Enclosed type generating line jack box

The utility model discloses an enclosed type generating line jack box, including grafting box and solenoid valve, the grafting box includes voltage transformer, and the voltage transformer embedding sets up in sending out the grafting box, and the solenoid valve includes the electro -magnet, and the electro -magnet embedding sets up in the solenoid valve, and the winding of the outer wall of electro -magnet has enamelled coil, and the inner wall of grafting box is provided with the solenoid valve, and the solenoid valve welds in the grafting box, and the front portion of grafting box is provided with the chamber door, and chamber door swing joint is on the grafting box. This kind of enclosed type generating line jack box, through voltage transformer, back in inserting the inside power of jack box becomes the low -voltage current that the solenoid valve can be accepted with the high -pressure current switchover on the circuit to having played the effect of protection solenoid valve, through the inside electro
