Description

Technical Field

[0001] The utility model relates to the technical field related to bus duct monitoring, in particular to an intelligent plug-in box for a bus duct. Background Art

[0002] Bus duct is a power transmission device that is often used for long-distance power transmission and distribution. It is usually made of metal materials and has certain conductivity and heat dissipation properties. Bus duct can be installed inside buildings, factories, construction sites and other various places to connect electrical equipment, machines and facilities.

[0003] A plug-in box is a type of power distribution equipment that is commonly used to connect and distribute power. It is widely used in industrial, commercial, and residential areas. Its main function is to lead out a safe and convenient power output interface on the bus duct, provide safe and reliable power supply for various electrical equipment, and realize the control and management of electric energy. In terms of bus duct applications, plug-in boxes play an important role. Plug-in boxes can provide flexibility and convenience, making it easier to connect the interface and power supply of electrical equipment. Through the plug-in box, power can be easily connected and distributed without complicated cable wiring. Secondly, the plug-in box has good safety performance, which can prevent electrical problems such as current overload and short circuit, ensuring the safety of equipment and personnel. In addition, the plug-in box also has an adjustable circuit breaker or fuse to achieve control and protection of power supply.

[0004] However, as a power line node, the plug-in box also has the problems of general circuit nodes. The total cross-section of the plug-in row is thicker than the line conductor, and the heat dissipation is worse, resulting in electrical structural weaknesses. During use, the contact resistance at the connection between the plug-in box and the bus duct increases due to improper use, excessive load, material aging, reduced contact surface pressure or surface aging, etc., causing the temperature rise of the contact point to increase. When the temperature rise exceeds the normal working range, it is very likely to cause the bus insulation to decrease or the power supply to be missing, causing major problems in the power supply system, causing equipment damage and even power outages. In addition, the bus duct is generally installed at a high position above the ground, and some large places may install more than a dozen plug-in boxes, which greatly increases the difficulty of plug-in box maintenance in terms of both height and number. Therefore, intelligent plug-in boxes with real-time monitoring and electrical data upload functions came into being. Utility Model Content
