Description of drawings
Fig. 1 is equipped with the main TV structure schematic diagram of the underwater sealing box of transformer for the utility model;
Fig. 2 removes plan structure schematic diagram behind the lid for the utility model;
Fig. 3 is the structural representation of looking up of lid in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Referring to Fig. 1 to Fig. 3, the underwater sealing box that transformer is installed of the present utility model comprises box body 1, lid 2, two transformers 3, two insulating pads 4, wiring board 6 and bellowss 8.
Described box body 1 is rectangular configuration, and described lid 2 is the rectangular slab that is complementary with box body 1, and described box body 1 and lid 2 all adopt stainless steel or titanium alloy material to make.Adopt above-mentioned technical scheme, because the underwater sealing box is under water, need bear pressure, the metal material that stainless steel or titanium alloy are anticorrosion, withstand voltage, good heat dissipation, the process and assemble performance is good can reach the instructions for use of box body 1 and lid 2.Described box body 1 upper end-face edge is formed with lower seal groove cavity 101, and described lid 2 lower ends are formed with the last seal groove 201 corresponding with lower seal groove cavity 101.During installation, in described upper and lower seal groove 201,101, all be injected with liquid sealant, then sealing ring 9 is placed in the lower seal groove cavity 101, the last seal groove 201 aligning sealing rings 9 of described lid 2 are installed on the box body 1 and by bolt box body 1 and lid 2 are fixed tightly in together, finish at a distance of 0.5 millimeter slit up to box body 1 and lid 2, can see that liquid sealant is extruded and is full of the slit of 2 of box body 1 and lids this moment.Described sealing ring 9 is for adopting the fine integral sealing circle of fourth, integral sealing circle good sealing effect (no disconnecting place), consider that the underwater sealing box is put in the water, sealing ring 9 may produce and expand with heat and contract with cold, make sealing ring 9 and upper and lower seal groove 201,101 produce micro gap, so adopt the integral sealing circle to cooperate the liquid sealant sealing.The liquid sealant temperature influence is little, and colloid elasticity, plasticity can be filled up the micro gap of sealing ring and upper and lower seal groove 201,101 generations well.
Two described transformers 3 vertically are arranged on box body 1 inner bottom both sides symmetrically, and be equipped with an insulating pad 4 between two described transformers 3 and box body 1 inner bottom, one side of each described transformer 3 is connected with 5, two described cables 5 of a cable respectively and draws laterally the two side of hermetically passing box body 1 respectively.Be formed with one on described box body 1 two side respectively for two through holes that described cable 5 passes, all be sealed and installed with 10, two described cables 5 of gland head two side by corresponding gland head 10 hermetically passing box bodys 1 respectively on two described through holes.Preferably, two described gland head 10 all adopt IP68 level Ge Lan head.Adopt technique scheme, make by gland head 10 to have guaranteed the sealing in the underwater sealing box in two cables, 5 hermetically passing box bodys, 1 two side.
Described box body 1 inner bottom middle part is provided with a wiring board 6.
Pour into heat radiation oil and should heat radiation oily liquid level 7 in the described box body 1 highly all greater than the height of two described transformers 3.The utility model adopts the method for whole filling heat radiation oil in the box body, utilize the hot road of the inner free convection of characteristic realization box body of fluid itself, make the box body temperature even, and make the heat of transformer generation be delivered to box wall through free convection, finally be delivered in the water.This heat radiation oil be a kind ofly fully fluoridize, the specialty heat radiation oil of high thermal stability, high insulating property, be widely used in high-tension transformer and the supermicrocomputer.
Level is provided with a bellows 8 for the oily thermal volume expansion compensation of heat radiation on described box body 1 inner back wall, and this bellows 8 is immersed in the described heat radiation oil, and preferably, described bellows 8 is welded metal bellow.Because transformer long-term work in box body, the heat radiation oil temperature constantly rises, and volumetric expansion is risen the box body internal pressure.For solving the volume compensation that causes owing to expanding, designed the bellows that is used for the thermal volume expansion compensation.Internal pressure in the oily expanded by heating that dispels the heat, box body increases, and in the time of the bellows pressurized, forms reaction force, finally reaches balance pressure state, and at this moment, the heat radiation oil volume expands and absorbed by bellows fully.
During installation, two cables 5 are passed the gland head 10 on box body 1 two side respectively and connect with two transformers 3 in the box body 1.Successively respectively with bellows 8, insulating pad 4, transformer 3, wiring board 6 and tighten fixingly by fixed bolt and cooperating of hold-down nut, lock gland head 10 more then.The oil that will dispel the heat injects (heat radiation oil level 7 has certain distance apart from box body 1 upper edge) in the box body 1, liquid sealant is clamp-oned respectively in the upper and lower seal groove 201,101, again sealing ring 9 is put into lower seal groove cavity 101, to go up seal groove 201 aims at sealing ring 9 and is pressed into, tighten in order with bolt at last, finish at a distance of 0.5 millimeter slit up to box body 1 and lid 2, can see that liquid sealant is extruded and is full of slit between box body and lid this moment.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but these embodiment are included within the scope of the present utility model.
