Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a fault alarm device for a power distribution cabinet. 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 occasions with relatively dispersed loads and fewer circuits. The motor control center is used in occasions with concentrated loads and more circuits. They distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] In a Chinese patent, a distribution cabinet fault alarm device is disclosed, and its patent number is 202020741118.0. In this patent, a first fault detector, a second fault detector, a receiver, a first controller, an electrical switch, a second controller and an alarm are set. When the first fault detector or the second fault detector detects a fault, the signal is transmitted to the receiver, and the receiver organizes the signal and transmits it to the first controller. The first controller receives the signal, controls the electrical switch to disconnect the circuit, and transmits the signal to the second controller at the same time. The second controller controls the alarm to start, thereby transmitting a fault alarm signal, allowing maintenance personnel to carry out maintenance, respond quickly, and disconnect the circuit in time. At the same time, it can also avoid the continued use of the circuit when a fault occurs, causing electrical damage, and causing losses and dangerous faults.

[0004] However, in the actual use of distribution cabinets, existing distribution cabinets often do not have the function of alarming when the internal temperature of the distribution cabinet is abnormal. When the distribution cabinet is used for a long time or in a high temperature environment, a large amount of heat will be generated inside the main body of the distribution cabinet, and the existing distribution cabinet is not convenient for users to perform heat dissipation protection on the inside. Long-term high temperature will cause the equipment in the main body of the distribution cabinet to fail or even be damaged, and the safety is low. Utility Model Content

[0018] Second, the utility model provides a warning light. When the temperature inside the main body of the power distribution cabinet rises to a dangerous value, the temperature sensing probe transmits a signal to the warning light, causing the warning light to light up to remind the user. By providing a temperature sensing probe, the temperature inside the main body of the power distribution cabinet can be monitored in real time. When the temperature exceeds the dangerous value, a signal is sent to the warning light and the alarm, causing them to light up and make a sound to remind the user. BRIEF DESCRIPTION OF THE DRAWINGS
