Technologies for preventing the explosion of electrical transformers

Abstract

An adaptor (11) for an electrical transformer explosion prevention device comprising: a first drilled interface (111) in a first region of a lower wall; a second drilled interface (112) in a first region of an upper wall, the first drilled interface and the second drilled interface being concentric with a first axis; a first set of bolt holes positioned about the first drilled interface such that the adaptor can be secured to a transformer tank outlet (2c); and an adaptor outlet (113a) with an adaptor outlet flange (113) secured to a second region of the upper wall and concentric with a second axis, for attaching a static spring pressure relief valve (22) to the adaptor outlet flange member. Devices and transformers comprising the adaptor, and control arrangements for controlling such devices and transformers, are also disclosed.
