Abstract

PURPOSE: To improve the durability and reliability of a transformer protective device, by mounting a plurality of physical quantity detecting elements to a transformer, and by collecting the display of the quantity of electricity from each detecting element to a protective instrument board installed near the transformer.
CONSTITUTION: A temperature detecting element 6, an oil surface level detecting element 7, an oil flow rate detecting element 8 and an impact pressure detecting element 9 are installed to the different points of a transformer body 1, and detecting value converted into each quantity of electricity is fed to a protective instrument board 10, which is mounted near the transformer body 1 and to which inside an indication meter and a relay operated by the quantity of the indication are installed. Thus, such constitution can improve the durability and reliability of this protective device because maintenance and inspection can simply be performed while the detecting elements can be produced in stronger structure than meters.
