Description

Technical Field

[0001] This disclosure generally relates to a power system. More specifically, this disclosure relates to an electrical switchgear for the power system. Further embodiments of this disclosure relate to the vent compartment of the electrical switchgear. Background Technology

[0002] Electrical switchgear is used in power distribution systems to distribute power and selectively isolate electrical loads. Switchgear is manufactured in various forms. Typically, switchgear comprises a combination of electrical components such as disconnecting switches, fuses, circuit breakers, and main distribution busbars or busbars. Switchgear is installed in appropriate locations within the power system to connect and disconnect power under normal operating conditions or abnormal operating conditions, such as overloads and short circuits caused by internal or external factors. Circuit breakers protect the power system from damage caused by excessive current flow due to overloads or short circuits. Circuit breakers interrupt current paths by disconnecting contacts and interrupt current flow when a fault is detected. The switchgear is located where power distribution, isolation, and / or protection are required. These switchgear installations are typically located in power generation, transmission, and distribution substations. In addition to residential or commercial applications, switchgear is also used in harsh environments with dust, chemical fumes, etc. Such foreign particles can enter the switchgear and may cause premature failure.

Furthermore, the air duct compartment 1004 is adapted to receive cooling air from the atmosphere and circulate the cooling air to the respective compartments through ventilation paths / channels.

[0035] Now combine Figure 1 refer to Figures 3 to 6 As described above, the air duct compartment 1004 of the switchgear 1000 is configured to be fixed to the top plate 10001 of the switchgear 1000. The air duct compartment 1004 of this disclosure includes a housing 10041. The housing 10041 includes a sidewall structure 10042. The sidewall structure 10042 may have a length L (refer to...). Figure 1The length can extend along the vertical axis V-V' of the switch cabinet 1000. The sidewall structure 10042 of this disclosure includes a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall. Each of the first, second, third, and fourth sidewalls of the sidewall structure 10042 extends by a length L in the vertical direction along the vertical axis V-V'. The sidewall structure 10042 can be defined as a cubic structure having a first end FE and an open second end SE. The open second end SE can be arranged on and fixed to the top plate 10001. The open second end SE is configured to surround a plurality of louvers defined on the top plate 10001 and is configured such that gas or cooling air can be exchanged between the housing 10041 of the air duct compartment 1004 and each respective compartment through the plurality of louvers. In addition, the housing 10041 can be covered by a top panel 10043 at the first end FE. The air duct compartment 1004 may also include one or more vents 10044. One or more vents in the airway compartment 1004 may be provided in the top panel 10043 (e.g. Figures 3 to 6 (as shown) and in the sidewall structure 10042 (such as Figure 2 (As shown). One or more vents defined in the top panel 10043 are indicated by reference numeral 10144, and one or more vents in the sidewall structure 10042 are indicated by reference numeral 10244. Each configuration shown in the above figures will be explained in detail below.

[0036] Now for reference Figures 3 to 6 The illustration shows an airway compartment 1004. In one embodiment, a top panel 10043 may include a first portion 10143 and a second portion 10243. The first portion 10143 of the top panel 10043 may be configured to abut against and be secured to a peripheral portion of a first end FE. The second portion 10243 of the top panel 10043 may rise from the first portion 10143 in a vertical direction along a vertical axis V-V', thereby defining one or more vents 10144 between the first portion 10143 and the second portion 10243. The airway compartment 1004 includes at least one baffle 10045. The at least one baffle 10045 is configured to selectively cover and expose the one or more vents 10144 defined between the first portion 10143 and the second portion 10243. Each of the at least one baffle 10045 may be disposed near each of the one or more vents 10044. One end of each of the at least one baffle 10045 is pivotally connected to a first portion 10143 of the top panel 10043. Each of the at least one baffle 10045 can be configured as follows: Figure 3 The first position A shown and as... Figure 4 The second position B shown is pivoted to selectively cover and expose the one or more vents 10044.

[0037] A first position A of each of the at least one baffle 10045 is configured to cover the one or more vents 10044. In a second position B, each of the at least one baffle 10045 is displaced away from the one or more vents 10044 to expose the one or more vents 10044. In one embodiment, each of the at least one baffle 10045 may pivot away from the one or more vents 10044 to a desired extent. A restraint RM may be disposed on the first portion 10143 and may be attached to each of the at least one baffle 10045. The restraint RM may be adapted to limit the displacement of each of the at least one baffle 10045 beyond the second position B. Furthermore, one of the at least one baffle 10045 may define a plurality of slits 10048 (see reference). Figure 5 The plurality of slits 10048 may be adapted to exchange gas or cooling air between the switch cabinet 1000 and the atmosphere when the at least one baffle 10045 is in the first position A.

