[0024] The embodiment of the present invention discloses a temporary isolation device for a low-voltage power distribution cabinet, which can be temporarily installed in the cabinet of the low-voltage power distribution cabinet, and isolate the waiting operation position in the low-voltage power distribution cabinet and the power supply adjacent to the waiting operation position, leaving a safe operating space for the staff, effectively protecting the staff from the threat of adjacent power supplies when performing maintenance and inspection work on the low-voltage power distribution cabinet, and improving the safety of the staff.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-2 An embodiment of the present invention provides a temporary isolation device for a low-voltage distribution cabinet, including a support member and an insulating plate 103; the length of the support member is adjustable, and is used to support between the inner walls on both sides of the cabinet of the low-voltage distribution cabinet; the insulating plate 103 is installed on the support member, and is used to be arranged between a position to be operated and a power supply adjacent to the position to be operated.

[0027] In the above-mentioned temporary isolation device for a low-voltage distribution cabinet, the support member can be supported between two opposite side walls in the cabinet body, so as to be temporarily installed in the cabinet body of the low-voltage distribution cabinet, and the insulating plate 103 isolates the operating position in the low-voltage distribution cabinet and the power supply adjacent to the operating position, leaving a safe operating space for the staff, effectively protecting the staff from the threat of adjacent power supplies when performing maintenance and inspection work on the low-voltage distribution cabinet, thereby improving the safety of the staff.

[0028] In one embodiment, the support member includes a telescopic rod, and the telescopic rod includes a main body and a telescopic portion inserted in the main body. In order to adapt to the distance between two opposite inner walls in different cabinets, the telescopic portion of the support rod is configured to be able to be positioned at any extension size. Of course, the telescopic portion also needs to be able to be retracted into the main body to facilitate disassembly.

[0029] The insulating plate 103 is installed on the main body, and the installation position of the insulating plate 103 on the main body can be adjusted to facilitate adjusting the insulating plate 103 to a suitable position to accurately isolate the operating position in the low-voltage distribution cabinet and the power supply adjacent to the operating position.

[0030] In order to ensure that the temporary isolation device is stably installed in the cabinet, two support members are provided and arranged in parallel.

[0031] The support member can be set as a pneumatic push rod 102; accordingly, the two support members are connected to different air sources, or the two support members are connected to the same air source. The air source uses a manual air bag 104, which saves costs and is convenient for users to operate. The air source can also use a pneumatic pump, and those skilled in the art do not limit the type of air source.

[0032] In another embodiment, the telescopic portion is configured as a rack, and the rack can be driven by an output gear of a driving motor.

[0033] In order to improve the insulation performance, insulating pads 101 for abutting against the inner wall of the low-voltage distribution cabinet are installed at both ends of the support. In use, the insulating pads 101 at both ends of the support are respectively pressed against two opposite inner walls of the cabinet. In the scheme where the support adopts a pneumatic push rod 102, the insulating pad 101 is installed at one end of the main body away from the telescopic part, and the insulating pad 101 is installed at the end of the telescopic part that protrudes outward.

[0034] The insulating plate 103 may be a polymethyl methacrylate plate or a polycarbonate plate. The present embodiment does not limit the type of the insulating plate 103 , and only needs to ensure its insulation performance.

[0035] The structure of the low-voltage power distribution cabinet is complex. Take the maintenance of the vertically arranged switches in the low-voltage power distribution cabinet as an example. Each switch corresponds to one power supply. When the switch in the middle is repaired, both the upper and lower sides are close to the power supply, and the power supply equipment close to the two sides cannot be powered off to avoid the expansion of the accident. In this case, two temporary isolation devices provided in this embodiment can be used, so that the insulating plate 103 of one temporary isolation device isolates the switch to be repaired from the switch on the upper side, and the insulating plate 103 of the other temporary isolation device isolates the switch to be repaired from the switch on the lower side. When repairing the upper or lower switch, if only one side of the switch to be repaired has a live switch, only one temporary isolation device provided in this embodiment can be used.

[0036] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0037] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
