side, a wire inlet / outlet unit is arranged on the lower low of the front side of the fixed plate, a metering and measuring unit is arranged on the back side of the fixed plate, a wire inlet is formed in the side wall of the box body, the wire inlet / outlet unit comprises a molded case circuit breaker, a junction box, a voltage terminal, a current terminal, a wiring terminal, a miniature circuit breaker, a temperature relay and a hurl-slices switch, the metering and measuring unit comprises an intelligent ammeter, a metering current transformer, a monitoring current transformer, a first capacitor current transformer, a second capacitor current transformer and a residual current action protector, the intelligent distribution transform terminal unit comprises an intelligent distribution transform terminal, a power indicator light and a cooling fan, and the capacitor unit comprises a self-healing power capacitor and a capacitor indicator light. The intelligent simulation distribution box has the advantages that the outage frequency is low, and power supply continuity is high.

Description

technical field [0001] The invention belongs to the technical field of rural power grids, in particular to an intelligent analog distribution box. Background technique [0002] China's rural power grid has already established a certain foundation after large-scale rural power grid transformation, but there are still generally insufficient infrastructure investment, unreasonable grid structure, and relatively backward technological means. It is economical, practical and effective, and will be constructed in stages. [0003] At present, the teaching and training of the rural grid intelligent power distribution system based on the intelligent low-voltage distribution box of the rural grid and the relevant skills of user load and measurement at home and abroad are only on-site education and operation demonstration in the way of masters and apprentices. Due to the singleness of the on-site situation, the master cannot demonstrate the failure of the intelligent low-voltage distri...

[0002] China's rural power grid has already established a certain foundation after large-scale rural power grid transformation, but there are still generally insufficient infrastructure investment, unreasonable grid structure, and relatively backward technological means. The characteristics of economic benefits, practical results, construction in stages

[0003] At present, the teaching and training of the rural grid intelligent power distribution system based on the intelligent low-voltage distribution box of the rural grid and the relevant skills of user load and measurement at home and abroad are only on-site education and operation demonstration in the way of masters and apprentices. Due to the singleness of the on-site situation, the master cannot demonstrate the failure of the intelligent low-voltage distribution box of the rural power grid, the problems and solutions of the single-phase and three-phase metering users and the main station software system, and can only adopt the teaching method of solving problems when they arise, so that there are It is impossible to reproduce the possible fault phenomena that may occur in the operation of the intelligent low-voltage distribution box of the rural power grid. At the same time, the test operation data of the intelligent distribution transformer terminal software of the rural power grid is single, and it is impossible to carry out personalized assessments for multiple students. This kind of teaching The method is not conducive to students' understanding and learning, and has been criticized a lot in teaching practice

With the development of smart grid, especially after the large-scale promotion of intelligent upgrading and transformation of rural power grid, there are people who are not familiar with new equipment and new products. problem

The expansion of the traditional power distribution box takes a long time, requires many procedures, debugging is difficult, and the quality is difficult to guarantee. The power distribution part and the reactive power compensation part are mixed together, making maintenance inconvenient
