[0046] Example 1

[0047] Please refer to Figure 1-2 , a novel high-voltage switch cabinet, comprising a meter cabinet 100;

[0048] A metering cabinet 100, wherein a power supply copper bus is arranged in the metering cabinet 100;

[0049] The incoming line cabinet 110 is arranged on one side of the metering cabinet 100, and the top of the incoming line cabinet 110 is connected with an incoming line copper bus 210 and a first insulating shell 220;

[0050] The outgoing line cabinet 120 is arranged at the other side of the metering cabinet 100, and the top of the outgoing line cabinet 120 is connected with an outgoing line copper bus 310 and a second insulating shell 320;

[0051] The incoming line protection box 200 is arranged on the top surface of the incoming line cabinet 110, and the incoming line copper bus 210 and the first insulating shell 220 are located in the incoming line protection box 200;

[0052] The outgoing line protection box 300 is arranged on the top surface of the outgoing line cabinet 120, and the outgoing line copper bar 310 and the second insulating shell 320 are located in the outgoing line protection box 300; wherein:

[0053] The top surfaces of the incoming line protection box 200, the outgoing line protection box 300 and the metering cabinet 100 are all on the same horizontal plane; the power copper busbar, the incoming line copper busbar 210 and the outgoing line copper busbar 310 are electrically connected via a connecting copper busbar.

[0054] Through the above structural design, the first insulating shell 220 and the second insulating shell 320 are respectively used to prevent the current leakage of the incoming copper bus 210 and the outgoing copper bus 310, and play a role in insulation protection. The first insulating shell 220 and the second insulating shell 320 are both 10KV plug heads.

[0055] The incoming line cabinet 110 is arranged on the left side of the metering cabinet 100, and the outgoing line cabinet 120 is arranged on the right side of the metering cabinet 100. The incoming line cabinet 110 and the outgoing line cabinet 120 can be spliced ​​with the metering cabinet 100. The incoming line protection box 210 and the outgoing line protection box 310 provide protection space for the incoming line copper bus 220 and the outgoing line copper bus 320 respectively. The incoming line protection box 210 and the outgoing line protection box 310 are respectively arranged on the incoming line cabinet 110 and the outgoing line cabinet 120. The incoming line copper bus 220 and the outgoing line copper bus 320 are both located in the first insulating shell 220 and the second insulating shell 320, so as to obtain better protection and insulation effect. The total height of each box is consistent, which is convenient for installation and neat appearance, can prevent the copper bus from being exposed to the air, and ensure good conductivity.

[0056] Specifically, an ammeter 400 and an indicator light 500 are disposed in front of the incoming line protection box 200 and the outgoing line protection box 300 .

[0057] An ammeter 400 and an indicator light 500 are also provided on the front side walls of the incoming line protection box 210 and the outgoing line protection box 310, which are helpful for detecting the operation of the high-voltage switch cabinet.

[0058] like Figure 3-5 As shown, specifically, a pressure relief and explosion-proof panel is provided on at least one side of the incoming line protection box 200 and the outgoing line protection box 300 .

[0059] The pressure relief explosion-proof panel allows the new high-voltage switchgear to release pressure outward when it is subjected to pressure impact, thereby protecting internal components from damage and avoiding the trouble of subsequent maintenance and replacement.

[0060] like Figure 3-5 As shown, specifically, the pressure relief explosion-proof panel includes a panel body 620 and a pressure relief plate 630, the panel body 620 is provided with at least one through hole 650, the pressure relief plate 630 covers the outside of the through hole 650, the lower end of the pressure relief plate 630 is installed on the panel body 620 through a first fastener 680, and the upper end of the pressure relief plate 630 is installed on the panel body 620 through a second fastener 660, and the locking force of the second fastener 660 is less than the locking force of the first fastener 680.

[0061] Through the above-mentioned structural design, the pressure relief and explosion-proof panel is set to buffer and relieve the pressure in the cabinet, which is beneficial to prevent the accumulation of pressure in the cabinet and prevent explosion; a rectangular through hole 650 is set on the panel body 620, and the lower end of the pressure relief plate 630 is threadedly connected to the panel body 620 through the first fastener 680, and the upper end of the pressure relief plate 630 is threadedly connected to the panel body 620 through the second fastener 660, and then the pressure relief plate 630 covers the through hole 650. Since the locking force of the second fastener 660 is weaker than the locking force of the first fastener 680, when the air pressure rushes out from the inside, it can rush out through the through hole 650. Since the pressure relief plate 630 has a weak locking force on the top, the second locking member 660 will bounce open due to the pressure, and the pressure relief plate 630 opens at an angle to release the internal pressure.

[0062] Specifically, a plurality of ventilation grooves 610 are disposed on the front sides of the panel body 620 and the pressure relief plate 630 .

[0063] Through the above-mentioned structural design, the air grooves 610 are arranged in a matrix on the front of the panel body 620 and the pressure relief plate 630, and their shape is an oblong slot with the opening facing upward. The air grooves 610 are distributed in a rectangular array, which can efficiently and scientifically disperse the heat evenly, which is beneficial to the heat dissipation efficiency. The air grooves 610 are used to dissipate heat for the new high-voltage switchgear, which ensures the performance of the new high-voltage switchgear and extends its service life.

[0064] Example 2

[0065] The new high-voltage switchgear provided in Example 1 is further optimized. Specifically, Figure 2 As shown, the first fastener 680 is a metal screw and the second fastener 660 is a plastic screw.

[0066] Through the above structural design, the locking force of the plastic screw is weaker than that of the metal screw, which will cause the difference in the upper and lower locking forces. Therefore, when the air pressure rushes out from the inside, it can rush out through the through hole 650. Since the pressure relief plate 630 has a weak locking force on the top, the second locking member 660 will bounce open due to the pressure, and the pressure relief plate 630 will open at an angle to release the internal pressure.

[0067] Example 3

[0068] The new high-voltage switchgear provided in Example 1 or 2 is further optimized, such as Figure 3-5 As shown, the pressure relief explosion-proof panel includes a filter screen 640 , and the filter screen 640 is arranged on the back side of the pressure relief plate 630 and the back side of the panel body 620 .

[0069] The above structural design is mainly used to measure the temperature environment and control it within a suitable range to monitor the space temperature in real time.

[0070] Specifically, the position of the filter screen 640 corresponds to the position of the air-permeable groove 610 .

[0071] Through the above structural design, the filter screen 640 is respectively arranged on the back side of the panel body 620 and the back side of the pressure relief plate 630 and corresponds to the air permeable groove 610, which is helpful to prevent insects from entering the interior.

[0072] Specifically, Figure 3 As shown, the pressure relief explosion-proof panel also includes a cutting line 670 , which is arranged on the lower end of the pressure relief plate 630 .

[0073] Through the above structural design, in order to prevent excessive internal pressure from causing the pressure relief plate 630 to be excessively bent without breaking during pressure relief, the cutting line 670 is conducive to the pressure relief plate 630 to break under excessive pressure, which is convenient for replacement.

[0074] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model.
