Causes of common oil leakage in high and low voltage distribution cabinets

  Common faults of high and low voltage distribution cabinets include air in and out and oil leakage
Oil leakage of high and low voltage distribution cabinets can be divided into internal leakage and external leakage, and external leakage can be divided into weld leakage and sealing surface leakage 1
there is oil leakage at the welding position, mainly due to poor welding quality
If leakage has occurred, find out the leakage point first and do not omit it
For the parts with serious leakage, metal tools such as flat shovel or sharp punch can be used to rivet the leakage point
After controlling the amount of leakage, the treatment surface will be cleaned
At present, polymer composite materials are mostly used for curing
After curing, the purpose of long-term treatment of leakage can be achieved 2
causes of oil leakage and poor sealing of seals
Fushi blue material can be used for bonding to form a whole joint and greatly control oil leakage; If the operation is convenient, the metal shell can also be bonded at the same time to achieve the purpose of leakage control In daily life, we can't wait for the distribution cabinet to be repaired when there is a problem
In the process of daily use, there are still many places that need to be maintained
Now Henan Boyuan Complete Electrical Co
, Ltd
will share with you the aspects that need to be maintained:   1
After the vacuum circuit breaker trolley in the high and low voltage distribution cabinet is closed in the test position, the trolley circuit breaker cannot enter the working position
(prevent on load closing)   2
When the grounding knife in the high and low voltage distribution cabinet is closed, the trolley circuit breaker cannot be closed
(prevent closing with grounding wire)   3
When the vacuum circuit breaker in the high-voltage and low-voltage distribution cabinet is closed, the machinery on the grounding knife at the rear door of the panel and cabinet is locked with the cabinet door
(prevent entering the live Bay by mistake) 4
The vacuum circuit breaker in the high and low voltage distribution cabinet is closed during operation, and the grounding knife cannot be put into operation
(prevent live hanging of grounding wire)   5
When the vacuum circuit breaker in the high and low voltage distribution cabinet is switched on, it cannot exit the working position of the trolley circuit breaker
(prevent loaded broach switch         distribution cabinet manufacturer: http://www
