Frequency conversion speed regulation control device for high altitude tourist car

Abstract

The invention relates to a frequency conversion speed regulation control device for a high altitude tourist car, which is formed by an air switch, electrothermal relays, motors, brakes and the like. The frequency conversion speed regulation control device is characterized in that: a frequency converter is arranged between the air switch and the motors as well as the brakes to control the revolving speed of the tourist car motor, wherein the connections between the air switch and the frequency converters, between the frequency converter and the electrothermal relays as well as the brakes, and between the electrothermal relays and the motors are all electric connections. The frequency conversion speed regulation device is added on the high altitude tourist car to solve the problem that great impact force at the time of starting and closing down and high running energy consumption exist in the traditional high altitude tourist car.

Description

Technical field:

[0001] The invention belongs to the technical field of electromechanical control. Background technique:

[0002] The power of the current high-altitude observation vehicle is provided by the motor, but its speed is not adjustable. Invention content:

[0003] The technical problem to be solved by the present invention is: the purpose of the present invention is to provide a high-altitude observation vehicle with a frequency conversion speed regulation control device. The traditional high-altitude observation vehicle is powered by a motor, but because it cannot adjust the speed, it has a large impact force and high energy consumption when starting and stopping, and consumes a lot of energy when there are few or no passengers.

[0004] The technical solution adopted by the present invention to solve the technical problem is as follows: a high-altitude observation vehicle frequency conversion speed regulation control device, which is composed of an air switch...

Examples

Embodiment

[0008] Example: as attached figure 1 As shown, the air switch 1 controls the on and off of the power supply. The frequency converter 2 is connected behind the air switch 1, and the power is sent to the motor 4 all the way after the frequency conversion by the frequency converter 2, and the speed control of the motor is carried out. In order to protect the motor, a thermal relay is connected in series between the frequency converter 2 and the motor 4 3; The other path is sent to the brake 5 for braking control of the motor 4.
