Integrated node ring main unit for emergency power supply

Abstract

The invention discloses an integrated node ring main unit for an emergency power supply, which comprises an emergency power supply integrated node switch cabinet, a top expansion splicing cabinet bus and an incoming line PT cabinet. Two ends of the top expansion splicing cabinet bus are respectively assembled and connected with stainless steel gas tanks of the emergency power supply integrated node switch cabinet and the incoming line PT cabinet; and the stainless steel gas tanks of the incoming line PT cabinet are formed by sequentially fixing a top expansion sleeve, a lap joint copper bar, a load switch, a PT bus and an inlet wire sleeve through screws and then assembling. The emergency power supply integrated with node switch cabinet stainless steel gas tank is formed by sequentially locking a top expansion sleeve, a lap joint copper bar, a load switch, a bus and a node switch sleeve and fixing an aviation plug cable device with screws, and then assembling, and the segmentation and conduction of a conductive loop are operated through a two-station load switch mechanism and a three-station load switch mechanism respectively. Each functional unit is independent, the internal electric field distribution is uniform, the insulating property is good, and the safety is high; and a novel aviation plug plugging and unplugging locking device is also arranged, so that the cable is convenient, rapid and safe to plug and unplug.

Description

technical field [0001] The invention relates to the technical field of indoor high-voltage power distribution equipment, in particular to an integrated node ring network cabinet for emergency power supply. Background technique [0002] The existing emergency power supply integration node ring network cabinet is mostly used to "combine two into one" with the PT cabinet, the layout is messy, the internal electric field is unevenly distributed, the insulation performance is not good, and the operation is inconvenient. In case of emergency, it is difficult to get power, plug and unplug the aviation plug cable, and the procedures are cumbersome. At present, there have been many unsafe accidents in this type of cabinet on the market. Contents of the invention [0003] The object of the present invention is to provide an integrated node ring network cabinet for emergency power supply to solve the problems in the prior art above. The PT incoming cabinet and the integrated node rin...
