Description
Technical field:
The present invention relates to transformer low-voltage lead structural applications, be specially a kind of photovoltaic power generation transformer low voltage lead structure.
Background technology:
Current most of photovoltaic transformer low pressure is twin voltage, namely low-voltage coil is axial direction double bundle structure, connection connects for " D " or " Y " connects, low-voltage copper bar lead-in wire is made to lift one's head to oil tank wall sleeve pipe quantity more: coil upper semisection 3, lower semisection 3 (having zero phase time to be respectively 4 up and down).It is intricate that low-voltage lead copper bar walks, most of guiding on the right side of A phase coil more upwards outlet after horizontal for lower semisection low-voltage copper bar to fuel tank sleeve pipe in the market, this structure occupies more space, in order to walk out copper bar and ensure electrical safety distance, have to increase fuel tank width (copper bar is wider, and the width that fuel tank adds is more), thus add the consumption of copper bar and transformer oil, improve product cost, moreover be exactly that the horizontal outlet of copper bar is bad fixing, mechanical strength is poor.
Summary of the invention:
The object of the present invention is to provide a kind of photovoltaic power generation transformer low voltage lead structure, it has saved resource, reduces product cost, strengthens product quality, improves product competitiveness in the market.
For achieving the above object, the invention provides following technical scheme: a kind of photovoltaic power generation transformer low voltage lead structure, comprise transformer core assembly parts, low-voltage coil c phase, low-voltage coil b phase, low-voltage coil a phase, the first electrical laminated wood wire clamp for fixing low-voltage lead copper bar, the second electrical laminated wood wire clamp, the 3rd electrical laminated wood wire clamp, the first lead-in wire copper bar, the second lead-in wire copper bar and the 3rd lead-in wire copper bar; Described first lead-in wire copper bar, the second lead-in wire copper bar and the 3rd lead-in wire copper bar are respectively the lead-out wire of low-voltage coil a phase, low-voltage coil b phase and low-voltage coil c phase; Described first lead-in wire copper bar, the second lead-in wire copper bar and the 3rd lead-in wire copper bar are all arranged on low-voltage coil b phase and low-voltage coil a phase intermediate gaps position; Described first lead-in wire copper bar, the second lead-in wire copper bar and the 3rd lead-in wire copper bar are fixed by described second electrical laminated wood wire clamp; Described first electrical laminated wood wire clamp and the 3rd electrical laminated wood wire clamp are fixed by bolts to all for two sections low-voltage lead copper bars on the steel plate that is welded on folder channel-section steel.
As further technical scheme of the present invention: described transformer core assembly parts are fixedly mounted on low-voltage coil c phase, low-voltage coil b phase and low-voltage coil a phase upper end.
As further technical scheme of the present invention: described 3rd lead-in wire copper bar moves towards all to be parallel to fuel tank tank wall between high-tension coil, and overlap straight up.
Compared with prior art, the invention has the beneficial effects as follows: this photovoltaic power generation transformer low voltage lead structure, utilize two phase coil intermediate gaps, be used for arranging the outlet of low-voltage coil lower semisection copper bar.Secondly, utilize AB phase coil intermediate gaps to be parallel to oil tank wall all for low pressure lower semisection copper bars of upwards drawing and vertically stack together, finally again with the composite conductor folder of electrical laminated wooden work each copper bar is fixed on be welded in device body folder steel plate on.
Not only this pin configuration compact but also attractive in appearance, and associative perception is very strong, not in a jumble.Reduce the length of fuel tank width, transformer oil and each lead-in wire copper bar greatly, enhance transformer whole mechanical strength and anti-short circuit capability.Present invention saves resource, reduce product cost, strengthen product quality, improve product competitiveness in the market.
