High-voltage safety locks of the personal computer

For protection of measuring transformers of tension release safety locks like PKN (the former name PKT). Unlike the considered PKT safety locks they have the konstantanovy fusible insert which is reeled up on the ceramic core. Such insert has higher specific resistance. Thanks to this and small section of an insert the current-limiting effect is provided. Identification number of high-voltage safety locks of PKT: PKT 102-10-50-12,5 U3 P - a safety lock To - with a quartz filler of T - for protection of power transformers, air and cable lines, condensers, electric motors; 102-three-digit number, design designation: 101; 102; 103; 104; 10-rated voltage, kV: 3; 6; 10; 35; 50 - rated current, And: 2; 3,2; 5; 8; 10; 16; 20; 25; 31,5; 40; 50; 80; 100; 160; 200; 315; 12,5 - rated current of shutdown, kA: 8; 12,5; 20; 31,5; 40; 50; U3 - climatic modification and category of placement in accordance with GOST 15150-69: U1, UZ V existence is available the personal computer 6-10,20,30,40,50,60,80,100A PKTN 6-10 personal computer 10-10,20,30,40,50,60,80,100A
