AI Technical Summary
The existing 110kV cable terminal joints have poor connection stability and are prone to separation due to vibration or contact. Furthermore, the lack of ventilation leads to excessively high internal temperatures in the connection ring.
The design includes a fixing component and a ventilation component. The fixing component uses a combination of clips, slots, T-shaped rods, and springs to securely connect the connector to the connecting ring. The ventilation component uses a dustproof plate and hex bolts to fix the dustproof plate, achieving ventilation, cooling, and dust prevention.
It achieves a firm connection between the connector and the connecting ring, avoiding poor contact, and prevents the internal temperature of the connecting ring from getting too high through ventilation and cooling, while allowing external air to enter for heat dissipation and preventing impurities from entering.
