Technical Field
[0001] The utility model relates to the technical field of ring network cabinet accessories, in particular to a ring network cabinet fault monitoring and control device. Background Art
[0002] The ring main unit is a type of electrical transmission and distribution equipment. Its core part uses load switches and fuses. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. During operation, the ring main unit will monitor parameters such as current, voltage, and temperature through various monitoring devices. When a fault occurs, parameters such as current, voltage, and temperature will fluctuate greatly, so the monitoring device will automatically shut down the circuit and remind the staff to carry out maintenance.
[0003] The existing fault detection and control device of the ring network cabinet requires multiple instruments to monitor parameters such as current, voltage, temperature, humidity, etc. The sensors are placed on the circuit or in the ring network cabinet, but the instrument displaying the parameters needs to be installed on the cabinet door for the convenience of the staff to view. Due to the large number of instruments, multiple square or round holes need to be opened on the surface of the ring network cabinet for installing mechanical instruments or electronic instruments. The distribution positions of instruments in different types of ring network cabinets are different, resulting in more bending and punching molds during the production of the ring network cabinet door, which increases the production cost of the ring network cabinet.
