Description
Technical field
This utility model relates to technical field of electric equipment, particularly relates to a kind of all-sealed solid insulated switchgear。
Background technology
In recent years, solid insulation ring main unit, as a kind of novel distribution net equipment, is just being widely applied in urban distribution network and the upgrading of rural power grids。Volume is little, security reliability is high, non-maintaining, not emission hazard gas so that it is is better than SF6 gas-insulated cabinet, and is approved by more client。But meanwhile, circuit breaker case sealing is general, and equipment performance and reliability are easily affected by environment, and the insulating part existed between isolation fracture and ground connection fracture punctures or flashover, also becomes the problem demanding prompt solution of chopper own。
The isolation fracture of solid insulated switchgear and ground connection fracture generally adopt dry air to realize, and essence is the static contact seat at fracture two ends, moving contact seat to be arranged on same insulating part。When switch is in gate-dividing state, the insulating properties between sound touch base are by the air between sound touch base, the together deciding on along face creep age distance of insulating part。This structure deposits problem both ways。It is that fracture exists insulating part edge flashing factor on the one hand, adds fracture chance of breakdown, and fracture punctures or flashover will make major loop have a power failure。Insulator material is aging simultaneously, along the decline of the increase of face leakage current, insulating properties, it will product reliability is produced impact。Isolation fracture and ground connection fracture adopt dry air on the other hand, also cannot monitor its degree of drying during service life。
Solid insulation ring main unit major part is arranged in metal or the non-metal box body of open air, and due to bad environments degree varies, box body tightness is general, and equipment dependability and performance are easy to affected by environment。By chemical substance in moisture, dust, the temperature difference and air, it may appear that phenomenons such as product zero corrosion, condensations, thus reducing the service life of cupboard。
Utility model content
The purpose of this utility model is to provide a kind of all-sealed solid insulated switchgear, is truly realized the hermetically sealed of chopper, thus solving the adverse effect because moisture, dust, condensation etc. bring, adds the service life of solid insulated switchgear。
To achieve these goals, this utility model have employed following technical scheme: a kind of all-sealed solid insulated switchgear, and including a mechanism case, described mechanism case includes protecgulum, upper cover, bonnet, two side covers；
Described upper cover and protecgulum, bonnet, side cover are all tightly connected, and junction is equipped with box sealing circle；
Described protecgulum is provided with several sealing flanges and Sealed Observation Window；
Covering on described equipped with secondary wiring terminals, described secondary wiring terminals is provided with terminal protecting cover；
Described bonnet is connected to porcelain insulator, and porcelain insulator is connected with a seal case, is provided with full skirt pull bar in casing, and casing is connected with a solid insulation cylinder。
Wherein, noble gas can be filled with in described mechanism case。
The beneficial effects of the utility model: all-sealed solid insulated switchgear has improved from breaker structure aspect, removing conventional chopper secondary outgoing line end need in the situation of breaker operation cabinet perforate, secondary wiring terminals is adopted circuit breaker internal wiring to be directly led out in the electric cabinet of outside, simultaneously, all insulating parts and casing external connections at chopper cavity both increase insulating sealer, further seal, it is truly realized the hermetically sealed of chopper, thus solving the adverse effect because moisture, dust, condensation etc. bring。
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment technical scheme, below the accompanying drawing used required during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only that this utility model is in order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below the accompanying drawing used required in p-embodiment or description of the prior art is briefly described, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings。
Fig. 1 is structural representation of the present utility model。
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments。Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection。
A kind of all-sealed solid insulated switchgear as shown in Figure 1, including a mechanism case 8, described mechanism case 8 includes protecgulum 9, upper cover, bonnet, two side covers；Described upper cover and protecgulum 9, bonnet, side cover are all tightly connected, and junction is equipped with box sealing circle 6；Described protecgulum 9 is provided with several sealing flanges 1 and Sealed Observation Window 7；Covering on described equipped with secondary wiring terminals 2, described secondary wiring terminals 2 is provided with terminal protecting cover 3；Described bonnet is connected to porcelain insulator, and porcelain insulator is connected with a seal case, is provided with full skirt pull bar 4 in casing, and casing is connected with a solid insulation cylinder 5。
All-sealed solid insulated switchgear adopts the isolation pull bar with full skirt device, greatly strengthen it along face creep age distance, significantly reduces the edge flashing factor of insulating part, decrease fracture breakdown probability。Simultaneously, owing to adopting the complete sealing in galvanic circle in solid insulation cylinder 5, and secondary connection is compared with traditional secondary line protection set, have employed sealed secondary wiring terminals 2, add whole casing at each position to external connecting, all have employed rubber seal, ensure that casing and outside are completely isolated, all-sealed can be filled with noble gas in whole mechanism case 8, such as nitrogen, carbon dioxide etc., intensity can well be replied by change medium and increase electrical apparatus insulation performance, and antisepsis can also be well played in the change of medium, a small amount of desiccant is added in the casing of this sealing, sponge the moisture of box house, condensation problem can well be solved, the very big lifting for the reliable realization that chopper uses in High aititude and difference variation larger area。
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model。
