Description
The utility model belongs to the high tension distribution system protective device, is a kind of novel high-pressure vacuum circuit-breaker.
High-pressure vacuum breaker is used for the family distribution system of rated voltage 3-10KV, and as the control and the overload of electricity, short-circuit protection is particularly useful for operating frequent occasion, as controlling furnace transformer etc.The vacuum circuit-breaker preparation of in the past using is inconvenient, and different switch cubicles adopts the high-pressure vacuum breaker of different structure, and handcart switch cabinet and fixed switch cubicle can not be with using a kind of high-pressure vacuum breaker; Volume is big, and inconvenience is installed, inconvenient operation, and cost is higher, and degree of protection is lower, and connecting-disconnecting function is stronger.
It is convenient that the purpose of this utility model provides a kind of preparation, and volume is little, and performance is good, the novel evacuated circuit breaker that cost is low.
The purpose of this utility model is achieved in that the utility model is by vacuum interrupter, insulating cover, spring, insulator, buffer, support, framework, conductive plate is formed, at framework one side fixed insulation cover, dress vacuum interrupter in the insulating cover, insulator, buffer, quiet end of vacuum interrupter and insulating cover are fixed, and draw binding post, the conductive plate of the binding post of drawing is passed in the vacuum interrupter moved end, is connected with insulator one end, and the insulator other end connects buffer by the axis of the piston, buffer is by piston, lubricating cup, cylinder body, fixed head is formed, lubricating cup is arranged in the buffer, cylinder body is arranged in the lubricating cup, and cylinder body has and goes out fuel feed hole up and down, and is oil-filled in lubricating cup and the cylinder body, be fixed with carbine on the framework top, spring one end connects carbine, and the other end connects the swing arm of main shaft, and another swing arm of main shaft connects spring, the spring other end connects lever, and the other end of lever connects the axis of the piston.
The utility model compared with prior art has following advantage:
1, preparation is convenient, can join the JYN-10 type, and the withdraw type metal enclosed handcart switch cabinet of KYN-10 type high pressure can be joined the fixed switch cubicle of GGLA-10 high pressure.
2, volume is little, and is easy for installation, and cost is low, is convenient to old scrap build.
3, degree of protection height, connecting-disconnecting function is strong.
4, under every phase vacuum interrupter movable feeler lever, increased by a cover guiding and a buffer, make the circuit breaker compact overall structure, effectively prevent the shortcoming of vacuum circuit-breaker spring, a cover labor-saving structure is adopted in circuit breaker main shaft and the transmission of arc control device moved end, guaranteed the operating pressure of arc control device, made spring force reduce half again.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a front view of the present utility model.
Fig. 2 is the A-A view of Fig. 1 of the present utility model.
Fig. 3 is a buffer structure schematic diagram of the present utility model.
Number in the figure is described as follows: 1 insulating cover, 2 vacuum interrupters, 3 springs, 4 insulators, 5 buffers, 6 hanging spring hooks, 7 supports, 8 springs, 9 frameworks, 10 binding posts, 11 conductive plates, 12 levers, 13 arc extinguishing moved ends, 14 sealing rings, 15 sealing rings, 16 pistons, 17 lubricating cups, 18 cylinder bodies, 19 fixed heads, 20 the axis of the pistons, 21 main shafts, 22 swing arms, 23 swing arms, 24 supports.
As shown in the figure, the utility model is by vacuum interrupter 2, insulating cover 1, spring 3,8, insulator 4, buffer 5, support 7, framework 9, conductive plate 11 compositions such as grade, at framework 9 one side fixed insulation covers 1, dress vacuum interrupter 13 in the insulating cover 1, insulator 4, buffer 5, the quiet end of vacuum interrupter 13 and insulating cover 1 are fixing, and draw binding post 10, the conductive plate of the binding post 10 of drawing is passed in vacuum interrupter 13 moved ends, is connected with an end of insulator 4, and the other end of insulator 4 is connected and fixed buffer 5 on the support 24 by the axis of the piston, buffer 5 is by piston 16, lubricating cup 17, cylinder body 18, fixed head 19 is formed, lubricating cup 17 is arranged in the buffer 5, cylinder body 18 is arranged in the lubricating cup 17, and cylinder body has and goes out fuel feed hole up and down, and is oil-filled in lubricating cup 17 and the cylinder body 18, be fixed with carbine 6 on framework 9 tops, spring 3 one ends connect carbine 6, and the other end connects the swing arm 22 of main shaft 21, and main shaft 21 another swing arms 23 connect spring 8, the other end of spring 8 connects lever 12, and the other end of lever 12 connects the axis of the piston 20.
During use, as when the formula short-circuit conditions occurring transshipping, vacuum interrupter opens circuit, and cuts off the electricity supply, under the effect of spring and lever, the arc control device moved end moves downward, and the axis of the piston is to pressing down, and the oil in the cylinder body is pushed down in the lubricating cup from cylinder body, oil is entered in the oil cylinder by hole on the cylinder body again in the lubricating cup, the oil medium plays the cushioning effect of action, prevents the separating brake bounce-back of vacuum circuit-breaker, has improved breaking capacity.The utility model can be directly installed on handcart switch cabinet and floatless switch cashier's office in a shop.
