Abstract
The utility model relates to the technical field of auxiliary equipment for power industry transmission lines and relates to equipment protection for low-voltage current transformers, in particular to a rain cover for current transformers. Power supply equipment installed outdoors, such as a low-voltage straight-through current transformer, is exposed throughout the year, a housing of cast epoxy resin is corroded, rain and the like enter the equipment, and accordingly, metering accuracy is affected and the failure rate is higher. According to the technical scheme, the rain cover is characterized in that a rain cover body is a square shell with a downward opening and is composed of a top plate, long side plates, short side plates and waterproof plates; the top plate of the shell is provided with mounting holes; the long side plates are fixedly connected to left and right sides of the top plate, the short side plates are fixed to the front and rear of the top plate, and the lower edges of the short side plates are connected with the waterproof plates. The rain cover has the advantages that the structure is simple, the cost is low, the outdoor straight-through current transformers are better protected, corrosion of the transformers due to environmental factors such as rain and snow is prevented, the service life of the equipment is prolonged, and failure rate is lower.
Description
Technical field
The utility model relates to power industry transmission line auxiliary equipment technical field, for the equipment protection of low-voltage current mutual inductor, and a kind of current transformer rain cover specifically.
Background technology
In power engineering power marketing class electric energy metrical special equipment, particularly be arranged on outdoor equipment, as low pressure straight-through current transformer casing insulation material is the epoxy resin casting type, outer through wind owing to being exposed to throughout the year, rain erosion, cause the poured with epoxy resin shell corrosion of instrument transformer, seasonal variations, the impact of the natural cause such as cold and heat succeed each other, make on instrument transformer to occur rimala, add rainwater, the immersion device interior of snow-broth, it is accurate that impact is measured, increase failure rate, there is certain potential safety hazard, the short circuit of current transformer generation internal structure even occurs when serious, explosion, device security and personal safety are threatened.
Summary of the invention
The purpose of this utility model is to provide a kind of current transformer rain cover, and the low-voltage ring epoxy resins casting straight-through current transformer for the protection of the open air assembling, prevent the erosion of the environmental factors such as rain, snow to instrument transformer.
The technical solution of the utility model is: protecting cover, for the quadrangle housing that Open Side Down, is comprised of top board, long side plate, short side plate and splash guard; The top board of housing has installing hole; Long side plate is fixed on the top board left and right sides, and short side plate is fixed on both sides, top board front and back, and splash guard is fixed on the lower limb of short side plate.
Further, the outer ledge of described splash guard is lower than inside edge.
The utility model has the advantages that: simple in structure, cost is lower, be arranged on low pressure straight-through current transformer top, block sleet, effectively prevent the erosion of environmental factor to instrument transformer equipment, reduce the equipment fault caused because of natural conditions, extended service life of equipment, reduced the operating cost of power department.
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is elaborated.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use state diagram of the present utility model.
Embodiment
In figure: 1, top board, 2, installing hole, 3, long side plate, 4, short side plate, 5, splash guard, 6, straight-through current transformer.
Embodiment
As can be seen from Figure 1, the utility model protecting cover is the quadrangle housing that Open Side Down, top board 1, long side plate 3, short side plate 4 and splash guard 5, consists of; Top board 1 is of a size of 15cm * 12.5cm, has installing hole 2 on top board 1, and the aperture of installing hole 2, spacing are identical with aperture and the spacing of straight-through current transformer 6 base fixing holes; Long side plate 3 is fastened on top board 1 left and right sides, is highly 11cm; Short side plate 4 is fixed on top board 1 both sides, front and back, is highly 4cm, to avoid blocking the cable punching hole of straight-through current transformer; Short side plate 4 lower limbs are provided with horizontal splash guard 5, and the outer ledge of splash guard 5 is lower than inside edge, form the eaves body of ramped shaped, and rain, snow-broth trickle along inclined-plane, prevent the stream such as rainwater, splash on current transformer, and transformer device is formed to effective protection.
When the utility model is installed, bolt is through the installing hole 2 of protecting cover top board 1 and the fixing hole of straight-through current transformer 6, the straight-through current transformer 6 and the protecting cover that are installed with cable are assemblied on transmission line cross-arm, the long side plate 3 of protecting cover is positioned at the cable both sides, make straight-through current transformer 6 be positioned at protecting cover, form blindage around reaching above instrument transformer, the erosion that prevents rainwater causes the equipment accidental short circuit to damage, extend the useful life of metering device, reduced failure rate.
Finally should be noted that: above embodiment is for illustrating that the technical solution of the utility model is not intended to limit; the those skilled in the art modifies to execution mode or the part technical characterictic is equal to replacement; and do not break away from the essence of technical solutions of the utility model, within all should being encompassed in the utility model scope required for protection.
