Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment, and in particular to a moisture-proof and condensation-proof Chinese-style box-type transformer switch cabinet. Background Art

[0002] Condensation is the phenomenon that when the temperature drops below the dew point temperature, the moisture in the air condenses into water droplets; condensation will seriously affect the safe operation of electrical equipment. Whether condensation occurs depends on the indoor temperature, the temperature inside the cabinet, the relative humidity and the dew point temperature. For Chinese box-type transformer switchgear (hereinafter referred to as switchgear), the switchgear is usually installed outdoors. If it is in a relatively dry climate, it is okay. Once it is installed in a humid area, when the humidity inside the switchgear is high, condensation is likely to occur. This phenomenon is called condensation.

[0003] At present, the moisture-proof and anti-condensation devices used in switch cabinets are mainly condensation sensors and heating devices. However, condensation sensors are prone to failure and lack long-term working stability, while heating devices will increase the temperature inside the switch cabinet to a certain extent, causing the metal pins of electrical components to oxidize, reducing the performance of electrical components, and failing to utilize the heat dissipation of the switch cabinet and the working stability of the electrical equipment inside the cabinet.

[0051] The slide rail 500 is vertically connected to the outer wall of the first side plate 110, and the top end of the slide rail 500 is higher than the first through hole; the regeneration chamber 400 includes a first outer plate 410, a top wall 430 and a bottom wall 420; the first outer plate 410 is provided with a slide groove 412; the slide rail 500 is embedded in the slide groove 412; the first outer plate 410 is in close contact with the outer wall of the first side plate 110 and can slide relative to each other; the first outer plate 410 is also provided with a fourth notch 411; the top wall 430 is provided with a third slot 433 near the first outer plate 410; the third baffle is vertically movably embedded in the third slot 433 and in close contact with the inner wall of the first outer plate 410.

[0053] The maximum mesh diameters of the first gauze 212, the second gauze 222, the third gauze 232, the fifth gauze 422 and the sixth gauze 432 are all smaller than the diameter of the silica gel particles.

[0054] The bottom wall 420 can contact the top of the fan cover 600, and the bottom wall 420 and the fan cover 600 are opposite in the vertical direction; when the bottom wall 420 contacts the top of the fan cover 600, the fourth through hole 340 is opposite to the upper part of the fourth notch 411 (this is the lowest position of the regeneration chamber 400); when the regeneration chamber 400 slides to the highest position, the lower part of the fourth notch 411 is opposite to the third through hole 330.

[0055] The moisture-proof and condensation-proof Chinese-style box-type transformer switch cabinet is provided with a storage chamber 200, and the first inner plate 210 of the storage chamber 200 is provided with a first gauze 212, the second inner plate 220 is provided with a second gauze 222, and the third inner plate 230 is provided with a third gauze 232; silica gel particles are stored in the storage chamber 200, and the silica gel particles have excellent water absorption and can dry the air in the cabinet in real time, thereby realizing the moisture-proof function in the cabinet. The dry air in the cabinet can better prevent condensation from occurring in the cabinet.

[0056] The moisture-proof and condensation-proof Chinese-style box-type transformer switch cabinet proposed in the present invention has no sensors and heating devices arranged inside the cabinet (the resistance wire is arranged outside the cabinet), thereby avoiding the failure of the moisture-proof function due to sensor failure, and also avoiding the adverse effects of the heating device on the electrical components of the cabinet; the technical features of the present invention are all realized through the structure, without the aid of any electrical components such as sensors, and have good working stability and high practicality.

[0057] The moisture-proof and condensation-proof Chinese-style box-type transformer switch cabinet proposed in the present invention can also realize the regeneration of silica gel particles (i.e., reheating the silica gel particles that have absorbed moisture to evaporate the absorbed moisture, so that the silica gel particles have the ability to dry air again). Specifically, when the silica gel particles in the storage chamber 200 need to be regenerated, the second baffle and the third baffle are pulled out, and the second through hole 242 and the fourth through hole 340 are connected; at this time, the regeneration chamber 400 is located at the lowest position, and the fourth notch 411 is connected with the fourth through hole 340, then the silica gel particles in the storage chamber 200 will enter the regeneration chamber 400 through the second through hole 242, the fourth through hole 340 and the fourth notch 411 under the action of gravity; when the silica gel particles are transferred, the third baffle is inserted into the lowest position to close the fourth notch 411, and then the axial flow fan and the resistance wire are started, and the axial flow fan blows hot air into the regeneration chamber 400 to heat the silica gel particles in the regeneration chamber 400, thereby regenerating the silica gel particles.

