The first line concentration cover and the second line concentration cover are both made by combining a refractory plate and a lining plate. The explosion-proof protection device separates the low-voltage wiring area and the high-voltage wiring area, mutual interference is avoided, wiring is kept independent and neat, the overall fire-resistant and flame-retardant performance is excellent, the cooling effect is achieved, safe use of the device is guaranteed; meanwhile, multiple sets of cables are connected in independent channels, and dust-proof, damp-proof and anti-creeping protection of the wiring end is provided.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof wiring of transformers, and in particular relates to an explosion-proof protection device for wiring of a transformer body. Background technique [0002] The transformer is used to transform the AC voltage and current. When working, it is connected to the low-voltage line and the high-voltage line respectively, and the excitation effect is generated by the connected alternating current, and the alternating magnetic flux is generated in the iron core. The alternating magnetic flux passes through the primary side and the Secondary side winding, and induce electromotive force in the two windings respectively. When the load of the external circuit is connected, at this time, the AC current flows out to output electric energy. In order to ensure the safety of the wiring of the transformer body, it is necessary to assemble the wiring explosion protection When the existing wiring explosion-proof ...

[0002] The transformer is used to transform the AC voltage and current. When working, it is connected to the low-voltage line and the high-voltage line respectively, and the excitation effect is generated by the connected alternating current, and the alternating magnetic flux is generated in the iron core. The alternating magnetic flux passes through the primary side and the Secondary side winding, and induce electromotive force in the two windings respectively. When the load of the external circuit is connected, at this time, the AC current flows out to output electric energy. In order to ensure the safety of the wiring of the transformer body, it is necessary to assemble the wiring explosion protection When the existing wiring explosion-proof protection device is in use, the low-voltage wiring area and the high-voltage wiring area are not separated, resulting in mutual interference and poor wiring integrity. The overall fire resistance and flame retardancy are poor and there is no cooling effect. , which affects the safe use of the device. At the same time, the connection of multiple sets of cables is not carried out in an independent channel, and the dust-proof, moisture-proof and leakage-proof protection effects of the terminals are not good.
