Abstract
A non-encapsulation dry type transformer low voltage high current phase row clamping equipment is characterized in that the utility model comprises an upper clamping piece and at least three insulated boards; a phase row is arranged between the neighboring insulated boards; the insulated board and the phase row are fixed on the upper clamping piece through a penetrated core screw, an insulated pipe, a gasket, a nut and an elastic cushion. When using the utility model, the electric and mechanical intensity of the non-encapsulation dry type transformer is improved; when happens a sudden short circuit, the damage action of the transformer structure produced by the mechanical force can be eased, the safe and reliable performances of the non-encapsulation dry type transformer are improved.
Description
One, technical field
The utility model belongs to the transformer accessory technical field, and particularly a kind of no-encapsulated-winding dry-type transformer low-voltage, high-current that is applicable to is arranged fixing no-encapsulated-winding dry-type transformer low-voltage, high-current phase row folding mutually and tightly installed.
Two, background technology
As shown in Figure 3, the tight device of the phase row folding of existing no-encapsulated-winding dry-type transformer routine is by full line screw rod one 11a fixed insulation one 13b on upper clamping piece, between insulator one 13b and insulator two 13a, accompany and arrange 22 mutually, the three also connects by full line screw rod two 11b, arrange one 1 mutually and directly be fixed on insulator two 13a, thereby the low pressure phase row folding that has formed no-encapsulated-winding dry-type transformer tightly installs by bolt 14, packing ring and bullet pad.This pin configuration is arranged compact, safety, can fully guarantee product reliability service under this electric pressure.Along with pushing forward comprehensively of China's modernization, the urbanization degree further strengthens, and particularly big city and super large city are densely populated, and industry and commerce is concentrated, and power load is high, thereby big capacity, low-voltage grade transformer are directly goed deep into the urban district load center.Along with the continuous increase of transformer capacity, its low-voltage rated electric current also increases thereupon, and the sudden short circuit mechanical force that product bore also further increases, and the clamping device that original low pressure is arranged mutually can not fully guarantee the operation that transformer is safe and reliable.
Three, summary of the invention
The utility model provides a kind of improved no-encapsulated-winding dry-type transformer low-voltage and high-current phase row folding tightly to install at the potential safety hazard of existing no-encapsulated-winding dry-type transformer, realizes the layout that low-voltage, high-current is arranged mutually by this device.
Technical solution of the present utility model is, a kind of no-encapsulated-winding dry-type transformer low-voltage, high-current phase row folding tightly installs, comprise upper clamping piece and at least 3 insulation boards, be provided with mutually row between the insulator that faces mutually, above-mentioned insulator and arranging mutually by punching screw rod, insulated tube, packing ring, nut and bullet pad is fixed on the upper clamping piece.
The utility model has been optimized the structural design of product, in use, improved electric, the mechanical strength of no-encapsulated-winding dry-type transformer, when running into sudden short circuit, can alleviate the destruction of mechanical force, improve fail safe, the reliability of no-encapsulated-winding dry-type transformer transformer device structure.
