Abstract
The key factor of the contact subassembly ability of cut -offfing includes: contact diameter, contact dish material, structure of contact terminal etc. At present, the used contact subassembly of vacuum interrupter can not satisfy and promotes the explosion chamber and cut -off the performance and accomplish that its is miniaturized, simultaneously since in the contact subassembly processing design of contact cup unreasonable, cause contact cup and contact tray or contact dish when the sealing -in becomes the part, there is the solder overlap joint in the otch of contact cup, has reduced the ability of cut -offfing of contact subassembly, needs secondary treatment usually, as if not handling the risk that then has the contact and lose the ability of cut -offfing, there is quality hidden danger in the cost -push. The utility model discloses a through providing a novel vacuum interrupter contact subassembly, under the condition that does not change contact subassembly fluting quantity, fluting angle, contact subassembly volume, locate most advanced processing through the crossnotching, promote vacuum interrupter's the ability of cut -offfing, improve vacuum interrupter's reliability.
Description
Technical field
The utility model is related to transmission ＆ distribution electro-technical field, is related to the contact assembly of electron tube, more particularly to a kind of
Novel vacuum interrupter contact assembly.
Background technology
Vacuum circuit breaker relies on its stable performance and the big advantage of safety and environmental protection two to be used widely in power system, very
Empty arc-chutes contact assembly is the core component of vacuum circuit breaker, its effect be when drop-out current vacuum interrupter fracture it
Between produce necessary magnetic field.With the sustainable development of power industry, the requirement that performer is cut-off in power system to it increasingly increases
Height, vacuum circuit breaker has become inexorable trend to Large Copacity, miniaturization development.The reduction of contact assembly size can make vacuum go out
The size of arc chamber external diameter and caliber is reduced, thus reducing the size of overall vacuum breaker, reaches the purpose of miniaturization.
The key factor of contact assembly connecting-disconnecting function includes：Contact diameter, contact disk material, structure of contact terminal etc..At present, very
Contact assembly used by empty arc-chutes can not meet lifting arc-chutes break performance and complete its miniaturization, simultaneously because touching
In head assembly, the fabrication design of contact cup is unreasonable, causes contact cup with contact pallet or contact disk when sealing-in becomes part, touches
There is solder overlap joint in the otch of head cup, reduce the connecting-disconnecting function of contact assembly, it usually needs after-treatment, and cost increases,
If not carrying out processing, there is the risk that contact loses connecting-disconnecting function, there is hidden danger of quality.
Utility model content
For solving the above problems, the purpose of this utility model is by providing a kind of Novel vacuum interrupter contact assembly,
Do not change contact assembly fluting quantity, included angle, in the case of contact assembly volume, by most advanced and sophisticated place at cross-notching
Reason, the connecting-disconnecting function of lifting vacuum interrupter, improves the reliability of vacuum interrupter.
For reaching above-mentioned purpose, the utility model provides technical scheme below：
A kind of Novel vacuum interrupter contact assembly, including contact cup 1, support base 2, contact pallet 3 and contact disk 4, institute
State contact cup 1 and there is fluting 5, the corner α of described fluting bottom starting point to tool wedge angle slotted top 6 is more than fluting bottom starting point and arrives
The corner β of no wedge angle slotted top 7.
Further, the corner α of described fluting bottom starting point to tool wedge angle slotted top is 118 ° ~ 120 °, described fluting
The corner β of bottom starting point to no wedge angle slotted top is 112 ° ~ 115 °.
Further, the corner α of described fluting bottom starting point to tool wedge angle slotted top is 120 °, and described fluting bottom is risen
The corner β of point to no wedge angle slotted top is 115 °.
Described contact pallet 3 is encapsulated by welding with contact cup 1, contact disk 4.
Compared with existing contact assembly, the quantity of contact cup fluting of the utility model contact assembly, angle, overall height
Degree, thickness, internal-and external diameter are all unchanged, only increase the wedge angle removing tool wedge angle slotted top 6, form no wedge angle slotted top
7.
Wedge angle due to the tool wedge angle slotted top of existing contact cup has guide effect, easily in contact assembly sealing-in
Cheng Zhong, solder is internal to fluting along corners bit stream after softening.The utility model contact cup passes through to remove tool wedge angle fluting top
The wedge angle at end is processed, and reduces stacked solder when contact cup is connect with contact pallet or contact disk seal, it is to avoid solder overlap joint contact cup is opened
Groove, thus reaching improving product connecting-disconnecting function, minimizing is secondary to do over again, reduces cost.
