Description
Technical field
The utility model relates to the instrument transformer technology, and especially electricity substation is used merge cells.
Background technology
At present in power transmission and transformation system; Obtaining mainly of high-tension current once or voltage signal realizes through traditional electromagnetic type curtage instrument transformer technology; Their secondary output is simulated High-power curtage signal, along with the increase of electric power required amount and the raising of electric pressure, makes that the volume of traditional electromagnetic type curtage instrument transformer is increasing; Cost is increasingly high, is therefore substituted by electronic mutual inductor gradually.
Like publication number is a kind of electronic mutual inductor merge cells of basis of CN 201780860; Comprise cabinet and inner merge cells circuit thereof; The merge cells circuit comprises cpu pcb and power supply circuit board, is provided with the electromagnetic shielding metallic plate between said cpu pcb and the power supply circuit board.This electronic mutual inductor merge cells is through increasing the electromagnetic shielding metallic plate between power supply circuit board and cpu pcb, though also can make merge cells have interference free performance, secondary output signal receives electromagnetic interference little.But still there is deficiency in this merge cells interference free performance, be difficult to resist the outside interference of merge cells, and its physics impact resistance is relatively poor.
Summary of the invention
The utility model technical problem to be solved provides a kind of merge cells housing, and capability of electromagnetic shielding is good, and anti-physical impact ability is strong.
For solving the problems of the technologies described above, the technical scheme of the utility model is: a kind of merge cells housing, comprise the back casing and the procapsid that cooperatively interact, and said procapsid and back casing are the aluminium alloy compression casting moulding; Said housing is provided with terminal.The moulding of whole machine using aluminium alloy compression casting, handsome in appearance generous, whole housing is divided into procapsid and back casing, and the two adopts screw to connect, and the entire product capability of electromagnetic shielding is good, and anti-physical impact ability is strong.
As improvement, said procapsid and back casing junction are provided with the silica gel water proof ring, improve the water resistance of merge cells, increase its life-span of using out of doors and fail safe.
As improvement, the junction of said terminal and housing is provided with the silica gel water proof ring, improves the water resistance of merge cells, increases its life-span of using out of doors and fail safe.
As improvement, be provided with the heat conduction aluminium flake in the said housing, said heat conduction aluminium flake contacts with housing.The heat that electronic component sends in the housing is delivered to through the heat conduction aluminium flake on the housing of metal, then by housing to extraneous distribute heat, to reach good heat radiation purpose.
As improvement, said housing is provided with radiating surface outward, and said radiating surface is provided with radiating ribs.Radiating surface can increase the area of dissipation of housing, further improves the heat-sinking capability of housing.
The beneficial effect that the utility model is compared with prior art brought is:
1, whole machine using aluminium alloy compression casting moulding, handsome in appearance generous, whole housing is divided into procapsid and back casing, and the two adopts screw to connect, and the entire product capability of electromagnetic shielding is good, and anti-physical impact ability is strong;
2, the junction of said procapsid and back casing junction and terminal and housing is provided with the silica gel water proof ring, improves the water resistance of merge cells, increases its life-span of using out of doors and fail safe;
3, the outer radiating surface of heat conduction aluminium flake in the housing and housing can improve the radiating effect of merge cells.

Fig. 2 is the utility model external structure sketch map.
Embodiment
Below in conjunction with Figure of description the utility model is described further.
Like Fig. 1, shown in 2, a kind of merge cells housing 3 comprises the back casing and the procapsid that cooperatively interact; Said procapsid and back casing are the aluminium alloy compression casting moulding, and the moulding of whole machine using aluminium alloy compression casting is handsome in appearance generous; Whole housing 3 is divided into procapsid and back casing; The two adopts screw to connect, and the entire product capability of electromagnetic shielding is good, and anti-physical impact ability is strong; Said procapsid and back casing junction are provided with silica gel water proof ring 5, improve the water resistance of merge cells, increase its life-span of using out of doors and fail safe; Screw is arranged distance evenly, and reasonable quantity makes water proof ring 5 stress equalizations, has strengthened the water proof and dust proof ability of housing.
Said housing is provided with terminal 1, and said terminal 1 is provided with the silica gel water proof ring with the junction of housing, improves the water resistance of merge cells, increases its life-span of using out of doors and fail safe.
Be provided with heat conduction aluminium flake 2 in the said housing 3, said heat conduction aluminium flake 2 contacts with housing 3; Be provided with radiating surface 4 outside the said housing 3, said radiating surface 4 is provided with radiating ribs.The heat that electronic components send in the housing 3 is delivered to through heat conduction aluminium flake 2 on the housing 3 of metal, then by housing 3 to extraneous distribute heat, to reach good heat radiation purpose; Radiating surface 4 can increase the area of dissipation of housing 3, further improves the heat-sinking capability of housing, has prolonged machine life.
