Description
Technical field
What the present invention relates to is the protection housing, and concrete is appearance looks elegant, and electric property is good, a kind of easily instrument transformer special isolation of fabrication and installation protective case.
Background technology
The domestic at present and external 35kV that produces and the instrument transformer of following electric pressure adopt the poured with epoxy resin product mostly.The oil immersed type that adopts the poured with epoxy resin formula to produce has than before significantly reduced expense and the operation safeguarded.The related casting mold of poured with epoxy resin product is very many, and the pour mass outward appearance of watering out is not again very desirable, and, pour mass big as the tire seam be surperficial scuffing etc.This just needs manually to go in a large number to repair, but final effect is not as not patched place.Also meaning has simultaneously wasted great amount of manpower, has improved cost of manufacture virtually.And profile is not attractive in appearance yet.
Summary of the invention
The objective of the invention is to exist some shortcomings and problem at the product that present instrument transformer protective case adopts the mode of production of one-time cast-forming to produce, provide for this reason a kind of aesthetic in appearance, cost of manufacture is cheap, a kind of instrument transformer special isolation protective case of being convenient to install.
The technical scheme that adopts is:
A kind of instrument transformer special isolation protective case, protective case and back protective case before comprising; Protective case comprises procapsid, enterprising, the gap that portals of preceding bus before described, under the preceding bus into and out of the hole gap, before structure is identical secondary line go out, hand-hole gap and a plurality of block; The and arranged on left and right sides that bus is enterprising, the gap that portals is separately positioned on the procapsid top before described, the said structure and arranged on left and right sides that secondary line goes out, the hand-hole gap is separately positioned on the procapsid bottom before identical is separately positioned on the and arranged on left and right sides of procapsid bottom before above-mentioned under the bus into and out of the hole gap;
Above-mentioned back protective case comprises back casing, back bus enterprising, the gap that portals, and into and out of the hole gap, the back secondary line that structure is identical goes out, hand-hole gap and a plurality of draw-in groove under the back bus; The described back and arranged on left and right sides that bus is enterprising, the gap that portals is separately positioned on the back casing top, the bottom and arranged on left and right sides that the back secondary line that said structure is identical goes out, the hand-hole gap is separately positioned on back casing is separately positioned on the and arranged on left and right sides of back casing bottom into and out of the hole gap under the bus of above-mentioned back;
Above-mentioned a plurality of block is arranged on the stile of procapsid and arranged on left and right sides symmetrically.
On the stile that is arranged on the back casing and arranged on left and right sides of above-mentioned a plurality of draw-in groove symmetries.
Above-mentioned block and draw-in groove are for pegging graft, and block and draw-in groove adopt known technology to make, and block is that one is connected with forward and backward housing respectively with draw-in groove.
Using method of the present invention:
1, the instrument transformer with moulding by casting is installed in the concrete electric loop, the in-out end that is provided with the instrument transformer primary line in the top or the bottom of instrument transformer and the corresponding connection of in-out end of busbar, relevant indication in the in-out end that is provided with the instrument transformer secondary line in the bottom of instrument transformer and the concrete electric loop, loops such as control, metering go out, go into the terminals contact.
2, before instrument transformer is placed on, the centre of back protective case, advance, before going out bus and being positioned at, the upper end of back protective case or the left side of bottom, (busbar that instrument transformer protective case of the present invention is a different capabilities is provided with two kinds of busbars of the specification that varies in size and imports and exports in the right gap, be separately positioned on this protective case upper end and bottom, optional one in the concrete practicality), going out of secondary line, go into the secondary line left side that end is inserted protective case bottom, front and back, in the right gap, firmly push behind the protective case aligned position of front and back, before, the block and the draw-in groove of back protective case tightly are fastened togather, thereby become as a whole instrument transformer protective case.
Characteristics of the present invention
1, adopt connected mode, installation, the dismounting of butt joint very convenient.Need not safeguard that cost reduces greatly.
2, the protective case material adopts polyurethane to make, and whole electric property will be better than the protective case of general epoxide resin material cast far away.
3, aesthetic in appearance, generous.
Design science of the present invention, reasonable, original, compact overall structure, with low cost, stable performance, reliable, practicality is stronger, has development prospect preferably.Suitable industrial and mining enterprises, especially steel mill and power supply department use.
