Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise Embodiment, broadly falls into the scope of protection of the invention.
Referring to Fig. 1-5, the present invention provides a kind of technical scheme: a kind of HVF vacuum circuit breaker, including base 1, base 1 The two ends of lower surface are all installed with road wheel 2, and one end of base 1 upper surface is installed with conductive component casing 3, conduction Power part casing 7, and the inside fixed installation of conductive component casing 3 it is installed with on the base 1 of component enclosure 3 side Having two ends all to run through and extend to the conductive mechanism 4 of conductive component casing 3 sidewall, the bottom of conductive mechanism 4 is fixedly connected with point Lock spring 5, tripping spring 5 is fixedly connected with one end away from one end of conductive mechanism 4 and sequentially passes through conductive component casing 3 and power Component enclosure 7 also extends to the both arms within power part casing 7 and moves connecting rod 6, and both arms move connecting rod 6 away from tripping spring 5 One end and the actuating unit 8 one end clamping being positioned within power part casing 7.
In the present invention, conductive mechanism 4 includes upper terminal 41, the side of upper terminal 41 one end by vacuum interrupter 42 with under The side of terminal 43 one end is fixing to be connected, and upper terminal 41 and lower terminal 43 fixedly mount away from one end of vacuum interrupter 42 Having Mume flower contact 44, lower terminal 43 is provided with lower carriage 45 away from the side of vacuum interrupter 42 one end, and lower terminal 43 with The junction of lower carriage 45 is provided with and is flexible coupling 46, lower carriage 45 away from lower terminal 43 one end by contact pressure spring 47 with The bottom elasticity of insulated connecting rod 48 connects, and insulated connecting rod 48 is away from one end of contact pressure spring 47 and tripping spring 5 One end is fixing to be connected.
In the present invention, vacuum interrupter 42 includes vacuum interrupter housing 421, the inside of vacuum interrupter housing 421 from It is set with download circulation flow path conducting rod 422 the most successively and uploads circulation flow path conducting rod 429, downloading circulation flow path conducting rod 422 Bottom be installed with moving contact 426, upload the top of circulation flow path conducting rod 429 and be installed with and fit with moving contact 426 phase The static contact 425 joined, and the junction uploading circulation flow path conducting rod 429 bottom and vacuum interrupter housing 421 is provided with end Lid flange 423, vacuum interrupter housing 421 inwall of end cap flange 423 side is provided with ceramic insulation shell 424, downloads circulation Road conducting rod 422 bottom is provided with guide bearing 428 with the junction of vacuum interrupter housing 421, guide bearing 428 side It is movably installed with in vacuum interrupter housing 421 and is sleeved on the corrugated tube 427 downloaded outside circulation flow path conducting rod 422.
In the present invention, the outer surface of moving contact 426 and static contact 425 all offers in screw-shaped magnetic conductive groove 4261.
In the present invention, actuating unit 8 includes main shaft 81, and main shaft 81 overlaps intrinsic cam 82, dropout machine the most successively Structure 83 and disc spring 84, the outward flange of cam 82 and both arms move the opening clamping of connecting rod 6, and driving chain is passed through in the side of disc spring 84 85 are in transmission connection with the driving gear 86 being positioned in rotating shaft 88, and overlap intrinsic ratchet in the rotating shaft 88 of driving gear 86 side 87。
In the present invention, vacuum interrupter 42 is firmly installed on insulating support and bearing, therefore can bear switch motion Produced stamping press, contact compression spring can compensate arc erosion automatically, but this ablation amount is the trickleest.At moving contact 426 The moment disconnected with static contact 425, electric current, by the certain point focused on contact or a certain several point, causes the violent increasing of resistance Add the rapid rising with temperature, produce metallic vapour between contact, concurrently form high electric field, cause field emission and gap to hit Wearing, then form vacuum arc, electric arc is always maintained at zero point transition next time, extinguishes when current zero-crossing point, the gold of conduction Belonging to steam to be condensate on metallic shield in several milliseconds, the dielectric strength between contact is recovered rapidly.
Contact is random for opening moment Opposed Current phase angle, from contact be opened between current zero-crossing point any Moment cut-offs, and between contact, dielectric strength can be recovered rapidly, and the longest arc time is less than 15 milliseconds.Vacuum arc Needing to excite metallic vapour to safeguard, during for preventing from cut-offfing inductive circuit, it is super that vacuum arc extinguishes generation before shunting zero crossing High voltage, according to different breaking currents and arc-chutes type, separately designs geometries and the size of contact, it is ensured that value of damming Can drop to the least.
Longitudinal magnetic field can prevent electric arc from gathering, and is also such when timely electric current is the biggest, therefore, and answering in dish type contact surface Power can be uniformly distributed, and prevents to puncture again.Under normal circumstances, it is necessary to take the electric arc of various conventional arc-suppressing method to carry out cold But, even if also should be such when the most minimum arc extinguishing distance of contact and striking energy, but, owing to metallic vapour has extremely strong Conductive properties, and the arc voltage value produced is only between 20V to 200V, therefore, the electric arc ignited in vacuum circuit breaker Need not cooling, due to above reason and shorter arc time, the arc energy produced in chopper is the most small, and this is also It it is this vacuum circuit breaker reason with the very long life.
The present invention is provided by the vacuum interrupter 42 sealed, it is ensured that moving contact 426 and static contact 425 will not be because of Switching manipulation and be significantly affected, as long as applying suitable contact pressure, this resistance just can keep invariable, except this it Outward, contact also will not be oxidized, will not make moist and contamination, and therefore, contact metal can keep cleaning, contact gap opening part Dielectric strength can remain kilter;Conductive mechanism 4 and actuating unit 8 simple in construction, movable part is few, and weight is relatively Gently, operationally noise and vibration are less, and its operating mechanism is safeguarded more convenient, has the longest expected service life, its behaviour Make number of times up to 30000 times, owing to the erosion amount of moving contact 426 and static contact 425 is the least, therefore, the contact under rated current Life-span is up to 20000 times;Normal wear and aging parts, with little need for maintenance, only need to be carried out by this HVF vacuum circuit breaker Safeguard, so that it may guarantee that operation is the most reliable, vacuum interrupter 42 and bearing thereof be need not safeguard, simultaneously for directly occurring Fault after transformator, electromotor or current limliting choke coil may cause full load short circuit current, and fault occurs at choke coil Time afterwards, the rate of pressure rise of transient recovery voltage may be up to 10kV more than μ s, uses this vacuum circuit breaker can be very easily Dissolving this type of precarious position, the superior low vibration compact with its mechanism, lightweight and quiet that is in of the present invention runs, Yi Jiqi Reliability dough-making powder is maintained, high safety.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, permissible Understand and these embodiments can be carried out multiple change without departing from the principles and spirit of the present invention, revise, replace And modification, the scope of the present invention be defined by the appended.
