Theory of Ultra-Low Frequency Dielectric Strength Test

Ultra-low frequency dielectric strength test is an alternative method of power frequency withstand voltage test.As we know, due to the large capacitance of the insulating layer, a large-capacity test transformer or resonant transformer is required to perform power frequency withstand voltage tests on large generators and cables. Huge equipment is not only cumbersome, but also expensive and unsuitable for use.

AMR robots have been one of the most discussed forms of automation technology in manufacturing and distribution centers. The potential to have automated transportation is a huge benefit to save on costs but also to fight off labor shortages. In this post, we will go through the very basics of this type of technology and help you understand what makes an AMR robot such a polarising piece of technology.

The AMRs require incredibly sophisticated sensors to be fitted in their unit in order for them to navigate so well. Although several environmental sensors can be used, laser scanners and LiDAR sensors are most frequently employed. LiDAR scanners operate by sending out light pulses that strike various surfaces and bounce the light back to the sensor, where it is once more detected. The length of time it took for the light to be sent back to the sensor will then be determined by the AMR's processing system. This enables the LiDAR sensors to map the separation between certain objects and gives the AMR robot information about the areas it can and cannot travel in.

1. the road surface shall be flat and clean without obvious fluctuation. The inclination is not higher than 5%, the robot
can not stop or turn at the ramp, step and gap, but can only pass quickly perpendicular to the ramp, step and gap.

2. positioning accuracy usually refers to the repetition accuracy of the robot navigating to the target site. When the
environment scanned by the robot's lidar is relatively stable, the repetition accuracy of the robot navigating from a fixed
direction to the target site can reach the expected value. When the robot marsh virtual path is running, it will try to fit the path, but the repeatability is not guaranteed. That is to say, the robot can ensure the accuracy of the arrival point, but not the path fitting accuracy. The minimum station
spacing supported 1CM, Therefore, the robot cannot be used as a linear guide rail.

3. basic functions include map editing, model editing, positioning module, navigation module, basic motion model
(differential), API interface, etc.

4. it shall be used with the qualified automatic charging pile

5. AMR is only designed for indoor transportation and is not recommended for outdoor environment.
