[0019] The isolation grounding device 2 includes an isolation transformer 10, an epoxy resin encapsulation sleeve 11, a first conductive connector 12, a grounding electrode 13, a protective sleeve 14 and a second conductive connector 15. The epoxy resin encapsulation sleeve 11 is arranged on the outside of the isolation transformer 10, one end of the first conductive connector 12 is fixedly installed at the output end of the isolation transformer 10 by bolts, and the other end of the first conductive connector 12 is fixedly installed at the working end of the grounding electrode 13 by bolts. The protective sleeve 14 is nested on the outside of the first conductive connector 12, and one end of the second conductive connector 15 is fixedly installed at the input end of the isolation transformer 10 by bolts.

[0020] The isolation transformer 10 is placed inside the support frame 6 to prevent the vibration of the distribution box 3 from causing the connection point of the isolation transformer 10 to be disconnected. The second conductive connector 15 passes through the inside of the second isolation sleeve 8, and the end of the second conductive connector 15 away from the isolation transformer 10 is fixed to the grounding plate 9 by bolts. The second conductive connector 15 is isolated by the second isolation sleeve 8 to avoid contact with the distribution box 3 to generate cross-current.

[0021] The isolation transformer 10 is encapsulated in the epoxy resin encapsulation sleeve 11 , and the isolation transformer 10 is insulated and protected by the encapsulation to avoid short circuit damage.

[0022] The supporting isolation pad 4, the first isolation sleeve 5, the second isolation sleeve 8 and the protective pipe sleeve 14 are all made of insulating rubber material, which effectively protects the grounding line from external current interference.

When the electrical equipment or distribution box is energized and the electrical equipment generates electromagnetic waves, the charge and electromagnetic waves are transmitted to the isolation transformer 10 through the second conductive connector 15. The isolation transformer 10 transfers the charge and electromagnetic waves to the first conductive connector 12. The charge and electromagnetic waves in the first conductive connector 12 are transmitted to the earth through the grounding electrode 13, thereby achieving the protection effect of the electrical equipment. When there is electricity in the earth, it is reversed through the grounding electrode 13. During transmission, the current is blocked when passing through the isolation transformer 10, thereby protecting the electrical equipment. The support isolation pad 4 blocks the contact between the distribution box 3 and the ground. When the distribution box 3 is connected to the current, the current is transmitted to the second conductive connector 15 through the grounding plate 9. The first isolation sleeve 5 is used to block the connection between the second conductive connector 15 and the distribution box 3. The second isolation sleeve 8 is used to block the connection between the first conductive connector 12 and the distribution box 3 to prevent the current from flowing through and losing the grounding effect. The epoxy resin encapsulation sleeve 11 wraps the isolation transformer 10 by plastic sealing to prevent the surface contact current of the isolation transformer 10 from damaging the isolation transformer 10.
