Abstract
The invention relates to an enclosed ring network switchgear, which comprises a cabinet body. An instrument room and a bus room are formed on the upper part of the cabinet body. Load switches are arranged on the lower part of the bus room. Current transformers and insulators are arranged on the lower parts of the load switches. A protective conductor is arranged on one side of the bottom of the cabinet body. The enclosed ring network switchgear is simple in structure and convenient to daily maintain, and can reliably run.
Description
Technical field
The present invention relates to a kind of power supplying and distributing equipment that is applied to electric power system, be specifically related to a kind of looped network switch apparatus.
Background technology
Ring main unit has played the function of branch, segmentation and contact in distribution system, therefore in the cable net transformation of ground, city, be used widely.Ring main unit is a kind of miniaturization, switchgear cheaply, is applicable to the power supply of ring network power supply and terminal, and the distribution system like city ring network power supply, industrial and mining enterprises, skyscraper, residential quarters etc. also is applicable to the integral and intelligent transformer station of packing into.At present, in the production industry of ring main unit, the looped network cabinet all is that steel plate is welded mostly; There are shortcomings such as yielding, that precision is low, cost of manufacture is high, manufacturing intensity is big; And former ring main unit interior layout is unreasonable, is easy to generate fault, has brought a lot of inconvenience for people's life.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of simple in structure, reliable in order to overcome deficiency of the prior art, the convenient sealing of regular maintenance looped network switch apparatus.
Technical scheme: in order to solve the problems of the technologies described above; A kind of sealing looped network switch apparatus of the present invention; It comprises cabinet, is provided with control room and bus-bar room on said cabinet top, is provided with on-load switch in said bus-bar room bottom; Be provided with current transformer and insulator in said on-load switch bottom, be provided with the protection conductor in said bottom of cabinet bulk one side.
Be provided with inspection hole at said cabinet middle part.
One side is provided with operating mechanism and interlocking device in the bottom of said inspection hole.
Be provided with illuminating lamp in said cabinet bottom.
The present invention is a case structure; Cabinet bends part by special-purpose section and priming sheet and assembles; It can manual operation or operation automatically; The mechanical interlocks that has flexibility and reliability between on-load switch and earthed switch and the cabinet door meets " five is anti-" requirement, guarantees personal safety and operation, maintenance, maintenance safety.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: internal structure arrangement of the present invention is reasonable, reliable, and regular maintenance is simple, and integrated operation is simple.
