Abstract
The utility model discloses a stationary-type metal closed load switch cabinet. The stationary-type metal closed load switch cabinet comprises a cabinet body, wherein a bus is arranged inside the cabinet body, the cabinet body is in metal closed box structure, and a framework of the cabinet body is formed by welding of an angle steel. A vacuum switch-disconnector, a current mutual inductor, a live display device and an operation mechanism are further arranged in the cabinet body. A coil outlet sleeve is connected with the bus, the bus is connected with the operation mechanism through the vacuum switch-disconnector, and the bus is connected with the input end of the vacuum switch-disconnector. The output end of the vacuum switch-disconnector is connected with the input end of the current mutual inductor, and the output end of the current mutual inductor is connected with the live display device. The stationary-type metal closed load switch cabinet has the advantages of being small in size, simple in structure, convenient to maintain, safe in operation and the like. Compared with the prior art, the stationary-type metal closed load switch cabinet has higher insulating level and protecting grade.
Description
Technical field
The utility model belongs to the switch cubicle technical field, relates to a kind of fixed metal enclosed loading switch cabinet specifically.
Background technology
Fixed metal enclosed loading switch cabinet closes short circuit current usefulness as cut-offfing load and short circuit and pass; On-load switch is the key equipment of distribution and ring network power supply; The a large amount of applied load switches of developed countries are as terminal protection equipment; But also there are a lot of deficiencies in the loading switch cabinet of China at present; Have potential safety hazard etc. on, complex structure big like the switch cubicle size, maintenance are inconvenient, electric, thus how can provide a kind of simple in structure, maintenance is convenient, loading switch cabinet handling safety becomes the urgent demand of people.
The utility model content
The utility model is in order to overcome the deficiency that prior art exists, provide a kind of simple in structure, maintenance is convenient, the fixed metal enclosed loading switch cabinet of handling safety.
The utility model is realized through following technical scheme: a kind of fixed metal enclosed loading switch cabinet; Comprise cabinet; In cabinet, be provided with bus; Cabinet is metal enclosed box-structure, and the skeleton of cabinet is welded by angle steel, in cabinet, also is provided with vacuum load switch, current transformer, charged display unit and operating mechanism; On bus, be connected with the outlet sleeve pipe; Bus is connected with operating mechanism through vacuum load switch; Bus links to each other with the input of vacuum load switch; The output of vacuum load switch links to each other with the input of current transformer, and the output of current transformer is connected with charged display unit through transducer.
Vacuum load switch is provided with isolation knife and ground connection cutter, and vacuum load switch, isolation knife and ground connection cutter all are arranged on the common frame.
Be provided with interlock between vacuum load switch, isolation knife and the ground connection cutter.
Charged display unit is a display, in cabinet, also is provided with the control room, and display is arranged on the panel of control room.
The beneficial effect of the utility model is: the fixed metal enclosed loading switch cabinet of this practicality has that size is less, simple in structure, maintenance is convenient and advantages such as handling safety; The utility model is compared with loading switch cabinet of the prior art; Have higher insulation level and degree of protection; The utility model can the manual spring mechanism of adapted and electric spring mechanism operate vacuum load switch, earthed switch and isolating switch adapted manual-operating mechanism.The utility model is dielectric with the air, on electric, does not have potential safety hazard, and vacuum load switch is fitted with isolation knife and ground connection cutter, and the three is contained on the frame altogether, and mutual interlocking, the operation that therefore can realize connecting bus, isolation, three stations of ground connection.
