Detailed Embodiments

[0017] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0018] An anti-misoperation high-voltage switchgear for a photovoltaic power station, as Figures 1 - 3As shown in the figure, it includes a connection bracket 1, a housing 2, a fixed connection bracket 20, a fixing bracket 21, a button 22, an alarm 23, a fan 24, an opening and closing door 3, a connecting rotating bracket 30, a cylinder 4, a guiding support plate 5, a grounding wire 6, a high-voltage switchgear cabinet 7 and rollers 8. The upper side of the connection bracket 1 is connected to the housing 2. The front right side of the housing 2 is connected to the fixed connection bracket 20. The upper right side of the housing 2 is connected to the fixing bracket 21. The button 22 is slidably connected to the front part of the fixing bracket 21. The alarm 23 is connected to the right side of the fixing bracket 21. Two left and right fans 24 are connected to the upper part of the housing 2. The opening and closing door 3 is rotatably connected to the fixed connection bracket 20. A handle is provided on the front side of the left part of the opening and closing door 3, which is convenient for holding and opening. An air-permeable net is provided on the upper part of the opening and closing door 3, which is convenient for air permeability and heat dissipation. The right part of the opening and closing door 3 is connected to the connecting rotating bracket 30. The connecting rotating bracket 30 contacts the button 22. The lower part of the connection bracket 1 is connected to the cylinder 4. The telescopic end of the cylinder 4 is connected to the guiding support plate 5. The grounding wire 6 is connected to the front side of the connection bracket 1. The high-voltage switchgear cabinet 7 is placed on the upper side of the guiding support plate 5. Eight rollers 8 are rotatably connected to the upper part of the connection bracket 1.

[0019] When using this device, first place the connection bracket 1 in the placement area of the high-voltage switchgear cabinet 7 so that the grounding wire 6 contacts the ground. When a fault occurs in the electrical system, the grounding wire 6 can provide a low-impedance path to allow the current to flow to the ground, thus avoiding the generation of dangerous voltages inside the equipment. Then place the high-voltage switchgear cabinet 7 inside the housing 2 so that the high-voltage switchgear cabinet 7 contacts the rollers 8 and the guiding support plate 5. Then move the high-voltage switchgear cabinet 7 backward to drive the rollers 8 to rotate, so that the high-voltage switchgear cabinet 7 is located inside the housing 2. Then start the cylinder 4 to drive the guiding support plate 5 to move upward, which can facilitate the placement of the high-voltage switchgear cabinet 7. The operation is simple, saving manpower and improving the convenience of using this device. After the placement is completed, hold the handle to rotate and close the opening and closing door 3, drive the connecting rotating bracket 30 to rotate, so that the connecting rotating bracket 30 contacts the button 22 on the fixing bracket 21, and then turn on the alarm 23. When a non-staff member directly opens the opening and closing door 3, it drives the connecting rotating bracket 30 to rotate, so that the connecting rotating bracket 30 no longer contacts the button 22, triggering the alarm 23 to sound an alarm, which can thus sound an alarm when a non-staff member opens the opening and closing door 3, reminding the non-staff member to pay attention to safety and avoiding safety accidents caused by non-staff members accidentally touching the high-voltage switchgear cabinet 7. When the staff needs to repair the high-voltage switchgear cabinet 7, the alarm 23 can be turned off first, and then the opening and closing door 3 can be rotated and opened to repair the high-voltage switchgear cabinet 7, and air permeability and heat dissipation are carried out through the air-permeable net.
