Description
Technical field
The present invention relates to transformer more particularly to a kind of transformers for setting cooling mechanism and being detachably connected umbrella and can mowing.
Background technology
Transformer is the device for changing alternating voltage using the principle of electromagnetic induction, and main member is winding（It is i.e. primary
Coil, secondary coil）And iron core（Magnetic core）.Major function has：Voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing（Magnetic
Saturation transformer）Deng.It can be divided into, according to use,：Power transformer and special transformer（Electric furnace change, rectification change, industrial frequency experiment become
Depressor, pressure regulator, mining change, audio-frequency transformer, intermediate-frequency transformer, high frequency transformer, impact transformer, instrument transformer, electricity
Sub- transformer, reactor, mutual inductor etc.）.Existing transformer has the following disadvantages：It can not be hidden using at outdoor
Sun, aging speed are fast；It needs artificial removal careless when growing grass by transformer, manually goes weeding safety by transformer poor；Only pass through
Radiator radiates, and heat dissipation effect is poor.
Invention content
The present invention provides it is convenient when a kind of good heat dissipation effect, installing and dismounting umbrella and can mow to set cooling mechanism removable
Unload the transformer that Connectable umbrella can mow, solve existing transformer lack sun-shading mechanism, needs it is artificial go installation point weeding and
Only by radiator radiate existing heat dissipation effect it is poor the problem of.
More than technical problem is solved by following technical proposal：One kind sets cooling mechanism and is detachably connected umbrella and can mow
Transformer, including transformer body, the transformer body includes the shell equipped with transformer oil, is provided in the shell
The iron core and winding being submerged in transformer oil, which is characterized in that external rotor electric machine, umbrella and cooling mechanism are further included, it is described outer
