Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of emergency socket, in particular to a low-voltage fast emergency socket. BACKGROUND

[0002] In the process of power system operation, when power is cut off due to failure or maintenance, in order to meet the basic needs of users, some emergency equipment such as low-voltage fast emergency socket, emergency power generator truck, etc. are usually used. The low-voltage fast emergency socket is mainly used in the scene of rescue and disaster relief, important user power supply, transformer load transfer, etc. It is installed on the power distribution cabinet to quickly connect the emergency power supply and the power supply end, and can achieve three-second connection and five-second power-on. The existing low-voltage power distribution cabinet has different models and sizes, and there are many types, which need to be matched with different types of low-voltage fast emergency socket, resulting in poor universality of the low-voltage fast emergency socket.

[0003] The lead-out hole of the power distribution cabinet is generally arranged on the bottom surface or side surface of the cabinet body, and the busbar (wire distribution plate) inside the power distribution cabinet is commonly arranged vertically. The lead-out hole of the power distribution cabinet is usually arranged on the bottom surface or side surface, and the socket 1 has A-shaped and B-shaped. The mounting plate 2 of the A-shaped socket (see Figure 1 ) is arranged in a straight line with the socket 1, and the mounting plate 2 of the B-shaped socket (see Figure 2 ) is arranged vertically at 90° with the socket 1. For the A-shaped socket, it can be directly matched with the vertically arranged busbar, but for the B-shaped socket, due to the limitation of the busbar space and the lead-out hole of the power distribution cabinet, the power distribution cabinet door cannot be closed after the plug is connected. If it is used outdoors, it will cause safety risks. For the above situation, if you want to match the socket, you need to remove the busbar of the power distribution cabinet and reengineer and install it, which is a large amount of work and affects work efficiency, and causes damage to the emergency equipment.

[0004] Some power distribution cabinets are provided with a panel on the cabinet door, and the plug can be directly plugged into the panel, but this power distribution cabinet can only be used indoors. For outdoor applications, rain and other weather conditions can cause water to enter the socket and cause a short circuit, making it impossible to use. Moreover, if the cable is bent 90° directly from the panel, long-term use will cause insulation damage to the cable.

[0005] In addition, for the A-shaped socket, the mounting plate of the socket 1 usually has only one mounting hole 3. When the cable connected by the plug is too long, if it is pulled by external force, it will cause the socket 1 to become loose and thus be disconnected from the power supply, making the power supply process unstable, affecting work progress, and causing serious losses.
