Liner arrangement and a circuit breaker with a liner arrangement and method for protecting an insulator body

It is proposed a liner arrangement (100) for fitting a tubular insulator body (201) in a circuit breaker (300). The liner arrangement includes a planar, electric-arc resistant and heat resistant liner layer (105) comprising a first edge portion (101) and a second edge portion (102) that is located o...

Summary:It is proposed a liner arrangement (100) for fitting a tubular insulator body (201) in a circuit breaker (300). The liner arrangement includes a planar, electric-arc resistant and heat resistant liner layer (105) comprising a first edge portion (101) and a second edge portion (102) that is located opposite the first edge portion, wherein the first edge portion (101) has a first contour (103) extending in a direction transversally to a plane defined by the planar liner layer (105). The second edge portion has a second contour (104) having a geometry that is complementary to the first contour (103) 10 such that the first edge portion (101) can be attached by way of a form fit to the second edge portion (102) once the planar liner layer (105) is bent to a tubular shape. Further, a circuit breaker including a liner arrangement and an insulator is described. A method for protecting an insulator body (201) of a heat chamber insulator (200) for a circuit breaker is also described. Figure 1 93282
