When measuring the insulation resistance of a capacitor using an insulation resistance meter, first disconnect the power supply and load connected to the capacitor, and then discharge.
(1) Check that the voltage and measurement range of the insulation resistance meter meet the requirements of the capacitor and inspect the insulation resistance meter.
(2) When measuring electrolytic capacitors, pay attention to the positive and negative polarity of the insulation resistance meter. The positive pole is connected to the positive (L) terminal, and the negative terminal is connected to the negative (E) terminal. It cannot be reversed. Otherwise, the capacitor will be broken down.
When measuring a non-polar capacitor, the corresponding connection of positive and negative polarity can be ignored.
(3) When measuring the insulation between the capacitor lead and its outer casing, the "L" end of the insulation resistance meter shall be connected to the lead pin of the capacitor, and the "E" end shall be connected to the outer casing of the capacitor.
(4) Shake the insulation resistance meter. Do not flicker and slow. When the pointer is stable after shaking for about 1min at 120r/min, the data read is the correct value. After the measurement is over, the capacitor should be discharged.
A high-speed slip ring is an electromechanical device that allows electrical current to pass between a stationary and a rotating assembly. It is typically used in applications where the speed requirement exceeds that which is achievable with a standard slip ring. High-speed slip rings are available in a variety of sizes and configurations to meet the needs of most applications. They are commonly used in military, aerospace, and medical applications where speed and reliability are critical.
The speed is required to be at least tens of thousands of revolutions per minute, the structure of the Conductive Slip Ring directly determines the contact of high speed, as well as the size of impedance. High-speed slip ring materials have high wear resistance, high life characteristics, and multi-contact contact can ensure signal transmission and power reliability, with the development of science and technology, high-speed slip rings will be more and more widely used.
If you need to transfer large amounts of data or power between two stationary objects, a high-speed conductive slip ring is what you need. Traditional slip rings only offer a few thousand revolutions per minute (RPM), which is more than enough for most applications, but can be limiting in some circumstances. Some applications, like those found in the medical or military field, require speeds of tens of thousands of RPM in order to function properly. That's where our high-speed conductive slip ring comes in. With speeds up to a certain range, it can handle even the most demanding applications.
