TECHNICAL FIELD
[0001] The present application relates to the technical field of ring network switch equipment, in particular to an environmentally-friendly medium-voltage ring network switch equipment. BACKGROUND
[0002] The ring network switch equipment is a group of high-voltage switch equipment installed in a steel plate metal cabinet or made into a set of spaced ring network power supply units. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, power supply safety, and is widely used in power distribution stations and box-type substations of load centers such as urban residential areas, high-rise buildings, large public buildings, and factories.
[0003] However, the ring network switch equipment has the following defects in specific use:
[0004] 1. The internal conductive operation of the existing ring network switch equipment is mainly controlled by the structure inside the switch chamber, and the on-off operation is realized by the structure inside the switch chamber. When controlling the on-off state of the ring network switch equipment, the traditional switch chamber structure generally adopts a switch structure to control the contact or separation of the moving and static contacts to realize the on-off operation. The moving and static contacts will be in contact and collision due to the operation of the switch structure when conducting electricity, which is easy to cause electric arc phenomenon in the process of conducting connection, and further cause the problems of ablation, wear, welding and mechanical damage of the moving and static contacts, with low safety.
[0005] 2. When the internal structure of the switch chamber and other structures (fuses and grounding switches, etc.) inside the ring network switch equipment are connected for conducting electricity, the existing ring network switch equipment generally adopts the way of connector and cable connection assembly. When transmitting current, the transmitted current will be connected with the cable through the connector structure on the switch chamber structure. The transmission connector is easy to accumulate high temperature in the internal of the connector when transmitting current for a long time, with low safety. At the same time, the conductive cable inside the connector is difficult to adjust and bend according to the installation requirements during assembly, and the transmission path of the current in the connector is difficult to actively adjust and correct, which leads to high difficulty and cost during assembly and maintenance of the connector.
