The opening-closing operating mechanism includes a casing body, a link mechanism and a permanent magnet mechanism; and the link mechanism includes a long shaft and a short shaft. Particularly, a manual opening transmission shaft and a manual closing transmission shaft are installed on the casing body; the two shafts are respectively provided with an opening handle and a closing handle; a short shaft tail end is installed on the manual opening transmission shaft; an opening crank arm of the short shaft tail end is placed into the link mechanism; an opening spring is installed at the tail portion of the short shaft; the manual closing transmission shaft is in drive connection with a spring control mechanism; a transmission pin arranged on the spring control mechanism is connected with the long shaft of the link mechanism; and an elongated slot is arranged at the connecting position of the long shaft and the transmission pin. The permanent magnet vacuum circuit breaker solves the problem that an existing permanent magnet vacuum circuit breaker can not work under the condition of power failure, and is particularly suitable for being used by a power transmission system with 50Hz three-phase alternating current and 12kV rated voltage.

(2) background technology: at present, the switch that uses in the electric power system both at home and abroad is various in style, permanent magnetic actuator vacuum circuit breaker is shown one's talent as a kind of circuit breaker of novel operating mechanism, it is little to have volume, in light weight, the precision height, reaction speed is fast, high reliability, life-span is long, characteristics such as non-maintaining, but as a kind of mechanism by power initiation, still there are some fatal weakness in it, under the situation of non-transformer or power supply deficiency or power failure, permanent magnet mechanism can't start, cause normally divide-shut brake of circuit breaker, might in electric power system, cause a serious accident afterwards.Therefore, must set up a kind of manual divide-shut brake device, can under non-transformer or debugging mode, split to close for the user and carry out divide-shut brake, and can not impact the electronic divide-shut brake of permanent magnet mechanism.
(3) summary of the invention: the purpose of this utility model is exactly will solve under the situation of existing permanent magnetism vacuum circuit-breaker non-transformer or power failure, and the problem that can't work provides a kind of permanent magnetism vacuum circuit-breaker with manual on/off switch device.
Concrete scheme of the present utility model is: improve at existing permanent magnetism vacuum circuit-breaker, it is mainly by the three-phase pole, current transformer and divide-shut brake operating mechanism three are partly formed, described divide-shut brake operating mechanism includes housing, be contained in the housing and the linkage that is connected with the pull bar of three-phase pole, and the permanent magnet mechanism of drive link mechanism, include major and minor axis in the described linkage, diaxon is connected with moving iron core two ends in the permanent magnet mechanism respectively, it is characterized in that: manual brake separating power transmission shaft and closing by hand power transmission shaft are installed on housing, and diaxon is equipped with separating brake handle and switch lever respectively; The minor axis tail end that the separating brake connecting lever places linkage is installed on the described manual brake separating power transmission shaft, and tripping spring is housed at the minor axis afterbody; Described closing by hand power transmission shaft drives and connects a spring operation, and this spring operation is provided with trundle and is connected with major axis in the linkage, and has elongated slot with the trundle junction on major axis.
For making more reasonable structure, it is more reliable to work, and baffle ring is housed in the inner of described tripping spring in the utility model fixedly fixedlys connected with minor axis, and the outer end of tripping spring is equipped with the slip baffle ring and is connected with the contact of separating brake connecting lever.
The utility model is positioned over closing by hand device and manual switching-off device respectively the both sides, front and back of permanent magnet mechanism, and idle stroke long slot bore of the design of the major axis in linkage, minor axis is designed to the part of manual switching-off device, the closing by hand device links to each other with major axis by trundle, and minor axis and sluice separating spring, separating brake connecting lever constitute manual switching-off device.When the needs closing by hand, spur the energy storage switch lever back and forth, after energy storage was held completely, the closing by hand device was given major axis by trundle with the energy delivery that spring discharges, and finishes making process afterwards, when the needs manual brake separating, as long as pulling manual brake separating handle drives the separating brake connecting lever and compresses the tripping spring energy storage to the right, when handle is moved certain angle to downwards, sluice separating spring releases energy, and finishes the separating brake process afterwards.The utlity model has following characteristics:
1. can under situations such as non-transformer or power shortage, power failure, realize divide-shut brake, guarantee the normal operation of electric power system by manual operation.
2. closing by hand and switching-off device place the both sides, front and back of permanent magnet mechanism respectively, rationally utilize the space of circuit breaker.
3. the idle stroke of major axis design has guaranteed that electric operating and manual operation can not make a difference mutually.
4. minor axis, sluice separating spring, separating brake connecting lever are formed manual switching-off device jointly, can rationally accurately carry out transmission.
5. closing by hand device independently is connected with the major axis of permanent magnet mechanism, after the switching-in spring energy storage is full, can release energy automatically, finishes the closing by hand process.
