Description
Technical field
The invention belongs to high-voltage switch apparatus field, be specifically related to a kind of contact for 12kV switchgear assembly
Box.
Background technology
In middle pressure switchgear assembly, the use of contact box is the most universal, contact box act primarily as be dielectrically separated from and
Couple the effect of transition.
At present, the cell material of contact box is thermosetting epoxy resin material, uses automatic pressure gel (APG) technique
Molding.This kind of technique material requested is many, finished product weight, and production efficiency is low, and product is the most damaged；After thermosetting epoxy resin material admittedly
Change time length and energy resource consumption are big, and production scene is easily filthy and is difficult to clean up, and waste product material can not recycle, and
Being difficult under field conditions (factors) degrade, natural environment causes the biggest pollution, traditional handicraft can not meet environmental friendliness, green
The requirement of environmental protection.
Environment-friendly thermoplastic material is utilized to replace thermosetting epoxy resin material to become one of study hotspot.
CN104861644A discloses a kind of glass fibre reinforced nylon thermoplastic, its have excellent mechanical property, thermostability,
Splitting resistance and the electrical insulating property of excellence；Compared with thermosetting epoxy resin system, product lightweight, dielectric strength increases
By force, mechanical strength improves 3-4 times, is fully able to meet the properties requirement of 12kV switchgear assembly.
CN201774144U discloses a kind of switchgear dedicated contact box, connects including barrel type insulation body with by transition shoulder
Being connected on the sealing insulator of barrel type insulation body one end, be provided with static contact and install inserts in sealing insulator, static contact installs inserts
For cylinder.Existing contact box, in sealing insulator, the thickness that static contact installs inserts top end is thin, at side periphery
Thickness is thick, and when using thermoplastic injection mo(u)lding, sealing insulator can cause contractility uneven because of became uneven, enters
And cause product to ftracture.
Summary of the invention
It is an object of the invention to provide a kind of contact box, thus solve in prior art, the sealing insulator of contact box is thick
Thin inequality, easily causes the problem that product ftractures.Present invention simultaneously provides a kind of switchgear using above-mentioned contact box.
In order to realize object above, the contact box of the present invention be the technical scheme is that
A kind of contact box, including barrel type insulation body and the sealing insulation that is connected to barrel type insulation body one end by transition shoulder
Body, is provided with static contact in sealing insulator and installs inserts, and described static contact is installed the outer rim of inserts and extended at transition shoulder.
The contact box that the present invention provides, installs inserts and coordinating of sealing insulator by static contact, makes sealing insulator
The thickness of various piece is of substantially equal, it is to avoid the product cracking caused because of became uneven.
Further, described static contact installation inserts deviates from the surface of barrel type insulation body side is spherical structure.
It is spherical structure that described sealing insulator deviates from the surface of barrel type insulation body side, the spherical structure of sealing insulator
The spherical structure installing inserts with static contact is arranged concentrically, or the spherical structure of sealing insulator installs inserts with static contact
The centre of sphere line of spherical structure and the dead in line of barrel type insulation body.Described transition shoulder has the step transition of annular setting
Section.The setting of step transition section can prevent stress cracking, simultaneously good looking appearance further.
It is the umbrella handle mushroom construction towards barrel type insulation body that described static contact installs inserts.
The static contact installation inserts of mushroom-shaped, while realization sealing insulator thickness everywhere is of substantially equal, also can enter
One step eliminates static contact in forming process and installs the internal stress near inserts, further increases product quality.
It is casting aluminium material that described static contact installs inserts.It has easily processed into type, the feature of low cost.
The outer wall of described barrel type insulation body is provided with external shed, and inwall is provided with interior full skirt.By external shed, interior full skirt
Design can be effectively increased its creep age distance.
Described box body is formed by glass fibre reinforced nylon thermoplastic injection mo(u)lding.
The thickness of described glass fibre reinforced nylon thermoplastic is 6～8mm.Too small its intensity that can affect of thickness is thick
Spend big then contraction meeting ratio more serious, and inside there will be bubble.
The contact box that the present invention provides, the design of sealing insulator is possible not only to meet the requirement of mechanical performance, and uses
Glass fibre reinforced nylon thermoplastic injection mo(u)lding, gained contact box product is without ftractureing, disclosure satisfy that high-voltage switch sets
The standby requirement to contact box.Meanwhile, this contact box structure is compact, and formed product materials are few, and shaping efficiency is high, have lightweight,
Energy consumption is little, waste product material recoverable, the advantage of environmental protection.
The switchgear of the present invention be the technical scheme is that a kind of switchgear, including contact box and dynamic and static touch
Head, described contact box is included barrel type insulation body and is connected to the sealing insulator of barrel type insulation body one end by transition shoulder, envelope
Being provided with static contact in mouth insulator and install inserts, described static contact is installed the outer rim of inserts and is extended at transition shoulder.
It is spherical structure that described static contact installation inserts deviates from the surface of barrel type insulation body side.
It is spherical structure that described sealing insulator deviates from the surface of barrel type insulation body side, the spherical structure of sealing insulator
The spherical structure installing inserts with static contact is arranged concentrically, or the spherical structure of sealing insulator installs inserts with static contact
The centre of sphere line of spherical structure and the dead in line of barrel type insulation body.Described transition shoulder has the step transition of annular setting
Section.
It is the umbrella handle mushroom construction towards barrel type insulation body that described static contact installs inserts.
The switchgear that the present invention provides, the consumption of contact box used is light, and material environment friendly is good, reduces switchgear
Cost, improves the safety and stability that switchgear runs.
