Description
Technical field
The invention belongs to field of electrical equipment, relate to transformator, particularly relate to a kind of hanging-rod type small electrical and become
Depressor.
Background technology
Transformator be the principle utilizing electromagnetic induction to change the device of alternating voltage, main member is primary line
Circle, secondary coil and iron core (magnetic core).Major function has: voltage transformation, current transformation, impedance transformation, every
From, voltage stabilizing (magnetic saturation transformator) etc..Transformator divides according to the type of cooling: 1) dry-type transformer: rely on sky
Gas convection current carry out natural cooling or increase blower fan cooling, be used for skyscraper, high speed toll station electricity consumption and
The small capacity transformer such as local lighting, electronic circuit.2) oil-filled transformer: rely on oil make cooling medium,
Such as oil, oil, oil immersed water cool, forced oil-circulation etc..Wherein, oil-filled transformer, main
Fuel tank to be included, fuel tank is also the shell of transformator, and built-in iron core and winding are also full of transformer oil, make ferrum
Core and winding are immersed in oil.Transformer oil plays insulation and thermolysis.High-power transformer typically has two fuel tanks,
One is body fuel tank；One for there being load to wither force feed case, on-load voltage regulation fuel tank is built with shunting switch.This is
Because shunting switch can produce electric arc in operation, if carrying out frequent operation will make the insulating properties of oil
Decline, therefore set a single fuel tank shunting switch is individually placed.Common oil tank of transformer is held by it
The size of amount, has box fuel tank, bell type tank and 3 kinds of basic patterns of sealed fuel tank, wherein, seals
Formula fuel tank is after device body general assembly is fully completed loading fuel tank, is not to connect by bolt between its upper nowel edge,
But be welded directly together, form an entirety, thus realize the sealing of fuel tank.Due to this fuel tank
Structure is welding as one, if therefore scene needs suspended core maintenance will be the most inconvenient；So this transformator transports to existing
And run duration the most do not carry out suspended core maintenance, this will the quality of changes persuing depressor should hold good security.
Along with the raising of transformer manufacturing level, sealed construction is the most gradually used, and more both domestic and external big
Type transformator also has started to use this structure.
At present, the installation of existing small distribution transformator more use double-rod stand install, this mounting means have with
Lower shortcoming: 1, cost is higher, for less than 50 kilovolt-amperes transformators, this kind is installed adnexa used and is worth super
Cross transformator itself.2, take up an area face valency relatively big, region is installed limited.3, installation is inconvenient.
Summary of the invention
The present invention is directed to the technical problem that above-mentioned small distribution transformator exists, propose a kind of reasonable in design,
Simple in construction, the hanging-rod type compact electrical transformers that with low cost and easy for installation, floor space is little.
In order to achieve the above object, the technical solution used in the present invention is, the present invention provides a kind of hanging-rod type little
Type power transformer, including sealing the fuel tank arranged, is provided with device body general assembly, described fuel tank in described fuel tank
Top be provided with high tension terminal, described high tension terminal is obliquely installed forward, and described fuel tank also sets up
Having low tension terminal, described low tension terminal to be arranged on the bottom of fuel tank, the back of described fuel tank is provided with peace
Dress seat, described mounting seat is provided with the installation anchor ear being matched therewith, described mounting seat with install anchor ear it
Between removably connect.
As preferably, the back of described fuel tank is provided with the groove matched with electric pole, and described mounting seat is arranged
Both sides at groove.