[0038] like Figure 5As shown, at least one baffle 10045 defines a receiving pouch 10047. The receiving pouch 10047 is defined on the main surface of the at least one baffle 10045 facing the interior portion of the housing 10041. The receiving pouch 10047 may be defined by a pair of arms 10147 and a restraint 10247. In one embodiment, the pair of arms 10147 may be configured to project vertically from the main surface of the at least one baffle 10045. The pair of arms 10147 may be spaced apart by a distance X (i.e., each arm of the pair of arms 10147 may be defined along a side end of the at least one baffle 10045). Although the pair of arms 10147 are illustrated to project vertically, it is also contemplated that the pair of arms 10147 project at other predetermined angles relative to the at least one baffle 10045 without departing from the scope of this disclosure. Furthermore, the restraint 10247 may be connected and extend between the pair of arms 10147. The configuration of the pair of arms 10147 and the constraint 10247 relative to the at least one baffle 10045 defines a gap G. The gap G is configured to accommodate a filter element 10046. The filter element 10046 may be, but is not limited to, at least one of a high-efficiency particulate (HEPA) filter, an ultra-low particulate (ULPA) filter, an electrostatic filter, a media filter, a glass wool filter, a pleated filter, etc. Other feasible filters are also contemplated without departing from the scope of this disclosure. The filter element 10046 is displaceable relative to the at least one baffle 10045 between a first position A and a second position B. When the at least one baffle 10045 is in the first position A, the filter element 10046 is housed within the housing 10041; when the at least one baffle 10045 is in the second position B, the filter element 10046 is accessible to an authorized operator of the switch cabinet 1000.

[0039] Now for reference Figure 6 and combined Figure 1 , 3 Figures up to 5 illustrate a locking unit 10050 associated with each of the at least one baffle 10045. The locking unit 10050 is configured to lock the at least one baffle 10045 in a first position A and is operable to unlock the at least one baffle 10045, causing the at least one baffle 10045 to shift to a second position B. One embodiment of the locking unit 10050 is described below, but this should not be construed as limiting the scope of this disclosure. Figure 6As shown, the locking unit 10050 includes a lug T projecting from a side end of the at least one baffle 10045. The lug T projects substantially perpendicularly from another main surface of the at least one baffle 10045 facing the atmosphere. The lug T defines a hole configured to receive a locking bolt LB. The locking bolt LB can engage with an adjacent baffle of the at least one baffle 10045 to lock each of the at least one baffle 10045 relative to each other in a first position A. The locking bolt LB is operable to disengage from the adjacent baffle of the at least one baffle 10045, thereby displacing each of the at least one baffle 10045 to a second position B.

[0040] Now for reference Figure 2 The illustration shows another configuration of the airway compartment 1004. As described above, the sidewall structure 10042 can be defined as a cubic structure having a first end FE and an open second end SE. The open second end SE can be arranged on and fixed to the top plate 10001. The open second end SE can be configured to surround a plurality of louvers defined on the top plate 10001 and configured such that gas or cooling air can be exchanged between the outer shell 10041 of the airway compartment 1004 and each respective compartment through the plurality of louvers. Furthermore, the outer shell 10041 can be completely covered at the first end FE by the top panel 10043. The top panel 10043 can be configured to completely seal the first end FE. The airway compartment 1004 may also include one or more vents 10044. The one or more vents in the airway compartment 1004 are disposed in the sidewall structure 10042 (e.g., Figure 2 (As shown). The one or more vents defined in the sidewall structure 10042 are indicated by reference numeral 10244. The air duct compartment 1004 also includes a duct 1007. One end of the duct 1007 may be fixed to an opening defined in the sidewall structure 10042 and may extend from the opening along the transverse axis T-T'. The air duct compartment 1004 may define a lateral exhaust configuration of the switch cabinet 1000. The other end of the duct 1007 opposite to the end connected to the sidewall structure 10042 defines one or more vents 10044. A filter element 10046 is fixed to each of the one or more vents 10044 defined in the duct 1007.

[0041] In one embodiment, the switch cabinet 1000 of this disclosure, equipped with filter element 10046, ensures that the cooling air flowing into the switch cabinet 1000 is free of foreign particles such as dust and chemical fumes. The inclusion of filter element 10046 in the switch cabinet 1000 expands its application range beyond cleanroom applications. The configuration of the air duct compartment 1004 of the switch cabinet 1000 ensures that filter element 10046 is easy to remove and insert. Therefore, the switch cabinet 1000 of this disclosure ensures that filter element 10046 is easy to maintain.
