Description

A kind of transformator
Technical field
This utility model is related to a kind of transformator.
Background technology
Transformator is the device for changing alternating voltage using the principle of electromagnetic induction, and main member is primary coil, secondary Level coil and iron core(Magnetic core).Major function has:Voltage transformation, current transformation, impedance conversion, isolation, voltage stabilizing(Magnetic saturation transformation Device)Deng.Can be divided into, according to use,:Power transformer and special transformer(Electric furnace change, rectification change, power frequency testing transformer, pressure regulation Device, mining change, audio-frequency transformer, intermediate-frequency transformer, high frequency transformer, impact transformator, instrument transformer, electronic transformer, Reactor, transformer etc.).
Transformator is by iron core(Or magnetic core)With coil composition, coil has two or more windings, wherein connecing power supply Winding primary coil, remaining winding is secondary coil.It can convert alternating voltage, electric current and impedance.It is simplest Made by a soft magnetic materials unshakable in one's determination of iron-core transformer and two numbers of turn being enclosed within iron core coil not etc. is constituted, unshakable in one's determination Effect is to strengthen the magnetic coupling between two coils.In order to reduce vortex and magnetic hystersis loss in ferrum, iron core is by the silicon steel sheet stack painted Pressure is formed;Without the contact of electricity between two coils, coil is by insulated copper wire(Or aluminum steel)It is coiled into.One coil connects alternating current power supply Referred to as primary coil(Or primary coil), another coil connects electrical appliance and is referred to as secondary coil(Or secondary coil).Actual transformator It is very complicated, is inevitably present copper loss(Coil resistance generates heat), iron loss(Iron core heating)And leakage field(Jing air closure Magnetic induction line)Deng, in order to simplify discuss only introduce ideal transformer here.Ideal transformer set up condition be:Ignore leakage field It is logical, ignore the resistance of former and deputy coil, ignore the loss of iron core, ignore no-load current(The electricity that secondary coil is opened a way in primary coil coil Stream).Such as power transformer is in full-load run(Secondary coil exports rated power)I.e. close ideal transformer situation.
At present existing transformer insulated effect is bad, not with heat sinking function, installs inconvenient.
The content of the invention
It is good that the technical problems to be solved in the utility model is to provide a kind of insulation effect, easy for installation with heat sinking function Transformator.
To solve the above problems, this utility model is adopted the following technical scheme that:
A kind of transformator, including iron yoke, iron core column, winding and casing, the winding is arranged on iron core column outside, the ferrum Yoke is arranged in casing, and annular fixing member and porcelain vase are provided with the casing, and the annular fixing member is enclosed within porcelain vase outside, institute State annular fixing member two ends and be provided with fixing bolt, the fixing bolt is connected through annular fixing member with casing, the porcelain vase In hollow setting, binding post is installed in the porcelain vase, the binding post is connected through casing with winding, the iron yoke bottom peace Equipped with rubber slab, described casing one end is provided with radiator fan, and the casing other end is provided with chamber door, and the chamber door middle part sets Air vent is equipped with, rain cover is installed on the chamber door on the outside of the air vent.
Preferably, the iron core column is located at iron yoke two ends, iron core column is integrally formed with iron yoke.
Preferably, the rubber slab is connected with casing gluing, rubber slab is kept to firmly install.
Preferably, described chamber door one end is provided with hinge.
Preferably, the chamber door is connected by hinge with casing, facilitate the regulation of chamber door.
Preferably, being provided with drainage screen in the rain cover, drainage screen is prevented from debris and falls into air vent.
The beneficial effects of the utility model are:The porcelain vase of setting and rubber slab keep insulation effect good;The radiation air of setting Fan can be radiated;Binding post is installed, binding post is connected through casing with winding in the porcelain vase of setting, keeps installation side Just;The air vent of setting facilitates the discharge of steam, keeps good heat dissipation effect;The rain cover of setting have be covered in function.
