Embodiment Construction

[0072] refer to figure 1 , shows an inductive device 10 such as a transformer rated at 60 MVA or higher. It should be understood that the inductive device 10 may be implemented as a power transformer, a distribution transformer or a shunt reactor, and depending on the application, be single-phase or multi-phase, eg three-phase. The induction device 10 has the ruggedization features described herein applicable to newly manufactured transformers, and these ruggedized features may be retrofit to existing transformers in service and in service.

[0073] The sensing device 10 is designed to address areas prone to failure due to ballistic projectiles and other intrusions. Certain areas of the sensing device 10 are provided with protective material to deflect direct impacts, eg by projectiles, while other areas utilize sensors to detect damage and switch to a backup system to protect the core and coil windings. Core and coil windings (also known as the active part of the transforme...

Abstract

A hardened inductive device and systems and methods for protecting the inductive device from impact is provided. The inductive device is hardened with protective coating and / or an armor steel housing. The hardened inductive device is protected from impact by an object such as a bullet and leakage of dielectric fluid is prevented. Acoustic and vibration sensors are provided to detect the presence and impact, respectively, of an object in relation to the inductive device housing. The measurements of the acoustic and vibration sensors are compared to thresholds for sending alarms to the network control center and initiating shut-down and other sequences to protect the active part. The acoustic sensor results are utilized to determine the location of origin of the projectile.

Description

technical field [0001] The present invention relates to sensing devices that are resistant to catastrophic events. Background technique [0002] Inductive devices such as power transformers and other electrical equipment are often located outdoors and are subject to environmental, animal and human factors. In particular, harsh human behavior and extreme weather can cause damage to electrical equipment outside (rather than inside buildings). Even seismic events can cause damage to transformers. It may take a considerable amount of time to remedy the damage and bring the electrical equipment back into operation, which may result in a power outage. Contents of the invention [0003] An induction device having a tank having a top wall, a bottom wall and side walls, and each of the top wall and the side walls has an outer substrate surface. A core is disposed within the interior volume of the tank, the core having at least one core arm extending between a pair of yokes, at l...
