, Description:
TECHNICAL FIELD
[0001] The present invention relates to protection enclosures and, more particularly, relates to a safety apparatus for enclosing terminals of high voltage electrical handling devices, such as transformers, generators, alternators, and the like, and still providing safe access to the terminals during maintainace.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] In electric utility networks, electrical power switchyards or utility stations and substations are commonplace to house and isolate high voltage electrical handling devices (also interchangeably referred to as power source applications, high power electrical handling devices and high power devices) such as power transformers, generators, and alternators which are essential for the transmission and distribution of electricity. In design, the transformers are conventionally connected to electrical devices or switching networks containing circuit breakers and switchgears to which the power lines are connected.
[0004] Taking case of transformer application, while the transmission and distribution of electricity, in operation, output of transformer bushings (typically used for allowing an electrical conductor to pass safely through the transformers) is connected to incoming side of an electrical device enclosure as an input and the outgoing side of the electrical device i.e., an output is used for a load. However, at times user bypasses the electrical device to fulfill additional load requirements and take the output from the incoming side of the electrical device due to which transformer gets overloaded that causes overheating which can deteriorate its life.
[0005] To overcome the overheating and deterioration problems of transformers, prior-art utilizes metal conduit wires at the incoming side. However, a technical problem of utilizing the metal conduit wires at incoming side is that individual phase wires of the transformer and/or the electrical device are still accessible to the user from line terminal of the electrical device. Thus, to safeguard against the danger associated with prominently exposed energized component inherent with the live-front design of high voltage electrical handling device, the positioning of high voltage electrical handling device therefore requires pole mounting and/or isolation within large secured switch yard or substations or the high voltage electrical handling device to be enclosed in enclosure (or protection devices) or the electrical devices needs to be enclosed in enclosure (or protection devices) or at least the individual phase wires needs to be enclosed in the enclosure (or protection devices). The currently available enclosures (or protection devices) separately encloses outgoing terminal of high voltage electrical handling device and incoming terminal of the electrical device, still allowing access to the outgoing terminal and the incoming terminal.
[0006] Also, during maintenance, the electrical device should be in OFF condition to safeguard against the danger associated with prominently exposed energized component inherent with the live-front design of the electrical device. However, electrical device state can be changed during maintenance in case the electrical device is not used with any external accessories where protection for locking electrical state is provided. To achieve this, the electrical device needs to be provided with external accessories by means of which the lock condition is ensured. In the existing technology there is safety risk as no such provision is provided for maintaining the OFF state.
[0007] Therefore there is a dire need to solve the above technical problems by providing a new, technically advanced, safe and protecting enclosure apparatus which encloses the outgoing terminal of the high voltage electrical handling device and the incoming terminal of the electrical device to prohibit access of line terminals to the user. Further, there is also a need to solve the above technical problems by providing an enclosure apparatus with an accessible mechanism to allow easy access to the line terminals during maintainace with an aided OFF state locking mechanism of electrical device.
[0008] As used in the description herein and throughout the claims that follow, the meaning of “a,” “an,” and “the” includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise.
[0009] In some embodiments, the numerical parameters set forth in the written description and attached claims are approximations that can vary depending upon the desired properties sought to be obtained by a particular embodiment. In some embodiments, the numerical parameters should be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. Notwithstanding that the numerical ranges and parameters setting forth the broad scope of some embodiments of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as practicable. The numerical values presented in some embodiments of the invention may contain certain errors necessarily resulting from the standard deviation found in their respective testing measurements.
[0010] The recitation of ranges of values herein is merely intended to serve as a shorthand method of referring individually to each separate value falling within the range. Unless otherwise indicated herein, each individual value is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g. “such as”) provided with respect to certain embodiments herein is intended merely to better illuminate the invention and does not pose a limitation on the scope of the invention otherwise claimed. No language in the specification should be construed as indicating any non-claimed element essential to the practice of the invention.
[0011] Groupings of alternative elements or embodiments of the invention disclosed herein are not to be construed as limitations. Each group member can be referred to and claimed individually or in any combination with other members of the group or other elements found herein. One or more members of a group can be included in, or deleted from, a group for reasons of convenience and/or patentability. When any such inclusion or deletion occurs, the specification is herein deemed to contain the group as modified thus fulfilling the written description of all groups used in the appended claims.

Numerous modifications, changes, variations, substitutions, and equivalents will be apparent to those skilled in the art, without departing from the spirit and scope of the disclosure, as described in the claims.

ADVANTAGES OF THE INVENTION
[0084] The present disclosure provides an integrated enclosure protecting an outgoing terminal of high voltage electrical handling devices and associated electrical device terminals.
[0085] The present disclosure provides an integrated enclosure with aided OFF state locking mechanism of electrical device.
[0086] The present disclosure provides an integrated enclosure for isolating an outgoing terminal of a source (application like transformer, DG or alternator etc.) and incoming terminals of electrical device from the user, exposing only outgoing terminals of electrical device.
[0087] The present disclosure provides an integrated enclosure which enables access only to outgoing terminals of electrical device to the user, and prohibits access to incoming terminal of electrical device to the user, during maintenance of electrical device.
[0088] The present disclosure provides an integrated enclosure which ensures OFF condition of the electrical device during maintenance.
[0089] The present disclosure provides an integrated enclosure that isolates source outgoing and electrical device incoming terminal through integrated enclosure during running and maintenance condition of device, and ensures the OFF state of the electrical device in case of maintenance without the aid of any external accessories. Thus, the integrated enclosure prevents the problems of overheating and life deterioration of applications/products like transformer, DG or alternator etc. where the user at times bypass the protection device and takes output directly from its incoming side.
