Description
Technical field
The utility model belongs to Distribution Automation Technology field, particularly relates to handing over from short circuit of a kind of distribution terminal connector and adopts terminal.
Background technology
Develop rapidly in process at distribution automation, the stability of distribution terminal, practicality, control security and communication security require more and more higher, but the stable and safety of terminal, also more and more higher to the safety requirements of whole circuit, while following basic laws of circuit, more will respect the prime design requirement of electricity, current circuit cannot be opened a way, and voltage circuit cannot short circuit.Operating current transformer, because its load impedance is very little, runs on short-circuit condition substantially, the mutual degaussing of magnetic flux that the magnetic flux produced due to secondary current and primary current produce, and the magnetic flux density in iron core can maintain lower level.Now, the secondary voltage of current transformer is also very low.When run in second open circuit time, the electric current of primary side is constant, and secondary current equals zero, then secondary current produce degaussing magnetic flux disappear.Like this, primary current all becomes exciting current, and the iron core of current transformer is seriously saturated, its secondary produces very high voltage, produces danger, because the suddenly saturated core loss that makes of iron core increases to equipment and personnel, iron core generates heat, insulation likely burns out, and causes a series of consequence, causes terminal called cisco unity malfunction, communication can be stopped time serious, cause the monitoring of primary side circuit to lose efficacy, can impact residential electricity consumption, serious consequence occurs.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of friendship from short circuit and adopts terminal, and this design can realize automatic short-circuit and remove the function of short circuit, ensure that equipment control security, solves the problem of existing equipment communication instability.
The technical scheme in the invention for solving the technical problem is: a kind of friendship from short circuit adopts terminal, comprises terminal board and terminal base, and the screw of the screw that terminal board and terminal base are arranged by fixed terminal and stiff end stroma realizes riveted joint and plugs together; Friendship is adopted terminal and is also comprised the screw of fixed terminal row and the screw of stiff end stroma; Terminal base comprises insulated mounting plate, and insulating mounting front edge of board has boss, and terminal board comprises short board and plug connector, and terminal base comprises socket connector; Spring leaf is arranged in terminal board, and mat is arranged in terminal base; When terminal board and terminal base riveted joint plug together, the screw that stiff end stroma aimed at by fixed terminal row screw inserts realization guiding; In the process of terminal board insertion end stroma, insulating mounting front edge of board boss in terminal base promotes the short board in terminal board, spring leaf compresses, make short board away from the head of the plug connector in terminal board, and move to the position of insulating case, the plug connector separating contacting state of short board and terminal board, thus each plug connector relieved in terminal board is to the mutual short-circuit condition between terminal board, now, socket connector in terminal base produces with the plug connector in terminal board and contacts, and makes to adopt terminal from short circuit friendship and reaches normal work; Realize namely pulling out and namely breaking, plug and play, this structure conveniently can be embedded in distribution network terminal equipment and works; When terminal board and terminal base are separated from each other, in terminal board, each connector automatically and shell conducting, is namely in from short-circuit condition; Contact pin is divided into long contact pin and short contact pin, and long contact pin and short contact pin are welded in mat respectively; When terminal board and terminal base plug together, first remove short-circuit function, then realize contact and normally plug together; Long contact pin stretches out outside working of plastics, and short contact pin does not stretch out outside working of plastics.
The beneficial effects of the utility model: a kind of friendship from short circuit adopts terminal, automatic short-circuit can be realized due to this design and remove the function of short circuit, solve the impact of malfunction on equipment, can be widely used in high anti-interference equipment control system, be particularly suitable for the occasion that equipment malfunction makes to produce serious consequence; Device security performance is improved, when reply site environment changes situation greatly, this design makes distribution automation be achieved in the operating environment that the whole nation is more severe on a large scale, to the network system in future, fail safe, the realization of intelligent network distribution has important function.
