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.

[0004] There is, therefore, a need of a protection device for the
switchgears, which is capable of protecting the switchgear in case of flood.

[0023] In the following description, numerous specific details are set forth
in order to provide a thorough understanding of embodiments of the present
invention. It will be apparent to one skilled in the art that embodiments of the
present invention may be practiced without some of these specific details.
[0024] The present disclosure relates to the field of a switchgear and more
particularly the present disclosure relates to a flood protection device for the
switchgear.
[0025] The present disclosure elaborates upon a flood protection device
for a switchgear. The protection device includes a housing, having an electrical
circuit, with plurality of holes at base of the housing for entry of the flood water.
The electrical circuit is electrically open until the flood water enters the housing.
An actuating device operatively configured with a circuit breaker of the
switchgear, and configured to trip the switchgear; and a control circuitry
operatively configured with the electrical circuit and the actuating device, the
control circuit is configured to detect electrical close of the electrical circuit and
correspondingly send a first set of signals to the actuating device. The first set of
signals facilitates tripping of the switchgear through the circuit breaker.
[0026] In an embodiment, the control circuit can comprise any or
combination of a transmitter, receiver, and a processor.
[0027] In an embodiment, the flood protection device can be installed at a
bottom of the switchgear. Position and height of installing the flood protection
device can be varied based on requirement.
[0028] In an embodiment, the actuation device can comprise a relay.
[0029] In an embodiment, the housing can comprise an electrically open
circuit which is electrically closed by flood water entering the housing through
plurality of holes.
[0030] FIG. 1A-B illustrates exemplary representation of a flood
protection device configured with a switchgear, in accordance with an
embodiment of the present disclosure.
[0031] As illustrated, a flood protection device for a switchgear 200 can
includes a housing 102. The housing 102 can be made of material such as but not

limited to metal, fibre, and plastic. The housing 102 can be provided with plurality of holes 104 at base of the housing for allowing entering of the flood water inside the housing 102. The plurality of holes is covered with cloth like material from inside (which allow the flow of flood water from outside to inside). This arrangement can prevent the entry of insects, vermin's and dust which may harm the set up. The housing 102 can include an electrical circuit which is normally open and is configured to be electrically closed by flood water entering the housing.
[0032] In an embodiment, the electrical circuit is electrically open until
the flood water enters the housing 102. The flood protection device can include an
actuating device 106 than can be operatively configured with a circuit breaker (not
shown) of the switchgear 200. The actuating device 106 can be configured to trip
the switchgear 200 by tripping the circuit breaker. A control circuitry can be
operatively configured with the electrical circuit inside the housing 102 and the
actuating device 106. The control circuit can include but not limited to a
transmitter 108-1, a receiver 108-2, and a processor. The transmitter can be
electrically configured with the electrical circuit inside the housing 102 and the
receiver can be electrically configured with the actuating device 106.
[0033] In an embodiment, the transmitter of the control circuit
(transmitter) can be configured to detect electrical close of the electrical circuit inside the housing 102 and correspondingly send a first set of signals to the, through the receiver, actuating device. The first set of signals can facilitate tripping of the switchgear through the circuit breaker and also the tripping of a main breaker present in an upstream of the power grid to avoid any damage by flood. The first set of signals can be used also to alert an upstream supply of the flood situation in downstream. The first set of signals can also be used to initiating an alarm etc. The flood protection device 100 can be installed at a bottom (or at desired level) of the switchgear 200. In an embodiment, the actuation device can comprise but not limited to a relay.
[0034] Moreover, in interpreting the specification, all terms should be
