The function of insulation cover: An insulation cover is a protective cover used to shield live or non live conductors. When the safety distance between workers and live parts cannot meet the requirements、 in order to prevent workers from getting electric shock、 insulation covers can be placed on the live parts. The insulation cover can be used as insulation protection for power equipment such as distribution transformers、 pole mounted circuit breakers、 vacuum circuit breakers、 SF、 circuit breakers、 and various types of wall bushings、 busbars、 outdoor busbar bridges、 indoor busbar bridges、 and various post insulators
Test method: For masks with different functional types.
. Different types of electrodes should be used. The electrode inside the shielding cover is usually a metal core rod and placed in the center of the cover. The outer electrode of the shielding cover is a grounding electrode made of conductive materials such as metal foil or conductive paint. Apply a power frequency voltage between the test electrodes as specified in the table for a duration of 5 minutes. During the test、 there should be no flashover or breakdown of the test object. After the test、 all parts of the sample should have no signs of burning or heating. Precautions for use and storage of insulation cover: (1) Before using the insulation cover、 it should be checked whether the insulation cover is intact and whether it has exceeded the validity test period. (2) Check whether the insulation cover is clean inside and outside、 and there should be no cracks or damage. And the surface of the insulation cover should be wiped clean. (3) When placing insulation covers on site、 insulated rods should be used and insulated gloves should be worn. (4) The placement should be secure. Insulating covers should be installed on the outgoing side isolation switches that may have the possibility of reverse power transmission. (5) The insulation cover should be uniformly numbered and stored indoors on a dry tool rack or cabinet
