Problems solved by technology

[0003] The current high and low voltage switch cabinets are only opened and closed by a single switch when operating the cabinet door, which makes it easy for non-staff to open it, resulting in electric shock accidents, which are highly dangerous. To protect the high and low voltage switchgear, a leakage alarm will be installed in the cabinet to detect the leakage in the cabinet. Cut off the power, and then open the cabinet door for maintenance. The current operational defect is that the high and low voltage switch cabinet cannot be powered off while the cabinet door is open, so that the pre-order operation takes a long time when the cabinet is repaired, and the first step cannot be performed. Immediate maintenance may easily lead to fire in the cabinet due to high temperature caused by electric leakage, resulting in loss of economic property

Embodiment 1

[0028] refer to Figure 1-Figure 3 , a high and low voltage switchgear for safe operation, including a cabinet body 1, a cabinet door 2 hinged on the side wall of the cabinet body 1, a protection mechanism for protecting the cabinet body 1 is provided on the cabinet door 2, and the protection mechanism includes a cabinet door 2 Inside the strip-shaped chamber 3, the inner wall of the strip-shaped chamber 3 is slidably connected with two slide plates 4, and the side walls of the two slide plates 4 that are far away from each other are elastically connected with the inner wall of the strip-shaped cavity 3 through a spring 5, and the sides of the two slide plates 4 that are close to each other The walls are fixedly connected with two fixed plates 6, the side walls of the two fixed plates 6 are rotatably connected with a connecting rod 7, and the side walls of the connecting rod 7 are fixedly connected with a first gear 8, and the side wall of the cabinet body 1 close to the strip ...

Embodiment 2

[0038] refer to Figure 4-Figure 5 , different from Embodiment 1, the cabinet door 2 is provided with a power-off mechanism for power-off in the cabinet body 1, and the power-off mechanism includes two chutes opened on the side wall of the cabinet body 1 located in the cabinet body 1 19. The inner walls of the two chute 19 are rotatably connected with a reciprocating lead screw 20, and the side wall of the reciprocating lead screw 20 is threadedly connected with a slider 21. One side wall of the slider 21 is slidingly connected with the inner wall of the chute 19, and the two chute 19 Push switches 22 matching the slider 21 are mounted on the inner walls, and the two push switches 22 are respectively coupled and connected to the current input end and the output end.

[0039] Further, when the two reciprocating screw screws 20 rotate to make the two sliders 21 slide back and forth, the two ends of the two push switches 22 will be intermittently squeezed by the sliders 21 that c...

Embodiment 3

[0044] refer to Figure 6-Figure 8 , different from Embodiment 1, the cabinet 1 is provided with a cleaning mechanism for cleaning the alarm 17 and the warning light 18, and the cleaning mechanism includes two annular grooves 28 provided at the upper end of the cabinet 1, and sliding in the annular groove 28 A toothed ring 29 is connected, the upper end of the toothed ring 29 is fixedly connected with an arc-shaped plate 30 , and the inner wall of the arc-shaped plate 30 is fixedly connected with a plurality of bristles 31 .

[0045] The cabinet body 1 is provided with a transmission mechanism that drives the gear ring 29 to rotate. The transmission mechanism includes a drive rod 32 that is rotatably connected to the side wall of the cabinet body 1. The side walls of the drive rod 32 run through the inner walls of two annular grooves 28 respectively. The drive rod 32 is located at the two sides. The side walls in each annular groove 28 are all fixedly connected with two third ...

Abstract

The invention discloses a high and low voltage switchgear for safe operation, which comprises a cabinet body, the side wall of the cabinet body is hinged with a cabinet door, the cabinet door is provided with a protection mechanism for protecting the cabinet body, and the protection mechanism includes an opening In the strip-shaped cavity in the cabinet door, the inner wall of the strip-shaped cavity is slidably connected with two slide plates, the side walls of the two slide plates away from each other are elastically connected to the inner wall of the strip-shaped cavity by springs, and the two slide plates are close to each other The side walls of the two fixed plates are fixedly connected with two fixed plates, the side walls of the two fixed plates are rotatably connected with connecting rods, the side walls of the connecting rods are fixedly connected with the first gear, and the side walls of the cabinet close to the bar-shaped cavity There are two card slots. In the present invention, the protection mechanism is provided so that the cabinet door can only be opened by turning two hands clockwise at the same time, which avoids setting a single switch on the cabinet door, which makes it easy for non-workers to open it, thereby causing electric shock accidents.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a high and low voltage switchgear for safe operation. Background technique [0002] The high and low voltage switchgear is a device connected to high voltage or low voltage cables. [0003] The current high and low voltage switch cabinets are only opened and closed by a single switch when operating the cabinet door, which makes it easy for non-staff to open it, resulting in electric shock accidents, which are highly dangerous. To protect the high and low voltage switchgear, an electric leakage alarm will be installed in the cabinet to detect the leakage in the cabinet. Cut off the power, and then open the cabinet door for maintenance. The current operational defect is that the high and low voltage switchgear cannot be powered off while the cabinet door is open, so that the pre-order operation takes a long time when the cabinet is repaired, and the first step cannot ...
