Abstract
The utility model relates to an underwater special transformer, comprising an iron core and a lead wire winding around the iron core. The both ends of a lead wire are respectively connected with an input end and an output end of the transformer; the lead wire wound on the iron core is a conduction wire provided with a waterproof protecting bush; the input end and the output end of the transformer are arranged in a sealed box body; the box body consists of an upper cover and a lower cover; the lower cover of the box body is provided with a wiring hole provided with the lead wire in a penetrating manner; the lead wire is connected with a wiring end in the box body through a wiring hole; and a sealing ring is arranged between the lead wire and the wiring hole. Compared with the prior art, a coil winding of the transformer provided by the utility model uses a waterproof protecting bush wire, so that no water leakage phenomenon is generated, the waterproof property is better, and the reliability is higher. Furthermore, the heat radiation effects of the transformer are obvious, the energy consumption of the transformer is reduced, and the service life of the transformer is prolonged.
Description
Technical field
The utility model relates to transformer, and especially a kind of coil windings adopts the dedicated transformer under water of water-proof jacket line.
Background technology
At present, the transformer that uses under water generally is a box body of common transformer integral body being put into sealing, reaches the purpose of waterproof.Its shortcoming is following: the one, and the transformer radiating effect that is placed in the sealing box body is bad, and long-time use burns out coil easily, and particularly powerful transformer burns out more easily.The 2nd, in a single day the sealing of box body lost efficacy, and water causes transformer short-circuit after getting into, thereby can not work.
If transformer is placed on the bank control refuses, transformer is away from the electrical appliance of underwater operation, and the electric current after the step-down in the circuit can increase, thereby energy consumption increases.
The utility model content
The purpose of the utility model provides a kind of good heat dissipation effect, waterproof is reliable, and coil windings adopts the dedicated transformer under water of water-proof jacket line.
The purpose of the utility model realizes through adopting following technical scheme:
Dedicated transformer comprises iron core and is wrapped in the lead winding on the iron core under water, and the lead two ends connect the input and the output of transformer respectively, and the said lead that is wrapped on the iron core is the conductor wire that is provided with water-proof jacket; The input of said transformer and output are located at respectively in the airtight box body; Said box body is made up of loam cake and lower cover; The lower cover of box body has the wiring hole that wears lead, and said lead is connected with the interior terminals of box body through wiring hole, is provided with sealing ring between lead and the wiring hole.
As the optimal technical scheme of the utility model, the metal-cored outer surface of said lead is provided with insulating coating, and insulating coating is provided with water-proof jacket outward.
As the optimal technical scheme of the utility model, said lead comprises copper enamelled wire or aluminium enamel-covered wire, and said enamelled wire skin also is provided with the PVC sheath.
As the optimal technical scheme of the utility model, said lead is copper core RVV or aluminium core RVV.
As the optimal technical scheme of the utility model, said sealing ring is an O type rubber seal.
The beneficial effect of the utility model is: with respect to prior art, the coil windings of the utility model transformer adopts the water-proof jacket line, can not produce drainage, and water resistance is better, and reliability is higher; And the radiating effect of transformer is remarkable, and energy consumption reduces, longer service life.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the utility model RVV.
Embodiment
As depicted in figs. 1 and 2, dedicated transformer comprises iron core 1 and is wrapped in the lead winding 2 on the iron core 1 under water, and lead 3 two ends connect the input and the output of transformer respectively, and the said lead 3 that is wrapped on the iron core is the conductor wires that are provided with water-proof jacket.The input of said transformer and output are located at respectively in the airtight box body 4; Said box body 4 is made up of loam cake and lower cover; The lower cover of box body 4 has the wiring hole that wears lead 3, and said lead 3 is connected with box body 4 interior terminals through wiring hole, is provided with sealing ring between lead 3 and the wiring hole.
In the present embodiment, the metal-cored outer surface of said lead 3 is provided with insulating varnish, metal-cored copper and the aluminium of comprising, and promptly lead 3 is copper enamelled wire or aluminium enamel-covered wire, the skin of enamelled wire is provided with PVC sheath 32.As another kind of execution mode, said lead 3 also can adopt copper core RVV or aluminium core RVV.The said sealing ring of present embodiment is an O type rubber seal; The input of said transformer and output adopt and are fixed on terminal screw or the connection bolt 5 on the insulation board; Be provided with sealing ring between the loam cake of box body 4 and the lower cover, loam cake is connected sealing with lower cover through screw bolt and nut.
Claims (5)
