Description
Technical field
The utility model belongs to high pressure transmission ＆ distribution electro-technical field, and in particular to a kind of gas-insulated with particle trap is high
Press equipment.
Background technology
Gas-insulated high-voltage system is the metal shell by being grounded, and centre has the conductor for flowing through high-tension current and support to lead
Body simultaneously allows conductor to be formed with the insulator that grounding shell insulate, and fills sulfur hexafluoride SF6 gases or SF6 gaseous mixtures in metal shell
Body.Since high-tension apparatus needs to connect different equipment, also the distance between equipment difference, need to make conductor segments
It makes.In order to ensure that two conductors are reliably connected and by high current, current is typically that two conductors are added transition by centre
The contact of electric current connects.
When being connected with contact, since high-tension apparatus passes through the of different sizes of electric current, also daily environment temperature in operation
Degree changes sooner or later, can all cause the phenomenon of expanding with heat and contract with cold of equipment conductor.The contact of conductor connection in this way will rub conductor,
The material of conductor or contact itself is caused to have abrasion fines to fall off.In addition most of contact is silver-plated, conductor contact site
It is silver-plated, silver-plated poor quality will cause silvered face to fall off, and fall inside equipment, cause inside gas-insulated high-voltage system
There is the metal fillings generated because of abrasion.
Because of gas-insulated high-voltage system ability reliability service under high-cleanness environment, if because wearing, expanding with heat and contract with cold
Etc. reasons cause its internal metal fillings occurred, metal particle that can seriously affect the built-in field distribution of equipment, cause equipment
Electric discharge, to damage equipment.
Currently, the Faraday cage particle trap of some producers design, it can allow the pressure test at the scene of some particles
When allow particle to jump into Faraday cage particle trap by heightening test voltage, achieve the purpose that limit particle.But it is this
Particle trap has certain limitation：1) it can be used only in the occasion of equipment level installation；As long as equipment angle mount, the particle in trap
It can skid off, be damaged to apparatus insulated；2) equipment cannot shake.Particle can also be shaken by vibrations from faraday cup.Particle
The high electromagnetic field for coming back to high-tension apparatus, causes high voltage equipment insulation to discharge, and damages high-tension apparatus.
Utility model content
For the above problems of the prior art, the utility model proposes a kind of gas with particle trap
Body Insulating A High-Voltage equipment, including contact base, conductive contact, shielding case, moving contact conductor, contact base are touched by conductive contact with dynamic
Head conductor is connected；Further include shielding case, shielding case is located at contact base and moving contact conductor coupling portion, and setting in shielding case
There is particle structure of trap.
Preferably, according to the installation direction of contact base and moving contact conductor, determine particle structure of trap in shielding case
Position.
Preferably, particle structure of trap is constituted by the way that jelly is arranged in the inside of shielding case.
Preferably, jelly has the long-term characteristic for keeping viscosity.
Preferably, jelly has anti-flammability.
Preferably, jelly will not be chemically reacted with sulfur hexafluoride SF6 and its decomposition product.
For the particle structure of trap of gas-insulated high-voltage system, it is arranged inside the shielding case of proximate contacts, leans on glue
The viscosity of shape object clings the metal and non-metal particle for touching and being generated when the metal fillings worn or installation, makes these metals or non-
Metal particle will not become scattered about in high-tension apparatus, high-tension apparatus be damaged so as to avoid apparatus insulated electric discharge is caused, to pole
The earth improves the performance of high-tension apparatus.
The characteristics of jelly of the utility model also resides in it can keep viscosity for a long time, it is applied in table in shielding case
Face, and the surface is zero electric field region.Whether the conduction of the jelly itself, shadow is not constituted to the performance of the particle structure of trap
It rings.
Hereafter by a manner of clearly understandable, preferred embodiment is described with reference to the drawings, to the above-mentioned characteristic of the utility model,
Technical characteristic, advantage and its realization method are further described.

In order to which the technical features, objects and effects to utility model are more clearly understood, now control illustrates this
The specific implementation mode of utility model, in the various figures identical label indicate that structure is identical or structure is similar but the identical portion of function
Part.
Herein, " schematic " expression " serving as example, example or explanation " should not will be described herein as " showing
Any diagram, the embodiment of meaning property " are construed to a kind of preferred or more advantageous technical solution.
To make simplified form, only schematically shown in each figure with the relevant part of the utility model, they are not
Represent its practical structures as product.In addition, to make simplified form be easy to understand, there is identical structure or work(in some figures

Herein, "one" not only indicates " only this ", can also indicate the situation of " more than one ".Herein
In, " first ", " second " etc. are only used for mutual differentiation, rather than significance level and the sequence etc. for indicating them.
Specific embodiment of the present utility model is described in detail with reference to Fig. 1.
As shown in Figure 1, a kind of gas-insulated high-voltage system, contact base 01, conductive contact 02, shielding case 03, moving contact are led
Body 04 and shielding case 03, contact base 01 are connected by conductive contact 02 with moving contact conductor 04.Shielding case 03 is located at contact
Seat 01 and 04 interconnecting piece of moving contact conductor.When moving contact conductor 04 is inserted into conductive contact 02, or expands with heat and contract with cold and cause dynamic touch
When head conductor 04 slides, rubs the metal fillings to get off between moving contact conductor 04 and conductive contact 02 or metal particle will be fallen
03 inside of shielding case, by the way that in the inside of shielding case 03 setting particle structure of trap, these metal fillings or metal particle are captured,
High-tension apparatus is damaged to avoid them from causing the processes such as electric discharge into other electrification positions of gas-insulated high-voltage system.
Such particle structure of trap can be by being applied to the shielding case covered near conductive contact 02 by jelly 05
03 inside and constitute, jelly 05 can cling above-mentioned metal fillings or metal particle.
Preferably, it can determine that particle structure of trap is shielding according to the installation direction of contact base 01 and moving contact conductor 04
The position for covering 03 inside of cover is still arranged vertically, metal fillings will not all drop out shielding case in this way no matter conductor is horizontally disposed
03。
Because the kelvin effect of electric current, electric current are flowed through in conductive surface, so the internal electric intensity of shielding case 03
It is zero.So whether jelly 05 is conductive, the effect of particle is captured on this kind of particle trap not to be influenced.
Preferably, jelly 05 is with the long-term characteristic and anti-flammability for keeping viscosity.Because of gas insulated high voltage
If equipment includes sulfur hexafluoride SF6, decomposed can occur in some cases in its operational process, therefore excellent
Selection of land, jelly 05 will not be chemically reacted with sulfur hexafluoride SF6 and its decomposition product.
