Abstract
The invention relates to an embedded pole part and method of manufacture the same, with vacuum interrupter which is embedded or assembled in an expoxy resin or thermoplastic housing, with a fixed contact and a movable contact, wherein the fixed contact is electrically and mechanically fixed to an upper electrical terminal, according to the preamble of claim 1 and 8. In order to damp and/or reduce this bouncing at the upper terminal or at the terminal concerning to the fixed contact of the pole part, the upper terminal or the terminal according to the fixed contact is covered by a damping layer between the terminal surface and the embedding or surrounding housing.
Description
Technical field
The present invention relates to according to the method for the embedded pole part as described in the preamble of claim 1 and 8 and the described embedded pole part of manufacture, described embedded pole part has vacuum interrupter, described vacuum interrupter embeds or is assembled in epoxy resin or thermoplasticity housing, described vacuum interrupter has fixed contact and movable contact, wherein, fixed contact is electric and be all fixed to electric terminal aspect mechanical two.
Background technology
Substantially, it is inner that vacuum interrupter is embedded in utmost point enclosure interior and epoxy resin or thermoplastic.By hot-moulded or injection technique, can realize this object.Alternatively, vacuum interrupter is also introduced in ready premade shells, and then it is known as assembly type utmost point parts.The vacuum interrupter rigidity that is arranged in embedding enclosure interior is embedded in housing.
During contact making operation, fixed contact almost can not move, the following pulse-on of contact blade:
P＝m×V
It produces high active force and mechanical impact, and duration dP/dt is less, and reason is that fixed contact rigidity is embedded in housing.This causes conventionally for upper contact head, producing so-called bounce-back, and described upper contact head is generally fixed contact.Then will towards the closing motion of upper contact head, cause producing shock because of lower contact.
In addition be known that between arc control device surface and epoxy resin housing by damping layer covering vacuum arc control device.
Yet, the lip-deep damping layer of arc control device can not damping for the bounce-back on the upper terminal of fixed contact.
Summary of the invention
Therefore, the object of the invention is damping and/or reduce this bounce-back at upper terminal or the terminal place corresponding with the fixed contact of utmost point parts.
Utilize the present invention to address this problem, that is, upper terminal or the terminal corresponding with fixed contact are covered by the damping layer between terminal surfaces and embedding housing or periphery housing.Therefore, this damping layer is close between terminal surfaces and housing, and the damping when connecting can be prevented or damping bounce-back the most effectively.Damping layer is made by elastomeric material and/or at least compressible or at least part of compressible material.
Therefore, some advantageous materials are below being proposed.
The first is polyurethane for the damping layer material of terminal.This material is solid and have high mechanical resistance and thermal endurance, and can in the situation of subsequent thermal resin or thermoplastic process, accept processing by keeping its mechanical features.
The another kind of material that is used for the damping layer of terminal is silicone.This material is solid and have high mechanical resistance and thermal endurance, and can in the situation of subsequent thermal resin or thermoplastic process, accept processing by keeping its mechanical features.
But, can use various elastomers.
Other replacement scheme of the damping layer material of terminal is rubber.
Other replacement scheme of the damping layer material of terminal is polysiloxanes.
In addition advantageously, the damping layer material of terminal is the mixture of polyurethane and/or rubber and/or polysiloxanes, and/or has the layered composite of at least two kinds in above-mentioned material or combination of materials.
This means that damping layer material self can be material blends or self be layered composite structure.At material layer, have bubble structure and/or the internal particle as steeped in hollow glass and/or provide in the situation of inside grit of nonlinear characteristic, damping can regulate.
Favourable embodiment is that damping layer directly extends contiguously with the inner surface of housing in upper area, and closely extends with lid or the crown cap of the vacuum interrupter of adjacent positioned in the region towards vacuum interrupter.This means damping layer directly to contact with vacuum interrupter at a side place and directly contact with this terminal inner walls around at opposite side place.
According to described method, basic conception of the present invention is: additionally, before covering in the assembly group of design in advance will be introduced in described housing by hot epoxy or thermoplastic process or by described housing, upper terminal or the terminal corresponding with described fixed contact will be covered by elastomer damping layer and/or at least part of compressible damping layer.
Therefore, result is that this positioning action that is arranged in the additional special damping layer at fixed contact terminal place can be attached to the manufacturing process of utmost point parts easily, and obtains the final high performance utmost point parts that bounce-back reduces.
Accompanying drawing explanation
Fig. 1 shows the cross section of utmost point parts.Alternatively, vacuum interrupter can be incorporated in housing alternatively, and has damping layer between vacuum extinction chamber surface and housing madial wall.
Embodiment
The fixed contact of vacuum interrupter is arranged in upper area.Upper contact head is with upper terminal mechanical connection and be electrically connected to.Upper terminal is at least covered by the above-mentioned damping layer between terminal surfaces and housing on the surf zone of housing inner side at it.In the situation of contact making operation, unshowned lower contact by rapid movement and when contact is connected by the bounce-back causing with respect to upper fixed contact.Then by this additional damping layer on terminal, effectively reduce this bounce-back.Therefore, this terminal is surrounded by this damping layer completely in the surface that is positioned at enclosure interior.In addition, with this damping layer material, fill the space between the lid of vacuum interrupter of this upper terminal and next-door neighbour location, make not exist the vibration wave energy being caused by bounce-back not weaken and be transmitted to this terminal.
As shown in the figure, exist by damping material is incorporated on fixed contact, so that damping material omits micromotion, reduce the possibility of the rigidity of fixed contact side.Damping material can be polyurethane or silicone.Must apply by this way damping material, the layer that for example makes it possible to be positioned on the top of vacuum extinction chamber cap and on upper contact head terminal by use is realized a little motion.This application can also be applied on localized area, on these localized areas, can realize motion equally.This power that causes the pulse because of application equation dl/dt to produce reduces, and the duration that caused in addition rebounding between two contacts shortens.Vacuum interrupter can be embedded in epoxy material in the situation that having layer of compensation or not having layer of compensation.Insulating material for utmost point parts can be epoxy resin, thermoplastic, BMC or other insulating material.
Effect is the bounce-back duration that has reduced utmost point parts places.
