Abstract
The utility model relates to a novel current switching device which includes plugs and jacks. The plug is in a cylindrical shape, and the inside of the plug is a circular elastic metal sheet. A current connecting sheet is fixed on top end faces of two plugs. The jack is in a cylindrical shape, and the inside of the jack is the circular elastic metal sheet, and lower bottoms of two jacks are fixed on an insulating plate. The novel current switching device changes an original internal and external layered turn button type current switching device into a left and right double-sleeve plug-in type structure, when the current switching operation is required, the operation can be completed only by plugging phase connecting sheets in or out corresponding jacks according to operating steps in order, so the operation is time-saving and labor-saving. The operation difficulty of the field stuff is reduced, the switching operation efficiency is improved, and the operation time and the emergency accident handling time are also shortened. The device is simple in structure. The terminal position is visual and is easy to inspect, so the operation reliability is improved. The novel current switching device can be widely used as a high voltage line microcomputer protection secondary current switching device in an electric system.
Description
Technical field
The utility model relates to a kind of electric power system high-tension line Microcomputer Protection secondary current switching device shifter.
Background technology
The circuit Microcomputer Protection secondary current switching device shifter that electric power system at present generally adopts is inside and outside hierachical structure; Adopt knob and sheet metal connected mode, since the compact conformation of device own, the less and employing knob structure in each phase gap; When switch current in flakes the time; Skin is opened the back in flakes be difficult to again hand to be reached internal layer fully and will open in flakes, need just can open by instrument sometimes, cause the Current Transformer Secondary open circuit as coming in contact bad meeting in the switch-down process; Serious threat operating personnel and device security, addressing these problems becomes urgent need.
The content of utility model
Overcome the deficiency of prior art, design the New type of current switching device shifter that a kind of operation easier is low, the misoperation probability is low, service speed fast, each terminal position is rationally directly perceived, operational reliability is high.The New type of current switching device shifter is improvements over the prior art; Two cover inserter structures about original inside and outside layering knob current switching device changed into comprise plug and jack, and plug is a cylindrical shape; Inner is that annular resilient sheet metal, electric current are fixed on top end face on two plugs in flakes; Jack is a cylindrical shape, and inside is the annular resilient sheet metal, and two jack bottom surfaces are fixed on the insulation board.Two cover inserter structures about the utility model changes original inside and outside layering knob current switching device into; When carrying out the current switching operation; Only need insert each successively or extract in the corresponding jack by operating procedure in flakes mutually and get final product complete operation, not only save time but also laborsaving; Reduce Field Force's operation easier, improve grid switching operation efficient, shorten operation and emergency episode processing time, apparatus structure is simple, and terminal position more intuitively is convenient to inspection, improves operational reliability.

Embodiment
The New type of current switching device shifter is improvements over the prior art; Two cover inserter structures about original inside and outside layering knob current switching device changed into comprise plug 2 and jack 3, and plug 2 is a cylindrical shape; Inner is that annular resilient sheet metal, electric current 1 are fixed on top end face on two plugs in flakes; Jack 3 is a cylindrical shape, and inside is the annular resilient sheet metal, and two jack bottom surfaces are fixed on the insulation board 4.Electric current 1 adopts the conductivity good metal to make in flakes.
Fig. 1, shown in Figure 2, be fixed on electric current in flakes the plug on 12 insert in the jacks 3, realize that through device 6 back wires electric current switches on and off.
Fig. 3 is device rear connection figure, this current switching device divide go up in three parts down, top line attachment Current Transformer Secondary side 5, protective device 6 inside are inserted at the middle part, by-pass current instrument transformer secondary side 7 is inserted in the bottom.
Shown in Figure 4 line running, electric current brace 1 short circuit circuit CT secondary side 7 to device 6 electric currents when circuit normally moves, insert working line electric current in the microcomputer protecting device this moment; Electric current brace 1 short circuit bypass CT secondary side 7 is to device 6 electric currents when this circuit send operation to bypass generation; Insert by-pass current in the microcomputer protecting device this moment, in handoff procedure, shown in Figure 5; Can two covers cover of one in flakes earlier be switched to bypass position by place on line; With each phase terminal of this circuit (ABCN) short circuit, overlap to the relevant position second at last again, promptly realized whole handoff procedure this moment.
