Description

Protector in a kind of mechanism case of transformer station or coupling box
Technical field
The utility model relates to power plant equipment field, relates in particular to protector in a kind of transformer station mechanism case.
Background technology
Each transformer station and power plant primary cut-out, the mechanism case of isolating switch and indoor and outdoor coupling box are absolutely necessary, be in operation, mechanism case is arranged on outdoor, circuit breaker is controlled, because it is electric equipment, easily be subject to outside climatic influences, existing mechanism case adopts Plate Welding to form, on rainy day or when there was dampness in the air, due to the tight the occurrence of wetness of casing inner sealing, terminal board corrosion oxidation is serious and atmosphere draught-free overheating fault is more and more, existing casing has ventilating opening, owing to having referred to draught effect, cause the interior electric component contamination by dust of casing serious, the corrosion of crust shutter is serious, insect is is arbitrarily come in and gone out, particularly in the rain or in rain rear box, have a condensation phenomenon, to electric power system, cause serious threat, easily cause protection misoperation in mechanism case.
Summary of the invention
The purpose of this utility model is to provide a kind of mechanism case or interior protector of coupling box of transformer station, at mechanism case chamber door opening part, shutter is set, sealing ring is set on shutter, then at sealing ring place, set gradually woollen layer, spongy layer, stainless steel screen pack, there is anti-gray, temperature adjustment, ventilative effect, add drier and there is the effect of filtering humid air.
For achieving the above object, the utility model is realized by the following technical solutions:
Protector in a kind of mechanism case of transformer station or coupling box, comprise stainless steel shutter, rubber seal, woollen layer, spongy layer, stainless steel screen pack, drier, rubber seal is arranged on stainless steel shutter surrounding, on stainless steel shutter, set gradually woollen layer, spongy layer, stainless steel screen pack is arranged on spongy layer and fixes with stainless steel shutter, between spongy layer and stainless steel screen pack, places packed drier.
The stainless-steel sheet thickness of described stainless steel shutter is 0.05cm~0.08cm.
The described high 12cm~16cm of stainless steel shutter, wide 10~15cm.
Described stainless steel screen pack mesh fineness is 300~800 orders.
Described drier is silica-gel desiccant.
Compared with prior art, the beneficial effects of the utility model are:
Can keep the mechanism case of primary cut-out, isolating switch and coupling box inner drying is clean and tidy, temperature is suitable, very convenient and practical during use, also reduced O&M personnel's workload, saved manpower financial capacity, improved security civilization reliable power supply, minimizing accident occurs, and ensures personal safety.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Fig. 2 is that the utility model is arranged on closing effect figure after coupling box.
Fig. 3 is that the utility model is arranged on coupling box back pullout (BPO) design sketch.
The woollen layer of 1-stainless steel shutter 2-rubber seal 3-4-spongy layer 5-stainless steel screen pack 6-drier
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further illustrated:
As shown in Figure 1, protector in a kind of mechanism case of transformer station or coupling box, by stainless steel shutter 1, rubber seal 2, woollen layer 3, spongy layer 4, stainless steel screen pack 5 and drier 6, formed, rubber seal 2 is arranged on stainless steel shutter 1 surrounding, on stainless steel shutter 1, set gradually woollen layer 3, spongy layer 4, stainless steel screen pack 5 is arranged on spongy layer 4 fixing with stainless steel shutter 1, between spongy layer 4 and stainless steel steel screen pack 5, places packed drier 6.The stainless-steel sheet thickness of stainless steel shutter 1 is 0.05cm~0.08cm; High 12cm~the 16cm of stainless steel shutter 1, wide 10~15cm; Stainless steel screen pack 5 mesh fineness are 300~800 orders; Drier 6 is silica-gel desiccant.
As shown in Figure 2 to 3, the utility model is arranged on the door of mechanism case or coupling box, the door lower left corner or the lower right corner are arranged to an opening, by the utility model with screw be bolted to opening part, outside shutter partly rushes, rubber seal 2 is arranged on to stainless steel shutter 1 surrounding, play sealing function, then on stainless steel shutter 1, set gradually woollen layer 3, spongy layer 4, woollen layer 3 thickness can be adjusted according to the temperature requirements of mechanism case or coupling box, spongy layer 4 thickness also can be adjusted according to the temperature requirements of mechanism case or coupling box, spongy layer 3 is due to himself characteristic, can there is ventilative effect, make mechanism case or coupling box circulation of air, stainless steel screen pack 5 is arranged on spongy layer, can play fixation to woollen layer 3, spongy layer 4, but also play the effect of circulation of air, can select according to the actual requirements width of mesh, between spongy layer 4 and stainless steel steel screen pack 5, place packed drier 6, this drier is silica-gel desiccant, belong to physical dryness agent, can absorb moisture, maintaining body case or coupling box dry, moisture-proof anticorrosive.
