Description

Protection device for be used for looped netowrk cabinet Technical Field The utility model relates to the technical field of ring main units, in particular to a protection device for a ring main unit. Background With the rapid development of cities, the land resources available for building substations and distribution facilities are increasingly limited. The ring main unit is gradually miniaturized, the miniaturized ring main unit can reduce manufacturing cost, cost in transportation and installation processes, occupied area and land purchase or lease cost on the premise of guaranteeing power transmission efficiency and service quality, precious urban space can be effectively utilized through flexible arrangement, and urban power grid planning and layout flexibility is improved. However, the existing many miniaturized ring main units are generally short in height, so that the outgoing line positions of connecting cables in the ring main units are low, and when the ring main units are installed, the joint parts of high-voltage cables easily extend to the outgoing line holes and even exceed the ring main units, so that great potential safety hazards exist.
