Low-voltage transformer area simulation practical training device for rural network low-voltage distribution box

Abstract

The invention discloses a low-voltage transformer area simulation practical training device for a rural network low-voltage distribution box. The simulation practical training device comprises a simulation high-voltage inlet wire, a simulation transformer, a simulation low-voltage power source inlet wire, the rural network intelligent distribution box, a simulation low-voltage outlet wire, a low-voltage simulation user, a simulation loading power source, a fault simulator, a master station communication server and a master station system. The simulation practical training device is divided into two parts for simulating an indoor master station system part, a simulation loading system part and a transformer area and the low-voltage user on a pole, a simulation outdoor part simulates a 10kV high-voltage inlet wire in the mode that the wire enters above the pole, the high-voltage inlet wire simulates high-voltage inlet wire control through a falling type fuse protector, a real high-voltage wire and a real falling type fuse protector are adopted for the inlet wire, two simulation poles are arranged between two pieces of H-shaped steel, the simulation transformer is installed on the upper layer, the rural network intelligent distribution box is installed on the lower layer, and the simulation loading power source is placed in a room, and connected into the indoor rural network intelligent distribution box and a load of a low-voltage simulation user meter through cables. The simulation practical training device has the advantages of being high in reliability and stability.

Description

technical field [0001] The invention belongs to the technical field of rural power grids, in particular to a low-voltage station simulation training device for a low-voltage power distribution box in a rural power grid. 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 ma...

[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
