Abstract
The utility model relates to a vacuum circuit breaker switchgear for a 35KV single break. A switchgear cabinet 29 is adopted to match with the circuit breaker switchgear. The upper side of the switchgear 1 is provided with a vacuum circuit breaker, a spring operating mechanism 5, and an interlock system 4. The lower part of the switchgear 1 is provided with a roller 10 which is matched with the switchgear cabinet. The interlock system 4 can be interlocked with the switchgear cabinet. A movable guide rod which is arranged at the lower end of the explosion chamber of the vacuum circuit breaker is connected with a lower wire outlet seat through the roller and a conductive rod. The utility model has the advantages that the maintenance is convenient, the breaking performance corresponds with the technical requirement, and the utility model can be interchanged with a switch cabinet switchgear with the same voltage level in the existing power system.
Description
The utility model relates to a kind of 35KV single break vacuum circuit-breaker handcart.
The domestic 35KV of yet there are no single break, large-capacity vacuum circuit breaker are contained in the report on the handcart at present, when circuit breaker breaks down or need repairing, need to change switch cubicle and other equipment, maintenance time is long, and electrically conducting manner is to adopt the mode that is flexible coupling between the moving guide rod of traditional circuit breaker lower end and following outlet, when big voltage circuit breakers cut-offs, is not easy to reach rate request, mounting or dismounting are because of spatial limitation, and are relatively more difficult.
The utility model just provides a kind of maintenance of being convenient to, and break performance meets the 35KV single break vacuum circuit-breaker handcart of specification requirement.
Solution of the present utility model is such: the mode that adopts handcart cabinet and circuit breaker cart adapted, vacuum circuit-breaker, spring-operated and interlock system are installed on dolly, the bottom of handcart is equipped with the roller that matches with the handcart cabinet, interlock system can be interlocked with the handcart cabinet, when circuit breaker breaks down or when needing repairing, can pull out handcart immediately, standby handcart is pushed, can recover immediately to send.In addition, adopt roller and conduction guide post connected mode between moving guide rod in vacuum circuit-breaker arc control device lower end and the following outlet seat, when circuit breaker was cut-off, the speed of cut-offfing met the requirements.
The utility model has the advantages that the maintenance of being convenient to simple in structure, break performance well can with existing electric power system in exchange with the switch cabinet handcart of electric pressure.
Accompanying drawing is embodiment of the present utility model:
Accompanying drawing 1 is the handcart structure principle chart.
Accompanying drawing 2 is drive system schematic diagrames.
Accompanying drawing 3 is handcart and handcart cabinet connection diagram.
The utility model is to adopt handcart cabinet 29 and circuit breaker cart 1 adapted, on the handcart 1 vacuum circuit-breaker is installed, spring operating mechanism 5 and interlock system 4, the bottom of handcart 1 is equipped with the roller 10 that matches with handcart cabinet 29, interlock system 4 can be interlocked with handcart cabinet 29, between the guide rod 21 of vacuum circuit-breaker arc control device lower end and following outlet seat 16, adopt roller 22 and conducting rod 23 connected modes, in the present embodiment, the moving guide rod 21 of vacuum interrupter is by 6 pairs of rollers, 22 conductions, both guarantee the good contact in deciliter process, and played auxiliary guide effect for again the motion of moving guide rod 21.Having on handcart 1 can be around the no-load voltage ratio bar 26 of fixed axis rotation and connecting joint 4 and touch spring 27, the axis of the axis of connector 4 and touch spring 27 staggers mutually, form biased form, can guarantee the pressure that dynamic/static contact is bigger, can make the spring size unlikely excessive again, on the other hand, because the output angle of CT10 spring operating mechanism 5 is bigger.And the stroke of vacuum interrupter 19 is less, adopts bias structure can form good size in the centre and cooperates.The closing position of connecting lever 28 is designed to after contact closes a floodgate, and 27 one-tenth vertical configurations of connecting lever 28 on the pedestal 14 and touch spring form self-locking.Can guarantee well to close a floodgate stability.
The switch cubicle of present embodiment belongs to the cabinet-type structure, it is made up of with handcart 1 two parts the cabinet 29 that shaped steel and steel plate are bent into, handcart 1 roller 10 and handcart cabinet track 32 adapt and can relative slippages, face down bonding has the location-plate 31 that advances, pulls out and interlock for handcart 1 in orbit, also play interlocked usefulness simultaneously, prevent charged mobile handcart, when handcart 1 is shifted onto, dynamic/static contact 30 well inserts, and guarantees reliability service.
On the handcart 1 of present embodiment panel 2 is installed, spring operating mechanism 5, vertical pull bar 6, big rotating shaft 7, level insulation pull bar 13, connecting lever 8, band touch spring 27, no-load voltage ratio bar 26 closes a floodgate by the moving guide rod 21 that connector 24 drives vacuum interrupter 19, fairlead 25 is equipped with in connector 24 outsides, the big rotating shaft of vacuum circuit-breaker 7 both sides are equipped with separating brake oil buffering 8 respectively, close a floodgate and cushion 9, vacuum interrupter 19 is contained in outlet seat 20 respectively, following outlet seat 16, above the pedestal 14, there are four insulating bars 18 to gain in strength all around, use big insulator 3 respectively with pedestal 14 and go up outlet seat 20, pony insulator 11, column insulator 12 is fixed on the handcart 1.
In the accompanying drawing, the 17th, contact, the 15th, electroconductive aluminium strip
