Motor-operating mechanism is used for driving CM, CV type load ratio bridging switch, and without the excitation tap
Switch.The environment for use of motor drive mechanism must satisfy following condition:
1, sea level elevation is no more than 2000m, must specially indicate if surpass;
2, environment temperature be not higher than+55 ℃, be not less than-25 ℃;
3, the perpendicularity deviation with ground level is no more than 5%;
4, the installation site is without serious dust and other explosivities and corrosive gas.
Motor drive mechanism is by casing, mechanical rotating mechanism, position indicating device, appliance controling element
Form Deng part.
Shunting switch is important ingredient in the transformer, its complex structure, the characteristics such as volume is larger, and is not easy to assemble, all so that shunting switch teaching task difficulty strengthen.Traditional equipment in kind limits because of the place, and device-restrictive can't satisfy teaching purpose.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the invention provides three of a kind of 110kV combined type shunting switch
The dimension model system, the student can understand total and the characteristics of shunting switch on computers, and can carry out virtual assembling dismounting to shunting switch.Greatly improve the quality of teaching, also reduce the loss to equipment in kind simultaneously.
The present invention realizes with following technical scheme: a kind of 3D modelling system of 110kV combined type shunting switch, and this system has modeling engine, data engine, sound engine, script engine and logic engine, interrelated calling between each engine; With reference to drawing, and measure full size and outward appearance, then utilize modeling software, with 110kV combined type shunting switch from the inside to surface, all carry out three-dimensional modeling; Each independent part builds up the part body, and then the assembly relation interpolation geometrical constraint according to equipment assembles, and finally generates a cover 110kV combined type shunting switch three dimensional virtual models.
The invention has the beneficial effects as follows: native system is realized the digitizing of 110kV combined type shunting switch, and the student can understand total and the characteristics of shunting switch on computers, and can carry out virtual assembling dismounting to shunting switch.Greatly improve the quality of teaching, also reduce the loss to equipment in kind simultaneously.
