Abstract
The invention relates to a pad device for a transformer. The pad device comprises an upper pad and a lower pad which are arranged in an embedded structure, and is characterized in that: the upper pad has a first upper pad platform, an upper pad boss, a second upper pad platform, an upper pad groove and a positioning groove; a groove with a creepage distance is arranged around the upper pad; the lower pad has a first lower pad platform, a lower pad boss, a second lower pad platform, a lower pad groove and a positioning groove; and a groove with a creepage distance is arranged around the lower pad. The pad device has the advantages of simple, compact and rational structure, convenient assembly, low cost, economy, practicality, safety, reliability, and good electric performance, and can effectively increase the creepage distance, so that the electric strength and insulating strength against the ground of the pad device and the short-circuit resisting capability of the transformers can be greatly improved; and raw materials can be saved, and the weight and the size of the pad are reduced.
Description
Technical field
The present invention relates to pad device for transformer, specifically a kind of novel transformer insulating part belongs to the power transformer technical field.
Background technology
In prior art, transformer insulated cushion block normally improves creepage distance between coil and the folder by the height that increases cushion block, what the very high creepage distance that increases that the cushion block of the transformer that voltage is high just need be done, cushion block were totally given the people feels it is the comparison heaviness, and assembling is inconvenient.The level and smooth polishing in original cushion block side, creepage distance is little, needs very high cushion block just can reach creepage distance, and compare consumptive material aspect raw material.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of pad device for transformer, can increase effective creepage distance, strengthened the anti-short circuit capability of its electric strength, insulation against ground intensity and transformer greatly, simultaneously can save raw material, alleviate the weight and volume of cushion block, assemble more convenient.
According to technical scheme provided by the invention, pad device for transformer comprises cushion block and lower cushion block, describedly goes up cushion block and lower cushion block is the setting-in structure, and feature is: on described cushion block be provided with cushion block platform on first, on cushion block platform on the cushion block boss and second; Described going up on the cushion block offers cushion block groove and location notch; Be provided with the groove of creepage distance around the described upward cushion block.
Described lower cushion block is provided with the first lower cushion block platform, lower cushion block boss and the second lower cushion block platform; Offer lower cushion block groove and location notch on the described lower cushion block; Be provided with the groove of creepage distance around the described lower cushion block.The described groove width that goes up cushion block creepage distance groove, lower cushion block creepage distance groove is: 10 centimetres, groove depth is: 5 centimetres, be spaced apart between the per pass groove: 40 centimetres.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Easy to assembly, with low cost, economical and practical, safe and reliable, good electric property can effectively increase creepage distance; Strengthen the anti-short circuit capability of its electric strength, insulation against ground intensity and transformer greatly, can save raw material simultaneously, alleviated the weight and volume of cushion block.

Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 5: comprise upper clamping piece 1, go up cushion block 2, insulating cylinder 3, lower cushion block 4, iron core 5, low-voltage coil 6, lower clamping piece 7, high-tension coil 8 etc.
Cushion block 2 and lower cushion block 4 are the setting-in structure in the present invention, described on cushion block 2 be provided with cushion block on first platform 2-1, on cushion block platform 2-5 on the cushion block boss 2-2, second, and offer cushion block groove 2-3 and location notch 2-6 thereon.The described cushion block 2 of going up is provided with creepage distance groove 2-4 all around.Described lower cushion block 4 is provided with the first lower cushion block platform 4-1, lower cushion block boss 4-2, the second lower cushion block platform 4-5; And offer lower cushion block groove 4-3 and location notch 4-6 thereon.Be provided with creepage distance groove 4-4 around the described lower cushion block 4.The described groove width that goes up cushion block creepage distance groove 2-4, lower cushion block 4 creepage distance groove 4-4 is: 10 centimetres, groove depth is: 5 centimetres.Be spaced apart between the per pass groove: 40 centimetres.
When the present invention used, last cushion block 2 and lower cushion block 4 were contained between iron core 5, upper clamping piece 1, lower clamping piece 7, low-voltage coil 6 and the high-tension coil 8.
Lower cushion block 4 positions by location notch 4-6 and lower clamping piece 7, by the second lower cushion block platform 4-5 high-tension coil 8 is positioned then, 4-3 positions insulating cylinder 3 by the lower cushion block groove, place insulating cylinder 3 after, by the first lower cushion block platform 4-1 low-voltage coil 6 is positioned.
Last cushion block 2 positions by location notch 2-6 and upper clamping piece 1, after placing high-voltage coil and low-voltage coil 8 and insulating cylinder 3, using cushion block platform 2-5 positions high-tension coil 8, the platform 2-1 of cushion block positions low-voltage coil 6 on first, last cushion block groove 2-3 fixes insulating cylinder 3, simultaneously the fixing distance between high-voltage coil and low-voltage coil of boss 2-2, the lower cushion block boss 4-2 by last cushion block.Then with press nail by lower cushion block location notch 4-6, go up cushion block location notch 2-6 and compress lower cushion block, go up cushion block, thereby fixedly high-voltage coil and low-voltage coil 8 and insulating cylinder 3.
Owing to around lower cushion block 4, be provided with creepage distance groove 4-4; Be provided with creepage distance groove 2-4 around the last cushion block 2, its creepage distance can increase greatly, has also alleviated cushion block weight simultaneously, has reduced production cost.
