Abstract
The invention discloses a lead structure of a photovoltaic transformer. The lead structure comprises a device body. The device body comprises an iron core and a winding. The device body is provided with two faces which are the high-voltage side face and the low-voltage side face respectively. The high-voltage side face comprises a main lead, and the main lead is led out towards the side face after being clamped and fixed through a wood part. The low-voltage side face is provided with a branching lead which is led towards the side face and connected to a branching switch, and the main lead and the branching lead are led out at the same time. The lead structure has the advantages that the main lead and the branching lead are let out at the same time so that the space occupied by the device body can be effectively reduced, the size of an oil tank is reduced, the use amount of steel and transformer oil can be reduced, the economical efficiency of the transformer is improved, meanwhile, the assembling efficiency of the transformer can be effectively improved through changes of the direction of an element, and labor cost is saved.
Description
Technical field
The present invention relates to photovoltaic transformer technical field, particularly relate to a kind of photovoltaic transformer pin configuration.
Background technology
Photovoltaic change is mainly used in photovoltaic type power station, and mainly bear the task of boosting, the reliability of photovoltaic type transformer and fail safe directly affect the safe operation of photovoltaic plant, and the pin configuration of transformer is one of key link affecting transformer reliability.The high and low pressure lead-in wire of current photovoltaic transformer all adopts the structure of both sides extraction, and namely high-voltage connection is drawn from high-pressure side, and low-voltage lead is drawn from low-pressure side.Both sides extraction can make part go between overlapping the intersection, and cause insulation hidden danger, existing photovoltaic transformer components and parts irrational distribution, device body integral thickness is large, and both sides are drawn and had to increase fuel tank volume, increase transformer cost; Both sides deriving structure adds installation difficulty, affects the structure aesthetic property that photovoltaic becomes.
Summary of the invention
For deficiency of the prior art, the invention provides a kind of photovoltaic transformer pin configuration, solve photovoltaic transformer installation effectiveness low, there is insulation hidden danger between components and parts, security reliability is low, the problem that cost is high.
The present invention is achieved through the following technical solutions.
A kind of photovoltaic transformer pin configuration, comprise a device body, described device body comprises iron core and winding, and described device status is two sides, is respectively high pressure side and low pressure side, described high pressure side comprises a main lead-in wire, described main lead-in wire by wooden pieces be fixedly clamped backward side draw, described low pressure side is provided with tap lead, and described tap lead is drawn to side, be connected to shunting switch, described main lead-in wire and tap lead are drawn in the same side.Main lead-in wire and tap lead draw the space effectively reduced shared by device body in the same side, and then reduce the volume of fuel tank, the consumption of steel and transformer oil can be reduced, promote the economy of transformer, originally the thickness of device body is by originally needing to reserve the thickness between tap lead and main lead-in wire, due to tap lead is arranged at low-pressure side, therefore the thickness of device body reduces greatly.
As preferably, described tap lead is soft copper bar body.Original employing be circle copper body, soft copper bar body can not be damaged by pressure in transportation, and from safer electric stability.
As preferably, described shunting switch is in the layout of device body side, and shape is bar shaped.Bar shaped is changed into, reduction oil mass by original cage type.
As preferably, the main lead-in wire of described high pressure side is clamped by wooden pieces, and described wooden pieces is groined type.Wooden pieces serves good insulating effect.
As preferably, described main lead-in wire and tap lead are all arranged with wrinkle paper tube.
As preferably, described wooden pieces is enclosed with insulating board, reinforced insulation.
As preferably, described main lead-in wire and tap lead junction all adopt cold pressure welding process.Can avoid welding the impacts such as the rosin joint, the welding slag that cause be residual, improve the reliability of welding, length bumpy transport can be born.
Compared with prior art: main lead-in wire and tap lead draw the space that can effectively reduce shared by device body in the same side, and then reduce the volume of fuel tank, the consumption of steel and transformer oil can be reduced, promote the economy of transformer, the change in components and parts orientation simultaneously can effectively promote transformer efficiency of assembling, saves labour turnover.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described further.
A kind of photovoltaic transformer pin configuration, comprise a device body, described device body comprises iron core and winding, described device status is two sides, be respectively high pressure side and low pressure side, described high pressure side comprises a main lead-in wire 1, described main lead-in wire 1 is drawn from winding, connect fuse 2, described fuse 2 is installed on the top of device body, described fuse 2 connected load switch 3, described on-load switch 3 joint sleeve 4, described main lead-in wire 1 by wooden pieces 7 be fixedly clamped backward side draw, described low pressure side is provided with tap lead 5, described tap lead 5 is drawn to side, be connected to shunting switch 6, described fuse 2, on-load switch 3, sleeve pipe 4 on the same line, described tap lead 5 is soft copper bar body, described shunting switch 6 is in the layout of device body side, shape is bar shaped, the main lead-in wire 1 of described high pressure side is clamped by wooden pieces 7, described wooden pieces 7 is in groined type, described main lead-in wire 1 is all arranged with wrinkle paper tube with tap lead 5, described fuse 2 is all enclosed with insulating board with wooden pieces, described main lead-in wire 1 and tap lead 5 junction all adopt cold pressure welding process.
Tap lead 5 is drawn from low-pressure side right side of face, and lead-in wire copper bar is fixed by clamp structure, the reliability gone between under can improving emergency case.
Fuse 2 is in the layout of the device side with it of transformer, can reduce the space shared by fuse 2 to greatest extent, facilitate cabling simultaneously, reduce the difficulty of installing, be also convenient to later stage operation maintenance.Shunting switch 6 adopts layout in transformer body side, can save fuel tank space.
Main lead-in wire 1 is drawn from low pressure side, fix backward side by wooden pieces 7 to draw, more current layout significantly can promote the electrical reliability of main lead-in wire 1, because side extraction structure effectively can shorten the length of main lead-in wire 1, avoid the juxtaposition between going between, stop the insulation hidden danger between going between.Described main lead-in wire 1 and tap lead 5 junction adopt cold-press process to be connected, can avoid welding the impacts such as the rosin joint, the welding slag that cause be residual, improve the reliability of welding, can bear length bumpy transport.
