Automatic energy storage type combined electric appliance

Abstract

The invention relates to an automatic energy storage type combined electric appliance which comprises a spring operating mechanism and a fusing mechanism. The fusing mechanism is located at the lower end of the spring operating mechanism, the spring operating mechanism comprises an opening energy storage spring and an opening half shaft used for locking the opening energy storage spring, and the automatic energy storage type combined electric appliance further comprises a fusing opening transmission assembly. The fusing opening transmission assembly is installed in the fusing mechanism, and the upper end of the fusing opening transmission assembly extends into the spring operation mechanism. The opening half shaft is connected with an opening tripping plate. When the fusing mechanism is fused, the fusing opening transmission assembly jacks up and pushes the opening tripping plate to rotate, and when the opening tripping plate rotates, the opening half shaft is driven to rotate, so that the opening action can be automatically started when the fuse is fused and tripped, timely opening is ensured, and the safety is ensured.

Description

technical field [0001] The invention relates to the field of ring network cabinets, in particular to an automatic energy storage type combined electrical appliance. Background technique [0002] The ring network cabinet is a group of transmission and distribution electrical equipment (high-voltage switchgear), which is installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. Its core part uses load switches and fuses. The utility model has the advantages of simple structure, small size, low price, can improve power supply parameters and performance, and power supply security. It is widely used in distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises. [0003] The existing ring main unit is generally equipped with a spring operating mechanism, which can control the opening and closing of the load swi...

AI Technical Summary

Problems solved by technology

The comparative document CN20672697 discloses a "spring operating mechanism and ring network cabinet" to solve the technical problem of the short service life of the spring operating mechanism in the prior art. In its technical solution, the closing spring and the opening spring are used Carry out energy storage separately, and use the spring potential energy stored in the closing spring and the opening spring to drive the closing or opening action of the load switch; wherein, after closing, the opening spring is in a stretched energy storage state, and the opening The brake spring is connected with the output unit and the opening holding detent unit, and the opening semi-shaft that can be used to lock the opening holding detent unit is set. Keep the detent unit unlocked, at this time the output unit will rotate under the elastic force of the opening spring and enter the opening state

[0004] However, when the opening operation is required, the technical solution disclosed in the comparative document CN20672697 can only allow one opening operation, that is, by using the opening electromagnet to push the opening trip plate connected to the opening half shaft, the opening The brake half shaft rotates to realize the opening operation

Therefore, the spring operating mechanism of the reference document can only allow the opening operation to be realized by energizing the opening electromagnet, and cannot perform the opening operation by other means
