VS1 Vacuum Termer Touch Arm Maintenance and Replacement
2023-08-01
VS1 vacuum circuit breaker can only have a hand cart. Touch arms are most easily overlooked when we maintain or repair. Why is it easy to be ignored in our maintenance. It is because the tactile arm is not easy to damage, and it can generally be discovered when it is overheated or burned. At this time, it was found that the correct tentacle was unavailable. Therefore, the touch arm of the VS1 vacuum circuit breaker also needs maintenance and replacement. I hope this article can attract electricians who use vacuum circuit breakers.
For better maintenance and replacement of the touches of the vacuum circuit breaker, let's first understand the functions and functions of the touch of the arm. The function of touching the arm is responsible for connecting the vacuum arc destroyer and plum blossoms. Another role is to participate in the depth of the cabinet in the adjustment. For example, the depth of the medium cabinet needs to be deepened, so the tactile arm is extended proportionally. If the depth of the middle cabinet does not need to be so deep, then reduce the arm size by proportion. And each region is a bit different in the depth of the mid -to -center cabinet, so you need to adjust it by touching the arm.
The material of the tactile arm has a very impact on the current. The tactile material is generally copper or aluminum. Generally, below 1600A is the aluminum tossing arm. Unless there are special requirements, you must use copper to touch the arm, or the general important position is used to use the copper tactile arm. And more than 1600A uses copper -tossing arm, and there are certain requirements for the silver -plated layer. It is difficult to achieve this current for large current aluminum.
After understanding these, we have a certain understanding of the maintenance and replacement of tentacles. If we reach the maintenance time, we must clean up the arm in time and observe whether the installation screw is loose. If you find that there are loosening, you must tighten. Otherwise, it will cause virtual connection, leading to the burning of the arm, and seriously may cause the real vacuum circuit breaker to burn. If possible, you can install the temperature measurement sensor on the touches, and always measure the temperature of the vacuum circuit breaker to better protect the circuit breaker. Especially large current vacuum circuit breakers.
If you change your arms, you must change the time limit when the arm is touched, or there is hot hair. Please replace it in time in time. Replacement can be replaced according to the original size. It should be noted that you need to be plated on the surface of the tactical arm.

The above is the full excess of maintenance of tentacles and replacement.
