Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, and more specifically to a power distribution cabinet with temperature monitoring and wireless early warning. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits. There are multiple accessories and centralized lines inside the distribution cabinet. After long-term use, the internal temperature will become higher and higher. If the internal high temperature cannot be handled in time, it is easy to damage the internal accessories of the distribution cabinet. Therefore, a temperature monitoring wireless early warning distribution cabinet is needed.

[0003] For example, the patent document with application number 202320766607.5 discloses a distribution cabinet with temperature monitoring and wireless early warning. The distribution cabinet with temperature monitoring and wireless early warning performs real-time remote monitoring of the temperature of the distribution cabinet through a temperature sensor and a display screen, and activates the alarm according to the temperature. When in use, pull the handle to move the main body of the distribution cabinet along the sliding groove through the sliding bar, thereby pulling the main body of the distribution cabinet out of the protective outer shell. However, in the event that the temperature rises too high or even causes a fire, the harmful gases and smoke generated in the distribution cabinet cannot be remotely monitored in real time. In this case, rashly opening the distribution cabinet by manually pulling the handle will cause the risk of poisoning, burns, and electric shock. In this case, the high temperature in the distribution cabinet cannot be handled in time, further causing economic losses and creating dangers.

[0004] Therefore, how to provide a temperature monitoring and wireless early warning distribution cabinet, when the temperature rises too high or even causes a fire, to obtain real-time data on harmful gases and smoke generated in the distribution cabinet to provide reminders, and to push out the main body of the distribution cabinet through an electric telescopic rod to avoid poisoning, burns and electric shock caused by manual pulling by the operator, so as to achieve safe and timely processing of high temperatures in the distribution cabinet is a problem that technical personnel in this field urgently need to solve.
