Abstract
Provided is a silicon controlled rectifier demonstration teaching tool which comprises a demonstrating board with a rectangular structure and a running water lamp string. A silicon controlled rectifier trigger control circuit is placed on a surface of the demonstrating board. The running water lamp string is laid along the main circuit of the silicon controlled rectifier and at the outer side of the silicon controlled rectifier trigger control circuit. The two ends of the running water lamp string are arranged at the two ends of the battery of the silicon controlled rectifier trigger control circuit. One end of the running water lamp string is connected with one end of a power plug, while the other end of the running water lamp string is connected with the other end of the power plug. Compared with a product in the prior art, the silicon controlled rectifier demonstration teaching tool has advantages of a simple structure, easy use, low cost, and capability of visually demonstrating the conducting process of the silicon controlled rectifier.
Description
Technical field
The utility model relates to a kind of teaching aid, is specifically related to a kind of controllable silicon demonstration teaching aid.
Background technology
Controllable silicon is the important content of electric information electrical category professional teaching, and because the silicon controlled conducting process is abstract, the silicon controlled conduction property is the difficult point of Students ' Learning.
The utility model content
The purpose of this utility model is exactly the defective that exists for prior art, and a kind of controllable silicon demonstration teaching aid is provided.
Its technical scheme is: the demonstration board and the running lamp string that comprise rectangular configuration.Described demonstration board is decorated with the thyristor trigger circuit on one plane, in the thyristor trigger circuit outside, lay a running lamp string along the controllable silicon major loop, the two ends of running lamp string are arranged on the battery two ends of thyristor trigger circuit, one end of running lamp string is connected with an end of attaching plug, and the other end is connected with the other end of attaching plug by switch.
The utility model has advantages of simple in structure, easy to use, with low cost and energy ocular demonstration controlled silicon conducting process compared with prior art.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
With reference to Fig. 1, a kind of controllable silicon demonstration teaching aid comprises demonstration board 1 and the running lamp string 3 of rectangular configuration.Described demonstration board is decorated with thyristor trigger circuit 2 on 1 one planes, in thyristor trigger circuit 2 outsides, lay a running lamp string 3 along the controllable silicon major loop, the two ends of running lamp string 3 are arranged on the battery two ends of thyristor trigger circuit 2, one end of running lamp string 3 is connected with an end of attaching plug 5, and the other end is connected by the other end of switch 4 with attaching plug 5.
During use, attaching plug 5 is inserted power supply, when serving as a teacher explanation to controlled silicon conducting, open switch 4 and get final product.At this moment, running lamp string 3 namely can produce the flash of light of flowing water shape, the flow direction of demonstrating current.
