Description
Technical Field
[0001] The utility model relates to the technical field of explosion-proof transformers, in particular to a five-column iron core of a mine-used explosion-proof transformer. Background Art
[0002] At present, mining explosion-proof dry-type transformers are generally used in mines with methane mixed gas, combustible dust and explosion hazards. Due to the limitations of underground conditions, mining explosion-proof dry-type transformers generally adopt air self-cooling, and heat dissipation mainly relies on convection and thermal radiation. In specific use, the existing transformer core needs to use an iron core to carry the iron core and metal wire windings, but the existing five-column iron core is not stable and has weak protection against sand and stone impact. For this reason, we propose a five-column iron core for mining explosion-proof transformers. Utility Model Content

[0024] Example 2, please refer to the attached Figure 1 -Attached Figure 5 The utility model provides a technical solution: a five-column iron core of a mine flameproof transformer, comprising an iron core column 1, a fixing mechanism 2 is installed on the outer surface of the iron core column 1, a protective mechanism 3 is installed on the top of the iron core column 1, the fixing mechanism 2 comprises a fixing base 21, a fixing rod 22, a fixing plate 23 and a baffle 24, a threaded hole 5 is opened on the top of the fixing base 21, the fixing rod 22 is installed in the threaded hole 5, two groups of card slots 6 are opened on the top of the fixing rod 22, the fixing plate 23 is clamped in the card slot 6, and a limiting hole 7 is opened at the bottom of the baffle 24.
[0025] Please refer to the attached Figure 1 -Attached Figure 5The protection mechanism 3 includes a top plate 31, a rubber spring group 32, a protection plate 33, a straight plate 34 and a support plate 35. Four groups of limiting grooves 8 are provided on the top of the top plate 31 and the bottom of the protection plate 33. The rubber spring group 32 is located in the limiting grooves 8.
