Description

A kind of Special underwater transformer

Technical field

The utility model relates to a kind of transformer manufacture technology, and more particularly, it relates to a kind of Special underwater transformer.

Background technology

Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).Major function has: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) etc.By purposes, can be divided into: distribution transformer, power transformer, full-sealed transformer, combined transformer, dry-type transformer, oil-filled transformer, single-phase transformer, furnace transformer, rectifier transformer etc.

At present, in order to adapt to the workplace of various varying environments, the appearance on market a kind of Special underwater transformer, because if transformer is placed in control cubicle on the bank, transformer is away from the electrical appliance of underwater operation, and the electric current after step-down in circuit can increase, thereby increases energy consumption.

Wherein, application number is that 201120484653.3 Chinese patent discloses a kind of Special underwater transformer, it comprises iron core and is wrapped in wire winding conducting wire two ends on iron core input and the output of connection transformer respectively, described in be wrapped in wire on iron core and make to be provided with the conductor wire of water-proof jacket; The input of described transformer and output are located at respectively in airtight box body, described box body consists of upper cover and lower cover, the lower cover of box body has the wiring hole that wears wire, and described wire is connected with the terminals in box body by wiring hole, between wire and wiring hole, is provided with sealing ring.

Although this Special underwater transformer has added water-proof jacket in coil windings, than original waterproof effect better, more reliable,, only by above-mentioned change, the radiating effect of transformer itself is not had to much liftings; And, use for a long time under water, although specific heat of water holds greatly, heat absorption capacity is strong, Chang Zuowei coolant, can be because water is hot non-conductor, radiating rate is slow, the underwater environment not circulating at some, ambient temperature is high, after transformer raises the water temperature of periphery by heat radiation, water can not distribute self heat in time, causes transformer water temperature around high, causes transformer to dispel the heat nowhere, finally burn out Inside coil, particularly powerful transformer is not more easily because internal temperature obtains discharging and burning out in time.
