Description

A teaching mold for low-voltage distribution station area

technical field

The utility model relates to a mold equipment for electric power teaching, in particular to a teaching mold for a low-voltage distribution station area.

Background technique

The low-voltage distribution station is a relatively important power supply work area in the grass-roots power supply equipment. The principle of the grass-roots power supply is to use a transformer to convert high-voltage electricity into a low-voltage power output that can be used in production and life. At present, the low-voltage distribution station generally adopts high-voltage input The advantage of this type of installation is to save resources and reduce the input cost of the power department, but its disadvantages are also obvious. In daily maintenance, if a fault occurs in a low-voltage line, it needs to be repaired. In order to ensure a safe distance, it is often necessary to cut off the high-voltage transmission line to cause a large-scale power outage, which brings losses to people's production and life. In view of this situation, the inventor proposed the design of the teaching mold to improve the traditional low-voltage power distribution of existing electric workers. Knowledge of district design and installation and study of the design.

Utility model content

The technical task of the utility model is to provide a low-voltage power distribution station area teaching mold for the above-mentioned deficiencies in the prior art.

The technical scheme adopted by the utility model to solve its technical problems is: a teaching mold for low-voltage distribution station area, including base, fence, high-voltage pole, low-voltage pole, transformer, cross arm, lightning arrester, drop fuse, high-voltage line, High-voltage cables, branch cables, low-voltage lines, low-voltage cables and JP cabinets, wherein the JP cabinet is equipped with a switch, and the base is fixed with two high-voltage line poles and two low-voltage line poles, and the high-voltage line poles are respectively set In the middle of the base and the low-voltage line pole is set outside the high-voltage line pole, the lightning arrester, drop fuse, transformer and JP cabinet are fixed on the high-voltage line pole through cross-arms, wherein the input end of the transformer is connected to the high-voltage line pole by a high-voltage cable The high-voltage line erected on the top is connected, and the output end is connected to the switch in the JP cabinet through cables. The low-voltage line is erected on the top of the low-voltage line pole and connected to the switch in the JP cabinet set on the high-voltage line pole through a low-voltage cable.

Further, the low-voltage cables between the high-voltage line poles and the low-voltage line poles are buried in the ground, and the exposed parts on the ground are provided with cable protection sheaths.

Further, a wooden fence with a height of not less than 1.4-2m is arranged around the high-tension pole.

The beneficial effects of the utility model are as follows: 1. The design is reasonable, intuitive and easy to understand, and is convenient for electric power practitioners to grasp quickly. 2. The biggest advantage of this design is that when a local low-voltage line fails, you only need to disconnect the switch in the JP cabinet for safe inspection and maintenance, avoiding losses caused by large-scale power outages.
