Abstract
The utility model relates to a bus connector rubber sleeve for a cabinet-type gas-insulating metal closed switch device. The bus connector rubber sleeve comprises an external shielding sleeve, an insulating layer and an internal shielding sleeve, middle parts of the external shielding sleeve and the insulating layer are each designed to be the shape of an arc drum, the external shielding sleeve is molded by injecting a semiconducting silicon rubber material and is optimized by an advanced electric field software, two ends of the external shielding sleeve are respectively provided with protruding steps so as to be pressed tightly and fixed, and the internal shielding sleeve is a sprayed coating. The cabinet-type gas-insulating metal closed switch device using the bus connector rubber sleeve for cabinet combination can automatically compensate and regulate installation deviation, the installation is simple and convenient, and the quality is reliable; and meanwhile, good insulation and protection properties can are realized, and reliability and safety of the device are improved.
Description
Technical field:
The utility model relates to the insulating part technical field of using in the cabinet type Cubicle Gas-Insulated Switchgear, refers in particular to a kind of bus connector gum cover.
Background technology:
In the process that the design and installation of cabinet type Cubicle Gas-Insulated Switchgear are used, connecting method between cabinet and the cabinet, the design of insulating part are selected for use and the control of installation quality, it is the emphasis that product design personnel and project installation personnel consider always, this is that its technical merit directly has influence on the fail safe and the reliability of integral device because insulating part is one of link that the most easily breaks down in the entire equipment.Existing bus connector gum cover: 1. the middle part of product is designed to the straight line tubbiness.This design is very unfavorable for the assembly cabinet of cabinet type Cubicle Gas-Insulated Switchgear, because not flexible, the deviation compensation that produces during installation is not, so neutrality is required between cabinet and the cabinet is high, project installation personnel are wasted time and energy in order to eliminate these deviations, simultaneously, and in order to reduce these deviations, must carry out strict control to the dimensional tolerance of cabinet processing, thereby increase the processing cost of cabinet.2. outer shielding layer is formed through spray process by the semiconductive silastic material.Because the screen of spraying is very thin, be generally less than 0.2mm, its adhesive force in time passing and obviously reduce, easy to wear, come off, and anti-soil is not dirty, the time has been grown, variation has taken place in the sheet resistance of screen, earth fault will occur, have a strong impact on the barrier propterty of product, shorten the useful life of product greatly.3. do not have design that the flange step is arranged, the fixing location by cabinet of bus tie guarantees.When displacement appears in cabinet, when the spacing between the cabinet changed, because not flexible of middle part, the interface insulation coordination between bus tie and the bus-bar insulator will be affected, and caused the accident of creeping discharge or insulation breakdown.So, the key of technical quality level when a kind of novel bus connector gum cover of development and Design is the cabinet type Cubicle Gas-Insulated Switchgear assembly of raising cabinet.
Summary of the invention:
The purpose of this utility model is to overcome the weak point of existing product technology, a kind of bus connector gum cover is provided, use this bus connector gum cover piece together the cabinet type Cubicle Gas-Insulated Switchgear of cabinet can self-compensating and regulate installation deviation, simple installation, reliable in quality, have good insulation property and barrier propterty simultaneously, improve the reliability and the fail safe of equipment.
For achieving the above object, the technical scheme that the utility model provides is: be made of external shroud, insulating barrier, internal shield, the middle part of external shroud and insulating barrier is designed to the circular arc drum type, external shroud adopts the semiconductive silastic material through injection moulding, and the electric field computed in software through the advanced person is optimized, the step that projection is designed at its two ends respectively works the effect of being secured in a press, and internal shield is a sprayed coating.
After the utility model adopts said structure, bus connector gum cover has self-compensating and regulatory function, cabinet type Cubicle Gas-Insulated Switchgear is in the process of piecing together cabinet, the installation deviation that is difficult to eliminate appears sometimes, bus connector gum cover is by the design feature of self, can compensate and regulate these deviations effectively, make installation easier, quality is more reliable.External shroud adopts injection molding technique, solved bring by spraying coating process easy to wear, come off and product hidden danger such as the surface electrical resistive is big as sprayed coating, improved the barrier propterty of bus tie, simultaneously, by the step at external shroud two ends, bus tie is fixed on the equipment tightly, guarantees the interface insulation coordination between itself and the bus-bar insulator, make integral device have good insulation property, reliability and fail safe are higher.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is pieced together the structural representation of cabinet for using the utility model.
Embodiment:
Below in conjunction with a preferred embodiment and accompanying drawing thereof the utility model is described further.
As shown in Figure 1, present embodiment is made of external shroud 1, insulating barrier 2, internal shield 3, the middle part of external shroud 1 and insulating barrier 2 is designed to circular arc drum type 4, external shroud 1 adopts the semiconductive silastic material through injection moulding, the step 5 of projection is designed at its two ends respectively, and internal shield 3 is a sprayed coating.After the utility model adopts said structure, bus connector gum cover 6 has self-compensating and regulatory function, as shown in Figure 2, when installation deviation appears in cabinet type Cubicle Gas-Insulated Switchgear 7 when piecing together cabinet, bus connector gum cover can compensate and regulate these deviations effectively by the design feature of self, alleviates project installation personnel's labour intensity, make to install to become easier, quality is more reliable.Because the external shroud of bus connector gum cover adopts injection molding technique, greatly improved the barrier propterty of bus tie and even integral device, simultaneously, step by the external shroud two ends, bus tie is fixed on the equipment tightly by pressing plate 8, even the interface insulation coordination that guarantees itself and bus-bar insulator 9 also has good insulation property under the situation that occurs the certain displacement amount between the cabinet, the operation of integral device is more stable, and reliability and fail safe are higher.
The embodiment of the above only is preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so all equivalences of doing according to shape of the present utility model, structure and principle change, and all should be covered by within the protection range of the present utility model.