[0058] After the regeneration of the silica gel particles is completed, the axial flow fan and the resistance wire are turned off, and the regeneration chamber 400 is moved vertically upward along the slide rail 500 to the lower part of the fourth notch 411 and directly opposite to the third through hole 330, and then the third baffle and the first baffle are pulled out, and the third through hole 330 and the first through hole are connected. Under the action of gravity, the silica gel particles in the regeneration chamber 400 enter the storage chamber 200 from the fourth notch 411, the third through hole 330 and the first through hole in turn. After the transfer of the silica gel particles is completed, the first baffle and the third baffle are inserted again. At this point, the whole process of regeneration of the silica gel particles is completed.

[0059] By regenerating the silica gel particles, the silica gel particles can be reused many times, saving operating costs.

[0060] In addition, if attached Figure 3 As shown, the angle formed by the bottom plate 250 and the fourth inner plate 240 is an acute angle. In the present embodiment, the angle formed by the top plate 260 and the fourth inner plate 240 is 10°-80° (preferably 45°). This arrangement makes it easier for the silica gel particles to roll from the storage chamber 200 into the regeneration chamber 400.

[0061] In addition, if attached Figure 2 and attached Figure 3 As shown, the structures and sizes of the first baffle, the second baffle and the third baffle are consistent.

This arrangement makes it easy to pull the first baffle out of and insert it into the first slot.

[0063] The second baffle includes a second main board 322, a second sub-board 320 and a second handle 321; the second sub-board 320 is perpendicular to the second main board 322 and connected to one end of the second main board 322; a side of the second sub-board 320 away from the second main board 322 is connected to the second handle 321; the second main board 322 can be embedded in the second slot, and the second sub-board 320 can be in contact with the outer wall of the first inner board 210. This arrangement makes it easy to pull the second baffle out of and insert it into the second slot.

[0064] The third baffle includes a third main board 453, a third sub-board 451 and a third handle 452; the third sub-board 451 is perpendicular to the third main board 453 and connected to one end of the third main board 453; a side of the third sub-board 451 away from the third main board 453 is connected to the third handle 452; the third main board 453 can be embedded in the third slot 433, and the third sub-board 451 can be in contact with the outer surface of the top wall 430. This arrangement makes it easy to pull the third baffle out of and insert it into the third slot 433.

[0065] At the same time, if attached Figure 1 As shown, the cabinet further includes a second side panel 120; the second side panel 120 intersects with the first side panel 110, and the second side panel 120 is provided with a movable door 130. The movable door 130 is provided with a ventilation hole 140. It is more convenient for maintenance personnel to manually pull out and insert the first baffle and the second baffle.

[0066] In addition, if attached Figure 2 and attached Figure 4 As shown, the cross-section of the slide rail 500 includes a circle and a rectangle. Such a cross-section is more conducive to the relative sliding between the slide groove 412 and the slide rail 500. The outer wall of the slide rail 500 is coated with lubricating oil (not shown), so that the vertical sliding of the regeneration chamber 400 is smoother.

[0067] In addition, if attached Figure 4 As shown, a spring 350 is also connected between the first main board and the inner wall of the second inner board 220; a spring 350 is also connected between the second main board 322 and the inner wall of the second inner board 220; and a spring 350 is also connected between the third main board 453 and the inner wall of the bottom wall 420.

[0068] By providing the spring 350 , the first baffle, the second baffle and the third baffle can realize a rebound function, making the pulling out and inserting operations thereof more convenient.

[0070] The third door-shaped rod 440 is connected to the inner wall of the first outer panel 410 , and a side of the third baffle plate away from the first outer panel 410 contacts the third door-shaped rod 440 .

[0071] By providing the first door-shaped rod, the second door-shaped rod 270 and the third door-shaped rod 440, the first baffle and the second baffle are always attached to the inner wall of the fourth inner plate 240, and the third baffle is always attached to the inner wall of the first outer plate 410. The structure is more compact and can prevent the leakage of silica gel particles.

[0072] As attached Figure 5 and attached Figure 6 As shown, in another embodiment of the moisture-proof and condensation-proof Chinese-style box-type transformer switch cabinet, the bottom wall 420 is inclined toward the first outer panel 410. At this time, the top of the fan sleeve 600 tube can contact the side wall of the regeneration chamber 400. This arrangement is to allow the silica gel particles in the regeneration chamber 400 to roll more easily into the storage chamber 200.

[0073] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
